Any Idea how to to fix this issue in IE7?
Thanks in advance. | ## Add a wrapper element
<URL>
If editing the HTML source code is an option, add a wrapper element around the side content, and place it before the main text content. Then add 'position:relative' to the wrapper element rather than adding it to '.listitem'. This moves the local stacking context (created at an inconvenient time in IE7) to an element where it does no harm.
'''
<div class="container">
<div class="listitem">
<div class="wrapper">
<div class="layer">I'm a layer</div>
</div>
Some long content here bla bla blaaaaaaa baaaaaaaaaaa
</div>
....
</div>
'''
'''
.listitem {
/* position: relative; */ /* Removed here */
....
}
.wrapper {
position: relative; /* Added here */
height: 0;
}
'''
## jQuery
If editing the HTML source code isn't an option, there are a few options available using jQuery.
1. Take the basic approach presented by @avrahamcool (setting the z-index of each .listitem to a decreasingly small value). The downside to this approach is that it reverses the layering order of the side elements relative to one another, which may or may not be acceptable.
2. Use jQuery to edit the HTML DOM so that the HTML is as shown above, using the related CSS changes as well. The downside to this approach is that the styling of the content won't render correctly until after the jQuery code has run. So the content may briefly appear broken when the page first loads.
3. Set .container to position:relative, rather than .listitem. Use jQuery to calculate the relative position of each of .listitem element within .container, and set the top position of each side element based on this. This approach has the same downside as solution #2.
4. In an extreme case, if even editing the JavaScript isn't an option, you could simulate solution #1 by adding a series of increasingly long CSS selectors with decreasing z-index values (as shown below). I don't recommend this approach, as it's wildly impractical, but it could be used as a last resort.
'''
.listitem {z-index:99;}
.listitem + .listitem {z-index:98;}
.listitem + .listitem + .listitem {z-index:97;}
...
'''
## Conclusion
In short, the current HTML doesn't support this type of layout in IE7. The only elegant solution is to change the HTML source code to something that does support it. Any jQuery solution will tend to be awkward in one way or another. | |

Normally, when you define a public object/var in Unity C#, it shows up in the inspector or default references where you can drag something to it.
Here's my test code:

using System.Collections;

I tried several options, wrote the thing in MonoDev as also in Visual Studio, put all my files in an namespace, w and w/o Serializable attribe but.. What could be wrong?
Thanks for help! | Yes you do need to attach it to a gameObject in the scene in order to show the public members in the property inspector, since your script inherits from MonoBehaviour.
This is what I got.
<IMAGE>
Additionally, you cannot expose static members in the property inspector - even when marked as SerializableAttribute. System.SerializableAttribute is not valid on this declaration type. It is valid on 'class, struct, enum, delegate' declarations only.
In relation to your comment about requiring a globally accessible script with objects, you have a couple options, such as

Thank you.
<IMAGE> | It looks like you're using Swing, and if your question is how to get a game loop out of an application using the basics of Swing (an application not using BufferStrategy, but a combination of different Swing components), then you roughly want the following:
- - -
The custom JComponent you create can have listeners on various buttons or other things such as mouse clicks, where you can use the same reference to the game state object you use to draw to update the game's state based on the UI actions.
Make sure your code is thread safe too as the repaint executing on the EDT, or one of your Swing listeners, can occur at the same time you update your state with the Timer object.
If you search online for example usage of game loops in Java using BufferStrategy you'll find more traditional game loop examples. | |

You should tweak the above values as you see fit in the range of '[0, 1]'.

14,429,203 | 1 | 14,431,571 | So I'm working on a node.js game server application at the moment, and I've hit a bit of a wall here. My issue is that I'm using socket.io to accept inbound connections from game clients. These clients might be connected to one of several Zones or areas of the game world.
The basic architecture is displayed below. The master process forks a child process for each Zone of the game which runs the Zone Manager process; a process dedicated to maintaining the Zone data (3d models, positions of players/entities, etc). The master process then forks multiple "Communication Threads" for each Zone Manager it creates. These threads create an instance of socket.io and listen on the port for that Zone (multiple threads listening on a single port). These threads will handle the majority of the game logic in their own process as well as communicate with the database backing the game server. The only issue is that in some circumstances they may need to communicate with the Zone Manager to receive information about the Zone, players, etc.
<IMAGE>
As an example: A player wants to buy/sell/trade with a non-player character (NPC) in the Zone. The Zone Communication thread needs to ask the Zone Manager thread if the player is close enough to the NPC to make the trade before it allows the trade to take place.
The issue I'm running into here is that I was planning to make use of the node.js cluster functionality and use the 'send()' and 'on()' methods of the processes to handle passing messages back and forth. That would be fine except for one caveat I've run into with it. Since all child processes spun off with 'cluster.fork()' can only communicate with the "master" process. The node.js root process becomes a bottleneck for all communication. I ran some benchmarks on my system using a script that literally just bounced a message back and forth using the cluster's Inter-process Communication (IPC) and kept track of how many relays per second were being carried out. It seems that eventually node caps out at about 20k per second in terms of how many IPC's it can relay. This number was consistent on both a Phenom II 1.8ghz quad core laptop, and an FX-8350 4.0ghz 8-core desktop.
Now that sounds pretty decently high, except that this basically means that regardless of how many Zones or Communication Threads there are, all IPC is still bottlenecking through a single process that acts as a "relay" for the entire application. Which means that although it seems each individual thread can relay > 20k IPCs per second, the entire application as a whole will never relay more than that even if it were on some insane 32 core system since all the communication goes through a single thread.
So that's the problem I'm having. Now the dilemma. I've read a lot about the various other options out there and read like 20 different questions here on stack about this topic and I've seen a couple things popping up regularly:
<URL>
I'm actually running Redis on my server at the moment and using it as the socket.io datastore so that socket.io in multiple threads can share connection data so that a user can connect to any of N number of socket.io threads for their Zone so the server can sort of automatically load balance the incoming connections.
My concern with this is that it runs through the network stack. Hardly ideal for communication between multiple processes on the same server. I feel like the latency would be a major issue in the long run.
<URL>
I've never used this one for anything before, but I've been hearing a bit about it lately. Based on the reading I've done, I've found a lot of examples of people using it with TCP sockets, but there's not a lot of buzz about people using it for IPC. I was hoping perhaps someone here had worked with 0MQ for IPC before (possibly even in node.js?) and could shine some light on this option for me.
<URL>
Again I've never used this, but from what I've seen it looks like it's another option that is designed to work over TCP which means the network stack gets in the way again.
<URL>
Someone linked this in another question on here (which I can't seem to find again unfortunately). I've never even heard of it, and it looks like a very small solution that opens up and listens on UDP connections. Although this would probably still be faster than TCP options, we still have the network stack in the way right? I'm definitely like about a mile outside of my "programmer zone" as is here and well into the realm of networking/computer architecture stuff that I don't know much about lol
Anyway the bottom line is that I'm completely stuck here and have no idea what the best option would be for IPC in this scenario. I'm assuming at the moment that 0MQ is the best option of the ones I've listed above since it's the only one that seems to offer an "IPC" option for communication protocol which I presume means it's using a UNIX socket or something that's not going through the network stack, but I can't confirm that or anything.
I guess I'm just hoping some people here might know enough to point me in the right direction or tell me I'm already headed there. The project I'm working on is a multiplayer game server designed to work "out of the box" with a multiplayer game client both powering their 3D graphics/calculations with Three.js. The client and server will be made open source to everyone once I get them all working to my satisfaction, and I want to make sure that the architecture is as scalable as possible so people don't build a game on this and then go to scale up and end up hitting a wall.
Anyway thanks for your time if you actually read all this :) | I think that 0MQ would be a very good choice, but I admit that I don't know the others :D
For 0MQ it's transparent what transport you decide to use, the library calls are the same. It's just about choosing particular endpoint (and thus transport) during the call to 'zmq_bind' and 'zmq_connect' at the beginning. There are basically 4 paths you may decide to take:
1. "inproc://<id>" - in-process communication endpoint between threads via memory
2. "ipc://<filepath>" - system-dependent inter-process communication endpoint
3. "tcp://<ip-address>" - clear
4. "pgm://..." or "epgm://..." - an endpoint for Pragmatic Reliable Multicast
So to put is simply, the higher in the list you are, the faster it is and the less problems considering latency and reliability you have to face. So you should try to keep as high as possible. Since your components are processes, you should go with the IPC transport, naturally. If you later on need to change something, you can just change the endpoint definition and you are fine.
Now what is in fact more important than the transport you choose is the socket type, or rather pattern you decide to use. You situation is a typical request-response kind of communication, so you can either do
1. Manager: REP socket, Threads: REQ socket; or
2. Manager: ROUTER, Threads: REQ or DEALER
The Threads would then connect their sockets to the single Manager socket assigned to them and that's all, they can start to send their requests and wait for responses. All they have to decide on is the path they use as the endpoint.
But to describe in details what all those socket types and patterns mean is definitely out of the scope of this post, but you can and should read more about it in the <URL>
Hope it helped a bit, cheers! | |

THanks all | |
12,202,673 | 1 | 12,206,227 | I'm totally new to this liquid layout stuff. I've notice, as most of us, that while most of my layout components "liquify", images, unfortunately, don't.
So I'm trying to use the 'max-width: 100%' on images as suggested on several places.
However, and despite the definition of 'max-width' and 'min-height' of the img , the don't scale.
If you see it on a wide resolution, you would notice that the "kid image", for example, don't scale.
Any clue about what could the issue be, why does that image not scale?
Browsers: /
IOS:
Resolution:
I get an image that doesn't scale until the end of it's container.
The img width won't fit the 'article' element that contains it.
<IMAGE>
I expect the image to enlarge, until it reaches the end it's container.
Visually, I'm expecting the image to be as wide as the paragraph immediately below, in a way that, the right side of the image stays vertically aligned with the right side of the paragraph below. | I think you misunderstand what 'max-width' does.
'max-width:100%' means "the maximum width this element can be is 100% of it's container". Anything that's naturally smaller will not be affected. That's what you have now and it's working properly. If you used 'max-width:800px', it would mean "never let this image be more than 800px wide", it wouldn't force an 800px width, that's what 'width' is for.
'width:100%' means "this element should always be 100% width of it's container". Anything that would normally be smaller must now take up the entire width. Anything bigger will shrink to the container's width.
For your case, just use 'width:100%' and size your actual images to fit the actual maximum (and pick a reasonable maximum width for the container). Images usually look better when scaled down than scaled up, but when optimizing for mobile devices you might want to do the opposite.
The reason you usually see 'max-width:100%' as a default style is so images don't extend beyond their containers and break the layout, since images are usually sized naturally by their actual width. | |
1,889,701 | 1 | 2,194,233 | I'm having a hard time even phrasing this question.
I'm displaying preview images to users in my UI within a ListBox. When a user hovers over the image, I'd like to expand it so the user can see more detail.
I've gotten to the point where I can "pop up" the image, but of course it is still within its normal position in the layout, meaning that rather than the image being displayed on top of the other controls near it, it only appears on top of the controls rendered before it and underneath those rendered after it. It is also being cropped by the bounds of the ListBox.
Is there a simple (i.e., no custom control development) way to, temporarily, remove that image from the visual layout and put it above all other elements?
Here's a crappy demo app that shows what I'm talking about:
<IMAGE>
Notice the zoomed image is clipped by the bounds of the ListBox (outside of the list box is red). Also, notice that UI elements rendered after the zoomed image overlay it still--both icons that come later and item names ("Item 5" and others seen in the lower left hand corner). | The solution which worked best for me was using the Popup primitive. It doesn't provide much in the way of control when it comes to animation (it comes with stock animations) but you can animate its contents any which way you like.

In this snippet, the popup is not open until 'IsMouseOver' is true for its Image (named "icon"). When the mouse enters the image, two things happen. The Popup opens (at 640x640) and an image is shown (48px by 48px). This image has a scale transform on it. The "icon" Image also has a storyboard for MouseEnter and MouseLeave. This storyboard uses a double animation, targeted at the popup image's ScaleTransform. This storyboard enlarges the image when the mouse enters and shrinks it when it leaves with a nice easing function.
The use case would be: "User is presented a listbox with small images for each item in the list. When the user hovers over the small image (icon), it springs forward and enlarges, giving the user a better view of the image. When the mouse leaves the image, it shrinks back to its original size." | |

<IMAGE> | The easiest way to get your page to render in Edge mode is to include a DOCTYPE on the top of your HTML page:
'''
<!DOCTYPE html>
'''
If you are testing your page locally or on the intranet, you may have to change your Compatibility view settings. These can be found in:
'''
"Tools" (Alt+T) -> "Compatibility View Settings" -> And uncheck "Display Intranet Sites in Compatibility View"
'''
You can also include the X-UA-Compatible tag, which will force the page to EDGE mode.

27,726,180 | 1 | 27,761,700 | For this example, I'm trying to build a system that will allow output from multiple sources, but these sources are not yet built. The output "module" will be one component, and each source will be its own component to be built and expanded upon later.
Here's an example I designed in MySQLWorkbench:
<IMAGE>
The goal is to make my output module display data from the output table while being easily expanded upon later as more sources are built. I also want to minimize schema updates when adding new sources. Currently, I will have to add a new table per source, then add a foreign key to the output table.
Is there a better way to do this? I don't know how I feel about these NULL-able foreign keys because the JOIN query will contains IFNULL's and will get unruly quickly.
Thoughts?
I will be displaying a grid using data in the output table. The output table will contain general data for all items in the grid and will basically act as an aggregator for the output_source_X tables:
'''
output(id, when_added, is_approved, when_approved, sort_order, ...)
'''
The output_source_X tables will contain additional data specific to a source. For example, let's say one of the output source tables is for Facebook posts, so this table will contain columns specific to the Facebook API:
'''
output_source_facebook(id, from, message, place, updated_time, ...)
'''
Another may be Twitter, so the columns are specific for Twitter:
'''
output_source_twitter(id, coordinates, favorited, truncated, text, ...)
'''
A third output source table could be Instagram, so the output_source_instagram table will contain columns specific to Instagram.
There will be a one-to-one foreign key relationship with the output table and ONLY ONE of the output_source_X tables, depending on if the output item is a Facebook, Twitter, Instagram, etc... post, hence the NULL-able foreign keys.
'''
output table
------------
foreign key (source_id_facebook) references output_source_facebook(id)
foreign key (source_id_twitter) references output_source_twitter(id)
foreign key (source_id_instagram) references output_source_instagram(id)
'''
I guess my concern is that this is not as modular as I'd like it to be because I'd like to add other sources as well without having to update the schema much. Currently, this requires me to join output_source_X on the output table using whatever foreign key is not null. | This design in almost certainly bad in a few ways.
It's not that clear what your design is representing but a straightforward one would be something like:
'''
// source [id] has ...
source(id,message,...)
// output [id] is approved when [approved]=1 and ...
output(id,approved,...)
// output [output_id] has [source_id] as a source
output_source(output_id,source_id)
foreign key (source_id) references source(id)
foreign key (source_id) references source(id)
'''
Maybe you have different subtypes of outputs and/or sources? Based on sources and/or outputs? Maybe each source is restricted to feeding particular outputs? Are "outputs" and "sources" actually of outputs and sources, and this is info not on how outputs are sourced but info on what kinds of output-source pairings are permittted?
Please give us statements parameterized by column names for the basic statements you want to make about your application. Ie for the application relationships you are interested in. (Eg like the code comments above.) (You could do it for the diagrammed design but probably that would be overly complicated and not really reflecting what you are trying to model.)
Re your EDIT:
> There will be a one-to-one foreign key relationship with the output
table and ONLY ONE of the output_source_X tables, depending on if the
output item is a Facebook, Twitter, Instagram, etc... post, hence the
NULL-able foreign keys.
You have a case of multiple disjoint subtypes of a supertype.
Your situation is a lot like that of <URL>.
> Please give us statements parameterized by column names for the basic
statements you want to make about your application
and you will find straightforward statements (as above). And if you give the statements for your current design you will find them complex. See also this.
> I guess my concern is that this is not as modular as I'd like it to be
because I'd like to add other sources as well without having to update
the schema much.
Your structure is not reducing schema changes compared to proper subtype designs.
Anyway, DDL is there for that. You can genericize subtypes to avoid DDL only by loss of the DBMS managing integrity. That would be relevant or reasonable based on evaluating DDL vs DML performance tradeoffs. Search re (usually, anti-pattern) EAV.
( after you shown that creating & deleting new tables is infeasible and the corresponding horrible integrity-&-concurrency-challenged mega-joining table-and-metadata-encoded-in-table EAV information-equivalent design is feasible should you consider using EAV.) | |

I've tried printing the positions before the scrolling, when it ends, and when it gets initiated again.
Results are that the background move positions, and once you try to move it again it starts at those new Coordinates, the screen has just itself over the centre of the sprite.
<IMAGE> | I'm not sure I 100% understand the situation you are describing, but I believe that it might be related to the anchor point of your background sprite node.
in your method:
'''
- (void)translateMotion:(UIGestureRecognizer *)recognizer Translation:(CGPoint)translation
'''
you have the line:
'''
self.selectedNode.position = location;
'''
Since your background sprite's anchor point is set to its center by default, any time you move a new touch, it will snap the background sprite's center to the location of your finger.
In other words, 'background.sprite.position' sets the coordinates for the background sprite's (which by default is the center of the sprite), and in this case any time you set a new position, it is moving the center to that position.
The solution in this case would be to shift the anchor point of the background sprite to be directly under the touch each time, so you are changing the position of the background relative to the point of the background the touch started on.
It's a little hard to explain, so here's some sample code to show you:
1) Create a new project in Xcode using the Sprite Kit Game template
2) Replace the contents of GameScene.m with the following:
'''
#import "GameScene.h"
@interface GameScene ()
@property (nonatomic, strong) SKSpriteNode *sprite;
@end
@implementation GameScene
-(void)didMoveToView:(SKView *)view {
/* Setup your scene here */
self.sprite = [SKSpriteNode spriteNodeWithImageNamed:@"Spaceship"];
self.sprite.position = CGPointMake(CGRectGetMidX(self.frame),
CGRectGetMidY(self.frame));
[self addChild:self.sprite];
}
-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
/* Called when a touch begins */
UITouch *touch = [touches anyObject];
CGPoint nodelocation = [touch locationInNode:self.sprite];
//[self adjustAnchorPointForSprite:self.sprite toLocation:nodelocation];
CGPoint location = [touch locationInNode:self];
self.sprite.position = location;
}
-(void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event {
UITouch *touch = [touches anyObject];
CGPoint location = [touch locationInNode:self];
self.sprite.position = location;
}
-(void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event {
}
-(void)adjustAnchorPointForSprite:(SKSpriteNode *)sprite toLocation:(CGPoint)location {
// Remember the sprite's current position
CGPoint originalPosition = sprite.position;
// Convert the coordinates of the passed-in location to be relative to the bottom left of the sprite (instead of its current anchor point)
CGPoint adjustedNodeLocation = CGPointMake(sprite.anchorPoint.x * sprite.size.width + location.x, sprite.anchorPoint.y * sprite.size.height + location.y);
// Move the anchor point of the sprite to match the passed-in location
sprite.anchorPoint = CGPointMake(adjustedNodeLocation.x / self.sprite.size.width, adjustedNodeLocation.y / self.sprite.size.height);
// Undo any change of position caused by moving the anchor point
self.sprite.position = CGPointMake(sprite.position.x - (sprite.position.x - originalPosition.x), sprite.position.y - (sprite.position.y - originalPosition.y));
}
-(void)update:(CFTimeInterval)currentTime {
/* Called before each frame is rendered */
}
@end
'''
3) Run the project in the sim or on a device and click / touch the top tip of the space ship and start dragging.
4) Notice that the spaceship snaps its center point to where your touch is. If you drag and release it to a new location, and the touch the screen again, it snaps its center back to your finger.
5) Now uncomment the line:
'''
[self adjustAnchorPointForSprite:self.sprite toLocation:nodelocation];
'''
and run the project again.
6) See how you can now drag the ship where you want it, and when you touch it later, it stays in place and follows your finger from the point you touched it. This is because the anchor point is now being adjusted to the point under the touch each time a new touch begins.
Hopefully this gives you a solution you can use in your game as well. | |

'''

Being an array formula it needs to be confirmed with Ctrl-Shift-Enter instead of enter when exiting edit mode. If done correctly then Excel will put '{}' around the formula.

67,546,438 | 1 | 67,546,558 | I wrote a .DLL library with a very simple extension method for 'string'.
My method - '.Remove(char deletedChar)', removes all occurrences of a 'char' in a 'string'. This overloads the default '.Remove(int startIndex)' method. However, when I want to use it, '.Remove(int startIndex)' is invoked, instead of my method, despite me giving 'char' as the argument.
What I mean is, given this code:
'''
string Test = "12-34-56-78-90-123-<PHONE>-89012-34567-890123-456789-000000";
MessageBox.Show(Test.Remove('-'));
'''
My expected result is:
'''
1234567890123456789012345678901234567890123456789000000
'''
However, the actual result is:
'''
12-34-56-78-90-123-<PHONE>-89012-34
'''
Check it out on the screenshot:
<IMAGE>
This means, that my 'char '-'' is interpreted as its ASCII value (45), and this is the start index for removal of the string.
Why does this happen? Even casting 'char' to a 'char' (i.e. '(char)'-'') does not fix it. I know I can simply rename the extension method, but I still cannot understand why does this happen. Could someone explain this phenomenon or point to a doc that explains it?
Pasting my extension method in case someone will want to use it:
'''
/// <summary>
/// Removes all occurences of specified char.
/// </summary>
/// <param name="str"></param>
/// <param name="deletedChar">The char you want to remove.</param>
/// <returns>string without the specified char.</returns>
public static string Remove(this string str, char deletedChar)
{
for (int i = 0; i < str.Length; i++)
{
if (str[i] == deletedChar)
{
str = str.Remove(i, 1);
i--;
}
}
return str;
}
''' | C# instances methods are called before extensions if found.
From the <URL>:
> When the compiler can't find an instance method with a matching signature, it will bind to a matching extension method if one exists.
Writing this helper class, we can see that the good method is called:
'''
public static class StringHelper
{
public static string MyRemove(this string str, int index)
{
return "remove at index";
}
public static string MyRemove(this string str, char code)
{
return "remove all chars";
}
}
'''
'''
Console.WriteLine("".MyRemove(1));
Console.WriteLine("".MyRemove('a'));
'''
'''
remove at index
remove all chars
'''
Thus the solution is to use a dedicated method's name:
'''
public static class StringHelper
{
public static string RemoveAll(this string str, char deletedChar)
{
for ( int i = 0; i < str.Length; i++ )
{
if ( str[i] == deletedChar )
{
str = str.Remove(i, 1);
i--;
}
}
return str;
}
}
'''
Therefore the design and the usage is more clear and clean, as well as more more speaking while the type of the parameter tells what to remove.
But such a method is not optimized and can for example be replaced by:
'''
public static string RemoveAll(this string str, char code)
{
return str.Replace(code.ToString(), "");
}
'''
Or by this one which is better:
'''
using System.Text;
public static string RemoveAll(this string str, char code)
{
var builder = new StringBuilder();
foreach ( char c in str )
if ( c != code )
builder.Append(c);
return builder.ToString();
}
'''
Or using Linq, but probably less optimized than the previous:
'''
using System.Linq;
public static string RemoveAll(this string str, char code)
{
return new string(str.Where(c => c != code).ToArray());
}

9,299,386 | 1 | 9,299,573 | Recently, after some discussions, I decided to use List for social buttons such as Google+, Facebook-like and twitter-follow. Example (under Follow us Section):

Simply - is it right to use form inside '<li>' as shown in the example above?

51,200,054 | 1 | 51,200,713 | PowerShell gives me this output back when running a command:
<IMAGE>
I'm having trouble trying to split it, because it's not tab-separated, is space-separated, therefore when i use '.split("")' the column 'Module-Type' is being separated incorrectly because its content also has spaces.
I'm new at this, any help would be appreciated.
Here's my code:
'''
$RS = .\Plink server@puttysession -pw "password" "command"
foreach ($RSln in $RS){
$arr = $RSln.split('',[System.StringSplitOptions]::RemoveEmptyEntries)
Write-Host $RSln "|" $arr.Length
}
'''
This gives me the line and the length of the created array, the first two lines are arrays with 5 as length, the third and fourth have 9 items because of the spaces in 'ModuleType' | The recommended way of handling this kind of input in PowerShell is to parse it into custom objects. You can do that either with a regular expression:
'''
$RS | Where-Object {
$_ -match '(\d+)\s+(\d+)\s+(.*?)\s+([a-z]+(?:-[a-z0-9]+){2,})\s+(.*)'
} | ForEach-Object {
New-Object -Type PSObject -Property @{
'Mod' = [int]$matches[1]
'Ports' = [int]$matches[2]
'ModuleType' = $matches[3]
'Model' = $matches[4]
'Status' = $matches[5]
}
}
'''
or (if the columns are of fixed width) by extracting substrings at defined offsets:
'''
$RS | Select-Object -Skip 2 | ForEach-Object {
New-Object -Type PSObject -Property @{
'Mod' = [int]$_.Substring(0, 3).Trim()
'Ports' = [int]$_.Substring(5, 5).Trim()
'ModuleType' = $_.Substring(12, 35).Trim()
'Model' = $_.Substring(48, 18).Trim()
'Status' = $_.Substring(67).Trim()
}
}
'''
The 'Select-Object -Skip 2' is needed to skip over the 2 header lines.
If all columns were separated by more than one space splitting via '-split '\s\s+'' (split at 2 or more consecutive whitespace characters) would work too. However, with your data that is not the case, since at least the first 2 data rows have only a single space between the 3rd and 4th column. | |

48,428,766 | 1 | 48,435,580 | I have a text file filled with several lines of data, and I would like to split it into 5 different elements like so..
<IMAGE>
I am successfully reading in the data and putting it into an array. Now I would like to split each part of the text up into different lists so I can compare the data against one another.
I have currently managed to read in the first 4 elements of each line into their relevant lists but the 5th one is throwing me the error "System.IndexOutOfRangeException" which I can only assume is because the first line it reads in has no value for the 5th element?
So my question is, is there a way to populate null values when writing them to a number of lists?
I've tried manually assigning the size of the array and lists but I still get the same error.
Here is my code:
'''
class Program
{
static void Main(string[] args)
{
// Reading in file containing data from BT Code Evaluation sheet (for testing purposes).
// Each line gets stored into a string array, each element is one line of the data.txt file.
//String[] lines = System.IO.File.ReadAllLines(@"C:\Users\Ad\Desktop\data.txt");
String[] lines = new String[5] {"monitorTime", "localTime", "actor", "action", "actor2"};
lines = System.IO.File.ReadAllLines(@"C:\Users\Ad\Desktop\data.txt");
char delimiter = ' ';
List<String> monitorTime = new List<String>();
List<String> localTime = new List<String>();
List<String> actor = new List<String>();
List<String> action = new List<String>();
List<String> actor2 = new List<String>();
// Foreach loop displays the lines of text in the data file.
foreach (String line in lines)
{
// Writes the data to the console.
Console.WriteLine(line);
String[] data = new String[5] { "monitorTime", "localTime", "actor", "action", "actor2" };
data = line.Split(delimiter);
monitorTime.Add(data[0]);
localTime.Add(data[1]);
actor.Add(data[2]);
action.Add(data[3]);
actor2.Add(data[4]);
}
foreach (String time in monitorTime)
{
Console.WriteLine(time);
}
foreach (String time in localTime)
{
Console.WriteLine(time);
}
foreach (String name in actor)
{
Console.WriteLine(name);
}
foreach (String actions in action)
{
Console.WriteLine(actions);
}
foreach (String name in actor2)
{
if (name != null)
{
Console.WriteLine("UNKNOWN");
}
else
{
Console.WriteLine(actor2);
}
}
// Creates an empty line between the data and the following text.
Console.WriteLine("");
// Displays message in console.
Console.WriteLine("Press any key to analyse data and create report...");
Console.ReadKey();
}
}
''' | You need to check the bounds of you array before you try to add. If their aren't enough items you can add null instead.
For example:
'''
actor2.Add(data.length > 4 ? data[4] : null)
'''
(Note: You could do the same type of check on the other items as well, unless you are positive that the last item is the only one that might be null)
This is using the <URL>, but you could also use a simple 'if/else', but it'll be more verbose. It's equivalent to:
'''
if (data.length > 4)
{
actor2.Add(data[4]);
}
else
{
actor2.Add(null);
}
'''
This along with 'Console.WriteLine(name);' instead of 'Console.WriteLine(actor2);' should fix you immediate problem.
However, a much better design here would be to have a single list of objects with 'MonitorTime', 'LocalTime', 'Actor', 'Action' and 'Actor2' properties. That way you don't ever have to worry that the 5 parallel arrays might get out of sync.
For example, create a class like this:
'''
public class DataItem
{
public string MonitorTime { get; set; }
public string LocalTime { get; set; }
public string Actor { get; set; }
public string Action { get; set; }
public string Actor2 { get; set; }
}
'''
Then instead of your 5 'List<String>', you have one 'List<DataItem>':
'''
List<DataItem> dataList = new List<DataItem>();
'''
Then in your loop to populate it you'd do something like:
'''
data = line.Split(delimiter);
dataList.Add(new DataItem()
{
MonitorTime = data[0],
LocalTime = data[1],
Actor = data[2],
Action = data[3],
Actor2 = data.length > 4 ? data[4] : null
});
'''
Then you can access them later with something like:
'''
foreach (var item in dataList)
{
Console.WriteLine(item.MonitorTime);
//...
}

5,912,013 | 1 | 5,927,178 | I am writing a backend surveys database. The database is the backend for multiple applications that are used for gathering survey type data. I have a schema that includes a table that designates the application and what questions belong to that application.

each application has 1 or more users
each user may have 1 role in the application they have access to

app1 has 15 users 1 user is admin
app1 has 2 roles defined for user access
app2 has 30 users admin user from app1 has access but is regular user

app2 has 4 roles defined for user access.

Application ->ApplicationUsers<-Users

What would be the correct way to make this work? | Let's assume that this
> each user may have 1 role in the

different roles in each application.
should be punctuated like this.
> Each user may have 1 role in the
application they have access to, each
role may exist in 1 or more
applications, each user may have
different roles in each application.
If that first clause means that each user have one and no more than one role in each application they have access to, then your schema won't work. The compound primary key {ApplicationId, UserID, RoleID} in ApplicationUserRoles allows multiple roles per user.
To limit the constraint "one row (and one role) per user per application", the primary key for ApplicationUserRoles should be just {ApplicationID, UserID}.
Also, if UserID is unique in the table Users, it should probably be the primary key, and you should probably drop the column "ID" from that table. | |

appear under each other with spacing. To get the text in the boxes I used '<style>' in '<head>'.
How can I FIX this annoying problem?

18,452,449 | 1 | 18,452,523 | Here's a picture so you can understand what I want:
<IMAGE>
I have this green element already set up in my relative layout, and what I want is to put another element (the black one in the pic) above it so it gets centered exactly in the middle of the green element.
Keep in mind that the black element doesn't have a constant width, and it's bigger in width than the green one.
There are stuff like android:layout_alignLeft and android:layout_alignRight which would be helpful if I wanted it aligned left or right, but as far as I know there is no android:layout_alignCenter so I don't know how to do this thing... | As you said yourself, put both elements inside a .
Then, set the "" property of both elements to true, and then set the "" property of the green element to the id of the black element.
Here is the complete example:
'''
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<View
android:id="@+id/view1"
android:layout_width="100dp"
android:layout_height="40dp"
android:background="@color/Black"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true" />
<View
android:id="@+id/view2"
android:layout_height="100dp"
android:layout_below="@+id/view1"
android:background="@color/Green"
android:layout_centerHorizontal="true" />
</RelativeLayout>
'''
("center_vertical" is kinda optional)
Or here,
'''
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

<View
android:id="@+id/view1"

android:layout_alignRight="@+id/view1"
android:layout_marginLeft="30dp"

You can hide 'tableView''s standard separator line, and add your custom line at the top of each cell. The easiest way to add custom separator is to add simple 'UIView' of 1px height:
'''
UIView* separatorLineView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, cell.bounds.size.width, 1)];
separatorLineView.backgroundColor = [UIColor grayColor];
[cell.contentView addSubview:separatorLineView];

I'm working on an uni assignment where I need to build a small student registration program.
I need to create a 7 digit student number whenever a user clicks register, my code and validation and connection to DB is working fine,
1. The student number should have 7 digits
2. The first two digits represent the year the student registers in (the last two digits of the full year) Which I get like this and it works fine: Dim cyear = DateTime.Now.ToString("yy")
3. Here is my problem: the next 4 numbers represents the number of students who have registered thus far, this number is always padded with 0 from the left to make up four digits.
---
if 20 students have registered thus far (in 2014) then the next student will
have student number 140021
---
4 The last digit is a check digit which you get by summing the first 6 individual numbers of the student number, divide the result by 10 and take the remainder, and subtract the remainder by 10 to get last digit. , but what if only one student has registered thus far? Surely that cant produce a correct result
(See Number 3 above) How do I generate numbers 3 to 6, padding from left to right incrementing with one with each new registration?
I tried the following code but it is far off from working
'''
'Generate Student NR'
Dim newstudent As Integer
'displays 1st 2 letter of current year for student number'
Dim cyear = DateTime.Now.ToString("yy")
Dim lastdigit As Double
Dim lastdigitRemainder
Dim studentnr As Integer
'if statment to generate new student number for each registration'
If (register.Enabled = True) Then
newstudent = cyear + 0 + 0 + 0 + 1
'generate last digit of student nr'
lastdigit = (cyear + newstudent) / 10
lastdigitRemainder = lastdigit - 10
studentnr = lastdigit + lastdigitRemainder
MsgBox(studentnr)
'''

74,874,445 | 1 | 74,891,068 | I have a state machine diagram for an application that has a UI and a thread that runs parallel. I model this using a state with 2 parallel regions. Now I want when that thread gives some message, for example an error, that the state of the UI changes, for example to an error screen state.
I was wondering what the correct method to do this is, as I was not able to find any example of this situation online.
The options that I thought of were creating a transition from every state to this error state when the error state is called, which in a big diagram would mean a lot of transitions. Or by just creating a transition from the thread to the error state (As shown in the image), which could possible be unclear.
Example of second option
<IMAGE> | You don't need a transition from every state. Just use a transition from the State 'State' to the 'Error window' state. It will then fire no matter what states are currently active.
Such a transition will also leave the 'Some process' state. Since you didn't define initial states in the orthogonal regions, the right region of the state machine will then be in an undefined state. Some people allow this to happen, but for me it is not good practice. So, I suggest to add initial states to both regions. Then it is clear, which sub state will become active, when the 'State' state is entered for any reason. The fork would also not be necessary then.
How you have done it in your example would also be Ok. However, since the 'Some process' state is left by this transition, this region is now in an undefined state. Again, the solution to this is to have an initial state here. I would only use such a transition between regions, when it contains more than one state and the 'On error' event shall not trigger a transition in all of the states.
If the 'Some process' state is only there to allow for concurrent execution, there is an easier way to achieve this: The 'State' state can have a do behavior, that is running while the sub states are active. Orthogonal regions should be used wisely, since they add a lot complexity. | |

1. How can I remove the file or folder I am in from the list? For example, if I am on the page index.php, it is still appearing on the list.
2. I want to sort files by given them a number example '1file.php' '2anotherfile.php'.. How could I sort them by the number, then remove the number and '.php', and finally print it out?
If you feel like refactoring something please do so...
<IMAGE> | 1. "How can I remove the file or folder I am in from the list? For example, if I am on the page index.php, it is still appearing on the list."
Just check if the current item is the current file, if it is then skip it:

else {
if ($name == basename(dirname(__FILE__))) continue; // if this is the current file, go to the next iteration of the loop
$name = explode('.php',$file);

Note that this assumes you are in the same directory as the file (which it can do because '$dir' is always the directory the script is in), if not you can just add a directory check as well.
1. "How can add a number to the start of the file or folder, example 1index.php, then on the code, organize all the files and folder by number, and print them without the number and '.php'?"

Thanks,
<IMAGE> | The problem seems to be associated with Autolayout.
Please select the date picker in storyboard and add "Center Horizontly in container" constraint with UITableViewCell's content view. See the attached image for better understanding.

To add constraint, right click on the UIDatePicker while holding and drag the pointer to UITableViewCell's content view and release the pointer. Now select the "Center Horizontly in container" constraint.

23,696,138 | 1 | 23,697,021 | Can I join one system with component of second subsystem by dependency ?
My intence is to show that in my system(system 2) is module / component called subsystem 1 and external system uses this subsystem.
<IMAGE>
Is this correct? Interfaces aren't defined now, so I can only show that dependency. | Let me interpret this diagram and the answer should come naturally. :)
"System 1" depends on "Subsystem 1" in some way. "System 1" does not know anything about the "System 2", that contains the "Subsystem 1". This means that "System 1" somehow gets the direct access to "Subsystem 1", with no contact with "System 2".
Is this correct?

26,504,593 | 1 | 26,506,868 | I have a project for my C# module where I want to make a booking system for the AULA(see picture below).

Is it possible for me to rotate components in any degrees I choose or is there a better way for me to do this?
<IMAGE> | I have been using this <URL> in the past. You just need to provide the background image and a collection of polygons representing clickable areas.

26,535,258 | 1 | 26,535,606 | Is there a way to trim letters of a string? Or Convert a string to an integer removing its letters from it?
Story:
I have in which I have bunch of options on an application and all of them add up points depending on the option selected by the user. I gave them values like hsq2 hsq4 hsq6 and now I need to be able to get the one that is selected and remove letters from it and add up values. If you know a better way of doing this please let me know also..
<IMAGE> | The better way would be to use 'XAML' and databinding to a rich ViewModel that has separate properties for each item's label and its score value as an integer. Then a method on your ViewModel would perform the sum of selected values and return it for data binding to the Total Score display. Search for MVVM if you want to know more about that approach.
However, since it looks like you're building a WinForms app, you could use the Tag property of each element to store the integer value. That's how I would have done it 7 years ago. | |
8,854,388 | 1 | 8,855,678 | I have basic knowledge of CSS.
Using overflow isnt really ideal. Scroll bars are specific to the div, rather than the browser. So displaying on phones is a problem.(especially the iPhone which disables the scroll leaving content unaccessable).
Having overflow on visible is shown in the image, and obviously hidden isnt what i want.
So, is it possible to have the main div (white area) expand to contain the div rather than cause an overflow. The white part currently stops on the screen edge (before scrolling)
Take Stackoverflow for example. Its centered. and only when you cant contain it, does it go offscreen. But u simply scroll right to see the rest. I would much prefer mine centred too.
if anyone has an knowledge of how to achieve this, please let me know. The basic concept at the moment is
'''
<div id="main">
<div id="sidebar"></div>
<div id="body"></div>
</div>
'''
<IMAGE>
This is ASP.NET MVC 3 | This is indeed quite tricky to achieve because there is no CSS way to resize parent elements according to their children's content, and also in JavaScript it's not straight-forward.
There is a solution though with jQuery using <URL>. Basically the mini-script creates a span around your text and measures its width. You can then use it to resize your container:
'''
<script type="text/javascript">
$(function() {
//define the mini-function to measure text
$.fn.textWidth = function(){
var html_org = $(this).html();
var html_calc = '<span>' + html_org + '</span>'
$(this).html(html_calc);
var width = $(this).find('span:first').width();
$(this).html(html_org);
return width;
};
//now resize your main container according to the body width.
$("#main").css("width", $("#body").textWidth());
//this would be body + sidebar
// $("#main").css("width", $("#body").textWidth()+$("#sidebar").textWidth());
});
</script>

6,348,992 | 1 | 6,350,961 | In Excel, if you import whitespace delineated text in which the columns do not line up perfectly and data may be missing, like
'''

CYS-I0014_ >14.0 0.00
LYS+I0013_ 11.827 0.781 0.440 0.18
'''
you are given the option to treat it as fixed width columns, and Excel can figure out the column widths automatically, usually with pretty good results. Is there a library in Python which can break up poorly formated fixed-width text in a similarly automatic fashion?
This is what the fixed width text import looks like in Excel. In step one, you just check the 'fixed-width' radio button, and then here in step two Excel has already added in column breaks automatically. The only time it fails to do so properly is when there is not at least one whitespace character overlapping in each column break in each line.
<IMAGE> | First off, Excel (2003, at home) isn't quite so smart. If your column 1000*chi2 contains spaces, e.g. 1000 * chi2, excel will guess wrong.
Trivial case: if your data was originally separated by tabs (not spaces), and multiple tabs were used to indicate empty columns, then, at least in TCL, it's easy to split each line by tab content, and I guess trivial too in Python.
But I'm guessing your problem is that they've used space characters only.
The biggest clue I see to solving this one was to paste your text into notepad and choose a fixed size font. Everything lines up neatly, and you can use the number of characters in each line as a measure of "length".
So, IF you can rely on this feature of your input, then you can use a "sieve" approach to identifying where the column breaks are automatically. As you munch through the lines in a first pass, note the "positions" along the line that are occupied by non white-space, eliminating a position from your list if it's EVER occupied by non white space. As you go, you'll quickly arrive at a set of positions that are NEVER occupied by non white space. These, then, are your column dividers. In your example, your "sieve" would end up with positions 10-16, 23-24,32, 42-47 never occupied by non whitespace (assuming I can count).
Thus the complement of that set is your set of column positions in which your data must lie.
So, foreach line, each block of nonwhitespace will fit into exacly one of your columns from the set of positions (i.e the complement set) identified above.
I've never coded in Python, so attached is a TCL script that will identify,using the sieve approach, where the column breaks are in the text, and emit a new text file with exactly those space characters replaced by a single tab - ie. 10-16 replaced by one tab, 23-24 by another, etc.
The resulting file is tab-separated, i.e. the trivial case. I confess I've only tried it on YOUR little case data, copied into a text file called ex.txt; output goes to ex_.txt. I suspect it also might have problems if headings contain spaces.
Hope this helps!
'''

Credit memo does not support the linked txn details yet, so as a workaround, you can try this-

9,139,386 | 1 | 10,139,720 | Which will scale best for performance, file-size, (and my sanity): Animated '.gif's or a spritesheet with animations using CSS (and JS when need be)?
### Filesize
So, I'm honestly not sure which will be better here since I don't understand the compression of frames in '.gif'. My guess would be that they would end up about equal if I can swing it right, but if this is wrong, or if this is a factor for a different reason let me know.
The main advantage here, in my mind, goes to Spritesheets as I would be able to include multiple animations on a single sheet (and we're talking hundreds of animated sprites here). And based on <URL>'. Where as with a '.gif' file I really can only include one animation since each will likely have a different duration.
Also, some of the animations repeat for a given sprite, so the spritesheet would only have to have one copy of the frames, where as a '.gif' would need to have all the frames (at least to my knowledge).
### Performance
Guessing here again, my intuition tells me that animated '.gif's are going to be significantly faster as I won't have to manage all the animations at the same time I'm doing a lot of JS code for other things. But, I don't know for sure, maybe browsers take a significant hit with 30+ animated '.gif's.
### My Sanity
The spritesheets are made for me, so my work would be high in the beginning (writing and animation engine and hand coding one/each sheet). But once written, it is usable for good and a change in a spritesheet requires minimal changes to code.
On the other hand, animated '.gif' files are not a cake to make in Photoshop (if you have a better program, let me know). And each one must be hand made and is a long process. But, once they are made, I don't really have to change them. My spritesheets aren't likely to change very quickly, so chances are it will be a one and done.
### My Question (tl;dr)
Which is going to scale better to the hundreds of animations in terms of filesize (including HTTP header transfer as it will go over the web), performance in modern browsers, and ease of creation (lowest priority, but if you can make my job easier, or argue to this, I would be grateful), Animated '.gif' files built from spritesheets, or simply using CSS and the spritesheets I already have?

<p><a ng-href="http://twitter.com/intent/favorite?tweet_id={{ tweet.id }}">Favorite</a></p>

For each tweet that is on the page, the proper HTML is generated. In the case that the tweet has the id 431111460186759200, the following html is generated for these links:
'''

If you try with the id 431216327143858177 it works fine: <URL>.
If the tweet your code is referencing still exists, try using tweet.id_str instead of tweet.id. For example Javascript can't handle numbers as big as tweet ids so for example 431216327143858177 becomes 431216327143858200. Using id_str you would be sure it works in any language.

16,056,778 | 1 | 16,192,164 | I am working on integrating Twitter in an app and while all works as it should I am stumped on the 'setOnItemClickListener()' not triggering when a 'ListView' 'item' has a link in it. It works just fine when an 'item' does not have a link (URL) in it.
Clicking on the URL itself opens the web page in a Browser.
Please see the screenshots added as reference at the end of the post.
It is a custom 'ListView' that employs a 'BaseAdapter'. I am not sure which piece of code to put in but on being pointed to a code block that the folks here may need, I will add it immediately.
The idea behind needing to ignore the links (URLs) in an item is to provide a functionality that shows the tweet details when a user clicks on one. Something similar to what the Twitter Android app does.
So what do I do to make the 'setOnItemClickListener()' ignore the links in items?
Okay. SO I am not sure if it is relevant to the question, but, from a combination of a few solutions from SO which led me to the <URL> Open Source project, I have managed to get a few things working. But unfortunately, it doesn't address my primary question.
How do I make the 'setOnItemClickListener()' ignore the links in an item so I can click it and show the details in another Activity and yet, when I click on a link, not trigger the 'setOnItemClickListener()'? I keep getting partial solutions in every attempt I make. But at times, when I click on a 'link', the 'setOnItemClickListener()' triggers too.
This is how it the flow looks at the moment:
<IMAGE>
In the top two screenshots, it works as it should. Not clicking on a link after all.
In the bottom two, however, when I click on the link, it shows the Profile for the user (). This part is derived from the TweetLanes source. The problem is, the click listener is also triggered. This is one of the solutions I am trying out. In this case, I have commented out the 'setOnItemClickListener()' and am using a 'OnClickListener()' on the 'TextView'. This is the one method which has partial success so far. | You probably want to take a look at <URL>
He presents a TextView that issues this problem basically by introducing a different 'LinkMovementMethod':
'''
public static class LocalLinkMovementMethod extends LinkMovementMethod{
static LocalLinkMovementMethod sInstance;
public static LocalLinkMovementMethod getInstance() {
if (sInstance == null)
sInstance = new LocalLinkMovementMethod();
return sInstance;

@Override
public boolean onTouchEvent(TextView widget, Spannable buffer, MotionEvent event) {
int action = event.getAction();
if (action == MotionEvent.ACTION_UP ||
action == MotionEvent.ACTION_DOWN) {
int x = (int) event.getX();
int y = (int) event.getY();
x -= widget.getTotalPaddingLeft();
y -= widget.getTotalPaddingTop();
x += widget.getScrollX();
y += widget.getScrollY();
Layout layout = widget.getLayout();
int line = layout.getLineForVertical(y);
int off = layout.getOffsetForHorizontal(line, x);
ClickableSpan[] link = buffer.getSpans(off, off, ClickableSpan.class);
if (link.length != 0) {
if (action == MotionEvent.ACTION_UP) {
link[0].onClick(widget);
} else if (action == MotionEvent.ACTION_DOWN) {
Selection.setSelection(buffer,
buffer.getSpanStart(link[0]),
buffer.getSpanEnd(link[0]));
}
if (widget instanceof TextViewFixTouchConsume){
((TextViewFixTouchConsume) widget).linkHit = true;
}
return true;
} else {
Selection.removeSelection(buffer);
Touch.onTouchEvent(widget, buffer, event);
return false;
}
}
return Touch.onTouchEvent(widget, buffer, event);
}

Based on it, I advice you to fix the file 'TwitterLinkify.java' (the function that sets the link movement) like this:
'''
private static final void addLinkMovementMethod(TextView t) {
MovementMethod m = t.getMovementMethod();
if ((m == null) || !(m instanceof LocalLinkMovementMethod)) {
if (t.getLinksClickable()) {
t.setMovementMethod(LocalLinkMovementMethod.getInstance());
}
}
}

If you don't short-circuit with the null check, you'll end up calling a comparison of a null value ('m.DistrictId') against a non-null value ('districtId'). | |

19,060,378 | 1 | 19,236,295 | How to remove one specific selected file from input file control?
I have an input file control with the option to select multiple files; however, I want to validate a file and if it has an wrong extension then I should remove that file from the file control itself, is it possible?
I tried as below
'''
<input type="file" name="fileToUpload" id="fileToUpload" multiple/>
<script> $("#fileToUpload")[0].files[0] </script>
'''
Below is the screenshot of the object but I am not able to modify it
<IMAGE> | As other people pointed out, <URL> API.
Below is a round about way of completely avoiding needing to modify the 'FileList'.
Steps:
1. Add normal file input change event listener
2. Loop through each file from change event, filter for desired validation
3. Push valid files into separate array
4. Use FileReader API to read files locally
5. Submit valid, processed files to server
Event handler and basic file loop code:
'''
var validatedFiles = [];
$("#fileToUpload").on("change", function (event) {
var files = event.originalEvent.target.files;
files.forEach(function (file) {
if (file.name.matches(/something.txt/)) {
validatedFiles.push(file); // Simplest case
} else {
/* do something else */
}
});
});
'''
Below is a more complicated version of the file loop that shows how you can use the 'FileReader' API to load the file into the browser and optionally submit it to a server as a Base64 encoded blob.
'''
files.forEach(function (file) {
if (file.name.matches(/something.txt/)) { // You could also do more complicated validation after processing the file client side
var reader = new FileReader();
// Setup listener
reader.onload = (function (processedFile) {
return function (e) {
var fileData = { name : processedFile.name, fileData : e.target.result };
// Submit individual file to server
$.post("/your/url/here", fileData);
// or add to list to submit as group later
validatedFiles.push(fileData);
};
})(file);
// Process file
reader.readAsDataURL(file);
} else {
/* still do something else */
}
});
'''
A note of caution about using 'FileReader' API. Base64 encoding a file will increase its size by around 30%. If that isn't acceptable you will need to try something else. | |
16,821,197 | 1 | 16,821,430 | I'm trying to get Matlab to take this as a function of 'x_1' through 'x_n' and 'y_1' through 'y_n', where 'k_i' and 'r_i' are all constants.
<IMAGE>
So far my idea was to take 'n' from the user and make two 1xn vectors called 'x' and 'y', and for the 'x_i' just pull out 'x(i)'. But I don't know how to make an arbitrary sum in MATLAB.
I also need to get the gradient of this function, which I don't know how to do either. I was thinking maybe I could make a loop and add that to the function each time, but MATLAB doesn't like that. | I don't believe a loop is necessary for this calculation. MATLAB excels at vectorized operations, so would something like this work for you?

l = 10; % how large these vectors are

r = rand(l,1);
x = rand(l,1);
y = rand(l,1);

16,589,017 | 1 | 19,941,503 | I pinned 'Notepad2-mod' to the taskbar. When I click the pinned shortcut, it opens a new instance but doesn't stack in place. It begins a new stack. Additional clicks will utilize the second stack. This can probably best be explained via screenshot:
<IMAGE>
The oddest part is it used to stack on the taskbar shortcut if I started it by clicking on it or using WIN+num, but if I started 'Notepad2-mod' by right-clicking on a file and using "open with notepad2-mod" it would stack in a new stack. Now, they all stack in a new stack (not on the taskbar-pinned shortcut).
Both the "open with notepad2-mod" registry shortcut and the taskbar-pinned shortcut run the same executable.
Ultimately, I'd like them all to stack in the same place, on top of the taskbar-pinned icon.
'''
1) What did I do to persuade it to behave like this?
2) How can I convince it to all stack on the pinned icon?
'''
---
I just noticed in the Task Manager that when I double click a .txt file I'm running a version of this binary named 'Notepad2.exe' and when I click on the icon on the Taskbar I'm running a copy of this same binary named 'notepad.exe'. I must have done that to fool Windows 7 into thinking it was using vanilla Notepad. I thought changing this might fix it, but it did not. They still stack on a different portion of the Taskbar. They even respond to keyboard shortcuts like 'Start Button+Number' for the slot where they do actually stack. | Thanks to the <URL>, this issue is fixed. Go read his site for a better answer than mine, but, in case his site ever goes away, here are the relevant snippets:
> Notepad2 windows are now assigned to a custom 'AppUserModelID', that's why multiple icons may appear if Notepad2.exe is directly pinned to the taskbar. To fix this, open a window first, and then pin it to the taskbar from the Notepad2 taskbar button context menu.
Note that if you have followed the rest of his instructions on the <URL> and set it up to redirect 'notepad.exe' to 'notepad2.exe', you actually have to start up 'Notepad2.exe' directly, then right click on the taskbar instance and click "Pin to Taskbar".
Now that I did that, all my Notepad2 instances stack in the same place on the taskbar!
Note that the author of Notepad2 says that you have to add code in your application to handle this.
