[http://cure.org/curekids/kenya/2010/02/joseph_muchiri/](http://cure.org/curekids/kenya/2010/02/joseph_muchiri/)
When you look at the page, you'll see a toolbar sort of dash at the top of the page, but just below the site header (its the piece that says "CUREkids").
When you hover over any area of that toolbar there is a small green tab on the left that animates out from behind it (its the piece with the question mark on it). When clicked, the tab toggles open a descriptive [Slidedeck](http://www.slidedeck.com/) interface. So far all is well.
The problem is that if you mouse across the toolbar too quickly, there is a screwy glitch that causes the jQuery rules to fire in a strange way that results in the tab coming out from behind, but going back in overtop of the toolbar.
The way the script works is that the tab is hidden behind the toolbar by default, and the jQuery first animates it left to come out away from the toolbar, then changes the z-index to bring it actually over top of the toolbar element for maximum usability and clicking area on the tab. All this happens on mouseOver. On mouseOut the reverse occurs (z-index changed to lower than the toolbar, and then animates right back to where it was located).
I think there must be an issue with how the script is written that possibly could be tweaked so that when the mouseOver event happens so quickly it doesn't result in the overlap bug.
All help is appreciated.

3,893,429 | 1 | 3,893,455 | null | 4 | 1,667 | I'm designing an application that will use , and we have this that we need to map in our database. Some thing that looks like this (I'm pretty sure you all know what I'm talking about but I'll include a piece of the ERD just in case):
So it will have data stored that looks like this:
```
[1 | 0]
[2 | 1]
[3 | 2]
[4 | 2]
```
In other words:
```
Department 1
|__Department 2
|___Department 3
|___Department 4
```
And so on...
This will improve the number of records required on the table and the Data can be accessed using a [CONNECT BY](http://psoug.org/reference/connectby.html) command, just having 1 recor per department. We usually go for this tree structure as solution, but in this new application performance is a critical, so I was wondering what if I have a flattened-out table that would look like this.
```
[1 | 0]
[2 | 1]
[3 | 1]
[3 | 2]
[4 | 1]
[4 | 2]
```
This allows you to have very obvious relationships without having to know the parent Department for a given child to know who their upper hierarchy Departments are. But this increases the amount of data required since you need a record for each level a Department is in, meaning that if a have a Department 15 levels below the top one we would require 15 records for it.
The Department is pretty big so this may end up being a huge table (about 2 million records).
Ok, so after the brief introduction, this is the question; Has someone actually tried this that could tell me what is faster/less expensive for the DB between this two options, the huge flat table or the small tree one?

to

It allowed the solution to be loaded into VS2008. Afterwards I edited every csproj to target the Framework .NET 3.5
This allowed the projects to compile
I can run it in Release mode "correctly" (with some bugs due to modifications from .NET 4.0 specifics to 3.5 equivalent)
Now I got the following error message in debug mode
My google fu revealed that I could screw up the registry while searching for "The application you are trying to debug uses a version". It pointed me to [this page](http://msdn.microsoft.com/en-us/library/ms241897(v=VS.90).aspx)
I'm pretty sure there is an error on this page where it refers to 8.0 for both 2005 and 2008 help pages. So I did that, I created the registry key `CLRVersionForDebugging` with value "v3.5" just like the directory in `C:\Windows\Microsoft.NET\Framework` shows
Now I get the following message :
I can't find relevant information to solve this problem. This is a huge pain. I don't want to recreate the projects manualy, there are hundred of source/configuration files. Any help would be greatly appreciated.

I've created a class named `Room` and I am using a PropertyGrid to allow users to see and edit the properties of the `Room` instances. A few properties are restricted to a set of standard values. Thus I am using custom TypeDescriptors with `GetStandardValues()` overrides to get the property grid to show a drop down for those properties.
This was all working just fine. I was getting drop downs, and I could edit values no problem. Yet now for some reason when I select an `Room` the PropertyGrid shows the properties with the type descriptors as a black box.
If I click on the box it turns white and I get a blinking cursor, yet I can't type anything. If I then select another Room my program crashes with the following exception:

InnerException:
```
The last item in the stack trace points to my BuildingTypeConverter.GetStandardValuesSupported() method which is shown below.
```
GetStandardValuesSupported(System.ComponentModel.ITypeDescriptorContext context)
{
Room r = (Room)context.Instance; //this is line 14 referenced by the InvalidCastException's stack trace
if (r.IsLinked)
{
return true;
}
else
{
return false;
}
}
```
Now if I set a breakpoint at line 14 above and try to debug the debugger does not break at the breakpoint. In addition, if I add arbitrary code before the cast the stack trace from the InvalidCastException always seems to reference to first line of GetStandardValues() regardless of what it is. For example I tried the following.
```
public override bool GetStandardValuesSupported(System.ComponentModel.ITypeDescriptorContext context)
{
string s = "hello world"; //FIRST LINE
int i = 0;
Room r = (Room)context.Instance;
.....
```
I still got the same InvalidCastException. Yet it's stack trace reference the first line above where I initialize `string s`. In addtion, if I tried to set a breakpoint on this first line it was also not triggered.
Like I said before this working just fine a day or so ago. I've even tried rolling back to previous revisions in my SVN repository. I've gone as far back as the first revision were I created the custom Type Descriptor class but still run into the problem with the `InvalidCastExceptions`. Does anyone have any idea what's going on?

3,895,302 | 1 | 3,909,314 | null | 2 | 1,288 | I have a solution with quite a few different MasterPages / BasePages which all inherit from somewhere else. My problem is that I have a virtual string in BaseMaster, which is overridden by BaseManagement, but when I try to access this string I always get the base value
The point of inheriting masters and pages is obviously to avoid having duplicate code everywhere.
Maybe it has something to do with the fact that I "need" `protected void Page_Load(object sender, EventArgs e)` at every master no matter
So, here's an snippet from Base.Master.cs
```
public abstract partial class BaseMaster : MasterPage, IRewritablePageElement
{
public BasePage BasePage { get { return Page as BasePage; } }
public BaseMaster Self { get { return (BaseMaster)this.Page.Master; } }
public virtual string accessUri { get { return "/"; } }
public string AccessUri { get { return Self.accessUri; } }
protected void Page_Load(object sender, EventArgs e)
{
this.OnPageLoad(sender, e);
}
/// <summary>
/// If we want to do something on page load, we override the following method
/// </summary>
public virtual void OnPageLoad(object sender, EventArgs e)
{
SetCacheability();
RedirectSiteDown();
RedirectUnregisteredUsers();
RedirectUnprivilegedUsers();
if(!IsPostBack)
{
PopulateMenu();
...
```
As you already noticed,
```
public BaseMaster Self { get { return (BaseMaster)this.Page.Master; } }
public virtual string accessUri { get { return "/"; } }
public string AccessUri { get { return Self.accessUri; } }
```
is as ugly as it gets, since it should just be
```
public virtual string AccessUri { get { return "/"; } }
```
but the code somehow manages to get all the way down to a level where AccessUri is "/" even though it has been overriden with "/a/" somewhere at a higher level:
```
public partial class BaseManagementMaster : BaseMaster
{
public override string accessUri { get { return "/a/"; } }
protected void Page_Load(object sender, EventArgs e)
{
}
}
```
If not for the `Self` thingy, here AccessUri is still "/". which makes absolutely no sense.
Also, the fact that I have to re-declare Page_Load methods makes very little sense too.
Is there a clean way to do master page inheritance, is it even realistically possible?

The minutes in working hours that is being calculated are discarded. I only get the value in full hour. Snapshot example:
My main concern is on workingHours and wageAmount
workingHours is displayed as 5. Here is the time sheet snapshot:
As you see shift starts at 10:30 AM and ends at 4:00 PM (excluding lunch time), so the actual total hours is 4 and a half not 5.
Here is the query snippet that calculates the hours:
```
DATEDIFF(HOUR, shiftStart.timeEntered, shiftEnd.timeEntered) - DATEDIFF(HOUR, lunchStart.timeEntered, lunchEnd.timeEntered) AS workingHours,
```
Since i will be counting the minutes, i will have to calculate the wage per minute so i will have to put the following code that calculates wage per minute:
```
ROUND((((DATEDIFF(HOUR, shiftStart.timeEntered, shiftEnd.timeEntered) - DATEDIFF(HOUR, lunchStart.timeEntered, lunchEnd.timeEntered)) * 60) * (cast(((w.wageAmount/60)-((w.wageAmount/60)%.001)) as decimal (18,3)))), 0) AS "SalaryPerMin",

The problem is that it also adds 1 make and 1 model to the core data, so i get duplicates.
for example, in the following code, it saves 1 car object 2 models, and 2 makes,
so I get a duplicate Make in my table (2 "Nissan").
How can i avoid this? is it possible to create primary keys?

Additionally under [EdgeRenderingFunction](http://reference.wolfram.com/mathematica/ref/EdgeRenderingFunction.html) documentation in "More

This looks useful but unfortunately there is no coded examples to try.
Taking that very literally I tried things like

-> 1, 2 -> 4, 4 -> 5, 4 -> 6}, VertexLabeling -> True,
EdgeRenderingFunction -> g[{1, 2}, {1,

I have a conceptual architecture, where there is a central server, which allows clients to connect to it via XML web services. There are 2 types of client, producers and consumers.
The system is built in C# using WCF WebServices, specifically IIS webservices (though this can be changed if necessary)
Producers publish information to the server, and consumers consume information uploaded by a producer.
The conundrum... Consumers need to somehow subscribe to an event on the server, which is thrown when a producer updates the web server, downloading new content and displaying it if necessary.
I don't want to use a polling mechanism, but can't see a way to subsribe to server events in a client.
Very basic architecture... Workstations could be the same PC running 2 services, or they could be 2 separate PC's on different networks. They don't about each other, so all comms are done through the webservice.
This application is for a messaging network, based on radio paging.

I have this textarea inside a table which is inside a DIV and it seems that it causes the entire table to stretch out of its bounds.
You can see an example of the same situation even in a more simple case, just putting a text area inside a div (like what is used here in www.stackoverflow.com)
You can see from the images below that the textarea can stretch beyond the size of its parent? How do I prevent this?
I'm kind of new to CSS so I don't really know what CSS attributes should I be using. I tried several like , and .
But they don't seem to do the trick.
Anything else I might have missed?
UPDATE:
HTML
CSS
```
textarea {
max-width: 50%;
}
#container {
width: 80%;
border: 1px solid red;
}
#cont2{
width: 60%;
border: 1px solid blue;
}
```
If you put this code inside the [http://jsfiddle.net](http://jsfiddle.net),
you will see that they act differently. Although the textarea is limited to the percentage declared in its css style, it is still possible to get it to cause its parent table to be as large as it wants to be, and then you can see that it spills over its parent border.
Any thoughts on how to fix this?

If you are using H[udson CI server](http://hudson-ci.org/), there is such a feature in `Administration > Usages statistics` option. Here is an example:
In my application, I already have a function that returns the number of calculations. So my idea is to periodically call this method, for example every 10 minutes (using [Quartz](http://www.quartz-scheduler.org/)) in order to retrieve the number of running calculations and store it in a `int[]`. Every day, this `int[]` is stored in an external file, and cleaned. So after some days, the content of this file will look like:
```
data.20101008=1;2;1;0;1;1;0;0;0;0;....;0
data.20101009=1;0;1;1;0;0;0;0;3;2;....;0
data.20101010=1;2;1;0;1;1;2;3;4;4;....;2
...
```
(I simplified a little this processing, as I want to update this file more frequently, in case of engine shutdown, or something like that)
To summarize, my idea is to store in a `properties` file the number of running calculations for a specific day. Eventually, I can provide a function that returns this data as a `Map<Date, int[]>`.
Finally, I will use [JFreeChart](http://www.jfree.org/jfreechart/) to display these data in a graphical
What do you think of this idea? Any advice to enhance this process?
Note that this functionality is one a feature, so I don't want to build too complex systems.

I've tried converting the image to PVRTC and that did give an extra fps or two. I get identical framerates using a 1024x768 image instead of the tiled version.

3,900,392 | 1 | 3,900,422 | null | 8 | 8,766 | I am trying to draw a repeating background image in my NSView, I have this till now:
```

self.backgroundImage = [NSImage imageNamed:@"progressBackground.pdf"];
}
return self;
}
// DRAW

// Draw the background
[backgroundImage drawInRect:[self bounds]
fromRect:NSMakeRect(0.0f, 0.0f, backgroundImage.size.width, backgroundImage.size.height)
operation:NSCompositeSourceAtop
fraction:1.0f];
NSLog(@"%dx%d", backgroundImage.size.width, backgroundImage.size.height);
}
```
However, the view stretches the image to fill itself. I want the image to repeat instead.
(the black strokes are fixed already)
Also, something strange happens, as the console says the size of the image equals `-2109897792x0`, but the image really is `32x32`! WTF?!
Could someone help me, please? Thanks.

```

C1 to C3 are draggable elements, and I haven't applied any constraint on it, because when I'm out of #containment, I automatically resize it.
```

var size = $.extend({}, $("#containment").data("originalSize"));
$.each($("#containment > div"), function(index, d) {
width = parseInt($(d).css("left"), 10) + parseInt($(d).outerWidth(), 10);
height = parseInt($(d).css("top"), 10) + parseInt($(d).outerHeight(), 10);
size.width = (width > size.width) ? (width + 50) : size.width;
size.height = (height > size.height) ? (height + 50) : size.height;
});
$("#containment").animate({
width: size.width,
height: size.height

```
Problem is, when dragstop is fired, the child I moved out is hidden and appears only when the #containment animation is over it.
In my Screen B1 and B2 have the same size, just B1 isn't totally visible because animation is running...

3,900,852 | 1 | 3,901,693 | null | 2 | 612 | I'm trying to fill a `DataGrid` with an anonymous type generated by a LINQ query. When I put the query results in a list box, it appears fine. However, when I put the query results in a data grid, the correct number of rows are generated, but the cells are empty.
(The data grid is on the left, with the list box on the right.)
Assigning the data source:
```
testListBox.ItemsSource = debtPerUser.ItemsSource = ExpenseViewModel.getDebtData(username);
```
The XAML:
```
<sdk:DataGrid Height="222" HorizontalAlignment="Left" Margin="31,89,0,0" Name="debtPerUser" VerticalAlignment="Top" Width="516" AutoGenerateColumns="True" />
<ListBox Height="222" HorizontalAlignment="Left" Margin="567,89,0,0" Name="testListBox" VerticalAlignment="Top" Width="173" />
```
What could I be doing wrong here?
getDebtData:
```
internal static IEnumerable getDebtData(string username)
{
IEnumerable<String> users = getUsersInvolving(username);
var debt = from user in users
select new {
User = user,
Net = owedBetween(username, user) - owedBetween(user, username)
};
return debt.Where(d => d.Net != 0);
}
```
: It works when I'm not using an anonymous query type. Perhaps that's the problem?

After you hit the button, you get an action sheet asking you whether you really want to do it, and then presumably there is some callback based on the user's input.
Also noticed that the Nike + iPod settings have a clear button in them, but again, that app might have access to internal APIs that we don't.

3,901,322 | 1 | 3,901,500 | null | 2 | 145 | I have a project that I am working on and I can't figure out which would be a "better" table relationship schema.
The scope of the area in question are:
- User uploads documents (become the owner/author)- User can share document with other users (set share rights)- Any user who has access to document can checkout the document (exclusive lock)
My original schema looks like this:
Benefits are:
- only one user can be author. (authorid)- Rights table contain only "sharerights" (Read, Write)- User has easy distinction as to which files they "own" (authorid) vs sharedfiles (sharedfiles table). (this one is a weak benefit, I know)
After thinking things through I thought that this might be a better schema:
Benefits are:
- All document associations are located in one location (UserFiles)- Future ability to allow multiple authors/owner of a single document
Rights table would now have Read, Write, and Owner. As soon as a document was uploaded by a user, an automatic association would be made to a new document and the user would be given "owner" rights.
This led me to the final schema:
Benefits are:
-
The only problem with this last model is that I plan to add "special" user for each department so that a user could share a document to an entire department. So I am not sure if I want to associate the share association to the checkoutID (if that makes sense). The query for the users files would look like "select all files where userfiles.userid = me.userid || (userfiles.id == SpecialDepID && me.depid == SpecialDepID)" (major pseudo code)
It has been a long time since I have done database schemas and this one design decision is really racking my brain. It is really bugging me as to which design would be "better" and by better I mean better design principles, better decision based off of previous experience, allows for easier "growth" in the design, etc. Please let me know your thoughts!
## FINAL SOLUTION
With the help from Michael Madsen the final solution looks like:
There will be a trigger on UserFiles for delete which will determine if a lock should be deleted when a relationship is removed.

// First get the image into your data buffer

NSUInteger height = CGImageGetHeight(imageRef);
CGColorSpaceRef colorSpace = CGColorSpaceCreateDeviceRGB();
unsigned char *rawData = malloc(height * width * 4);
NSUInteger bytesPerPixel = 4;
NSUInteger bytesPerRow = bytesPerPixel * width;
NSUInteger bitsPerComponent = 8;
CGContextRef context = CGBitmapContextCreate(rawData, width, height,
bitsPerComponent, bytesPerRow, colorSpace,
kCGImageAlphaPremultipliedLast | kCGBitmapByteOrder32Big);
CGColorSpaceRelease(colorSpace);
CGContextDrawImage(context, CGRectMake(0, 0, width, height), imageRef);
CGContextRelease(context);
// Now your rawData contains the image data in the RGBA8888 pixel format.
int byteIndex = (bytesPerRow * yy) + xx * bytesPerPixel;
for (int ii = 0 ; ii < count ; ++ii)
{
CGFloat red = (rawData[byteIndex] * 1.0) / 255.0;
CGFloat green = (rawData[byteIndex + 1] * 1.0) / 255.0;
CGFloat blue = (rawData[byteIndex + 2] * 1.0) / 255.0;
CGFloat alpha = (rawData[byteIndex + 3] * 1.0) / 255.0;
byteIndex += 4;
UIColor *acolor = [UIColor colorWithRed:red green:green blue:blue alpha:alpha];
[result addObject:acolor];
}
free(rawData);
return result;
}
```
The problem is, the images are being captured from the iPhone's camera so they are not exactly the same position. I need to create areas of a couple of pixels and extracting the general color of the area (maybe by adding up the RGBA values and dividing by the number of pixels?). How could I do this and then translate it to a CGMask?
I know this is a complex question, so any help is appreciated.
Thanks.

The part that is losing me is that its telling me to display the passenger manifest in a list box, but then its telling me to display it in a list box. Then it calls it a rich text box again. The screenshots provided with the assignment only show one display box. One of the events that is supposed to be included is a double click on an item in the manifest display. When the flight is closed, it tallies up your first class and business class passengers and displays that info in the same display box.
So my question is, was list box somehow incorporated into the rich text box? I thought maybe it was just overlayed, but later screenschots show the display box filled and scrolled down, as if it were all the same text box, rather than just a list box or rich text. I'm confused. Obviously, I'm not looking for anyone to do my work for me, but it doesn't appear this was covered in our material.

There is an implementation on Google Video that has exactly what I am looking for: the option to speed up or slow down the video and continue to play the audio. The screenshot is below.
I know that Flowplayer has an option to slow down or speed up video when implemented with Wowza server. However, when using that approach, there is no sound.
I have also seen the option from Enounce called MySpeed that allows video to be slowed or quickened, but this requires a browser plugin which is too much of a barrier for our users.
So here's the question: How does Google do it? How can you add an option to a flash player to slow down or speed up video?
Here is a screen shot. You can see the option to change the speed of the video to 1.5x. It also has options to go to 0.5x, 1.25x, 1.5x, 1.75x, 2.0x, 2.5x, and 3.0x.

3,902,833 | 1 | 3,902,850 | null | 0 | 1,911 | I have a mystery 1px bottom border showing up in Safari and Chrome (I guess a WebKit thing). Firefox displays it fine.
The button below should sit flush with the bar beneath. There should not be that 1px line separating them.
I've played around with `height`, `border`, `position`, `padding` and `margin` but haven't been able to figure this one out.
Changing `bottom: 0` to `bottom: -5px` in Web Inspector still produces the line.
There are quite a lot of styles going into it, so I'll try and amalgamate the cascade.
```
#tell-a-friend {
background-repeat:no-repeat;
display:block;
height:33px;
margin-right:0;
position:absolute;
float:right;
font-size:1.2em;
margin-right:0.8em;
background-position:right 0;
bottom:0;
height:35px !important;
left:682px;
width:82px;
}
```
Then again, I may be better off [linking to the site](https://www.bustersdirect.com.au/).
The CSS is minified, so use Web Inspector to view the CSS.
I've tried everything I can think of right now, so I'm going to see if you guys can help me :)
Many thanks!

3,903,011 | 1 | 3,904,046 | null | 2 | 1,302 | I'm having quite a bit of trouble trying to get inheritance to work in EF4. The original model is quite large, however I have managed to replicate it in a model of just two entities.
Essentially the two tables are "Asset" and "Questionnaire". Questionnaire inherits Asset (i.e. Questionnaire is an Asset). They do this by Questionnaire having an AssetID linking back to the Asset. Technically the design may not be the best however I'm trying to make this work for a 10 year old database without any major redesigns...
So given that, the tables are:
- -
- - -
The model for this is extremely simplistic - essentially it is:

2. Error 2 Error 3003: Problem in mapping fragments starting at line 87:All the key properties (Assets.AssetID) of the EntitySet Assets must be mapped to all the key properties (Content_Questionnaire.Id) of table Content_Questionnaire.
How on earth do I get rid of these errors?
It is probably something completely obvious that I am missing - however help or even a nudge in the right direction would be greatly appreciated. I've been getting a few grey hairs trying to work through this one today!
Thanks in advance for any help you may be able to shed.

3,903,085 | 1 | 3,903,168 | null | 4 | 2,956 | I'm building a UITableView similar to iPod.app's album browsing view:
I'm importing all the artists and album artworks from the iPod library on first launch. Saving everything to CoreData and getting it back into an NSFetchedResultsController. I'm reusing cell identifiers and in my `cellForRowAtIndexPath:` method I have this code:
```
Artist *artist = [fetchedResultsController objectAtIndexPath:indexPath];
NSString *identifier = @"bigCell";
SWArtistViewCell *cell = (SWArtistViewCell*)[tableView dequeueReusableCellWithIdentifier:identifier];
if (cell == nil)
cell = [[[SWArtistViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:identifier] autorelease];
cell.artistName = artist.artist_name;
cell.artworkImage = [UIImage imageWithData:artist.image];
[cell setNeedsDisplay];
return cell;
```
My SWArtistViewCell cell implements the `drawRect:` method to draw both the string and image:
```
[artworkImage drawInRect:CGRectMake(0,1,44,44)]
[artistName drawAtPoint:CGPointMake(54, 13) forWidth:200 withFont:[UIFont boldSystemFontOfSize:20] lineBreakMode:UILineBreakModeClip];
```
Scrolling is still choppy and I just can't figure out why. Apps like iPod and Twitter have butter smooth scrolling and yet they both draw some small image in the cell as I do.
All my views are opaque. What am I missing?
: here's what Shark says:
I'm not familiar with Shark. Any pointer as of what are these symbols related to? When I look at the trace of these, they all point to my drawRect: method, specifically the UIImage drawing.
Would it point to something else if the chokehold was the file reading? Is it definitely the drawing?
I've done as pothibo suggested and added an artworkImage method to my Artist class that retains the image created with imageWithData:
```
- (UIImage*)artworkImage {
if(artworkImage == nil)
artworkImage = [[UIImage imageWithData:self.image] retain];
return artworkImage;
}
```
So now I can directly set the retained image to my TableViewCell as follow:
```
cell.artworkImage = artist.artworkImage;
```
I also set my setNeedsDisplay inside the setArtworkImage: method of my tableViewCell class. Scrolling is still laggy and Shark shows exactly the same results.

The absolute deviation is the sum of the absolute difference between each item in a vector and the mean:
> 
I know that the variance of a vector can be calculated in such a manner. Variance is similar to absolute deviation, but each difference is squared:

The online algorithm for variance is as follows:
```
n = 0
mean = 0
M2 = 0
def calculate_online_variance(x):
n = n + 1
delta = x - mean
mean = mean + delta/n
M2 = M2 + delta*(x - mean) # This expression uses the new value of mean
variance_n = M2/n
return variance_n
```
Is there such an algorithm for calculating absolute deviance? I cannot formulate a recursive definition myself, but wiser heads may prevail!

2. Latest and not Auth.User from the session because - when i edit the profile content like name or photo. it still references to the old data that was stored when user had logged on.
3. It has to be displayed on every page like the Stackoverflow User info at the top
Which is the best way to do it ?

It would be enough to know how to make it for a static size of y and z;

3,904,575 | 1 | null | null | 12 | 8,301 | I have a background thread that loads images and displays them in the main thread. I noticed that the background thread has almost nothing to do, because the actual image decoding seems to be done in the main thread:
So far I’ve tried calling `[UIImage imageNamed:]`, `[UIImage imageWithData:]` and `CGImageCreateWithJPEGDataProvider` in the background thread with no difference. Is there a way to force the decoding to be done on the background thread?
There’s already [a similar question](https://stackoverflow.com/questions/1815476) here, but it does not help. As I wrote there, I tried the following trick:
```
@implementation UIImage (Loading)
- (void) forceLoad
{
const CGImageRef cgImage = [self CGImage];
const int width = CGImageGetWidth(cgImage);
const int height = CGImageGetHeight(cgImage);
const CGColorSpaceRef colorspace = CGImageGetColorSpace(cgImage);
const CGContextRef context = CGBitmapContextCreate(
NULL, /* Where to store the data. NULL = don’t care */
width, height, /* width & height */
8, width * 4, /* bits per component, bytes per row */
colorspace, kCGImageAlphaNoneSkipFirst);
NSParameterAssert(context);
CGContextDrawImage(context, CGRectMake(0, 0, width, height), cgImage);
CGContextRelease(context);
}
@end
```
That works (forces the image to decode), but it also triggers an apparently expensive call to `ImageIO_BGR_A_TO_RGB_A_8Bit`.

3,904,768 | 1 | 3,904,886 | null | 2 | 1,772 | maybe some of you know that there are GPS tools out there that are used in Motorsports. A lot of them deliver the following function: If you drive with your car and you press a button at a certain point this GPS Coordinate will be stored and every time you drive over this coordinate a LapTime will be stored. For a small application a need a similar function. But here is my problem: Since you will never hit the exact Coordinate twice these tools store the coordinates of a Line and if you hit one of the coordinates of this line the Lap is finished. How do I calculate such a line? If you look at my Picture, the red dot is the coordinate where the user hits the button to start a lap and the green Line is what the device stores and uses as a virtual finish line and not only the Coordinate where the red dot is. Any Idea how I can calculate such a line? I really don't get it since the line is never ideal directed to north or south.
Thank you very much

I'm having some trouble to get how Forms work in MVC (as I'm a WebForms Developer and really wanna start using MVC in one big project)
I took the and add a simple ViewModel to it
```
namespace TestForms.Models
{
public class myFormViewModel
{
public myFormViewModel() { this.Options = new List<myList>(); }
public string Name { get; set; }
public string Email { get; set; }
public List<myList> Options { get; set; }
}
public class myList
{
public myList() { this.Value = this.Name = ""; this.Required = false; }
public string Name { get; set; }
public string Value { get; set; }
public string Type { get; set; }
public bool Required { get; set; }
}
}
```
Created a , passed a new object to the view and run it.
When I press submit, it does not return what's in the `Options` part... ?

Changing the View loop to allocate the sequential number, we now have
```
<%= Html.TextBox("model.Options[" + i + "].Value", option.Value)%>
```
`model` is the name of our Model variable that we pass to the View
`Options` is the property name that is of type `List`
and then we use the property name

I'm trying to get a website I've developed on one computer, to work on my home computer. The old computer was running ASP.net 3.5.
On my new computer, after installing IIS and ASP.net 3.5:
I get the following error:
Upon checking the application pool, it says it is running ASP.net 2.0:
And there is no option to change it to 3.5:
I've checked regedit for the installed .net versions and 3.5 is listed there as installed. I just can't seem to get my site to run with 3.5, or run at all without any strange IIS error messages.
This thread: [http://forums.asp.net/p/1184937/2018939.aspx](http://forums.asp.net/p/1184937/2018939.aspx) suggests that 2.0 showing is correct, my issue then is why is the site not running?

I passed this method(function) in a thread but problem is that every time when I click on the image of artist(button) new threads starts running and then multiple songs gets started playing concurrently. How can I use "NSOperation and NSOperationQueue" so that only one song will run at a time . Please help.
Thanks in advance
Now I am able to play song by adding them in queue but when songs starts playing i m not able to do anything on my Screen until song is finished or I scroll the table.

But `.main-content` is isn't suppose to be wrapping the 3 columns...

Procedure or function 'sp_cdc_enable_table' expects parameter '@role_name', which was not supplied. Intellisense popup on (having mouse cursor on) sp_cdc_enable_table in SSMS shows:
> stored procedure AdventureWorksDW.sys.sp_cdc_enable_table
@source_schema sysname,
@source_name sysname,
@supports_net_changes ,
@role_name sysname,
@index_name sysname =null,
[continuation truncated by vgv8]
Does not " = null" imply default value which is used if parameter is omitted?
Why does not ommission of @index_name sysname give the error?
Collateral questions:
How can I copy the text of popup description into buffer (for further pasting)?
Is not "@role_name bit = null" in popup an error (and should have been "@role_name bit = 0, " instead)?
Update:
I corrected the typo in post.
Really I executed
> sp_cdc_enable_table 'dbo', 'FactInternetSales'--, @role_name=NULL, @supports_net_changes=0
i.e. both variants are execution of the same script
1) uncommented
2) with comments
OK, initially I typed incorrectly the text of popup which I corrected now.
So, the question about error is removed, thanks.
From the context of my successful execution of 1) you are supposed to notice that my questions are about popup (but not how to succeed):
- - - -
Notice that popup also has "@capture_instance = null," which can be completely ommitted but it is not marked this in any way.
I included the screenshot.
Well, it is rather context sensitive help.
Intellisense does not work at all on sys.sp_* and popup is not shown if there is a syntax error - whatever MS pretended to accomplish by such "help" since it is necessary to insert full correct statement in order to escape syntax errors and have context sensitive "help"...
Update5:
Then, what is the sense that parameters with default values cannot be dropped?
