4,565,679 | 1 | null | null | 14 | 14,520 | i need to tell a printer driver to issue a form feed.
i'm printing directly to a printer using the:
- [OpenPrinter](http://msdn.microsoft.com/en-us/library/dd162751(VS.85).aspx)- [StartDocPrinter](http://msdn.microsoft.com/en-us/library/dd145115(VS.85).aspx)- [StartPagePrinter](http://msdn.microsoft.com/en-us/library/dd145117(VS.85).aspx)- [WritePrinter](http://msdn.microsoft.com/en-us/library/dd145226(VS.85).aspx)- [EndPagePrinter](http://msdn.microsoft.com/en-us/library/dd162597(VS.85).aspx)- [EndDocPrinter](http://msdn.microsoft.com/en-us/library/dd162595(VS.85).aspx)- [ClosePrinter](http://msdn.microsoft.com/en-us/library/dd183446(VS.85).aspx)
set of API calls.
A lot of the inspiration came from [KB138594 - HOWTO: Send Raw Data to a Printer by Using the Win32 API](http://support.microsoft.com/kb/q138594/). An important point to note in that KB article is that they (and my copied code) start the document in `RAW` mode:
```
// Fill in the structure with info about this "document."
docInfo.pDocName = "My Document";
docInfo.pOutputFile = NULL;
docInfo.pDatatype = "RAW";
StartDocPrinter(hPrinter, 1, docInfo);
```
> `RAW` mode (as opposed to `TEXT` mode) means we are issuing raw bytes to the printer driver. We promise to talk in the language it understands.
We can then use `WritePrinter` to write everything we want:
```
WritePrinter(hPrinter, "Hello, world!"); //note, extra parameters removed for clarity
WritePrinter(hPrinter, 0x0c); //form-feed
```
The problem here is the `0x0c` form-feed character. Because we've opened the printer in `RAW` mode, we are promising we will send the printer driver bytes it can process. The drivers of printers take `0x0C` to mean you want to issue a form-feed.
The problem is that other printers (, ) expect print jobs to be in their own printer language. If you use the above to print to an XPS or PDF printer: nothing happens (i.e. no save dialog, nothing printed).
i [asked for a solution to this question a while ago](http://social.msdn.microsoft.com/forums/en-US/windowsxps/thread/6280ebb0-61ad-4c42-a870-7f022fcdfbfe/), and a response was that you have to change the document mode from `RAW`:
```
docInfo.pDatatype = "RAW";
```
to `TEXT`:
```
docInfo.pDataType = "TEXT";
```
> Well this probably is because you send
"RAW" data directly to the printer,
and RAW can be any PDL. But the XPS
driver will probably only understands
XPS, and it will probably just ignore
your "unknown: Hello, world!0xFF" PDL. The
XPS driver will probably, if any, only
accept XPS data when you write
directly to it.If you want to render text on the XPS
driver, you should use GDI. You might
be able to send plain text to the
driver if you specify "TEXT" as the
datatype. The print processor attached
to the driver will then "convert" the
plaintext for you by rendering the job
via GDI to the driver.
So that worked, i changed my code to declare the print document as `TEXT`:
```
// Fill in the structure with info about this "document."
docInfo.pDocName = "My Document";
docInfo.pOutputFile = NULL;
docInfo.pDatatype = "TEXT";
StartDocPrinter(hPrinter, 1, docInfo);
WritePrinter(hPrinter, "Hello, world!");
WritePrinter(hPrinter, 0x0c); //form-feed
```
And then the dialog for XPS and PDF printers appear, and it saves correctly. And i thought all was fixed.
Except months later, when i tried to print to a <quote>real</quote> printer: the form-feed doesn't happen - presumably because i am no longer printing in "raw printer commands" mode.
So what i need is the way of issuing a form feed. i need the API call that will tell printer driver that i want the printer to perform a form-feed.
How to tell a printer to issue a Form-Feed during printing?
---
## Background on Data Types
The print processor tells the spooler to alter a job according to the document data type. It works in conjunction with the printer driver to send the spooled print jobs from the hard drive to the printer.
Software vendors occasionally develop their own print processors to support custom data types. Normally, the print processor does not require any settings or intervention from administrators.
The Windows printing process normally supports five data types. The two most commonly used data types, enhanced metafile (EMF) and ready to print (RAW), affect performance in different ways on both the client computer and the print server computer.
`RAW` is the default data type for clients other than Windows-based programs. The RAW data type tells the spooler not to alter the print job at all prior to printing. With this data type, the entire process of preparing the print job is done on the client computer.
`EMF`, or enhanced metafile, is the default datatype with most Windows-based programs. With EMF, the printed document is altered into a metafile format that is more portable than RAW files and usually can be printed on any printer. EMF files tend to be smaller than RAW files that contain the same print job. Regarding performance, only the first portion of a print job is altered, or rendered on the client computer, but most of the impact is on the print server computer, which also helps the application on the client computer to return control to the user faster.
The following table ([taken from MSDN](http://technet.microsoft.com/en-us/library/bb490764.aspx)) shows the five different data types supported by the default Windows print processor:
: `RAW`
: Print the document with no changes.
: This is the data type for all clients not based on Windows.
: `RAW [FF appended]`
: Append a form-feed character (0x0C), but make no other changes. (A PCL printer omits the document's last page if there is no trailing form-feed.)
: Required for some applications. Windows does not assign it, but it can be set as the default in the Print Processor dialog box.
: `RAW [FF auto]`
: Check for a trailing form-feed and add one if it is not already there, but make no other changes.
: Required for some applications. Windows does not assign it, but it can be set as the default in the Print Processor dialog box.
: `NT EMF 1.00x`
: Treat the document as an enhanced metafile (EMF) rather than the RAW data that the printer driver puts out.
: EMF documents are created by Windows.
: `TEXT`
: Treat the entire job as ANSI text and add print specifications using the print device's factory defaults.
: This is useful when the print job is simple text and the target print device cannot interpret simple text.
You can see the print processors available for a printer, and the data types that each processor supports, through the properties of a printer in the control panel:

4,566,385 | 1 | 4,566,729 | null | 6 | 1,212 | I'm trying to design a page that has two columns of content, div#left and div#right. (I know these aren't proper semantic identifiers, but it makes explaining easier) The widths of both columns are fixed.
When the viewport is too narrow to display both side-by-side, , like this:
My first thought was simply to apply `float: left` to #left and `float: right` to #right, but that makes #right itself to the right side of the window (which is the proper behavior for `float`, after all), leaving an empty space. This also leaves a big gap between the columns when the browser window is really wide.
Applying `float: left` to divs would result in the wrong one moving to the bottom when the window was too small.
I could probably do this with media queries, but IE doesn't support those until version 9. The source order is unimportant, but I need something that works in IE7 minimum. Is this possible to do without resorting to Javascript?

I am working on a very low level app. I have an array of bytes in memory. Those are characters. They were rendered with anti-aliasing: they have values from 0 to 255, 0 being fully transparent and 255 totally opaque (alpha, if you wish).
I am having trouble conceiving an algorithm for the rendering of this font. I'm doing the following for each pixel:
```
// intensity is the weight I talked about: 0 to 255
intensity = glyphs[text[i]][x + GLYPH_WIDTH*y];
if (intensity == 255)
continue; // Don't draw it, fully transparent
else if (intensity == 0)
setPixel(x + xi, y + yi, color, base); // Fully opaque, can draw original color
else { // Here's the tricky part
// Get the pixel in the destination for averaging purposes
pixel = getPixel(x + xi, y + yi, base);
// transfer is an int for calculations
transfer = (int) ((float)((float) (255.0 - (float) intensity/255.0) * (float) color.red + (float) pixel.red)/2); // This is my attempt at averaging
newPixel.red = (Byte) transfer;
transfer = (int) ((float)((float) (255.0 - (float) intensity/255.0) * (float) color.green + (float) pixel.green)/2);
newPixel.green = (Byte) transfer;
// transfer = (int) ((float) ((float) 255.0 - (float) intensity)/255.0 * (((float) color.blue) + (float) pixel.blue)/2);
transfer = (int) ((float)((float) (255.0 - (float) intensity/255.0) * (float) color.blue + (float) pixel.blue)/2);
newPixel.blue = (Byte) transfer;
// Set the newpixel in the desired mem. position
setPixel(x+xi, y+yi, newPixel, base);
}
```
The results, as you can see, are less than desirable. That is a very zoomed in image, at 1:1 scale it looks like the text has a green "aura".
Any idea for how to properly compute this would be greatly appreciated.

4,567,407 | 1 | 4,571,894 | null | 1 | 841 | I'm building a panel control that makes use of jQuery UI tabs, and looks like this:
The tabs are in the header and the tab panels are nested inside the parent element under a single containing (`div.form-panel-contents`) that I use for expanding/collapsing the panel contents. The problem is when I collapse the containing div via slideUp, somehow Tabs detects that the tab panels container is not visible and applies the CSS class `ui-tabs-hide` to each of the nested tab panels, which sets all tab panels to `display: none`.
`ui-tabs-hide`
When I change the state of the containing div I want the state of the tab panels to remain intact, so that the slide up/down looks fluid. I'm also curious how the tool even detects that the parent element was collapsed in the first place.

Basically I'd like to know how to connect nodes. I have my own datastructures that I can already determine the neighbors and the distance. I'd now like to convert that into this posted datastructure so I can run it through the AStar algorithm.
I was seeking something more like:
```
Path<EdgeNode> startGraphNode = new Path<EdgeNode>(tempStartNode);
startGraphNode.AddNeighbor(someOtherNode, distance);

4,567,644 | 1 | 4,567,680 | null | 1 | 884 | Suppose I have some arbitrary input image with width and height . I want to rotate this image all the way around 360 degrees back to the starting position. However, if the image is of anything except a circle, then the edges of the image will be clipped if the canvas it is drawn onto remains at size by .
What I need then is to determine the canvas size (width and height ) that can be used for all rotated versions of the input image. I know that == , and thus the desired canvas size is a square, because it is obvious that we are rotating something about a center point, and the final image (after 360 rotations) is essentially a circle.
The other thing to consider is that objects such as squares will have corners that will stick out, so just using the max value of width or height for both dimensions also does not work.
One solution I have come up with is to create the canvas larger than I need (for example by setting and to `max(w1, h1) * 2`, rotating everything, and then trimming all the transparent pixels. This is not very efficient and I would much rather be able to calculate the tightest bounding box upfront.

Second, when I touch those link-like words, the text view (or maybe web view) jumps to the corresponding part below (yes, it doesn't open Safari, it just jumps to the text within that text/web view)
Now I want to implement the same effects.
1. I should base my implementation on what? UITextView or UIWebView?
2. How to make normal words look like links?
3. How to make those smooth jumps within such a text/web views?

4,568,070 | 1 | 4,656,209 | null | 1 | 378 | This is difficult to explain without illustration, so - behold, an illustration, cobbled together from screenshots of a few hello-world examples and a lot of Paint work:
I have started out using Windows Forms on .NET (via IronPython, but that shouldn't be important), and haven't been able to figure out very much. GUI libraries in general are very intimidating, simply because every class has so many possible attributes. Documentation is good at explaining what everything does, but not so good at helping you figure out what you need.
I will be assembling the GUI dynamically, but I'm not expecting that to be the hard part. The sticking points for me right now are:
- How do I get text labels to size themselves automatically to the width of the contained text (so that the text doesn't clip, and I also don't reserve unnecessary space for them when resizing the window)?- How do I make the vertical scrollbar always appear? Setting the VScroll property (why is this protected when AutoScroll is public, BTW?) doesn't seem to do anything.- How come the horizontal scrollbar is not added by AutoScroll when contents are laid out vertically (via `Dock = DockStyle.Top`)? I can use a minimum size for panels to prevent the label and corresponding control from overlapping when the window is shrunk horizontally, but then the scrollbar doesn't appear and the control is inaccessible.- How can I put limits on window resizing (e.g. set a minimum width) without disabling it completely? (Just set minimum/maximum sizes for the Form?) Related to that, is there any way to set minimum/maximum widths or heights without setting a minimum/maximum size (i.e. can I constrain the size in only one dimension)?- Is there a built-in control suitable for hex editing or am I going to have to build something myself?
... And should I be using something else (perhaps something more capable?) I've heard WPF mentioned, but I understand that this involves XML and I really want to build a GUI from XML - I already have data in an object graph, and doing some kind of weird XML pseudo-serialization (in Python, no less!) in order to create a GUI seems incredibly roundabout.

4,568,243 | 1 | 4,568,438 | null | 0 | 42 | on various speedtest websites, amongst which site-perf.com I see the `header` causing relatively the largest delay for the website to load. On other speedtest charts i see the same, namely: while connection, ques, resolve, body are all fine, the `header` seems to take oddly long time. A note to be mentioned is that the .jpg files are very tiny thumbnails that are generated by a php script. (look at the size of them: tiny!)
In various trials, for example the two printscreens below that were set two weeks apart, i have more or less the same result: huge yellow bars dwarfing delays caused by other aspects.
Am i interpreting these pictures properly at all? Could the yellow be actually a "polluted" delay where its slow load is due to many factors combined (slow internet connection, slow recolve etc, and not so contrasty to be blaimed at the `headers` in the chart?
if you try to test your own website with similar size/load at [http://site-perf.com](http://site-perf.com), do you get a similar chart as I get?
looking at such results (pictures) what could be causing the relatively higher percentages seen, caused as what is described as `header`?
what could I do/try, to reduce the percentage of time lost in yellow here?

The important parts are that the text should be selectable, lines should wrap and it should be able to handle quite large logs.
The alternatives that I can come up with are:
1. StackPanel inside a ScrollViewer where each line is a row
2. ListView, since that seems more suitable for dynamic content/data binding.
3. Create an own control that does the rendering on its own.

I currently have it(the image scalar type) setup as a binary. From what I have been reading the best way to store the image in the db is a byte[]. So I'm assuming that binary is the way to go. If there is a better way I'd switch.
In my controller I have:
```
//file from client to store in the db
HttpPostedFileBase file = Request.Files[inputTagName];
if (file.ContentLength > 0)
{
keyToAdd.Image = new byte[file.ContentLength];
file.InputStream.Write(keyToAdd.Image, 0, file.ContentLength);
}
```
This builds fine but when I run it I get an exception writing the stream to keyToAdd.Image.
The exception is something like: Method does not exist.
Any ideas?
Note that when using a EF 4.0 model first approach I only have int16, int32, double, string, decimal, binary, byte, DateTime, Double, Single, and SByte as available types.

With `BorderThickness` set to 1, for example, the top-bottom borders between adjacent items are both drawn and therefore appear "thicker" than the side borders, as shown:
The item template that produces these `ListBoxItems` is:
```
<DataTemplate>
<Border BorderThickness="1" BorderBrush="DarkSlateGray" Background="DimGray" Padding="8 4 8 4">
<TextBlock Text="{Binding Name}" FontSize="16"/>

I'm aware that `BorderThickness` can be defined separately for the left/right/top/bottom borders, but this affects the border of the first or last item, as well, which is not desired.

4,572,895 | 1 | 4,572,941 | null | 2 | 533 | OK, I am mostly a LAMP developer so I am new to the entity framework. However, I am familiar with the basics in LINQ and have generated a entity model from my DB. Now here is my requirement:
I have a datagrid on a WinForm that will be refreshed from a data source on a remote server every few seconds as changes to the dataset are made from other sources. Obviously, I'd like to construct a lambda expression to get the right anonymous type to satisfy the columns that needs to be shown in my datagrid. I have done this and here is the result (I'm using a custom datagrid control, btw):
And my code thus far:
```
Models.dataEntities objDB = new Models.dataEntities();
var vans = from v in objDB.vans
select v;
gcVans.DataSource = vans;
```
OK, so now I have my basic data set. One problem I had is that the "Status" column will show a calculated string based on several parameters in the data set. I added this to my entities via a partial class. As you can see in the screenshot, this is working correctly:
```
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace WindowsFormsApplication1.Models {
public partial class van {
public string van_status {
get {
if (this.is_offline == 1) {
return "Offline";
} else if (this.is_prayer_room == 1) {
return "In Prayer Room";
} else {
return "TODO: Create statuses";
}
}
}
}
}
```
This added property works fine. However, the second I try to project the status in an anonymous type so I can also retrieve the school name, I get an error:
```
Models.dataEntities objDB = new Models.dataEntities();
var vans = from v in objDB.vans
select new {
van_name = v.van_name,
school_name = v.school.school_name,
capacity = v.capacity,
phone = v.phone,
van_status = v.van_status
};
gcVans.DataSource = vans;
```
So, I have two questions:
1) If I cannot use computed properties of my partial classes in LINQ projections, how am I supposed to show my computed string in my datagrid?
2) Am I even approaching this correctly? When I resolve #1, how would I refresh this data (ie during a timer fire event)? Would I simply call `objDB.refresh()` and then tell my datagrid to update from the datasource? Does calling that method actually run the lambda expression above or does it load everything from the DB?
Thanks for any assistance with this. Also, if you have any best practices to share that would be awesome! I hope I explained this as thoroughly as you need to provide assistance.

4,573,527 | 1 | 4,575,879 | null | 1 | 2,139 | We have an app written in C++ 6 that fills in blank polygons on a traffic map to show current traffic conditions. Green for good, yellow more congested, etc.
The "shell maps" are bitmaps of the roadways using rectangles and polygons that have nothing filled in them. Data is collected from roadway sensors (wire inductor loops) and the polygons are filled based on loop detector data.
When the maps change, someone has to manually zoom in the bitmap in paint, and get the coordinates around the inside of each new shape, where the congestion color will be filled in. The polygons that make the map skeleton are all drawn in navy blue, on a white background.
I made an app. where when the user clicks anywhere inside the white part of the polygon, the points for the inside perimeter are displayed to the user, with a zoomed in thumbnail showing the inside permiter painted.
In .Net, the perimeter is painted perfectly.
In the C++ 6 app, some of the polyon points my app. collects don't display correctly.
I looked at msPaint, and .Net does not draw the points the same way as MS Paint.
Here's a quick example. Code is from one form with one button and one label. A line is drawn on a bitmap, the bitmap is "zoomed in" so you can see it, and displayed on the label.
The line segment drawn is not the same as the line segment that you draw in MS Paint if you draw a line in Paint using the same two points.

No matter what settings I apply, there is no way to mimic MS Paint in C#, but in C++ 6 mimics MS Paint perfectly.
Is there any type of windows API I can call to draw on an existing bitmap?
Thanks in advance for any replies.

However I cannot locate this in .Net 3.5 or .Net 4.0.
What have I missed? I've included the reference to EntityFramework.dll and I've checked all the attributes under `System.ComponentModel.DataAnnotations` but I cannot locate it.
I have set my project to .Net 4.0 full (not client profile).
Any ideas?

4,574,586 | 1 | 4,594,949 | null | 0 | 1,389 | I have a transparent image which ("hold_empty.png", below) which I want to turn into a button. Inside the button there will be a view with a colored background which is slightly smaller size than the actual image to hold the background color.
The reason for this is because the image has rounded corners and so I cannot simply put a background color on the image as it will appear to be bigger than the image.
The image is a transparent square with "rounded corners". The effect I am trying to create should be like layers.
1. Background color layer (red, green, etc)
2. The "hold_empty.png" picture (above)
3. The whole object (including bg color layer) should be clickable.
The problem I am experiencing is that only the image (and its borders) appears to be clickable, and not the whole object.
The code follows below.
```
// x,y,w,h
CGRect frame = CGRectMake(10, 10, 72, 72);
CGRect frame2 = CGRectMake(5, 5, 60, 60); // I know this is not filling the image, its just a test
UIView *bgColorView = [[UIView alloc] initWithFrame:frame2];
[bgColorView setFrame:frame2];
bgColorView.backgroundColor = [UIColor redColor];
UIImage *image = [UIImage imageWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"hold_empty" ofType:@"png"]];
UIButton *btn = [UIButton buttonWithType:UIButtonTypeCustom];
[btn addSubview:bgColorView];
[btn setImage:image forState:UIControlStateNormal];
btn.frame = frame;
[btn addTarget:self action:@selector(btnSelectColor:) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:btn];
[bgColorView release];
```
So, to summarize: How do I make a transparent image button with a background color clickable?

4,574,712 | 1 | 4,574,808 | null | 0 | 1,992 | I have a small [card game](http://apps.facebook.com/video-preferans/) at Facebook (and few Russian social networks), which gets user's id, first name and avatar through the old REST API.
Now I'm trying to develop the same game as a mobile app with Hero SDK for Android and iPhone. Which means I can't use native SDKs for those platforms, but have to use [OAuth as descibed at Facebook page](http://developers.facebook.com/docs/guides/mobile).
I'm trying to write a short PHP script, which would return the user information as XML to my mobile app. My script can get the token already:
```
<?php
define('FB_API_ID', 'XXX');
define('FB_AUTH_SECRET', 'XXX');
$code = @$_GET['code'];
# this is just a link for me, for development puposes
if (!isset($code)) {
$str = 'https://graph.facebook.com/oauth/authorize?client_id=' . FB_API_ID .
'&redirect_uri=http://preferans.de/facebook/mobile.php&display=touch';
print "<html><body><a href=\"$str\">$str</a></body></html>";
exit();
}
$req = 'https://graph.facebook.com/oauth/access_token?client_id=' . FB_API_ID .
'&redirect_uri=http://preferans.de/facebook/mobile.php&client_secret=' . FB_AUTH_SECRET .
'&code=' . $code;
$ch = curl_init($req);
curl_setopt($ch, CURLOPT_HEADER, FALSE);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
$page = curl_exec($ch);
if (curl_errno($ch))
exit('Download failed');
curl_close($ch);
parse_str($page, $data);
#header('Content-Type: text/xml; charset=utf-8');
#print('<?xml version="1.0"? ><app>');
print_r($data);
#print('</app>');
?>
```
This works well and I get back the token:
```
Array
(
[access_token] => 262578703638|2.OwBuoa2fT5Zp_yo2hFUadA__.3600.1294904800-587287941|ycUNaHVxa_8mvenB9JB1FH3DcAA
[expires] => 6697
)
```
But how can I use this token now to find the user's name and avatar and especially I'm confused by how will I get the current user id?
While using REST API I've always known the current user id by calling `$userid=$fb->require_login()`

```
UPDATE c set OrderID = o1.OrderID
from @Calls c inner join @Orders o1 on c.CallTime > o1.OrderDate
left join @Orders o2 on c.CallTime > o2.OrderDate
and o2.OrderDate > o1.OrderDate

```
and the result of my query is not what I need.
Requirement:
As you can see there are two orders. One is on `2010-12-12` and one is on `2010-12-22`. I want to update `@Calls` table with relevant OrderId with respect to CallTime.
This is sample data so this is not the case that I always have two Orders. There might be 10+ Orders and 100+ calls and 1000s of Customers.

4,574,868 | 1 | 4,600,736 | null | 144 | 70,712 | I have a product with a straightforward REST API so that users of the product can directly integrate with the product's features without using my web user interface.
Recently I have been getting interest from various third parties about integrating their desktop clients with the API to allow users of my product to access their data using that third party application.
I've seen that applications that want to use Twitter authenticate using a login page hosted by Twitter that grants a specific application permission to access that user's data. You click the "Allow" or "Deny" button and the authentication process is complete. Facebook uses the same mechanism as best I can tell.
Upon further research, this seems to be OAuth in action, and seeing as my API is .Net-based, I am thinking I should use DotNetOpenAuth and provide a similar mechanism. Unfortunately the samples are sparsely documented (if at all) and the only tutorials I can find online seem to be focussed on helping you provide a login mechanism for your users so that they can log into your website using a third party provider.
What I would like to do is have my REST API handle all of the core authentication and business logic for my web application and have, under the hood, my web application essentially be another application that just uses the API via OAuth. Users would authenticate on the website either directly using their username and password, or via a third party provider such as MyOpenID or Facebook and then the website would somehow use the returned token to authenticate against the REST API.
It basically looks like I need my API to somehow host an OAuth service, but also have users use a third party OAuth service. I can't help but think I don't quite have enough of a grasp on OAuth to decide if I'm overcomplicating things or if what I'm trying to do is a good or bad way to do things.
Can someone give me at least a broad overview of the steps I need to undertake, or what I should look at to make this happen? Or point me at some tutorials? Or blast my proposal and tell me I'm going about this (architecturally) all wrong?

I'd like the button to be about half its current width, centered in the column.

4,575,230 | 1 | 4,579,547 | null | 4 | 1,138 | I'm using SQL Server 2008. I have a table with over 3 million records, which is related to another table with a million records.
I have spent a few days experimenting with different ways of querying these tables. I have it down to two radically different queries, both of which take 6s to execute on my laptop.
The first query uses a brute force method of evaluating matches, and removes incorrect matches via aggregate summation calculations.
The second gets all possibly likely matches, then removes incorrect matches via an EXCEPT query that uses two dedicated indexes to find the low and high mismatches.
Logically, one would expect the brute force to be slow and the indexes one to be fast. Not so. And I have experimented heavily with indexes until I got the best speed.
Further, the brute force query doesn't require as many indexes, which means that technically it would yield better overall system performance.
Below are the two execution plans. If you can't see them, please let me know and I'll re-post then in landscape orientation / mail them to you.
Brute-force query:
```
SELECT ProductID, [Rank]
FROM (
SELECT p.ProductID, ptr.[Rank], SUM(CASE
WHEN p.ParamLo < si.LowMin OR
p.ParamHi > si.HiMax THEN 1
ELSE 0
END) AS Fail
FROM dbo.SearchItemsGet(@SearchID, NULL) AS si
JOIN dbo.ProductDefs AS pd
ON pd.ParamTypeID = si.ParamTypeID
JOIN dbo.Params AS p
ON p.ProductDefID = pd.ProductDefID
JOIN dbo.ProductTypesResultsGet(@SearchID) AS ptr
ON ptr.ProductTypeID = pd.ProductTypeID
WHERE si.Mode IN (1, 2)
GROUP BY p.ProductID, ptr.[Rank]
) AS t
WHERE t.Fail = 0
```
Index-based exception query:
```
with si AS (
SELECT DISTINCT pd.ProductDefID, si.LowMin, si.HiMax
FROM dbo.SearchItemsGet(@SearchID, NULL) AS si
JOIN dbo.ProductDefs AS pd
ON pd.ParamTypeID = si.ParamTypeID
JOIN dbo.ProductTypesResultsGet(@SearchID) AS ptr
ON ptr.ProductTypeID = pd.ProductTypeID
WHERE si.Mode IN (1, 2)
)
SELECT p.ProductID
FROM dbo.Params AS p
JOIN si
ON si.ProductDefID = p.ProductDefID
EXCEPT
SELECT p.ProductID
FROM dbo.Params AS p
JOIN si
ON si.ProductDefID = p.ProductDefID
WHERE p.ParamLo < si.LowMin OR p.ParamHi > si.HiMax
```
My question is, based on the execution plans, which one look more efficient? I realize that thing may change as my data grows.
I have updated the indexes, and now have the following execution plan for the second query:

4,576,493 | 1 | 4,576,721 | null | 25 | 30,394 | The Android game [My Paper Plane](http://www.appbrain.com/app/my-paper-plane-2-%283d%29/com.wavecade.mypaperplane_x) is a great example of how to implement tilt controls, but I've been struggling to understand how I can do something similar.
I have the following example that uses [getOrientation()](http://developer.android.com/reference/android/hardware/SensorManager.html) from the SensorManager. The whole thing is on [pastebin here](http://pastebin.com/c1MNT5x7). It just prints the orientation values to text fields. Here is the most relevant snippet:
```
private void computeOrientation() {
if (SensorManager.getRotationMatrix(m_rotationMatrix, null,
m_lastMagFields, m_lastAccels)) {
SensorManager.getOrientation(m_rotationMatrix, m_orientation);
/* 1 radian = 57.2957795 degrees */
/* [0] : yaw, rotation around z axis
* [1] : pitch, rotation around x axis
* [2] : roll, rotation around y axis */
float yaw = m_orientation[0] * 57.2957795f;
float pitch = m_orientation[1] * 57.2957795f;
float roll = m_orientation[2] * 57.2957795f;
/* append returns an average of the last 10 values */
m_lastYaw = m_filters[0].append(yaw);
m_lastPitch = m_filters[1].append(pitch);
m_lastRoll = m_filters[2].append(roll);
TextView rt = (TextView) findViewById(R.id.roll);
TextView pt = (TextView) findViewById(R.id.pitch);
TextView yt = (TextView) findViewById(R.id.yaw);
yt.setText("azi z: " + m_lastYaw);
pt.setText("pitch x: " + m_lastPitch);
rt.setText("roll y: " + m_lastRoll);
}
}
```
The problem is that the values this spits out look like nonsense, or at least there's no way to isolate which type of motion the user performed. I've drawn a diagram to indicate the 2 types of motion that I'd like to detect - 1. "tilt" for pitch and 2. "rotate" for roll/steering:
(That's an isometric-ish view of a phone in landscape mode, of course)
When I tilt the phone forwards and backwards along its long axis - shown by 1. - I expected only 1 of the values to change much, but all of them seem to change drastically. Similarly, if I rotate the phone about an imaginary line that comes out of the screen - shown in 2. - I'd hope that only the roll value changes, but all the values change a lot.
The problem is when I calibrate my game - which means recording the current values of the angles x, y and z - I later don't know how to interpret incoming updated angles to say "ok, looks like you have tilted the phone and you want to roll 3 degrees left". It's more like "ok, you've moved the phone and you're a-tiltin' and a-rollin' at the same time", even if the intent was only a roll. Make sense?
Any ideas? I've tried using remapCoordinateSystem to see if changing the axis has any effect. No joy. I think I'm missing something fundamental with this :-(

$sql = 'UPDATE ' . $tbl_name . ' SET `Name` = \'' . $name .'\', `Store` = \'apples\', `URL` = \'apples\', `SKU` = \'apples\', `Price` = \'apples\', `Location` = \'apples\' WHERE CONVERT(`crisss1205_me_com`.`ID` USING utf8) = \'1\' LIMIT 1;';
```
and it doesn't return any errors. The variable is coming from a $_POST
If I print out the query using `echo $sql;` it looks like this:
> UPDATE crisss1205_me_com SET `Name` = 'HelloWorld', `Store` = 'apples', `URL` = 'apples', `SKU` = 'apples', `Price` = 'apples', `Location` = 'apples' WHERE CONVERT(`crisss1205_me_com`.`ID` USING utf8) = '1' LIMIT 1;
But in the database under the "Name" column it shows a blank space.
If I leave the query alone but change `$name = $_POST['name'];` to `$name = "HelloWorld";` it will update the database fine.
What could be the reason why it will not show up from a "POST"?

```
<?php
$tbl_name = $_COOKIE['e-mail_ctt'];
require_once('../config.php');
$name = (string)$_POST['name'];
$store = $_POST['store'];

$price = $_POST['price'];

The problem is the data displayed in JSP view is not as expected. The problem didn't happen at the first time I tested this a month ago using sample data. Now using real time data with more than 150.000 records, the view is messed up.

passed=1, failed=0
JSP View:
I've checked in Firebugs that the response given in json is the data with incorrect date.
I've tested this using IE7, IE8, FF3.6, Chrome8 with same result.
Does anyone have similar problem before? What is the solution?

dir = dir/dist;
vec4 color = texture2D(tex,uv);
vec4 sum = color;
for (int i = 0; i < 10; i++)
sum += texture2D( tex, uv + dir * samples[i] * sampleDist );
sum *= 1.0/11.0;
float t = dist * sampleStrength;
t = clamp( t ,0.0,1.0);

4,579,359 | 1 | null | null | 2 | 834 | I've been using CutyCapt to take screen shots of several web pages with great success. My challenge now is to paint a few dots on those screen shots that represent where a user clicked.
CutyCapt goes through a process of resizing the web page to the scroll width before taking a screen shot. That's extremely useful because you only get content and not much (if any) of the page's background.
My challenge is trying to map a user's mouse X coordinates to the screen shot. Obviously users have different screen resolutions and have their browser window open to different sizes. The image below shows 3 examples with the same logo. Assume, for example, that the logo is 10 pixels to the left edge of the "content" area (in red).
In each of these cases, and for any resolution, I need a JavaScript routine that will calculate that the logo's X coordinate is 10. Again, the challenge (I think) is differing resolutions. In the center-aligned examples, the logo's position, as measured from the left edge of the browser (in black), differs with changing browser size. The left-aligned example should be simple as the logo never moves as the screen resizes.
Can anyone think of a way to calculate the scrollable width of a page? In other words, I'm looking for a JavaScript solution to calculate the minimum width of the browser window before a horizontal scroll bar shows up. And I need to do this without first knowing any element IDs or class names.
Thanks for your help!

The reason I ask this is I previously posted a question ([link](https://stackoverflow.com/questions/4575230/two-radically-different-queries-against-4-mil-records-execute-in-the-same-time/4576303#4576303)) in which two queries performed at the same speed, yet one didn't attempt to use the index on the processed columns. After SQL Server suggested I put a that the columns being queried (it suggested this for both queries), I started looking for reasons as to why it would make such a strange suggestion.
I experimented with making the indexes covering and composite, but both executed in the same time (we're talking 3 million rows).
Finally I concluded it was because of the ultra-high cardinality of the data. Every row is unique. I am deducing this caused SQL server to choose an index scan. However, the query stated "WHERE Col1 > ? AND Col2 < ?", so this is a little confusing.
My questions are:
1. At what cardinality will a RDBMS always opt for an index scan?
2. Can anyone explain why SQL Server would not use the index when the WHERE statement would indicate this would make sense?
I have attached the execution plan.

4,580,344 | 1 | 4,580,369 | null | 0 | 177 | I am trying to use JSON for getting dynamic content to my webpage, using javascript. Something is not correct and I have problem figuring out what it can be. In firebug I can see that the JSON-data is retreived as it should. When looking in Firebug under "DOM", the URL I am accessing for the page (the actual page I have created, not the URL to JSON-data) is coloured red (see screenshot below). Here is my javascript:
```
$(document).ready(function() {
$('#target').click(function() {
alert("At least I',m reached ");
$.getJSON('http://localhost/timereporting/phpscriptlibrary/get_remaining_hours.php', function(data) {
document.getElementById('errorDiv').innerHTML = "Divtext";
alert("Inside getJason");
});
alert("At least I',m done ");
});
```
This is the significant part of my php file:
```
$json_string = "{\"activities\": ";
$json_string = $json_string."[";
for ( $counter = 0; $counter < $num; $counter += 1) {
$json_string = $json_string."[".mysql_result($rows,$counter,'date').", \"".mysql_result($rows,$counter,'activity_id')."\", ".mysql_result($rows,$counter,'hours')."]";
if($counter != ($num-1)){
$json_string = $json_string.", ";
}
}
$json_string = $json_string."]}";
echo $json_string;
```
I assume that "echo" is the way to "send" the JSON-data to the javascript?
One strange thing is that in firebug the JSON-data is presented in two different ways. If you look at the included screenshots below, the second one has dates like "1988" or similar while on the first one the dates are more complete like "2010-12-10". The first screenshot depicts how it should be and that's how I am trying to send it, and obviously it is received like this at some point.
How come my div-tag isn't updated with the date or that the alert inside the $.getJSON isn't triggered, only the alert before and after?

4,580,510 | 1 | 4,580,568 | null | 1 | 387 | In my app I'm using a spinners to let the user select an item from a list. Everything works fine but I'm not really happy with the look of the spinner. As you can see in the image below it has the same design as a normal button.
What I want is a spinner which looks more like a normal text field. So I browsed a little bit through the drawable folder of the Android sources and found out that the spinner background should normally look quite different. I append an image of a spinner with the background image as I found it in the drawable folder. Although the spinner in the image is focused, I think you can see the difference between both spinners.
Now I'm wondering why the my spinner (first one) doesn't have the same design as the second one as II didn't changed any attributes which are related to the design of it. Where does this button like design come from?

4,580,834 | 1 | 4,581,238 | null | 6 | 4,040 | I'm making a Minecraft clone as my very first OpenGL project and am stuck at the box selection part. What would be the best method to make a reliable box selection?
I've been going through some AABB algorithms, but none of them explain well enough what they exactly do (especially the super tweaked ones) and I don't want to use stuff I don't understand.
Since the world is composed of cubes I used octrees to remove some strain on ray cast calculations, basically the only thing I need is this function:
```
float cube_intersect(Vector ray, Vector origin, Vector min, Vector max)
{
//???
}
```
The ray and origin are easily obtained with
```
Vector ray, origin, point_far;
double mx, my, mz;
gluUnProject(viewport[2]/2, viewport[3]/2, 1.0, (double*)modelview, (double*)projection, viewport, &mx, &my, &mz);
point_far = Vector(mx, my, mz);
gluUnProject(viewport[2]/2, viewport[3]/2, 0.0, (double*)modelview, (double*)projection, viewport, &mx, &my, &mz);
origin = Vector(mx, my, mz);
ray = point_far-origin;
```
min and max are the opposite corners of a cube.
I'm not even sure this is the right way to do this, considering the number of cubes I'd have to check, even with octrees.
I've also tried `gluProject`, it works, but is very unreliable and doesn't give me the selected face of the cube.
---
So this is what I've done: calculate a position in space with the ray:
```
float t = 0;
for(int i=0; i<10; i++)
{
Vector p = ray*t+origin;
while(visible octree)
{
if(p inside octree)
{
// then call recursive function until a cube is found
break;
}
octree = octree->next;
}
if(found a cube)
{
break;
}
t += .5;
}
```
It's actually surprisingly fast and stops after the first found cube.
As you can see the ray has to go trough multiple octrees before it finds a cube (actually a position in space) - there is a crosshair in the middle of the screen. The lower the increment step the more precise the selection, but also slower.
