1,390,460 | 1 | 1,465,229 | null | 2 | 1,239 | I have this Win32 user-drawn tab control that is created as:
```
CONTROL "Tab1",IDC_TAB_CONT,"SysTabControl32",TCS_BOTTOM |
TCS_OWNERDRAWFIXED | NOT WS_VISIBLE,0,14,185,88
```
I'd like for this control to have its tabs resize as never to have to see the "":
Now, pretty much everything about this control works as expected, except for that fact that it won't respond to `TabCtrl_SetItemSize`. Try as I may, the size I get for the tabs when I get to draw them (in the `DRAWITEMSTRUCT` passed to `WM_DRAWITEM`) is always the size that fits the longest caption in them and never the size I've set with `TabCtrl_SetItemSize`.
However, in the [TabCtrl_SetItemSize documentation](http://msdn.microsoft.com/en-us/library/bb760694(VS.85).aspx), it says that:
> [`TabCtrl_SetItemSize`] sets the width and height of tabs in a
fixed-width or
control.
The only way I've managed to have a decent resizing is by setting a dummy string of the desired length in it by sending the control a `TCM_SETITEM` message, and writing the desired text in it at draw time. This is rather inconvenient and not a particularly nice hack.
Is there anybody who would know
1. Why TabCtrl_SetItemSize isn't working as expected? and/or
2. How to set the tab size properly?
Many thanks,
joce.

1,391,718 | 1 | 1,392,711 | null | 3 | 5,727 | I have a simple page that returns an ajax success/error message on submission. The form is submitted using a standard ASP.Net linkbutton.
My Selenium test correctly clicks the linkbutton, however the click event times out and fails. The rest of the testcase conditions pass (as selenium is successfully clicking the link and the ajax success message is displayed).
All I can think is that for some reason click() is calling waitForPageToLoad which is why it is timing out. Is there any way to suppress this, or am I barking up the wrong tree?
Is there an alternative way to handle the click that doesn't care what happens after the event fires?
More Info: Selenium IDE 1.0.2 hosted in Firefox 3.5.2 on Vista (don't ask)
---
I've managed to get my test to pass by creating my own click() function in user-extensions.js that does call . While my test does pass now, this is not really an ideal solution.
If you'd like to try this yourself, add the following to user-extensions.js (make sure you are referencing this file in your Se:IDE configuration via Tools | Selenium IDE | Options | Options | General | Selenium Core extensions)
```
Selenium.prototype.doBeatnicClick = function(locator) {
/**
* Clicks on a link, button, checkbox or radio button.
* Hacky workaround for timeout problem with linkbutton.
* Suspect there is an issue with Selenium.decorateFunctionWithTimeout()
*/
var element = this.browserbot.findElement(locator);
var elementWithHref = getAncestorOrSelfWithJavascriptHref(element);
if (browserVersion.isChrome && elementWithHref != null) {
var win = elementWithHref.ownerDocument.defaultView;
var originalLocation = win.location.href;
var originalHref = elementWithHref.href;
elementWithHref.href = 'javascript:try { '
+ originalHref.replace(/^\s*javascript:/i, "")
+ ' } finally { window._executingJavascriptHref = undefined; }';
win._executingJavascriptHref = true;
this.browserbot.clickElement(element);
}
this.browserbot.clickElement(element);
```
};
Reload Se:IDE and you'll have access to a new command, beatnicClick() which should work where you're experiencing a click() timeout.
Hopefully this will be patched, or fixed in the next release of Se:IDE.

1,392,429 | 1 | 1,427,604 | null | 5 | 2,705 | Image the following situation:
1. You're on Windows XP (even though the dialog shown below is a Vista screenshot).
2. You have two physical USB game controllers, let's call them A and B.
3. You have a piece of software that apparently accesses joysticks in a legacy way, only recognizing and allowing use of one single joystick.
4. When using this software, you want to use both controllers together, for instance: use the left thumbstick from A and the right thumbstick from B use buttons #1, #2 and #6 from A and buttons #2 and #8 from B
I guess this problem must have already popped up in hardcore gaming somewhere, and a kind of "virtual game controller driver" or other piece of software for this is available. This would ideally show up as a game controller in Windows and allow a virtual setup as described above using any inputs available on physically connected controllers to create a compound virtual one.
If this is the case, I'd love to hear where to get my hands on this. And if not, any pointers on trying to get this going are welcome. I guess I'd have to read up on DirectInput and dust off my next to non-existent C++ skills then?
Like Runeborg answered, it now looks like I might have to get cracking at trying to write my own "virtual game controller device driver" if I want this to happen. :-(
Quick update: [have asked same question on smartgamer](http://smartergamer.stackexchange.com/questions/161/how-to-mix-and-match-inputs-from-two-game-controllers-into-one-virtual-controll) in the hope another crowd there might come up with an existing answer.

1,395,476 | 1 | 1,395,530 | null | 0 | 1,518 | Okay, so I'm looking at a typical color chooser and it looks something like this:
If we deal with only highly saturated colors, the blending pattern behaves like this:
```
R 255
G 0
B 0
R 255
G 0 -> 255
B 0
R 255
G 255
B 0
R 255 -> 0
G 255
B 0
R 0
G 255
B 0
R 0
G 255
B 0 -> 255
R 0
G 255
B 255
R 0
G 255 -> 0
B 255
R 0
G 0
B 255
R 0 -> 255
G 0
B 255
R 255
G 0
B 255
R 255
G 0
B 255 -> 0
R 255
G 0
B 0
```
Is it possible to define an interpolating function f which takes a value from 0 to 1 and produces a color on this spectrum (where 0 and 1 correspond to the left and right hand sides of the spectrum posted above)? I only care about highly saturated colors (One component is always 255.). Also, I notice that this pattern blends from R to G to B. However, is there also a similar function which blends between cyan, magenta, and yellow? And while this is not correct, if f(0) produced cyan and f(1) produced yellow, then f(0.5) would produce a green color similar to the one you might achieve if you mixed two paints.
I hope this makes sense. Please feel free to have me clarify anything. Thanks!

1,395,513 | 1 | 3,806,314 | null | 19 | 34,665 | The 8-puzzle is a square board with 9 positions, filled by 8 numbered tiles and one gap. At any point, a tile adjacent to the gap can be moved into the gap, creating a new gap position. In other words the gap can be swapped with an adjacent (horizontally and vertically) tile. The objective in the game is to begin with an arbitrary configuration of tiles, and move them so as to get the numbered tiles arranged in ascending order either running around the perimeter of the board or ordered from left to right, with 1 in the top left-hand position.
I was wondering what approach will be efficient to solve this problem?

(Note that this diagram has high addresses at the bottom and low addresses at the top.)
Could anyone explain me what `ebp` and `esp` are in this context?
From what I see, I'd say the stack pointer points always to the top of the stack, and the base pointer to the beginning of the the current function? Or what?

edit: I mean this in the context of windows programs
`eip`
I have the following code from MSVC++:
```
var_C= dword ptr -0Ch
var_8= dword ptr -8
var_4= dword ptr -4
hInstance= dword ptr 8
hPrevInstance= dword ptr 0Ch
lpCmdLine= dword ptr 10h
nShowCmd= dword ptr 14h
```
All of them seem to be dwords, thus taking 4 bytes each. So I can see there is a gap from hInstance to var_4 of 4 bytes. What are they? I assume it is the return address, as can be seen in wikipedia's picture?
---
(editor's note: removed a long quote from Michael's answer, which doesn't belong in the question, but a followup question was edited in):
This is because the flow of the function call is:
```
* Push parameters (hInstance, etc.)
* Call function, which pushes return address
* Push ebp
* Allocate space for locals
```

I'm going to start studying/coding at the local university's library. Since I'm not a student, I won't be able to utilize their wireless internet access. Since StackOverflow is such a great resource, I want to be able to take it with me, so I'm building a small desktop application to load/search/display the most recent data dumps.
I want to display code blocks in the same sort of rectangular block as this site does, so I played with the RichTextBox control to try to create this effect. Unfortunately, the RichTextBox.SelectedBackColor property only colors the actual text, when what I want is a rectangle reaching to the outer limits of the selection.
This is what I am able to produce with the RichTextBox:

$("#ulworksites li input:checkbox").each(function() {

$(this).attr('checked', $("#ckbSelectAll").attr('checked'));
// Fire onWorksiteChecked method here
// > as suggested by August Lilleaas in his answer
$(this).click(); // <-- when this executes I still have the input box to be unchecked, the line above is not perform

$(this).attr('checked');

how can I execute that function?

1,401,311 | 1 | null | null | 3 | 2,528 | If you go to the following link you'll see a really cool Javascript simulation of a cube that rotates based on your mouse position.
Simulation: [here.](http://maettig.com/code/javascript/3d_dots.html)
If you view the source of the cube rotating script you'll see:
```
<script type="text/javascript">
/* I wrote this script in a few minutes just for fun. It's not made to win any
competition. */
var dimension = 1, a = 0, b = 0, i = 27;
while (i--) document.write('<b id="l' + i + '">+</b>');
function f()
{
i = 0;
for (x = -dimension; x <= dimension; x += dimension)
for (y = -dimension; y <= dimension; y += dimension)
for (z = -dimension; z <= dimension; z += dimension)
{
u = x;
v = y;
w = z;
u2 = u * Math.cos(a) - v * Math.sin(a);
v2 = u * Math.sin(a) + v * Math.cos(a);
w2 = w;
u = u2; v = v2; w = w2;
u2 = u;
v2 = v * Math.cos(b) - w * Math.sin(b);
w2 = v * Math.sin(b) + w * Math.cos(b);
u = u2; v = v2; w = w2;
var c = Math.round((w + 2) * 70);
if (c < 0) c = 0;
if (c > 255) c = 255;
s = document.getElementById('l' + i).style;
s.left = 300 + u * (w + 2) * 50;
s.top = 300 + v * (w + 2) * 50;
s.color = 'rgb(' + c + ', ' + c + ', 0)';
s.fontSize = (w + 2) * 16 + 'px';
/* The Digg users missed depth sort, so here it is. */
s.zIndex = Math.round((w + 2) * 10);
i++;
}
}
/* Using a timer instead of the onmousemove handler wastes CPU time but makes
the animation much smoother. */
setInterval('f()', 17);
</script>
```
I've looked over it several times, and I still don't understand how the points for the cube are calculated. Is this using "Euler Rotations"? One of the big problems I've had is the use of single letter variable names that mean nothing to me.
Would anyone with the requisite math knowledge help explain how the math works behind rotating the cube in this simulation? I'd like to make similar things but when it comes to calculating the points positions, I'm a little lost.

1,408,104 | 1 | 1,408,147 | null | 1 | 461 | Imagine you are drawing a map of county borders. You are given a set of polygons, one for each boundary, and you draw each polygon.
In places where two counties share a border you just end up drawing the border twice. In the absence of partial transparency effects, and with a solid pen, this is no problem.
But, on maps, borders of this kind are customarily shown by dash-dotted lines. In this case, situations like the one depicted below can happen:
Notice how the dash pattern, which normally is dash-dot-dot, gets screwed up where the two areas share a border. In this case, it happened to become a longdash-dot pattern, but in general it could do anything from coincidentally looking normal to creating a solid line.
How does/should map rendering software prevent artifacts of this kind from occuring?

1,409,097 | 1 | 1,609,098 | null | 6 | 1,406 | I'm trying to enable PerlCritic support in Komodo.
The official word from ActiveState, the makers of Komodo IDE 5.1 (Win 32) is:
"To enable PerlCritic support, please install the 'Perl-Critic' and 'criticism' modules."
Well, installing Perl-Critic was a piece of cake:
```
ppm install Bundle-Perl-Critic
```
However, I've search every repository in PPM4, (trouchelle and the usual suspects) and they don't seem to have the module called 'criticism'. I've installed lots of modules using CPAN and PPM, but this module proves to be the most elusive so far. Am I missing something here?

1,414,224 | 1 | 1,492,680 | null | 0 | 2,444 | I've got an iPhone app that I'm working on that uses Push Notifications.
In the payload I'm specifying a few things:
- - -
The notification is getting to my iPhone just fine. It shows a message without buttons. So body and action-loc-key are working just fine. But, it's not playing any sound.
However, there are a couple of things I've noticed during troubleshooting:
1. if I implement application:didReceiveRemoteNotification, everything looks fine. The Dictionary argument contains a key for sound, whose value is indeed the name of the file I want to play.
2. The sound file itself "works" because if I play it inside of the app (using the SoundEffect class from the BubbleLevel sample) it works just fine.
Despite these two facts, the sound effect simply isn't playing.
In the settings app, everything looks right - Push is turned on for my app, and I have both "sounds" and "alerts" set to on as well.
The iPhone documentation center suggests using Quicktime to look at the format of the file. This is what it looks like.
Finally, if I look at the info for this file in XCode, it says the file type is simply the default, "file." From what I could tell there is no audio-caf option in the list. I tried audio-WAV (the sound engineer told me the original files were WAVs) but that didn't change anything.
In addition, the code:
```
- (void)applicationDidFinishLaunching:(UIApplication *)application {
// view controller set up stuff
// ...
[[UIApplication sharedApplication] registerForRemoteNotificationTypes:(UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeSound)];

My goal is to create something that does the classic windows behaviors of open, save, new as well as reflecting the name of the saved file in the title bar. Also, when there are unsaved changes, the title bar should include an *.
So I created a view & a presenter that manage the application's persistence state. One improvement I've considered is breaking out the text handling code so the view/presenter is truly a single-purpose entity.

1,422,602 | 1 | 1,422,875 | null | 0 | 2,206 | I have written a function that positions a tooltip just above a textbox.
The function takes two arguments:
- - The ID of the textbox above which the tooltip will appear.- - - The ID of the tooltip which will appear above the textbox.-
```
function positionTooltip(textBoxId, toolTipId){
var hoverElementOffsetLeft = $(textBoxId).offset().left;
var hoverElementOffsetWidth = $(textBoxId)[0].offsetWidth;
var toolTipElementOffsetLeft = $(toolTipId).offset().left;
var toolTipElementOffsetWidth = $(toolTipId)[0].offsetWidth;
// calcluate the x coordinate of the center of the hover element.
var hoverElementCenterX =
hoverElementOffsetLeft + (hoverElementOffsetWidth / 2);
// calculate half the width of the toolTipElement
var toolTipElementHalfWidth = toolTipElementOffsetWidth / 2;
var toolTipElementLeft = hoverElementCenterX - toolTipElementHalfWidth;
$(toolTipId)[0].style.left = toolTipElementLeft + "px";
var toolTipElementHeight = $(toolTipId)[0].offsetHeight;
var hoverElementOffsetTop = $(textBoxId).offset().top;
var toolTipYCoord = hoverElementOffsetTop - toolTipElementHeight;
toolTipYCoord = toolTipYCoord - 10;
$(toolTipId)[0].style.top = toolTipYCoord + "px";
$(toolTipId).hide();
$(textBoxId).hover(
function(){ $(toolTipId + ':hidden').fadeIn(); },
function(){ $(toolTipId + ':visible').fadeOut(); }
);
$(textBoxId).focus (
function(){ $(toolTipId + ':hidden').fadeIn(); }
);
$(textBoxId).blur (
function(){ $(toolTipId+ ':visible').fadeOut(); }
);
}
```
---
The function works fine upon initial page load:
---
However, after the user resizes the window the tooltips move to locations that no longer display above their associated textbox.
---
I've tried writing some code to fix the problem by calling the positionTooltip() function when the window is resized but for some reason the tooltips do not get repositioned as they did when the page loaded:
```
var _resize_timer = null;
$(window).resize(function() {
if (_resize_timer) {clearTimeout(_resize_timer);}
_resize_timer = setTimeout(function(){
positionTooltip('#textBoxA', ('#toolTipA'));
}, 1000);
});
```
I'm really at a loss here as to why it doesn't reposition the tooltip correctly as it did when the page was initially loaded after a resize.

1,424,189 | 1 | 1,424,274 | null | 6 | 2,933 | I'm using ggplot2 to make some bullseye charts in R. They look delightful, and everyone is very pleased - except that they'd like to have the values of the bullseye layers plotted on the chart. I'd be happy just to put them in the lower-right corner of the plot, or even in the plot margins, but I'm having some difficulty doing this.
Here's the example data again:
```
critters <- structure(list(Zoo = "Omaha", Animals = 50, Bears = 10, PolarBears = 3), .Names = c("Zoo",
"Animals", "Bears", "PolarBears"), row.names = c(NA, -1L), class = "data.frame")
```
And how to plot it:
```
d <- data.frame(animal=factor(c(rep("Animals", critters$Animals),
rep("Bears", critters$Bears), rep("PolarBears", critters$PolarBears)),
levels = c("PolarBears", "Bears", "Animals"), ordered= TRUE))
grr <- ggplot(d, aes(x = factor(1), fill = factor(animal))) + geom_bar() +
coord_polar() + labs(x = NULL, fill = NULL) +
scale_fill_manual(values = c("firebrick2", "yellow2", "green3")) +
opts(title = paste("Animals, Bears and Polar Bears:\nOmaha Zoo", sep=""))
```
I'd like to add a list to, say, the lower right corner of this plot saying,
```
Animals: 50
Bears: 10
PolarBears: 3
```
But I can't figure out how. My efforts so far with `annotate()` have been thwarted, in part by the polar coordinates. If I have to add the numbers to the title, so be it - but I always hold out hope for a more elegant solution.
EDIT:
An important note for those who come after: the bullseye is a bar plot mapped to polar coordinates. The ggplot2 default for bar plots is, sensibly, to stack them. However, that means that the rings of your bullseye will also be stacked (e.g. the radius in my example equals the sum of all three groups, 63, instead of the size of the largest group, 50). I think that's what most people expect from a bullseye plot, especially when the groups are nested. Using `geom_bar(position = position_identity())` will turn the stacked rings into layered circles.

1,429,810 | 1 | 1,504,130 | null | 0 | 1,531 | I have a setup where I am using amcharts that is feed data via appendData from an AJAX call. The call goes to a URL which simply renders the Time.now as the X and 8 lines using the function 2cos(x/2)+2ln (ln is the line number). AJAX request is made every 1 second.
The backend is always correct and always returns a single point, unless it is a duplicate X in which it throws an error. The error causes not to complete and therefore not call appendData.
Anybody have any idea what is going wrong with amcharts? It seems to be an issue only with appendData (which I need to simulate a sliding window).

1,434,306 | 1 | 1,682,317 | null | 0 | 2,218 | I have a customer who is currently using Excel to do their staff planning. They have many workbooks for different projects and each project contains 1 or more sheets containing the actual staffing data:
The customer wants to consolidate all of the data from all of these many sheets and workbooks into a single pivot table. A 'consolidated' pivot is not an option because they want to be able to mess with all of the (non-date) fields in the source data. They don't want to be limited to only 'Row' and 'Column'. My current solution is a macro that consolidates all of the data within a workbook through a fairly convoluted copy and rotate process. I copy a row of 'meta data' (everything that's not a date) first, then I copy / transpose the dates for the meta data row into a single 'Date' column. Then I extend the meta data so that the same data is defined for each date.
I have a separate workbook that grabs the consolidated sheet from each workbook and builds a single pivot table from them.
It works, but it's pretty inefficient, since the total number of tasks / assignments number in the many thousands. In my dreams, I would love to eliminate the consolidation step completely, but I don't see that happening. A more efficient consolidation approach is about the best I'm hoping for at this point.
If anyone has some 'outside the box' ideas, I'm all ears!
The solutions needs to work on windows XP, Office 2002 and 2003.

OK, so it's been a little while since I first posted this question. It seems to me that many of the initial responders failed to really get what I was saying--a common response was some variation on "What you're saying doesn't make any sense"--and so I've made some handy diagrams to really illustrate my point.
When we speak of numbers, we are generally referring to points on what grade school children learn is called the Number Line:
Now, when we learn arithmetic, our minds learn to perform a very interesting transformation of this concept. Evalutating the expression `1 + 0.5`, for example, if we simply applied our "number line thinking", would require us to somehow make sense of this:
It's difficult to really illustrate that, because it's difficult to about that: "adding" two points. This is where a lot of responders struggled with the idea of adding dates (or simply dismissed it as absurd), because they were thinking of dates as points.
However, the expression `1 + 0.5` make sense to us, because when we think of it, we're really imagining this:
That is, the (or ) 1, plus the [vector](http://en.wikipedia.org/wiki/Euclidean_vector) 0.5, resulting in 1.5.
Alternately, we may be imagining this:
That is, the 1, plus the 0.5, resulting in the 1.5.
In other words, when dealing with numbers, we treat points and vectors interchangeably. But what about dates? Dates are, after all, basically numbers. If you don't believe me, compare this line to the number line above:
Notice the correspondence between the timeline and the number line? This was my point: if we perform the transformation above with , we ought to be able to do it with dates as well. So, applying "timeline thinking", the expression `0001-Jan-02 00:00:00 + 0001-Jan-01 12:00:00` doesn't make a lot of sense, as plenty of responders pointed out:
, if we do the same conceptual transformation in our head that we perform , we can easily "rethink" the above as this:
So clearly, the difference between a `DateTime` and a `TimeSpan` is the same difference that exists between a point and a vector. What I think caused a lot of people to respond negatively to my suggestion is that it just feels so unnatural to think of dates as magnitudes in this way. But I don't buy the argument that there's no obvious reference point to use as zero.
Don't get me wrong: I'm not questioning the of drawing a conceptual divide between the notion of a `DateTime` and a `TimeSpan`. Really, my question all along should have been (as ChrisW indirectly suggested), why we treat numbers and vectors interchangeably when dealing with regular numeric types? (Or: why do we have just one `int` type, instead of `int` and `intspan`?) There's a big difference, and yet we don't ever really think about it until sometime in junior high or high school, when we begin geometry. And then it's treated as this new mathematical concept, when in reality it's something we've been utilizing ever since we learned to add numbers by counting with our fingers.
In the end, the best answer came from Strilanc, who pointed out that the use of `DateTime` and `TimeSpan` is really an implementation of an [affine space](http://en.wikipedia.org/wiki/Affine_space), which has the convenient property of not needing a reference point to treat as the origin. So thanks, Strilanc. I'm giving the accepted answer to ChrisW, however, for being the first one to bring up the concept of vectors and points, which really got to the crux of the matter.
---
I am certainly no programming jack of all trades, but I know both PHP and .NET have a `TimeSpan` class in addition to a `DateTime` class (or structure in .NET), and I am guessing this is the case in a variety of other languages and frameworks as well (though I am writing this primarily with reference to the .NET structures). This might seem a strange question, but isn't `TimeSpan` redundant?
In case you think the answer is obvious ("A `DateTime` is an absolute point in time, while a `TimeSpan` is a range of time -- simple as that!"), consider this: an integer can be conceptualized as either an absolute value (the point on the number line) or a distance values--and we don't need two separate data types for these different conceptualizations. I can still write 5 + 6 without any ambiguity as to what I mean.
As long as there is a consistent zero-point reference, it seems to me there should be no reason why one would need a `TimeSpan` object to perform arithmetic operations on `DateTime` objects, or to get the distance between them.
What am I missing? Why can't the unique methods and properties of the `TimeSpan` structure simply be folded into `DateTime`?
(Disclaimer: It isn't like I'm passionate about this or anything; I'm fine using `DateTime` and `TimeSpan` objects as they're intended all the time. I'm just asking a question.)
: Okay, over-simplified example to illustrate my point:
Consider the equation 10 - 5 = 5. One could read this as "Start at 10 (value), move 5 to the left (span), and you end up at 5 (value)."
Suppose, just to make things easy, we let January 1 1900 be point zero and we define `TimeSpan` objects in terms of days only.
Then 10 - 5 = 5 could be understood, in `DateTime` terms, as January 11 1900 - January 6 1900 = January 6 1900. . The fact that we are viewing the 10 as a , the first 5 as a , and the last 5 as a again is merely for our own conceptual benefit. My point is just this: that the only difference is in how you think of the number, not in what it actually is. This is why we don't have separate structures for, say, integer values and integer spans -- a plain old integer covers all our bases.
Am I making any sense?

Each of my property objects contains a definition of the kind of cell it wants to display as. But at the same time, I'd like to use bindings so that values are automatically updated as they can be changed elsewhere.
I've tried a few different approaches to the problem.
- Multiple cells and `dataCellForTableColumn:` while this allows rendering to happen properly for all cell types, I lose bindings.- NSProxy: I've also tried using a proxy object that I thought would forward all methods to the selected cell type behind it, but again, bindings don't seem to work here.
Has anybody had any experience with this kind of problem before? Or is this one of the cases where bindings isn't going to cut it, and I'll need to do the heavy lifting myself?

This is all mockup / test code, so please excuse the sloppyness.
So I have a table that I'm using in conjunction with the jQuery datatable plugin:
[http://www.datatables.net/](http://www.datatables.net/)
My table markup is as follows:
```

</tbody>
</table>
```
Now, the functionality I'm going for is:
On hover change the row background color
If hovering for more than 'x' seconds slide down a sub-row for the row being hovered over.
Here is a screenshot of the effect working correctly (generally):
Upon leaving the row with one's mouse the sub-row slides back up.
This all works, but it seems that each time it slides back up it falls short by about a pixel. Here is an image after hovering/un-hovering 10 times. This is the table in the state after the sub-row slides up (meaning it's not just the sub-row showing with no text).
If I change slideUp/slideDown to fadeIn/fadeOut everything works fine and I don't get extra pixels. (I'll probably end up just using the fades, but i'm curious about this behavior).
This is what safari is reporting about the DOM in the bugged state (also, why can't I copy/paste in the Safari Web Inspector?):
And finally, here is some sloppy jQuery that handles the actual moving parts:
```
<script language="javascript" type="text/javascript">
$(document).ready(function() {
$('#dexterIndex').dataTable()
$('#dexterIndex tbody tr')
.hover(function() {
var table_row = this
table_row.hovering = true
window.setTimeout(function() {
if (table_row.hovering) {
$('.school-info').slideUp('fast', function() {
$(this).remove()
})
table_row.hovering = false
var tr = $('<tr />').attr({'class': 'school-info',})
$(table_row).after(tr)
$('<td />')
.attr({
'colspan': 5
})
.css({
'display': 'none'
})
.text("Sub Row")
.appendTo(tr)
.slideDown('fast')
}
}, 2000)
$(this).children().each(function() {
(this.oldColor === undefined)? this.oldColor = $(this).css('background-color'): null;
$(this).css({'background-color': '#f3ffc0'})
})
},
function() {
this.hovering = false
$('.school-info').slideUp('fast', function() {
$(this).remove()
})
$(this).children().each(function() {
$(this).css({'background-color': this.oldColor})
})
})
})
```
TL;DR: slideUp slides up one pixel less each time, fadeOut doesn't have any issues.
If anyone can shed some light on this issue it'd be greatly appreciated.

Everything was working until I start to use memcache. PyDev reports the errors and I don't know how to fix it:

Sure, it is only PyDev checker problem. Code is correct and run on GAE.

1. I'm using PyDev 1.5.0 but experienced the same with 1.4.8.
2. My PYTHONPATH includes (set in Project Properties/PyDev - PYTHONPATH): C:\Program Files\Google\google_appengine C:\Program Files\Google\google_appengine\lib\django C:\Program Files\Google\google_appengine\lib\webob C:\Program Files\Google\google_appengine\lib\yaml\lib

I took a look at `C:\Program Files\Google\google_appengine\google\appengine\api\memcache\__init__.py` and found `get()` is not declared as `memcache` module function. They use the following trick to do that (I didn't hear about such possibility):
```

So far in my endeavor to create a line between a point and its projected

before including any nearest neighbor analysis, I got the results shown in
this image:
As you can see, each point in pink is connecting to all the projected points, whereas, I only want to connect each pink x to its respective projection.
On IRC, It was recommended that I use [BostonGIS's nearest neighbor method](http://www.bostongis.com/PrinterFriendly.aspx?content_name=postgis_nearest_neighbor_generic). I inputed the function to PostgreSQL and tried it unsuccessfully as outlined below. I am assuming that my error is due the wrong parameter type.

3. Shift it over with CSS position: relative; top: 5px; left: -5px;

What I need to do is something like this:
[](https://i.stack.imgur.com/U0OEd.png)
[drobilla.net](http://drobilla.net/blog/wp-content/uploads/2008/09/ingen.png)
[](https://i.stack.imgur.com/vti02.jpg)
[mcgill.ca](https://www.cim.mcgill.ca/~clark/nordmodularbook/images/hallseymrk1.jpg)
So, basically, it's an area where I can draw some rectangles (boxes) that represent synth modules with input and output ports that I can connect with wires.
The problem is that I can't figure out how two create a widget for the editing area: Using a simple 2D drawing context where I draw the boxes manually seems to be the only logical way to do this, but doing this I loose all the great event management that qt gives me.
I'm wondering if there's the possibility of creating a custom layout that simply takes coordinates of created "boxes" and put them on the screen, so that I implement the boxes as subclasses of QWidget (and reusing qt's event handling system) and I add them to the window as I do usually.
Or maybe there's a better way?

I am using the PaperConfiguration as the root aggregate.
I want to select all PaperConfiguration objects for a given Tier and AcademicYearConfiguration. This works really well as per the following example:
```
ICriteria criteria =
session.CreateCriteria<PaperConfiguration>()
.Add(Restrictions.Eq("AcademicYearConfiguration", configuration))
.CreateCriteria("Paper")
.CreateCriteria("Unit")
.CreateCriteria("Tier")
.Add(Restrictions.Eq("Id", tier.Id))

```
(Perhaps there is a better way of doing this though).
Yet also need to know how many ReferenceMaterials there are for each PaperConfiguration and I would like to get it in the same call. Avoid HQL - I already have an HQL solution for it.
I know this is what projections are for and [this question](https://stackoverflow.com/questions/532483/nhibernate-and-collection-counts) suggests an idea but I can't get it to work.
I have a PaperConfigurationView that has, instead of `IList<ReferenceMaterial> ReferenceMaterials` the ReferenceMaterialCount and was thinking along the lines of
```
ICriteria criteria =
session.CreateCriteria<PaperConfiguration>()
.Add(Restrictions.Eq("AcademicYearConfiguration", configuration))
.CreateCriteria("Paper")
.CreateCriteria("Unit")
.CreateCriteria("Tier")
.Add(Restrictions.Eq("Id", tier.Id))
.SetProjection(
Projections.ProjectionList()
.Add(Projections.Property("IsSelected"), "IsSelected")
.Add(Projections.Property("Paper"), "Paper")
// and so on for all relevant properties
.Add(Projections.Count("ReferenceMaterials"), "ReferenceMaterialCount")
.SetResultTransformer(Transformers.AliasToBean<PaperConfigurationView>());
return criteria.List< PaperConfigurationView >();
```
unfortunately this does not work. What am I doing wrong?
The following simplified query:
```
ICriteria criteria =
session.CreateCriteria<PaperConfiguration>()
.CreateCriteria("ReferenceMaterials")
.SetProjection(
Projections.ProjectionList()
.Add(Projections.Property("Id"), "Id")
.Add(Projections.Count("ReferenceMaterials"), "ReferenceMaterialCount")
).SetResultTransformer(Transformers.AliasToBean<PaperConfigurationView>());
return criteria.List< PaperConfigurationView >();
```
creates this rather unexpected SQL:
```
SELECT
this_.Id as y0_,
count(this_.Id) as y1_
FROM Domain.PaperConfiguration this_
inner join Domain.ReferenceMaterial referencem1_
on this_.Id=referencem1_.PaperConfigurationId
```
The above query fails with ADO.NET error as it obviously is not a correct SQL since it is missing a group by or the count being count(referencem1_.Id) rather than (this_.Id).

1,500,700 | 1 | 1,501,874 | null | 2 | 673 | I may be doing this all wrong, but I thought I was on the right track until I hit this little snag. Basically I was putting together a toy using NSCollectionView and trying to understand how to hook that all up using IB. I have a button which will add a couple of strings to the NSArrayController:
The first time I press this button, my strings appear in the collection view as expected:
The second time I press the button, the views scroll down and room is made - but the items don't appear to get added. I just see blank space:
The button is implemented as follows (controller is a pointer to the NSArrayController I added in IB):
```
- (IBAction)addStuff:(id)control
{
[controller addObjects:[NSArray arrayWithObjects:@"String 1",@"String 2",@"String 3",nil]];
}
```
I'm not sure what I'm doing wrong. Rather than try to explain all the connections/binds/etc, if you need more info, I'd be grateful if you could just take a quick look at the [toy project](http://dl.getdropbox.com/u/545670/Toy.zip) itself.
After more experimentation as suggested by James Williams, it seems the problem stems from having multiple objects with the same memory address in the array. This confuses either NSArrayController or NSCollectionView (not sure which). Changing my addStuff: to this resulted in the behavior I originally expected:
```
[controller addObjects:[NSArray arrayWithObjects:[NSMutableString stringWithString:@"String 1"],[NSMutableString stringWithString:@"String 2"],[NSMutableString stringWithString:@"String 3"],nil]];
```
So the question now, I guess, is if this is a bug I should report to Apple or if this is intended/documented behavior and I just missed it?

Typically I would include the whole connection string (user and password) inside the web.config, but I was feeling frisky this morning so I decided to exclude the password from the connection string. Unfortunately for me, I cannot seem to figure out how to pass or set the password before I manipulate the database, and all the searching I've done so far have not yielded any fruitful results. All I have currently are a couple of lines that add a new record:
```
_entities.AddToUploadSet(uploadFile);
_entities.SaveChanges();
```
I see there is a `ConnectionString` property inside of `_entities.Connection`, but I failed to find anything useful like a password property.
Can anyone help me out? Thanks!

For clarification, this screenshot shows the step where I can choose whether or not to include the password in the web.config file:
So as you can see, I need to set it in my application code as the prompt suggests.

1,504,241 | 1 | 1,504,340 | null | 0 | 774 | I'm trying to build a Silverlight App that accesses and presents data from a MySQL database. I'm trying to use Entity Framework to model the MySQL data and RIA Services to make the data via EF available to Silverlight.
My Silverlight App is showing the correct columns in the datagrid, but it does not show the data ([alternate link to image](http://screencast.com/t/yc6lXUjU0)) :
When I look at the DomainService file (used for RIA Services), I see this:
```
public IQueryable<saw_order> GetSaw_order(int intOrder)
{
return this.Context.saw_order
.Where(o => o.Wo == intOrder);
}
```
To test this step, I modified the LINQ to remove the where so that all I had was `return this.Context.saw_order;`. When I did this, I was able to check the MySQL server and verify that the query was in fact sent to the MySQL server and the MySQL server was "Writing to NET" and trying to send data back. The query sent from my test machine was valid.
From my test above, it seems that data is correctly being sent to the MySQL server but is lost somewhere on its return. My difficulty now is trying to figure out where in the chain (Entity Framework to RIA Services to Silverlight client) the data is getting lost and I'm not sure how to debug this at different points.
For example, what are other ways I might test Entity Framework to make sure EF is not the problem? How might I test RIA services? Should I test on the Silverlight Client?
I'm struggling with learning C# and am not sure what to do to test. How might I "catch" the return in the DomainService so I can do some basic debugging.
Any help is very much appreciated.

I have a three columns (A,B,C) containing numeric digits and then two columns (key 1, key2) that is also numeric. Next to the two columns are sensor attribute data that is yellowed under (AB,BC,AC). My code below is supposed to look at athe attribute cells and see under which columns (AB,BC,AC) are yellow. Then it takes the key pairs (key 1, key2) and finds a match in the three column matrix in terms of values and the relative order of the value in the three columns. I've been doing this manually and its so much of a pain I need to try to code it but I don't know if its possible. The problem I have is that the yellowed cells tells the relative order of the key pairs to find the match in the three columns and I do not know how to pull that off.
Sample file here: [http://www.filefactory.com/file/a0egf75/n/Relative_Position_Macro_xls](http://www.filefactory.com/file/a0egf75/n/Relative_Position_Macro_xls)
If anyone can offer me some suggestions, I would really appreciate it.

1,513,383 | 1 | 1,518,907 | null | 4 | 2,897 | I have a number of spherical longitude/latitude coordinates for points on a sphere that I need to visualize. For that purpose, I transformed the points to cartesian coordinates and built a mesh of triangles that I can render with VTK. Works so far.
Now I want to use a texture for the sphere model. Therefore I transformed the spherical coordinates to texture coordinates and assigned these to each point. This works for the majority of the sphere's surface triangles and the result looks acceptable.
But, for the triangles on the opposite side of the prime meridian, where the texture wraps, the triangles are textured incorrectly: Instead of repeating the texture and mapping “over the texture boundary”, the whole texture gets squeezed onto the single triangle.
Here is a picture of how it looks like:
The zick-zack line is obviously wrong, the blue line should be visible instead. The whole texture is mapped on the triangles, resulting in red and white stripes. This makes sense since, for the triangles in question, the texture coordinates span the whole texture space.
To illustrate this problem, which is not specific to spheres but all closed objects, I have created the following figure:
In the upper rectangle, we see a triangle that spans over the texture boundaries with computed texture coordinates A, B and C. Since the texture can be tiled, this is how I would like the triangle to be rendered.
The lower triangle shows how the texture coordinates are interpreted currently. The coordinates of the edges A, B and C are the same, but this time, the majority of the texture is used for the triangle, instead of tiling the texture at the borders.
I am sure there is quite a common mistake I made but I didn't find anything to help me yet. Have any hints for me?

1,513,811 | 1 | 1,513,979 | null | 27 | 54,803 | I started playing around with OpenGL and GLUT. I would like to draw some points, but the problem is that they turn out to be squares, and I would like them to be round dots (filled circles).
This is what I do:
```
void onInitialization( )
{
glEnable( GL_POINT_SMOOTH );
glEnable( GL_BLEND );
glBlendFunc( GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA );
glPointSize( 6.0 );
}
void onDisplay()
{
glClearColor( 1.0f, 1.0f, 1.0f, 1.0f );
glClear( GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT );
glBegin( GL_POINTS );
glColor3f( 0.95f, 0.207, 0.031f );
for ( int i = 0; i < g_numPoints; ++i )
{
glVertex2f( g_points[i].X, g_points[i].Y );
}
glEnd();
glFinish();
glutSwapBuffers();
}
```
This is the result:
The points show up where expected, only their shape is wrong.

Their explanation on this misleading error message is as following
> Note:
It is recognized that the
message for Msg 313 is misleading and
does not convey the actual cause of
the failure. This awkward usage stems
from the inability to raise an
explicit error from within a TVF.
Nevertheless, the value of returning a
recognizable, if inaccurate, error was
deemed preferable to simply returning
an empty result. An empty result set
would not be distinguishable from a
valid query returning no changes.
Here is a demonstration of what the note meant [RAISERROR](http://msdn.microsoft.com/en-us/library/ms178592.aspx)
There are times when I'd like to throw an error and you cannot use [TRY..CATCH](http://msdn.microsoft.com/en-us/library/ms175976.aspx) within UDF since it also has a side-effect like `RAISERROR`.
Now the is, how do get around this problem?
I am sure that you have faced with this restriction before.
What alternative would you suggest?

Let's suppose that you are forced to use `UDF`.

1,516,141 | 1 | 1,516,315 | null | 0 | 305 | What is the syntax to use the [TestDescriptionAttribute][1] of a test to populate the Description column in the Test Results window?
Context: Visual Studio 2008 Team System
I've read the documentation, but am not able to find a concrete example.
Based, loosely, on Ngu's suggestion, I've tried:
```
using GlobalSim;
using Microsoft.VisualStudio.TestTools.UnitTesting;
using Microsoft.VisualStudio.TestTools.WebTesting;
namespace GlobalSimTests {
/// <summary>
///This is a test class for PongerTest and is intended
///to contain all PongerTest Unit Tests
///</summary>
[TestClass()]
[TestDescriptionAttribute( "hello" )]
public class PongerTest {
private TestContext testContextInstance;
/// <summary>
///Gets or sets the test context which provides
///information about and functionality for the current test run.
///</summary>
public TestContext TestContext {
get {
return testContextInstance;
}
set {
testContextInstance = value;
}
}
/// <summary>
///A test for Ping
///</summary>
[TestMethod()]
public void PingTest () {
Ponger target = new Ponger();
string expected = "Pong";
string actual;
actual = target.Ping();
Assert.AreEqual( expected, actual );
}
}
}
```
This compiles, but doesn't display the test description in the Description column of the Test Results window.
I've also tried this syntax:
```
/// <summary>
///A test for Ping
///</summary>
[TestMethod()]
[TestDescription( "hello" )]
public void PingTest () {
Ponger target = new Ponger();
string expected = "Pong";
string actual;
actual = target.Ping();
Assert.AreEqual( expected, actual );
}
```
Which returns from the compiler:
Attribute 'TestDescription' is not valid on this declaration type. It is only valid on 'class' declarations.
Here is the syntax that works. Thanks all!
```
/// <summary>
///A test for Ping
///</summary>
[TestMethod()]
[Description( "Hello" )]
public void PingTest () {
Ponger target = new Ponger();

I can use an algorithm that I created to find the locations of all 3 points of any triangle that the player is in contact with, but I don't know how to use those points to work out the rotation of the triangle.
By the rotation, I mean the direction of the normal away from the centre of the face, i.e., the angle at which a person would be leaning if they stood on that surface. Can someone come up with a series of equations that will allow for this problem to be solved?
