3,791,024 | 1 | 3,791,187 | null | 8 | 20,615 | jQuery.validate doesn't seem to change the background color of the invalid element by default. Is it also possible to change the background color of a `select` element? Most of my elements are `input type="text"`, but I need an indicator for the select form elements. I am using the default generated messages, as they don't fit my layout.
The following code change the background color of the `input` elements, but it never reverts to its previous style:
(sample)
```
<div class="field">
<div class="labelName_fb">
<label for="email">Email</label>
</div>
<div class="divforText3">
<div class="divLeft"></div>
<div class="textbox-image3">
<input class="txt required" id="emailCreate" name="emailCreate" value="" maxlength="100" type="text" style='width:180px'>
</div>
<div class="divright"></div>
</div>
</div>
```
Where the `input` element is given the `jqInvalid` error class on error.
```
/* line 3 */ .error { background: #ffdddd; } /* I have since removed the errorClass option */
/* line 254 */ .field .txt {background:transparent none repeat scroll 0 0;border:medium none;color:#000;font-size:11px;width:130px; margin:5px 0;}
```

3,791,173 | 1 | 3,791,777 | null | 1 | 347 | I am new to OpenGL. I am using JOGL.
I downloaded this [model](http://www.turbosquid.com/3d-models/3d-mitsubishi-l200/394290). It has a bunch of textures. I'm trying to apply "truck_color-blue.jpg" here, but I'm not sure I'm doing it right. This is what I'm seeing:
Essentially, what I am doing is recording all the `vt`, `v`, and `vn` entries, then using the `f` lines to index into them. This is the code that makes the `glTexCoord*()` call:
```
if (facePoint.textureIndex != null) {
Vector2f texCoords = getTexture(facePoint.textureIndex);
gl.glTexCoord2f(texCoords.x, texCoords.y);
}
// ...
Point3f vertex = getVertex(facePoint.vertexIndex);
gl.glVertex3f(vertex.x, vertex.y, vertex.z);
```
I suspect that I'm not correctly matching up the texture coords to the vertices. The model says that it is UV mapped. Does that mean I need to do textures differently?
My code to read .obj files:
```

3,791,372 | 1 | 3,791,547 | null | 5 | 18,481 | I've encountered a strange error when attempting to update a SharePoint 2010 list that I have linked to via Microsoft Access 2010.
Error: Data cannot be inserted because there is no matching record.
This occurs in 2 scenarios:
1. I attempt to run any UPDATE query against the list in MS Access
2. I attempt to update a record from the list if the list view is filtered
The second item might need an explanation. If I simply open the linked list in Access, scroll down to a record I want to edit, and edit it, it works. If I filter that view first (for example, showing only records with a checkbox field checked), I cannot edit any records and get the error.
This only happens in one particular environment; others work fine with either approach. I've checked permissions (I have full control of the list, I am a Site Collection Administrator, etc.). I have tried linking to the list in various ways: from within Access, from the "Open with Access" ribbon button in SharePoint. I've deleted and recreated the Access DB file... no luck.
Also, Google has no knowledge of this particular error: searches for the exact error text come up with 0 results.
Any idea what to check? Running SQL-style queries against this SharePoint list is the only viable option for maintaining it.

"a2 b2 c2"
"a3 b3 c3"
"a4 b4 c4"
"a5 b5 c5"
"a6 b6 c6"
......
I've already wrote one version of the program, but it start by reading all the files, and that is very inneficient because those file can be 200Mb in size.
how to write a program to retrieve a line in each file and displays my matches before moving on to the following lines in the files. This certainly will avoid loading all the files and make good use of the garbage collector?
sorry i dont know how to insert images here, it always fails, but while profiling, memory usage looks like stairs from the top to the bottom
ok it's works 1
thanks for reply
Thanks to FUZxxi his answer really help me, but there was a problem when files did not have the same number of line, to solve this problem, I've re-write his program this way
```
printLines :: [[String]] -> IO ()
printLines [] = return ()
printLines ss = do
ss' <- printFirstLine ss
if and $ map null ss' then putStrLn "finish" else printLines ss'
printFiles :: [FilePath] -> IO ()
printFiles paths = do
files <- mapM readFile paths
let fileLines = map lines files
printLines fileLines
sliceFirstRow :: [[String]] -> ([String],[[String]])
sliceFirstRow list = unzip $ map getFirst list
printFirstLine :: [[String]] -> IO ([[String]])
printFirstLine ss = do
let (fline,lline) = sliceFirstRow ss
mapM_ putStrLn fline
return lline
getFirst :: [String] -> (String, [String])
getFirst [] = ("",[])
getFirst (x:xs) = (x,xs)

3,791,591 | 1 | 3,792,853 | null | 2 | 1,246 | I'm just testing this stuff out, so I don't need an alternate approach (no GL extensions). Just hoping someone sees an obvious mistake in my usage of GLES.
I want to take an bitmap of a glyph that is smaller than 32x32 (width and height are not necessarily powers of 2) and put it into a texture so I can render it. I've first created an empty 32x32 texture then I copy the pixels into the larger texture.
```
Gluint texture;
glGenTextures(1, &texture);
glBindTexture(GL_TEXTURE_2D, texture);
glPixelStorei(GL_UNPACK_ALIGNMENT, 1);
glTextImage2D(GL_TEXTURE_2D, 0, GL_ALPHA, 32, 32, 0,
GL_ALPHA, GL_UNSIGNED_BYTE NULL);
glTexSubImage2D(GL_TEXTURE_2D, 0, 0, 0, bitmap.width(), bitmap.height(),
GL_ALPHA, GL_UNSIGNED_BYTE, bitmap.pixels());
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_NEAREST);
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_NEAREST);
glTexParamteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_CLAMP_TO_EDGE);
glTexParamteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_CLAMP_TO_EDGE);
```
Then I try to draw only the bitmap portion of the texture using the texture coordinates:
```
const GLfloat vertices[] = {
x + bitmap.width(), y + bitmap.height(),
x, y + bitmap.height(),
x, y,
x + bitmap.width(), y
};
const GLfloat texCoords[] = {
0, bitmap.height() / 32,
bitmap.width() / 32, bitmap.height() / 32,
0, 0,
bitmap.width() / 32, 0
};
const GLushort indices[] = { 0, 1, 2, 0, 2, 3 };
glEnableClientState(GL_VERTEX_ARRAY);
glEnableClientState(GL_TEXTURE_COORD_ARRAY);
glVertexPointer(2, GL_FLOAT, 0, vertices);
glTexCoordPointer(2, GL_FLOAT, 0, texCoords);
glDrawElements(GL_TRIANGLES, 6, GL_UNSIGNED_SHORT, indices);
```
Now if all were well in the world, the size of the square created by the vertices would be the same size as the bitmap portion of the texture and it would draw my bitmap exactly.
Lets say for example that my glyph was 16x16, then it should take up the bottom left quadrant of the 32x32 texture. Then the texCoords would seem to be correct with (0, 0.5), (0.5, 0.5), (0, 0) and (0.5, 0).
However my 12x12 'T' glyph looks like this: 
Anyone know why?
BTW. I start by setting up the projection matrix for 2D work as such:
```
glMatrixMode(GL_PROJECTION);
glLoadIdentity();
glOrtho(0.0f, 480, 800, 0.0f, 0.0f, 1.0f);
glDisable(GL_DEPTH_TEST);
glMatrixMode(GL_MODELVIEW);
glLoadIdentity();
glTranslate(0.375f, 0.375f, 0.0f); // for exact pixelization
glEnable(GL_BLEND);
glBlendFunc(GL_SRC_ALPHA, GL_ONE_MINUS_ALPHA);
glEnable(GL_TEXTURE_2D);
glClearColor(1.0f, 1.0f, 1.0f, 1.0f);
glClear(GL_COLOR_BUFFER_BIT);

I was going good with MVC review when I came across the latest Dynamic Data (which in past was called Dynamic Data Templates).
Correct me if I'm wrong but I believe in backend both MVC2 & DD use the MVC pattern but then DD supports server-side controls and has a lot of automation using its latest scaffolding technique. We can make a running website with-in a few hours and DD handles most of it for us.
MS people day it is 'massively' flexible and configurable. However, as I went on looking for online resources I was disappointed (compared to the solutions available in MVC) a recent post from the asp.net forum hit me hard -

any more - please read this Microsoft
And it looks like a non-MS guy has done more in DD then the actual team!

```
x>=0
y>=0
f(x,y)=x^2+y^2>=100
g(x,y)=x^2+y^2<=200
```
`x``y`
Graphically it can be represented as follows, the blue region is the region that satisfies the above inequalities:
The question now is, is there any function in Matlab that finds every admissible pair of `{x,y}`? If there is an algorithm to do this kind of thing I would be glad to hear about it as well.
Of course, one approach we can always use is brute force approach where we test every possible combination of `{x,y}` to see whether the inequalities are satisfied. But this is the last resort, because it's time consuming. I'm looking for a clever algorithm that does this, or in the best case, an existing library that I can use straight-away.
The `x^2+y^2>=100` `and x^2+y^2<=200` are just examples; in reality `f` and `g` can be any polynomial functions of any degree.

3,794,406 | 1 | 3,796,352 | null | 1 | 4,302 | i'm pretty confused over the following issue and would be grateful for some clarity.
generally, how i work involves designing all of my graphics in Flash Authoring, converting them to Sprite symbols by changing the base class to flash.display.Sprite, give my instances names and finally export them to ActionScript.
the approach actually permits me to dynamically create properties in code on my Sprite instances that i've exported to ActionScript, just as if they were instances of MovieClips. i'm not entirely sure why i'm able to do this, but i can. in polling the objects to make sure of their superclass, they are indeed Sprites and not MovieClips.
however, as expected, if i program a new sprite from scratch in code and try to dynamically add a property to the new programmed sprite a compile time error will result.
```
package
{
import flash.display.Sprite;
import flash.utils.getQualifiedSuperclassName;
public class Document extends Sprite
{
public function Document()
{
trace(getQualifiedSuperclassName(blueOvalInstance));
//flash.display::Sprite (it's not a MovieClip)
trace(blueOvalInstance.hasOwnProperty("currentFrame"));
//false (ok, ok, it's definately not a MovieClip)
blueOvalInstance.myNewProperty = true;
//dynamically added boolean property on a Sprite instance
trace(blueOvalInstance.hasOwnProperty("myNewProperty"));
//true. fancy that! my Flash Authoring exported Sprite has a dynamically added property
codeSprite();
}
private function codeSprite():void
{
var myCodedSprite:Sprite = new Sprite();
myCodedSprite.graphics.beginFill(0xFF0000);
myCodedSprite.graphics.drawRect(0, 0, 100, 100);
myCodedSprite.graphics.endFill();
addChild(myCodedSprite);
myCodedSprite.anotherNewProperty = true;
//dynamically added boolean property on a Sprite instance, just like before!
//Compile Time Error!!!
//1119: Access of possibly undefined property anotherNewProperty through a reference with static type flash.display:Sprite.
}
}
}
```
so why is it that can i dynamically add properties to exported sprites in my document class if they are not MovieClips, while i can not if i create them myself in code?
the following image shows a new BlueOval symbol being exported to ActionScript from Flash Authoring with the base class of Sprite (not MovieClip). notice the new green (instead of blue) colored "Movie Clip" icon in the library panel.

However, when I try to locate the folder referenced above, it does not exist:
As you can see, there is no `sf/` directory under `web/`. What am I doing wrong?

3,797,277 | 1 | 3,797,292 | null | 0 | 2,604 | I wanted to have two buttons on the both end of Navigation Bar (in iPad's Detail View Controller).
So I created two UIToolbars and I set the them as Left&RightBarButtonItems.

the code I used ,

[lItems release];
leftToolbar.barStyle =UIBarStyleBlackTranslucent;
leftToolbar.tintColor=[UIColor clearColor];

usleep(3000000); usleep(3000000);
usleep(3000000); usleep(3000000);

}
```
The memory usage graph went like this (the bottom pink colored graph tracks memory).
Though this program did not run out of memory, any more memory requirements would lead to the `malloc` failing and then a segmentation fault due to the `ar[i][123] = 456;` line.
I want to put a limit on the memory allocation through my program, but also do not want to bind my program statically.
> For example,
So, if my program is run on a machine with 8GB of memory, it can use a max of 4GB, but in case the program runs on a machine with 256MB, only 128MB should be available to the program.
Also, I want to do this from within my program, rather than controlling the amount of memory available using some external utility.

The first time it works fine, but in future runs there are horizontal bars on the top and bottom of the map view during the animation. It looks something like this:
I've tried playing with the cache setting, removing other views, etc. It doesn't happen in the simulator but it happens on OS 4.1.x and 3.1.x.
If I don't hide the `tableView`, I see bits of the table instead of the grey bars, so I think the mapview is being resized incorrectly during the flip.

3,800,026 | 1 | null | null | 3 | 8,408 | I would like to create a CSS/HTML version of this notepad on my page:
I was thinking of using a simple table like this:
```
<div id="notepad">
<table>
<thead id="tbl_header">Comments</thead>
<tr></tr>
<tr>
<td class="col1">Dot</td>
<td class="col2">Text for column 2</td>
</tr>
<tr>
<td class="col1"></td>
<td class="col2"></td>
</tr>
<tr>
<td class="col1"></td>
<td class="col2"></td>
</tr>
<tr>
<td class="col1"></td>
<td class="col2"></td>
</tr>
<tr>
<td class="col1"></td>
<td class="col2"></td>
<td class="col3"></td>
</tr>
</table>
</div>
```
So what I was thinking was cutting up the graphic. Have the top part, be the bg img for the `<thead>`.
Then just create one of the lines as the rows (there would be two graphics, one for col1 and col2 - so when a new row is created the bg of both columns would be populated), so that it can scale vertically as needed. Then, for the last set, I have two more graphics. One is for col1. One for col2 (which is the regular row but a little narrower in width) and the curl would be col3.
Is there a scalable way I can do this, using CSS & HTML only (no JS or jQuery) ?
Thanks.
P.S. Or is there another way to create this same thing without having to use bg images - and just using CSS?

}
TextView message = (TextView) layout.findViewById(R.id.alert_text);

((Button) layout.findViewById(R.id.okay_button)).setOnClickListener(new View.OnClickListener() {

3,802,614 | 1 | 3,802,673 | null | 8 | 42,388 | I am a iPhone developer stuck with some basic CSS properties ;)
I want to show something like this:
This is what I have:
```
<div class="cell">
<div class="cell_3x3_top">
<div class="cell_3x3_type rounded_left">type</div> <!--UPDATED:2010/09/29-->
<div class="cell_3x3_title rounded_right">title</div><!--UPDATED:2010/09/29-->
</div>
<div class="cell_3x3_content rounded_left rounded_right">content</div><!--UPDATED:2010/09/29-->
</div>
```
and the css:
```
div.cell_3x3_top{
height:20%;
margin: 0 0 0 0;
padding: 0 0 0 0;
border: none;
margin-bottom: 1px; /*to compensate space between top and content*/
text-align: center;
vertical-align: middle;
}
div.cell_3x3_type{
width:20%;
float:left;
background-color: inherit;
margin-right: -2px; /*UPDATED:2010/09/29*/
}
div.cell_3x3_title{
width:80%;
float:left;
background-color: inherit;
margin: 0 0 0 0; /* maybe not neccesary*/
padding: 0 0 0 0; /*maybe not neccesary*/
margin-left: -1px; /*UPDATED:2010/09/29 */
}
div.cell_3x3_content{
height:80%;
background-color: inherit;
}
```
But when I render my content with above code `title` div seems to be too large and it appears underneath `type` div, Why is this?
`type` div is 20% width, `title` is 80% width so it should be 100% exactly. Is any margin or other metric I am forgetting here?
I have tried to move `title` div to the left using margin but is still buggy. I wonder what is the correct way of getting something like the picture?
(Not exactly because if you look closer `title` div is a little bit shorter than it should be. See that its right border is not aligned with `content` div.)
Thanks in advance.
EDIT: 2010/09/28
This is actually what I want to achieve:
and this is what I have:
Above code (updated a little bit) would work if I wouldn't have bordered divs. Since border width is 1px what I need is to set `type` div width to 20%-2px (left border + right border = 2px) and `title` div to 80%-2px
```
.rounded_left{
border-top-left-radius: 4px 4px;
border-bottom-left-radius: 4px 4px;
border-color:gray;
border-width: 1px;
border-style:solid;
}
```
(.rounded_right is similar)
This is not related to `clear:both` property I believe. I tried and didn't had any effect since my `content` div was good form the beginning.
In short: How can I make a div including its border to be let's say exactly 20% width?
Ignacio
ANSWER:
I realized that a wrapper div around type and title respectively solves the problem. So my answer is kind of like this:
```
<td class="cell">
<div class="cell_3x3_top bordered">
<div class="cell_3x3_type_container"><div class="cell_3x3_type rounded_left full_height">6</div></div>
<div class="cell_3x3_title_container"><div class="cell_3x3_title rounded_right full_height">title</div></div> </div>
<div class="cell_3x3_content rounded_left rounded_right">content</div>
</td>
```
I set 20% and 80% in the containers and the borders in the inner div.

3,803,673 | 1 | 3,811,090 | null | 1 | 845 | I have a function which updates the centroid (mean) in a K-means algoritm.
I ran a profiler and noticed that this function uses a lot of computing time.
It looks like:
```
def updateCentroid(self, label):
X=[]; Y=[]
for point in self.clusters[label].points:
X.append(point.x)
Y.append(point.y)
self.clusters[label].centroid.x = numpy.mean(X)
self.clusters[label].centroid.y = numpy.mean(Y)
```
So I ponder, is there a more efficient way to calculate the mean of these points?
If not, is there a more elegant way to formulate it? ;)
EDIT:
Thanks for all great responses!
I was thinking that perhaps I can calculate the mean cumulativly, using something like:
where x_bar(t) is the new mean and x_bar(t-1) is the old mean.
Which would result in a function similar to this:
```
def updateCentroid(self, label):
cluster = self.clusters[label]
n = len(cluster.points)
cluster.centroid.x *= (n-1) / n
cluster.centroid.x += cluster.points[n-1].x / n
cluster.centroid.y *= (n-1) / n
cluster.centroid.y += cluster.points[n-1].y / n
```

I used a dummy value to verify both the string parameter in the SelectSingleNode function and the newValue string parameter being passed to my function and they both contain values, so I don't understand why it's throwing a null reference exception.

Yes, the SlectSingleNode function is not returning a value. I just started working with XPath, this seemed to have worked when I was using last week. I'm not sure why it has stopped working now.

Because it is moving the mass will give data which will vibrate in some amplitude depending on the mass of the object. Bigger the mass - bigger the vibrations.
Are there any methods for filtering such kind of noise from that data?
May be using some formulas of vibrations? Have no idea what kind of formulas or algorithms (filters) can be used here. Please suggest anything.
EDIT 2:
Better picture, I just draw it for better understanding:
Not very good picture. From that graph you can see that the frequency is the same every
time, but the amplitude chanbges periodically. Something like that I have when there are no objects on the moving road. (conveyer belt). vibrating near zero value.
When the object moves, I there are the same waves with changing amplitude.
The graph can tell that there may be some force applying to the system and which produces forced occilations. So I am interested in removing such kind of noise. I do not know what force causes such occilations. Soon I hope I will get some data on the non moving road with and without object on it for comparison with moving road case.

Is it just useless to benchmark algorithms in this manner in scripting languages?
: For NullUserException:
```
function factrec($x) {
if($x <= 1) {
return $x;
} else {
return $x * factrec($x - 1);
}
}
```

3,808,663 | 1 | 3,811,135 | null | 1 | 550 | I have a recursively defined user control that needs the following properties:
there are two columns
the first contains a single border around some text
the second column contains a stack of these same type of controls (the recursive part)
if the box in the first column is shorter than the total height of the stacked boxes in the second column, the box should expand to make both columns the same height.
If the total height of the second column is shorter than the box in the first column, then the last item in the second column's stack should expand so they are the same height.
so for example, it might look like this:
Ok, so far what I have done is create a horizontal stack panel where the first item is a dock-panel containing a border and text... the second column is a vertical stack panel bound to a sublist, creating the recursive user control... like this..
```
<StackPanel Orientation="Horizontal" Background="AliceBlue">
<local:TMRequirementView Requirement="{Binding Baseline}" />
<StackPanel Orientation="Vertical">
<ItemsControl ItemsSource="{Binding Requirements}">
<ItemsControl.ItemTemplate>
<DataTemplate>
<local:TMGridView Baseline="{Binding}" />
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
</StackPanel>
```
Where the requirement looks like this:
```
<DockPanel>
<Border MinHeight="50"
BorderBrush="Black" BorderThickness="2">
<TextBlock Text="{Binding Description}"
TextWrapping="Wrap" Background="Transparent" Height="Auto" />
</Border>
</DockPanel>
```
Now this works great if the stacked column is taller, but it doesn't work if the first column is taller, and I get gaps. Any idea how to handle this mutual height dependency?
---
Update:
So by adding a border around the right columns stack panel, I was able to see that the stackpanel actually did receive the min-height changes. However, even though there was room to expand, the children of the stack panel didn't automatically update. If I fix the minheight of the stack panel before hand to something large, the children fill up. What I need to figure out is how to update the chidren's height based on changes to the stack panel's min-height.

3,808,769 | 1 | 3,809,136 | null | 3 | 800 | I have a list of items I'd like to show in a UITableViewCell. Right now, I'm simply using a cell.textLabel with commas separating each value, but I'd like to do something a little more dynamic.
How would I achieve something like this?
Would it be an array of UILabels with borders and radius on those borders?
Thanks for your ideas.

3,808,792 | 1 | 3,811,576 | null | 3 | 3,850 | I have two questions about axis labels:
1. How do I make a label at the Y2-axis, that shows a highlighted label following the dynamic price (y2-value) of the last bar/candlestick? As the red label in this example:
And possibly also the same on the `XAxis`, showing the time of the last bar.
1. Also I wonder how to make the time axis plot only every 30 min, and also that it should be full half hours, not arbitrary 30 min spots.. As also shown in the above image.
ZedGraph is awesome. But takes some time to figure out the tricks and tweaks.. :)

3,808,977 | 1 | null | null | 1 | 441 | I can't understand the problem here but this looks fine in all browsers cept Opera.
The HTML Code is as follows:
```
<table width="395" height="214" border="1">

<td colspan="2">Here is some content in here that has 2 colspans</td>
<td width="137">This only has 1 colspan.</td>
</tr>
<tr>
<td width="113">This has only 1 colspan also.</td>
<td colspan="2">This cell has 2 colspans now and should look presentable hopefully.</td>
</tr>
<tr>
<td colspan="3">This cell has 3 colspans within this table and should fill up the entire width of the table.</td>
</tr>
</table>
```
Now the Output looks like this in Opera:
But how do I make it look like this (as all other browsers look like):
The problem is actually much deeper than this, but this is the main basic overall problem.

The places where the float is not working are the location for "events near me", "Show" for the show month buttons ..
