Finally once uploaded image is loaded correctly they save. This has be using javascript and php. User can do all the rotating, zooming of their uploaded image and save file in php to send new file to user.

4,970,847 | 1 | 4,970,873 | null | 0 | 360 | I have a div (with a background image) and the image's width is 40px.
Now when I change the width to 20px it trims the image's right side. Is there any way to make it trim the left side instead?
Explanation : I have a square (4 images for corners and 1 image for upper and lower strip (the strip images are just 1x20 with repeat-x)). If I go to the welcome page which only contains the word "Welcome!", that the square's size will decrease. If I go to the 'My Character' page, the square's size will increase.
Meaning the square will always fit the content.
```
<table align="center">
<tr>
<td>
<div id="dynamic" class="DynamicWidth" >
<div class="ContentTL ContentCorners">
</div>
<asp:Panel ID="ContentTC" runat="server" CssClass="ContentTC ContentStrips">

<asp:Panel ID="ContentBC" CssClass="ContentBC ContentStrips" runat="server">
</asp:Panel>
<div class="ContentBR ContentCorners">
</div>
</div>
</td>
</tr>
</table>
```
Problem : Now, for the square's size to decrease and increase I can't use the 'px' unit since in the welcome screen, the whole square's width (2 corners and strip) might be 200px and in other pages, it's gonna be 1000px.
So I decided to use '%' - both corner with same % of width and the strip's width will complete to 100% (Ex: corners are 3% each, strip will be 96%)
It's all well but there's a problem - my corner image looks like this - bottom right() and bottom left(). if the page is really small - my left corner is ok but my right corner losses its roundness - almost looks like a square. (3% of 200px is really small and instead of trimming the left side of the picture it trims the right one which results in loss of the round size)
Solution : For this thing to work I asked you for a way to trim the image from the other side but than I thought of another solution : I took bottom left image () and simply flipped it (`-moz-transform: scaleX(-1);` I also have ones for opera,safari and IE) and the the width changes while triming it from the other side.
BTW : Now, I only need 2 images for corners instead of 4

Have a look at this page: [http://academic.research.microsoft.com/VisualExplorer#2037349](http://academic.research.microsoft.com/VisualExplorer#2037349).
The above page uses `SilverLight` and will recommend you to .
Like a curious human being I am now thinking of possible ways to implement it. A part of it seems easy:
1. Parse the documents
2. Make a list a authors(V) and distance between them (E) (i.e. co-author or co-co-author)
3. Traverse the above graph (Breadth First)
4. Show the top 5 or 6 connections
I know (or rather feel) this could be easily done in Flash, javascript or silverlight. But is there a way to do this using Java 2D/3D or OpenGL bindings?
Any or every thoughts are welcome.

4,971,254 | 1 | 4,971,522 | null | 1 | 11,213 | I have a main page, call it Main.php. On this page, is a button that when clicked, sets a div's innerHTML (already on Main.php, called divResults) with the results from Results.php.
When Results.php is called, the returned HTML "These Are The Results" is properly received and set as the contents to divResults on Main.php. However, any javascript from Results.php is not executed. As an example, I attempt to do a simple window.alert. Here is example code:
Main.php link button to begin the action:
```
<img src="$MyImageSource" onclick=\"ExpandDropdownDiv()\" />
```
Main.php javascript function ExpandDropdownDiv():
```
function ExpandDropdownDiv(){
if (window.XMLHttpRequest)/* code for IE7+, Firefox, Chrome, Opera, Safari */
{
xmlhttp=new XMLHttpRequest();
}
else
{/* code for IE6, IE5 */
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.onreadystatechange=function()
{
if (xmlhttp.readyState==4)/* && xmlhttp.status==200) */
{
document.getElementById("divResults").innerHTML=xmlhttp.responseText;
}
}
xmlhttp.open("GET","Results.php",true);
xmlhttp.send();
}
```
Results.php code example:
```
<script type="text/javascript">
alert("Success");
</script>
These Are The Results
```
The simple alert, from Results.php is just an example. If I were able to get this to work, I believe I could solve the rest of my problem on my own. However, I noticed a few comments suggesting to just place the alert in Main.php's javascript after i set the div's innerHTML. So, let me explain what I truly want to do with the javascript, after the div is set.
, shows some normal "Select" html elements, that have been transformed using jquery and the dropdown-check-list extension (.js). When the user clicks the colorful down arrow at the bottom, the div expands, and two more "Select" elements are generated within this other .php file... the html is returned, and placed in the div. Thus, i do not need to reload the entire page, and can place the new select dropdowns just beneath the existing ones.
The problem is, to "transform" these normal select elements, there is some javascript that needs to be executed against that HTML:
```
$(document).ready(function() {
$(".MultiSelect").dropdownchecklist( {firstItemChecksAll: true, maxDropHeight: 300 , searchTextbox: true, width: 100, textFormatFunction: function(options) {
var selectedOptions = options.filter(":selected");
var countOfSelected = selectedOptions.size();
var size = options.size();
switch(countOfSelected) {
case 0: return "All";
case 1: return selectedOptions.text();
/* case size: return "All"; */
default: return countOfSelected + " selected";
}
}
}
);
}
```
So, somehow I need to be able to execute javascript against the HTML that is generated from this other .php file. And simply calling the above code, after my divs innerHTML is filled, only re-generates the already existing dropdowns, not the two new ones.

4,971,452 | 1 | 4,983,379 | null | 1 | 1,566 | On selection I change the height of an UITableViewCell (loaded from a nib).
But the separator line is at a wrong position when I do this.
In the screenshot the first row is selected, and therefore bigger than the other ones.
From the separator positions it looks like the cell after the selected cell would be the big one. The second cell "has" exactly the size the first cell should have.
To change the height I save the selected indexpath in `tableView:didSelectRowAtIndexPath:` and compare it in `tableView:heightForRowAtIndexPath:`. If the indexpaths are the same I return the increased height. With the help of some NSLog I made sure that the correct height is returned.
And if I would resize the wrong cells the views of the cell would overlap, this doesn't happen.
If I click `Line 3` of the first cell the `tableView:didSelectRowAtIndexPath:` fires and the indexpath is the one for the first cell. So I guess the heights are correct, and the tableview draws the separators on the wrong position.

Does anybody has an idea what I did wrong?
Any solutions? Or should I file another bug with apple?

Edit: If I don't reuse my cells it works as expected.

Do you happen to know what is the T-SQL is for this sort of problem? Many thanks!
Tried the answer below, it worked perfectly. Here is the steps I used to test the answer:
1. Start up Microsoft SQL Management Studio.
2. Create the tables, with the data below.
3. Make sure that the ID in "Customer" is set to "Primary Key", and "identity".
4. Make sure that the ID in "Order" has no special settings (its a foreign key).
5. Open up a database diagram, then create a 1:* relationship between the "Customer" and "Order" tables.
6. Execute the script on the "Customer" table and the "Order" table, it will automatically normalize the data properly for you.
7. This is very useful if you are starting from a flat .csv file that has just been imported, and you want to copy the information into a normalized form in the database.

# Problem
I have the following mark-up:
```
<div id="progress-bar">
<div id="step-1" class="active"><p>1. Select Room</p></div>
<div id="step-2" class="incomplete"><p>2. Choose Date</p></div>
<div id="step-3" class="incomplete"><p>3. Confirm Order</p></div>
<div id="step-4" class="incomplete"><p>4. Make Payment</p></div>
</div>
```
The border it meant to surround all of the "steps", but instead cuts them in half, the only way I've found to solve is to explicitly set the height on this, although I thought the content inside would do this when not setting a height.
According to Chrome's Inspect Element, these are all of the CSS rules applied to it:
Progress Bar:
```
div#progress-bar {
padding-top: 10px;
padding-bottom: 10px;
border: 1px solid black;
}
```
Individual Steps only have mark-up for font styling (text-shadow, font-size), as well as (Where step-x corresponds to step-1,step-2 etc.):
```
div#step-x {
padding: 10px;
width: 227.5px;
float: left;
}
```
I did use a CSS reset, although I assumed the idea behind those was to remove all styling, so could that be an issue?

They do it by duplicating the TextBlock, and setting a Blur effect on it. However, this is not a real solution. Here is how it looks like:
[](https://i.stack.imgur.com/yAK0n.png)
Compare the result effect with the images above, and you will see the solution is still far away. So how can I properly get the desired effect using WPF? I'm fine with emulation (no use of `DrawThemeTextEx` API), as far as the result is pretty similar.
Thank you.

4,972,484 | 1 | 4,979,459 | null | 1 | 484 | Hello I added a JQuery SlideShow with 6 png images each with the size 548px X 320px
For some reason, sometimes when the page first loads these images appear very tiny. When I refresh the page, the images appear normal size. Again this doesnt happen every time. Im not sure if this could be a JavaScript error because when I run this in JFiddle there are JavaScript errors from the plugin's js file.
[http://jsfiddle.net/Mutant_Tractor/Re9pt/3/](http://jsfiddle.net/Mutant_Tractor/Re9pt/3/)
I've noticed on other sites that they implement some type of PreLoad(). I dont have that.
Here is the HTML:
```
<div id="top-feature">
<div class="slideshow">
<img alt="image1" src="images/slide1.png" />
<img alt="image2" src="images/slide2.png" />
<img alt="image3" src="images/slide3.png" />
<img alt="image4" src="images/slide4.png" />
<img alt="image5" src="images/slide5.png" />
<img alt="image6" src="images/slide6.png" />
</div>
```
Here is the CSS:
```
#top-feature {

margin: 12px 0 0 16px;

/*padding: 10px 0 0 10px;*/

4,972,930 | 1 | null | null | 2 | 337 | We have some 2d data parser that recives images of size 8x8 (roiSize=8) which are sent to our parser from something like:
```
void UseOurParser(IplImage* destination)
{
int w = destination->width;
int h = destination->height;
original = cvCreateImage(cvSize(w, h),IPL_DEPTH_8U,1);
cvCvtColor(destination,original,CV_RGB2GRAY);
cout << endl << "Progress:";
for(int j = 1; j < original->width/roiSize-1; j=j++) {
cout << "." ;
for(int i = 1; i < original->height/roiSize-1; i=i++) {
cvSetImageROI(original, cvRect(j*roiSize, i*roiSize,roiSize, roiSize));
IplImage *cropSource = cvCreateImage(cvGetSize(original), original->depth, original->nChannels);
cvCopy(original, cropSource, NULL);
ProcessOurParser(cropSource, j, i);
cvResetImageROI(original);
}
} //...
```
Our parser takes an image j, i and inside it can determine if an object was found on an image. And if it was found it performs another operation that determins some feature value (some float). I want somehow to create a 2d representation of my data (of size like (original->width/roiSize-2) X (original->height/roiSize-2)) so to each roi I'd have a value declaring if feature was found in it or not and if it was its feature value. What I need is to be capable to iterate through generated data. and implement some kind of region grouse algorithm so that if feature on one roi is == to feature on another that is one of 8 surrounding it we somehow grow region and check again and again so we find regions...
So if we were searching for lines and our features were bool for line existence and angle float (as I do) we would do something like
1) (we stand on blue 1 and 2 yellow 1s are points of our interest)
We submited to our "line" that 2 regions and continue searching
We found hat feature on one roi is related to our line and another is not so we will return to that roi later
so is there any help in boost on how to do such thing or any code help you can provide?

4,973,137 | 1 | null | null | 0 | 263 | We have some code inside our application that captures an image of a window and saves it to a PNG file and copies it to the clipboard (C++ API code).
Works perfectly on Windows XP. It also works on Windows 7, except that it looks as if the top few pixel lines of the image have been chopped off, as if the area that was captured did not include the top few lines of the window. Yet our code clearly copies from the top of the image, shown below.
(On Windows XP you see the full X on the right hand side plus the top border of the Window)
Is this some aero or other display effect on Windows 7, or is there a way to compensate for this?Or could something in our code possibly be causing this?
Sure, we can determine the window area and capture it from the client window, and capture a few lines higher up, but how may lines, and that seems arbitrary.
There must be some fundamental flaw or issue here?
Our code is roughly as follows:
```
RECT wndRect;
GetWindowRect(hwnd, &wndRect);
int Width = wndRect.right - wndRect.left;
int Height = wndRect.bottom - wndRect.top;
BYTE *pBits = 0;
BITMAPINFO bmpinfo = {sizeof(BITMAPINFO)};
bmpinfo.bmiHeader.biWidth = Width;
bmpinfo.bmiHeader.biHeight = Height;
bmpinfo.bmiHeader.biPlanes = 1;
bmpinfo.bmiHeader.biBitCount = 24;
bmpinfo.bmiHeader.biCompression = BI_RGB;
HBITMAP hBmp = CreateDIBSection(NULL, &bmpinfo, DIB_RGB_COLORS, (void**)&pBits, NULL, 0);
HDC hWndDC = GetWindowDC(hwnd);

4,973,401 | 1 | 4,975,595 | null | 12 | 1,897 | I am designing a little soccer game where the game engine (that computes player moves etc.) runs on a server, and rendering and keyboard/mouse handling is done by the client. For the server (Haskell) I want to use
- -
Every 20ms or so, the client should send keyboard and mouse events to the server via HTTP GET, receive the current game status (JSON-encoded ball and player positions) and render it. I am thinking about using SDL infrastructure for the game loop, input handling and rendering.
The server basically runs two threads: A happstack server receives the HTTP GET, puts the keyboard / mouse commands in a queue, reads the current game status from a second queue and answers the HTTP GET request.
The second thread runs a Yampa game engine, as described in the [Yampa Arcade paper](http://www.google.de/url?sa=t&source=web&cd=1&ved=0CBgQFjAA&url=http%3A%2F%2Fciteseerx.ist.psu.edu%2Fviewdoc%2Fdownload%3Fdoi%3D10.1.1.65.8016%26rep%3Drep1%26type%3Dpdf&ei=3Y5VTdOrBs74sgaQhJzmDA&usg=AFQjCNEIW_IZQ9qAg-Jc8RbGfx9981RJBw): The game engine computes the new round as quickly as possible (no ticks) and puts the result in the render queue.
General question: Does this look like a feasible architecture?
Specific question: How would one design the server side rendering queue: Would one use a Chan for this? If the game engine is quicker on average than the "ticking" on the client side, the queue will get longer and longer. How could this be handled with Chan?
Your comments are very welcome!

4,974,347 | 1 | null | null | 4 | 3,360 | I have a page setup that looks similar to this:
```
<body>
<div id="wrapper">
<!--- ... content ... -->
</div>
</body>
```
The body has a background color and a tiling image that adds some noise and grain to the background. On top of that, #wrapper has a linear gradient as background that goes from rgba(0,0,0,.3) to rgba(0,0,0,0) and the gradient expands over 24 pixels at the top of the div, which is at the top of the page --- to add a shadow.
My problem is, that the color that the background of #wrapper holds after the 24 pixel gradient is done, is not true transparency, even though the end color of the gradient has an alpha value of zero. What this leaves me with, is a not true transparent background on #wrapper, that leaves a visible "split-line" on the body-background at the spot where #wrapper stops.
How do I get the gradient to go in to full transparency? I would guess an alpha value of zero would do this. Also, using the `transparent` keyword doesn't solve it either.
I have added pictures to show the problem. The first picture is the actual look, and the second significantly shows where the line is, because it's there, though very unclear on the first picture.
As you can see, the gradient doesn't go in to true transparency. Not when the to-color is specified as `rgba(0,0,0,0)` or `transparent`.

4,975,713 | 1 | 4,975,762 | null | 1 | 10,741 | I am trying to create a blank database with mySQL Workbench that I can connect to with php. All this is on my local machine.
Here's what I think you do.
1. Click on Create New EER Model
2. Create a new Physical Schemata
3. Give it a name
4. Save Model to Current File
5. I think the name you add here is the database name?
However I can't connect to that name in php.
I have been trying this with a few options and one of them worked, but I can't see what's different about the ones that don't work.
There must be something very simple I am missing here.
eg this works:
```
$dbname = 'test';
$db = mysql_select_db($dbname);
echo '<br>db test is '.$db;
```

When compiled against Flex 4.1, this appears to create a memory leak, where ComboBoxView is never GC'd -- because of a lingering reference to the ComboBox.
Here's the output from the profiler:
Steps to reproduce:
- `Application.mxml``ComboBoxView.mxml`- - - - - - - -
Note - this doesn't occur when the application is compiled against Flex Hero.
It appears as though this is a bug, but I cannot believe that the ComboBox has a memory leak -- surely this would've been fixed before 4.1 was shipped?
What am I doing wrong here? Why isn't the view being GC'd?
I've done further investigation into this, and believe the issue lies in a problem with the RichEditableText component that the ComboBoxSkin uses. See details here:

4,976,202 | 1 | 4,976,258 | null | 1 | 2,830 | Got a question about C++ Pointer addition. If you look at the screen shot provided you can basically see I'm doing a memcpy(m_pBuf + m_iWritePtr .... and this memory pointer addition is not working as expected.
I had thought that the addition of m_pBuf + m_iWritePtr would add m_iWritePtr bytes to my memory address m_pBuf. m_pBuf is a pointer to a structure array; i.e. (T *)m_pBuf = new T[cnt] where T is a typename and cnt is the number of T objects allocated. T is, in this case a simple structure. The sizeof(T) in this case is 260.
The memcpy call is throwing a fault and I know my pointer math is wrong but I'm not 100% sure why. The memcpy is coded to, I thought, to take the base address and add some n * 260 bytes to get an offset into the buffer. NOTE: This code use to work when this was not a template implementation and T was simply a char *. Now that T is a template of some typename, the offset addition no longer works as expected.
So if you look at the screen shot below, here are the results of various calculations/references I did using the compiler's debugger/inspector and a calculator:
```
The memory address of m_pBuf = 0x01E7E0E0
The memory address of m_pBuf[1] = 0x01E8EE04
the memory address of m_pBuf+1 = 0x01E8EE04
the memory address of m_pBuf++ = 0x01E8EBFC
the memory address of m_pBuf+260 = 0x01E7E1E4 (the calculator's result)
```
I'm trying to understand what's going on here. The first two seem correct but I don't understand why none of these are equal. This is 32bit compiler on Windows 7-64bit.
To further explain, this is a ring buffer of type T with a size of n * T objects of storage. Here is the code:
```
template<typename T>
bool TMsgBuffer<T>::PutMsgEx(T *pBuf, unsigned long nObjCount )
{
bool bResult = false;
unsigned long MaxWriteSize, nPutLen;
Lock();
MaxWriteSize = GetMaxWriteSize(); // this returns size of my buffer in total.
nPutLen = nObjCount * m_nObjSize; // m_nObjSize is set else where to sizeof(T)
if(nPutLen <= MaxWriteSize)
{
// easy case, no wrapping
if( m_iWritePtr + nPutLen <= m_nBufSize )
{
memcpy(m_pBuf + m_iWritePtr, pBuf, nPutLen);
m_iWritePtr += nPutLen;
}
else // need to wrap
{
m_iFirstChunkSize = m_nBufSize - m_iWritePtr;
m_iSecondChunkSize = nPutLen - m_iFirstChunkSize;
memcpy(m_pBuf + m_iWritePtr, pBuf, m_iFirstChunkSize );
memcpy(m_pBuf, pBuf + m_iFirstChunkSize, m_iSecondChunkSize );
m_iWritePtr = m_iSecondChunkSize;
}
//m_MsgCount++;
m_MsgCount+= nObjCount;
bResult = true;
}
Unlock();
return bResult;
}

4,980,065 | 1 | 4,982,418 | null | 5 | 288 | I am currently implementing a 2D Range Tree. I am having trouble coming up with a plausible model (in Java) for my Node class.
A node in the tree may have any of the following: midrange value, right and left child pointer, subtree, data pointer and/or previous and next pointers.
I have broken down the Node into three separate logical pieces
- - -
I tried applying Composite and Decorator patterns, but to no avail.
I tried making:
1. Node interface with all the possible getters/setters, i.e.: getMidRange, getLeft, getRight, setLeft, setRight, etc...
2. Having two classes implement the interface: Node2D and LinkedNode (leaf node). Node2D did everything except keep the links to next and previous. While LinkedNode only kept links to next and previous.
It works like that, but I was wandering if there is a nicer way of modeling this as a set of classes?
EDIT: (short info): In range trees - all data is stored in the Leaf nodes, and the tree is always balanced. Furthermore all leafs are at the same height. Also, the leaves are sorted, and linked together by a doubly linked list. Last, but not least, each non-leaf node has a subtree - which is also a range tree, but with the leaves sorted on next attribute (say if original tree was sorted on ).

It's best to illustrate what I'm looking for.
Given these ViewModel classes:
```
namespace TreeViewSample
{
public class ApplicationViewModel
{
public ApplicationViewModel() { Projects = new List<ProjectViewModel>(); }
public IEnumerable<ProjectViewModel> Projects { get; set; }
}
public class ProjectViewModel
{
public ProjectViewModel() { Maps = new List<MapViewModel>(); }
public string Name { get; set; }
public IEnumerable<MapViewModel> Maps { get; set; }
}
public class MapViewModel
{
public MapViewModel() { Tables = new List<TableViewModel>(); }
public string Name { get; set; }
public IEnumerable<TableViewModel> Tables { get; set; }
}
public class TableViewModel
{
public TableViewModel() { Fields = new List<FieldViewModel>(); }
public string Name { get; set; }
public IEnumerable<FieldViewModel> Fields { get; set; }
}
public class FieldViewModel
{
public string Name { get; set; }
}
}
```
This is the result i want:
Can anyone help me with the XAML for this TreeView? I thought i understood how `HierarchicalDataTemplates` work, but the "static" container nodes ("Tables", "Fields", "Maps") seem to confuse me.

fold _ z Void = z
fold f z (Node x l r) = f x (fold f z l) (fold f z r)
```
The is to check that a node value is greater then all values in left-subtree and smaller than all values in its right-subtree. This must be `True` for all nodes in the tree. A function `bstList` simply output the list of (ordered) values in the BST.
Of course something like this won't work:
```
--isBST :: (Read a, Show a, Ord a) => BST a -> Bool
isBST t = fold (\x l r -> all (<x) (bstList l) && all (>x) (bstList r)) (True) t
```
because, for example, applying the fold function to the node `19` ends up `all (<19) (bstList True) && all (>19) (bstList True)`.

4,981,440 | 1 | 25,516,223 | null | 62 | 56,375 | I'm a bit confused as to how cookies work with Scrapy, and how you manage those cookies.
This is basically a simplified version of what I'm trying to do:
---
## The way the website works:
When you visit the website you get a session cookie.
When you make a search, the website remembers what you searched for, so when you do something like going to the next page of results, it knows the search it is dealing with.
---
## My script:
My spider has a start url of searchpage_url
The searchpage is requested by `parse()` and the search form response gets passed to `search_generator()`
`search_generator()` then `yield`s lots of search requests using `FormRequest` and the search form response.
Each of those FormRequests, and subsequent child requests need to have it's own session, so needs to have it's own individual cookiejar and it's own session cookie.
---
I've seen the section of the docs that talks about a meta option that stops cookies from being merged. What does that actually mean? Does it mean the spider that makes the request will have its own cookiejar for the rest of its life?
If the cookies are then on a per Spider level, then how does it work when multiple spiders are spawned? Is it possible to make only the first request generator spawn new spiders and make sure that from then on only that spider deals with future requests?
I assume I have to disable multiple concurrent requests.. otherwise one spider would be making multiple searches under the same session cookie, and future requests will only relate to the most recent search made?
I'm confused, any clarification would be greatly received!
---
## EDIT:
Another options I've just thought of is managing the session cookie completely manually, and passing it from one request to the other.
I suppose that would mean disabling cookies.. and then grabbing the session cookie from the search response, and passing it along to each subsequent request.
Is this what you should do in this situation?

4,981,764 | 1 | 4,982,098 | null | 4 | 1,933 | I have two area plots (call them 'blue' and 'green') where the `green` is mostly under the `blue` plot, but on a very few points, it is higher than the `blue` plot. I want to use transparency say `alpha = 0.2` for both, and also be able to specify the colors for each. My problem now is that since the `green` plot is mostly under the `blue` plot, its area mostly has the color `blue` + `green` = some other color, and in only a few places shows its "true" green color. However the of course shows the `blue` plot mapped to blue and the `green` plot mapped to green. Problem is, when someone looks at the graph, they will be confused since the `green` plot mostly looks non-green (because it's overlapping with blue most of the time).
Here's my code (super simplified version of my real application).
```
df <- data.frame( date = 1:5, blue = 10, green = c(1,5,11,5,1))
df.m <- melt( df, id = 'date', variable_name = 'type' )
df.m$type <- ordered( df.m$type, c('green', 'blue'))
ggplot(df.m, aes(date,value)) +
geom_area( aes(fill = type), position = 'identity', alpha = 0.2) +
scale_fill_manual ( values = c('green', 'blue') )
```
As you can see, the "true green" area of the green plot is very small, so the legend color for `green` doesn't really match the majority of the `green` plot. This is of course the right behavior by design, but I am wondering if there is some way I can get the legend colour for `green`, and the overlapping `blue+green` color to match up. One thing I did try is to transform the `blue` variable to `blue - green`, and then make the area plots (with `position = "stack"`). This almost works but isn't quite satisfactory because the color on the dates where the new `blue` variable is negative looks strange.
Are there other ways to get the legend color for `green` and the color of the "overlapping blue/green" area to match up? Maybe a way to directly specify the legend color? Any help appreciated!

And, here's what it looks like:
This is fine, except that the delete button on the right side is a little off from the row. This means that once we add ~13 or 14 rows, the delete button is way off from the row that it's going to be deleting. Thus, it's unclear to the user exactly which row will be removed when they hit remove.
I'd like to find some method that will allow me to align a button (or, in this case, a few buttons) with the row of the table in question, using CSS. Is this possible? I tried initially (without success) to do this without a second table, but that led me to the current situation, where I have a table for alignment purposes only on the right of the table that actually contains the data.
The big problem I'm faced with is that I can't seem to figure out how to align something with a row in a table. I could probably do it with jQuery, but this seems like taking a hammer to a screw. I'll admit I'm not as experienced at CSS as I am at programming, and so I usually tend to look to the programming answer. Can someone help me figure out how to have these buttons aligned correctly?
Thank you!

4,982,168 | 1 | 4,982,259 | null | 4 | 42 | I've been getting some odd behavior using a foreach today. I have a `dataset` that's pulling in a JSON document. Part of it is an array, which I `pick()` out and send to the foreach. Here's my global block:
```
global {
dataset appserver <- "http://imaj-app.lddi.org:8010/list/popular" cachable for 1 hour;
popular = appserver.pick("$..images")
}
```
There's one rule first that sets up the page. It looks like this:
```
rule setup {
select when web pageview "www\.google\.com"
pre {
imagelist = <<
<div id="462popular" style="margin-left:auto;margin-right:auto;width:450px">
<p>Popular images from the CS 462 <a href="http://imaj-web.lddi.org/">Image Project</a></p>
<span class="image"></span>
</div>
>>;
}
prepend('#footer', imagelist);
}
```
And here's the rule that's not working:
```
rule images {
select when web pageview "www\.google\.com"
foreach popular setting (image)
pre {
thumburl = image.pick("$..thumburl");
viewurl = "http://imaj-web.lddi.org/view?imagekey=" + image.pick("$..imagekey");
html = <<
<span class="image"><a href="#{viewurl}"><img src="#{thumburl}" style="border:none"/></a></span>
>>;
}
after('#462popular .image', html);
}
```
I get something like this (notice how small the scrollbar thumb is):
Any ideas what's going on here?

```
vsperfcmd /start:coverage /output:run.coverage

into C# code
```
// A guid is used to keep track of the run
Guid myrunguid = Guid.NewGuid();
Monitor m = new Monitor();
m.StartRunCoverage(myrunguid, "run.coverage");
// TODO: Launch some tests or something
// that can exercise myassembly.exe
// Complete the run
m.FinishRunCoverage(myrunguid);
```
For the `TODO:` part, I used this code
```
p = new Process();
p.StartInfo.FileName = "hello.exe";
p.Start();
p.WaitForExit();
// Look at return code – 0 for success
if (p.ExitCode != 0) {
Console.Error.WriteLine("Error in profiling");
System.Environment.Exit( -3 );
}
```
The code runs fine, but I can't the profiled result I did with running batch file.
This is the result from running batch file which has all the info.
This is the result from C# code which doesn't have profiled info, but only schema

4,982,485 | 1 | 4,991,131 | null | 4 | 1,832 | I'm using Ivy on my project, with the Ivy Eclipse plugin.
It appears that certain jars which are downloaded and added to my project are the javadoc jars, not the jars with the actual code. Note - this doesn't happen with all jars.
For example, adding this to my ivy.xml file:
```
<dependency org="junit" name="junit" rev="4.8.2"/>
```
caused the javadocs for junit to be downloaded and added to my classpath:
This breaks compilation for my project, as none of the unit tests are working.
This was working fine until I added a reference to Spring, and everything broke. I've tried removing the reference, and deleting junit from my local cache to force ivy to fetch it again, but the problem persists.

Which makes the JFileChooser dialog look , but still not native looking, and it ruins the rest off the application's feel too.
Thanks.

4,984,585 | 1 | null | null | 0 | 191 | I would like to list out all the students who have yet to pay off their course fee
i.e. when a student is clicked, list out all pending fees by months.
This is what I have done so far..
These are all the students active courses.
Below are the payments record paid by student to their course.
Now i would like to list out all the pending payment foreach students
e.g. last payment to the course is on 2/11/2011. If the datetime now is May, Then i would like to show the pending amount as
Month Amount
March 100
April 200
May 400
This is what I tried..
```
foreach (var result in activeCourses)
{
//Show all the pending paid coures from dateJoin till datetime.Now
DateTime JoinedDate = Convert.ToDateTime(result.cus.Date);
for (DateTime d = JoinedDate; d.Month <= DateTime.Now.Month; d = d.AddMonths(1))
{
Payment payment = new Payment();
payment.Course.Id = result.c.Id;
payment.Course.Name = result.c.Name;
payment.Course.Fee = result.c.Fee;
payment.CourseByStudent.CourseUserStatus.Date = result.cu.Date;
payment.CourseByTutor.TutorId = result.t.TutorId;
payment.User.Name = result.u.Name;
payment.MonthId = d.Month;
payment.MonthToPay = d.ToString("MMM");
output.Add(payment);
}
}
```
The logic given above does not seem to be efficient in case the student does not pay anything for his courses, then I have to check the pending payment since his first JoinedDate. OtherWise I need to check the pending payment from the DateIssue in the Payment table according to that particular course..please advice thanks

I also have to keep a running tally of the commission earned by each salesman until I hit clear, or exit the program.
When I hit the calculate commission, it of course should calculate the commission (which it does), but because the variables are method level (or some lower access level) and I can't seem to return them I can't pass the 2nd method the information it needs from the "...C" variables.

So there's a situation where there will be tons of dynamic form inputs. What do I mean by word "dynamic" is that - every attribute (form input) will be stored in table not as column but as value and name of form can be easily edited in the feature with out using migrations. Here's a scheme:
I want to have automatic modelform generated from this scheme. Django could just pick all field names/values/types from table1_attr table. And handle them as it's done with one-column-per-field scheme.
I know that it's possible to add any field later into the model, and then to use "south", but I really afraid of data migration with south. Because I had a lot of segfaults and errors before with this tool. Ofcourse this is an option, and if this scheme will fail - then I'll use usual solution. Btw middleware solutions also fine.
