1,260,670 | 1 | null | null | 4 | 10,472 | I would like to create an application with rich UI elements and no VCL in Delphi (except a TForm). Each components (buttons, list, etc...) needs to support full per pixel alpha and be easily created without any codes. It should be skinnable and able to give result similar to adobe air application.
I've tried with GR32 (Graphics32), but each instance of TImage32 take too much memory.
Do you know any frameworks or components for Delphi 2009 that would allow me create a set of components for making rich UI application ?
Cheers!
I would like to have similar result but without using a TImage32 for each components (buttons, labels, panels, etc...)

1,263,973 | 1 | 1,269,863 | null | 1 | 3,625 | I am able to draw a sprite on the screen of an iPhone, but when I try to rotate it I am getting some weird results. It seems to be stretching the sprite in the y direction more the closer the sprite gets to pointing down the y-axis (90 and 270 degrees). It displays correctly when pointing down the x and -x axes (0 and 180 degrees). It is basically like it is shearing instead of rotating. Here are the essentials of the code (projection matrix is ortho):
```
glPushMatrix();
glLoadIdentity();
glTranslatef( position.x, position.y, -1.0f );
glRotatef( rotation, 0.0f, 0.0f, 1.0f );
glScalef( halfSize.x, halfSize.y, 1.0f );
vertices[0] = 1.0f;
vertices[1] = 1.0f;
vertices[2] = 0.0f;
vertices[3] = 1.0f;
vertices[4] = -1.0f;
vertices[5] = 0.0f;
vertices[6] = -1.0f;
vertices[7] = 1.0f;
vertices[8] = 0.0f;
vertices[9] = -1.0f;
vertices[10] = -1.0f;
vertices[11] = 0.0f;
glVertexPointer( 3, GL_FLOAT, 0, vertices );
glDrawArrays( GL_TRIANGLE_STRIP, 0, 4 );
glPopMatrix();
```
Can anybody explain to me how to fix this please?
halfsize is just half the x and y extent of the sprite; removing the glScalef call does not make any difference.
Here is my matrix setup:
```
glMatrixMode(GL_PROJECTION);
glLoadIdentity();
glOrthof(0, 320, 480, 0, 0.01, 5);
glMatrixMode(GL_MODELVIEW);
glLoadIdentity();
```
OK, hopefully this screenshot will demonstrate what's happening:

1,266,709 | 1 | 1,266,822 | null | 4 | 2,800 | I have written an implementation of the A* search algorithm. The problem is that the heuristic I'm currently using only works accurately on square grids. As my map is isometric, the heuristic doesn't take into account the layout of the map and thus, the distance between cells.
After extensive logging and analysis (read as ), I have come to the conclusion that my current heuristic works quite well, with one little exception: the end result is reversed for straight and diagonal movement.
```
inline int Pathfinder::calculateDistanceEstimate(const CellCoord& coord) const
{
int diagonal = std::min(abs(coord.x-goal->position.x), abs(coord.y-goal->position.y));
int straight = (abs(coord.x-goal->position.x) + abs(coord.y-goal->position.y));
return 14 * diagonal + 10 * (straight - 2 * diagonal);
}
```
This means that a straight move, which really costs `sqrt(2)` times more than a diagonal move on an map, is calculated to be the that of a diagonal one. The question is: how can I modify my current heuristic so it will produce correct results for an isometric layout? Simply replacing `diagonal` with `straight` and vice versa will work.

1,270,078 | 1 | 1,270,813 | null | 22 | 14,542 | I am attempting to write a simple WPF learning project which creates a set of buttons inside a resizeable main window. There is to be one `Button` per entry in a collection, and the contents of that collection may vary during run-time. I want the buttons to fill the entire window (e.g. 1 button @ 100% width, 2 buttons @ 50% width, 3 buttons @ 33% width, etc. all at 100% height). A simplified version of what I've written so far is:
```
<ItemsControl x:Name="itemscontrolButtons" ItemsSource="{Binding}">
<ItemsControl.ItemTemplate>
<DataTemplate>
<Button Tag="{Binding}">
<TextBlock Text="{Binding}" />
</Button>
</DataTemplate>
</ItemsControl.ItemTemplate>
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<StackPanel Orientation="Horizontal" />
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
</ItemsControl>
...
List<string> listButtonTexts = new List<string>() { "Button1", "Button2" };
...
itemscontrolButtons.DataContext = listButtonTexts;
```
This results in this:
I have been unable to make the buttons stretch to fit the width and my attempts to use a `Grid` instead of `StackPanel` were fruitless.
Then, as an optional improvement, I would appreciate suggestions on how to adjust it such that if there are so many buttons that they cannot fit properly on a line or are narrower than a threshold, it will wrap onto a new line (thereby halving the button heights if going from 1 to 2 rows).
I'd like to emphasize that I'd like to know how to do this the . I realize I can consume window resize messages and resize the controls explicitly, and that's how I'd have done it with MFC or WinForms, but from what I've read that is not how such things should be done with WPF.

1,273,428 | 1 | 1,348,248 | null | 13 | 11,750 | I am using the jquery-ui slider as a sideways scroll bar, and am having issues with the fact the handle slides beyond the end gutter (it can be seen [here](http://jqueryui.com/demos/slider/) if you slide the slider the farthest to the right). I have tried everything I can think of with CSS to try to get the handle to go no further than the gutter, but to no avail. Any suggestions would be greatly appreciated.
To clarify I am adding the following diagram which shows the problem (it is very subtle since the handle is small, however if you create a large handle in CSS, the handle goes half its width beyond the gutter).
[Here](http://jsbin.com/inome/edit) is a jsbin of the problem. Basically I want the handle to stay within the gutter.

I've attempted the following:
- 2 TTrackbars: 1 for min, 1 for max- 2 TTackbars: 1 for min, 1 for range- 2 TSpinEdit controls to type the numbers manually- 
1 TTrackbar control, with a little button to switch between min-mode and max-mode. In min-mode I set selStart and in max-mode I set selEnd (with ShowSelRange set to true).
Most options take more screen estate than I'd like, and they are not intuitive.
Ideally, I'd like something that works like the scrollbar in Sony ACID. You can click and drag 3 different points to the min, max, or both:
Is there any Free component available to set a range, or can something similar be done by using out-of-the-box VCL components creatively?

I've modified TMkRangeSlider to suit my needs. It works like a charm now. I've sent the modified component and demo to the original author.

Figure 1.8(b) models a network of
roads as a graph, where the vertices
are cities and the edges are roads
connecting pairs of cities. Graphs are
likely the object in question whenever
you seek a “network,” “circuit,”
“web,” or “relationship.”
Figure 1.8(b) is this:

Is there some sort of jQuery plugin that exists for this? If there isn't a plugin, is there some easy way to draw lines that would be snap-able? Is there algorithm for dealing with calculating points and working out which lines to create?

string[] visualizable = collection.ConvertToVisualizableList();
Dictionary<string,string> dic = new Dictionary<string,string>
{
{"key1","value"},

};
string[,] visualizable2 = dic.ConvertToVisualizableDictionary();
}
static string[] ConvertToVisualizableList(this IList collection)
{

{
if (collection == null) return null;
int length = collection.Count;

int length = dictionary.Count;
string[,] list = new string[length, 2];
int i = 0;
foreach (object item in dictionary.Keys)
{
list[i, 0] = item.ToString();
object value = dictionary[item];
if(value!=null) list[i, 1] = value.ToString();
i++;
}
return list;
}
}
}
```
These are VS visualizers for array and multidimentional arrays:
I want to use something similar for ICollection (or IList), IDictionary etc.
Note that in arrays, the visualizer shows every nested objcet.

Try to visualize a List and you will see that there is a private value _items, so you can see its items.

1,297,107 | 1 | 1,297,468 | null | 3 | 389 | I'm using the current jQuery to hide fade out a notification div, and then remove it, however when it completes there's an odd gap around the height of a ` ` - meaning that subsequent forms and page elements don't display where they were before the notice appeared.
To recap: the fade out and remove is working perfectly but I'd like the gap left over to vanish as well. It's a minor thing, but it's bothering me.
The jquery:
```
// Fade out any success divs.
$(".success").fadeOut(6000, function(){
$(".success").remove();
});
```
The notification div is being written by PHP on postback, and has the following CSS:
```
.success {
background-color: #b3ffb2;
border: 1px solid green;
}
.box {
margin: 5px;
padding: 5px;
}
```
The div is very simple:
```
<div class="success box"><p><strong>Success!</strong><br />Done!</p></div>
```
Edit: The surrounding markup of the page looks like this:
```
<div id="wrapper">
<div id="navigation">
<ul> ... </ul>
</div>
<div id="container">
<div class="success box">
<p><strong>Sucess!</strong><br />
Done</p>
</div>
// more content
</div>
</div>
```
Edit: Using Firebug in FF 3.5.2, I can't see anything being left behind using the inspector. There's just an odd gap. I've also created a screenshot of this phenomena:

The problem is that it shows for about 2 seconds, and then the page is posted-back before the user can make a selection on the popup. I've set a breakpoint on that event handler, and indeed the page is posted back.
How can I have the post-back delayed while the user makes up their mind and clicks on the OK or Cancel button on the popup?

1,299,887 | 1 | null | null | 2 | 1,036 | By modifying the `RowStyle` of a `DataGrid` I have created a customized grid that will display some buttons at the end of the row when the mouse hovers above the row:
I created a new style for `DataGridRow` based on the default style. I then modified the XAML to add my buttons inside a `StackPanel` (details omitted):
```
<UserControl.Resources>
<Style x:Key="DataGridRowStyle" TargetType="swcd:DataGridRow">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="swcd:DataGridRow">
...
<StackPanel x:Name="RowControlsPanel">
<Button>
... these are the buttons displayed on the row
```
The `DataGrid` is modified using the style:
```
<swcd:DataGrid RowStyle="{StaticResource DataGridRowStyle}">
...
</swcd:DataGrid>
```
I want to create another grid in a similar manner, but with a different set of buttons at the end of the row. I could create a textual copy of my style and modify it accordingly, but I was hoping that I could create a proper reusable class. I'm not sure how to approach this since the stuff I want to factor out of my style is a collection of controls (buttons) inside a style.
My approach so far is to create a `MyDataGrid` class derived from `DataGrid`. I have added a new property `RowControls` to `MyDataGrid` enabling me to instantiate it like this:
```
<local:MyDataGrid>
<local:MyDataGrid.RowControls>
<Button>
... these controls should go at the end of the row
</local:MyDataGrid.RowControls>
...
</local:MyDataGrid>
```
`MyDataGrid` uses a `RowStyle` as described above. But how do the contents of the `MyDataGrid.RowControls` collection get into the `Content` of `RowControlsPanel` in the style? I think I should do that in `OnApplyTemplate` of the `DataGridRow`, but then I need to derive a new `MyDataGridRow` class from `DataGridRow`. Unfortunately it seems that `DataGrid` is hardcoded to use `DataGridRow` and I'm not able to inject my own derived row class. I get the feeling that I need to approach my problem of reuse in a different manner, but I'm not sure how?
Customizing simple controls like buttons by adding new properties and modifying the control template is quite easy, but how do I customize a complex control like `DataGrid` where the template I need to customize is nested inside the grid?

1,303,893 | 1 | 1,305,637 | null | 2 | 2,744 | This is super in-depth. I understand if you don't even want to read this, this is mostly for me to sort out my thought process.
Okay, so here's what I'm trying to do. I've got these objects:
When you click on one (or select several) it should display their properties on the right (as shown). When you edit said properties it should update the internal variables immediately.
I'm trying to decide on the best way to do this. I figure the selected objects should be stored as a list of pointers. It's either that, or have an isSelected bool on each object, and then iterate over all of them, ignoring the non-selected ones, which is just inefficient. So we click on one, or select several, and then the selectedObjects list is populated. We then need to display the properties. To keep things simple for the time being, we'll assume that all objects are of the same type (share the same set of properties). Since there aren't any instance-specific properties, I figure we should probably store these properties as static variables inside the Object class. Properties basically just have a name (like "Allow Sleep"). There is one PropertyManager for each type of property (int,bool,double). PropertyManagers store the values for properties of their respective type (this is all from the Qt API). Unfortunately, because PropertyManagers are required to create Properties I can't really decouple the two. I suppose this means that I have to place the PropertyManagers with the Properties (as static variables). This means we have one set of properties, and one set of property managers to manage the variables in the objects. Each property manager can only have one callback. That means this callback has to update the properties of its respective type, for objects (a nested loop). This yields something like this (in pseudo-code):
```
function valueChanged(property, value) {
if(property == xPosProp) {
foreach(selectedObj as obj) {
obj->setXPos(value);
}
} else if(property == ...
```
Which already bothers me a little bit, because we're using if statements where we shouldn't need them. The way around this would be to create a different property manager for every single property, so that we can have unique callbacks. This also means we need two objects for each property, but it might be a price worth paying for cleaner code (I really don't know what the performance costs are right now, but as I know you'll also say -- optimize when it becomes a problem). So then we end up with a ton of callbacks:
```
function xPosChanged(property, value) {
foreach(selectedObj as obj) {
obj->setXPos(value);
}
}
```
Which eliminates the entire if/else garbage but adds a dozen more event-listeners. Let's assume I go with this method. So now we had a wad of static Properties, along with their corresponding static PropertyManagers. Presumably I'd store the list of selected objects as Object::selectedObjects too since they're used in all the event callbacks, which logically belong in the object class. So then we have a wad of static event callbacks too. That's all fine and dandy.
So now when you edit a property, we can update the interal variables for all the selected objects via the event callback. But what happens when the internal variable is updated via some other means, how do we update the property? This happens to be a physics simulator, so all the objects will have many of their variables continuously updated. I can't add callbacks for these because the physics is handled by another 3rd party library. I guess this means I just have to assume all the variables been changed after each time step. So after each time step, I have to update all the properties for all the selected objects. Fine, I can do that.
Last issue (I hope), is what values should we display when multiple objects are selected an there is an inconsistency? I guess my options are to leave it blank/0 or display a random object's properties. I don't think one option is much better than the other, but hopefully Qt provides a method to highlight such properties so that I can at least notify the user. So how do I figure out which properties to "highlight"? I guess I iterate over all the selected objects, and all their properties, compare them, and as soon as there is a mismatch I can highlight it. So to clarify, upon selected some objects:
1. add all objects to a selectedObjects list
2. populate the properties editor
3. find which properties have identical values and update the editor appropriately
I think I should store the properties in a list too so that I can just push the whole list onto the properties editor rather than adding each property individually. Should allow for more flexibility down the road I think.
I think that about covers it... I'm still not certain how I feel about having so many static variables, and a semi-singleton class (the static variables would be initialized once when the first object is created I guess). But I don't see a better solution.
Please post your thoughts if you actually read this. I guess that's not really a question, so let me rephrase for the haters, (or something along those lines).
---
Looks like I need to clarify. By "property" I mean like "Allow Sleeping", or "Velocity" -- all objects have these properties -- their VALUES however, are unique to each instance. hold the string that needs to be displayed, the valid range for the values, and all the widget info. are the objects that actually hold the value. They control the callbacks, and the value that's displayed. There is also another copy of the value, that's actually used "internally" by the other 3rd party physics library.
---
Trying to actually implement this madness now. I have an EditorView (the black area drawing area in the image) which catches the mouseClick event. The mouseClick events then tells the physics simulator to query all the bodies at the cursor. Each physics body stores a reference (a void pointer!) back to my object class. The pointers get casted back to objects get pushed onto a list of selected objects. The EditorView then sends out a signal. The EditorWindow then catches this signal and passes it over to the PropertiesWindow along with the selected objects. Now the PropertiesWindow needs to query the objects for a list of properties to display... and that's as far as I've gotten so far. Mind boggling!

1,304,809 | 1 | null | null | 1 | 7,135 | I have an article that I want to publish on my Joomla! site. Every time I click apply or save. I get error `500 - An error has occurred! DB function reports no errors`. I have no idea why this error comes up, al I can think is that it's a server error.
I'm using TinyMCE to type articles together with Joomla! 1.5.11.
Updated: I turned on Maximum error reporting in Joomla! and in the article manager I tried to save the article and got these couple of errors. Please check screenshot
I tried adding
```
<?php
ini_set('error_reporting', E_ALL);
error_reporting(E_ALL);
ini_set('log_errors',TRUE);
ini_set('html_errors',TRUE);
ini_set('display_errors',true);
?>
```
at the top of the index.php pages for Joomla! but it does not show any errors. I checked the error logs on the server and also no errors come up.
I managed to publish the article via phpMyAdmin but then something else happens. I try to access to article from the front end, by clicking on the link to the article, but only a blank page comes up.
This is really weird, since the error log does not show any information. So I assume the error needs to be coming from Joomla!
This happens if I add a print_r($_POST) before `if (!$row->check()) {` on /administrator/components/com_content/controller.php (around line 693)

The issue I am running in to is that for an ellipse, the arc drawn does not match up with what I would expect.
For example, the following code generates the image below. The green circles are where I would expect the end points of the arc to be using the formula for a point along an ellipse. My formula works for circles but not for ellipses.
Does this have something to do with polar versus Cartesian coordinates?

float y = (float)(( bounds.Y + b ) + b * Math.Sin(angleInRadians));

<%= Html.ValidationMessage("ReleaseDate", "*") %>
</p>
<p>
<%= Html.Submit("Create") %>

and here is the code that handles the validation logic:
```
public bool ValidateMovie(Movie movieToValidate)
{
if (movieToValidate.Title.Trim().Length == 0)
_validationDictionary.AddError("Title", "Title is required.");
if (movieToValidate.Director.Trim().Length == 0)
_validationDictionary.AddError("Director", "Director is required.");
if (movieToValidate.ReleaseDate.ToString().Trim().Length == 0)
_validationDictionary.AddError("ReleaseDate", "Release Date is required.");
return _validationDictionary.IsValid;
}
```
I assumed that the key value for the validation dictionary needed to correspond with the value that is provided for the field (ReleaseDate in this case), but that does not seem to be happening for me. I also tried adding a space in between the words, in case it was looking for it by display name, but no luck there either.
Can anyone help me out on this one?
## Edit
Following [Joseph's suggestion](https://stackoverflow.com/questions/1312648/why-is-my-validation-message-generic-asp-net-mvc/1312694#1312694), I stepped through the application to see where the other validation error was happening. Unfortunately, I found no clues...at least apparent to me. Here is a screenshot of my watch window:
As expected, there are three keys in there: Title, Directory, and Release Date. No sign of the fourth (third in the list? see first screenshot) validation failure.

[Overlapping Lines](https://imgur.com/wJ8uz.png)
The box surrounds most of the line [(tx,midy)-(sx,midy)] that has overlapped an existing line (represented by `psegment` in the code below). I have removed the overlapping arrow heads (and tails) and am a little stumped on how to check for overlap.
Here is the problematic code:
```
Line2D.Double segment = new Line2D.Double( sx, midy, tx, midy );
// Associate the middle-y point with the bounds of the target object.
// On subsequent draws of targets with a similar mid-y, make sure that
// there are no overlapping lines.
//
if( midPointMap.put( midy, segment ) != null ) {
//if( midy == 90 ) {
// New Line.
//
System.err.printf( "NEW: (%3.2f, %3d)-(%3.2f, %3d)\n", sx, midy, tx,
midy );
for( Line2D.Double psegment : midPointMap.getValues( midy ) ) {
// Previous Line.
//
System.err.printf( "OLD: (%3.2f, %3d)-(%3.2f, %3d)\n",
psegment.getX1(), midy, psegment.getX2(), midy );
}
//}
}
// Line for the bus.
//
result.moveTo( sx, midy );
result.lineTo( tx, midy );
```
Here is another example image to give you an idea of the Manhattan layout:
In the figure immediately above, the line between Dialog and Window has been overlapped (not quite visible at this zoom). The image illustrates how there can be multiple subclasses, and so detecting overlap must take into consideration multiple targets (tx, ty) for multiple sources (sx, sy) along the same mid-y line.
The `midPointMap` variable is a hash set that can contain multiple values per key:
```
private MultiValueMap<Integer, Line2D.Double> midPointMap =
new MultiValueMap<Integer, Line2D.Double>();
```
This maps mid-y values against a set of line segments.
Any ideas how to not draw the line if it overlaps an existing line segment?
Note that line segments for each "bus" are given in no particular order.

1,324,544 | 1 | 1,325,601 | null | 1 | 1,454 | I plan on having to split up the Geometry object into a series of simpler shapes, and combine their centroids using this formula:
Mathematical details of this formula can be found in [this Wikipedia article](http://en.wikipedia.org/wiki/Centroid#Centroid_by_geometric_decomposition).
Don't be suprised if my view of the mathematics is incorrect. I haven't done any complex math past trigonometry, and I've never had to deal with Greek letters. I think I understand this one pretty well, but please just let me know if I've got it wrong.
: the centroid of a gometric shape or prism is not just the middle of the shape. It is the center of gravity, or center of mass. I assume that Geometry objects can encapsulate 3D prisms as well, so I may have to take this into account in the future, but for now I'm focusing on 2D Geometries only. For a 2D shape you have to imagine it being a stiff piece of paper with a given shape, and the centroid would be the point at which this piece of paper would balance on a needle.
The first problem I'm faced with is that I need to find a way to accurately split any given Geometry object into simple-enough shapes, so this formula can work correctly. Does anyone have any ideas how this might be accomplished? Or is there a better procedure that will still work universally?
The second problem I'm faced with is that after the geometry is split up, how do I go about finding the centroid of each piece? Each type of simple shape (triangle, quadrilateral, semicircle, etc) has its own centroid formula. Is there a way for me to figure which type of shape each piece is?

1,325,758 | 1 | 1,325,940 | null | 0 | 562 | Slightly related to [this question](https://stackoverflow.com/questions/1303893/properties-editor-design-pattern/1305637#1305637), but you don't really need to read that. The screenshot is helpful though:
So what's happening is when you click an object, change a property, deselect it and then reselect it, the property editor will be reset to all 0s, even though those aren't the actual values. When you actually click in the text boxes in the editor, the correct value appears. Does that mean it's just a display issue or what? How come the editor has two different values? The code:
```
void PropertyBrowser::objectUpdated() {
if(m_selectedObjects.isEmpty()) {
return;
}
m_variantManager->disconnect(this); // <--- THIS LINE
QMapIterator<QtProperty*, QByteArray> i(m_propertyMap);
bool diff;
while(i.hasNext()) {
i.next();
diff = false;
for(int j = 1; j < m_selectedObjects.size(); ++j) {
if(m_selectedObjects.at(j)->property(i.value()) != m_selectedObjects.at(j - 1)->property(i.value())) {
diff = true;
break;
}
}
if(diff) setBackgroundColor(topLevelItem(i.key()), QColor(232,232,232));
else setBackgroundColor(topLevelItem(i.key()), Qt::white);
m_variantManager->setValue(i.key(), m_selectedObjects.first()->property(i.value()));
}
connect(m_variantManager, SIGNAL(valueChanged(QtProperty*, QVariant)),
this, SLOT(valueChanged(QtProperty*, QVariant))); // <--- AND THIS LINE
}
```
However, I need those lines because they prevent `setValue` from triggering a `valueChanged` signal which causes other issues. This seems to indicate that calls this function fixes the issue:
```
void PropertyBrowser::valueChanged(QtProperty *property, const QVariant &value) {
if(m_propertyMap.find(property) != m_propertyMap.end()) {
foreach(QObject *obj, m_selectedObjects) {
obj->setProperty(m_propertyMap[property], value);
}
}
}
```
But the only thing that THAT function does is update the actual object... it has nothing to do with the property editor (or shouldn't). Here's the entire class if you need it:

}

}
}

}

```
It's otherwise a very cool class if you want to use it. Let's you edit the properties of any QObject given that they have Q_PROPERTYs attached.

1,327,442 | 1 | 2,817,528 | null | 1 | 696 | I am working on an ASP.NET 2.0 web solution which currently runs en-GB and zh-HK languages as the 2 current languages for the site. Others will be added at a later date.
One of the requirements is that the user can choose to override the language displayed to another language. Therefore users in Hong Kong can view the site in English and vice versa.
My 2 resource files are
- -
The site performs this logic
1. Load user details
2. Check if user has overridden the preferred language
3. If they have, set the Thread.CurrentThread.CurrentUICulture to this language.
4. If they haven't, use the browsers default.
This is implemented in the following code:
```
//This method is written in a base page, which all pages in the site derive from
protected override void InitializeCulture()
{
User user = /*Load custom user object...*/;
string threadLanguage = Thread.CurrentThread.CurrentUICulture.IetfLanguageTag;
//If the browser is using a different language,
//but the has chosen a preferred language,
//change the CurrentUICulture over.
if (!threadLanguage.Equals(user.Language, StringComparison.OrdinalIgnoreCase))
{
CultureInfo userLanguageCulture = CultureInfo.CreateSpecificCulture(user.Language);
Thread.CurrentThread.CurrentUICulture = userLanguageCulture;
}
base.InitializeCulture();
}
```
I have also configured the web.config to pick up the uiCulture automatically with
```
<globalization uiCulture="auto"/>
```
For some very very odd reason, some users (even en-GB users) are finding the language is switching over the zh-HK for no reason whatsoever - sometimes between pages! I have added some debugging code to these pages which should reveal more information in the coming days. All it has revealed so far is that users are not necessarily from zh-HK, some are from zh-CN or zh-TW. Although this might help, because en-GB users are seeing zh-HK I think it is just a red herring.
What I have noticed is that the switch over occurs on page content (those inheriting from the base page, which the IntializeCulture() method exists). The custom user controls I have written do not experience this problem and appear in the correct language configured by the user. Therefore a page would have combinations of both English and Chinese content - eek!
Can anyone give guidance as to if I am coding this correctly, or an alternative way of approaching the requirements.
Thanks in advance,
Dominic
P.S. This is an intermittent problem and not a permanent. There seems to be no common action that replicates this issue. It just - happens.
P.P.S Here is an image of the problem in action:
---
Update 23 Sep 09:
After trying to change it to Page.Culture, I am still having more intermittent problems.
I have a couple of ideas at why this could possibly be occurring, but am unable to justify my 'hypothesis':
- - -
Apart from that, I do not know what else could cause the problem. I would show another screenshot, but the problem is identical and did appear in the same place as the previous screenshot showed.
Update 25 Sep 09:
I think we I might have solved it. In our Web.config, there is a tag that was configured as follows:
```
<globalization uiCulture="auto" culture="auto"/>
```
After removing that, after initial testing, it has yet to turn up!
Update 13 Oct 09:
The problem has turned up again :-(
Update 26 Oct 09:
It seems that if another user of the site changes their preferred language, it affects all other users on the site! Although their preferred language is set, somehow someone else's language switch affects the other users of the site!

1,329,527 | 1 | 1,329,579 | null | 2 | 1,909 | In our application we're using [jdMenu plugin](http://jdsharp.us/jQuery/plugins/jdMenu/) to create a hierarchical menu from nested unordered lists.
This works well until there are so many items in a menu that it is forced off the screen.
In an attempt to fix this I've updated the plugin (actually the positionBy plugin that is a requirement of jdMenu) so that when a long menu is discovered the plugin reduces the height of the menu (ul), applies overflow:hidden and attempts to place it again. It then attaches a mousemove event to the menu so that when the users moves their mouse up and down the menu scrolls allowing them to see the hidden items. Like so:
(print screen doesn't capture pointer but on the left screen it's at the top of the menu, on the right it's at the bottom)
This works when it is the last menu in the hierarchy that is too long as above, however if a menu further up the hierarchy is too long then it's sub-menus are not displayed because of the overflow:hidden which has been applied.
So, my question is... is there another way to achieve this effect without using overflow:hidden (or can I use it in a better way)?
Alternatively, is there a more suitable jQuery plugin which will allow me to do something similar?
Let me know if you need any further clarification. Thanks loads.

1,341,183 | 1 | 1,341,478 | null | 2 | 905 | I am working with SiteFinity CMS. My particular layout is 3-column with 100% width (side columns are fixed width, center is fluid). In the center column, I want to divide it up into multiple "boxes" using CSS. My first attempt was with [960 Grid System](http://960.gs). Here is the markup that I used:
```
<div class="container_12">
<div class="grid_12">
<div class="grid_5 alpha tl">
<p class="tlc">
<asp:ContentPlaceHolder ID="TopLeftBox" runat="server" />
</p>

</div>
<div class="grid_5 omega tr">
<p class="trc">
<asp:ContentPlaceHolder ID="TopRightBox" runat="server" />
</p>
</div>
<div class="clear">

<div class="grid_5 alpha bl">

<div class="grid_5 omega br">
<p class="brc">
<asp:ContentPlaceHolder ID="BottomRightBox" runat="server" />
</p>
</div>
</div>
</div>
```
Here is a screenshot of the result:
However, if I utilize the additional class tags (`tl`, `tr`, etc) and add padding, this is what happens:
Here is the CSS I used to add the padding:
```
.tl
{
background-color:#EEEEEE;
padding:5px;
}
.tr
{
background-color:#DDDDDD;
padding:5px;
}
```
I imagine that this is because of conflicting CSS, since both SiteFinity and 960gs have their own distinct style sheets.
Can anyone provide me with some additional insight about why this is happening, and possibly how to get these two to work together nicely?
Thanks!
## EDIT:
So I added the following CSS:
```
.tl
{
background-color:#EEEEEE;
margin:-5px;
padding:5px;
margin-bottom:25px;
margin-top:15px;
}
.tr
{
background-color:#DDDDDD;
margin:-5px;
padding:5px;
margin-bottom:25px;
margin-top:15px;
}
/* I am almost ashamed of how ugly this CSS is */
```
To me, this seems like a duct-tape fix. Any feedback on this?

But I'd like to get this information in code (sort of like Python's `id` function), so I could very easily trace how objects move through out the system. For example, I might have:
```
trace("Returning", id(foo));
```
Then somewhere else I could use:
```
trace("Using", id(foo));
```
To make sure both bits of code are dealing with the same instance.
Now, I know that many AS classes implement the `IUID` interface... But there are also a bunch of classes which don't (plain old arrays and objects, for example), so that wouldn't solve my problem.
I realize that I could also wrap objects in an `ObjectProxy`, but that would be less than ideal as well.

1,345,473 | 1 | 1,345,944 | null | 9 | 13,173 | I am using jQuery 1.3.2.
There is an input field in a form.
Clicking on the input field opens a div as a dropdown. The div contains a list of items. As the list size is large there is a vertical scrollbar in the div.
To close the dropdown when clicked outside, there is a blur event on the input field.
Now the problem is:
In chrome(2.0.172) when we click on the scrollbar, the input field will loose focus.
And now if you click outside, then the dropdown won't close(as the input has already lost focus when you clicked on the srollbar)
In Firefox(3.5), IE(8), opera(9.64), safari() when we click on the scrollbar the input field will not loose focus. Hence when you click outside (after clicking on the srollbar) the dropdown will close. This is the expected behaviour.
So In chrome once the scrollbar is clicked, and then if I click outside the dropdown won't close.

I'm using DirectShow.net to get webcam footage into my program.
To accomplish this, I'm adding the source camera to the graph, and a VideoMixingRenderer9.
That part is all working swimmingly, but the part where I extract a frame using GetCurrentImage(out lpDib) is having what I can only describe as an odd issue.
What I am doing is using Marshal.PtrToSTructure to create a BitmapInfoHeader from lpDib, then calculating the width / height / stride / & pixel format.
The problem comes when I look at the image stored in bitmap - It has a 10 px wide line down the left side that came from what is actually the right!
It is worth noting that the data I am getting from the GetCurrentImage call is actually upside down - note the call to Cap.RotateFlip.
```
IntPtr lpDib;
windowlessCtrl.GetCurrentImage(out lpDib);
BitmapInfoHeader head;
head = (BitmapInfoHeader)Marshal.PtrToStructure(lpDib, typeof(BitmapInfoHeader));
int width = head.Width;
int height = head.Height;
int stride = width * (head.BitCount / 8);
PixelFormat pixelFormat = PixelFormat.Format24bppRgb;
switch (head.BitCount)
{
case 24: pixelFormat = PixelFormat.Format24bppRgb; break;
case 32: pixelFormat = PixelFormat.Format32bppRgb; break;
case 48: pixelFormat = PixelFormat.Format48bppRgb; break;
default: throw new Exception("Unknown BitCount");
}
Cap = new Bitmap(width, height, stride, pixelFormat, lpDib);
Cap.RotateFlip(RotateFlipType.RotateNoneFlipY);
//if we examine Cap here (Cap.Save, for example) I'm seeing the odd stripe.
```
I'm completely lost here. Seems like some sort of offset issue, and I've tried tweaking with stride some, but to no avail (just creates odd diagonal look).

1,358,896 | 1 | 1,364,430 | null | 0 | 255 | I've been stumbling over this for a while and was wondering if anyone has run into this problem before.
The application I'm working on is divided into multiple data plots and a single timeline at the bottom of the screen. Each plot (which is actually multiple textures layered on top of each other) as well as the timeline is rendered to a separate texture. The timeline texture is rendered first, followed by each of the plot textures from the top of the screen to the bottom. I am using DXUT and DirectX9 (March 2009).
After adding time text to the timeline texture, I noticed that the text was repeated in the title bar of every data plot. Here's a screencap of a portion of the display, it shows just a single plot, but the text repeats on every plot opened:
It seems like it is tied directly to the DrawText being called in the timeline's render function. I do use relative coordinates as the rect being passed to DrawText, but since I've already set the render target to the desired texture it should only affect the current texture. Not every texture rendered afterward.
Has anyone ever run into any problems similar to this using D3DXFont?
: After some more experimentation, it looks like it has something to do with the Z buffer. By adding D3DCLEAR_ZBUFFER to the clear on each texture surface, the duplicate text is gone. While the problem seems bypassed for now, I'm still curious as to why the Z buffer for a completely separate texture was being written during my DrawText call.

[clLocationManager startUpdatingLocation];
} else {

Any idea on waht I'm doing wrong?

My problem is that I have 2 tables Folder and Item with a many to many relationsship using a third "connection" table FolderItem like this:
[](https://i.stack.imgur.com/Sl0ld.png)
[InsomniacGeek.com](https://InsomniacGeek.com/Downloads/Model1.png)
In the .NET RIA Service domain service, I want to create a method that returns all Items for a given FolderID.
In T-SQL , that would something like this:
```
SELECT * FROM Item i
INNER JOIN FolderItem fi ON fi.ItemID = i.ID
WHERE fi.FolderID = 123
```
My Linq knowledge is limited, but I want to do something like this:
```
public IQueryable<Item> GetItems(int folderID)
{
return this.Context.Items.Where(it => it.FolderItem.ID == folderID);
}
```
This is not the correct syntax, it gives this error:
> Cannot convert lambda expression to
type 'string' because it is not a
delegate type
What is the correct way of doing this (with associations) ?
Can I user the .Include("FolderItem") somehow?
Please, method syntax only.
PS.
Here's how it would look like using a Query Expression:
```
public IQueryable<Item> GetItemsByFolderID(int folderID)
{
return from it in this.Context.Items
from fi in it.FolderItem
where fi.Folder.ID == folderID
select it;
}

1,370,486 | 1 | 1,370,541 | null | 0 | 466 | I have a PHP calendar that lists all of the days of the month in a table. Before the first day of the month I have numbers from the prior month and after the last day of the month are the numbers of the days for the upcoming month.
Here's a photo of the Calendar as it currently looks. As you can see the bottom gray numbers are working fine, but the numbers preceding the first day of the month are negative numbers and should instead appear as '29,30'
The numbers after the last day of the month were simply '32,33,34' for example, so I just created an if statement that checks if the number is greater than the total numbers of days in the current month and if so, then subtract the total numbers of days in the month from '32' for example, which would then make it appear as '1,2,3'.
```
if ($day > $total_days_of_current_month) {
echo '<td>' . ($day - $total_days_of_current_month) . ' </td>'; // for example,33-31=2
}
```
My problem is creating an if statement that somehow knows what the last days of the prior month was. The problem is that some months have 30 days and some have 31 days. Also, the month of February and leap years are a problem. Does anyone know an if statement so i can make it appear as '28,29,30' from the previous month?

I use the project plugin to keep a window up on the left side of my gVim screen, listing my projects. It's handy and keeps me from going into IDE withdraw. Here's an idea of what it looks like:
I then invoke NERDTree on the right side with <Leader>][:
I then navigate through NERDTree to find whatever I was looking for, and dismiss NERDTree with <Leader>][. This makes the NERDTree window go away, but rather than put the main window back to the size it was, it grows the project window instead:
Right now I manually resize the project window, but that really interrupts the flow I'm trying to achieve with vim.
I'm using gvim 7.2, NERDTree 3.1.1, and project 1.4.1. Anyone have any ideas how to fix this?
: Based on Steve K's answer I've figured out the solution. When you run the `:Project` command and it creates the project window, the project window is the active one. So I just added `set winfixwidth` to my `.vimrc` after `:Project`, and that solved the problem. Now I can show and hide NERDtree to my heart's content with no annoying window resizing.

1,374,380 | 1 | null | null | 13 | 5,904 | Have looked through the other questions and can't see a clear answer to this.
We are a small development team, working on what could be described as 3 separate front-office 'applications' (OnlineOrders via asp web, TradeManagement winforms app, ASP.NET ReportingSuite).
However for better or worse, each of these apps share one central SQL2005 database, let's call it MainDB. They all use the same Orders table structure, the Users, the Accounts etc., pretty much 80% of the objects are used in some way by each of the apps.
In TFS, I had thought that each of these 3 apps as being seperate Projects, with the Work Item tracking, reporting etc that would give us. Seemed to work fine getting our 'code based' Solutions created.
Now I'm trying to see how I can get the MainDB database into TFS Source Control. I can't see an obvious way to do this.
:
Am I supposed to create a database project for MainDB, export the schema into scripts in the project, and add that database project into each Solution, inside each TFS Project?
Or should I have a separate TFS Project just for my database project? And a developer would have to open both the MainDB database TFS Project and (eg) the TradeManagement TFS Project open to develop a new feature (as most new features will involve some db changes too)? Seems very heavy handed.
Or is it common to just have one massive TFS Project, called 'Everything', and within that have feature branches for the code projects, and a database branch for the database, and any other projects that might use the MainDB database? (in the img, assume MainDB scripts are in the 'Database' folder)
etc. Man, I am confused. Codeplex seems to point to keeping it simple by putting all solutions inside on big single solution. Is that sustainable?
---
Thanks for the responses, really great.
The idea of treating the database as an API is interesting, it is really like that. The database is populated from numerous sources, some internal, some external, some apps get data out that was input via another app. Controlling it as an API that each app dips in and out of is a very helpful analogy, thanks for that.
The cost of having no support for dependencies is a concern, but I think we can be disciplined enough to do our branching in an orderly manner. The branching of the app codebase is likely to be more involved than the database - we really just want the database under source control in some way to satisfy Sarbannes-Oxley audit requirements.
I will have to think some more on this.
The horizontal partitioning of the db isn't something I'd considered. It feels like too much of the database objects are shared to be able to chop it into horizontal blocks - we'd have the same objects (tables/sprocs etc) in several blocks which I think would confuse us further.

1,376,504 | 1 | 1,376,654 | null | 3 | 908 | I have been working on designing a file server that could take the load off from the primary website, and serve images/files over the web to the client.
Primary goals of the file server:
- Take off load from primary server hosting the site
- Reuse the existing web server code base and avoid duplication of code/logic for better maintainability
- Being scalable for increasing downloads
- Hide real download url path from user
By keeping above in mind, i could come up with two approaches. Sequence diagram representation of the two approaches for ease of understanding [apologies for the skewed use of sequence diagram]. Neither of the approaches would satisfy all my goals.
Which of these approaches would you recommend considering my goals?
Is there a better third approach?
Some of the differences, i could think of:
- Approach #1 would result in duplicating BL code causing maintainability issues
- Approach #2 would reuse code and centralize BL reducing maintainability issues
- Approach #1 would reduce network calls while #2 increases them
The concept of file servers, scalability of downloads, bandwidth distribution have all been there for a while now. Please share your thoughts!
UPDATED:
Approach #1 looks very attractive as it takes the load off the primary server completely. The only issue to address in #1 is the code duplication and maintainability issues. This could be overcome by having just one project for BL/DAC comprising the functionality required by both web service and file server. And, reference the assembly/library in both web service and file server projects. Now, there is only one BL/DAC code to maintain and also avoids the network calls in approach #2.

And other smaller "boxes" that act as containers for particular things inside of the content "Box".

We want to replace our existing Java portal with a Django application, which means duplicating the Java portal's ability to display portlets. The two Sun specifications in question that we want to duplicate are JSR168 and JSR286.
I need a cPython solution. Not Jython or Java. Nothing against those tools, we just don't use them. For the record, the Jython based [Portletpy](http://code.google.com/p/portletpy/) does the opposite of what we are aiming to do.
Also, I suspect this question has been caused by a misunderstanding on our part of how the JSR168/JSR286 specification works. I that JSR168/JSR286 is an arcane protocol for communicating some sort of content between separate applications, but in the Java world that tends to be done by other methods such as SOAP. Instead, the issue might be that these protocols are simply definitions of how to display content objects in views. If all we have to do is handle SOAP calls and display data, then this whole question is moot.

Many Google results have pointed towards setting the GridViewColumn.CellTemplate to change the appearance of a column. However, I'm met with an issue when setting the background color; it's not stretching to fill the cell:

</Grid>
</DataTemplate>
</GridViewColumn.CellTemplate>
</GridViewColumn>
</GridView>
</ListView.View>
</ListView>

```
And the xaml.cs for good measure:
```
public partial class Window1 : Window
{
public Window1()
{
InitializeComponent();
DataContext = new[]
{
new {FirstName = "Jim", LastName = "Bob"},
new {FirstName = "Frank", LastName = "Smith"},
new {FirstName = "Tooth", LastName = "Paste"},
};
}
}
```
Setting the DataTemplate's Grid's width and height to be larger than the cell with a negative margin can produce a close result, but if you resize the column, the problem shows itself again.
```

The thick skeleton lines in the middle of the leaf is what need to be visualized.

Here's what the control lag looks like; this occurs when I resize the window by its top border (recorded with a camera because screen-cap made it less obvious by making everything slow):
Example of the black border: this was captured while resizing the window; it's only like this for a split second but it's very noticeable:
Am I doing something wrong? How can I have my controls stay visually in one place during resizes? How can I avoid the black border?

1,386,598 | 1 | 1,391,904 | null | 2 | 2,922 | I'm using the IOBluetooth Cocoa framework to communicate with a bluetooth device. So far I have gotten down the whole process of discovering the device and its services, pairing with it, connecting to it and now I want to send some actual commands, but I'm having some trouble with it. Below is an graphic from the spec for the AVRCP profile that I'm trying to use. You can [view the pdf here](http://www.bluetooth.com/nr/rdonlyres/0cd6930c-302e-4bb8-aca8-199066b47ade/922/avrcpspecv10.pdf).
I believe I need to write an 5 byte value as shown by the image:
Here is the method I have right now that writes the data:
```
- (void)l2capChannelOpenComplete:(IOBluetoothL2CAPChannel*)l2capChannel status:(IOReturn)error {
NSLog(@"Open Complete");
NSMutableData *playData = [[NSMutableData alloc] initWithCapacity:5];
unsigned char ctype = 0x0;
unsigned char subunit = 0x90;
unsigned char opcode = 0x7C;
unsigned char opid = 0x44;
unsigned char opdata = 0x0;
[playData appendBytes:&ctype length:8];
[playData appendBytes:&subunit length:8];
[playData appendBytes:&opcode length:8];
[playData appendBytes:&opid length:8];
[playData appendBytes:&opdata length:8];
usleep(1000);
[l2capChannel writeAsync:[playData mutableBytes] length:40 refcon:nil];
}
```
When that function runs the devices responds with the following hexadecimal value 0x400010.
1. I'm not even sure I'm approaching this correctly!
2. Are the values I'm sending correct according the example in the image?
3. Any help in my endeavor to learn here would be much appreciated!

1,389,057 | 1 | null | null | 4 | 8,664 | I'm having trouble with a WCF service. The return type is a semi-complex type which makes reference to various basic types and a base interface that each of those types inherits from.
In my debugging, the total byte size of the serialized message is well under the default 65535 byte threshold. Nevertheless, I have increased the maxReceivedMessageSize attribute to 1000000 and the problem remains.

Note that I have removed the Render() overrides from the abstract implementations of NoteSegment for the sake of readability.
Any insight into what I might be doing wrong here would be appreciated. A Google search yields little in the way of useful answers.

1,390,437 | 1 | 1,390,458 | null | 0 | 2,060 | I am seeing some odd behavior in SQL Server [AVG](http://msdn.microsoft.com/en-us/library/ms177677.aspx) calcuation.
On manual calculation, you get `49.277588`
but SQL Server is reporting that the average is `50.9914`
as shown below.
Can someone explain the difference and why this is happening?
You can try out the query on AdventureWorks2008 Database with following query
```
select C.ProductCategoryID, P.ProductSubcategoryID,
AVG(P.ListPrice) as 'Average',
MIN(P.ListPrice) as 'Miniumum',
MAX(P.ListPrice) as 'Maximum'
from Production.Product P
join Production.ProductSubcategory S
on S.ProductSubcategoryID = P.ProductSubcategoryID
join Production.ProductCategory C
on C.ProductCategoryID = S.ProductCategoryID
where P.ListPrice <> 0
group by C.ProductCategoryID, P.ProductSubcategoryID
with rollup
```
