• Visual Studio 2008 (Pre-release) Styling Buttons using DependencyProperty

  I want to create an ImageButton that uses three bitmaps for its various states. So I've created a 'ImageButtonStyle' that replaces its ControlTemplate with a custom ContentPresenter. I use triggers on this style to check for the button state. To determine which bitmap i have to use for which state, I've created a ButtonInfo class that can hold 3 Uri's (for each state) and some more info, like for example the text and the foreground color. An instance of this custom class gets created for each button and assigned to the content of the button. I then use binding (in the ImageButtonStyle) to access the properties of the content. So far so good: this works. I can see the button with the bitmap and caption. The problem is that I want to make t ...Show All

• .NET Development DataTable - Null Object Reference Error

  We have a Multithreaded application where frequent updates will be done to Datatables either by adding or deleting or updating rows. As a precaution we lock the datatable to avoid any errors, but even after applying the lock mechanism on the datatable and when we make use of the Find method of the Rows collection of the database , we are flooded with the Null Object reference error.

• Visual C# Windows Form Location

  Hey everyone I've got just a quick question / problem. I'm making a new program, and in the constructor of the form, after the call to InitializeComponent(), I've got a call to: this.Location = new Point(0, 0); And the problem is that it does nothing. No matter what I do, I can't seem to change the form's location in the constructor. I've chucked a button on the form, and put an onClick to do the exact same location call, and it works there - just not in the constructor. Does anyone know how I can do this + why it won't work in the first place Thanks In the designer, change StartPosition (in your form) to Manual from whatever it is currently. Without that, Windows will default it to ...Show All

• Audio and Video Development Playing ASF files with third part content using WMP 11 / Vista

  Hello, I have generated some .ASF files containing a MPEG-4 video stream. I'm able to play these files with WMP 11 on Windows XP using a DMO without any problems. But when I try to play these files on Vista, WMP shows an error indicating that not decoder is available. (But I still can play them on graphedit using the DMO, so the DMO is registered) The question is: Is it required to convert the DMO to a MFT for being able to play ASF with third part content in WMP Or is just a bug in Vista Many thanks and regards ! /John Fredman     That's good to know. Sorry for giving you the wrong info then, John. I guess the authors of my DMO took that into account ...Show All

Thanks, JGP JGP, the subscriptions need to be added either using bissubscribe tool, or using client APIs (pointer in the post), and not directly in SQL.

• Visual Studio Yet another problem with symbols

  Right, so I've used VS in the past with no problem, but I was working with C# and today I was looking to code port a portion of code into C++.  As I have visual studio professional 2005 Team Edition installed (College is great) in my lab, I was looking to use it.  For this piece of code I really need to be able to use the debugger and step into the code as the language the file was written in is far different (ever heard of IDL ). Now, I've spent four hours trying to solve this problem, and it's starting to annoy me.  It loads the file when I go into the debugger, but as other people have had, it displays the breakpoint won't be hit, no symbols are loaded.  Now, I opened up the modules window for the debugger and it ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. OpenGL wglCreateContext fails when rendering onto a bitmap when not having rendered onto a window first

  Hi, I'm having a frustrating problem with the wglCreateContext call. I'm using DirectX for rendering on screen, and I'm using OpenGL to render the same thing onto a bitmap (for printing). When not using DirectX, the OpenGL bitmap creation works fine, but when using DirectX, the wglCreateContext call fails and GetLastError returns 8 ("Not enough storage is available to process this command"). Anybody got any thoughts on this A number of calls are succeeding before this call fails: getting the screen DC, CreateDIBSection, SetPixelFormat all succeed. All help is appreciated! Wout I'm just getting more insight in what the problem is. It doesn't have to do anything with DirectX, the problem seems t ...Show All
