• Visual C++ bitmap colour depth

  hi Can anybody help me out with some example or implementation I want to convert a lower bit (8 or 16 or less than 24 bit) *.jpg file to 24 or higher bit jpeg file in VC++. Here is the little bit of detail what is actually happening. If I set color quality less than 24bit, in my system's display properties and then in my VC++ project, I save jpg file, it get saved as 0 byte file. but if somehow I can change the screen depth at the time of saving the jpg file, the problem can be solved.

• Game Technologies: DirectX, XNA, XACT, etc. Realtime debugging text?

  Hello. All I`d like to do is display crude text somewhere inside the game screen. Can I do this without having to load/use any type of font. The `Print` commands equivelant I suppose It`s just so I can see a variable changing during play. Please excuse this possibly mundane question but I`m fairly new to all this. -Daz. Console.Write() does not add a newline; you need Console.WriteLine() to actually flush a line to the debugger output window. Also note that the text will be sent to the "Output" window in the C# express solution -- not to your game window. If you want to draw text in a game window, then you must use some form of geometry. Either a texture with the alphabet in ...Show All

• Visual Studio Tools for Office Why do MS Word Automation return different values with and without Debugger?

• Visual Studio Cannot install VS 2005... UDF ISO-13346 issue

  Hey everyone, I'm having the devil of a time installing the VS trial version (team package) on my xp pro machine. I've been fiddling with it for the last 2 days and can't get the DVD to even recognize the UDF portion of the disc at all, which is where all the installation files are. argggg... I've tried extracting it with ISOBuster, which fails almost 1/3 of the way through. I've tried ripping it to an image with Nero and fails at 69%... And those are the only two programs that I have that will even recognize that there is a UDF partition on there... Explorer is clueless to its presence. Could anyone help me I would sooooo greatly appreciate. Thanks, Tim Although the workaround in my previous po ...Show All

• Visual Studio 2008 (Pre-release) Data binding with ObjectDataProvider and Collections

  First my apologies for the long post, but I'm running out of ideas here. In my application, I have a fairly large amount of application data that is being collected by worker threads. The data is collected in several custom classes and most of that information must be displayed on the UI. Some of the information is simple (strings, integers, etc.,...), but some of the custom classes would contain collections of other custom classes. My original thought was that data binding was a wonderful magical way of hooking all of this information up to the UI for display to the user, but as I understand more WPF's threading model for the UI and how the built-in data binding classes work I now realize it's a bit more complicated. I'm trying to use Obj ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. SimpleMesh game component and x2swm

  I've uploaded a SimpleMesh game component to use on conjunction with x2swm. Instructions are here: http://astaroth.beatbuggy.net:8080/Images/XNAMagic/SimpleMesh_GameComponent_rm.jpg Download it here: http://astaroth.beatbuggy.net:8080/Downloads/SimpleMesh_GameComponent.zip Instructions: 1) Add the game component to your project. 2) Drag the component onto your game designer. 3) Set the mesh path and mesh name. (i.e media\\ , Dwarf.swm) 4) Put the DrawComponents() call in whichever effect pass you wish. This works for n swm batches. It will continue to work if the texture is missing.

  I am using odbc driver to manipulate records to and from a Paradox database. In the Database I have two columns that are Paradox 5.0 memo fields, they have been formatted with a Rich Edit field in Delphi7 .

• Visual Studio 2008 (Pre-release) What is most efficient way to create the list of image thumbnails?

  Hi! I have a "little" question... ;) I would need to have (kind of) photo-album functionality in my application - it should display thumbnails of images from certain folder (and entering a folder with 2000 images should not bring the system to its knees!), and user should be able to move in that thumbnail view (using keyboard!) and perform some actions. Problem is, that there are so many options in all respects (what should be the container, how to get thumbnail of the images, how to do it asynchronous - so that folder with 2000 images would not block whole machine, etc.), that it is difficult to choose something In your opinion, what would be the most efficient way to do this Thank you very muc ...Show All

• Visual Studio Increasing the wait timeout for the VSS2005 Internet Web Service and IDE plug in

  Is there any way to adjust the time out parameters on the server and/or client side when using the Internet provider What's happening is that occassionally the connection between the developer and the server is a very slow one, and the plug in gives up (often at the worst of times), resulting in bindings getting confused. My client has also discovered that the server (Windows 2003) needs to be rebooted about once a week in order to keep the web service speed up. VSS2005 starts running slowly, they reboot the server, it speeds right up. VSS2005 is the only application hosted on the server at the moment.
