Tricks with D3DX10GetImageInfoFromResource

  • 项目

I am playing with D3D10 tonight, and I am trying to get D3DX10GetImageInfoFromResource to work for me. I have beaten on it for a long time, and it still resists my powers.

On a whim I write some code to call FindResource myself to make sure that I can find the resource and it works, but that makes me think about the resource types on this page:

https://msdn.microsoft.com/library/default.asp?url=/library/en-us/winui/winui/WindowsUserInterface/Resources/IntroductiontoResources/resourcereference/resourcetypes.asp

And then I remember that some other D3D resource functions like resources to be in RC_RCDATA format. Lo and behold, this is the problem - I had a bmp file as a resource, but it was marked with RC_BITMAP!

Lesson learned - D3D loads RC_RCDATA resources, even when they are bitmaps. I hope this saves somebody some time one day :)

    Yep.  Most things that load resources have some specific list of types they support.  It's not always clear what those types are from the documentation, unfortunately. For example, IE's res:// protocol only supports RT_HTML or RT_FILE.  I spent a few hours debugging the same thing to discover that.  :)

    A great many thanks!I spent hours on this. I thought I had created a bitmap in RC_RCDATA using the bitmap import  button and never saw that it created an RC_BITMAP resource. After reading your comments I went back and noticed where it was located. Now it works!!!Thanks again,Paul Roussin
