every thing that I try does not work but if I compile the microsoft one it works fine. What would be differnt?

Very often when the texture doesn''t load it''s because you are using a relative path. You might not be in the directory that you are expecting.

try using getcwd(); to check where you are and see if the texture is in that directory.

I am not sure how to check if is loading or if it is loading properly and how do you use getcwd(); ?


1. Change:

To:
#pragma comment(lib, "d3dx8d.lib")

That''ll link your program with the DEBUG version of D3DX. If a D3DX call fails, it''ll report an error to the debug output window.


2.
a. Make sure you''ve installed the DEBUG version of the DirectX runtimes (you get the option when you install the SDK).

b. Make sure the debug D3D runtime is enabled in the DirectX Control Panel applet.

c. Increase the output level in the Direct3D tab of the DirectX Control Panel applet.


3. Run your application in the debugger (press F5 if you''re using MSVC). After the program has exhibited wrong behaviour, read through all of the text in debug output window (usually the bottom pane in MSVC). Any errors and warnings will be logged to there.

If you''re not using MSVC, you can use the debug viewer that comes with the DirectX SDK or download the one from www.sysinternals.com
