I created my texture in this way: if(FAILED(m_pd3dDevice->CreateTexture(256, 256, 0, 0, D3DFMT_P8, D3DPOOL_MANAGED, &m_pFiremap))) { return E_FAIL; } the parameter D3DFMT_P8, according to doc, defines the surface format as 8-bit color indexed. But I do not know why the value returned is E_FAIL. Can anyone give some ideas? Thanks for any help!!!

Switch to the debug runtime, and it should give you a hint.

Go to control panel, DX, D3D, and select use debug runtime. I also check ''break on assert'' box. If you don''t have DX in control panel, install debug runtime from the SDK.

even more weird thing happend: code that runs well under retail version now doen''t work under debug version. Here is the piece of code that failed:

if(FAILED(m_pd3dDevice->SetPaletteEntries(currIndex + 1 ,m_mypal)))
return E_FAIL;

Oh, and my original error still exists and I got no response at all from debug version???

Did you set ''debug output level'' slider to maximum?

Yes sir, not a bit of hint!!!

The function just returned a E_FAIL value and the program ends unexpectedly!!

You have to look in the debug output to see the information from D3D debug runtime. In MSVC6, use Alt+2.

I did what you told me to do and the output is faliure creating texture which does not help much.

Well, if the debug runtime gives you absolutely zero information, I''d say that your texture format is incompatible with your device. Try 16-bit or 32-bit ones.

I guess so, too. Thanks for your help!
