I'm trying to convert the direct3d tutorials in the visual c directx SDK to asm files. I have working include files etc for directx 8, but I can't get the following code working:
All of the above code runs fine, the return values are correct and the directx interface works correctly, but the last coinvoke, with CreateDevice, always returns D3DERR_DRIVERINVALIDCALL. In the documentation only D3DERR_INVALIDCALL is mentioned (invalid parameter), but I can find NOTHING about D3DERR_DRIVERINVALIDCALL. The example in the tutorial works fine in visual C, and I compared the complete call to the interface in C and in asm, they are the same. What's the problem? Thomas
.data? g_pD3D dd ? d3ddm D3DDISPLAYMODE > d3dpp D3DPRESENT_PARAMETERS > g_pd3dDevice dd ? .code InitD3D proc hWnd:DWORD invoke Direct3DCreate8, D3D_SDK_VERSION mov g_pD3D, eax coinvoke g_pD3D, Direct3D8, GetAdapterDisplayMode, D3DADAPTER_DEFAULT, ADDR d3ddm mov d3dpp.Windowed, TRUE mov d3dpp.SwapEffect, D3DSWAPEFFECT_DISCARD mov eax, d3ddm.format mov d3dpp.BackBufferFormat, eax coinvoke g_pD3D, Direct3D8, CreateDevice, D3DADAPTER_DEFAULT, D3DDEVTYPE_HAL,\ hWnd, D3DCREATE_SOFTWARE_VERTEXPROCESSING, offset d3dpp, offset g_pd3dDevice .IF eax!=D3D_OK int 3 .ENDIF ret InitD3D endp
I figured out the problem. The structure definitions were wrong. Some structures had SDWORD members that were defined as SWORD types. It's possibly a bug in Amokila's tlb2inc tool. I have mailed him about the problem already. Thomas
I'm having the same problem - What structures did you have to change? (and what members) Thanks, Ryan Fairfax
Both D3DDISPLAYMODE and D3DPRESENT_PARAMETERS have wrong member types. all the SWORDs should be SDWORDs. But I think it's a bug in amokila's utility, so changing only that structures won't help for further errors. Thomas
Arg... the problem is that in idl uint variables and int variables have the same type : int !!! The only thing i can do is a dirty fix: add an option to treat int as SDWORDs. It should work knowing that for example for the dx8vb.dll there are are only UINTs not INTs... Any suggestions ?
You can get version 1.2.3 of Tlb2Inc with an extra option to treat INTs as SDWORDS here This message was edited by Amokila, on 4/11/2001 2:10:29 PM
