What could be wrong with my function :
In my log file I get the following error : Incorrect parameter in CreateDevice function
So is there something wrong in my d3dpp paramters or in my parameters in my CreateDevice() function?
thanx in advance
use == instead of = in your if block
if (hresult=D3DERR_INVALIDCALL) //error
if (hresult==D3DERR_INVALIDCALL) //correct
The Wild Wild West - Desperado!
if (hresult=D3DERR_INVALIDCALL) //error
if (hresult==D3DERR_INVALIDCALL) //correct

No, that isn''t the reason.
In
hresult=g_pD3D->CreateDevice(D3DADAPTER_DEFAULT, D3DDEVTYPE_HAL, g_hwnd, D3DCREATE_SOFTWARE_VERTEXPROCESSING, &d3dpp, &g_pd3dDevice);
One of the parameters passed is either missing, spelled incorrectly or need to be casted.

Wildwest is right tho. doing
if (hresult=D3DERR_INVALIDCALL)
{
}
will always execute the code inside. it''s because the = actually returns the value. so HRESULT becomes D3DERR_INVALIDCALL, and that is returned to the IF, evaluates to true, and writes to the log..
so change those too while you''re at it
