I did the following:
I made an import library for d3d9.dll with one export
_Direct3DCreate9 4 = Direct3DCreate9

Now, every time I call the function, I get a Win32 exeption.
I just want to know why.

Did you call CoInitialize before calling the DirectX function ?

No, I didn't. But now it works without it!
I forgot the "return" and the compiler didn't complain, because I had a "return
E_FAIL" in an if-block

Not needed when using the *Create functions of DirectX. You only need 
CoInitialize when loading manually through the COM interface. The 
*Create functions are essentially wrappers for that.
