P.S. this is a dll...it may sound crazy, but for my purposes i need it to be a dll...

You didn't add in the D3D library correctly.

#pragma comment("<dllname>")

if I'm not mistaken...

[UserLoser.]

Code Select Expand


#pragma comment(lib, "d3d9.lib")
#pragma comment(lib, "d3dx9d.lib")
#pragma comment(lib, "dxguid.lib")


Not sure if the last one is needed, but doesn't hurt to link to it

Yep, I was mistaken :\
