Hi, i am new to the environment and i have 2 basic questions 1) isn't it possible to use directdraw from a C program? I have a basic dd application which draws some bmp's to the screen, i can compile it with ".cpp" extension but i cant compile with the extension ".c". As far as i can see i am not using any cpp structures , classes or something like that. With .c extension the compiler identifies dd objects such as IDirectDrawSurface7 but it cannot find some of its methods such as Release(). *using vc++ 6 2) I needed to rearrange the code as a dll.I moved the init,deinit and drawing sections to the dll. It gives about 2 fps.(It was 75 without the dll). I did lots of changes but i got stuck with 2 fps. Am i missing something here or is this normal? thanks in advance Mete

C++ is, in reality an extension of C. The extension of the file (".cpp"), makes no to your C code, and is probably left there. DirectDraw uses OOP, so that might be why your extension is causing it grief, but once again, best leave it as .cpp.

As for the second question, you should be geting faster results than that.
