  That's a lot of code. Which line is your error in And why can't you use VC2003 ( you should be able to )

  i know c++ pretty well and i got started into directx. im using dev-c++ for it and when i compile the following code i get a: invalid conversion from `void*' to `HINSTANCE__*' error. wat does this mean and how do i fix it other people got the code to work so wat did i leave out

  It means your code has supplied a void pointer value where an HINSTANCE value was expected. You'll need to look at the line in your code where the error is to find out what the exact problem is.

  dev-c++ isnt visual. its a different compiler but its made for programming stuff like this. and yea i got da sdk installed. im using dev-c++ because when i try to build on visual it says that my version of visual-c++ doesnt support the optimied compiler or sumtin like that. its visual 2003 though.

  what code :-) Is dev-C++ a visual C++ version, or a different compiler altogether Do you have the DirectX SDK installed
