What compiler are you using?

what version of VC++?

My guess is that you are writing a CLI/C++ program and Picture_viewer.h is using some unmanaged code. Here are some links that discuss that topic.

Read some of the links I posted. Most of the stuff in the Microsoft Windows SDK is unmanaged code.

I readed some of the links you posted but i am not trying to combine managed and unmanaged code.

I went to : project->add new item->forms

i made my form but now i want to include it in my first form so i can show it.

I've done that with VC++ 2010 Express and never had a problem. For some reason your compiler is attempting to get something from Microsoft Windows SDK that is installed on your computer.

I figure the problem out, i was including my form2.h at the top before windows.h, and other includes.
