What type of application did you create?
How did you create it? Did you use App Wizard?

i used the app wizard to create a dialog based app. app interfaces with matlab to plot graph. Now i am getting the above mentioned error. i haven't included the commctrl.h and prsht.h files in the project.

WHat IDE are you using?
Do you use precompiled header files? If not then did you #include <windows.h>?

What version of Visual C++ are you using?
