Split win32 gui project

[acidvertigo]

Hello,
i'm building a project using the windows application wizard and selecting the "hello word" template.

what i want is to split main.c file so every dialog functions are in separate c files as i have to build a big menu for my application.

For example if i remove the last AboutDlgProc function from the main file and move to another aboutdlg.c file is a good practice to declare the function prototype as external in the main.c file as follows?:

Code: [Select]

extern LRESULT WINAPI AboutDlgProc(HWND, UINT, WPARAM, LPARAM);

Seems that this link has the correct answer: http://c-faq.com/cpp/hfiles.html

So is best to put the external prototype in the header file. Just sharing here for beginners like me.

Yes, you're right.
The prototypes are normally put in header files (.h).
