question about message boxes

[php]
#include <windows.h> // include the basic windows header file

// the entry point for any Windows program
int WINAPI WinMain(HINSTANCE hInstance,
HINSTANCE hPrevInstance,
LPSTR lpCmdLine,
int nShowCmd)
{
// create a "Hello World" message box using MessageBox()
MessageBox(NULL,
L"Hello World!",
L"Just another Hello World program!",
MB_ICONEXCLAMATION | MB_CANCELTRYCONTINUE);

return 0;
}
[/php]

How do I make stuff happen when yes, no, cancel is pushed?

I know it would have to do with the if statement but where would I use it? just getting into windows programming now. (skipped void, classes and all that stuff for now, going to get back to it tomorow)

MSDN is your god: http://msdn.microsoft.com/en-us/libr...8VS.85%29.aspx

If a message box has a Cancel button, the function returns the IDCANCEL value if either the ESC key is pressed or the Cancel button is selected. If the message box has no Cancel button, pressing ESC has no effect.

If the function fails, the return value is zero. To get extended error information, call GetLastError.

If the function succeeds, the return value is one of the following menu-item values.
