Introduction

Sometimes you might wish you could use other icons in a message box apart from the ones Windows gives you, or you might want to have more control over how your message box, specify which language to use, etc. Well, there is a way to do all this using the little-known API call MessageBoxIndirect.

Here is a class which encapsulates MessageBoxIndirect (actually, it inherits from the MESSAGEBOXPARAMS structure which you pass to MessageBoxIndirect). You can use it like an MFC CDialog, although there are no dependencies on MFC.

Usage

1. Declare a CMessageBox object.

#include "MessageBox.h"
....

CMessageBox box;

or

CMessageBox box(hWnd, "My Text", "My Caption", MB_OK);

2. Initialize it (If you are just displaying a standard Message Box you can skip this step

box.SetIcon(IDI_SOMEICON);
box.SetLangID(MAKELANGID(LANG_CHINESE, SUBLANG_CHINESE_TRADITIONAL));

3. Call DoModal.

if(box.DoModal() == MB_OK)
{
	// Do something here
}
else
{
	// Do something else
}

That's it!
