Display popup in Win32 Console Application

Question

How do I display a popup window in a Win32 Console application in Microsoft Visual C++? This is for building a drowsiness detection system using OpenCv.

Answer 1

MessageBox( nullptr, TEXT( "The driver is sleeping!!" ), TEXT( "Message" ), MB_OK );

Make sure to include windows.h. The thread you call this on will block.

Answer 2

#include <windows.h> 

int main() { 
        MessageBox(NULL, L"The message", L"The caption", MB_OK);

        return 0; 
} 

remember to link with user32.lib
