Basic Windows Dialog (tested in Win 3.1)

#include <windows.h>
#include <stdio.h>


int main()
{
    int msgboxID = MessageBox(
        NULL,
        "Do you want a\nFart Box?",
        "Question",
        MB_YESNO
    );

    switch (msgboxID)
    {
    case IDYES:
    MessageBox(NULL,"FART","FART BOX",MB_OK);
        break;
    case IDNO:
    MessageBox(NULL,"Nothing to Smell Here","My Message",MB_OK);
        break;
    }

    return 0;
}
