It's a hard chore for a programmer to display string and integers in a message box, mainly because they have to use CString or sprintf to get these integers in formatted manner...

For eg:

int nAge = 27, nSal=100;
CString csStr;
csStr.Format( _T( "Age: %d, nSal: %d" ), nAge, nSal );
AfxMessageBox( csStr );


How can we automate this whole process? Here is the answer in the form of a function called ShowMsg.

For eg:

    // Shows dialog
void __cdecl ShowMsg( LPCTSTR lpctszTitle_i, const DWORD dwIconType_i, LPCTSTR lpctszMessage_i, ... )
{
        va_list vaArgList;
        va_start( vaArgList, lpctszMessage_i );

        CString csMsg;
        csMsg.FormatV( lpctszMessage_i, vaArgList );

        MessageBox( AfxGetMainWnd()->GetSafeHwnd(),
                    csMsg,
                    lpctszTitle_i,
                    dwIconType_i );

        va_end( vaArgList );
 
}// End ShowMsg

ShowMsg( _T( "Title" ), 
              MB_OK|MB_ICONINFORMATION, 
              _T( "My name is %s, my age is %d, my salary is %d" ), 
              _T( "Nibu babu thomas" ), 27, 100 );
