The code sample that follows shows the dialog box procedure for the application.

LRESULT CALLBACK AbortPrintJob(

        UINT message,     // type of message

        LPARAM lParam)    // message-specific information

    switch (message) 
    { 
        case WM_INITDIALOG:  / message: initialize dialog box 
 
            // Initialize the static text control. 
 
            SetDlgItemText(hwndDlg, IDD_FILE, ofn.lpstrFile);

        case WM_COMMAND:     // message: received a command 
 
            // User pressed "Cancel" button--stop print job. 
 
            MessageBox(hwndDlg, "Incoming", "WM_COMMAND", MB_OK); 
 
            bPrint = FALSE;
