Cancel Dialog Box
The Cancel dialog box typically contains a single push button that allows the
user to cancel a print job. The following template for the Cancel dialog box
was taken from the sample application's resource (.RES) file.
AbortDlg DIALOG LOADONCALL MOVEABLE DISCARDABLE 33, 32, 160, 70

{
switch (message) {
case WM_INITDIALOG: /* message: initialize dialog box */
/* Initialize the static text control. */
SetDlgItemText(hwndDlg, IDD_FILE, ofn.lpstrFile);
return TRUE;
case WM_COMMAND: /* message: received a command */
/* User pressed "Cancel" button--stop print job. */
MessageBox(hwndDlg, "Incoming", "WM_COMMAND", MB_OK);
bPrint = FALSE;
