Add Waiting Cursor/Dialog in MFC project and add some error control

Hi, I have a small MFC application. I need to do the following: 1. Add a progress dialog when a function is executed and freeze the main window until done (plus a couple of seconds). 2. Show a progress cursor when on function is executed. 3. Do an error control. I am in an hurry to get this done. Preferably today. Sincerely
