I used the appwizard to create an SDI where I changed the base class of CView to CEditView. So, a text file passed as a command-line argument will display and be editable(by default). I have a text file that is accessed and changed from other sources on my network. I have the timer in MainFrm set to go off every 3 secs. I need to know how and where to close the file, so that the timer can reload it.
