I'm using MS VC++ 5.0 to program an SDI with a custom dialog box containing an edit box. I've declared the new class for the dialog box & declared a variable associated with the edit box.
I need to display data obtained in the OnKeyDown function from the View class, into the (disabled) edit box - which is, of course, in the Dialog class. Since I need a new variable available to both classes. I thought I'd use an external variable in a new header file & #include in both class .cpps.
However, I get an "unresolved external symbol" error! Any ideas?
