Class disappears in the class panel
I'm a VC++ starter. I try to program a simple program with some controls. But whenever I insert code(by double-clicking the control or use the Ctrl-W) for a specific control and compile the program. The class that contains the control disappears from the class panel(left panel of VC++6.0).
Sometimes I have an error message telling me that some files violated, or are used in some different programs. After I hit OK, the class that has that file disappears.
Could you please tell me how to fix this? It's so confusing.
Thank you for reading.
