[Question 12]: How to clean and delete a class
[answer]
How to completely delete a class when programming with VC? We can do this:
First, remove the corresponding .h and .cpp file from the FileView in Workspace; then turn off the project, remove the corresponding .h and .cpp file from the actual folder; then delete the .clw file. Since then, open the project, Rebuild All. In this way, we thoroughly remove a class that useless to us.
[Question 13]: How to solve the VC incorrect connection problem
[answer]
When using the VC development project, this will often encounter this situation: clearly changed only a file, but all the entire project is re-connected once. Just connected, once, and prompt to recompile the connection once, very annoying. This is because there is a future file.
We can deal with it: find out the DEBUG directory under the corresponding folder, create and modify the time than the system time late DELETE, then Rebuild All. Everything will be OK.

Save Workspace first, then turn off the project, delete the .ncb file in this project directory, and then reopen Workspace.
