Homework problem perhaps?

jhance - yes it's homework, but at least Azadeh isn't asking someone to do it for them.

Azadeh - most people (certainly most beginners) writing dialogs in VC++ will use MFC, which makes doing these things easier.  Do you intend to use it?  If so, you could do this:

Select File->New.
Seleect the projects tab in the App wizard.
Select MFC Appwizard(exe)
Select Dialog based
Click finish.

You will now be shown a dialog resource, which is where you build your dialog.  Try compiling and running it now.

The dialog will be based on the CDialog class, and will be called C[name of app]Dlg.  Look for it in the class view.  Try adding the buttons you need to the dialog resource, double click on them and the wizard will add functions to the ...Dlg class to handle the clicking.

Perhaps you've done all of that, and all you need to know is how to access the other code you've written?  Well, you will/should have declared the functions in a header (.h) file, and defined them in an implementation (.c/.cpp/.cc) file.  Add both of those files to the project, and declare in the Dlg file (probably the .cpp) that you want to use the functions:

#include "MyHeader.h"

If you have any other problems, ask.
