Hello,

I wrote a windows application using VC++, in the program form and  I use 1
tab control that contains many tab pages.I hope to control navigation on
these tabpages by pressing a certian button, hide and show specfic tab pages
according to the user actions by pressing another special button , and
include an exit button in some of these tabpages.

I have some functions in a C++ file that i want to use them in my program.

I have some questions I will appreciate your help on them.
1/ How can I exit from a VC++ windows application programmatically?
2/ How can I navigate from a tab page to another in the same tab control
during run time?
3/ How can I hide and show a certian tab page from the tab control in the
run time according to the user choice?
4/ How can I include a C++ file in a VC++ program to use function that
written in C++ file?

Thanks in advance.
