You aren't serious are you? This is elementary C++ programming. I strongly suggest you find a beginner C++ book and read it. In the meantime, these are overloaded functions. And the asterix means that the object being passed/returned is a "pointer." (I now feel like Dr. Evil explaining the obvious.) Anyone who thinks he has a better idea of what's good for people than people do is a swine. - P.J. O'Rourke

Erm...i'm nt too familiar with that...Could u elaborate? So do i need to specify where the message is sent to or where it is sent from etc? Thanks!

If you give it the BS_AUTOCHECKBOX style, it toggles automatically when you click. otherwise, as already said, it's internally a BUTTON class, you can query and change the check state with BM_SETCHECK and BM_GETCHECK (or CButton::SetCheck, GetCheck) "Vierteile den, der sie Hure schimpft mit einem türkischen Säbel." sighist | Agile Programming | doxygen

I see, au2B is defined like this, #define au2B( STUFF ) auT(STUFF) #define au2B( STUFF ) (LPTSTR)((LPCTSTR)STUFF) but i'm still not sure what that means...and why there are 2 definitions... Thanks for ur help guys...

Sounds like you have failed to add a closing brace for a function preceeding this one in the same file. void CComp::SomeFunction() { void CComp::OnSelchangeLUCOMPTop() { UpdateData(TRUE); Tselection1 = "Selection Changed"; CMain::uc_top = m_uc_ts.GetCurSel(); m_uc_epo.EnableWindow(TRUE); m_uc_epp.EnableWindow(TRUE); } Roger Allen Sonork 100.10016 Were you different as a kid?

If you are going to do a unicode project then all strings must begin with L eg. L"Part Files(*.asm)|*.sldasm||" to tell the compiler you want a wide string. But I would recommend you read up on TCHAR, that way you can compile your program in both UNICODE and single byte mode. I dont know any good unicode resource on the web, but if you are going to do a unicode project, then I recommend you read some books on the subject. Its a lot more to unicode than meets the eye.
