hello guys, I am new in VC++, and I am using Sams Teach yourself C++ in 21 days Book, I find these book complicated and with too many errors on its codes. I tried to call another dialog windows and this error occured. C:\Program Files\Microsoft Visual Studio\MyProjects\Dialogs\DialogsDlg.cpp(297) : error C2039: ''m_iOption'' : is not a member of ''CMsgDlg'' c:\program files\microsoft visual studio\myprojects\dialogs\msgdlg.h(13) : see declaration of ''CMsgDlg'' Error executing cl.exe. This is Day 5 on that book. Titled: "Getting User Feedback--Adding Dialog Boxes to Your Application". I am newbie so I just tried this book, but it gives me a lot of headache. Thanks for the help in advance

msdn.microsoft.com for the compiler codes, or install msdn locally.

The error speaks for itself, m_iOption isn''t declared in the header file (probably DialogsDlg.h), or the class it inherits from (if any). C++ is case sensitive, so it has to be dead right.

I would either skip ahead to the debug appendix (if the book has one), or re-read the chapters before, because you''ll going to be coming against that sort of thing often.

I just figured it out. m_iOption is a member of CMsgDlg, but! In my Class View. There TWO CMsgDlg. DialogsDlg is calling the clone which has no declaration, so, How Can I delete it? Or should I also put a declaration to the clone?
