How to create a TabControl 500 Points....please help

http://www.codeguru.com/cpp/controls/controls/tabcontrols/article.php/c5239/

Firstly add the CMyTabCtrl.cpp and CMyTabCtrl.h to your project.
?? add a new class to my TabControl??


what kind of member variable is this: m_tabPages and m_nNumberOfPages
Please let me know, thanks.

Download demo project and read it, I hope this can help better than my explanations. Download link is in the end of the article.
If you are new in CodeGuru and similar sites, this is the way to work with them - first try code, then read article, if code is working.

Specifically about your question. Using VC++ Class Wizard, you can add variable of type CTabCtrl to the dialog class. Then add line
#include "CMyTabCtrl.h"
to the dialog h-file, and manually change variable type from CTabCtrl to CMyTabCtrl.

Hi Alex,
yes the program works when I load the project into my Visual Studio C++

I have tried the code in a new project that I wrote.
I can not change     CTabCtrl m_myTabCtrl       to CMyTabCtrl
I will get an error when I start to compile my program.
How can I do this ?

Everything else would works.

Here is the problem:
Error: RegisterAuswahl()  same as Init() do not belong to CTabCtrl
...in Dlg.cpp
      SetIcon(m_hIcon, TRUE);
      SetIcon(m_hIcon, FALSE);      
      
      m_myTabCtrl.InsertItem(0, _T("Tab One"));
      m_myTabCtrl.InsertItem(1, _T("Tab Two"));
      m_myTabCtrl.InsertItem(2, _T("Tab Three"));

      m_myTabCtrl.RegisterAuswahl();        //RegisterAuswahl = Init()

      // TODO: Hier zusätzliche Initialisierung einfügen
      
      return TRUE;  // Geben Sie TRUE zurück, außer ein Steuerelement soll den Fokus erhalten
}

Hi Alex,
now it works. I changed the CMyTabCtrl into RegisterKontrolle.
I forgot to change  CMyTabCtrl m_myTabCtrl; into Registerkontrolle m_myTabCtrl.

The only (I hope simple)problem now=>
when I change the tabs on the tab register, the new dialogs are in th upper left side
of my screen of Visual C++ Net  and not in the tab control.
Please let me know. Thanks Alex.
Best regards,
Thomas

Hi Alex,
I just had to change some setting for each DialogBox IDD_DIALOG1-IDD_DIALOG3.
Now everything works just fine.
Thanks for your great help.
I have just added 500 points for you.
Have a great day.
Best regards,
Thomas

Does this happen in CodeGuru sample? CMyTabCtrl::SetRectangle function must do the work.

No the CodeGuru sample works just fine.
I just wanted to create a new project with the code for me.

You need to use CMyTabCtrl class directly in your project. Maybe you made some mistake copying the code.
