I would like to add 3 DialogBoxes.
And later work with each DialogBoxes.
I think I have to work with new add a new class for each Tab.

Please be so kind to help me. I am a beginner in Visual C++....and need some credits.
Thank you. 500 Points

m_tabRegister is a variable from CTabCtrl


....OnInitDialog()
//####################################################
      TCITEM Register;
      Register.mask=TCIF_TEXT;
              //---- set single Register ------
      Register.pszText="Tab 1";
      m_tabRegister.InsertItem(0,&Register);

    Register.pszText="Tab 2";
      m_tabRegister.InsertItem(1,&Register);

    Register.pszText="Tab 3";
      m_tabRegister.InsertItem(2,&Register);
    //-----------------------------------------
      m_tabRegister.SetCurSel(0);// set first Register



//##################### Register #############################
void CTabControlDlg::OnTcnSelchangeRegister(NMHDR *pNMHDR, LRESULT *pResult)
{
      int nChoose = m_tabRegister.GetCurSel();
             
      switch(nChoose)
      {
      case 0:
            UpdateData(FALSE);
            break;
      case 1:
            UpdateData(FALSE);
            break;
      case 2:
            UpdateData(FALSE);
            break;
      }

      *pResult = 0;
}

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
}

What error exactly?

To change m_myTabCtrl type from CTabCtrl to CMyTabCtrl, you need to add line
#include "CMyTabCtrl.h"
to dialog h-file:

// TabControl_ClassDlg.h : Headerdatei
//

#pragma once
#include "afxcmn.h"

#include "RegisterKontrolle.h"
#include "CMyTabCtrl.h"

class CTabControl_ClassDlg : public CDialog
{
    ....

//     CTabCtrl m_myTabCtrl;
     CMyTabCtrl m_myTabCtrl;
};

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

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

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