winapi - Add Controls To Specific Tab Page in TabControl in C++ Win32

Question

I want to add some controls to the tab page in tabcontrol but it seems that it will be added to all pages and there is not tab page in tabcontrol by default.

I have read these links below but they did not help me and in some parts of them, confused me.

Here is my code :

HWND hWnd;

void InserTabItem(HWND handle, LPWSTR text, int id)
{
TCITEM tci = { 0 };
tci.mask = TCIF_TEXT;
tci.pszText = text;
tci.cchTextMax = wcslen(text);
SendMessage(handle, TCM_INSERTITEM, id, LPARAM(&tci));
}

LRESULT CALLBACK WndProc(HWND hWnd, UINT Msg, WPARAM wParam, LPARAM lParam)

}

ShowWindow(hWnd, ncmdshow);
UpdateWindow(hWnd);



MSG wnd_msg;
while (GetMessage(&wnd_msg, NULL, 0, 0)>0)
{
    TranslateMessage(&wnd_msg);
    DispatchMessage(&wnd_msg);
}
return (int)wnd_msg.wParam;

}

I am looking for a safe and proper implementation.

Thanks for any help

[Update]:

Thanks for comments but no answer in detail :(

Although that is not the implementation I am looking for(NotDialogBased), But from the forth link I mentioned :

One problem is here:

pHdr->hwndDisplay = CreateDialogIndirect(hInstance_Win_Global, 
    (DLGTEMPLATE*)pHdr->apRes[iSel], hwndDlg, DialogProc);

You are reusing the same dialog procedure for both main dialog and child dialogs. Main dialog creates child dialogs, child dialogs use the same procedure to create child dialogs... Also there are no error checks.

Beyond that, this code is too complicated. Just use a dialog box for main window. Create a new dialog IDD_DIALOG1 and drag/drop a tab control in it. Assign IDC_TAB1 for tab control ID. Try starting with this code instead:

#include <Windows.h>
#include <CommCtrl.h>
#include "Resource.h"

#pragma comment(lib,"comctl32.lib")
#pragma comment(linker,""/manifestdependency:type='win32' name='Microsoft.Windows.Common-Controls' version='6.0.0.0' processorArchitecture='*' publicKeyToken='6595b64144ccf1df' language='*'"")

    case WM_COMMAND:
        switch (wp) {

        }
    }
    return FALSE;
}

void OnSelChange() {
    int sel = TabCtrl_GetCurSel(data.tab);
    ShowWindow(data.page1, (sel == 0) ? SW_SHOW : SW_HIDE);
    ShowWindow(data.page2, (sel == 1) ? SW_SHOW : SW_HIDE);
}
