Changing Focus on Press Tab

In Plain Win32 I have worked with this issue. in fact its very simple. I wrote the message loop like below:

while(GetMessage(&msg,0,0,0))
    {
        if (!IsDialogMessage(ghwnd, &msg) && !IsDialogMessage(hViewWindow, &msg) && !TranslateAccelerator( msg.hwnd,haccel ,&msg))
        {
            TranslateMessage(&msg);
            DispatchMessage(&msg);
        }
    }

none of the HWND in IsDialogMessage is dialog box.

Anyway. What can be done in mfc?

I think, I can over ride the

CWinApp::Run

Function and do the same thing like above...

But I dont like it as a solution. What would happen if I need more than 1000 handler(just saying).

in that case it can be a solution

ArrayOfRunningHwnd.Number[0]=Hwnd1;
ArrayOfRunningHwnd.Number[1]=Hwnd2;
ArrayOfRunningHwnd.Number[2]=Hwnd2;
ArrayOfRunningHwndcount=2;
bool processAllWindowForTab(ArrayOfRunningHwnd)
{
 for(int i=0;i<arrayofrunninghwndcount;i++)>
 {
  if(IsDialogMessage(ghwnd, &msg)==true)
   return true;
 }
 return false;
}

But In case of mfc(I am not good at C++) all sub window is derived from various Class. Is it possible to do something like above for those various class.

Here is an example what I am thinking..

ArrayOfRunningHwnd.Number[0]=m_pclassC; //class C:public CWnd;
 ArrayOfRunningHwnd.Number[1]=m_pclassA; //class A:public CWnd;
 ArrayOfRunningHwnd.Number[2]=m_pclassB;//class B:public CWnd;
 ArrayOfRunningHwndcount=2;
 bool processAllWindowForTab(ArrayOfRunningHwnd)
 {
  for(int i=0;i<ArrayOfRunningHwndcount;i++)
  {
   if(IsDialogMessage(ghwnd, &msg)==true)
    return true;
  }
  return false;
 }

Will it work(You might think why i am asking. I can do and test it it does).

The reason I am asking is to know whether there is a better solution for this.
