Tab stops no longer work

I switched from a CFormView to a CScrollView as a base class for my view in an SDI app. The switch helped me with some things, but it caused the tab stops for my controls (edits) to no longer work. Can someone tell me a way to get the tab stops back? (I'm using Visual C++ 6 SP5)

Hi!
You need to override PreTranslateMessage in the your view view:

BOOL CMyView::PreTranslateMessage(MSG* pMsg)
{
      ASSERT(pMsg != NULL);
      ASSERT_VALID(this);
      ASSERT(m_hWnd != NULL);

      // allow tooltip messages to be filtered
      if (CScrollView::PreTranslateMessage(pMsg))
            return TRUE;

      // don't translate dialog messages when in Shift+F1 help mode
      CFrameWnd* pFrameWnd = GetTopLevelFrame();
      if (pFrameWnd != NULL && pFrameWnd->m_bHelpMode)
            return FALSE;

      // since 'IsDialogMessage' will eat frame window accelerators,
      //   we call all frame windows' PreTranslateMessage first
      pFrameWnd = GetParentFrame();   // start with first parent frame
      while (pFrameWnd != NULL)
      {
            // allow owner & frames to translate before IsDialogMessage does
            if (pFrameWnd->PreTranslateMessage(pMsg))
                  return TRUE;

            // try parent frames until there are no parent frames
            pFrameWnd = pFrameWnd->GetParentFrame();
      }

      // don't call IsDialogMessage if form is empty
      if (::GetWindow(m_hWnd, GW_CHILD) == NULL)
            return FALSE;

      // filter both messages to dialog and from children
      return PreTranslateInput(pMsg);
}

The code looks great, but the tab doesn't wrap around back to the beginning. How can I get it to wrap around?

Actually, I think the tabs are getting stuck on a rich edit control instead of not wrapping around.

The code works for normal edit controls but not for rich edit controls. Can an expert help me tab rich edit controls?

Do you really want to stop the user putting a tab into a RichEdit (stop part of formatting)?  

Override PreTranslateMessage in your view.
BOOL CMyView::PreTranslateMessage(MSG* pMsg)
{
    if(pMsg->message == WM_KEYDOWN)
      {
            long nID = ::GetDlgCtrlID(pMsg->hwnd);
            if((pMsg->wParam == VK_TAB) && (nID == IDC_MY_RICH_EDIT))

now put in the behaviour you want eg. NextDlgCtrl() then return TRUE to show the system you have handled the message

Also you must handle SHIFT+TAB keystroke to move focus to the previous control.
