Automatically arrange visible controls below the tab control

Here is some code for realigning the controls present on a property sheet. The code realigns the controls that are beneath the tab control, which have the WS_VISIBLE style. The controls are repositioned from right to left, in reverse tab order, and being separated by a standard distance. This is handy for realigning the controls after you have changed the visibile state of the buttons at the bottom of the property sheet. You can also use this function during OnInitDialog(..) as the visible state of the controls is obtained by checking the window style of the child control, and not by using IsWindowVisible(..).

void CPropertySheetDerivedClass::AutoArrangeButtons() 
{
	CWnd* pWnd = GetDlgItem(ID_APPLY_NOW);
	
	if (pWnd && ::IsWindow(pWnd->m_hWnd))
	{
		// Get the last control in the tab order - (tab order is the same as creation order)
		pWnd = pWnd->GetWindow(GW_HWNDLAST);

		// Get the tab control
		CTabCtrl* pTabCtrl = GetTabControl();

		// Get the child identifier of the tab control
		int nTabControlID = ::GetWindowLong(pTabCtrl->m_hWnd, GWL_ID);

		// Child control identifier
		int nControlID = 0;

		// The window rect of the tab control.
		CRect rcTAB(0, 0, 0, 0);

		pTabCtrl->GetWindowRect(rcTAB);

		ScreenToClient(rcTAB);

		CRect rcTemp(0, 0, 0, 0);

		GetClientRect(rcTemp);

		int nLeft = rcTemp.right;
		int nSpacing = rcTemp.right - rcTAB.right;

		// do this bit while we have a control to do something with
		while(pWnd)
		{
			// Get the ID of the current child control
			nControlID = ::GetWindowLong(pWnd->m_hWnd, GWL_ID);
			
			// Do not make changes to the tab control!!
			if (nControlID != nTabControlID)
			{
				// do some stuff
				pWnd->GetWindowRect(rcTemp);

				ScreenToClient(rcTemp);

				// Is the child control visible? - Don't use IsWindowVisible as the parent
				// also has to be visible for that to return TRUE;
				BOOL bChildIsVisible = ((pWnd->GetStyle() & WS_VISIBLE) == WS_VISIBLE);

				// Make sure we are below the TAB control
				if ((rcTemp.top > rcTAB.bottom) && bChildIsVisible)
				{
					// Move each control
					nLeft -= nSpacing + rcTemp.Width();
					
					pWnd->MoveWindow(nLeft, rcTemp.top, rcTemp.Width(), rcTemp.Height());
				}
			}
				
			// Go back in the TAB order again
			pWnd = pWnd->GetWindow(GW_HWNDPREV);
		}
	}
}
