Ok the best method is to handle this in the WM_WINDOWPOSCHANGED message as this happens just after the window has appeared

It works perfect now, cheers

Found a better implementation, is to start a timer, then in the timer function to have

IsWindowVisble()

and if not then exit timers

Also playing with WM_WINDOWPOSCHANGED

Cheers

Sorry, i make a mistake:

...
- I define a member BOOL m_bFirstActivation, initialized with TRUE
...
case WA_ACTIVE:
   if( m_bFirstActivation == TRUE )
   {
	OnFirstActivation();
	m_bFirstActivation = FALSE; 
   } 
   break;

 that is

Hi,
I use a workaround for this:
    - I define a member BOOL m_bFirstActivation, initialized with FALSE
    - catch the message WM_ACIVATE - ON_WM_ACTIVATE()
    - toggle m_bFirstActivation in the message method, do the first initialization

void CMainFrame::OnActivate(UINT nState, CWnd* pWndOther, BOOL bMinimized) 
{
	CFrameWnd::OnActivate(nState, pWndOther, bMinimized);
	
	// TODO: Add your message handler code here
	switch( nState )
	{
	case WA_CLICKACTIVE:	case WA_ACTIVE:
		if( m_bFirstActivation == FALSE )
		{
		   	OnFirstActivation();
			m_bFirstActivation = FALSE; 
		} 
		break;
	case WA_INACTIVE:
		break;
	}	
}

Hope that it will help you. There is may be a better way ...

Anybody know what function is called after OnShowWindow() in MFC ???

As I need to make sure a window is shown before showing a dialog, currently have in a timer, but this sometimes fails.

Any help much appreciated
