We're embedding the spread control in an MFC view; we have found that when the user re-activates the spread-view, the embedded control will not take focus.  That is, when the view is re-activated, the control does not take focus, even when specifically asked to.

We are overriding CView::OnActivateView like so:

void CSheetView::OnActivateView(BOOL bActivate, CView* pActivateView, CView* pDeactiveView)
{
    CInfoView::OnActivateView(bActivate, pActivateView, pDeactiveView);

    if ( bActivate )
    {
        m_SSWnd.SetFocus();
    }
}

Any idea what we're doing wrong?

Hello,

It sounds like when you have an ActiveX control in a CView, like this, calling the Focus methos is not activating the ActiveX control. You would probably see the same problem with any ActiveX control you use. I would suggest contacting the Microsoft group for a function call you can make to activate an ActiveX control.

We are migrating from the use of Formula 1's ActiveX spreadsheet control to the FarPoint Spread ActiveX control.  We embed the Formula 1 control in a CView and use SetFocus on the control to give it focus when the view is activated, just like in my example code.  And it works.  So I don't think that it is a general ActiveX control problem - it is something specific to the FarPoint Spread control.

If you could provide a sample program that embeds your control in a CView, and properly assigns keyboard focus to the control when the user Alt-Tabs back to the program, that would be much appreciated as it would help us find what the problem is...

Thanks

I think I figured out the problem.  It seems that calling the CWnd::SetFocus method on the FarPoint Spread control's wrapper  doesn't work, but calling ::SetFocus( controlWnd.GetSafeHwnd() ) does!  (Any idea why?)

After figuring that out, I also found that overriding the CView's OnSetFocus handler is neccessary for some situations as well:

CMyView::OnSetFocus( CWnd * p )
{
    CParentView::OnSetFocus( p );
    ::SetFocus( m_pFarPointSpreadWnd->GetSafeHwnd() );
}

Thanks
