I am using VC40 on WinNT 3.51 with NewShell installed.

I have an application that has several documents defined.
Depending on some user action I want to set which document should be active.

Has anyone come up with a solution for this ?

I tried this code which I thought would work, but it doesn't.

void CMyDoc::BringToTop()
{
   POSITION pos;
   pos = GetFirstViewPosition();
   // this function should not be called if pos == NULL
   ASSERT(pos);
   GetMainWnd()->SetActiveView(GetNextView(pos));
}

Stepping through SetActiveView shows that it will try to change the view
within the document object only. It seems like CFrameWnd::SetActiveView only
works within the document.

Anoyone got another idea.

Mats,

It is possible to iterate through the document template list and then
through the documents in each template. I can't quote code at the moment
because I don't have any handy, but I have used this method before, similar
to the document iteration using the POSITION value.

Cheers,
Simon.

Our MDI app uses this code to change the active view on
the screen (This code is in the middle of a member function
of the view that *should* be active)

        CMDIChildWnd* pThisChild = (CMDIChildWnd*)GetParentFrame();
        ASSERT_VALID(pThisChild);
        pMainFrame->MDIActivate(pThisChild);
        pThisChild->SetActiveView(this);
