Hi,
I working on the MDI Application.In ProfUIS When I have Child frames it looks like Tab window in the MainFrame. I have to Call a "Function()" Whenever I change the ChildFrame either by Clicking with Mouse on the Name of the ChildFrame or by Key Board operation (Ctrl+Tab).How to do it.
I have already used OnMDIActivate((BOOL bActivate, CWnd* pActivateWnd, CWnd* pDeactivateWnd); and ActiveFrame(int nCmdShow) Both r not working .
Thank u.

In OnMDIActivate I have give a MessageBox.This works fine in VC++6.0.But in Visual Studio 2005 (MFC) When I Click the Child View or Change the Tab (Ctrl+Tab)I don’t the get the MessageBox.I don’ Know What is the problem.As I told u before When I change the Tab using the Mouse Click or Ctrl+tab I have to Call a Function.
Thank u.Below is the Code.
void CChildFrame::OnMDIActivate(BOOL bActivate, CWnd* pActivateWnd, CWnd* pDeactivateWnd) { AfxMessageBox(_T("test")); CMDIChildWnd::OnMDIActivate(bActivate, pActivateWnd, pDeactivateWnd); // TODO: Add your message handler code here }

Here it’s not a good idea to test with MessageBox, as showing the messagebox will deactivate the frame and thus causing another OnMDIActivate call. For testing purposes you should call TRACE0("Test\n"); here, instead of MessageBox. This way, if OnMDIActivate is called, you will see your "Test" text in VS’s output window. Unfortunately I don’t know why VC++6.0 worked, but VS2005 doesn’t. Have you tried CView::OnActivateView?

Check out MSDN on CView::OnActivateView. It is definitely called when changing tabs, but unfortunately it is called many other times as well. Read MSDN for more information about this.
