Hello, the codegurus around the world.;) I often use this function from "HOW-TO VISUAL C++ 4.0" by Scott ? to change the active view on MDI application. void CMainFrame::SwitchToView(CDocTemplate* pTemplate, CRuntimeClass* pViewClass) { CMDIChildWnd* pMDIActive = MDIGetActive(); CDocument* pDoc = pMDIActive->GetActiveDocument(); CView* pView; POSITION pos = pDoc->GetFirstViewPosition(); while(pos != NULL) { pView = pDoc->GetNextView(pos); if(pView->IsKindOf(pViewClass)) { //the requested view has already been created; show it pView->GetParentFrame()->ActivateFrame(); return; } } //The requested view hasn't been created yet CMDIChildWnd\* pNewFrame = (CMDIChildWnd\*) pTemplate->CreateNewFrame(pDoc, NULL); if(pNewFrame == NULL) return; pTemplate->InitialUpdateFrame(pNewFrame, pDoc); } and call this function anywhere like this. ((CMainFrame\*)AfxGetMainWnd())->SwitchToView(theApp.m\_pAppTemplate, RUNTIME\_CLASS(CAppView)); Have a nice day! -Masaaki Onishi-

By using SetCapture in LMBDown you can make your window continue to recieve the events when your mouse leaves the window. You can also use OnMOuseMove to check your position and limit it ( you'll still need setcapture to get the message ) but limiting a users mouse movement is almost never a good idea. Don't forget to call REleaseCapture in LMB up. Use a ScrollView and you get the scrollers for free A scrollview will probably fix problem 3 as well.

handle the OnUpdate() message and set the scroll sizes there depending on the 'size' of your doc and the font size you are using --- "every year we invent better idiot proof systems and every year they invent better idiots"

Thanks for your help but, I did overwrite OnSize() setting cx and cy to what i want but it was ignored, i used it before and after the default call, i don't know what to do with WM_GETMINMAXINFO, i can't see it in classwizard, need more detail... Thanks F.Dost

Check the docs for WM_GETMINMAXINFO message: "The WM_GETMINMAXINFO message is sent to a window when the size or position of the window is about to change. An application can use this message to override the window's default maximized size and position, or its default minimum or maximum tracking size." Tomasz Sowinski http://www.shooltz.com.pl
