OK, maybe not as easily, but it's certainly doable. - Jamie Nordmeyer - 15-Nov-2002

CMainFrame * pMain = (CMainFrame*) AfxGetMainWnd(); pMain->GetActiveView(); Sorry, I abandoned MFC a long time ago.

It's ok thanks for trying :) in my program the is no GetActiveView() i keep getting an error. maybe i'm putting this in the wrong way this is what i have CTestView * pView= (CTestView*)AfxGetMainWnd(); and lets say i want to call and function or an object like this pView->m_cThumbFrame.Add("picture.bmp"); but this dosen't work :(:((:((:((

E3 wrote: in my program the is no GetActiveView() i keep getting an error. After the cast ? Compiles fine here. E3 wrote: CTestView * pView= (CTestView*)AfxGetMainWnd(); Won't work. You'll get the CMainFrame class, which when cast has a GetActiveView() method.

If not you are to crush and not to know why.:~ (If you do´t do this than check with the CObject::IsKindOf or something that the pointer is a object type of the class) Try this @ home. (B&B)

This guarantees that I'm working on the correct view. Assuming you are calling your function from your CFrameWnd derived class, you may be able to use GetActiveView and cast it to the CTestView. I prefer the first method but then I tend to have a lot of CView classes in my projects. Michael Fat bottomed girls You make the rockin' world go round -- Queen
