Hi,

Try:

POSITION Pos = GetFirstDocTemplatePosition();
CDocTemplate * pTem = GetNextDocTemplate(Pos);

POSITION DocPos = pTem->GetFirstDocPosition();
CDocument * pDoc = GetNextDoc(DocPos);

POSITION ViewPos = pDoc->GetFirstViewPosition();

while(ViewPos != NULL)
{
CView * pView = GetNextView(ViewPos);
pView->SomeFunction();
}

hi group,

i am programming a mdi application.
in which i want the active view's pointer.
so after searching i got this code on msdn.

void CMainFrame::StepLine(CString Line)
{

//pView->HighLightLine(Line);

CMDIFrameWnd *pFrame =
(CMDIFrameWnd*)AfxGetApp()->m_pMainWnd;

if(pFrame)
{
CMDIChildWnd *pChild =
(CMDIChildWnd *) pFrame->MDIGetActive();//here it gives
//assertion as given below

if(pChild)
{
CTritonSpiritBoardView *pView = (CTritonSpiritBoardView *)
pChild->GetActiveView();
}

}

}

Debug assertion failed!
Program:
File:winmdi.cpp
Line:341

why this api is failing??
if anybody know's please tell me
