SDI中pDoc获得pView方法

以前一直通过pMainWnd中转 其实可以写个函数调用 

.h

CView* GetView(CRuntimeClass* pClass);

.cpp

CView* CxxxDoc::GetView(CRuntimeClass* pClass)
{
	CView* pView;
	POSITION pos = GetFirstViewPosition();

	while(pos != NULL)
	{
		pView = GetNextView(pos);
		if(!pView->IsKindOf(pClass))
		{
			break;
		}
	}

	if(!pView->IsKindOf(pClass))
	{
		AfxMessageBox(_T("View Pointer Error"));
		return NULL;
	}

	return pView;
}

调用的时候记得这样

CxxxView *pView= (CxxxView *)GetView(RUNTIME_CLASS(CxxxView));
