class CMyView
{

    ..........
public:
    static CMyView* GetView();
    .........
};

对单视图的实现

CMyView* CMyView::GetView()
{
    CFrameWnd* pFrame = (CFrame*)(AfxGetApp()->m_pMainWnd);
    CView* pView = pFrame->GetActiveView();
    if(!pView)
        return NULL;
    if(!pView->IsKindOf(RUNTIME_CLASS(CMyView)))        
        return NULL;
    return (CMyView*)pView;
        
}

对多文档的实现

CMyView* CMyView::GetView()
{
    CMDIChildWnd* pChild = 
        ((CMDIFrameWnd*)(AfxGetApp()->m_pMainWnd))->MDIGetActiveView();
    if(!pView)
        return NULL;
    if(!pView->IsKindOf(RUNTIME_CLASS(CMyView)))
        return NULL;
    return (CMyView*)pView;
}

同样，对单视图，还可以用如下的方法：
#include "MyDoc.h"
#include "MyView.h"
extern CMyView* pView;

在MyView.cpp中
CMyView* pView;

CMyView::CMyview()
{
    pView = this;
}
