打开资源，右击添加->选择Cursor->IDC_POINTER

头文件添加

public:

HCURSOR CUR;

protected:

void LoadCursorID(UINT Cur);

UINT CurName;

void CapPoint(CPoint MousePos);

源文件中添加

{

CRect r;

GetClientRect(&r);

switch(Width)

case 2:

}

CUR=AfxGetApp()->LoadCursor(CurName);

Invalidate();

}

void Cvc1001View::OnMouseMove(UINT nFlags, CPoint point)

{

// TODO: 在此添加消息处理程序代码和/或调用默认值

CapPoint(point);

::SetCursor(CUR);

Invalidate();//刷新窗口
