这个代码我也试了,设置setcapture()后对话框的4个方面的鼠标进出判断很准确,但如果没有setcapture()只有右侧是准确的,不知道是怎么回事?

鼠标移到当前窗体的控件上也作为移出窗体外而相应消息了
-------------------------------------------------------
这个没办法,只有在OnMouseLeave的时候检查一下鼠标的位置,然后计算是否在窗口内,然后再做你需要的相应处理

我看了我看，大体上对了，不多有个问题就是：鼠标移到当前窗体的控件上也作为移出窗体外而相应消息了，该怎么弄呀？

WM_MOUSELEAVE Notification
--------------------------------------------------------------------------------
The WM_MOUSELEAVE message is posted to a window when the cursor leaves the client area of the window specified in a prior call to TrackMouseEvent.
A window receives this message through its WindowProc function.
Syntax
WM_MOUSELEAVE
WPARAM wParam
LPARAM lParam;
Parameters
wParam
Not used; must be zero.
lParam
Not used; must be zero.
Return Value
If an application processes this message, it should return zero.
Remarks
All tracking requested by TrackMouseEvent is canceled when this message is generated. The application must call TrackMouseEvent when the mouse reenters its window if it requires further tracking of mouse hover behavior.

消息处理，还有一个办法圈一个区域也就是窗口句柄，判断一下鼠标坐标是正值还是负值，就可以了

看看是否执行了_TrackMouseEvent(&tme);这个函数

修改:
ON_MESSAGE(WM_MOUSEHOVER, OnMouseHover) //把这行去掉
ON_MESSAGE(WM_MOUSEHOVER, OnMouseHover) //把这行去掉

定义一个成员:
BOOL bTracking;
afx_msg LRESULT OnMouseLeave(WPARAM wParam, LPARAM lParam);
初始化成员:
bTracking = FALSE;
消息映射:
ON_MESSAGE(WM_MOUSELEAVE, OnMouseLeave)
ON_MESSAGE(WM_MOUSEHOVER, OnMouseHover)
Mouse移动事件中写:
void CXXXDlg::OnMouseMove(UINT nFlags, CPoint point)
{
if( !m_bTracking )
{
TRACKMOUSEEVENT tme;
tme.cbSize = sizeof(tme);
tme.hwndTrack = m_hWnd;
tme.dwFlags = TME_LEAVE;
tme.dwHoverTime = 0;
m_bTracking = _TrackMouseEvent(&tme);
}
CDialog::OnMouseMove(nFlags, point);
}
Mouse离开事件中写:
LRESULT CXXXDlg::OnMouseLeave(WPARAM wParam, LPARAM lParam)
{
m_bTracking = FALSE;
// 在这里处理Mouse离开事件
// ...
return 0;
}
BOOL bTracking;
afx_msg LRESULT OnMouseLeave(WPARAM wParam, LPARAM lParam);

ON_MESSAGE(WM_MOUSEHOVER, OnMouseHover)
