被光标的位置，折腾了大半天.
问题，在程序中客户区设置光标变为放大(Zoom out)光标.当放大光标(Zoom out)从客户区接近到Scrollview 的ScrollBar时,应该变成普通的Arrow 光标.但奇怪的是，非但没变，反而是越过Scrollbar ,才变成普通的Arrow 光标.
查看代码中的OnSetCursor,SetCurosr 都不是问题，MSDN,Goole 一圈也没发现，有人遇到此问题.
分析下,以为是光标大小问题,使用VC调整 Cursor资源,意外发现hot spot这个属性,将放大光标（Zoom out）的hot spot从(0,0)调整到最下面的点(28,28)位置,运行程序,正常
MSDN 上的介绍,
Setting a
Cursor's Hot Spot
The hot
spot of a cursor
is the point to which Windows refers in tracking the cursor's position.
By default, the hot spot is set to the upper-left corner of the cursor
(coordinates 0,0). The Hotspot property in the Properties
window shows the hot spot coordinates.
To set a cursor's hot spot
-
On the Image
Editor toolbar, click the Set Hotspot tool.
-
Click
the pixel you want to designate as the cursor's hot spot.
The Hotspot
property in the Properties window displays the new coordinates.
