被光標的位置，折騰了大半天.
問題，在程序中客戶區設置光標變為放大(Zoom out)光標.當放大光標(Zoom out)從客戶區接近到Scrollview 的ScrollBar時,應該變成普通的Arrow 光標.但奇怪的是，非但沒變，反而是越過Scrollbar ,才變成普通的Arrow 光標.
查看代碼中的OnSetCursor,SetCurosr 都不是問題，MSDN,Goole 一圈也沒發現，有人遇到此問題.
分析下,以為是光標大小問題,使用VC調整 Cursor資源,意外發現hot spot這個屬性,將放大光標（Zoom out）的hot spot從(0,0)調整到最下面的點(28,28)位置,運行程序,正常
MSDN 上的介紹,
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.
