分享急！急！ 数据窗中鼠标滚轮的问题?
I use mousescrolling event in my Win98/
PowerBuilder/ Datawindow ,and the mousescroll
does well when there is no groups in the
datewindow. However when i add groups to the datawindow, and then run my application,an "illegal operation" will occure and my application terminate.
How can i solve this problem?

由于鼠标滚轮滚动时触发WM_MOUSEWHEEL(代码522)消息，屏蔽它：
在数据窗控件的other事件中加一句
//如果触发WM_MOUSEWHEEL(代码522)消息，不继续处理
if message.number=522 then return 1
