screen.mousepointer=vbdefault '默认
比如是Command1过程
Private Sub Command1_Click()
Command1.enable=false
Screen.MousePointer = vbHourglass'漏斗状
.........
Screen.MousePointer = vbDefault'恢复
Command1.enable=ture
End Sub
Label1.MousePointer = 11: Label2.MousePointer = 11: Label3.MousePointer = 11
..........
程序运行结束时再改回来
............
Label1.MousePointer = 0: Label2.MousePointer = 0: Label3.MousePointer = 0
(11这漏斗状,0为默认)
