VB的Picture1_MouseDown事件为什么连续点机鼠标左键 两次才执行操作一次?谢谢
Dim x1, y1, r As SinglePrivate Sub Form_Load()
x1 = 5000
y1 = 5000
r = 100
Picture1.Circle (x1, y1), r
End Sub
Private Sub Picture1_MouseDown(Button As Integer, Shift As Integer, X As Single, Y As Single)
r = r + 50
Picture1.Circle (x1, y1), r
End Sub
