程序效果：
当点击左边的部件图时，会弹出对话框提示你点击了哪一个区域。
程序思路：
用一个图片区域码图作为点击区域的参照，根据XY取得的颜色识别出属于哪一个区域
程序界面如下：
相关代码如下：
Visual Basic Code
Dim ColorArray ( ) As Long
Dim ColorCount As Long
Private Sub Form_Load ( )
'初始化颜色数量
ColorCount = Picture3.Width / 10
ReDim ColorArray ( 1 To ColorCount )
For X = 1 To ColorCount
ColorArray ( X ) = Picture3.Point ( ( X * 10 ) - 5, 5 )
Next X
End Sub
Private Sub Picture1_MouseDown ( Button As Integer, Shift As Integer, X As Single, Y As Single )
If Button = 1 Then
Dim NowColor As Long
NowColor = Picture2.Point ( X, Y )
If NowColor <> RGB ( 255, 255, 255 ) Then
Dim i As Long
For i = 1 To ColorCount
If NowColor = ColorArray ( i ) Then
ButtonClick i
Exit For
End If
Next i
End If
End If
End Sub
Private Sub ButtonClick ( Index As Long ) &n
