关于BYVAL类型不匹配的问题!

dim porti as long
Private Sub EDSock_SwitchChange(ByVal ConnectID As Long, ByVal PortNum As Long, ByVal Value As Long)
'For PortNum = 1 To 16
PortNum = Porti + 1

'输入端口短路
If Value = 1 And iPhotoIndex(PortNum - 1) = Value Then

' 加载红灯显示状态
picinput(PortNum - 1).Picture = LoadPicture("C:\David 's bag\Item\R.bmp")
iPhotoIndex(PortNum - 1) = Value - 1

ElseIf Value = 0 And iPhotoIndex(PortNum - 1) = Value Then
'断路状态
picinput(PortNum - 1).Picture = LoadPicture("C:\David 's bag\Item\Z.bmp")
iPhotoIndex(PortNum - 1) = Value + 1

End If
'Next PortNum

End Sub

运行时提示说类型错误.怎么回事?

// picinput(PortNum - 1).Picture = LoadPicture("C:\David 's bag\Item\R.bmp")

类似这样的代码，前面要加个set，即：
set picinput(PortNum - 1).Picture = LoadPicture("C:\David 's bag\Item\R.bmp")

要把dim porti as long放到过程里去才行
你没把他放到过程中肯定报错,因为没声明
