在下面的代码,我得到一个编译时错误:Visual Basic 6.0中通过引用的问题传递
ByRef Argument type mismatch.
但是,如果我改变我的声明,J到:
Dim i As Integer
Dim j As Integer
错误消失了。为什么?
Private Sub Command2_Click()
Dim i, j As Integer
i = 5
j = 7
Call Swap(i, j)
End Sub
Public Sub Swap(ByRef X As Integer, ByRef Y As Integer)
Dim tmp As Integer
tmp = X
X = Y
Y = tmp
End Sub
