追答

Private Sub Command1_Click()
Dim i As Integer, str As String, txt1len As Integer
str = ""
txt1len = Len(Text1.Text)
txt2len = Len(Text2.Text)
ReDim txt1(txt1len) As String
ReDim txt2(txt2len) As String
For i = 1 To max(txt1len, txt2len)
If i len2 Then
max = len1
Else
max = len2
End If

End Function
