设有如下通用过程:
Public Function Fun(xStr As String) As String
Dim sStr As String, strL As Integer
tStr=""
strL=Len(xStr)
i=strL/2
Do While i<=strL
tStr=tStr & Mid(xStr, i+1, 1)
i=i+1
Loop
Fun=tStr & tStr
End Function
在窗体上画一个名称为Text1的文本框和一个名称为Command1的命令按钮。然后编写如下的事件过程:
Private Sub Command1_Click()
Dim s1 As String
s1="ABCDEF"
Text1.Text=Lease(Fun(s1))
End Sub
程序运行后,单击命令按钮,文本框中显示的是
A.ABCDEF
B.abcdef
C.defdef
D.defabc
