设有如下通用过程:Public Function Fun(xStr As String) Dim tStr As String, srtL As
设有如下通用过程:
Public Function Fun(xStr As String)
Dim tStr As String, srtL As Integer
tStr+" "
strL=Len(xStr)
i=1
Do While i <=strL/2
tStr=tStr &Mid(xStr,i ,1)& Mid (xStr ,strL-i+1,1)
i=i+1
Loop
Fun=tStr
End Function
在窗体上画一个名称为 Textl 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 Command 1_ Click()
Dim S1 As String
S1="abcdef"
Text1.Text=UCase(Fun(S1))
End Sub
程序运行后,单击命令按钮,则Text1中显示的是()。 A.ABCDEF
B.abcdef
C.AFBECD
D.DEFABC
