设计VB程序,该程序将输入的字符串中小写字母转换成大写字母后输出。在文本框Text1中输入一串字符(数字、字母均可),单击“转换”按钮Command1,在标签Label2中输出结果。(提示:Asc(x):将字符x转换为ASCII码值;Chr(x):将ASCII代码x转换为所对应的字符)该程序的设计界面如图所示,请根据算法将下列程序补充完整。
Private Sub Command1_Click()
Dim ch As String, s As String
Dim i As Integer, j As Integer
ch = Text1.Text
For i =" 1" To (1)
j =" Asc(Mid(ch," i, 1))
If j > 96 And j < 123 Then
s =" s" + Chr(j - 32)
Else
s =" s" + Chr(j)
End If
Next
(2)
End Sub
