如何用VB.NET写一个简单的屏幕保护程序？
在窗体上建立2个文本框text1和text2，一个按钮command1，text1里面输入你要转换的字符串，text2里面显示结果，代码如下：

Dim MyString As String
Dim EveryStr(50) As String
Dim TargetStr As String
Private Sub Command1_Click()
MyString = Text1
For i = 1 To Len(MyString)
EveryStr(i) = Right(Left(MyString, i), 1)
If Asc(EveryStr(i)) 123 And Asc(EveryStr(i)) 96 Then EveryStr(i) = \"_\"
If Asc(EveryStr(i)) 91 And Asc(EveryStr(i)) 64 Then EveryStr(i) = \"_\"
TargetStr = TargetStr EveryStr(i)
Next i
Text2 = TargetStr
TargetStr = \"\"
End Sub
引号前面怎么自动给加了个“\”？用的时候请手动把那几个“\”去掉
求VB屏保的代码....要简单的 进入(黑色)屏保後，例如只要按一下ESC就可以回到正常这样就可以了,,,,邮箱
