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

Private Declare Function SetWindowPos Lib "user32" (ByVal hwnd As Long, ByVal hWndInsertAfter As Long, ByVal X As Long, ByVal Y As Long, ByVal cx As Long, ByVal cy As Long, ByVal wFlags As Long) As Long

Private Const HWND_TOPMOST = -1

Private Const HWND_TOP = 0

Private Const WM_SHOWWINDOW = H18

Private Sub Form_KeyPress(KeyAscii As Integer)

If KeyAscii = 27 Then

Unload Me

End If

End Sub

Private Sub Form_Load()

'在属性窗口中将Form1的BorderStyle设为None

Me.BackColor = vbBlack

SetWindowPos Me.hwnd, HWND_TOPMOST, 0, 0, Screen.Width, Screen.Height, WM_SHOWWINDOW

End Sub

'如果要设为屏保，需将生成的exe文件后缀改为scr，保存到system32中，并在电脑中选择此屏保
