تغيير در رجيستري ويندوز

ميخواهم يك مقدار رشته اي را در يك ورودي موجود در رجيستري بنويسم ولي آنچه در اثر كد زير نوشته ميشود با چيزي كه من تايپ ميكنم فرق دارد؟ راهنمايي كنيد

Option Explicit
Dim KeyName As String
Dim EntryName As String
Dim Subtree As Long

Private Sub Form_Load()
Subtree = HKEY_LOCAL_MACHINE
"KeyName = "SYSTEM\Setup
"EntryName = "CmdLine
End Sub

Private Sub ReadBtn_Click()
Dim hKey As Long
Dim lRetVal As Long
Dim vValue As Variant
Dim lValue As Long
(lRetVal = RegOpenKeyEx(Subtree, KeyName, 0, KEY_QUERY_VALUE, hKey
(lRetVal = QueryValueEx(hKey, EntryName, vValue
Me.ValueBox.Text = vValue
End Sub

()Private Sub WriteBtn2_Click
Dim lRetVal As Long
Dim hKey As Long
Dim EntryType As Long
Dim sValue As String
sValue = Me.ValueBox.Text
EntryType = REG_SZ
(lRetVal = RegOpenKeyEx(Subtree, KeyName, 0, KEY_ALL_ACCESS, hKey
(lRetVal = SetValueEx(hKey, EntryName, EntryType, sValue
( RegCloseKey (hKey
End Sub

سلام دوست عزیز.
اگه مشکلتون حل نشده بگید تا یه ماژول برای کار با رجیستری براتون بزارم که کار باهاش خیلی راحته.

منظورت واضح نيست
چي رو تايپ مي كني؟
