enable/disable proxy thru application

Hi,

I am able to enable the proxy and feed my provided IP address and port no for the proxy.This works fine but when i try to disable it and go to the tools->Internet Options->connections->LAN settings i dont see it disabled.
Even rebooting the machine didnt help.
The the probelem is that i am able to enable and feed the value but am not able to disable the proxy thru my application.
I am using VB 6.0.
Here is the code :

VB Code:

Private Const HKEY_CURRENT_USER = &H80000001
Private Const REG_SZ = 1
Private Const REG_SZ1 = 0
Private Const REG_BINARY = 3
Private Const REG_DWORD = 4
Private Const ERROR_SUCCESS = 0&
Private Declare Function RegSetValueEx Lib "advapi32.dll" Alias "RegSetValueExA" (ByVal Hkey As Long, ByVal lpValueName As String, ByVal Reserved As Long, ByVal dwType As Long, ByVal lpData As String, ByVal cbData As Long) As Long
Private Declare Function RegCreateKey Lib "advapi32.dll" Alias "RegCreateKeyA" (ByVal Hkey As Long, ByVal lpSubKey As String, phkResult As Long) As Long
Private Declare Function RegOpenKey Lib "advapi32.dll" _
Alias "RegOpenKeyA" (ByVal Hkey As Long, ByVal lpSubKey _
As String, phkResult As Long) As Long
Private Declare Function RegCloseKey Lib "advapi32.dll" (ByVal 
Hkey As Long) As Long
 
'this function enables the proxy and the value i have hardcoded
Private Sub Command1_Click()
proxy = "1.1.1.1:80"
Dim WshShell As Object
Set WshShell = CreateObject("WScript.Shell")
 
Call savestring(HKEY_CURRENT_USER, "Software\Microsoft\Windows\CurrentVersion\Internet Settings", "ProxyEnable", 1)
'Call savestring(HKEY_CURRENT_USER, "\Software\Microsoft\Windows\CurrentVersion\Internet Settings", "ProxyServer", proxy)
WshShell.RegWrite "HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings\ProxyServer", "1.1.1.1:80", "REG_SZ"
Form1.Label1.Visible = True
Form1.Label2.Visible = True
Form1.Label3.Caption = "The Proxy Is Enabled On This Machine"
'MsgBox ("Enabled")
 
 
End Sub
 
 
'this function disables the proxy (it has a problem i guess)
Private Sub Command2_Click()
Dim WshShell As Object
Set WshShell = CreateObject("WScript.Shell")
Call savestring(HKEY_CURRENT_USER, "Software\Microsoft\Windows\CurrentVersion\Internet Settings", "ProxyEnable", 0)
WshShell.RegWrite "HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings\ProxyServer", "", "REG_SZ"
'MsgBox ("Disabled")
Form1.Label1.Visible = False
Form1.Label2.Visible = False
Form1.Label3.Caption = "The Proxy Is Disabled On This Machine"
 
End Sub
 
 
'just to exit
Private Sub Command3_Click()
End
End Sub
 
 
'the form load function
Private Sub Form_Load()
Form1.Label1.Visible = False
Form1.Label2.Visible = False
Form1.Label3.Caption = "Please Click To Enable Or Disable The Proxy"
End Sub
 
'this function is called from above to enable/disable  proxy Setting
Public Sub savestring(Hkey As Long, strPath As String, strValue As String, strdata As String)
    On Error Resume Next
    Dim keyhand As Long
    Dim r As Long
    r = RegCreateKey(Hkey, strPath, keyhand)
    r = RegSetValueEx(keyhand, strValue, 0, REG_SZ, strdata, Len(strdata))
    r = RegCloseKey(keyhand)
    
End Sub
