About Editing the registry...{Self Resolved, fix included}

Ok this one has me kinda stumped...

I need my app to set a value in the registry under HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings

I need to set the key "Enable Proxy"'s value to and from 1 & 0. Here's the fun part, it needs to be a REG_DWORD and when I set it with my code it is setting to a RED_SZ.

I have tried a few different methods of setting it properly but it always accepts it as a string more or less and not a value. Here's some of the code I am using.

VB Code:

Function SetStringValue(SubKey As String, Entry As String, Value As String)
 
Call ParseKey(SubKey, MainKeyHandle)
 
If MainKeyHandle Then
   rtn = RegOpenKeyEx(MainKeyHandle, SubKey, 0, KEY_WRITE, hKey)
   If rtn = ERROR_SUCCESS Then
      rtn = RegSetValueEx(hKey, Entry, 0, REG_SZ, ByVal Value, Len(Value))
      If Not rtn = ERROR_SUCCESS Then
         If DisplayErrorMsg = True Then
            MsgBox ErrorMsg(rtn)
         End If
      End If
      rtn = RegCloseKey(hKey)
   Else
      If DisplayErrorMsg = True Then
         MsgBox ErrorMsg(rtn)
      End If
   End If
End If
End Function
 
Sub Command1_Click()
    SetStringValue "HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings", "ProxyEnable", 1
End Sub

Also, all the API's for the SetStringValue have been declared and the function works fine, just need it to set the value properly.

If anyone can help me figure this out I will be very grateful.

Thanx.

Ok I worked it out, I had to change a few things in there... For those interested here's the edited code from above I used.

VB Code:

    lHighDateTime   As Long

___________________________________________________
Function SetStringSrealValue(Subkey As String, Entry As String, Value As Variant)
Dim LngValue$
Call ParseKey(Subkey, MainKeyHandle)
LngValue = Value
If MainKeyHandle Then
   rtn = RegOpenKeyEx(MainKeyHandle, Subkey, 0, KEY_WRITE, hkey)
   If rtn = ERROR_SUCCESS Then
      rtn = RegSetValueEx(hkey, Entry, 0, REG_DWORD, LngValue, 4)
      If Not rtn = ERROR_SUCCESS Then
         If DisplayErrorMsg = True Then
            MsgBox ErrorMsg(rtn)
         End If
      End If
      rtn = RegCloseKey(hkey)
   Else
      If DisplayErrorMsg = True Then
         MsgBox ErrorMsg(rtn)
      End If
   End If
End If
End Function

Then to set the value you simply put:

VB Code:

SetStringSrealValue "HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings", "ProxyEnable", Chr(1)
 
'then to set it to 0 do this
 
SetStringSrealValue "HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings", "ProxyEnable", ""

So, yea, that was fairly easy to fix. :D
