Having trouble with stdregprov and uintvalue..

[Text]

I'm trying to invoke the createkey method under StdRegProv but I can't seem
to get the first
imparam correct

it says that "Value was either too large or too small for a UInt32 when it
processes current_user."

how do I pass a UInt32 value? Msdn has it listed as 0x80000001, but
vb.net won't except that. hDefKey only accepts uint32 values... or so it
seems.
Const HKEY_current_user As Long = &H80000001

Dim strkeypath As Object = "Software\Microsoft\Internet Explorer\Main\mas"

Dim wmi As ManagementClass

Dim md As MethodData

Dim RemotePC As String

RemotePC = "."

wmi = New ManagementClass("\\" & RemotePC & "\root\default:StdRegProv")

Dim inParams As ManagementBaseObject = wmi.GetMethodParameters("Createkey")

inParams("hDefKey") = HKEY_current_user

inParams("sSubKeyName") = strkeypath

Dim outParams As ManagementBaseObject = wmi.InvokeMethod("Createkey",
inParams, Nothing)

' Display results

' Note: The return code of the method is provided in the "returnValue"
property of the outParams object

Console.WriteLine("Creation of registry returned: {0}",
outParams("returnValue"))

Two answers:
- first and best one (to me): use C# which provides unsigned types (uint,
ulong, ...):
const uint HKEY_current_user = 0x80000001;

- second one: using VB, I wrote this horrible (but working) piece of code:
Const HKEY_current_user As String = "80000001"
...
inParams("hDefKey") = UInt32.Parse(HKEY_current_user,
System.Globalization.NumberStyles.HexNumber)

Maybe somebody will find a cleaner solution using VB ?...
