I have a program that reads and writes values to the registry.
My program works just fine on windows t but not on windows 8.
the function I use is as follows:
If the entry does not exist it creates the entry and sets the value. On windows 8 I get the following error
System.NullReferenceException was unhandled
HResult=-2147467261
Message=Object reference not set to an instance of an object.
Why does this work differently in windows 8?
Does anyone have a solution?
Thanks in advance

Public Function ReadRegistryValue(ByVal MainKey As RegistryKey, ByVal sKey As String, ByVal sKeyName As String, _ ByRef oNameValue As Object) As String Dim rkKey As RegistryKey Dim Value As New String("") Try 'open the given subkey rkKey = MainKey.OpenSubKey(sKey, True) 'check to see if the subkey exists If rkKey Is Nothing Then 'it doesnt exist 'throw an exception rkKey = MainKey.CreateSubKey(sKey, RegistryKeyPermissionCheck.Default) 'set the value of the subkey rkKey.SetValue(sKeyName, oNameValue, RegistryValueKind.String) 'Throw New Exception("The Registry SubKey provided doesnt exist!") End If 'get the value oNameValue = rkKey.GetValue(sKeyName) Value = oNameValue.ToString Catch ex As Exception MessageBox.Show(ex.Message, "Error: Reading Registry Value", MessageBoxButtons.OK, MessageBoxIcon.Error) End Try Return Value End Function
If the entry does not exist it creates the entry and sets the value. On windows 8 I get the following error
System.NullReferenceException was unhandled
HResult=-2147467261
Message=Object reference not set to an instance of an object.
