Registry issue
in [VB.NET]
|
From: Ron Hinds on 13 Apr 2010 13:15 I've been developing a Service in VB.NET. I set the serivce up to run under the NETWORK_SERVICE account. I need to store several parameters for the service to load on start from the registry. I tried to create a new subkey in the service's ket that is created at install time, i.e., HKLM\SYSTEM\CurrentControlSet\Services\MyService. My idea was to create a subkey called Parameters (like the Windows Time service does) and store my data there. But I cannot even open that key - it always returns Nothing - then I get an error missing parameter if I try to create it. So I figured I would just create it under HKLM\SOFTWARE\MyCompany\MyService. I get the same result. The only time it does not fail is when I use HKCU\MyCompany\MyService. But that won't be available for my configuration utility to make adjustments. It is appaerntly a permissions problem. Can anyone point me to a good Registry exampe in VB.NET or tell me what is wrong with this code? rplBaseKey = Registry.LocalMachine.OpenSubKey("SYSTEM\Services\MyService", RegistryKeyPermissionCheck.ReadWriteSubTree, RegistryRights.FullControl) If rplBaseKey Is Nothing Then 'Should never happen - key is created automatically on install rplBaseKey = Registry.LocalMachine.CreateSubKey("SYSTEM\Services\MyService", RegistryKeyPermissionCheck.ReadWriteSubTree) End If rplParamKey = rplBaseKey.OpenSubKey("Parameters", True) If rplParamKey Is Nothing Then 'Create the key if it doesn't exist rplParamKey = rplBaseKey.CreateSubKey("Parameters") End If
