| | Read from Registry on Vista I'm using this approach to read from registry. Dim f As New RegistryPermission(RegistryPermissionAccess.AllAccess, _ "HKEY_LOCAL_MACHINE\SOFTWARE\SRS Enterprises\Coordinator\Settings") 'Vlad 02/12/2007 Dim f2 As New RegistryPermission(RegistryPermissionAccess.AllAccess, _ "HKEY_CURRENT_USER\Software\Classes\VirtualStore\MACHINE\SOFTWARE\SRS Enterprises\Coordinator\Settings") Dim pRegKey As RegistryKey = Registry.LocalMachine pRegKey.OpenSubKey("SOFTWARE\\SRS Enterprises\\Coordinator\\Settings") Dim val As Object = pRegKey.GetValue("CSSLQN") It works on Windows XP, on Windows Server 2003. It doesn't work on Vista Business. pRegKey.GetValue("CSSLQN") returns null. The key with value exists. What should I add to my code to get the value from a registry? Thank you Vovan |

| | Re: Read from Registry on Vista After the registry permission declaration you don't use demand or assert. So, you declare it but never use it Dim f As New RegistryPermission(RegistryPermissionAccess.AllAccess, "HKEY_LOCAL_MACHINE\SOFTWARE\SRS Enterprises\Coordinator\Settings") f.Demand() ' Personally I use ASSERT because at the end you can use f.RevertAssert(), but you cannot do that with Demand() Please try & post back -- Newbie Coder (It's just a name) |

| | Re: Read from Registry on Vista Thank you I tried both one by one. I still get null from the key.

| | Re: Read from Registry on Vista I found the sample of the code a couple of years ago. I replaced its values with my values and it worked right away. Since that I never had any problem with that code before Vista. I use it in Windows Service project. I tested it in Windows Form project. It works on Vista. So the same code does work in Windows Form project on Vista, in any project before Vista and doesn't work in Windows Service project on Vista. What's the difference?

| | Re: Read from Registry on Vista I guess they got more specific in what they would allow and not allow or what was conventional or not.
