If any of the items named in the GetSetting arguments do not exist, GetSetting returns a value of Default.
Because it operates under the HKEY_LOCAL_USER registry key, which is not active until a user logs on interactively, GetSetting requires that a user be logged on.
Registry settings that are to be accessed from a non-interactive process (such as Mtx.exe) should be stored under either the HKEY_LOCAL_MACHINE\Software\ or the HKEY_USER\DEFAULT\Software registry keys.
GetSetting requires Read Registry Permission.
This example first uses the SaveSetting function to make entries in the Windows registry for the application specified as AppName, and then uses the GetSetting function to display one of the settings. Because the Default argument is specified, some value is guaranteed to be returned. Notice that Section names cannot be retrieved with GetSetting. Finally, the DeleteSetting function removes all the application's entries.
' Place some settings in the registry. SaveSetting("MyApp", "Startup", "Top", "75") SaveSetting("MyApp", "Startup", "Left", "50") Console.WriteLine(GetSetting("MyApp", "Startup", "Left", "25")) DeleteSetting("MyApp")
