问题
In my VB.NET project I want to save and get a registry value in "HKEY_LOCAL_MACHINE\Software" but I am only able to save and get it in "HKEY_LOCAL_MACHINE" but not software.
Here is my code:
For setting the value
My.Computer.Registry.LocalMachine.SetValue("Study", "1")
For getting the value
Dim RegistryCheck As String = My.Computer.Registry.LocalMachine.GetValue("Study")
回答1:
You have to verify if you have the permission to write (and also read) from HKEY_LOCAL_MACHINE. If you can't get the required permissions (which is quite possible), opt for HKEY_CURRENT_USER (My.Computer.Registry.CurrentUser). Anyway, you have to specify what kind of permissions you're requiring: Read/ReadWrite. See the overloads of the OpenSubKey() method. Two of them let's you specify these requirements. If/When you are granted the permission, create the subkey (CreateSubKey()) and then set a key value inside it (with SetValue()), specifying a value type with RegistryValueKind.
