writing/reading to registry

Hi, I have a login for all my programs that uses a XML file to store the regstraion code. So everytime the program is run it doesnt need to show the login screen. BUT this creates a problem everytime i offer an update because evryone needs thier registration codes again. So i want to store the reg code in the registry instead of the XML so that the udated program will just read the registry and it will then load up. So i need to know how to write the code to the registry and then read it. Thanks a lot!

Maybe this code can get you started. I found it at http://'http://msdn.microsoft.com/li...omregistry.asp


'Delete a key in HKEY_CURRENT_USER

Dim key As Microsoft.Win32.RegistryKey

key = Microsoft.Win32.Registry.CurrentUser.OpenSubKey("SubKey", True)

key.DeleteValue("Name")



'Create a key in HKEY_CURRENT_USER

Dim key As Microsoft.Win32.RegistryKey

key = Microsoft.Win32.Registry.CurrentUser.CreateSubKey("SubKey")

key.SetValue("Name", " Value")



'Read a key from HKEY_CURRENT_USER

Dim key As Microsoft.Win32.RegistryKey

key = Microsoft.Win32.Registry.CurrentUser.OpenSubKey("SubKey")

Dim name As String = CType(key.GetValue("Name"), String)

Ok thank you very much. I figured it out:bigyello:
