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!
