Marnitzg has the right idea. There's plenty of documentation for these commands in both the VB Help files and anywhere on the web (including this site; use the Search feature). These two commands will store a value in the user's Registry that can be altered and recovered at will. Here's the basics:

Code:
' Place some settings in the registry.
SaveSetting "MyApp","Startup", "Left", 50 

'This will return the correct value (50)
iLeftSetting = GetSetting("MyApp", "Startup", "Left")
If this app will be running as a multi-user app with a central set of values for all users, you might think about creating an ini file to hold those values (again, do a Search here).
