to save the setting for the next time I run it

I am writing a program to reads the output of a DRO for a mill 24 bit data.
Will have a setup from / page or toolbar?
That sets the lpt address and converting values and (mm or inch and X or Y or Z. displayed in txt box.)
How do I get the program to save the setting for the next time I run it?
Will have up to 3 of the program running at the same time for X Y Z axis


Bill:wave:

You can use files or a db. Save your setting(s) to either, and then re-load upon startup. MANY examples of how to do this in the forum.
