#Dialog help
I've got a dialog box that contains several edit text items and I need help
with a couple of problems. BTW – I'm using THINK C 5.0.
1) How can I restrict the number and type of characters the user can enter in
each item? (I only want to accept numbers, commas and periods.)
2) After I get the data from the item using GetIText I need to perform several
calculations. How do I convert a Str255 to/from a double?
Thanks,
Gary
