Thread Subject: date validation

I am trying to validate whether an input on a GUI is a date. The datenum function returns errors if it is something other than a date. How do I alert the user to only enter a date without command-line errors showing up (I want to compile the program eventually)?

Use a try-catch block around your datenum call and in the catch block, put an error/warning dialog that will point out that the input expected is a date format.This way, any error generated will be caught in the 'catch' block and your program can elegantly throw the error instead of terminating at that point.

See help try
        help catch
        help errordlg
