Input Validation

Is there a method lurking about to validate input data in a text box to be
numeric or are you required on the PPC to loop through the string a
character at a time to perform the validation?

If you're using MFC, you may find the dialog data validation functions
(DDV_MinMaxByte, DDV_MinMaxInt, etc) useful.

Unfortunately my need is for validating the string in a text box in a form
Thank you for the try.

It is hard to believe that it is that unique a need.

The need is not all that unique. But Microsoft has provided no
"standard" method so we all write our own. I've come across other
"features" that are needed more often, are more painful to implement,
and are not available from Microsoft. (e.g. date conversion)

See a current thread called "Editbox" in
microsoft.public.win32.programmer.ui

I did is with a Try-Catch and just let the errors happen. Exception
handling is way much faster on the PPC then on the PC.

Is everyone addressing this issue on the PPC by "unlearning" the axiom to
not use Try-Catch as the standard method for simple input validation?
