Hi All,
I am writing a program that converts english to metric torque for work. My question is what is a good way to do edit field checking so the program verifies a valid number is entered into the field and not alpha characters or punctuation.
Thanks!
Bob

Are you using the Windows CE version of PocketC or the Palm version?

For Windows CE you can set the edit field type to numeric only which will force the user input to be digits. You could also intercept the EN_KILLFOCUS notification message when the user steps to the next field, and validate the contents of the edit field at that time (setting the focus back to the field if the input wasn't numeric).

Thanks Guy,
I am using Palm OS and have been using Ccontrols to build the GUI. In the last day or so I have finally unzipped PToolbox, printed the documentation and your reply led me where I need to go to make the field numeric.
Thanks!
Bob
