How can I verify the validity of recognised field values automatically?

Using the graphical interface of FormPro you can configure the following automatic verifications:

• Regular Expressions (e.g. \d{1,2}/\d{1,2}/\d{2,4} for a date, see Help topic Zone Properties)
• Minimum and maximum values (see Zone Properties)
• Minimum and maximum length of values (see Zone Properties)
• Look-up lists and database checks (see Zone Properties / Look-up List)

More complex verifications like database look-ups or contextual validation rules can be realised by using the application programming interface (API) of FormPro to create an add-on. There are no limits to your creativity when using this interface but it requires substantial knowledge about the C# programming language. At your request, we are happy to inform you about the possibilities of add-ons or create an add-on for your specific needs.
