Hello John A first step could be to capture the data in a control that ensures the data is correctly formatted. In the three examples below the format is fixed and ideal for a TMaskEdit control. In my document production package I accept data for arbitrary used defined fields and allow users to specify their format by having them specify the mask.
Your question is about display. I have not faced that question yet. If the data is properly formatted could you display the data as strings?

Examples are: dates stored as an 8 digit integer (YYYYMMDD) (want to display as dd-mmm-yyyy and I already have the code to format it how I want) IRD numbers - 9 digits displayed as XXX-XXX-XXX Bank accounts integers displayed as XX-XXXX-XXXXXXX-XX Credit card numbers displayed as XXXX-XXXX-XXXX-XXXX in each case stored as integers, but how could I intercept the display on displaying the data and after entry to reformat them like this? What do others do? For displaying I am hoping the answer is not just to store them as strings, as I still have the issue of how I validate entry.
