Hi Andrew;

   Very easy ... please have a look at either the Ink Picture and/or Ink Edit controls for this type of functionality.

HTH

Hi Andrew;

You should save the "Ink" part as that will be the actual signature vs the picture which could come from your tablet's camera for example. The "ink" - like the picture - would be stored in a Blob DB column (Long Binary in S.A.). Thus using the UpdateBlob and Select Blob DML statements.

Tip: Another alternative is to use the InkPicture control based DataWindow. The the DWO will perform the Blob DML commands for you.
