I'm thinking, that you can bring definitions of the numerical fields from SQL Server using Information_Schema.Columns view (the fields that participate in each particular form) and then compare juststem(ControlSource) against the cursor of such fields.

The only way I know how to do it is to create an array using AFILED() and search for the particular field in the array for the size. But I am really hoping for something better. I guess, I can create a number of form array properties for each table I need to find the field type. Then in the gotfocus() of the textbox search for the type in the corresponding array and set the format accordingly.
