Dmitry,

I don't know if it's the *best* way to do it or not, but I created one lookup table in SQL that handles all of my lookup needs. It's structure includes primary key, group type, display text, display order, include flag, return type, character return value, integer return value. Then, I simply created a few stored procedures to work with this table. The primary one simply takes a group type and an include flag as parameters and will return the display text, return type, and both return value fields in the order specified by display order. This way, I can return a list suitable for display in a combobox. I also created a custom combobox that has a custom property to specify the group type and it pulls the data (via the stored procedure) automatically. So, anytime I need to let the user select a lookup value, I simply drop this combobox on the form and set the one custom property and the ControlSource and I'm done. It works great for me.

HTH,
Chad

In the Clipper app they are all physically stored in one .DBF file. In SQL Server I am creating a separate table for each lookup, CompReference1, CompReference2,...CompCategory, and so on.
