Hi all,

Frequently, my combo boxes are a list of codes that I use to set a filter. The codes are stored in a table along with their description. So for the recordsource, I use SQL:

SELECT code, desc FROM codetable INTO CURSOR tmp ORDER BY code

This works great if I want to force them to choose a code. But in some cases, I want them to be able to set the filter to everything. So, I want to put in the option to choose "". I don't, however, want to have "" as a code, since the codes are user-editable and they're likely to delete it. (Yeah, I know, I could get around that, but it makes things much more complicated)

Is there an easy way to add the blank choice? I tried setting the SQL, then in the init doing THIS.AddItem(""), but I get an error. I think it was data type mismatch, but this was last night, so I don't remember for sure.

I also tried, in the init, putting the SQL there, then doing AddItem to each record in tmp, and setting the rowsource to 0. I get the same error.

Any ideas?

-Michelle
