Michelle,

I put a 0, Unknown item in the codes table. In some cases I disable that line in the cbo so it can't be selected. The cbo class has an mlAddUnknown flag that I can set for cbos that need that feature. If it is set I add that element to the cbo array.

>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)
