>>I've been out of VFP for several months and have forgotten a few things about the environment. If I have 2 tables open with a form but with no relation set between them and one of the textboxes on my form will display a field from the secondary table based on a field from the other, can I use a select statement to show the corresponding value based on a key field in the current record ? I did this with a combobox I used a select statement into a cursor to prevent changing the current work area.... can I do a similar thing with a textbox ?

Hi Evan,

Thanks for the response. I guess your question is why am I not using a relation in the Dataenvironment..... have'nt used such a thing in any application I've wrote to date and I tend tobe a creature of habit.... I'll try it and see how it goes.

I thought a relation might get in the way ie. in my case I've got a Purchase Order Header file that holds a key value for the Vender Master and thought if someone deletes the Vender Code that's in the P.O. Header Master it could cause problems with some open P.O.'s.


Again Thanks,

Don
