That URL was wrong in your post as it included the closing paren. Oddly, Eudora excluded it in this reply.
SETs often have global effects which make their local use frustrating.
I have not found it so, but one must be careful.
If I change a global setting SET (as opposed, say, to a SET ORDER), I either set the setting back as soon as I can or I have a procedure for doing the modified function requiring the different SET value. One must be careful about this stuff.
Three things:
- If you were rewriting the app, you'd store a "Data Directory" in your
global settings table and precede all your file open commands with that. That makes it INCREDIBLY easy to have a test mode that just switches that setting. But you're not re-writing your app, so...
I did that for a few programs where I needed to get to a different set of data. I am glad that it was only a few.

Mayhaps your email reader parsed it wrong, as I sent plain text and it works fine on my end.

Well, OP had a classic case, where the SET is saved, changed, and reset in a very small snippet of code, but if other code runs in the meantime (timers, in that case, or menu code or LostFocus events) that depend on the global setting, confusion results.
Gene, The problem if you are using GetFile() is that if you use the set default then open the dialogue and then keep the dialogue open for a few seconds, any background process/thread will pick up the new default location before you set it back after you close the dialogue.

Hi Dave:
I think that have a simple solution for the GetFile() problem. Try this:
oo = CreateObject("visualfoxpro.application") oo.DoCmd("cd 'c:\desa'") ? oo.Eval("getfile()") oo.Release()
Works ok and do not change main VFP default dir.
