Good morning Guillaume,

I see. You determine on the input of your DLL. I try to figure out if a file opend by some process is included or not - this seems to be harder.
The crushing point is, that my tests (using DBF()) show me a path fo the included files as well. Since this path is the one where the table is collected from, I have no idea how to figure out if I have opend the included or the external. All what I know is that a include file shows ISREADONLY() .T. under all circumstances - but to compare with an external it is not of help.

Anyway, like you I normaly know if I open an internal file. So there seems to be no need to go deeper in this.

>>Well, suppose you had a DLL which does all the handling of opening tables for you. That way, you could use the DLL in all your applications.

>>why do you need to know that? I figured out that is very tricky to know that a file opend is included under all circumstances , but maybe a specific workaround will do. Anyway, all of may possible ideas will work after openning the table. But you can close it again?
