>1. How can I get a unique object id in a project or in a .exe file.

What good would this do? And exactly what ID are you talking aobut, the onein the PJX file? At run-time, you shouldn't worry about a project file at all, consider it as non-existant to the exe.

>2. How can I get the a fisical file name from a form included in a project or in a .exe file

I would suggest using an form manager to store the file name when the form is opened instead of getting it later on.
