VBE (visual Basic Editor) variable

Hi

With an XLA file that load when Excel open, there is a new button in the vbe standard bar menu that appears. With the click of that button it pops up a userform that contain a TextBox that shows all the code that is present in the vbe XLA file. The problem that I have is that it always shows the code of only that XLA file. But, i would like to be able to see the codes of other vbproject. Meaning, that the one that i am seeing a the screen, is the one that i would like to list when i click on my button.
So my questions are: How, When, Where can I get the information that I need to use the ThisWorkbook.name of the window that I am looking at and pass it some how to my XLA project ?


That is my main problem. there is 2 others.

- The button sometimes only works once
- I cant come back on the same place before i click my button

Any help, critics, amilioration at all, will be appriciated !

Thank's

Philippe
