Stefan,
Dear Peter,
It's Patrick, btw, not Peter
I still do not see how you connect to the database / databook.
In your last post you mentioned a few times "dxdb" is this the application "dxdb.exe" from here:
C:\MentorGraphics\EEVX.1\SDD_HOME\common\win64\bin
No. I was using dxdb as shorthand for DxDatabook. You will never interact with the executable dxdb.exe. Forget that it exists; you don't need it at all.
I also do not know, how you "fill" the file you mentioned in one of the previous posts
my_db_path = "C:\my_db.accdb"
con_str = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" & my_db_path
As Matthias indicated, you need to find out what database DxDatabook is using as a source for its data. DxDatabook does not hold any data at all. It is just a window into another data source. I suggest that you go talk to the person at your company who is in charge of the setup and configuration of your central library. That person should know all about the external database DxDatabook is using as a source. Where it is located, what application it was created with, the table structure, and do on. You will need to know all this in order to make your own window to it.
