I'm writing an application that has to open a preexisting BDE database that has been saved by a third party. In this application, I currently have a TDatabase ( DriverName: STANDARD) with path set correctly in Params. I can now set Connected to true without an error message. There is also a TTable with DatabaseName set to the values of the TDatabase and TableName set to the.db-file that lies in the folder (the name was automatically filled in, I only hat to select it). Now the problem: If I set Active to true, an error message complains about missing access rights for C: PDOXUSRS.NET.

I know I could set another path using BDEADMIN, but I need to solve this in my application - I can't expect every customer to do this change. Furthermore, I have a test machine with the third party application running - it can access the database without any error, while my application throws the aforementioned error. This leads me to the suspicion there might be a workaround. Is there such a workaround? I only need read access to the database. Solved it thanks to the Thank you very much.

The problem occurs when accessing the file C: PDOXUSRS.NET, which is used by the Borland Database Engine (BDE). It is caused by improved security in Windows Vista and Windows 7. Access to files in the root directory of the system drive.

It pointed me to the possibility of changing the NET DIR in code: Session.NetFileDir:= MyCustomTempDir; After doing that, Table1.active:= true works and the data shows up in a connected TDBGrid.
