Whenever I open one of the Quantum Grid demos in Delphi XE Pro (on Windows 7 32-bit), the following error is displayed for every table (I think) in the project:

error message http://www.tranglos.com/img/qgerror.png

The message is:

Network initialization failed.
File or directory does not exist.
File: C:\PDOXUSRS.NET
Permission denied.
Directory: C:\.

I understand permission issues writing to c:\, but the result is that while I can build and run the demo projects, no data is displayed, which makes the demos rather useless. And what kind of database writes its configuration to c:\ directory in the 21st century anyway? 🙂 (Yes, I know very little about Paradox databases, but I won’t ever be using one either. I just want to learn how to use the grid.)

Using BDE Administrator I’ve tried changing the Paradox “NET DIR” value to a folder with write permissions on the C drive. Result: now the database tables cannot find their data:

Path not found.
File: C:..\..\Data\GENRES.DB.

…and the unhelpfully truncated path gives no indication where the files are expected to be.

Is there a way to work around the problem so that the demos can load their sample data correctly?

    Using BDE Admin to change the location for PDOXUSRS.NET helped, but it wasn’t sufficient. DevExpress did the right thing in specifying a relative folder for the data location, and the relative folder seems perfectly allright, but for some reason the DB can’t find it.

    Solution: under the \Demos\ folder find all the *.dfm files that contain the string

    ..\..\Data

    and replace that string with the absolute path to the demos folder. That done, all the demos open correctly.
