I'm using the latest release version of the driver dll psqlodbc-08_00_0101 with a report writing application called R&R Report writer. When a report queries the database for data to display, all of the varchar and text fields come back blank. After doing some research, the only evidence of the cause that I'm finding is that the cbValueMax for those fields is 1 instead of the actual length of the text buffer. Can anyone suggest a solution or where in the code I should look to fix this problem?

Hello,
You can use the version 7.x of the driver. Version 8.x of the driver
introduced this odd functionallity that returns blanks for all string data
if you work with some products. This happens to me with all tha applications
that use Borland BDE.
NOTE: I didn't try the last (libpq) version.
Regards
Miguel Juan
