I omit to count the number of hours I have invested to solve this problem but here it goes: I have a report in crystal report and I need to connect it to the PostgreSQL 9.3 database but without ODBC, through a connectionstring or whatever, the case is that in the application I use the NPGSQL v3.2.1 connector to work with the database but I don't know how to make the CR report connect to the database. the IDE I use is VS2015 PROF and OS Windows7 prof 64bits. Can you give me a hand? Thank you.

I finally gave up trying to connect to a PostgreSQL DB with Crystal Report, but when trying to connect through the ODBC that had created the Crystal Report it gave me a problem and that is that I am using windows 7 64bits and used the odbc of postgreSQL 64 bits, this It is not compatible with Crystal Report so I had to install the postgres 32bit odbdc manager to install it I had to proceed as indicated in this link since if you do it the normal way the driver is not visible at the time of creating the ODBC. I hope you don't have to invest as much time as I have, almost 3 whole days just to find a solution to this problem. Arjjj :-(
