Je suis un vrai galèrien; je ne m'en sort pas de cette impression, j'ai bien regardé du coté FAQ RAVE:

Tip #75 - "No DATA Link Drivers have been loaded..."

Cat


Rave - Data Connections
Question


  • I get an error message “No DATA Link drivers have been loaded …” when I try to preview a report that uses a database connection. Previewing the report from the RAVE designer works.

Solution


  • This occurs when you call one of the execute method(s) of the RvProject, like ExecuteReport. What you need to do is include the appropriate RVDLXxxx unit in your uses clause. The xxxx is for the specific connection you are using for your database connection. This will register the datalink driver within your application. For example, RvDLADO for the ADO driver RvDLBDE for the BDE driver RvDLDBX for the DB Express
Mais je n'y comprend pas grand chose des Uses;

Moi de mon côté j'ai créé une Lib avex implib de leurs dataLinkADO.DRV que j'ai lié au projet ... mais toujours même message:

"No Datalink drivers have been loaded, use DatalinkADO.RVD driver file for the RaveServer/ide or include the unit RvDLADO for application
Donc si quequ'un sait...
