OLE DB Connection problem with Crystal Reports 9 RRS feed

  • Question

  • I have a C++ application that was implemented as OLE DB provider. When I create a report using Crystal 8.0 or 8.5 using OLE DB I connect to my application (it is displayed in the list of OLE DB (ADO) providers) and generate reports. When I try to do the same with Crystal 9, I have a problem: As well as in Crystal 8, I select to create a new connection, select OLE DB and select my application as a provider, select the data link file where I list the login and password information, then press "Next" and am gettiing stucked with the "Data Source" dialog.
    My provider does not support the data source and with Crystal 8 and 8.5 I connect to my application without any problems. Does Crystal 9 require OLE DB provider to support the Data Source explicetly?
    I checked all the latest Microsoft OLE DB specifications and my provider supports all "required" by Microsoft interfaces. Does anybody know what is different in Crystal 9 that prevents it's connection to working OLE DB provider, while Crystal 8 and 8.5 work?

    Thank you very much for your thoughts and help.

  • Hello,

    The query engine did have changes starting in Crystal Reports 9.0 and it sounds like this is affecting you.

    To dig into this further I feel that you will need to contact Technical Support:

  • We did contact the Business Objects customer service, but after several days of diagnostic questions they dissapeared, while we cannot find the answer to the only question we have: "What has been changed in Crystal 9 what stops OLE DB providers working with previous versions of Crystal Report to function?" The Crystal 9 and 10 crashes during the connection process.

    Maybe Business Objects does not want to admit that there is a bug in their new functionality and that could explain their calmness?

    Thank you anyway.
