Crystall report using a DLL/datapipe

[Zak2009]

Hi all,

How do you connect a new crystal report to an existing DLL so that you can use the fields in the new report.

I've developed a few DLL that generate data for Crystal Reports. What does your DLL do. It needs to use COM to create an ADODB recordset object. If it doesn't you might need some custom code to wrap the Recordset around your DLL.

Then in crystal reports, select the COM data driver and give it the object name of the registered DLL.

For example my CrystalCalendar DLL registers an object called CrystalCalendar.DataProvider. The COM driver can then see the two recordset objects inside that DLL to use as a data source.
