RAP pass-through function

rbuser

I created a RAP pass-through function, but I need to access a TReport
Pipeline property, how can do this ?

I saw nothing in the demo report.

Thank you !

You'll need to pass the datapipeline as a parameter in the pass through
function. This way you don't have to put the pass through function in the
same unit as the report object. If it were, then you could hack around it
by referencing the form's report object's datapipeline propery, but that
would not be as portable as simply passing the handle to the pipeline from
RAP in the pass thrugh function explicitly.

In the ExecuteFunction you can reference the aParams parameter and get the
different parameters and type cast them:

lPipeline := TppDBPipeline(aParams[0]);

You can override HasParams of the pass through function to return true. See
myRapClass.pas file in the RAP tutorials section for an example.
