Title: LazReport multithread
Post by: cappe on June 02, 2016, 06:03:06 pm

How do I create a report with LazReport inside a thread (TThread) with TfrdBDataset and export it with TFrTNPDFExportFilter? Where can I find a code sample?

The problem that gives me is that the second generation of the report returns me the following error:

EParseError
Udefined symbol: FirstDataSet."Name"
in file "lr_class.pas' at line 8982

While the first time the report is generated correctly.

The error occurs only with reports connected to a database, and no database works correctly even to succeeding generations to the first.

How can I solve it?

Another question, where do I find the LazReport manual?
