You would also need a mechanism for isolating your car from the resulting emp.

I've kind of come to that conclusion and implemented a solution to do that, thanks for the reply. Simon Minich

I have a report that needs printing, it's over 6000 pages (A4) from a dataset built in memory. I'm using the "normal" reportviewer control, and the generation of the report to the viewer seems fine, however when the report is sent to the printer it crashes after about 2000 pages, sometimes throwing an exception in GDI, sometimes (I'm not sure why) silently (ie stops sending pages to the printer). Having watched the memory usage on the machine that this is running on I discovered that it's not running out of memory (as I first assumed). Does anyone have A. Any idea what is going on and how to get around it, or B. A reporting tool that's better suited to printing (not saving to file) very large reports. Thanks Simon
