That did the trick -- thank you very much. It seems the file is loaded... not that it is being displayed of course.<br>
<br>
Where could I find more info on where to go next from here (like, say, actually displaying the data in that file I just loaded)? Is there something that documents the high-level architecture/overview for Paraview, in particular for people interested in custom
applications? I have used VTK in the (distant) past, and I'm assuming that Paraview follows the same concepts (pipelines, etc), but not quite sure where to find that info.<br>
<br>
Thanks,<br>

Try calling the following before the pqLoadDataReaction.<br>
<br>
vtkSMReaderFactory* readerFactory =<br>
vtkSMProxyManager::GetProxyManager()->GetReaderFactory();<br>
readerFactory->UpdateAvailableReaders()<br>
<br>
Does that help?<br>
