VB print to pdf hangs randomly

[Paul_Collins]

I have a program that prints selected sheets to pdf using the Adobe Acrobat printer, suppressing the user prompt for a filename.

This mostly works ok but sometimes the program hangs during the acrobat distiller dialog.
Killing the acrobatray process with taskmanager lets the printing continue.
This only happens randomly, the same test set of sheets will usually print ok, sometimes not.

Here is part of the code:

FileName = OutputName(FolderName, view, ".pdf")
SetPDFRegistryKey(FileName)
MyPrintMgr.SubmitPrint(view)

I am using VB dotnet 2010, Revit architecture 2012 and 2013 on 64 bit Windows 7.

Anyone else had this and if so have you fixed it?

What I am want to do is have a timeout for the .SubmitPrint(view) line.

I know you can use Process.Start(name) to control an external process from the API but is there something similar that can be used for an API function?

Failing that I will trap the Windows ESC key as in Jeremy Tammik's recent blog....

Cheers

Finally fixed it!

Seems that Revit was starting to create the second PDF before the first one was finished. By waiting until the first PDF file existed and then another slight pause after that just to be sure all now works ok!
