We are printing multiple documents to a Distiller printer from within a VB app. We are using the AcroExch.AVDoc print command to do this. As each document prints, the memory allocated to acrodist.exe increases until we get the generic Windows "running low on virtual memory" message.

I tried killing the AcroExch object and re-instantiating it but the acrodist.exe remains running. Is there any way to prevent/circumvent this memory leak (if that is what it is)?

There is also a memory leak using the GetNumText function of the CAcroPDTextSelect object. Every time the function is called, the amount of memory used by Acrobat.exe grows by about 200K. I also noticed that each time you do a find within Acrobat, the amount of memory used increases... this can be seen by viewing the memory usage in Task Manager.

In VB, I had to destroy each acrobat object prior to iterating to the next page.

Yes, I keep a counter and destroy the acrobat object every so many iterations, also. But even though the acrodist.exe is started by the Acrobat object, destroying the Acrobat object doesn't kill the acrodist.exe. It stays out there. Even after stopping the VB process it is still out there.

How do you destroy the acrobat object? I'm also working on a VB app and acrobat.exe hangs around in my task manager until I close the vb app itself.
