Hi John!

If this is a fact here you won't find
anybody to solve this issue.
An error you should post on the official
support pages 'cause here it's only a
user-user-forum ;-)

Can you use Windows task manager to monitor to memory usage to see if a leak is in fact occurring or that QuickPDF is running out of memory when you are merging a large number of files with images.

I use many threads to merge some more than 500 tifs to one pdf files.

so raise "Out of memory" error.

when this error occurs, my program can't do anything, I must restart my program.

so I want when this error occurs, i need close all document and release the memory, how can i do?

what about below code?

With g_PDFLib

While .DocumentCount > 1

.RemoveDocument .SelectedDocument

Wend

End With

Set g_PDFLib = New PDFLibrary

which one can release all the memory PDFLibrary use?

Thanks!

Check out how many loops are always okay,
keep this loopcount in your mind,
Use a g_PDFLib.Free after the loop,
then the next "New PDFLibrary"...
Something similar should work for you.
