DLL not unloading

aarondc

Hi there

after calling ViewerStart(...) and then later closing the application, the DLL is still loaded and hence the application does not fully close (eg: still appears in Task Manager).

I cannot find what you have done in the DEMO application to fix this.

Can you please advise what I should be doing to unload the DLL when the application is closing.

This has been very frustrating.

Thanks

Thanks for your mail - you told me that it was caused only when a competing product was used in same project.

If anybody has a small project which shows this behavior, please let me have it.

In http://wpcubed.com/forum/viewtopic.php?t=5675 this helped:

Try to add:
Code
if WPViewPDFDLLHandle <> 0 then
begin
  FreeLibrary(WPViewPDFDLLHandle);
//  f_set_lic := nil;
  WPViewPDFDLLHandle := 0;
end;
to your FormDestroy. It fixed the problem for me.

I was finally able to reproduce it. It will be fixed in next build. Itb was not caused by WPViewPDF but by GDI+.

Right now you can comment the line WPPDFViewerStop in the finalization section of WPViewPDF3.
