Hi Experts,
  Hopefully someone has run into this one before.  I have a VB.NET process that sometimes requires an existing PDF to be deleted.  Several files may be open at one time.  For example, say I have File1.pdf, File2.pdf, and File3.pdf all open.  During execution of my application, I get to a point where File3.pdf needs to be deleted.  If I try to do this while it's open, it obviously will error.  My question:  How do I check to see if File3.pdf is open and, if it is, how to I close it?

Thanks Experts!

I think you could cycle through all the open windows and close the one appropriate to the file that you want. This however would be dependant on Acrobat having something in the windows titlebar that is recognisable.

I am going to dig through some old code to see what I can find.

Try deleting it. if you are unable to delete and get an access exception, then it means it is open.
Now if you are sure that it is open in Adobe Accrobat, do something like in this post to get the process and send the Close keys like Alt- F4

Are you using a Acrobat reader?

Since I can tell if it is open or not, I think I will just ask the user to close the open pdf file.  That way, if they had it open to make changes, they will have the opportunity to save it as a different name or whatever they would like to do.

Thanks for the suggestions.
