Question How to get Webbrowser to release file

[bwwilson]

Hello,
I am writing my first vb.net program that displays a .pdf file in a webbrowser control. I have setup a routine that moves the file to a different folder. The problem is I get the following error: "The process cannot access the file because it is being used by another process." Is there a way to release the file from the webbrowser so that I can move the file.
Thanks,
Bruce

Me.WebBrowser1.Navigate("about:blank")
Do Until Me.WebBrowser1.ReadyState = WebBrowserReadyState.Complete
    Application.DoEvents()
Loop

Hi,
Thanks for the reply. I tried the code you posted and got the same error message. This seemed like such a great fix.

I tried it also and had no problems moving the hosted pdf after that. I have no other suggestions.

Acrobat.exe is the culprit

It's a new day so I thought I'd take a wack at getting my program to work again. With the code to go to a blank page and wait until the execution was complete in place, I tried it again, with the same result. I brought up task manager and killed the Acrobat.exe task and the file is released and I can move the file to its destination folder. So I guess the question is, how do I kill the Acrobat.exe process along with navigating to a blank page.
Thanks,
Bruce
