Releasing displayed pdf files in webbrowser control - c#

I have a webbrowser control in my winforms application to display a selected pdf file, after this i want to move the pdf file to an other location.
When i trie to move the pdf file it is giving me an error that the file is in use. I tried to make the webbrowser navigate to a other page before it is moved but it still give me this error that the file is used by an other process.
How can i release this pdf file so i can just move it? Disposing the webbrowser didn't do the trick.

They say "Adobe Acrobat and Adobe Reader are designed to continue running for a few minutes after you close the browser window in which you viewed PDF files."
The workaround for this seems to be :
Copy the PDF to a temporary file and display it, and then when you navigate away, it doesn't matter if AcroRD32.exe holds onto the PDF for a few minutes because you can still do what you need with the original!

The following code releases for me the pdf file, which was displayed in WebBrowser, so I can move it:
webBrowser.Navigate("about:blank")

I have had a similiar problem, which was that the form with opened pdf file in browser was hidden and then a new instance of the form was opened, which triggered the same file locked error. For me Disposing of the WebBrowser control just before hiding the form helped.

How to access PDFs from a DLL and display it on Adobe PDF Reader Control in WPF?

I have a WPF Window which should display PDF files which I've embedded into an DLL file. (So that it won't be accessible and visible from outside, also to keep it clean as there over 1000 files).
I was able to get the file locations by this statement: pack://application:,,,/SampleClass;component/PDFs/
But when I give this location to Adobe PDF Control like this: axAcroPDF1.LoadFile(fileloc). It is not loading anything. So is there any proper way to access it? or another way to embed files safely?

Load PDF in WebBrowser control

I have a small C# application where I load a PDF into the Web browser control which I named webBrowser. When I load it, it starts in the Acrobat Reader witch was set as my default viewer.
The problem I have is that when I change the default viewer for my system, in the webBrowser the PDF will be still loaded with Acrobat Reader.
My code:
webBrowser_.Navigate(filePath);
Any idea how to solve this issue?

How to open a PDF file by using Foxit/Adobe in full screen mode?

I need from my C# application open a PDF file by using Foxit Reader or Adobe Reader in full screen mode. Manually, I do it typing F11 in Foxit Reader and CTRL+L on Adobe Reader. This changes the current file view to "full screen" mode. But programmatically, I have no idea how to do this! Thanks in advance.
as I'm opening the pdf file:
Process.Start(filename);
You can use SendKeys to send F11 or CTRL+L to the PDF application after you run it.
Alternatively, Foxit or Adobe may support commandline parameters to open in fullscreen mode. If you don't mind changing to SumatraPDF, I do know you can pass -presentation $file.pdf - opens a PDF file in presentation (full-screen) mode. See the manual for details.
Also, in addition to using the other solutions, you could open a Windows Form (or WPF Window) with a WebBrowser control and point it at the PDF file. The PDF file will open in the web browser control. Just set the Windows Form Properties to be Maximized with no border, and that should be the key to getting what you want without messing with Process.

You need to change Acrobat Reader's settings so it will display PDF files on the browser itself.
