File Is In Use

[ChristianW81]

Hi,

I write LaTeX Documents and create PDFs from it that are viewed by your great PDF XChange Viewer for Windows (Win7). However, your Viewer opens PDF files in a Deny Write Mode so that a second LaTeX Compilation Fails (mainly in TeXnicCenter and interpreter) because the PDF file is opened in PDF-XChange Viewer. I just forget it or I am too lazy to find the appropriate pdf file tab (lots of tabs) and close it. Therefore, is there an automatic way to do so?

As a solution I suggest, at least for Windows Vista and newer, you could implement the official Microsoft interface IFileIsInUse in the Viewer. On the MSDN link there is also an instruction on how to this. In this way, Windows Explorer and other Apps that supports this interface can show the additional possibilites "Switch to Windows" and "Close file" (both implemented by your app). In this way, the LaTeX Compilation can call the method "CloseFile" to close the file before it starts the compilation.
Because these methods are implemented by you (COM out of process), you can also show a "Save File" dialog before closing or even deny closing it (cancel).

Regards
Christian

Hello Christian,

And thank you for the suggestion.
We are considering some options for ver3 of the Viewer, but even now you can write a script that is closing the file in our Viewer, before applying the changes you have done with LaTeX.

Have a look at this topic.

Best,
Stefan

Hi,

thanks for your reply.
I hope this solution gets integrated into the new version since it is a great way to overcome the access denied problem in Windows (>=Vista).

And thanks for your suggestion.
Your solution is fine so far as it solves the problem at the moment (at least for me).

Regards
Christian

Thanks Christian - will endeavour to do so in the next major release if possible.

Thanks

Sorry I have to say this, but your great programm is quite useless for me because of this. And btw. Foxit Reader has been doing this, auto-updating with latex, for years...

Hello Roadrunner,

We can understand that this could be quite a frustration for LaTeX users, but we are doing all our best, and as John mentioned above - we will consider a read only mode for ver3 of the Viewer. Additionally if you follow the link in my post above, you could find some simple scripts which could make our Viewer useful by closing the files before saving changes made in LaTeX and then reopening it in our Viewer.

Best,
Stefan

Hi, Christian.

Currently you may open document in non-blocked mode by next command line:

PDFXCview.exe /A "nolock=yes=OpenParameters" "c:\test.pdf"

HTH.
