Hi all,

I need to check if a pdf file in the client machine exists ( to upload it to server).

I need to check C:\Myprogram\Temp folder for 20 seconds and if MyDocument.pdf comes in it I want to upload it to server.

Is there any easy way to do this?

Thank you.

It's not possible.  Browser security will not allow a web application to upload files from the user's machine.  The user must select the files.

A desktop application (file listener) can implement this type of feature.

Hi,

Unclear. If you meant from a browser you can't do that for safety reasons. Only a user can select a local file that is then uploaded to your web server.

From where comes that PDF file ? Rather than being produced on the client side and uploaded it can't be created directly on the web server ? (it's not a file printed locally to a PDF printer using server side data ????)
