Jul 29, 2010

I have two websites. One site contains nothing but image files. This is a sub-domain of the main website. The main website allows the user to search a database of information and displays that information. I create a grid with a link to the file. In my row_databound function, I want to check to see if that file exists on my other website. If it doesn't I remove the link, otherwise I leaves a link to that file. how to verify that the LINK actually goes to a file that exists?

Web Forms :: FTP Download - How To Check File Exists

Dec 7, 2010

What is the way to :

1) Check if a file exists on an FTP site.

2) Sample the size of that ftp file (3) times to ensure the file is ready for downloading.

We have some classes doing this already but they are using WebRequestMethods.Ftp.ListDirectoryDetails and then searching there in if file exists. I am hoping there are some clean ways to do this.

How To Check If File / Software Exists On Client Machine

Jan 6, 2010

I'm having some trouble trying to create a page for my web app. I'm not trying to write a simple download/upload page. Should also say that I'm not trying to write a complex one.What I need to do is in the PageLoad check if the user has installed one particular software and then show the right message to download and install OR run it from the user's actual installation. For this scenario I've tried to use different file upload controls to check if the file was on the client machine, but none of then can do this, since, for security reasons,I can't programmatically set the path and file to upload.
