To Be or Not to Be: Verifying Files in ASP

If you're using ASP pages to manage files, you'll need to know if a file exists before you nuke it with a new copy. Use this efficient little code to find out if a file exists.

I am trying to access some PDF files in a database. I give the address of the file in the browser as an IP address. I am trying to create links for these files in a page. Before painting the link, I want to verify whether the link is valid and that the file exists. How can I do this in ASP?

Use the FileExists method of the FileSystemObject from ASP to check if the file exists.

Dim fs, strFileNameAndPath strFileNameAndPath = Your file name ' -- Use file name and path ' -- from the database. Remember to map it ' -- to the Web Server's point of view. ' -- Use Server.MapPath for help. Set fs = CreateObject("Scripting.FileSystemObject") If fs.FileExists(strFileNameAndPath) Then ' -- file exists else ' -- file does not exist end if
