How to get file extension of uploaded file
Heres a simlpe one. How do i get the file extension of an uploaded file or any file for that matter without using any of the substring or split functions. I thought File.PostedFile would contain a property like that but it was not to be.
Thanks in advance.
As far as I know, the only way to get the extension is to parse it out...out of curiosity, why do you not want to use any of the string methods for parsing?
I totally agree with the previous response but thought I would add a few other options which *may* help, depending if they are usable in your situation. (Without additi...file uploader save file on server and in database and upload this file on client

I've got a fileUpload control on an aspx page that works fine for the accepted file type, .rpts, and brings up the correct error message for not allowed extensions such as .exes and .jpgs.
But .pdf files should cause an error message to be displayed, as only .rpt files are allowed to be uploaded, but instead it brings up a blank page like a web500 page.
Is there a known bug when attempting to upload pdf's?
Just in case,here's the only relevant code attached to the control:

Michael,If you are using the FileUpload control you can use the PostedFile.FileName property. If you need just the name and not the path, you can use Path.GetFileName(fileControl.PostedFile.FileName) Is this what you are looking for? ~Ben

I have a web aplication that needs to process file content (client
side) before uploading them to server.
May be I have to use file upload form and somehow read files and sign
them on submit event
I'm not sure how (and can I) do this in Firefox extension?
I prefer to use browser functionality for file upload rather than make
my own HTTP connection from my extension. I also prefer not to write
any user interface.

I use 2.0 with VS 2008
In my code I have put a file upload limit of 1 MB. But if I try uploading files greater than 4 MB, instead of showing the User Message, it does not execute any line of code. Instead it shows.
Internet Explorer cannot display the webpage
But if I try uploading files between 1MB+ and -4MB, it shows the user message correctly. Cant seem to figure out what the problem could be. Any hints?
Below is my codeDim path As String = Server.MapPath("~/UploadedFiles/")
