"http://www.tushar.com/articles" is not a real path. It's a virtual path. The local file system doesn't know how to handle this. You need to determine the local physical file path that is associated with this virtual path. You do this with the MapPath() method of the Server class. Also you should always deal with files in this way using a application relative path.

strRealDirPath = Server.MapPath("~/article")

This will get you the physical directory of the virtual directory "article" of your web application regardless of where the application is running. As long as you have the correct file access rights (in the OS and from the web server) you should then be able to save files to that physical path. Use the same code when retrieving the files.

I modified two sentence as
MyPath = Server.MapPath("~/article")

and

MyFile.PostedFile.SaveAs("Mypath" + c)

Please check the url
www.ieeevesit.org/upload/upload.aspx

It is not working giving me the error...

Plz check it..

Thank you for your reply

"An Error occured. Please check the attached file"

This error it shows.. You can check it on www.ieeevesit.org/upload/upload.aspx

planoie · July 26th, 2004, 09:22 AM

Unfortunately, that error message doesn't tell us anything. You need to be provide with the exact message from the exception that is occurring in order for us to help you.

Why do you have "MyPath" in quotes? It's a variable. Try this:

MyFile.PostedFile.SaveAs(Mypath + "\" + c)

Hi, is it possible to pass a variable to the Path
in the section of your code

Server.MapPath("VariableFromForm\\")

if (strCurrentFileExtension == ".gif" || strCurrentFileExtension == ".jpg")
{
objCurrentFile.SaveAs(Server.MapPath("books\\") + strCurrentFileName);

strMessage.Append(strCurrentFileName + " successfully uploaded.<BR>");
}

The Variable being a last name etc that was also used to create the directory?
