Reading data from online text file...

[Cobra220]

I managed to figure out how to read data in from a text file in my program directory. How can I access a text file that is online?

try{
				 StreamReader^theReader = gcnew StreamReader("[URL unfurl="true"]http://www.whatever.com/file.txt");[/URL] //not the actual address, of course
				}
			catch(FileNotFoundException^g){
				MessageBox::Show("File Not Found Exception:\r\n\r\n" + g, "alert", MessageBoxButtons::OK);
			}
			catch(ArgumentException^f){
				MessageBox::Show("Argument Exception:\r\n\r\n" + f, "alert", MessageBoxButtons::OK);
			}

When I run the program, there I get the argument exception error.
What did I do wrong?
