[RESOLVED] Check for file on web and Also exit a loop

How would i check to see if a file exits on a website before attempting to download it?

Also in my code ive enclosed the instructions in Do loop and if the file doesnt exist i want to skip the code and loop to the next file.

Try to navigate to that file. If the browser returns 404 - File not found, you know that the file doesn't exist. So in that case, skip to next file (put the entire block in an If...End If).

Im using a class i wrote to go through a list and download the according file but i want to check to see if the file exists first. How would i check to see if it returned a 404 error?

TRY/CATCH should return an error if it doesn't exist.

I know of that method also but thats not my main issue here. Im trying to figure out how to continue looping even though the exception is being thrown and until it finishes looping then it exits.

vb Code:

Do While i < 0
            'code goes here
        Loop

Take that as an example. If i was 3 and i wanted to skip all the code on the first loop how would i do it? Like a 'next loop' kind of thing?

If you want to skipp an iteration in a loop, "Continue" is the keyword. The following code will skip 1 iteration when i = 3.

Code:

Do while i < 5
    If i = 3 Then
      Continue
    End If
    'Do your stuff here

    i += 1
Loop
