Im making a program that downloads images, but if the image didnt exist IE 404 Error, how would i stop the program from crashing and saying [ Continue | Exit ] ?

 

oh btw this is my code:

       Dim File1 As String = site.Text & "/dir1/test.gif"
       wclient.DownloadFile(File1, save.Text & "\dir1\test.gif")

 

but if that file dont exist, it does 404 and then my program crashed and asks to continue or exit..

 

please help.

Why not use a Try/Catch statement...http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vblr7/html/vastmtrycatchfinally.asp

i dont want it to take me to the image i just want to know how to stop the program from crashing.

Is there any reason why using a Try ... Catch wouldn't work? It will allow you to handle the error however you see fit.

but how do i make it not crash on 404 error? what do i have to do?

[PlausiblyDamp]

Just wrap the call to the .DownloadFile method within a try ... catch block, did you even read the link coldfusion posted?
