WebClient.DownloadFile Not Working Consistently?
May 23, 2012I am trying to write a program to download an image at certain time intervals from a website based on a start time, end time and the time interval. I am trying to use 3 timers to accomplish this. I want to be able to kick the program off and leave it running until I stop it. My code seems to work fine if I set the time interval for something like 2 minutes, etc. and sit and watch it, but if I set it for an hour and leave it alone, it gives me almost sporadic results.
I set it to start at 10 pm last night and end at 5 am this morning with an interval of 1 hour. It downloaded an image at 10 pm, 11 pm, 12 am, 1 am, 2 am, and 3 am and then there were no images for 4 and 5 am. I have tried this multiple times with different time spans, and seem to get sporadic results. Any insight would be greatly appreciated. Here is my current code:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
If TextBox1.Text.Length = 0 Or cmbStartTime.Text.Length = 0 Or cmbEndTime.Text.Length = 0 Or TextBox2.Text.Length = 0 Then
MsgBox("You must select an image destination, start time and time increment.")

404 Not Found Error On WebClient.DownloadFile (PDFs)
May 30, 2012I'm automating downloads. I was getting this error quite a bit using Webbrowser to navigate to a PDF (various PDFs at various websites). In other words the PDF was already on display in the browser when I called WebClient.DownloadToFile. I got a LOT better results when I desisted from WebClient and switched to this API (just pass in the two strings along with zeroes for the other parameters).

And yet Webclient seems oriented for only two entries (username and password). How do you set up the credentials for three entries? I hate to abandon WebClient, but at this point I just don't know how to make it work.

Or is it acceptable?I have looked into FileWebRequest, but thought WebClient looked easier to implement.

Feb 6, 2009The below code for some reason isn't working with filefront. I'm grabbing the URL that returns the file to download but the wc.downloadfile() code doesn't download the file. It creates an empty file called 100.rar in my temp directory on C: but doesn't have any data. Is there something I'm doing wrong or is filefronts redirect messing something up? If I put the URL I get with the fixUrl variable, it pops up the file to download in my internet browser fine.

Download Multiple Files At The Same Time From A Remote Server?
Aug 12, 2011Is there any way to download multiple files at the same time from a remote server? How I am doing it currently is I get a list of files from the target folder on the server then I loop through that list & download each file 1 at a time. For 100 small files it takes about 45 seconds. I'm guessing that the bulk of the time it takes is logging in to the server for each file to download, so 100 files means it has to login, download & logoff 100 times. Is it possible to login just once, download the 100 files then logout?

The above code will open a webclient, set the credentials (possible error?), create a stream of the entire page, and then load it into a string (str).I then scan through and look for what is needed (Gamerscore, Motto, Bio, etc)-in this case.This doesn't work however, it doesn't sign in.
VS 2008 WebClient Slow Image Download?
Jul 15, 2009I have a weird bug with webclient. I made an app a while ago which uses webclient to download a small thumbnail image.. and I rememeber when I first made it, the first time webclient was used to download the image it always took 15 sec+ to download it, but after the first it always downloaded quickly (in like 1 sec) .. but then the problem went away for me and it always downloaded fine.but now someone else who uses my app is having the slow image download problem apparently around 50% of the time it downloads the thumbnail images. so does anyone know what might be causing this? As I said, I don't have the problem any more on my comp - but I don't know why :s
