I'm downloading a file from my website using WebClient.DownloadFile(),I'm wanting to do it asynchronously, so my UI stays responsive, that would require me creating an array of web clients, is that bad practice? Or is it acceptable?I have looked into FileWebRequest, but thought WebClient looked easier to implement.
View 10 RepliesI have read about Network.Downloadfile and I think I understand it! I want to know if there is an easy way to test a files date modified before downloading it. I have a lot of files in the folder. I really want to "sync" the folder. I don't want to copy every file every time I want to only download the file if I don't have the file in the destination location or if I have an Old copy.

I seem to remember reading the MSDN somewhere that there was another method to download files from URIs other than using the webclient object. I'm trying to download some raw php files but every time I use the webclient object the server interprets them as an HTTP request and instead serves the default web page that the php file builds and not the php code itself.

I 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.")

I'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.

I'm trying to filter submitted web sites by attempting to browse them while bouncing the request off of OpenDNS. If the page received is the OpenDNS page, I'll assume the page shoudld be blocked.
How might I accomplish this task using the System.Net.WebClient class?
My program takes user input, replaces all spaces with "+", then inserts it into a search url for a specified web host. For example, the user enters:"How long is a foot?"
The generated URL (in this case I'm using dogpile.com) is:
"http://www.dogpile.com/info.dogpl/search/web?&q=How+long+is+a+foot"
This method has worked before for me, but now I just get an Internal Server Error every time the code is executed.

Or is there a better method?
