On which thread(s) does WebClient raise its events?

I can not find any documentation that specifies on which thread WebClient raises its events. I ran some tests and determined the following: If called from a UI thread (say from an event handler) the event handler will be executed on that thread. As a test, I added an infinite loop after the call to OpenReadAsync. The event handler was never called. If there is no UI thread, like in a console application, the event handler will be executed on a thread pool thread. In this case, if I wanted to provide some results the rest of the application, I would have to be aware of threading issues. Is this

问题 I have a web app with that is using JQuery to interact with my backend. The backend successfully accepts JSON data. For instance, I can successfully send the following JSON: { "id":1, "firstName":"John", "lastName":"Smith" } I now have a Windows Phone app that must hit this backend. I need to pass this same JSON via a WebClient. Currently I have the following, but i'm not sure how to actually pass the JSON. string address = "http://www.mydomain.com/myEndpoint; WebClient myService = new

Protecting client side logic & data

I am coding a data intense web app. So that means I cant be possibly doing any computations on sever- computation after every event involves huge data too large to be sent to sever again & again. So I have to do all execution & keep all data on clint side only. Currently I am using JS to do so. Is there a way by which I can protect my js files & data so that no one has (atleast an easy) access to it ? Is there some other way of putting (except JS) to put logic & data on client & conceal them ? thanks, Rather than using javascript for the client side logic, perhaps you could use an applet which

Silverlight Background Thread using WebClient

一笑奈何 提交于 2019-12-01 14:01:50
I'm using a WebClient to get infos asynchronously from my web service : wc.DownloadStringCompleted += DownloadStringCompleted; wc.DownloadStringAsync(service); I works fine, but I think the DownloadStringCompleted method is working on the UI Thread, and since i'm doing a lot of parsing there, my page takes a few seconds to appear. However, since I have so fixed data and a progress bar, I would'nt mind have it appearing instantly. How could I perfom this ? Thanks ! Use HttpWebRequest rather than WebClient . HWR doesn't return on the UI thread and so doesn't block it from updating. WebClient

Changing FTP from binary to ascii in PowerShell script using WebClient

问题 Simple PowerShell script. It downloads a file (in binary) with no issues. I need it in ascii. $File = "c:\temp\ftpfile.txt" $ftp = "ftp://myusername:mypass@12.345.6.78/'report'"; $webclient = New-Object -TypeName System.Net.WebClient; $uri = New-Object -TypeName System.Uri -ArgumentList $ftp; $webclient.DownloadFile($uri, $File); 回答1: The WebClient does not support ascii/text FTP mode. Use FtpWebRequest instead and set .UseBinary to false. $File = "c:\temp\ftpfile.txt" $ftp = "ftp:/

How to solve Gzip Magic Number Missing

主宰稳场 提交于 2019-12-01 12:48:47
I have a string that I Gzip on the server and download to a client using the WebClient class. When I try to uncompress it, I get the error message that the Magic Number is missing. I have tried both the GZipStream class and the ICSharpLib methods of solving this, so I'm at a loss. The compression/decompression works if I omit the step of downloading via the WebClient (using DownloadData which returns the data as byte[]), so I can only assume that there is some problem with the data getting truncated or corrupted some how, but since it's compressed data, I'm not sure how to debug this. Here's
