Using The WebClient Class To Post Data?
Oct 5, 2010Not sure if any of you are familiar with hMailServer, however, I am attempting to automate account creation / editing / deletion by using the WebClient class to interact with hMailServer's PHPWebAdmin.
The problem I am facing is that I can't seem to retrieve the index page (http://localhost/hmailserver/index.php) after posting the login credentials.
Here's my code so far....
[Code]....
And here's the HTML for the login form...
[Code]....
what I'm missing / potential problems? Should the 'url' be the page with the form of which I wish to post data to, or the page I want returned? I've tried setting it to "....hmailserver/index.php" or to the status page ...hmailserver/index.php?page=status" but the response returned is always the HTML of the login page.

View 3 RepliesAccessing The Exact Data Sent Using WebClient.UploadData On The Server?
Jul 16, 2010I'm sending a large text string in the form of a byte array using the WebClient.UploadData method to a web site but I'm not sure exactly where to retrieve that data from on the server. I've read posts that say it is in the request object which I already know but how exactly do I retrieve the specific byte array I sent like in the following c# pseudo code:
byte[] dataSent = request.GettheByteArrayISentFromWebClientUploadDataMethod;
I understand that it may not be as simple as this and that I may need to do some other processing but can anyone post a code snippet that shows how I can get at the byte array that was sent?

Jul 2, 2010I am trying to use a WebClient to get the content of another webform in my project. I am using a WebClient because I want to do this asynchronously, so if there is a better way to do that, I am open to it.My webclient, however, is erroring with the "Illegal characters in path" error. Looking at it in the debugger, I see that this is the URI string I am using:

I don't see any illegal characters in it... what am I doing wrong?

View 4 RepliesWebclient 'thread Is Being Aborted'?
Oct 27, 2010I run a loop that downloads a lot of smal files from another website
try
Loopstarts
result = runData()
loop ends
catch ex1 as exception
End try
private function runData() as string
Dim wc as new WebClient
Dim str as string
try
str = wc.downloadstring(filePath)
catch ex2 as exception

THE Problem is if the file is not found in the RunData function I get 'Thread being aborted' error which stops the not only the function RunData() but also the loop is running in, so I get an error in ex2 as well as ex1. But I want the error to be captured in ex1 and stop, and not effect the loop.
I have read that you need to use Response.End to close the thread or not to capture the 'threadbeingaborted' expception.
BUT how do you do the response.end with a webclient??? (IN vb.net , asp.net 2.0 version
C# - Set A Timeout On WebClient.DownloadData?
Jan 29, 2010I'm using a third party url to determine the location of site visitors based on IP address.I use WebClient.DownloadData() to get the information returned by the url which is a one word answer e.g. as per http://api.hostip.info/country.phpOnce I have detected what country the user is in I want to either A) keep them on the current site and store the country in the session or B) redirect them to another countries site.What I'm worried about is WebClient.DownloadData() hanging so the user is waiting for ages and can't use the site. I'd thought about using DownloadDataAsync but this dosn't seem to be a solution for me as I don't want them to do anything till I find out the country (also seettp://stackoverflow.com/questions/271767/webclient-downloaddataasync-is-freezing-my-ui)Is there a way I can set a timelimit on my call to WebClient.DOwnloadData e.g. if it hasn't returned in 2 seconds,

Security :: Getting User Rights For Use In WebClient?
Jul 7, 2010I've got a site that users can use to check in and out documents. To check out a document, the user slects a file from a list, and clicks 'check out' . The document is taken from a 3rd party source control tool and placed in a dedicated directory on the server. Then, the file needs to be copied from this directory to a client directory the user has specified.
Copying to the Server is no problem.
I'm trying to use the WebClient objects DownloadFile method to write to the clients directory, but I keep getting "Access to the path '<path>' is denied.". I've set the UseDefaultCredentials flag to true, but no joy.
I'm obviously missing something, but I'm not sure what.

Error 1 'System.Net.WebClient' does not contain a definition for 'DownloadData' and no extension method 'DownloadData' accepting a first argument of type 'System.Net.WebClient' could be found (are you missing a using directive or an assembly reference?)

Asynchronous Use Of Webclient To Transfer Files?
Oct 24, 2010I have an objective to transfer some files which can be pdf, jpg and xml from one location to another. I am creating a handler based API for that. What could be the best approach for doing it? Should i return a byte array so that the client can pick the byte array and convert it back to file? Also the max file size I need to handle is 18 MB, so i have to make sure that the sizes are properly handled. Should I do an asynchronous transfer for that?

However, there are a couple of problems with this approach:
The Thread.Sleep() is locking up my Form. I still need to make my own Thread or use BackgroundWorker. (I would like to avoid this as much as possible)The DownloadFileCompleted event is being triggered after ALL files has been downloaded. I don't know if this is a side-effect of using

Is there a better approach to download files one at a time using WebClient.DownloadFileAsync?
C# - How To Detect That A File Was Successfully Received By A Webclient
Feb 18, 2010My question is similar to http://stackoverflow.com/questions/194579/how-to-detect-when-a-user-has-successfully-finished-downloading-a-file-in-php but I have to do the same using IIS, ASP.NET and C#.
None of the methods in the HttpResponse class provide feedback if the data was sent or not, TransmitFile just does its job (or not) and does not provide any means of knowing the result.I was thinking of using the .Filter property but then again, the filter is based on the HttpResponseStream which does also not provide any feedback.

the code I am using to download is:

When i deploy it on the server; and run my program, i get a message saying that download has completed successfully. But the problem is that the file is downloaded on the server machine in the filefolder (LocalFileFolder). I want it to be downloaded on the local machine. What is it that I am doing wrong?
