Limit Output Of WebClient.UploadValues?
Mar 3, 2009A situation occured where this service had a critical error and instead of returning aprox. 200 bytes of info it normally does, it returned some huge amount of data causing the statement (highlighted below) to fail with "System.OutOfMemoryException".
The actual real problem is with the SMS service provider and they are fixing the problem. But, I wanted my call to fail elegantly rather than cause an OutOfMemory exception. In investigating a means to achieve this[code]...
Using The UploadFile Webclient Method?
Jun 3, 2010I am trying to use the UploadFile WebClient method to a HTTP server which is operating on a device, however when I do this from my code at the client end (a PC), the server crashes. If I upload the same file from my browser on the PC to the same device running the same server, it works just fine. When I track the code on the web server there appears to be a difference in the header which is sent to the server. It is a 'Post', however the filename doesn't seem to be there. Is there anyway of reading the data that the UploadFile method sends?

FTP Switches FTP.UPLOADFILE
Jan 26, 2010I am utlizing a piece of code for an FTP upload process that we want to occur when the check mark is checked, The download function (virtually same structure) works extremely well and without any issues. But the uploadfile function merely creates a file on the destination path called what it should be called, but does not upload any information. I think there is some uploadstream that I have to invoke which I am not. This is just the code starting at that process.
ftp.Method = System.Net.WebRequestMethods.Ftp.UploadFile
'If we were using a method that uploads data e.g. UploadFile
'we would open the ftp.GetRequestStream here an send the data

Jan 20, 2012[Code]...
This code is put within a timer that executes every 3 seconds. ( instead of a while loop ) Whenever I run this code, the program takes time to upload the files in the folder to the ftp server, and it becomes (not responding), but it doesn't stop working, after the "not reponding" message, it reponds, but then it becomes not responding.. this is making the uploading process very Slow. I've heard so many things about application.doevents() and Threading and etc.
My.Computer.Network.UploadFile Fails To Pass Credentials?
Jan 11, 2011Dim LogonCred as net.credential= New Net.Credential(userid,password, domain)
Dim DestUri as Uri=New Uri(file://192.168.86.1/c$/Program Files/Test/Test.xml)
My.Computer.Network.UploadFile("d:Test.xml",DestURI,LogonCred,False,3500)
This passes credentials of my local machine (which is not part of the domain) instead of passing the LogonCred.Is this function just broken? Or is it my code?

Webclient.DownloadStringAsync?
Jun 20, 2012as per usual i am a little confused. I know DownloadStringAsync runs on a threaded pool with a default min and max threads limit, but what confuses is how would i call DownloadStringAsync say for example ten times.Example.I have an array with 10 URLS. Surely i would not use a for each loop of the array index to pass the url address while each time calling DownloadStringAsync(New Uri("someArray(index)") surely we can pass say a range of items from the array and let DownloadStringAsync decide on the threaded pool how many to process each time?

View 2 RepliesThreaded Webclient Still Slow?
Nov 24, 2008Here is my webclient class that I am using to check multiple web sites at the same time. I am threading the class so each thread is creating a new getHtml Class. It seems that it still is waiting on something, because it only returns about 2 pages per second, which is great, but I think it should return faster if they are truly running on separate threads.When i made a similar perl script it would return 50 pages in about 10 seconds so it was much faster than this webclient method, unfortunately I don't want a cli. Let me know what you think. I have tried setting the proxy to null, but that didn't do anything.

WebClient Download / How To Detech Bad URL
Feb 27, 2012We recently started playing with a vb.net 2008 WebClient on a Windows 7/64 workstation to download files from a web site to the local machine.It works except that we cannot detect if the URL is invalid. It doesn't throw an error. If we use Async it does trigger the Download Complete event but there was no file since the URL was incorrect.Is there a way to detect an incorrect URL?I also noticed that the events does not give you either the URL or the file?
