Networkstream Connection Fails & Httpwebrequest Connection Not Reading Fast
May 17, 2012I am connecting to a data stream that pushes data continuously and when I tried to set up a network stream I just could not connect and kept getting the 'not found' error. I used the httpwebrequest with webrequest.keepalive = true and started to consume the data by reading into a buffer and then appending to a stringbuilder. Once the stringbuilder reaches max size I flush it to a text file. The problem is that I get disconnected from the data stream because I am not reading the data fast enough. I need to keep the connection open and read the data while ensuring data gets stored in text files. If I use method "CONNECT" it does not connect to the stream.
While (True)
webrequest = DirectCast(Net.WebRequest.Create(url), HttpWebRequest)
webrequest.Credentials = New System.Net.NetworkCredential(username, password)
webrequest.Method = "GET"
[code]....
should I increase the buffer size and if so what is the max? that would mean I can read more data at a time and keep up with incoming push. Disparate here.
ACtually also I noticed that it gets stuck on this line
numbytesread = responseStream.Read(bufferread, 0, BUFFER_SIZE)
and then eventually I get disconnected.

View 1 Replies405 - Method Not Allowed HttpWebRequest
Apr 2, 2012I have a problem when trying to send a POST request. The sending method looks like this:
Public Sub SendXML(ByVal file As String)
Dim reader As New StreamReader(file)
Dim data As String = reader.ReadToEnd()
[Code]....
Now looking at this I suspected that it was due to the fact that the server does not accept POST messages. But some other reading suggests that the the URI [URL] has been generated with a proxy and should be /Request so the line should read POST /Request HTTP/1.1
So what would be the common reason for this? And if it is a proxy problem, how is it sorted?
As asked below, I have created a new question for the more specific request. Changing absolute URI to relative in HTTP POST header
.net - Stream Connection Using Httpwebrequest?
Apr 3, 2012I have created a httpwebrequest connection to a streaming API after trying a tTCPClient which just never ended up working. My concern is whether my code is correct and that I am actually reading in new data and that the connection is maintained. Initially I had been reading into a buffer and just loaded everything into a file after max size, but figured it would be simpler to read a line, since each entry was being sent delimited by line feeds.
rStream = webrequest.GetResponse().GetResponseStream
rStream = New GZipStream(rStream, CompressionMode.Decompress)
If rStream.CanRead then
[code]....
It looks like I am continuously reading and not sure if I am reading redundant data here. Also another question is that if I were to use a thread to appendToFile, would that maintain the connection to the stream?

View 1 Replies.net - Will SqlConnection's Dispose Method Interfere With Connection Pool
Jul 20, 2011From my understanding, .Net will pool SqlConnection objects where the Connection String is the same by default. Will the connection still be pooled if I call the Dispose method? This question is asked under the context of an ASP .Net application that at times makes many hits to the database in a single PageLoad event. I want the connections to be pooled, but would like confirmation that Closing and Disposing of the connection once the data operation is complete does not interfere with .Net's handling of the connection pool.

Method Which Check If A Certain DSN Exists Then If It Does Extract Information And Use Information For Connection Purposes

Should i just keep looking for different code?

Once the counter reaches its maximum value, and the last picture is displayed, the counter should be reset to zero or one depending on how the first image file has been name. Also a static counter variable should be incremented in the time routine. what I have so far -- I know what I have to do; however, I just do not know how to code this properly.. Right now I have this going thru a button procedure but it needs to go through a timer.
