VS 2010 Force STREAM To Read
Mar 16, 2012
I was taking code called from an event and making a function of it
Public Function asyncPostMS(prefixes() As String, ms As MemoryStream) As Stream
Dim request As WebRequest = WebRequest.Create(prefixes(0))
request.Method = "POST"
[Code]....
Now when I call this using the new function the stream is already closed. How do I pass out a stream object from a function as an already "read" object.
Or do I need to create the stream outside the function?

in an winForm app in VS2010 win 7 compiling to x86, I try to do what Alvas.Audio seems to work. See (c# ex: [URL] for reference.
Dim data() As Byte = wr.ReadData(second * i, second)
The result give me data.length()=0. I do not have any exception, I can read format from it and whatever reader I use I got this problem.EDIT : After some tests, it seems like the uncompressed file I create in the first step (in PCM format, with .wav extension) can not be recognized by the Alvas.audio library for the second step. I must miss something around Audio file markups or something alike.
Here is the code that might be the source (basically this is step 1):
Dim functOut As String = String.Empty
Dim wr As Alvas.Audio.IAudioReader = Nothing
Dim fs As IO.FileStream = Nothing
[code]....
How can I write the resulted stream to be sure I can read it again later?

Im making a desktop player for a online web radio, and for the program I wanna make it show all the stream info. Like the stream name, and such. However I dont know how to do this? I looked everywhere
The server url is setup like this "[URL]" And it has all the stream info and that there. So is there a way I can get the info from there onto like say a label? Live updates btw.

Application using ado.net
When reading data from an excel file the driver tries to detect the data type of a column based on the contents of that column.
Once it's decided on the datatype then data that is not compatible with that datatype is simply ignored and returned as Null when you read that column using ado.net
For example if most of the column contains numbers then the occasional cell containing non-numeric data is returned as null.
Is there a way to force it to always return all data as text no matter what the actual column contains. ?

I am trying to read the following xml stream but am really struggling.
<channelSnapshot xmlns="urn:betfair:games:api:v1">
<channel gameType="BLACKJACK" id="1444077" name="Exchange BlackJack">
<status>RUNNING</status>
[code]....
If the element is between a start tag and end tag such as
<status>RUNNING</status>
Then I can access the value ok. I have been using Select Case xmlnodetype but using this when the nodetype is a whitespace I can't get to the element beyond the whitespace.So that in the following line
<property name="Card 1" value="NOT AVAILABLE"/>
I cant get to anything beyond the word property.

I am trying to read a xml file (from a stream) like the one below. I need to read the xml element "recipientPhone" first,then I could read element "contents" so that I could save base64 data as file with the name coming from recipientPhone.I am using while xmlReader.read() to read the xml, is there a way that I could read element "recipientPhone" before "contents"?
xml sample:
<fax>
<clientInfo>Attachments: 2</clientInfo>
<contents><contentType>0</contentType>
<data>data1</data>

I'm trying to read in some text from a tcp stream. I know that the text has a unicode control character as the first character (0x0b) because the sending mechanism inserts it in front of all outgoing messages. I know it is an unreadable/unprintable character but would I would like to do is know how to read this character in and know that it is a 0x0b.

I am trying to use the vb.net method FileGet to populate a type library from a text file. This text file was created by a legacy application using vb6. In the vb6 code, the Put method was used to create this file by dumping the type library into the file. I'm using the same type library to parse back into using the FileGet method. The only difference is that the type library is now an interop dll. When I use the FileGet, it works for most of the files that I'm trying to read.
However, there are a few that give me the error: "Unable to read beyond the end of the stream." Does anyone know what would cause this error and how I can fix it?I've already tried to add a space and a line break at the end of the file.This did not work. I've searched for the solution but have not found anything that has worked.[code]...

I was using a break point in this method to make sure every was running right with it. Basically it is a loop to read until the end of a stream but rwNumber resets after it gets to line 50. Does objreader.read have a limit on it i am not sure.
Public Sub FormatText()
Dim filePath As String = openFileDialog1.FileName
If filePath = Nothing Then
MessageBox.Show("You have not opened a file yet")

I am attempting to read from a url into a System.IO.Stream object. I tried to use
Dim stream as Stream = New FileStream(msgURL, FileMode.Open)
but I get an error that URI formats are not supported with FileStream objects. Is there some method I can use that inherits from System.IO.Stream that is able to read from a URL?

Just starting up on VB 2008 Express (.NET). Trying to write to and read from a file. It runs without errors, but the messagebox only shows the 'OK' button, not the contents of the file as I want. I thought that maybe I have to rewind the file before reading, but AFAICS there is no 'StreamRead.Rewind' or Reset or something.

I need to read strings by stream! Is this possible? I've been searching for quite a while now, without results.So what i have is an application which gets song lyrics. The lyrics come in a string and i need to separate the string into multiple lines. Just to make that clear, lets say that im getting this text and put it into a string:
Bla bla bla..
Na nana na
And in string format = "Bla bla bla... Na nana na" but what i need to do is separate them into its original, line by line.I created an for each loop which looked for upper chars and when found, create a new line. But that didn't work out so well since the lyrics are written in proper english, using the upper "I" everywhere. So i created a new loop which ignored "I":es if they were followed by a space/blank " ". That didn't work either, it skipped some sentences.

From few days I am doing efforts to read web pages using webbrowser control in my desktop application. But it is very slower than my expectations(because I want to read lots of pages in minutes and browser control reads almost one page in 5 to 10 seconds), what I need is to read two or three tags written in web page.
So finally I decided to use something, which can give me only source code of page. I think StreamReader will help me to read it. I am not sure if it is flaxible with my purpose, or something else is there which can give me only html source code of web page.
I have written this code to read html code, but it gives error.

I am trying to make my application read data from a file. Then save the data back. However I keep getting an error which says the file is still open so cannot be edited. I also read that there is an issue with the streamreader and streamwriter do not close the program straight away. I was wondering if anyone had a way around this or any alternative ideas. Heres my code so far!

I am simply searching how to obtain errors/warning for each function/member that isnt documented. Im pretty sure I managed to do this on one of my projects, but cant find how to do it here on my workstation. I have looked into the project props, the solution props, but cant find it. I must have missed something, or maybe I could do this at home with an extension.

I need to insert an event name and event time in VB so it starts showing the countdown to that event but the event can only be during the same day ie max countdown is 23h59m59s, but I've run out of ideas. Additionally, how can I force a textbox to a certain format eg so it only accepts numbers and puts them in a pre set format. For example when I press 111111 it sets it to 11:11:11 and 6 is the max amount of numbers in the box.

I am successfuly connecting to an FTP server and have no problems with uploading / downloading files and initiating general file transfers. However, when attempting to list the directory I get a strange exception and it seemed to just start happening of its own accord.
Cannot access a disposed object. Object name: 'System.Net.Sockets.NetworkStream'. This is confusing! I am certainly not manually disposing any of the connection of stream reader objects, nor am I disposing anything else in this entire sub routine. On setting breakpoints, it seems that the array list is filled correctly but then the error fires when the status code is 226 despite me clearly specifying that the while loop should not run under these circumstances. (226 is equal to FtpStatusCode.ClosingData)
