I wrote the code below and I got an error (Stream was not readble) while execute this line SR = New StreamReader(FS) why and how to fix it
the code :
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim FS As FileStream
[Code].....
I am not seeing why this won't work.
private void FNameTB_TextChanged(object sender, EventArgs e)

friend.FName = Console.ReadLine();
}

Applications in the .NET Framework can use the System.Console class to read characters from
and write characters to the console. Data from the console is read from the standard input stream,data to the console is written to the standard output stream, and error data to the console iswritten to the standard error output stream. These streams are automatically associated withthe console when the application starts and are presented as the In, Out, and Error properties, respectively.I am working with redirects and I am solving small problems one at a time. So far so good, but I lost track of the big picture here. Can someone please clarify something for me.

I have a testing platform that allows data to be posted to a real time collection system. It uses the StreamWriter object to send both HTTP and XML formats, It works fine, but there is a new request to submit uploaded files. This again works fine, unless the files are over 70k (we need to test upto 3MB). If it is over 70k, the response is the content-length too big. I have changed it so that the content-length is now set dynamically, dependant on the size of the file uploaded. However, when the StreamWriter.Close() runs, the execption The request was aborted: The request was canceled. is generated, with the InnerException Cannot close stream until all bytes are written.
From what I have found on the web, the solution is use StreamWriter.Flush(), but this code is already in place.

I am using VB.Net 2008 Express and trying to build a favorites list for a webbrowser I am working on.I get an invalid parameter error on the line that reads favicon = image.FromStream(stream).[code]the urls are stored in an array after they are taken from an xml file.I checked the url that was being used when the error occurs and it seems fine. I can even navigate to it in IE.The error I get is that "stream" is an invalid parameter, at least that is where it points to.It also shows that stream is a type System.NET.ConnectStream.Stream was originally set to System.IO.Stream.I don't know if this is a problem but it processes several urls before it gets to this one.I am wondering if this may be a permissions issue and the site is blocking the WebRequest or if it is something else.
View 12 Repliesin 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):

I'm loading blobs out of a database as a byte array and I put them in a memory stream so that I can load them into an xmldocument for parsing.However there are blobs that have multiple root nodes, this causes the parser to blow up.My solution is to just make a new root node that encompasses the whole blob. I can add onto the end just fine with a streamwriter however I can't figure out how to add onto the beginning.How can I prepend to a stream?
Update:I was having too much trouble getting this to work. The "XML" I was extracting was not proper XML and I kept on having to add more and more regexes to remove bad XML before the XmlDocument Load. I ended up using the HtmlAgilityPack to parse out my valid sections of XML and I put those inside their own xml documents.
I'm writing a VB.net application (but you can answer in C# if you want, no problem) that uses a 3rd party .NET library. In particular, one method in this library takes an IO.Stream as input (among other things) and writes the results of its processing to said stream. My problem is that the method CLOSES the stream after writing to it, so I can't read back the data that it wrote in it!To be more specific: it works, of course, if the stream is a FIeStream , since it writes the data on disk, but what if I want to read the data directly to memory? I tried using a MemoryStream, but as I said, when the method returns the stream is already closed, and I can't read back anything from it.
Imports System.IO
Public Class CloseHijackedMemoryStream

I have an application written in .NET 4.0 that needs to load in memory a native DLL (written C). At the moment I am using a P/Invoke call to LoadLibrary passing the path where the DLL is located. This works, but due to the fact that this DLL comes from a DB, I would like to know if it is possible loading it through a stream, avoiding then the necessity to store the DLL somewhere in the filesystem.

Now, I would like to overlay one more image, but this is based on a user's input from a textbox. So, to get that image, we need to take the user's input, and get the respective resource file. I do it as follows:

The overlay works correctly. So question is: Why is the overlay not working from the stream? Edit: It turns out that the overlay does actually work, but seems to overlay an enlarged image rather than the true size. Would there be any reason for this?
I 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)
