Is there a way to provide AlternateView class with a stream as its content, other than its constructor?There is a ContentStream property but it's read only.I am declaring the alternateview variable in the beginning of the code but I want to initialize it with a string some time later within the code.

I don't know whether it is simple or not because i am new to programming. my requirement is : In my vb.net winform application, the filenames of the files present in "D:Project" willbe displayed in DataGridView1 control. Now I want to load these files one after another into memory stream buffer and add the headers("ID","Name","Class") to the content in the file. Then I want to save these files in "C:" with "_de" as suufix to the filename i.e.,sample_de.csv.
View 1 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):
Dim functOut As String = String.Empty
Dim wr As Alvas.Audio.IAudioReader = Nothing
Dim fs As IO.FileStream = Nothing

In our projects we use setting variables to store user setting for the applications. Moreover, with every latest version of the applications, we upgrade these variables to retain user settings.Normally, this works fine, but recently one of my end user reported an error i.e.Configuration System failed to initialize". The error is related to user.config file. Therefore we requested the user to send us his file.After received the folder, we noticed that it contains 3 files (3begfjb.newcfg,3begfjb.tmp and user. config). 3begfjb.tmp is an empty file, while 3begfjb.newcfg and user.config are identical files. We tried to open these files but the data in user.config isn't proper xml rather its unreadable formatted file.Do any you guys had experienced this sort of issue or any ideas how and what may have created these files and corrupted user.config file.
View 3 RepliesI'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)
If rStream.CanRead then

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?
