I've got an XMLTextWriter writing to a Stream of a WebRequest. Everything works as it should:
Dim wr As WebRequest = WebRequest.Create("https://wwwcie.ups.com/ups.app/xml/ShipAccept")

How can I intercept this XML that's being written as an XMLDocument type? I tried snagging it from the stream but that gave me a 'The stream does not support reading.' exception

I want the title attribute of the node but it gives me a message box instead saying: "System.Xml.XmlAttribute" How can I convert that or in some other way get the title attribute of the books? Another problem I will be running into is storing the books and readers in a 2D array dynamic array. How can I run through the <readers> nodes to store them in an array within the nodeTitle For Each loop?

I'm sending an http request through a proxy using tcp, and then using a streamreader to read the netstream...The streamreader is supposed read each line up to </html> , however it doesn't seem to be waiting for the packet/response to be fully received, as it always returns only the first 5-10 lines of HTML.If I add a breakpoint at the line "Using sr", and pause it there for a few seconds and then continue the execution, it will return the full HTML up to the </html> as it should.This is the part of my code which reads the response.
Dim sendbytes As Byte()
sendbytes = System.Text.Encoding.ASCII.GetBytes(ReqHeaders)
netstream = tcp.GetStream()
netstream.Write(sendbytes, 0, sendbytes.Length)

i am using visual studio 2008 using vb.net. I have opened an xml stream and am reading it using xmltextreader. So far so good. I am using the following code to parse the stream and to get an understanding of what it contains and how to use the info.

I am sending data to server via TCP IP Connection. I am using a continuous loop at the server end - that accepts new clients and while streams can be read, it reads data stream.
The data is sent from the client with 2 leading bytes of data that represent the size of the packet of data sent and type of data.
My question is: how do I retrieve the size of the data packet and then check that this amount of data has been retrieved?

i need to read a large file stream binary my code is Dim sr As New IO.FileStream(srcFile,
[Code]..
I need to read signed and unsigned 8 bit, 16 bit and 32 bit values from a file stream which may be little-endian or big-endian (it happens to be a tiff file which carries the byte order indicator at the start).I initially started by writing my own functions to read the values and was able to do so for unsigned values. e.g.
Public Function ReadUInt32() As UInt32
Dim b(4) As Byte
input.Read(b, 0, 4)
[code]....
But then I started looking at signed values and my brain broke.As an alternative, I found the IO.BinaryReader which will let me read signed values directly but doesn't seem to have any way to indicate that the data is big-endian or little-endian.Is there a nice way of handling this? Failing that, can someone tell me how to convert multiple bytes into signed values (in both byte orders)?

The '&' in the text gets escaped and gets converted to & when creating the xml file using XmlTextWriter but i dont want the conversion to take place how to prevent it?
Is there any other way besides using WriteRaw func of xmltextwriter?

I am using an XMLTextWriter to create an XML document dynamically (in VB.Net).I want empty tags to appear like this - <Tag></Tag>and not this - <Tag /> So, I am using WriteFullEndElement to end the element tag. But it is writing out the tag as -
<Tag>
</Tag>
i.e. with a newline character between the tags. The web service reading this XML rejects it due to the newline character.How do I avoid the newline, and have both the start and end tags on the same line?
I compiled some VB6 code on my Win7 x64 machine and the result .exe will not run correctly on any other machine. VB6 code is just a new template .exe file with one button, a reference to "Microsoft ActiveX Data Objects 2.6 Library" and the following code in the button press event: Dim db Set db = New ADODB.Connection It runs correctly on my machine, but no others (even other Win7 x64 machines) (Update: I found TWO other users where it runs and one of them is Jeff Atwood!, but most machines have the same problem)

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

How can I write the resulted stream to be sure I can read it again later?
I am having trouble with XMLTextWriter.WriteStartElement throwing an exception:
System.InvalidOperationException
when trying to write the second element in my XML document. This error comes back as "The Writer is closed". I have not closed it, so I am guessing it has fallen out of scope?? I have created a class to write an XML file using XMLTextWriter as an object within my class. Below is the relevant code. I have found one other post on codeguru that was never answered with the exact same issue.
Function CreateXML()...
Try
_listDocument = New XmlTextWriter(_xmlDI.FullName & "\" & currentFilename, Nothing)
CreateHeader()

I am calling these functions after instantiating a dimension from ListXML (the name of my class) with the following code:
Dim xmloutput As New ListXML
xmloutput.CreateXML()
xmloutput.AddListMember(xmloutput.ReturnWhiteList, currentItem.SenderEmailAddress, xmloutput.ReturnAddAction)
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.
I have a problem with the cryptostream, if i write the stream to a memorystream the memory that the stream used is still alocated and i have no way of unalocating it.what am i missingdoing wrong? im using-using on the streams,readers and crypto stuffs so the framework should shut them all down right? i tryed calling .close and .dispose but nothing ,in fact i moved it all over I have provided the sub that im using for the encrytion im in .net 4.5 so there is a lil async stuff but i know thats not the problem coz i moved this code out of my main app(.net 4) for testing to see if i could fix the problem.[code...]
View 12 RepliesI've reached a point where it's time to learn how to Read/Write XML files properly and I'm really confused to how we're supposed to do this. I've been reading up on using the XmlDocument, but all I'm finding is how to use it to read xml files. Right now I need to Write them, later I'll code the reading of them.
The data for the XML file comes from a couple of tables in a database too, I've got a Master/Child table (actually there's 5 child tables). I've got the data coming into DataTables and I've got the loops set up already, I'm just stuck to how do I take the Master table's row and store that data as an XmlNode then loop each of the 5 child DataTable's and add each row as a child node to the master's node.
and other non-visible characters such as whitespace in XmlDocument?I tried PreserveWhiteSpace = False and IgnoreWhiteSpace = True for XmlReaderSettings, but those didn't work.
