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'm looking to make a program that would capture your whole screen, then have the picture display on the screen (simulating a frozen screen) to where the person handling the program could select a partial segment of the screen with their mouse and then save to a folder.
1. I have no idea how to go by doing this
2. My form is constantly minimized, so I have to do it without MouseDown on the form and whatnot.
How would I go by doing this?
I have been working on an image capturing tool for a long time now & I was wondering how some of those programs are able to make an aero capture of a form.I know you can capture a window if you have it's handle by using the BitBlt, but that doesn't keep the transparancy of the aero form.Let me give you an example:I did a lot of research on google but I never found anything close to something that explains how to do it.

I wrote a gui for a console app, wanted to captaure console app standarderror and standardoutput in the same time. I write a code, but it's not executed in the same time. I searched msdn and found that using DataReceivedEventHandler can be asynchronously collect the redirected StandardOutput or StandardError stream output of a proces. But I dont know how to apply it to my code. please help me. i wanted to collect standardoutput and standarderror and append it to a textbox. here is my code,As far as I understand, I have to read one stream synchronously and one asynchronously to avoid deadlock situations.But now it's not output in the same time. having delay issue for standarderror.

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 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)

View 1 Repliesim trying to get a memory stream to a textbox, the memory stream is of a .txt or .ini file that is extracted from a archive to a memory stream.Heres what ive got so far:
vb
Dim MSData As New System.IO.MemoryStream() Dim Infile As String = ComboBox10.SelectedValue 'The input archive Dim passww As String = TextBox1.Text 'Archive password Using extr As New SevenZipExtractor(Infile, passww) extr.ExtractFile("02.ini", MSData) End Using Dim sr As StreamReader = New StreamReader(MSData) Dim textSsS As String = sr.ReadToEnd() ini02.Text = textSsS
The problem is that ini02.text stays blank?

View 3 RepliesI 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"

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?
I have a Socket application that, when data is received (on the Server side) and the client is recognized, the data is passed onto its own socket and stream, and the previous socket and stream is discarded.
The data is serialized with a binary formatter before sending and deserialized on receiving the data.

is this possible to do in memory (so i can get rid of any disk IO)?:
If File.Exists("c:MyImage.png") Then
File.Delete("c:MyImage.png")
End If
[Code]....
This above code works great the first time then errors out on any successive attempts after that with the file being used by another process at the File.Delete line. The image is being generated for use as a mail attachment and i've only ever done it via a phyical file on the disk.
Basically, I need to transmit data across a network from point A to point B using a Binary Serialization System. I'm doing this to make sure that the system can't have outside listeners read the data being sent easily and to keep results secure and confidential.What is an easy way that I can encrypt, say, a generic object? Would it be easiest to serialize it to file, read the bytes in, encrypt the bytes, then store the bytes in a serialized structure and send that across the stream and reverse the process?
Private Function EncryptClass(ByVal obj As Object) As Byte()
Dim key() As Byte = {52, 15, 85, 150,
45, 12, 78, 120,

I have a user interface app that allows you to drag/drop in files - and it turns them into HttpListener request POST's to another EXECUTABLE that I have running - let's call it BACKEND1. BACKEND1 will be running on a SERVER when this gets ready for production use. Lots and lots of users running the UI - all dragging in files - all getting POST'ed to BACKEND1 - with the file included as a memory stream in the POST. BACKEND1 responds to the UI with a "sequential" file number assigned to the file centrally on the server.
On the SERVER is also running another EXECUTABLE - let's call it BACKEND2. It's job is to work with the DRAG'd in files. Both BACKEND1 and BACKEND2 sit on the same SERVER. At the moment I am writing the memory stream to DISK in BACKEND1 - and POSTing the FILENAME to BACKEND2 for it to work on. Would it be better to not write the file in BACKEND1 but instead include it in the POST to BACKEND2 - where it can be written to DISK? Is having LARGE HTTP REQUEST's a burden when sent between two EXECUTABLES on the same machine?
My primary goal is to have a really available BACKEND1 talking the the UI instances running out in the world. I'm concerned that doing the file i/o in BACKEND1 is "expensive" - and I don't care about the performance of BACKEND2 as much. just looking for opinions. I guess ultimately I'll have to bench mark this myself in a production environment to get a real answer.
The RX data from the serial port is as follows:
FE FE FA E0 00 23 45 FD
I need to truncate everything else and just have positions 5, 6 and 7 output in the hex in a TEXTBOX. See below:
452300
Instead it will put the the whole steam in the textbox and it will be in decimal format, not hex.

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...]

I was creating some complex applications in Visual Basic .NET 2008 and since they are in the testing phase right now, people manage to find an error or two every so often that causes the program to crash. The problem is that there is a tracking piece to it that logs who is currently using the programs. When a user logs in, it logs that they are currently logged in, and if the form close event is fired, the log is deleted to show that they have closed it.
Now my problem comes whenever the form crashes from an error since it won't trigger the close event and therefore makes the log become inaccurate. My question is if it is possible to capture any error that the form would have in the form of an event?
