How can i capture my console real time output and store the information in a log file?
i know that i can write in the file when i write in the console window, there's got to be a better way... how can i capture the console's output stream?
I found that Console.OpenStandardOutput is a stream, but i can't read from it
Dim r As New StreamReader(Console.OpenStandardOutput)
MsgBox(r.ReadToEnd)
r.Close()
r = Nothing

I've got a simple tool written in VB in VS 2010 that has a series of command buttons which run Windows command files and the output is sent to a Rich textbox object on the main form (the comand files take awhile to run so I wanted the output to show up in the RTB as it was produced to show progress). All worked well until I made an update to the tool so that the series of buttons are no longer hard-coded, but created dynamically from information in the app.config file. To do this, I use a button

So I am hacking together an app which listens to traffic using SharpPcap library, it reconstructs the packets from sessions using the code from TpcRcon.
Listening and reconstructing part work on their own . What I want is on each packet arrival main window gets an event so it can display the packet , and when session is reconstructed display a complete packet (I am interested in HTTP ones) . -That is where it breaks with weird symptoms: for example right now it does not stop on invoking stop listening method - the sharppcap library function hangs there forever waiting on this line of code : m_pcapThreadEvent.WaitOne();//wait for the 'stopped' signal from thread
I also had it not working and crashing in sharppcap function because I had omitted one parameter in form delegate- which makes no sense, because form delegate does not deal with packet capture at all and only reacts on "New Packet" event from my "Listener" class (which is only there to notify main form)
My app starts as module main instancing class "Listener". MainForm has it
registered as friend with event and handles even "New Packet"
Main Form:
Private Sub uiListenStart_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btListenStart.Click
aLogger.AddMessage("Started Listening")

What I am trying to do: There are three powershell scripts with different time delays as shown below.I am trying to run them asynchronously in .NET and I followed this article to implement Asyncrhonous programming. Where I am stuck:The I am not able to retrieve output after the events are invoked.The scripts are being called but then the program ends and it shows "Press any key to continue" in console windows.I don't what I am missing here.
Info: JobRequest is a class that I use to pass around information keep track of jobs.

I'm just going to throw all my code in here in case there's something wrong with a piece of the code not in the "SelectName()" sub.
Module Module1
Dim selectednames As String = ""
Dim index As Short = 0
Dim inarray As Boolean = False
[code]....
Here's an image of what it does (I suppose you can see what went wrong)13 inputs, 3 outputs expected, only 1 output given.As from what I've figured out so far, it's doing the correct amount of loops etc. It's just as soon as it starts generating the "winner" for the 2nd game key it doesn't get a string value from namesarray.Also, why is
For x = 0 To totalnames - 1
Debug.Print("namesarray(" & x & ") = " & namesarray(x))
Next
not giving me a debug output?

I want to capture Form1 window, not what is on top (what I actually see).
Dim screenshot As System.Drawing.Bitmap
Dim graph As Graphics
[code]....
It captures what is on top, for example: I have firefox on top, so in myPic.bmp will by firefox, not Form1 window. So, how can I do that when some programs are on top, it captured Form1 window?

Searching found many answers along the lines of it depends on the device driver", but I don't think that it's that way here.
I have a cheap & nasty RFID tag reader. You just have to open notepad, touch a tag to the read and its serial number appears in notepad (I have not tried it in Linux).
Anyhoo, how can I programatically capture this serial number in VB.net (20088 express)?

When I first saw Silverlight, I thought that there was a How Do I: video that demonstrated how to capture the PC screen and save it in a WMV file. Since I can't find anything like that I'm wondering if I was dreaming or it has been removed from the Net. My goal is to create a video capture Class that I can use to demonstrate my program and add the feature in my program so the user can record any issues they are having with my program and send it to me. This way I can see what issues they are having with my program.

I want to allow my user to add urls to a database, much as a user might add file names. I have a form with a label, a textbox, and a browse button. I would like the browse button to load the user's default browser and then have the final url appear in the textbox when the browser closes. I have not been able to do that, but I have come close. I have not found a way to capture the url from an arbitray browser, so I instead load ie.exe and then capture the url with an OnQuit handler. That works (even verified by the debugger) but I am unable to get the url to appear in the textbox without actually clicking in the textbox once ie closes. I would like a suggestion as to how to avoid making my user click in the textbox and, if possible, to load the user's default browser and still capture the url. Here is my code for the Browse button (IE is defined at the class level as Dim WithEvents IE As SHDocVw.InternetExplorer):
theURL = ""
IE = New SHDocVw.InternetExplorer
AddHandler IE.OnQuit, AddressOf HandleIEQuit

I have a personal project to complete and one of the smaller aspects is to capture about 10-20 seconds of video or a screenshot (bitmap,jpg, etc)from a DVD. This is made even more complicated by the fact that the video files may be .VOB, .AVI or .MPG and using numerous codecs (DivX, Xvid, etc).
I have searched on google and the tutorials here, but nothing seems to fit.
Does anyone have some "simple" references, URL's, blogs, code examples that would help with my quest? (My policy is not the KISS principal, but the KISFSP ... "Keep It Simple For Stupid People")

I've been trying to play with DirectShow but it's getting on top of me and my question on here didn't answered so I'm thinking maybe I should go with a different approach. (DirectShow VB.net can't change recording format). <- Where as that 'works' I can't get it in the format I want it, and I don't really understand it so I'd obviousl like to go down the route of something I can get my head around.
I've googled till my fingers are raw trying to come up with an easy way to record video in my vb.net application, it doesn't have to be fancy, just a preview with a start record, stop record button, that's it.

I have a multi input capture card (Composit, s-video, ...) and I developed a program with avicap32.dll in vb.net to connect to a webcam. But I can not use this program to connect to composite input of my capture card.It seems the capture card has a default input.
Firstly, How can I change the default input? because I want to connect to compsite input.
Secondly, is there another way to connect to my capture card?
I've been googling but I could not find any code for vb.net or C#.net. They are all in C++ and I could not traslate them to vb.net
