Capture Barcode From Background In VB 2010?
Jun 6, 2011I'm looking to create a program which will run in the background, but will capture any data input by a barcode scanner. Since barcode scanners work more or less as keyboards (I'm not familiar with the specifics of the implementation, but my reading and their behaviour suggests this) my plan was to simply capture all keypresses and look for a distinctive pattern (sequence of numbers entered in improbably fast succession).
I'm a little concerned, however, about the fact that this will require holding up keypresses until I confirm a match. The holdup will probably be barely noticable, but it's still not ideal. My quesetion is: is there any better means of implementation than simple key and pattern detection, for example detecting that the keypresses originate from a barcode scanner?

Error In Serial Port Data Capture Program In Visual Studios 2010?
Apr 11, 2012I'm trying to make a rs232 serial data logging program, that accepts a 12 bit hex RFID tagID from an RFID module. My end objective is to save this RFID tagID into a database and assigned to a person for a personnel management system.I had to use button3 to add the value of the variable 'msg' into textbox1 because I was getting the following error "Cross-thread operation not valid: Control 'TextBox1' accessed from a thread other than the thread it was created on". It is a temporary workaround.When I do press button3, I get the incomplete hex number, instead of "4C00A2C82A0C", I get "A2C82A0C", and sometimes I get random digits like 1,A,C etc etc.
Public Sub OpenPort()

If SerialPort1.IsOpen Then

Packet Capture And Threading, Capture Library Waits For "thread Stop"
Apr 5, 2009So 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")

Capture The PC Screen
Oct 13, 2010When 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.
View 2 RepliesCapture Url When IE Exits?
Aug 5, 2010I 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

View 1 RepliesHow To Capture A Frame From A DVD
Aug 1, 2010I 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")

An 'easy' Way To Capture Video?
Apr 15, 2012I'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.

Cannot Connect To Capture Card
Jun 22, 2010I 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
