Cannot Connect To Capture Card
Jun 22, 2010
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

Is it possible to capture the raw signal from a WiFi card in the same way you can capture the signal from a sound card? (I already found code for working with a sound card and for drawing spectrograms) I'm wondering because it would make a cool radio-type project. I'd prefer a solution that integerates well with .net (VB or C#).My basic goal is to capture the ambient radio waves and build a primative "telescope" of sorts. Using the built in computer hardware is just the easiest way to accomplish this. If you have any other suggestions about how to accomplish this goal in a different way please post it as an answer also.

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")

We have a VB.Net application which works fine in our tests in different Windows XP SP3 machines. However there is one machine in which is displaying this error:
Unable to connect to any of the specified MySQL hosts
Using the mysql command, we can successfully connect to the database. We already checked for any other application or firewall that could be blocking the connection but it seems fine. We also reinstalled the system (no errors during the installation) but the MySQL error message doesn't change.
The system settings are exactly the same as in the other computers. We are using "localhost" as server in the connection string. The "hosts" file has its default values (nothing strange in there).

I am trying to connect to my remote MySql Database within Visual Studio using the compact framework.
I can successfully add a data source and preview the data within the IDE so assume that the connection is ok regarding Connection strings and remote access.
However, when I attempt to access the data using any run time control I get the following error when the table is loaded using the .fill method.
MySql.Data.MySqlClient.MySqlException was unhandled
ErrorCode=-2147467259
Message="Unable to connect to any of the specified MySQL hosts."

I have been looking for like 3 hours trying to find a dll or anything to make a simple cards game, but everything I find is oriented to C.
In this page A FreeCell game using Cards.dll - CodeProject� they talk about just what I want, but I cannot make it work in Visual Studio 2008 using Visual Basic.net, I don�t know if that has anything to do with the Vista OS I am using.
In the page I mention the author says "There are many good articles on the net on how to use the Cards dynamic link library" and I am sure the good articles are there, but my good luck has make me looping around the same nonsense results so I end up with nothing after 3 hours search.
The game I want to make is just something for a project we must do in class, how to start making a cards game fast and simple. If someone knows about a cards dll that works fine with vbnet, that someone would be my new hero.

I am trying to make a card game which can be played over the internet between users. I have already downloaded the cardGame Starter kit for Visual Basic. I plan to modify it to the game I want.I had worked with Sockets (Client-Server App) a long time ago for a small chat program for computers connected in LAN.I had the following questions:How should I start off with this Application, should I first just concentrate on making the game and then progress to trying to figure out how to make it playable over the internet?
Or should I do it the other way round?Can I attain my objective using Sockets? or do I have to use something else?Is there a tutorial available to start me off? (I Googled and "Bing"ed it but to no avail)

In my program i use a function to determine which card to play:
Private Sub hogere_kaart(ByVal klr$, ByVal splr, ByVal uitkomer)
(hogere_kaart= higher card, klr$=color, splr= player, uitkomer= the one who started the round)
In a former version of Visual Basic I did not have the problem that splr and uitkomer are not accepted: I get the message "All parameters must be explicitly typed if any of them are explicitly typed". Declaring them at the start of the code in DIm statements does not help.

I would like to be able to measure the frequency of a sine wave applied to the input of a "standard" Windows sound card system.I need to do this in near real-time (not by analyzing a wav file after the event) and I need to continuously measure every half-cycle of audio and store the results in some kind of buffer that I can read into a VB app. I have tried googling for this and it seems to be a very popular question but I have not found any really good answers. Does anyone know of a DLL that could do this? I wouldn't mind paying a reasonable sum for a commercial DLL if there is such a thing.
Another related requirement is to generate sine-waves - again this must be done in near real-time and it must be possible to change each half-cylce of the waveform. For example,I might need to generate a few half-cycles of 1500 Hz to be followed (with no break in the waveform) by half-a-cycle of 2300 Hz.
