VB Code To List All Webcams Or Video Capture Devices?
Jan 19, 2010
I am trying to add the ability to select a camera to my program to start with I need to list the currently installed devices in a drop down menu much like what is used in MSN's webcam selection but the only thing that I can find that comes close is
Declare Function capGetDriverDescriptionA Lib "avicap32.dll" _
(ByVal wDriverIndex As Short, _
ByVal lpszName As String, ByVal cbName As Integer, ByVal lpszVer As String, _
ByVal cbVer As Integer) As Boolean
This, even with 4 different webcams installed, returns "Windows WDM image capture"

This is my code for loading list of plugged in USB devices:
Private Sub Button5_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button5.Click
ListBox4.Items.Clear()
For Each Drive As IO.DriveInfo In IO.DriveInfo.GetDrives
[code]....
I would like when a button (lets say buttontest) is pressed it will show all files of a CD (only MP3) into ListBox5, then when buttontest2 is pressed the files in ListBox 6 will be copied from the CD to the selected USB device?

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'm currently working on a project which is basically Server-Client based. Client is standalone VB executable file and Server is web based.The program is supposed to use webcam as video capture device, stream video footages to server (on website - live feed) and allows users to manually save captured videos into their computer.Thats basically the brief description of my system. I'm starting off working with VB right now and website after I'm done with VB.I'm new to VB, this would be my 1st project on it. I've looked for available sources online and found several VB apps which lets me capture image file through my webcam. Also on MSDN forum, i found recommendations on using "DCAM Server" to stream videos on website but I'm still not sure of how to configure the settings to make it work properly, and of course, don't have a proper website for it to work with yet atm. Also realise I'll need to integrate some .dll files or activeX functions to use video capture function. I don't really know how to use these yet rite now.

VB and programming on Windows as such. Mostly c++/gcc/linux. I am trying to build this VB app that shows a streaming video from a camera and that needs to be overlaid with some custom graphics and text. I used the code published here: [URL] to get the capture part to work. It essentially uses the avicap32.dll that most of you would probably know.
My plan:
1) Capture frames using SendMessage(windowHandle, WM_CAP_EDIT_COPY, 0, 0) and then copy from clipboard.
2) Do whatever graphics/text overlay on the obtained bitmap
3) send it to some picturebox on some form that is being shown
4) Do step 1 to 3 in a loop by a spawned worker thread.
Firstly is this a reasonable way to do what I want? or is there a much more efficient/easier way to about?
Now the specific problem: From my main thread directly if I do step 1 to 3 once UIComponent.DrawImage(VideoComponent.GetBitmap()) It shows me once captured image as it should and all is good.
Just to clarify: UIComponent is an object/instance that launches the Form and owns the picturebox I want to display on. VideoComponent is an object/instance that has started the videocapture and owns the picturebox to which the video is being captured. But if I wrap the same call above in a function and launch a thread that would start with that function as its starting point, I see a blank screen. Again, for testing purpose, I am only doing step 1 through 3 just once.
The thread part of the code is like this:
Private drawthread As Thread
public sub main()
drawthread = New Thread(AddressOf threadfunc)
[CODE]........

i am trying to enumerate all IPs on my local network, but i am not having any luck. The only thing i have came up with so far is a really tedius "get my own ip and scan the subnet with pings" which surely isn't the best way? I am really only trying to get the ip of a tivo box, and i can determine it's a tivo by mac address or name. My router lists the "computer name" of the tivos as a long string of numbers with the prefix "tivo".What about broadcasting a ping packet? I could also attempt to connect with telnet to port 31339 on every one of them.

Visual Basic has a function that allows a video from a webcam to be saved as .AVI file which inherently is too large for data transfer over the internet. I would like to know if there is a function that allows the video to be saved as a .WMV, or a .FLV file so its smaller and allowed to be transfered over the net. Here is a snippet of the code i am using

I am planning to create a proprietary Windows application that will let the user capture video and audio from any other Windows application and stream it onto another computer via Internet. Capturing video is easy, I could simply let the user browse all open windows (or applications) and have the user click the prefered one. But what about audio? Is it possible in Windows to capture the audio from any application?

Does anyone know how to capture (Record) the Windows desktop and save it as a '.avi' or '.mpg' file. This functionality can be done using screen capture / presentation programs like SnagIT:[URL]..I have found many examples showing how to capture from a webcam using the 'avicap32.dll' DLL file but these dont help with this problem.
If you are asking why i dont just use SnagIT its because the interface is overly complex and building my own version would allow me to intergrate it into my existing programs.
