Control A Webcam In VB?
Nov 18, 2010I use VS2008 with Visual Basic and VB.Net. I am writing an application to save videos from a webcam, and I've found several examples that provide the basic functionality, so that I can now start and stop the webcam, and save a video as a .avi file. However my interface is still clunky: when video capture starts following
SendMessage(hWnd, WM_CAP_SEQUENCE, 0, 0)
then the window is locked and the [Stop Capture] button doesn't function, so I need to exit the window to stop capture.The documentation at Video Capture [URL] has a lot of methods that look useful, and I think that I need to link up a callback function to allow [Stop Capture] to function, but I can't figure out from this documentation how to send a WM_CAP_SET_CALLBACK_VIDEOSTREAM message to do this. I don't know how to control the formats so that I generate video files that are concise enough for web use - changing the frame rate or dimensions seems to have absolutely no effect Is there any general tutorial that will cover all of the messages in AVICAP32.dll, and show me how to implement them in VB?
Use Webcam In Program?
Oct 10, 2011I am playing around with using a webcam in a program to have the program automatically target key things within the webcams frame. I was just wondering how I would go about getting the webcam to be "used" within the program.

Nov 24, 2011Work now since some time on the task to control the microphone of a USB connected Webcam using Vb2008. The required function is simply to switch it on (full level)and switch it off (low level). I used the corresponding API's mixerline, mixerlineControl, mixerlineControlDetails etc but I could not get the microphone reacting somehow. I am able to handle all my Video usable also available code from the forums, but I could not find an applicable code I could modify for this microphone application.

May 7, 2012I am making a webcam capture program in vb.net to scan qr codes. I found some examples that show tracking a certain color, but that wont work because the qr codes have different colors. some are red, blue, purple, black, and green. I am using the touchless sdk to capture the video. How would I go about tracking the person's hand holding a 1"x1" cube? I am trying to reduce the "background noise" that the scanner has to try to read through.
View 1 RepliesTaking Pictures With Webcam Via Webcam Button?
Mar 28, 2012I have a logitech webcam that I use to take pictures of customers to submit to a server/database. Utilizing AVICAP32.DLL calls, I was able to modify my VB.NET program to take these pictures via a button in my program.
My question is, it would me more convenient to my intended users to click the webcam button, instead of clicking on the button in my program.
Is this possible to do in VB.NET? and how can I do this?
If this is not possible to do with my logitech webcam than is there a Microsoft Webcam that can do this?

View 1 RepliesProcess Of Designing A Computer Control Program To Control A HF Communications Receiver?
Jul 11, 2008I am in the process of designing a computer control program to control a HF communications receiver (radio), and have found a problem with the Serial port. I am using VB Express Edition 2008. This module of the program is supposed to take an input string from another part of the program, format it, break it into 4 bytes, and send it to the radio in hex form via COM port 1. The problem comes in when you try to enter a frequency with an 8 or a 9 in it. The 8 or 9 is usually replaced by 45, ex.-input 9900, receiver tune 4545. The exact same thing happens with 8's, input 8800 and receiver tune 4545. All other numbers other than 8 or 9 work fine. The strange part of it is that sometimes the 8's and 9's work, and work correctly. For instance, 900, 1900, 2900, 3900, 4900, 5900, 6900, and 7900 all work correctly. This led me to believe that is may only be when the 8 or 9 is in the first position, but that is not the case, it also shows up in other positions as well. All other frequencies that do not have 8 or 9 in them also work. I ran into this same problem with VB Express 2005, and worked on it for weeks before giving up and going back to VB6.0. This same module (with exception of the port open command) runs flawlessly under VB6. I have even tried importing the MSCOMM control from VB6, but it gives the same results. In de-bugging mode, all of the inputs, decimal and hex seem to be correct, so the problem must come in after you click the command button, but before it leaves the COM port.

I tried going through several threads, but couldn't find the solution I was looking for. Most of the threads involved matters (and code) too complex for my requirements, or had bugs when I reproduced the code in my editor window which I was unable to resolve due to my lack of knowledge in I/O related programming.
So far the simplest solution I could find was this one:[URl]...but after using his solution in my editor, it says 'type WIA is not defined', despite adding a reference to Microsoft Windows Image Acquisition 1.01 Type Library.

View 6 RepliesCapture Video With Webcam?
Mar 12, 2009I'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.
