May 1, 2012I need to show video in a picturebox, and when a button is pressed, capture the frame. I am making a desktop qr reader. I have the qr reader completed and working. my issue is my camera now. I would prefer something that actually works, and doesn't have severe memory leak issues, and doesn't throw an exception after it's first or second use. Would AviCap32 or Direct Show be better for what I want? Which would capture the image fastest, without causing exceptions? I tried using an open source solution called webcam_capture.dll, and it worked at first, but now I am getting an exception that I dont know how to fix. I'm assuming this goes in vbGeneral, and not the Interop and Upgrade. Most examples I have seen, use interop, so I wasn't sure. I would prefer not to use WIA. I have attempted it, and it doesn't work quite right on my computer, and this application will be distributed.

May 20, 2009I'm trying to capture an image from my webcam and save it as a .bmp file. the code i have works perfectly except for 1 issue i cant figure out no matter what I try the issue is that when i save the bitmap it only saves in 320x240 resolution even though I have set the resolution to 640x480 everywhere I could think of.
here is the (edited) code I currently have. some places I didn't know what to change so I put in 640,480 anyways to see what happened but that didnt make any difference and also didnt cause any errors so i left the changes there.

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.

Grab A Frame Capture From WebCam?
Mar 21, 2009Now I do have code already I found online, but it is just using API's like I would in VB6. Is there any .Net code to find if web cam is available, and if so, just take a pic and save to a JPG.
Note, the API methods work however I can only get it to work if I paint it onto a form or picture box. I don't want any forms or picture boxes. I just want .Net code to grab a picture with the web cam and save to file.
VS 2008 - Imagebox And Webcam Capture ?
Sep 15, 2010After a long while I started a project in VB.Net. I am making a security cam application for my own room. What I have done so far is capturing image from webcam (15 fps) to a imagebox and copying a still image from that imagebox to another in an intervall I have decided. Afterwards my code saves the image with a date and time as jpg. The code for capturing image I have found in this forum (iCam). My problem is (by the way I am an amateur programmer ) that the first imagebox (for realtime image capture) is not being showed (I dont want to see it). But if it is not active then all still images (saved as jpg) are all black. I think it is a drawing issue. I think imagebox is not being drawn (because it is not visible (actually the form is not visible)) and that is why still images are black. But I really don't know how to fix it? The class for capturing still images is very useful but only works with an imagebox.
(I really tried to understand the code. Especially the function, which copies a still image from 15 fps webcam output to a imagebox (which is used to save image as jpg file). But there are objects like: IntPtr, Hdc (getHdc, releaseHdc) and BitBlt. I really don't know anything about those objects.)
Code of iCam:
Option Explicit On
Option Strict On
Public Class iCam
#Region "Api/constants"
[CODE]...
I get realtime images with: iCam.initcam(me.picturebox1.handle.int32) and copy with: picturebox2.image= iCam.copyimage(picturebox1,New RectangleF(0, 0, Me.picturebox1.Width, Me.picturebox1.Height))
