I would like to acquire the images of a webcam in the background based on an event.I know there is a possibility to display the webcam stream directly in a picturebox but I want to process every single image and display them then.
The best would be if there is an event that triggers every time a webcam images is received. That event should include the image (in some kind of format).

I have been researching for a while, and now am converting my project from using forms to do transparencies to just drawing the images.

Here is what I am using: [Code] Now, I know these are not controls, but is there any possible way to make these drawn images have a click-able event fire?
View 4 RepliesI 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?

The idea is to scan a folder of images and then let the user navigate back and forth through the images using a couple of buttons.The problem is, I can only get it to return a single image, and not the whole lot. It's looks to me as though the images are getting assigned to the same index in the array. [code]

View 3 RepliesThe app i am working on is for creating theme for the iPod touch... It has to deal with LOTS of images (100's potentially) There will be the set of default images, and then the user created replacement images. I started loading all the defaults into a resx file... thinking then I could just pull them out. now that I started setting the default, this sucks! lol the app will do this, on load it will set all the images (variables) to the resx images then when a theme is loaded, it will replace the default with the user image (if the user img exists) otherwise, the default stays. Then the "screen" is drawn to show the user. so, here is just the images to build the wallpaper, dock, and status bar...

I was thinking to make an app to save images [or download images] to local hard disk. But to keep it easy, I want this app to create a small picturebox on form to show the thumbnail of downloaded image. Lets say a 5 pictureboxes has to be added with the thumbnails to show the recent downloads. A user can save the location where he wants to save the files on hard disk. A listbox or a dropdown menu will help in categorizing the images, like image1 in friends section, image2 in family section, image3 in others, etc... When the program restarts all the latest 5 thumbnails has to be loaded in pictureboxes and the directory that was chosen. Finally, a button that shows the downloaded images into original image file size one by one or a slide show. Is it possible to make such program?

View 1 RepliesI have placed several PictureBox Images of different colored dots(which represent lights) on an image of a Christmas Tree. I can make the lights randomly flash using a randomGenerator and a Select case statement. However, the code is very long. There are 67 lights on this tree and the code is 71 pages long. There has to be an easier way to do this. So far I have tried the following with two images of lights just to see if it would work and it does not work:

View 1 RepliesI 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?

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.
