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 want somehow to temporarily store and compare two images capture from my web cam every 5 sec. (basically i`m going to use this as motion detection)I figure out how to perform pixel to pixel comparison but the problem is how can i store the images temporarily every 5 sec?Do i need an array?Can i avoid saving the images for the motion detection?Also is it better to convert the images into gray scale or black & white for the comparison or as they are

I have 3 images. All of them have a different background color and each have a different font used but have the same "number".Basically, I have 3 images, one with black background and another with red one. One image haver the number one "1" write in Arial and another with the same number but in comic sans and a third with number two "2"There's anyway to VB tell that are the same number inside?Maybe if I compare pixel to pixel and choose the one with less difference in pixels will do it?

I am capturing images from a webcam and I have to compare the degree of similarity between two or more images. that is... which two images are the closest match.
I know I cannot compare the pixels...so how do i go about it?
I am using Visual basic 2010 on Win7
This comparison need to be sufficiently fast. Within 2-3 seconds.
I was looking into pixel by pixel comparison. but webcam pictures as I understand do have slight changes between frames(disturbances).
I am working on recognizing hand gestures...which would in turn control a small mechanical crane...
for example a thumbs-up sign would mean a signal for crane to be switched on...and a full palm shown would mean a stop your work sign.
I plan wearing a white glove against a black background.
I also have ideas like dividing the screen into a 10x10 matrix.

I 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?

There's a game that I play, that can be modded. I create mods for it. But some people do not know how to apply the mods by themselves, and just explaining to one person takes about an hour alone.So what I'm wanting to do:Create a program that can add - remove - detect what mods are being used.We'll use'C:GameAddon' For an example target.What I'm wanting:Check Boxes that automatically check when the mod is already in the 'C:GameAddon' folder when the program starts up.and UnCheck'd if the addon isn't in there.

What I'm trying to do is simulate projectile motion in Visual Basic using Visual Studio. Essentially, something like this but without air resistance or mass.
Anyhow, the way I'm doing it is using a PictureBox and drawing the image in (of, say, a circle) every so often with a timer of interval 1 with its x and y properties being variables calculated by the formulas.
I want to know what formulas I can use to assign to x and y so that I get a movement like the one on the example. I've tried a bunch of stuff, with help from wikipedia and other sites, but can't seem to pull it off.

I have a project in WPF/VB.net 2010 that I want to create an alternate version of in Silverlight. However, it uses heavy amounts of animation, especially motion animation. Most of this animation takes advantage of storyboard double animations for either translate transforms or canvas left/top changes. Can I convert this project over to Silverlight?

I'm trying to make a way to navigate around a custom grid. Basically, I'm implementing the drag-copy feature from Excel. Right now, you click on a cell grid and can drag around the grid. Anything in the drag area gets a green tint. Once you release the mouse button, whatever was in the first cell selected is copied to all the others that are tinted. That works pretty nicely, but it works only for the cells visible on the screen. I can live with that, but decided that if you dragged over the scroll bars or the column or row headers,then the grid should scroll (if there is anywhere to scroll).
That's where the problem arose. It turns out that scrollbars don't raise the MouseMove event (at least not as far as I can see), and the MouseEnter and MouseHover events are not fired as long as the mouse button is held. Interestingly, the MouseLeave event does occur when the mouse button is held, just as the MouseMove event is occuring for all the cells. That's pretty annoying. Why do some mouse events get raised when the mouse button is down while the others don't? Also, I suppose, is there any way around this?

how to incorporate a PIC with VB.
I`m trying to find out the steps needed to achieve that, i`m i correct?
1) i need to find a PIC that is suitable for my project (to handle wireless motion sensors)?
2) I need to write the code for the PIC? (does the manufacture of the PIC provides an environment to write the assembly language?)
3) Then i need to write the vb code?
4) Finally to use a serial port to create a communication between VB and PIC. Also are their any all ready made PIC`s that can support VB code direct without the need of writing the assembly code?
