Developing A System Will Be Able To Detect Motion?
Dec 13, 2009
i am developing a system will be able to detect motion. up to now i am able to stream the video that is connected to my PC to VB.NET. Now i want to switch between the webcam if there is more than one webcam connected to the system. For example, the user of the system will be able to chose any webcam that is connected to the system. I am able to detect all the webcam and display those devices into a ListView. But i don't know how to change the steaming video when the user select the device. Now the video screen show the image form the default webcam.

my advance project for the final semester of software engineering is an intruder detection system which is based on motion detection. I'm using a web camera in order to capture the images sequently and let them to process for further checking to see the difference.
first of all i want to know, is this possible in vb.net (image processing)? if it is possible, please give me some ideas about this to start.i have a brief imagination about the structure but i'm not sure about the success

Is HelpStudio Lite still the tool of choice for developing a basic help system for VS 2010? The only mention of this that I can find is in the MSDN library; [url] and it references VS 2008. I just need something basic and (hopefully) free and of course it should not become obsolete anytime soon.

I'm sorry if the title is misleading but I have to develop the format for a barcode (either 1D or 2D, doesn't matter). The barcode needs to include a Purchase Order #, Bill of lading #, as well as the Line #, product ID # and quantity of each item that appears on the purchase order. Here is what I've come up with so far:

I'm looking for some advice for an application I currently developing. I'll try to keep this as brief as possible so if additional info is need just let me know.I'm developing an Winforms based event tracking system using VB.Net (VS 2008 Pro). The application collects data via serial bar code scanners and stores this data within a MS SQL Express db located on the same Windows XP Pro workstation that the application is installed on. When the application receives the formatted string of data it checks the db table and sends a reply back to the device indicating whether the data is a duplicate. I have written a PortManager class to handle the serial based devices and this functionality is working well.
I have now been asked to incorporate a new type of collection device into the system. The new device is running embedded Linux and uses TCPIP (POE) rather than serial communication. The device manufacture has assured me he can provide a string from the devices integrated scanner in the same format as my serial based devices.
If possible, I would like to utilize the current application and just add the ability to use the TCPIP devices to it. I was thinking it might be possible to just add a new class (similar to my Port Manager class) to handle the TCPIP based devices.I'm really at a loss as to the best way to approach this. I'm just not that familiar with collecting data from a Winforms application using a TCPIP based device.

I want to write a simple program, which should inform me before any files getting open (like as User account control in Windows Vista or Windows 7). I came to know that all antiviruses use this technique to detect viruses before they are affecting the system. My program must ask me as "Are you allow this file to run?" and allow it if I allow otherwise terminate the file.

I am writing an application on Windows-7 using Visual Basics 2010. I am accessing System Date with
Dim today As Integer
today = Format(Now, "dd")
Well, that works fine. But I need some indication/notification when system date changes, so that I can retrieve the new date.

I am writing a application where i need to know which games are installed on a system.I have 3 ways by which i think i can detect the games
1: Scan specific parts of registry and look for key names that match with a List of Publishers. The list is manually maintained.
2: Scan the hard disk for and do same as in step 1
3: run the program in background and check for programs in memory that use a large portion of memory(which games always do) and if they use Direct X ( Which all games do except for some) then its a game.
Now i have been thinking about it and first and second method seems to be in need of a updated database ie list of publishers to make out if a particular program is game.

We all probably know that the .NET Framework provides System.IO.File.Exists(). What I need is the best iron-clad method of detecting .File.Closed(). Which means no other processes are using the file. Here's my "tried and mostly true":

I need code to fit for an 'if then' statement based on an operating system. So let's say I am running windows XP, the program detects it, and with a simple if then' statement it opens form2, if i was running vista, it would open form1. So basically i need something like: If (WindowXP current OS) then form2.open, If (windowsvista currrent OS) then form1.openOf course, the above statement won't work because I need code to support the detection of the O.S.Note: I just need code for just these two O.S'es, also I don't care if its Windows XP SP1 2, or 3, just as long as it's an XP.

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?
