Is there any Visual Basic SDK that will let me scan a barcode from a webcam, not an image? I have seen some that read from files, but this is not what I am looking for. If possible, I would love it if this is free!View 2 Replies View Related
I have swann webcam Mac IP cam network camera...its connected to the RJ-45 connector....I want to capture images after every 10 sec. from this and save it in to sql database..[URL]View 6 Replies View Related
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 areView 5 Replies View Related

a sensitivity text box will be placed on the program where it will compare with the computed difference of the two images. i have a program in vb6.0 that compares images like this

We are creating a Chat Application for our chatnetwork, we originally made it in VB6 works like a beauty and converting to VB.NET At the moment, it joins the channel fine, nothing wrong with this displays everything it needs to however we are in the process of showing emoticons.While we were on XP in debug mode and release mode, the emoticons showed... Once we moved the compiled version over to Vista Home and Ulitmate the emoticons would not show, we have looked and looked all over google and have not come to a conclusion, today we even moved the whole Project folder over to Vista, ran it in debug mode, and the images still wouldn't show in the RTB. Works fine in XP but not Vista? Edit/Delete MessageView 10 Replies View Related

Having been the victim of a robbery recently, I have turned my attention to web cameras used in conjunction with VB as a security system. I am well aware that there are many commercial products available to do the job but using VB has captured my imagination from a coding point of view.
There is a very basic bit of VB code that I copied from VB-HELPER which also appears in many other web sites but none really explain what the various lines of code actually do. The code is posted below:
Overreaching amateur developer that is outsourcing some of my work and doing part of it as well. I've been working on a dictionary/ thesaurus / spell check & suggestion application that I am trying to get to work on all applications within the windows environment.
I've used hooking to get key stokes and show output as the person is typing for definitions and spelling suggestions. This isn't accomplishing everything I want. Works fine for spell checking and suggestions but to click on a word that already exists or for touch screen interfaces to touch a word it doesn't work.
I was reading the Raw Input API on MSDN and thought that would work but my developer that I've hired is advising me that the RAW input's scope is only on the window that has focus and so cannot do low level hooking. I'm considering giving the effort but wanted a 2nd third fourth perspective prior to making the effort.[URL]
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?

A while back, I was graciously provided the following code which would take a screenshot of a 16 grid layout of cameras:
I designed my program for my screen resolution (1680x1050) with all forms in maximized mode. I gave the program to a freind whose laptop has a lower screen resolution than mine. Now on a lot of the forms she cannot see some of the controls because of the lower screen resolution. I added the minimize, restore down and close buttons to the forms of my program but in the restore down mode the form does not scale down to show all the controls on the form. How can I incorporate scalabilty into the forms so that all the controls will be visible in the restore down mode.View 5 Replies View Related
I am starting to develop a card game client for a CCG a friend of mine and I are creating.
I have 2 forms Client.vb and Hand.vb linked with a module.vb
In essence when the app starts up I see the client. I can then click the "Hand" button and the Hand Window is shown as well.
What my goal is is to have it so that when i hover over the card (picturebox) in my hand form that it displays a larger image of that card in the preview box (Another picture box) In Client.vb
I have everything working except when i actually mouse over the image in the hand form it creates an error:
Error:A first chance exception of type 'System.NullReferenceException' occurred in CCG 2.0.exe
The code in the mouse hover event:
F1.PictureBox2.Image = F2.PictureBox1.Image
Im Almost certain im going about this the wrong way but I cant seem to figure out any other way...
PS.I have attached an image to demonstrate what Im trying to do...
I am been working on an a small app that has a Forms.Webbrowser control that navigates to a Adobe Flash program. I have developed the app on Vista 32bit platform and have had no problems. I have sent the app to a couple of people to test out and one is using Vista 64bit and is running into a problem. I know the webbrowser control just uses the underlying base framework of IE. The problem on the 64 bit machine is when the site is navigated to it says that it needs to have Flash installed. When the user goes to Adobe's site it says they need to use a 32bit browser.
As stated on Adobe site here:[URL] the Flash player need to be in a 32 bit browser. What options do I have to be able fix this problem? Is there another control that I can use that would be the same in a 32bit platform and 64bit platform? Besides navigating to the Flash program, the browser also goes to standard web pages.
I am monitoring 12 video feeds from video cameras. Now I have more than 12 cameras, I have 134. But I will only monitor 12 cameras at a time. By Monitoring I mean, I have 12 small video screens on the form that I can see the video. The way I know which cameras are active, so I can monitor them is by a boolean value in a sql database. I run a Store Procedure in my program, and spit out the results in a XML file. I then read the XML file in a loop. This XML file will have a list of the camera names I need to monitor.
So that is for 12 video feeds. Now, I want to have a NEXT or FORWARD button on my monitor form. So when I click this it will give me the next group of cameras, 13 to 24. Now if I only have15 cameras that are active, that means the first group is 1 to 12, then the second group is 13 to 15 cameras. So I will only have 3 to monitor on the second grouping. One thought I had was to have another field in my table to mark as already as an active monitor, so when I run the SP, i will not select that row. But I need to select 12 at a time. Or I can make a number of xml files, one xml file for each grouping of 12, but I need to figure out how I can select the next group without re-selecting the first group. I have no code at the moment, I'm on my non-programming computer.
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 2 Replies View Related

The 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 2 Replies View Related

I am writing an inventory control application in which a barcode scanner will be hooked up to a laptop computer in our shipping/receiving department. What I'm wondering is, whenever a shipment comes in and the receiving clerk starts scanning the products, what exactly do I need to do in order to setup our database so that the scanner recognizes which vendor/product etc. and puts the data in the correct tables. I've written inventory control apps before but never one that incorporated the use of a barcode scanner.View 8 Replies View Related
I have downloaded the BarcodeLib.dll from[url]...
And however, my barcode scanner cannot read the hard copy barcode images that i have printed out as the following.[url]...
I have done research and some articles mention that dimension of the images will effect the readability of the barcode.
May i know what is the correct dimension to make my barcode images to be readable?
I have a barcode scanner connected to a PC that working with a c# program.now i want to distinguish between the scanner and the keyboard which one is sending data to my program.
somebody said this to me in another topic(but i can't do this yet): basically you can configure the scanner to send some characters that basically tell the computer "hi, it's me". When you see those characters in your input stream, you know the information is coming from the barcode scanner, not from something the user typed on the keyboard. Did you check the manual that came with your barcode scanner? It should have more information about this.
