I have a wireless handheld Barcode terminal that is running Windows CE 4,1 .net
And i use a Program that is called Mamut Enterprise E4. I am also using VB 2008 to try to code in. how to communicate?
I am a student and I am about to make a program that will use a barcode scanner well ofcourse to scan a barcode. My problem is i don't know what library to use and what certain things i need to do so that when i am going to scan a barcode it'll be something like show it on a textbox and pull something from the database. i've actually research some. i've seen mscomm1 (not so sure about that) and POS for .net (haven't fully understood its use) were those will help me develop my program?i have a metrologic ms9520 Voyager barcode scanner. and i am going to create a program for it in vb2005.
View 1 RepliesI have an application that will run on a terminal similar to a micros terminal. The terminal is already running another vendors app that captures the users logon ID from a swipecard. I need to capture the same logon ID at the same time. This is no problem, I just hook it.
The problem is I have another app which also captures swipes. In development I am running both apps for testing. It appears that when I unhook one app it unhooks both. Rehook and all is fine. As my two apps will never be on the same terminal this is not a problem. What I am concerned about is the vendors app unhooking mine or the other way around.
I would of thought that each app would have it's own ID and that each hook would be independent. I have considered finding a way to determine if a global hook is present and then use some logic to decide on unhooking or not but can't find anything.

I chose Visual Basic 8 as a computer interface to communicate through RS232 (serial) to my microcontroller, which in turn will do its own thing to transmit data it receives from the VB GUI through wireless
I have used VB before but it's been a long time. I looked at some of the settings and it looks like it has a SerialPort com component I can use. Will it suffice for this project?Might be a simple question, but just want some tips from experienced developers.
I am using Richard L. Grier's Enhanced Serial Port dll to read input from a serial port barcode scanner I notice that the datareceived event fires only once per barcode scan, but the delegate sub fires twice per barcode scan. Once for 1st half of Barcode , 2nd for 2nd part of barcode This makes it hard to capture the full barcode so it can be passed to routines in my vb.net 2008 windows application In Richard's example 'Test Enhanced Port' program he sends it to a textbox using .selectedtext and it works fine Richards Delegate code ......................
Public Delegate Sub DisplayData(ByVal Buffer As String)
'This delegate routine marshals receive data from the receive thread context DataReceived to the Windows Form STAThread context
Private Shared Sub Display(ByVal Buffer As String)

I am trying to set a variable to the full barcode to pass to routines, instead of writing to a textbox but am not having any success
I wanted to make a vb.net version of this trick used to hide files in pictures: [URL]
In my mind I have to use an open file dialog box to do this.
I was wondering about something: is there a way to communicate with another program/process on the PC without using files? What would this look like? Is there a search term I can use to get more info? This is not a vb.net question per se, but a general software question.

View 1 Repliesi'm using Visual Basic 2008 - Office 2007 - addin for ppt.
ok i'm going to delete the other thread. i'm going to rephrase and try to explain as clearly as possible.
I need to find a code that (when i click the "Search" Button) will start searching for all available lan and wireless connections.
All the available selections will be shown in a List Box provided.
Once i find one i want to use, i can stop the search (by pressing another button "Stop" in this case) or just straight away click the one i want and press another button ("Select" in this case) and if it needs a password or WEP then it will display or it will just connect without asking.
Is there a way that VB.net can identify the encryption type of a wireless network? Just identify it, i'm not looking to do anything further than that and yet just about every search result i get from google wants to tell me how to sniff wep keys etc. Don't care, just want to know what type of encryption the network is using?

I don't want the user to deal with creating the network himself.
