class names (i.e. Year6 Dragons)
Students names (i.e. Sarah Jessica Parker)

Info From Scanner To Grid?

Aug 4, 2009

I want to be able to scan an item and that information be sent to a data grid. I'm able to scan a bar code and have it populate a textbox just fine. My problem is getting it from the textbox to the data grid.

The way it works, the textbox has to have focus so it can accept the input for the item being scanned. I've placed it behind the data grid and it works well like that but I was curious if anyone else knew of a better way to do this.

I'm curious if there is a way to detect if something has been scanned and if so, send it to the textbox or whereever else it can go.

Using Serial Port Scanner On Multiple Forms?

Aug 26, 2009

Currently the scanner is in a module (code below). I put it at that level because when I had it in a class and instantiated the class from the main form, no other forms except the main form would fire the DataReceived event. Well, unfortunately that's the case for the module-level as well.Here's the code for the Scanner:

Code:
Imports System.Threading
Imports System.IO.Ports

Reading Data From Serial Port For Barcode Scanner

Aug 28, 2009

I am developing a Winforms application which read barcode from barcode scanner. It's an Human wedge scanner. This will work if I placed the cursor in any textbox or notepad. But i don't want like that. Reason is that it's cordless scanner. If some want to scan some thing in store they will move around, so there is possibility of screen saver coming or system gets locked if that happens the barcodes wont capture, but the user who is scanning the barcodes won't know this thing.

So i am reading the data using serial port communication and my scanner sending the data character by character, Not a whole string. so for that I wrote the following code. Thsi code will works if i am writing to any textbox. But it is not working if want to store it in any global string. Only first character is storing in the string. The below code is working perfectly fine. but if want to save the string in Global String variable instaed of textbox the only first character in the string is storing.

Serial Port Barcode Scanner Delegate Sub Firing Twice Per Barcode Scan?

Aug 2, 2010

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)

[code]....

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

Determine If An Event Has Been Attached To Yet?

Jun 18, 2009

I have two objects - one that contains some code with will fire an event, and one that contains the handler for that event. I can't "AddHandler" in the Load of the first object,because an instance of the second object doesn't exist yet. When I raise my event, I want to check to see if a copy of object2 has been instantiated (easy to do), and if a handler has been attached to the event yet (not sure how to do this).I'm also open to another recommendation about how to do this instead. If I do my AddHandler in Object1.Load, and Object2 doesn't exist yet, then it will never handle my event, even if I create it later.Right now, in the code that fires the event, I've just resorted to doing a RemoveHandler and then an AddHandler every single time the event is raised, and then I know I'll attach when the object finally exists, but I know this is a crappy method.
