I am trying to make a program that would allow me to track all my customers and flights. My idea is to have a label for every seat of the plane. Then I would want it to highlight and turn green when the ticket's barcode is scanned.I think it would be cheaper to do it this way then to buy some corporate software.

View 1 RepliesI have a USB bar code scanner that is acting as an HID keyboard emulation device. I want a web page that, for testing purposes, pops up a JavaScript alert when a scan is done. I don't want to tie the event to any visible control such as a textbox so thus, I won't have focus on any control to capture the scan input. Can this be done? I'm using VS 2010 with .NET 4.0 and VB.NET with a Symbol USB bar code scanner.

I want to link textbox1.text to &Barcode& and link textbox2.text to &text1& Then just want the label printed on Zebra GX420t.
trying to create a WPF application that will allow users to print a barcode label written in ZPL that is saved to a text file on the C: drive. I am able to print the barcode with the WPF Application except it prints the same serial # without incrementing to the next one. I would like have the application:Open the test.txt file and read the last serial # that was printed. Print the next serial #. Write the last serial # it printed to the file for the next it is printed so that if I printed 1,2,3 this time, the next time it would print 4,5,6. Below is my code for the test.txt file and my VB.net code.
test.txt
^XA
^LH20,10^AE^FDBUILD LABEL^FS
[code]....
The printing process doesn't look pretty, but I was unable to get it to print with PrintDocument.Print() and I could by using a Process. I am guessing the issue is with intSN declaration not appending the serial # back to the test.txt file, instead, it adds
the barcode back to the file.
I need a software which designs barcode label and its language should be zpl and zpl2. If there is a .net code for the same.
View 3 RepliesI've got a textbox and a label. In the label, I've got the string "alberto". What I want to do is, I want the charactes I write in the textbox to highlight in the label, so, for example, when I write "al" in the textbox, the first two characters will be highlighted.
So, the real question is: how can i highlight only some characters in the label instead of the whole text?
I've got a simple textbox and as the user enters text in the textbox I display a label below with matching words (to what they are typing). When they click the DOWN or UP arrow I highlight one of the words below in the label.

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

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

View 5 RepliesWhen I exclude a block using #if #endif in VB.Net there is no visual evidence that the block has actually been excluded unless I indent the block and it does not return to the left margin. I checked the active settings for Fonts and the Excluded Code colorization is identical to that of C# and C++. However, the block is not colorized at all. VB clearly knows the block has been excluded, but I cannot figure out how to get the block highlighted as it is in C# and C++.
View 3 RepliesI would like to highlight the item in a listview that the mouse is hovering over during a drag-drop operation. I'm using a similar method for treeview that works great, but for a listview I'm having trouble. I found a C# example online, but the VB.Net equivalent did not work, unless I translated incorrectly. Here is my
VB.NET
Private Sub AddonDirList_DragOver(ByVal sender As Object, ByVal e As System.Windows.Forms.DragEventArgs) Handles AddonDirList.DragOver Dim hoveritem As ListViewItem = AddonDirList.GetItemAt(e.X, e.Y) hoveritem.Selected = True hoveritem.EnsureVisible() End Sub
When I use this code, not only does the highlight not work, but the drag-drop operation does not work at all. Rather than the typical drag-drop mouse pointer, the circle with diagonal line pointer is shown, which is what you would normally see if the listview did not have dropping enabled.
