View 6 RepliesSuitable Way To Convert Any Word From Any Language To I2OF5 Barcode
Oct 26, 2008I am trying to find a suitable way to convert any word from any language to I2OF5 Barcode.In most basic terms, what I am thinking is constructing a numerical representation of a word by making use of ASCW function and I am planning to do that by a single pass through the variable that holds the word. Maybe I will use the first two digits for language ID and maybe the last two digits for storing the string length information in order to reduce the possibility of collisions that may appear.
View 3 RepliesSerial Port Barcode Scanner Delegate Sub Firing Twice Per Barcode Scan?
Aug 2, 2010I 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

Nov 27, 2009I am a student and I am about to make a program that will use a barcode scanner well ofcourse to scan a barcode.

View 1 RepliesBarcode App If String Exists Condition
Nov 24, 2010I bought acheap USB barcode reader so i could play around with some hypothetical situations. I've managed to get a good chunk of stuff worked out, and had alot of fun along the way. But i thought to myself what if the same tag is passed back along the chain due to production defects and requires remaking.
When it returns to the station to be retagged complete, how do i set the condition for it to search to see if the bar code string already exists in the database prior to either adding a new row (if if returns negative) or to append a cell in the table if the search retuens a positive result.

VS 2008 Convert A String Into A Linq Query?
May 20, 2012Is there a way to convert a string into a linq query? Searching for those words brings up tons of stuff unrelated to what I'm trying to do..For instance, this works, of course...
Dim lstMyQuery = (From item in htMyTable.values where item(0) = "Apple" Select item)
But somehow I want to do this:
Dim strQuery = "From item in htMyTable.values where item(0) = " & CHR(34) & "Apples" & CHR(34) & " Select item"
Dim lstMyQuery = (Somehow run/convert strQuery as a query)
The reason is strQuery will be different each time depending on what the user has selected earlier in the program.R if lstMyQuery is already a collection, is there a way to add to it?
Dim lstMyQuery = (From item in htMyTable.values where item(0) = "Apples" Select item)
(this obviously doesn't work, but it's basically what I want to do...)
lstMyQuery.Add(From item in htMyTable.values where item(0) = "Oranges" Select item)

VS 2008 : Convert A IP Range String To Base64String For XML Storage?
Jul 14, 2010Been a while since I last posted here. I'm busy on a new project and I need to convert a string which represents a IP range (like this: 10.0.0.0-10.0.0.254), to two Base64 strings which represents the first and second IP adress in this range definition. Like this: (start IP: CgAAAA== End IP: CgAA/g==)I've got it to work, but it such an ugly code, and I know it can be done with 2, or at max 4 lines code. But I'm not so handy with the Base64 string conversion jet. So this is where I ask for help from you guys!
Here's what I got (in goes: Apf.Iprange = "10.0.0.0-10.0.0.254")
Dim StartIp As String = Apf.IPRange.Split("-")(0)
Dim EndIp As String = Apf.IPRange.Split("-")(1)
Dim StartNumbers() As String = StartIp.Split(".")
