Scenero: Users inputs the barcode numbers into a textbox, hits the search button and is returned the description of that barcode.
Database:
Two fields: Barcode - barcodes in this field
Description - Description revalant to that barcode
Form:
Consists: Textbox(Input) - txtBarcode
Button(Process) -btnClick
Listbox(Outut) - lstDetails
Code:
Dim con As New OleDb.OleDbConnection
Dim ds As New DataSet
Dim da As OleDb.OleDbDataAdapter
[CODE]...
This is the code i got to connect to the database itself. Then i got this code for the search part
Code:
SQL = "SELECT Description FROM Table1 where Barcode = '" & txtBarcode.text & "'"
What i need to know is:
1) Is the code for the search right.
2) How to get it so the description for that barcode is displayed in a listbox.
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 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.

Return encodedString.ToString() always returns "System.Byte[]". How could I get the real UTF-8 String?
all ` should be replaced with `` right? Well, is there a function built in by vb.net that does that sort of thing already?

any thought on an efficient way to properly parse and encode xml data created from a client application. the use case is fairly simple. there will be a textbox where a generic xml structure will be presented. the xml will then be modified (in the textbox) by a user.... then, i need to validate the xml and data entered. below is an example of xml that will require processing.

I have a call to Server.URLEncode(string) from an old asp file that stores user input into a table. In this case it was a string of Chinese charters.
The actual data is :
%E8%B0%B7%E6%AD%8C%E7%9A%84%E5%89%8D%E6%99%AF%E9%BA%A6%E5%85%8B%E6%96%AF%E9%9F%A6
I rewrote the code to vb.Net and after I get the data from the table, I call
HttpContext.Current.Server.UrlDecode(string) to decode the string, add it existing mark up for an email and send it on its way.
Note that with Visual Studio i can see the HTML markup as it appears in the email, and ALL of the Chinese data is EXACTLY as I would expect it.
When the emial is received i get "???????????" characters where there should be the Chinese characters.
What I do not understand:
What Server.URLEncode actually encodes the data to. It appears to be HEX.
What the array of "?" means in outlook or any other email system that opens it, I assume it means "Hey i cant convert this stuff, so here is a question mark for kicks, good luck."
I am trying to write a function which has the ability to decode a string from utf8. I am getting the string as a response from a webserver.I am using the following line to do the decoding:
DecodeReply += System.Text.Encoding.ASCII.GetString(System.Text.Encoding.UTF8.GetBytes(temparray(i).ToString))

I am trying to build an oscilloscope; I will be using a signal coming from digital encoder going through MAX232 logic level converter to the PC via the serial port 1. The signal from the encoder is 3VDC when it is high and 0VDC when it is low, the encoder resolution is 1024 PPR, the encoder is attached to motor (1800 RPM) so the max resolution is 1843200 pulses per minute or 30720 pulses per second. I would like to make my form display the changing of the input from the serialport1 to graphical display just like the digital oscilloscope. I
I want to be able to display the signal as on and off (square wave) from the encoder and be able to display the signal as speed so when the motor is running at full speed the line be at the top of the graph and when the motor drop to 20% of its full speed the line will drop to 20% and so on.
Greetings, I'm looking for a way to encode a string into HTML that uses human-readable tags such as ê (=ê). At the moment, I am using the HttpUtility.HtmlEncode() function, but it appears to return numbered tags instead of human-readable ones. For example:
Dim str as string = HttpUtility;HtmlEncode("vente - en-tête")
'Expected: vente - en-tête
'Actually received: vente - en-tête
