Hi
I am building a inventory system in which I require a barcode interface. In my program I am thinking to keep a textbox in which the cursor is focused and when the barcode is scanned the corresponding data of the code in the database should be displayed in the database in the same form.
 
How can I manage the event handling of barcode entry? I am using Visual Studio 2008.
 
Can anyone please help me?
 
Thank you.

Solution 1

Do you noticed when we scan a barcode to computer it will print the character string and move the cursor to next line...,
ie,One enter is pressing after printing barcode string in text box, You can check this from keydown event
 

private void textBox1_KeyDown(object sender, KeyEventArgs e)
       {
 
           if (e.KeyCode == Keys.Enter)
           {
               //Type your code for getting data from database
           }
 
       }

Most barcode scanners I have come across can be programmed to use a different or no suffix. All the ones in my company for example are programmed to send TAB after the scanned code.

Use TextBox2.Focus() method
