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.

推荐答案

您是否注意到我们在扫描条形码到计算机时会打印字符串并将光标移至下一行...，
即，在文本框中打印条形码字符串后，按下一个回车键即可，您可以通过按键事件检查此情况

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
           }

       }
