问题描述
在C#
解决方案
使用我的Opticon扫描仪阅读条形码时,我需要帮助。当使用条形码扫描仪时,我通常会要求用户只扫描条形码,我有焦点设置为文本框,然后扫描仪填写文本框,就像输入一样。
然后检查TextChanged事件是否有回车符,当它发生时,我将该文本提交为条码文本。
(基于符号/ Intermec扫描仪USB)
private void timer1_Tick( object sender,EventArgs e)
{
try
{
timer1.Stop();
string strCurrentString = textBox1.Text.Trim()。ToString();
if (strCurrentString!= )
{
this .dataGridView1.Rows.Add(textBox1.Text);
textBox1.Text = ;
}
textBox1.Focus();
}
catch (例外情况)
{
MessageBox .Show(ex.Message);
}
}
添加加载页面上的coloumn
this.dataGridView1.Columns.Add( 文字, 扫描值);

Please I need help in reading barcode using my Opticon scanner in C#
解决方案
When using Barcode Scanners I usually ask a user just to Scan the barcode, I have the focus set to a textbox, and then the scanner fills in the textbox as if it was typed.
I then check the TextChanged event for a Carriage return, and when it happens, I submit that text as the barcode text.
(Based on Symbol/Intermec Scanners USB)
private void timer1_Tick(object sender, EventArgs e) { try { timer1.Stop(); string strCurrentString = textBox1.Text.Trim().ToString(); if (strCurrentString != "") { this.dataGridView1.Rows.Add(textBox1.Text); textBox1.Text = ""; } textBox1.Focus(); } catch (Exception ex) { MessageBox.Show(ex.Message); } }
Add A coloumn on Load page this.dataGridView1.Columns.Add("Text", "Scan Value");
