I am creating a stock management application for a jewelry shop. I have completed adding and selling of stock without barcodes. Now they want me to integrate it with barcodes.
When I add stock, a barcode should be printed like so:
And the entry which I am making is like so:
And as soon as I hit the save button the stock will be added to the database. How can I write code for the barcode to get it print?
The code which I am using till now is here:
public partial class FrmAddNewItem : Form
{
public static bool isEditMode = false;
private void btnReset_Click(object sender, EventArgs e)
{
addComboItems();
Utility.resetForm(groupBox1);
isEditMode = false;
btnStartInvoice.Enabled = true;
btnSave.Text = "Save";
generateBarCode();
}
private void generateBarCode()
{
Random random = new Random();
String barCode = random.Next(1000000000, int.MaxValue).ToString();
String strCmd = "select itemCode from tblItemDetail where itemCode='" + barCode + "'";
while (DBUtil.isRecordExist(strCmd))
{
barCode = random.Next(1000000000, int.MaxValue).ToString();
strCmd = "select itemCode from tblItemDetail where itemCode='" + barCode + "'";
}
txtBarCode.Text = barCode;
lblBarCode.Text = barCode;
lblBarCode.Font = new Font("Barcode Font", 48);
}

I just need help to get a printout of that barcode, so that they can stick this barcode on their items. They will have barcode printer.
