我正在为一家珠宝店创建一个库存管理应用程序。我已经完成了没有条形码的库存的添加和销售。现在他们希望我将其与条形码集成。
当我添加库存时，应该像这样打印条形码：
我正在做的条目是这样的：
一旦我点击保存按钮，股票就会被添加到数据库中。如何为条形码编写代码以打印？
我现在使用的代码在这里：
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);
}
private void addComboItems()
{
cmboMakingType.Items.Clear();
cmboStoneRateType.Items.Clear();
cmboVendorName.Items.Clear();
cmboVendorId.Items.Clear();
cmboMakingType.Items.Add(Constants.COMBO_DEFAULT);
cmboStoneRateType.Items.Add(Constants.COMBO_DEFAULT);
cmboVendorName.Items.Add(Constants.COMBO_DEFAULT);
cmboVendorId.Items.Add(Constants.COMBO_DEFAULT);
cmboMakingType.Items.Add("Pc");
cmboMakingType.Items.Add("Gm");
cmboMakingType.Items.Add("Tot");
cmboStoneRateType.Items.Add("Ct");
cmboStoneRateType.Items.Add("Pc");
cmboStoneRateType.Items.Add("Tot");
String strCmd = "select fullName from tblMemberDetail where isActive='TRUE' and ucase(memberType)='VENDOR'";
String[] strVendorsName = DBUtil.getAllRecords(strCmd);
strCmd = "select memberId from tblMemberDetail where isActive='TRUE' and ucase(memberType)='VENDOR'";
String[] strVendorsId = DBUtil.getAllRecords(strCmd);
if (strVendorsName != null)
{
foreach (String strName in strVendorsName)
cmboVendorName.Items.Add(strName);
foreach (String strId in strVendorsId)
cmboVendorId.Items.Add(strId);
}
}
private void btnSave_Click(object sender, EventArgs e)

MessageBox.Show(strMsg, "Add New Item", MessageBoxButtons.OK, MessageBoxIcon.Exclamation);
txtItemCode.SelectAll();
txtItemCode.Focus();
return;
}
foreach (Control ctrl in groupBox1.Controls)
{
if (ctrl is TextBox && ctrl.Text == "")
ctrl.Text = "0";
}
if (cmboMakingType.SelectedIndex == 0 || cmboStoneRateType.SelectedIndex == 0)
{
strMsg = "Please select the making type and the stone rate type from the dropdown menu.";
MessageBox.Show(strMsg, "Add New Item", MessageBoxButtons.OK, MessageBoxIcon.Exclamation);
return;

doUpdate();

{

return;
}
strMsg = "New Item added successfully to the stock.";
MessageBox.Show(strMsg, "Add New Item", MessageBoxButtons.OK, MessageBoxIcon.Information);

我只需要帮助打印出那个条形码，这样他们就可以把这个条形码贴在他们的物品上。他们将有条码打印机。
