    <p>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.</p> <p>When I add stock, a barcode should be printed like so: <img src="https://i.stack.imgur.com/fPQI2.png" alt="enter image description here"></p> <p>And the entry which I am making is like so:</p> <p><img src="https://i.stack.imgur.com/GEgsN.png" alt="enter image description here"></p> <p>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?</p> <p>The code which I am using till now is here:</p> <pre><code> 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) { String strMsg = ""; if (txtItemCode.Text.Trim() == "") { strMsg = "Please enter the Item Code of the item to be added.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
