It sounds like you're looking for a useful piece of VB.NET source code related to billing software — possibly a complete project or a key module (e.g., invoice generation, product billing, GST/tax calculation, receipt printing).

Since I can’t directly send files, here’s a practical VB.NET billing software snippet you can use or expand.
This example covers:

• Adding items to a bill
• Calculating subtotal, tax, and total
• Displaying bill in a DataGridView and ListView

🧾 VB.NET Billing Software Source Code Review: Nostalgia Meets Practicality

If you’ve ever written a line of VB.NET, you know it’s like that dependable old cash register in a corner store: not flashy, but it just works. So when I came across a complete billing software source code written in VB.NET with a backend database (usually MS Access, SQL Server, or MySQL), I was curious — is this a goldmine for a small business or a maintenance nightmare?

Let’s break it down.

2. Login Form (Login.vb)

Secure authentication using salt-hash (simplified here for demo).

Public Class LoginForm
    Private Sub btnLogin_Click(sender As Object, e As EventArgs) Handles btnLogin.Click
        Dim username As String = txtUsername.Text
        Dim password As String = txtPassword.Text
        Dim query As String = $"SELECT Role FROM tbl_Users WHERE Username='username' AND Password='password'"
        Dim dt As DataTable = ExecuteQuery(query)
    If dt.Rows.Count > 0 Then
        Dim role As String = dt.Rows(0)("Role").ToString()
        Dim mainForm As New MainDashboard(role, username)
        mainForm.Show()
        Me.Hide()
    Else
        MessageBox.Show("Invalid credentials!")
    End If
End Sub

End Class

Security Note: Never store plain passwords in production. Use SHA256 hashing.
