Tutoril and sample code for Billing project
The most common type of business application using Visual Basic is Retail Billing / Invoicing Software. A Billing software are used in almost all retail business. Some examples are Grocery, medical shop, Electrical & Electronics appliance, Garments & Textiles showrooms, petrol pumps, Fruit stall, Hotels & Restaurants, etc.,Visual Basic is the excellent platform to develop these kind of projects. Due to RAD (Rapid Application Development) capabilities and short learning curve everyone with basic programming knowledge can learn Visual Basic from the scratch and develop a software in short time. In this tutorial i will teach to design & develop a Windows application that can be used in a POS (Point of Sale) Terminal.
You need Visual Studio 2005 and Ms-Access 2003 or later version. Crystal reports is bundled with Visual Studio.
Though there are many forms required for sales bill we will discuss the main form, the sales bill entry. Below i have given the screenshot for a typical sales bill
On the right had side there is bill master details. Master details are those have only one record per bill. The bill number, customer name, bill date, are saved only one time. Below is the details grid that will capture bill details like product name, quantity, rate and amount.
To add transport charges, tax there is another grid below. Below that another grid to less discounts etc., At the bottom of the form there is text box for grand total. There are four command buttons named Clear, Save, Delete and Close. The function of these buttons are obvious and self explanatory.
Now the Coding. The complete source code for the form:

When the form loads FillArchive() and ClearForm() are called. This will fill the combo box for archive. You can understand the logic. Clear form will clear all fields and make the form ready for input. Clear form also calls IntiGrid() which will Initialize the grid and set datasource. It will add combo box for selecting products. It will fetch products from Products table and UOM from UOM table. Also customer combo box data is from customer table. I have used ledgers here. So a complete accounting package is ready.
I think you have some understanding about the process. If you have any queries write to me: sundaracm@gmail.com
