# VisualBill
An invoice management system with Full CRUD support, basic error checking, in a clean GUI package.
## Technologies Used
- Programming Langauge: VB.NET
- Microsoft SQL Server Express, chosen due to built-in compatibility with VB.NET and ease of setup.
- WinForms, chosen due to native access to Windows User Interface Common Controls which made it easy to develop desktop applications.
## Architecture & pattern
This application uses an event-driven architecture. Most of the time, the GUI application will be waiting for the user to do something (i.e. clicking on a button) before deciding on what to do.
The application use the page-controller pattern, as each page has code behind class as controller, and the code behind file depends on view. This pattern is used to separate the request handling logic from the view rendering logic. Furthermore, because the application is simple in nature, page-controller pattern is quicker to implement compared to MVC which introduces additional overhead.
## Features
### Invoice CRUD
#### Create Invoice
You can create new invoice into the system.
#### Read Invoice
You can view the invoices in the system via the invoice list.
Direct modification of dataset (i.e. through SSMS) is supported as well, simply click "Refresh Invoice List" once you are done modifying.
#### Update Invoice
You can update the invoices in the system (except for the invoice ID) by click on the details within the invoice list and making your own adjustments, then press `Enter`.
#### Delete Invoice
You can delete the invoice in the system by selecting the respective rows and pressing the `Delete` key on your keyboard.
### Error-checking
#### Duplicate Invoice ID
Duplicate invoice ID are prevented from being entered into the system.
#### Editing of Invoice ID
Direct editing of invoice ID is not permitted. The only way to do so is to delete and recreate.

3. Install MS SQL Server Management Studio v20.2 or higher
