c-treeDB API for VB.Net

Introductory Tutorial

drivers\vb.nav\tutorials\Tutorial1.vb

This tutorial will take you through the basic use of the c-treeDB .NET Visual Basic Framework.

As with all other examples in the c-tree tutorial series, this tutorial simplifies the creation and use of a database into four simple steps: Initialize(), Define(), Manage(), and You’re Done() !

Tutorial #1: Introductory - Simple Single Table

We wanted to keep this program as simple as possible. This program does the following:

• Initialize() - Connects to the FairCom Database Engine.
• Define() - Defines and creates a "customer master" (custmast) table/file.
• Manage() - Adds a few rows/records; Reads the rows/records back from the database; displays the column/field content; and then deletes the rows/records.
• Done() - Disconnects from FairCom Database Engine.

Note our simple Main() function:

Imports System

Imports FairCom.CtreeDb

Module Tutorial1HL

Dim MySession As CTSession

Dim MyTable As CTTable

Dim MyRecord As CTRecord

'

' main()

'

' The main() function implements the concept of "init, define, manage

' and you're done..."

'

Sub Main()

Initialize()

Define()

Manage()

Done()

Console.WriteLine(vbCrLf + "Press <ENTER> key to exit . . .")

Console.ReadLine()

End Sub
