Introductory Tutorial

This tutorial will take you through the basic use of the c-treeACE SQL DBX Component - Delphi.

Like 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 c-treeACE 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 c-treeACE Database Engine.

Note our simple mainline:

procedure TForm1.btnStartClick(Sender: TObject);

begin

    Init;

    Define;

    Manage;

end;

procedure TForm1.btnDoneClick(Sender: TObject);

begin

    Done;

    Close;

end;

We suggest opening the source code with your own editor.
