Build a Simple VCL Application for au Wowma Data

How to build a simple VCL Application to view au Wowma data in RAD Studio using the CData FireDAC Components for au Wowma.

Embarcadero RAD Studio provides a development environment for Delphi and C++Builder applications. With the CData FireDAC Components for au Wowma, you gain access to live au Wowma data within RAD Studio, abstracting the data into tables, views, and stored procedures that can be used to both retrieve and update au Wowma data. This article will walk through connecting to au Wowma and creating a simple VCL application with the Form Designer.

Creating a VCL Application for au Wowma Data

The following instructions show how to use the Form Designer to create a simple VCL Forms application that shows the basic FireDAC objects needed to connect to au Wowma from any application.

The following example populates a TDBGrid control.

  1. Create a new VCL Forms Application.
  2. Drop a TFDPhysWowmaDriverLink and TFDConnection object onto the form.
  3. Double-click the TFDConnection object. The FireDAC Connection Editor is displayed. Select "CData.Wowma" in the DriverId menu and configure the connection properties.

    • UseSandbox:Sandbox 環境に接続する場合はTrue を設定。

  4. Drop a TFDQuery object onto the form and set the properties below:

    • Connection - Set this property to the TFDConnection object, if this object is not already specified.
    • SQL - Click the button in the SQL property and enter a query.
    • Active - Set this property to true.
  5. Drop a TDataSource object onto the form and set the following property:
