Build a Simple VCL Application for QuickBooks Data

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

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

Creating a VCL Application for QuickBooks 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 QuickBooks from any application.

The following example populates a TDBGrid control.

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

    ローカルQuickBooks インスタンスへの接続には接続プロパティ入力はは不要です。

    ドライバーは、Remote Connector 経由でQuickBooks にリクエストを作成します。Remote Connector はQuickBooks と同じマシン上で動作し、軽量の組み込みWeb サーバーを介して接続を受け入れます。サーバーはSSL/TLS をサポートし、ユーザーにリモートマシンからのセキュアな接続を可能にします。

    初めて接続するときは、本製品 をQuickBooks で認証する必要があります。詳しくは、Using the Remote Connector ガイドを参照してください。

  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:

    • DataSet - In the menu for this property, select the name of the TFDQuery object.
  6. Drop a TDBGrid control onto the form and set the following property:

    • DataSource - Select the name of the TDataSource.
  7. Drop a TFDGUIxWaitCursor onto the form. This is required to avoid a run-time error.

You now have an executable application that displays the results of the SQL Query set in the TFDQuery object.
