Build a Simple VCL Application for Dynamics NAV Data

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

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

Creating a VCL Application for Dynamics NAV 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 Dynamics NAV from any application.

The following example populates a TDBGrid control.

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

    Dynamics NAV に接続する前に、サーバーでOData サービスを有効にしておく必要があります。OData サービスを有効にすると、本製品はサーバーで発行されるあらゆるサービスにクエリできるようになります。Url を有効なDynamics NAV サーバー組織のルート(例:http://MyServer:7048)およびServerInstance(例:DynamicsNAV71)に設定します。 もしサーバーにService Default Company がない場合は、Company(例:'CRONUS Canada, Inc.')も設定する必要があります。 マルチテナントインストールでは、Tenant にテナントId(例:'Cronus1')を指定します。

    認証するには、User およびPassword プロパティを設定して、Dynamics NAV ログインクレデンシャルまたはWindows ユーザークレデンシャルを有効にします。 AuthScheme で適切な認証メソッドを選択します。

  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.
