Build a Simple VCL Application for Azure Active Directory データ

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

Create a Connection to Azure Active Directory データ

If you have not already, first specify connection properties in an ODBC DSN (data source name). This is the last step of the driver installation. You can use the Microsoft ODBC Data Source Administrator to create and configure ODBC DSNs.

Azure Active Directory はOAuth 認証を使用します。OAuth で認証するには、OAuthClientId、OAuthClientSecret、およびCallbackURL 接続プロパティを取得するアプリを作成する必要があります。認証手順は、ヘルプドキュメントのOAuth セクションを参照してください。

You can then follow the steps below to use the Data Explorer to create a FireDAC connection to Azure Active Directory データ.

1. In a new VCL Forms application, expand the FireDAC node in the Data Explorer.
2. Right-click the ODBC Data Source node in the Data Explorer.
3. Click Add New Connection.
4. Enter a name for the connection.
5. In the FireDAC Connection Editor that appears, set the DataSource property to the name of the ODBC DSN for Azure Active Directory.

Create VCL Applications with Connectivity to Azure Active Directory データ

Follow the procedure below to start executing queries to Azure Active Directory データ from a simple VCL application that displays the results of a query in a grid.

1. Drop a TFDConnection component onto the form and set the following properties:

   • ConnectionDefName: Select the FireDAC connection to Azure Active Directory データ.
   • Connected: Select True from the menu and, in the dialog that appears, enter your credentials.

2. Drop a TFDQuery component onto the form and set the properties below:

   • Connection: Set this property to the TFDConnection component, if this component is not already specified.

   • SQL: Click the button in the SQL property and enter a query. For example:

     SELECT id, availabilityStatus FROM Domains WHERE isVerified = TRUE
   • Active: Set this property to true.

3. Drop a TDataSource component onto the form and set the following property:

   • DataSet: In the menu for this property, select the name of the TFDQuery component.

4. Drop a TDBGrid control onto the form and set the following property:

   • DataSource: Select the name of the TDataSource.
5. 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.
