Build a Simple VCL Application for Basecamp データ
How to build a simple VCL Application to view Basecamp データ in RAD Studio using the CData ODBC Driver for Basecamp.
最終更新日：2023-06-12Embarcadero RAD Studio provides a development environment for Delphi and C++Builder applications. With the CData ODBC Driver for Basecamp, you gain access to live Basecamp データ within RAD Studio, abstracting the data into tables, views, and stored procedures that can be used to retrieve and update Basecamp データ. This article will walk through connecting to Basecamp and creating a simple VCL application with the Form Designer.
Create a Connection to Basecamp 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.
Basecamp はBasic 認証もしくはOAuth 2.0 認証を使います。Basic 認証を使用するには、Basecamp へのログインに使用するuser およびpassword が必要です。OAuth 2.0 を使用して認証するには、Basecamp にアプリを登録してOAuthClientId、OAuthClientSecret、およびCallbackURL 接続プロパティを取得する必要があります。
詳しくは、ヘルプドキュメントの「はじめに」セクションを参照してください。
さらに、AccountId 接続プロパティを設定する必要があります。これはBasecamp にログイン後にURL で確認できます。
You can then follow the steps below to use the Data Explorer to create a FireDAC connection to Basecamp データ.
- In a new VCL Forms application, expand the FireDAC node in the Data Explorer.
- Right-click the ODBC Data Source node in the Data Explorer.
- Click Add New Connection.
- Enter a name for the connection.
- In the FireDAC Connection Editor that appears, set the DataSource property to the name of the ODBC DSN for Basecamp.
Create VCL Applications with Connectivity to Basecamp データ
Follow the procedure below to start executing queries to Basecamp データ from a simple VCL application that displays the results of a query in a grid.
-
Drop a TFDConnection component onto the form and set the following properties:
- ConnectionDefName: Select the FireDAC connection to Basecamp データ.
- Connected: Select True from the menu and, in the dialog that appears, enter your credentials.
-
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 Name, DocumentsCount FROM Projects- Active: Set this property to true.
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.
-
Drop a TDBGrid control onto the form and set the following property:
- DataSource: Select the name of the TDataSource.
- 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.
