Build a Simple VCL Application for au PAY Market データ
How to build a simple VCL Application to view au PAY Market データ in RAD Studio using the CData ODBC Driver for au PAY Market.
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 au PAY Market, you gain access to live au PAY Market データ within RAD Studio, abstracting the data into tables, views, and stored procedures that can be used to retrieve and update au PAY Market データ. This article will walk through connecting to au PAY Market and creating a simple VCL application with the Form Designer.
Create a Connection to au PAY Market 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.
au PAY マーケットに接続するには、ShopId およびApiKey が必要です。
au PAY マーケットへのアクセスの設定
ShopId およびApiKey を取得するには、以下の手順に従ってください。
- Wow! manager サイトにログインして、「各種お申し込み」メニューの「API利用申請」に移動します。
- API利用規約に同意します。
- 「APIキーの発行はこちら」をクリックします。
- 「発行」ボタンをクリックして、API キーを生成します。
- 「接続元IPアドレスを登録」に、対象とするIP アドレスを入力します。
- 「登録」ボタンをクリックして、設定を保存します。
au PAY マーケットアカウントの認証
次の接続プロパティを設定して接続します。
- ShopId：接続先のau PAY マーケットShop ID を設定。
- ApiKey：API キーを設定。au PAY マーケットストアアカウントから取得したAPI キーです。
- UseSandbox：Sandbox 環境に接続する場合はTrue を設定。
You can then follow the steps below to use the Data Explorer to create a FireDAC connection to au PAY Market 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 au PAY Market.
Create VCL Applications with Connectivity to au PAY Market データ
Follow the procedure below to start executing queries to au PAY Market 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 au PAY Market 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 ItemCode, Price FROM Items- 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.
