Build a Simple VCL Application for Evernote Data

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

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

Creating a VCL Application for Evernote 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 Evernote from any application.

The following example populates a TDBGrid control.

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

    Evernote はOAuth 認証標準を利用しています。埋め込みクレデンシャル を使用すると、接続プロパティを設定せずに接続できます。あるいは、アプリを作成してOAuthClientId、OAuthClientSecret、およびCallbackURL 接続プロパティを取得することもできます。認証方法については、OAuth 認証の使用 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.
