Build a Simple VCL Application for Streak Data

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

Creating a VCL Application for Streak 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 Streak from any application.

The following example populates a TDBGrid control.

1. Create a new VCL Forms Application.
2. Drop a TFDPhysStreakDriverLink and TFDConnection object onto the form.

3. Double-click the TFDConnection object. The FireDAC Connection Editor is displayed. Select "CData.Streak" in the DriverId menu and configure the connection properties.
   

   Use the following steps to generate a new API key for authenticating to Streak.

   1. Navigate to Gmail
   2. Click on the Streak dropdown to the right of the search bar
   3. Select the Integrations button. This will open a window where you can view existing integrations and create new API keys.
   4. Under the Streak API section of integrations, click the button to Create New Key.
   
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.
