Build a Simple VCL Application for Snapchat Ads Data

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

Create a Connection to Snapchat Ads Data

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.

You will need to create an OAuth application to connect to Snapchat Ads. See the online Help documentation for an authentication guide.

Additionally, you can optionally set AccountId to provide a default Account ID (meaning it won't need to be manually provided in the WHERE clause). If the AccountId is not specified, the first account in the Accounts view is used.

You can then follow the steps below to use the Data Explorer to create a FireDAC connection to Snapchat Ads data.

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 Snapchat Ads.

Create VCL Applications with Connectivity to Snapchat Ads Data

Follow the procedure below to start executing queries to Snapchat Ads data 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 Snapchat Ads data.
   • 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 AccountId, Name FROM Campaigns WHERE Id = '123'
   • 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.
