Rapidly Develop Front-Driven Apps with Active Query Builder

Write standard .NET to expose Front data through an SQL interface: Active Query Builder helps developers write SQL interfaces; the CData ODBC Driver for Front enables standards-based access to Front. This integration uses the Microsoft ADO.NET Provider for ODBC as a bridge between the ODBC Driver and the Active Query Builder objects to build a visual SQL composer.

Connect to Front as an ODBC Data Source

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.

Start by setting the Profile connection property to the location of the Front Profile on disk (e.g. C:\profiles\Front.apip). Next, set the ProfileSettings connection property to the connection string for Front (see below).

Front API Profile Settings

Generate an API key in Front by navigating to Settings > Plugins & API > API.

Use SQL to Interact with Front

Follow the steps below to create a WinForms visual query builder.

1. Open Active Query Builder for .NET WinForms.
2. In the new Windows Forms project go to the "File" menu and click "Connect..."
3. Under Database Connections, click "Add..."
4. Set your desired Connection Name (e.g. CData Front), set Connection Type to "ODBC" and locate your previously configured DSN in the "User/System" DSN dropdown.
5. Click "OK" to save the new connection.
6. Back in the Database Connection wizard, select the newly created connection and click "OK."
7. Click "File" > "New Query" to create a QueryBuilder

You can now build queries visually: Double-click a table in the Columns Pane Area and an entity/relationship diagram is displayed in the Query Building Area. Columns that you select in the diagram are added to the query.
