Use the IDD Configuration Manager (see “Configuring Controls in the IDD Configuration Manager” later in this document) to create IDC controls as part of a deployed IDD application. An IDD application can contain multiple IDC controls. Each control is given a unique name. Once created, the URL used to invoke the control is available (see “Format of the Control URL” later in this document). The URL contains parameters that specify the subject area and key to the data. Each control can be used with any subject area in the IDD application.
