Overview - Creating Live Import Datasource
As the writer of the Datasource you will have to perform the following steps. Additional details follow. The term "Datasource" refers to the software that you as the user provide to move data from your application or hardware into Frontline software.
- The Datasource should read the Connection String and the Configuration from liveimport.ini, which is located in the top directory of the product installation. The Connection String is in the ‘General’ section; the Configuration String makes up the ‘Configuration’ section.
-
You may modify the Configuration String as needed; do not alter the Connection String. The format and contents of the Configuration String are covered in the next topic (See The Configuration String on page 1).
- The Datasource creates a shared-memory connection to the Frontline software by using LiveImportAPI.dll or LiveImportAPI_x64.dll.
- The Datasource reads Liveimport.ini and sends the Connection and Configuration data during initialization.
- After initialization the Datasource checks connection and sends data either as frame or a byte at a time.
- When the Datasource shuts down it releases the connection.
Note: Redistribution of an application that uses Live Import to transmit data to ComProbe Software requires LiveImportAPI.dll must be part of the distribution package. LiveImportAPI.dll must be in the same directory as the executable file
