A PowerBuilder application can act as a client to a COM server. The server can be built using PowerBuilder or any other COM-compliant application development tool. To access a method associated with a component on the COM server, the PowerBuilder client connects to the server using its programmatic identifier (ProgID) or its class ID (CLSID). If the COM server is running in MTS, the server's client deployment file must be installed on the client. If the COM server is not running in MTS, it must be registered on the client.
PowerBuilder includes wizards you can use to build COM and MTS clients:
- Template Application wizard Helps you create a client application
- Connection Object wizard Creates a connection service object with built-in code required to connect to the COM server
