In PowerBuilder, an OLEObject is your interface to an OLE server or ActiveX control. When you declare an OLEObject variable and connect to a server, you can use dot notation for that variable and send instructions to the server. The instruction might be a property whose value you want to get or set, or a function you want to call.
The general automation syntax for an OLEObject is:
oleobjectvar.serverinstruction
For OLE controls in a window, your interface to the server or ActiveX control is the control’s Object property, which has a datatype of OLEObject.
The general automation syntax for an OLE control is:
olecontrol.Object.serverinstruction
Compiling scripts that include commands to the OLE
server
When you compile scripts that apply methods to an OLEObject
(including a control’s Object property), PowerBuilder does
not check the syntax of the rest of the command, because it does
not know the server’s command set. You must ensure that
the syntax is correct to avoid errors during execution.
Make sure you give your applications a test run to ensure that your commands to the server application are correct.
A server’s command set includes properties and methods (functions and events).
OLE server applications publish the command set they support for automation. Check your server application’s documentation for information.
For custom controls and programmable OLE objects, you can see a list of properties and methods in the PowerBuilder Browser. For more information about OLE information in the Browser, see “OLE information in the Browser”.
