Modifying an object in an OLE control – PB Docs 126
Modifying an object in an OLE control When an OLE object is displayed in the OLE control, the user can interact with that object and the application that created it (the server).

Return values from ancestor scripts – PB Docs 126
Return values from ancestor scripts If you want to perform some processing in an event in a descendent object, but that processing depends on the return value of the ancestor event script, you can use a local variable called AncestorReturnValue that is automatically declared and assigned the return value of the ancestor event. The first…
Menus for in-place activation – PB Docs 126
Menus for in-place activation When an object is activated in place, menus for its server application are merged with the menus in your PowerBuilder application. The Menu Merge Option settings in the Menu painter let you control how the menus of the two applications are merged. The values are standard menu names, as well as…

Programmable OLE Objects – PB Docs 126
Programmable OLE Objects You do not need to place an OLE control on a window to manipulate an OLE object in a script. If the object does not need to be visible in your PowerBuilder application, you can create an OLE object independent of a control, connect to the server application, and call functions and…
Assignments among OLEControl, OLECustomControl, and OLEObject datatypes – PB Docs 126
Assignments among OLEControl, OLECustomControl, and OLEObject datatypes You cannot assign an OLE control (object type OLEControl) or ActiveX control (object type OLECustomControl) to an OLEObject. If the vendor of the control exposes a programmatic identifier (in the form vendor.application), you can specify this identifier in the ConnectToNewObject function to connect to the programmable interface without…
