Assign multiple pointers to the same OLE object

  • Last UpdatedJul 24, 2024

In a script, you can assign multiple pointers to the same OLE object by using the equals sign.

Syntax

%newpointer = %pointer

Arguments

%pointer

The name of the pointer that already references a created OLE object.

%newpointer

The name of a new pointer that should reference the same OLE object. It can contain alphanumeric characters (A-Z, 0-9) and underscore. It is case-insensitive.

Example(s)

This script creates an OLE object based on the Wscript.Shell class and creates a pointer %WS to reference it. The pointer %WS2 when set to %WS points to the same OLE object. It can be used to read from or write to properties and call methods of the same OLE object.

OLE_CreateObject(%WS,"Wscript.Shell");

%WS2=%WS;

Note: You can use message tagnames in connection with pointers. If you assign a message tagname to a pointer, it can get an ID value. You can use it to create more pointers to the same OLE object.
