Description

com_get_active_object() is similar to creating a new instance of a com object, except that it will only return an object to your script if the object is already running. OLE applications use something known as the Running Object Table to allow well-known applications to be launched only once; this function exposes the COM library function GetActiveObject() to get a handle on a running instance.

progid must be either the ProgID or CLSID for the object that you want to access (for example Word.Application). code_page acts in precisely the same way that it does for the com class.

If the requested object is running, it will be returned to your script just like any other COM object. Otherwise a com_exception will be raised. There are a variety of reasons why this function might fail, the most common being that the object is not already running. In that situation, the exception error code will be MK_E_UNAVAILABLE; you can use the getCode method of the exception object to check the exception code.
