Each
OLE object (except OLE controls) has a default action that it performs when you double-click
on it. For many objects, the default action is
Edit (invoking a visual editing session
for OLE 2.0 or an open editing session for linked objects and all
OLE 1.0 objects). However, there are some objects for which the
Edit action
is secondary (for example, a Media Clip object, where
Play is
the primary action). Also, many objects have more than one action
that they can perform, so they understand more than one OLE verb.
(Double-clicking on an OLE object in BUILD: DISPLAY mode does not
perform the default action, but double-clicking on the object in TESTAF
mode does.)
To access the menu of OLE verbs for an OLE object in BUILD mode, click on the object
with the right mouse button. The name of the OLE
object is located at the bottom of the pop-up menu. In the cascading menu, there is
a list of valid OLE verbs for the object. Select a verb from this menu to perform
that action. The default verb appears first in the list of verbs.
For example, a Microsoft Excel object understands Edit (for visual
editing) and Open (for open editing). A Media
Clip object understands Play and Edit.
You can also access
the list of valid verbs by clicking on the Associated
Verbs item in the Object Attributes dialog box for the object. This list just contains the names of the verbs; you cannot
initiate the verbs from
here. Again, the verb at the top of the list is the default verb.
Using SCL, you can invoke any verb that a particular OLE object understands by using
the _EXECUTE_ method with the verb as an argument. For example,
this code would invoke the verb
Play on the OLE object
mediaobj:
call notify('mediaobj', '_EXECUTE_', 'Play');You can specify multiple
verbs in a single call to _EXECUTE_. For more information about the
_EXECUTE_ method, see
_EXECUTE_ .
