virtual BOOL DoVerb( LONG nVerb, CView* pView, LPMSG lpMsg = NULL );
Return Value
Nonzero if the verb was successfully executed; otherwise 0.
Parameters
nVerb
Specifies the verb to execute. It can include one of the following:
| Value | Meaning | Symbol |
| – 0 | Primary verb | OLEIVERB_PRIMARY |
| – 1 | Secondary verb | (None) |
| – 1 | Display item for editing | OLEIVERB_SHOW |
| – 2 | Edit item in separate window | OLEIVERB_OPEN |
| – 3 | Hide item | OLEIVERB_HIDE |
The –1 value is typically an alias for another verb. If open editing is not supported, –2 has the same effect as –1. For additional values, see IOleObject::DoVerb in the OLE documentation.
pView
Pointer to the view window; this is used by the server for in-place activation. This parameter should be NULL if the container application does not allow in-place activation.
lpMsg
Pointer to the message that caused the item to be activated.
Remarks
Call DoVerb to execute the specified verb. This function calls the Activate member function to execute the verb. It also catches exceptions and displays a message box to the user if one is thrown.
If the primary verb is Edit and zero is specified in the nVerb parameter, the server application is launched to allow the OLE item to be edited. If the container application supports in-place activation, editing can be done in place. If the container does not support in-place activation (or if the Open verb is specified), the server is launched in a separate window and editing can be done there. Typically, when the user of the container application double-clicks the OLE item, the value for the primary verb in the nVerb parameter determines which action the user can take. However, if the server supports only one action, it takes that action, no matter which value is specified in the nVerb parameter.
