Visio的二次开发过程中，必定要处理很多Visio事件，事件基本上分为三类：Document事件、Applicaiton事件、AxDrawingControl事件。Document事件是每个文档创建或者打开都需要重新绑定一次的，但是Application事件不变，即不需要重新绑定，AxDrawingControl是ActiveX控件的事件响应。
在C#进行Visio的开发中，通过继承接口IVisEventProc，可以创建事件的侦听处理类，如下所示：


[ComVisible(
true
)]

public

sealed

class
EventSink2 : IVisEventProc



{





..


object
IVisEventProc.VisEventProc(
short
eventCode,
object
source,
int
eventId,

int
eventSequenceNumber,
object
subject,
object
moreInfo)



{



}


}


事件有很多类，有Application级别的，有Document级别的，有Page级别的，有Shape级别的，有Windows级别的，有Cell级别的..............，下面截取一部分事件代码看看

将事件和我们的处理函数联系起来，还需要对事件进行侦听，即AddAdvise，下面列出一段如何侦听事件的代码供参考



const

string
sink
=

""
;

Event newEvent
=

null
;


EventList applicationEvents
=
eventApplication.EventList;

EventList documentEvents
=
eventDocument.EventList;


newEvent
=
documentEvents.AddAdvise(

(
unchecked
((
short
)VisEventCodes.visEvtAdd)
+
(
short
)VisEventCodes.visEvtShape),

(IVisEventProc)
this
, sink,
"
ShapeAdd
"
);


newEvent
=
documentEvents.AddAdvise(

(
short
)VisEventCodes.visEvtDel
+
(
short
)VisEventCodes.visEvtShape,

(IVisEventProc)
this
, sink,
"
ShapeDelete
"
);


newEvent
=
documentEvents.AddAdvise(

(
short
)VisEventCodes.visEvtMod
+
(
short
)VisEventCodes.visEvtCell,

(IVisEventProc)
this
, sink,
"
CellChanged
"
);


newEvent
=
documentEvents.AddAdvise(

(
short
)VisEventCodes.visEvtCodeShapeExitTextEdit,

(IVisEventProc)
this
, sink,
"
ShapeExitedTextEdit
"
);


newEvent
=
documentEvents.AddAdvise(

(
short
)VisEventCodes.visEvtCodeQueryCancelSelDel,

(IVisEventProc)
this
, sink,
"
QueryCancelSelectionDelete
"
);


具体的使用，最好下载Visio2007 SDK进行学习，自己编写一些例子对事件进行处理
