C # How to Write attachevent in webbrowser

Source: Internet

C # webbrowser

 

For example, ihtmldocument2/3 starts to have good attributes such as onclick, onxxxxxx, and attachevent.

For example, attachevent (string strevent, object odispatch );

 

The strevent does not need to be said, but the odispatch has something to say.

 

In C ++, odispatch is an idispatch *, which does not do anything except that the invoke function handles dispid = 0.

When dispid = 0 (or equal to 0), this idispatch is triggered externally.

For example, onclick = omyclickdispatch

Cmyclickdispatch: idispatch

Invoke (....)

{

... Process The onclick message.
}

 

This is also true in C #, but it is more convenient.

 

[Comvisable (true)] // describe the idispatch Interface

Public class myclick

{

[Dispid (0)] // description of invoke processing dispid = 0

Public bool yourfunction (....)

{

}

}

 

Do not forget to add the [dispid (0)] clause. Otherwise, the default dispid is non-0, and your function will not be triggered.

 

In case of any errors, please point out, thank you!
