WithEvents ???

[Guest]

Is there any additional overhead for declaring a variable using the
WithEvents keyword even if none of the events are being handled?

 

[Scott M.]

I would imagine yes, but I can't give specifics.

 

[NoOne]

Is it possible that its just a keyword for the visual basic compiler that
connects an object's events to some handlers? C# and Visual Basic both
compile to IL, if it did have overhead (other than compilation) it would
have to show up there.

I am pondering here but would imagine that there is no overhead because I
would again imagine that the MSIL compiler is very efficient and would
realize that there are no eventsinks for the object and hence remove and
event handling code.

A question for you is why would you declare an object withEvents if you do
not plan on using them?

Hi NoOne,

You are correct, WithEvents (in conjuction with the Handles clause) removes
the arduous task of AddHandler and RemoveHandler on all events for any
controls you make.
