Delegate question

[CJ Taylor]

Alright,

I probably wont be able to get this question answered, but maybe someone has
even more experience than me with delegates... Wow... that sounded
fecisious. =)

So, I'm trying to dynamically create a delegate where the parameters match
on the base level (position is the same, and there base types are the same.)
i.e.

I have an event defined as

Public event myEvent (sender as object, e as MyEventArgs)

now myEventArgs is inherited from System.EventArg s

so I have a method I'm trying to hook to through a delegate... that is
defined as

public sub mySub(sender as object, e as System.EventArg s)

Ok, so signitures don't match, which shouldn't allow a delegate to be
created because it breaks the contract (even though its inherited).

So I try creating a new delegate using System.Delegate .CreateDelegate (Type,
target, method)

so I have this as of right now

delTemp = System.Delegate .CreateDelegate (GetType(System .EventHandler),
objTarget, methInfo.Name)

evtInfo.AddEven tHandler(objHol der, delTemp)

now, this works for creating the delegate, but when I add the hander I get
an error that says "Cannot Bind to Method"

Useless.

So I tried to add in the code

evtInfo.AddEven tHandler(objHol der, ctype(delType,
gettype(evtInfo .EventHandlerTy pe)) to convert the delegate to the target
method delegate... No dice...

I get an error on the Ctype... So I'm not sure what to do besides define
events as basic System.Object, System.EventArg s and just pass the data whole
into it.. which may be the best way, but was seeing if anyone else undertood
my plight.

Thanks
