Create a dynamic control and AddHandle WITH Values/Brackets

it seems that adding for example a button Dim myButton as New Button and then addHandler to mySub("lol", 255) is not possible.

Where mySub is Shared Sub MySub(byRef myString as string, myInteger as Integer)

So: addHandler myButton.click, addressOf mySub("lol", 255) - returns an error saying it does not work with parentheses or whatever.

I somehow see why this might not be possible, so I'm looking for a work-around on this problem.

Please help _jakeCake

Maybe you could look into using a lambda expression when you add the event. When using lambda's in VB.NET the function must return a value and does not support multi-line statements. 

Dim myButton As New Button
AddHandler myButton.Click, Function(senderObj, args) myFunc("lol", 255)

First of all the syntax for AddHandler would be:

AddHandler myButton.click, AddressOf mySub

Secondly the signature of the eventhandler procedure must match the signature of the event like so:

Private Sub myButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) 

    [...]

End Sub
