Question

Create a dynamic control and AddHandle WITH Values/Brackets

Answer 1

+1 A:

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

I'm having a hard time explaining this. Let me just write exactly my case, instead of an exampleI have made my own script. First it creates a control, let's say a panel, my code assign the background color, font and so on. The code can also make the control do some actions, for example change the color of another panel. So a script-line would look something like this:onClick:ChangeBackground-color:#ff44ff for Control-ID:myTestFormSo I try to add a handler to when the control is clicked, to run a sub ChangeBackground_Color(byRef newColor, byRef ControlID)I hope this make sense

Answer 2

A:

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)

Workes perfectly, thank you, but I'm not quite sure what you mean with "does not support multi-line statements" could you please explain this :)
