Anyone here expert to use AddEventHandler or other way to solve this small problem of mine because I am a student that developing my thesis.

Situation: I have a form (frm) and a textbox (txt) on the frm and a seperate .vb file Class (cls) and a procedure (txtKeyUp) intended to handle the frm.txt.KeyUp event.

Problem: I'm not allowed to code in frm only in the cls.

Code Sample:

frm.vb

Public Class frm
    Inherits System.Windows.Forms.Form
''''''''''Generated Code
+ Windows "........."

End Class



cls.vb

Public Class cls

    Public Sub New()
    ''''''''''Implementation Code here
    'If im not mistaken must be here the required code in order to
    'Handle the frm.txt.KeyUp event.
    'something AddEventHandler here.
    End Sub

    Public Sub txtKeyUp()
    ''''''''''Implementation Code here
    End Sub
End Class

Hi Eros,

Put this code in cls

Friend Sub txtKeyUp(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs)

End Sub

Create a cls.vb instance frm.vb

dim cls1 as new cls
in form load event add this code
        AddHandler txt.MouseDown, AddressOf cls1.txtKeyUp


You can use with out parameters also. But it is not goood practice handling a event without event and sender

Difficult can be done immediately. But Impossible will take some more time.
