To post code replace < by [ abd > by ] !
Why are you trying to generate a TextChanged event in a Timer_Tick routine?
Try this:
Private Sub edt1_TextChanged(Old As String, New As String)
    If SubExists(mTarget, mEventName & "_" & "TextChanged") Then
         CallSub3(mTarget, mEventName & "_" & "TextChanged", Old, New)
    End If
End Sub
