[dynamic_sysop]

you can use sendmessage , but modified for your .net requirements , you must specify the type of lparam depending on circumstances , eg : if its a string ByVal lParam As String

Public Declare Function SendMessage Lib "user32.dll" Alias "SendMessageA" (ByVal hwnd As IntPtr, ByVal wMsg As Integer, ByVal wParam As Integer, ByRef lParam As String) As Integer

SendMessage( Control.Handle goes here , message to send here , 0 , " lparam ( eg: string ) here )
