ON_REGISTERED_MESSAGE in C#

Question

Hi! How do i write a Eventmanager that receives registered Windows Messages? in C++ i can do this with: //}}AFX_MSG_MAP ON_REGISTERED_MESSAGE(RWM_SENSORDATA, OnReceivedData) And then declaring the Function LRESULT MyClass::OnReceivedData( UINT wParam, LONG lParam) { } Is there something Simmilar in C#? I can't find anything usefull until now. Thanks in Advance! Matthiad
