Are you doing this with MFC or borland?

The message is sent to your primary application window. As the doc states:

WM_USERCHANGED
A WM_USERCHANGED (0x0054) message is sent via BroadcastSystemMessage to all top-level windows, installable drivers, and VxDs when the user logs on or off and user profiles are enabled.


Under MFC you can handle this in your CMainFrame class:

In mainfrm.cpp, in the message map
 ON_MESSAGE(WM_USERCHANGED, OnUserChanged)

In mainfrm.h, before DECLARE_MESSAGE_MAP()
 afx_msg LONG OnUserChanged(WPARAM, LPARAM);

In mainfrm.cpp

LONG CMainFrm::OnUserChanged(WPARAM p1, LPARAM p2)
{
// Do something
return 0;
}

Very Good,

But I thought the ON_MESSAGE was only for user defined message like WM_USER + X.

Another proof that we can learn something every day...
Thank's again
Deesse.
