Hi all,
Does anybody know why one application don't receive to message sent from  another application.

In first application I have:

const UINT nMsgID = RegisterWindowMessage( "MESSAGE" );
and
void CSendMessageView::OnButtonSend()
{
  ::SendMessage( HWND_BROADCAST, nMsgID, 0, 0 );
}


and in second:

const UINT  wm_Raport = RegisterWindowMessage( "MESSAGE" );
BEGIN_MESSAGE_MAP(CReceiveMsgView, CView)
  //{{AFX_MSG_MAP(CReceiveMsgView)
  // NOTE - the ClassWizard will add and remove mapping macros here.
  //    DO NOT EDIT what you see in these blocks of generated code!
  //}}AFX_MSG_MAP
  // Standard printing commands
  ON_COMMAND(ID_FILE_PRINT, CView::OnFilePrint)
  ON_COMMAND(ID_FILE_PRINT_DIRECT, CView::OnFilePrint)
  ON_COMMAND(ID_FILE_PRINT_PREVIEW, CView::OnFilePrintPreview)
  ON_REGISTERED_MESSAGE(wm_Raport, RaportMsg)
END_MESSAGE_MAP()
and
void CReceiveMsgView::RaportMsg()
{
  MessageBox( "RECEIVE" );
}

But when I click on button for sending message in first application second application is quiet (dont have any raport).

Please help me!

Mileta.

You must place message handler in your parent frame class, not in view since registered message is sent to main application window and as this is registered message it is not routed standard through MFC message map mechanism and doesn't reach view class.
