Hi

How can I send a user defined message to a window with additional data?

With WM_COMMAND I can send a user defined message, but without additional
data:
GetParent()->SendMessage(WM_COMMAND, GetDlgCtrlID() | MYOWNMESSAGE <<16),
(LONG)GetSafeHwnd())

With WM_NOTIFY MFC sends additional data. But how can I send my own user
defined message?

Thanks for your help!

Off the top of my head I think this is correct:

#define WM_SOME_MESSAGE WM_USER+1

// in message map of .cpp file:
ON_MESSAGE(WM_SOME_MESSAGE, OnMyMessage)

// in header file:
afx_msg LRESULT OnMyMessage(WPARAM wParam, LPARAM lParam);

// function body in .cpp file
LRESULT CMyClass::OnMyMessage(WPARAM wParam, LPARAM lParam)
{
    // do whatever processing...
   return (TRUE or FALSE);
