Question
How can I send Ctrl+C/Escape to the AutoCAD command line with SendMessage()?
Answer
Using the COPYDATASTRUCT structure you have to send the 0x1B (=27) character,
which corresponds to the ESCAPE key, to the command line.
// Canceling all the running commands
CString cmd (_T("\x1B\x1B")) ;
COPYDATASTRUCT cmdMsg ;
cmdMsg.dwData =(DWORD)1 ;
cmdMsg.cbData =(DWORD)_tcslen(cmd) + 1 ;
cmdMsg.lpData =cmd.GetBuffer (cmd.GetLength () + 1) ;
::SendMessage (acedGetAcadFrame ()->m_hWnd, WM_COPYDATA, NULL, (LPARAM)&cmdMsg)
;

SendMessage, cmdMsg
