Hi, So called "named Mutexes" can be uses between processes. So in this case give the Mutex the name of the File yout are using. But be careful, i think backlashes don't work with mutexes, so you should replace backslashes with some other character. cu a.

Hi, just found some code that might help you:
HANDLE GetMutex() { CString Key = m_FileName; // Your Filename! Key.Replace('\\', '_'); HANDLE hMutex = ::OpenMutex(SYNCHRONIZE, TRUE, Key); if (!hMutex) { SECURITY_ATTRIBUTES sa; sa.nLength = sizeof(sa); sa.lpSecurityDescriptor = NULL; sa.bInheritHandle = TRUE; hMutex = ::CreateMutex(&sa, FALSE, Key); } return hMutex; }cu. a.i know nothing
