如何防止程式被重複執行

Win32 API OpenMutex ================================================================= The OpenMutex function opens an existing named mutex object. HANDLE OpenMutex( DWORD dwDesiredAccess, // access BOOL bInheritHandle, // inheritance option LPCTSTR lpName // object name ); CreateMutex =================================================================== The CreateMutex function creates or opens a named or unnamed mutex object. HANDLE CreateMutex( LPSECURITY_ATTRIBUTES lpMutexAttributes, // SD BOOL bInitialOwner, // initial owner LPCTSTR lpName // object name ); 使用方法如下: if (OpenMutex(MUTEX_ALL_ACCESS, FALSE, "自訂訊息字串")) { MessageBox(NULL, "程式己經執行了", "防止程式被重複執行功能", MB_OK); ExitProcess(0); } CreateMutex(NULL, FALSE, "自訂訊息字串"); 以上程式碼為 OhMen 個人工作室 所有 http://home.pchome.com.tw/cool/ohmen/ 時間就是金錢 << 發問前請先找找舊文章 >>
