Research for the Method of Running a Single Application Instance

摘要：

To accomplish running a single instance of application through programming is a common technique in the programming work, it is also an important one. There are three common methods to accomplish running a single instance of application on Windows OS: inclu ding Looking up the caption of the main window of the application, Using thread mutex and Using Windows global atom. This paper introduces the principles of the three methods, analyzes the advantages and disadvantages of the methods. It was proved by research that the three methods have problems such as low reliability or high complexity. This paper puts forward a more simple and reliable method for such problems, that is accomplish running a single instance of application through cooperation of main window handle and thread ID.
