只需检查您的InitInstance方法（或程序开头的任何其他位置）是否已运行具有此名称的进程。如果是这样，退出。 快速偶然发现 如何检查应用程序是否已在运行 [ ^ ]

请参阅MSDN文章如何编写支持Windows XP中快速用户切换的应用程序 [ ^ ]。 检测现有应用程序实例部分描述了如何添加代码以检查另一个实例是否已在其他用户启动时运行。 在避免应用程序的多个实例 [ ^ ]。 [/ EDIT]

I have an dialog application and I want to run that application exe once at a time i.e. when I run the exe of that application then I can not open another instance of the same application at the same time.How can ??

解决方案

Just check on your InitInstance method (or anywhere else at the start of your program) whether a process with this name is already running. If so, exit. Stumbled upon this quickly How to check if an application is already running [^]

See the MSDN article How to write an application that supports fast user switching in Windows XP[^]. The section Detect an Existing Application Instance describes how to add code to check if another instance is already running even when started by another user. [EDIT] An example with good explanations can be also found at Avoiding Multiple Instances of an Application[^]. [/EDIT]
