问题描述
当用户正在使用Windows应用程序时，他或她同时启动另一个相同应用程序的实例。这会影响此应用程序第一个实例中的

？有没有办法禁止用户一次启动多个
申请？
谢谢。

While user is working on a windows application, at same time he or she
launches another instance of the same application. Will this affect the
global variables in the first instance of this application? How can I know
programmatically if the application is already opened when user tries to open
the second instance? Is there a way to prohibit user to launch more than one
application at one time?
Thanks.
Nina
推荐答案
嗨Nina，
每个实例都在自己的地址空间中运行，所以，没有，全局变量
不会相互干扰。

Hi Nina,
Each instance runs in its own address space, so, no, the global variables
will not interfere with each other.

我也有兴趣知道我的应用程序是否已在运行时它会启动。
启动。
如果用户打开我的应用程序所在的数据文件，这将特别有用
默认处理程序。如何将新数据文件交给我应用程序的已经运行的
实例，而不是生成我的应用程序的第二个副本？
I am also interested in knowing if my application is already running when it
starts up.
This is especially helpful if a user opens a data file to which my app is
the default handler. How can I hand the new datafile to the already running
instance of my app instead of spawning a second copy of my app?
