推荐答案

这个问题有两个部分，分别解决。首先回答第二部分，你需要能够在你的应用程序中设置某种进程间通信，以便接受请求来自另一个程序，当它已经运行。我建议使用管道（或共享内存或网络连接或dde）。如果你有一个'虚拟'第二个应用程序通过连接发送数据，它可能是最容易开发/实现的。由您正在运行的应用程序执行。首先运行此程序。



第二部分实际上是你的第一个问题。 Google将为您提供多种单实例应用程序机制。在应用程序的启动代码中，如果它检测到它是第二个（或后续）实例正在运行，请收集命令行信息并使用您在上面开发的代码将其转发到第一个实例。

There are 2 parts of this question, which are solved separately. To answer the second part first, you need to be able to set up some sort of inter-process communication in your app so that it will accept requests from another program when it is already running. I suggest use of a pipe (or shared memory or network connection or dde). It is probably easiest to develop/implement if you have a 'dummy' second app that sends data over the connection and is executed by your running app. Get this running first.

The second part is actually your first question. Google will give you numerous mechanisms for single instance apps. In the startup code for your app, if it detects that it is the second (or subsequent) instance running, collect the command line info and relay that to the first instance using the code you developed above.
