As mentioned by pilif and Bob, you need to use CreateProcess.
正如 pilif 和 Bob 所提到的，您需要使用CreateProcess.
If you want code that wraps it all up for you, I do have a class for this exact issue at:

I use to found the problem like you.
我曾经像你一样发现了这个问题。
Suppose, You want to capture the output from STDOUT that it's generated by dircommand and save the captured into out.txt.
假设，您想从dir命令生成的 STDOUT 中捕获输出并将捕获的内容保存到out.txt 中。
Use text editor and type dir > out.txtand save it with mybat.bat(*.bat, don't *.txt)
In your c/c++ program, type WinExec("mybat.bat", SW_HIDE);and run your application.
Open the out.txtyou will see the name of folders and files in current directory.
使用文本编辑器输入dir > out.txt并用mybat.bat(*.bat, 不要 *.txt) 保存
在你的 c/c++ 程序中，输入WinExec("mybat.bat", SW_HIDE); 并运行您的应用程序。
打开out.txt，您将看到当前目录中的文件夹和文件的名称。
Also, you can run any executable files (*.exe) at the same way as follow.
此外，您可以按照以下相同的方式运行任何可执行文件 (*.exe)。
xxx.exe > out.txt
xxx.exe > 输出.txt
I hope it can be helps you. Sorry, my English really not good.
我希望它可以帮助你。对不起，我的英语真的不好。

That's not possible. ShellExecute(Ex) basically executes the application in the context of the shell - so you are basically doing what explorer does.
那是不可能的。ShellExecute( Ex) 基本上是在 shell 的上下文中执行应用程序 - 所以你基本上是在做资源管理器所做的。
Capturing STDIN and STDOUT is something the shell generally doesn't do, you you will have to go the CreateProcessroute (which, after all, is what ShellExecuteeventually calls if the file to execute is a program and the verb is 'open').
捕获 STDIN 和 STDOUT 是 shell 通常不会做的事情，你将不得不走这CreateProcess条路线（毕竟，ShellExecute如果要执行的文件是一个程序并且动词是“打开” ，最终会调用它）。
