See if this[^] can help.

由于您是通过Web浏览器帮助程序对象执行此操作的，因此应考虑使用作业对象执行此操作.它允许您对子进程设置安全限制，否则子进程将不可用.

最好的方法是使用 CreateJobObject函数 [ ^ ]，然后在浏览器中创建作业对象.然后，您可以调用 AssignProcessToJobObject函数 [ ^ ]，然后将子进程分配给作业.若要在父进程终止时关闭子进程...，您可以调用 JOBOBJECT_EXTENDED_LIMIT_INFORMATION结构 [

Hi,

Since you are doing this from a web browser helper object you should consider doing this with a job object. It allows you to put security restrictions on the child process that would otherwise not be available.

The best way to do this is to use the CreateJobObject function[^] and create a job object within the browser. Then you could call the AssignProcessToJobObject function[^] and assign the child process to the job. To have the child process close when the parent terminates... you would call the SetInformationJobObject function[^] with the JobObjectInfoClass of JobObjectBasicLimitInformation and pass a JOBOBJECT_EXTENDED_LIMIT_INFORMATION structure[^] with the LimitFlags containing the JOB_OBJECT_LIMIT_KILL_ON_JOB_CLOSE bits set. You can prevent additional processes from being created by setting the JOB_OBJECT_LIMIT_ACTIVE_PROCESS bits and populating the JOBOBJECT_BASIC_LIMIT_INFORMATION.ActiveProcessLimit member
