如何调用CreateProcess的（）与STARTUPINFOEX从C＃和再家长孩子(How to

我需要创建一个新的过程，但这样它是另一个进程不是当前进程如再父新进程的“孩子”。

下面已经让我几乎没有.NET：如何从C＃调用CreateProcessAsUser（）与STARTUPINFOEX和.NET：如何的PInvoke UpdateProcThreadAttribute和http://winprogger.com/launching-a-non-child-process/

ProcessCreator.CreateProcess（0）开始记事本作为当前进程的孩子这是默认的行为。到现在为止还挺好。

如果传入的值是0无代码尝试启动记事本的进程ID输入值（我假设过程中存在现在）相匹配的进程的一个孩子。

不幸的是这部分不工作，并抛出以下异常：

FatalExecutionEngineError检测消息：运行时遇到一个致命错误。错误的地址是在0x69a2c7ad，上线0x1de0。错误代码为0000005。此错误可能是在CLR或在用户代码的不安全或不可校验部分中的错误。此错误的常见来源包括用于COM-互操作或PInvoke的用户编组错误，这可能会损坏叠层。

任何指针赞赏。

有你的代码的两个问题。首先， lpAttributeList的参数InitializeProcThreadAttributeList和UpdateProcThreadAttribute功能必须键入为IntPtr ，没有out修改。其次， lpValue的参数UpdateProcThreadAttribute函数必须是一个指向属性值（在你的情况， parentHandle ），而不是价值本身。下面是固定的代码。
