使用lpDesktop在其他桌面上创建CreateProcess

Question

更新

StartupInfomation结构需要ANSI字符集。

喂，

我想创建一个新桌面并在那里启动一个进程。 桌面的创建可能是有效的。 但是如果我通过设置lpDesktop变量来创建一个进程 我收到错误“应用程序无法正确初始化（0xc0000142）”。 我已经将lpDesktop设置为“Default”，“winsta0 \ Default”并将其设置为 我的其他桌面名称。不改变lpDesktop var它的开始 我的默认桌面内的进程。

    public Process CreateProcess(string path, string commandline)
    {
        if (!IsCreated) return null;

        const uint normalPriorityClass = 0x0020;

        NativeMethods.ProcessInformation processInfo;
        var startInfo = new NativeMethods.StartupInfomation();
        var pSec = new NativeMethods.SecurityAttributes();
        var tSec = new NativeMethods.SecurityAttributes();

        startInfo.cb = Marshal.SizeOf(startInfo);
        startInfo.lpDesktop = Name;
        startInfo.lpTitle = Name;

        pSec.nLength = Marshal.SizeOf(pSec);
        tSec.nLength = Marshal.SizeOf(tSec);

        var result = NativeMethods.CreateProcess(path, commandline,
                                    ref pSec, ref tSec, true, normalPriorityClass,
                                    IntPtr.Zero, null, ref startInfo, out processInfo);

        return !result ? null : Process.GetProcessById(processInfo.dwProcessId);
    }

string desktopName = "otherDesktop";
