CreateProcess in other desktop with lpDesktop

Update

The StartupInfomation struct need the ANSI charset.

Hallo,

I'm want to create a new desktop and start an process there. The creation of the desktop works probably. But if I create a process there by setting up the lpDesktop variable I get an error "The Application failed to initialize properly (0xc0000142)". I've already set the lpDesktop to "Default", "winsta0\Default" and to my other desktop name. Without changing the the lpDesktop var its starts the process inside my default desktop.

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

        const uint normalPriorityClass = 0x0020;

        NativeMethods.ProcessInformation processInfo;开发者_如何学JAVA
        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);
    }
