Question

以下是流程调用的顺序;

服务调用流程A（这会导致流程A在本地系统帐户下运行）。
进程使用CreateProcessWithLogonW API在不同用户帐户（非管理员用户）下启动进程B（作为不同用户的登录凭据可用）。
进程B执行一些涉及调用另一个进程的活动。

直到第2步一切正常。流程B在给定的用户帐户下启动，但流程B无法执行任务，如执行批处理文件或使用CreateProcess API启动另一个流程。

以下是调用进程B的代码;

Dim si As STARTUPINFO

Dim pi As PROCESS_INFORMATION    

Dim wUser As String

Dim wDomain As String

Dim wPassword As String

Dim wCommandLine As String

Dim wCurrentDir As String

Dim wApplicaiotnName

Dim Result As Long

si.cb = Len(si)
si.lpDesktop = "WinSta0\Default"

Result = CreateProcessWithLogonW(wUser, wDomain, wPassword, _LOGON_WITH_PROFILE, 
wApplicaiotnName, "", _CREATE_UNICODE_ENVIRONMENT, 0&, wCurrentDir, si, pi)

以下代码B中使用的代码执行批处理文件;

Dim proc As PROCESS_INFORMATION

Dim start As STARTUPINFO

Dim ret As Long

Dim lpId As Long

Dim llReturn As Long

Dim RetVal As Long

With start

    .cb = Len(start)

    .lpDesktop = "WinSta0\Default"

    If Not IsMissing(WindowStyle) Then
        .dwFlags = STARTF_USESHOWWINDOW
        .wShowWindow = WindowStyle
   End If
End With

ret& = CreateProcessA(0&, pathName, 0&, 0&, 1&, _
            NORMAL_PRIORITY_CLASS, 0&, 0&, start, proc)

在另一个用户帐户下启动流程
