如何通过内部命令使用CreateProcessWithLogonW

Question

我们有一个VB6应用程序，有时需要以提升的权限运行命令，因此我们调用CreateProcessWithLogonW函数，因此我们可以这样做，而无需用户输入凭据。目前，我们使用xcopy进行此操作，并且可以正常工作。现在，我正在尝试实现删除功能，但返回代码LastDLLError = 2（我相信这意味着找不到文件）的返回值为0。因此，我认为此行为的原因是由于xcopy是外部命令，而del是内部命令。有什么方法可以将del与CreateProcessWithLogonW一起使用？如果不是，是否有任何其他替代方式可以使用“内置”的del命令（即不使用批处理脚本，必须存储在某个地方的自定义程序等）？

Public Declare Function CreateProcessWithLogon Lib "Advapi32" Alias "CreateProcessWithLogonW" _

    StartInfo.cb = LenB(StartInfo)
    StartInfo.dwFlags = &H1     'new console window
    StartInfo.wShowWindow = &H0 'hide the new console window

    'Run command
    lngReturnValue = CreateProcessWithLogon(StrPtr(strUserName), StrPtr(strDomain), StrPtr(strPassword), &H2&, StrPtr(vbNullString), StrPtr(strCommand), _

    If lngReturnValue = 0 Then
        RaiseErr errExternalProgram_ProgramErredOut, "CreateProcessWithLogonW function failed." & vbCrLf & _
