Definition from the API

    'VOID BuildExplicitAccessWithName(

Please add some!

Sample Code:

    ' Type of Securable Object we are operating in this sample code
    Private Const SE_FILE_OBJECT = 1&

    ' The Security Information constants required
    Private Const DACL_SECURITY_INFORMATION = 4&
    Private Const SET_ACCESS = 2&

    ' Inheritance Flags
    Private Const CONTAINER_INHERIT_ACE = &H2
    Private Const OBJECT_INHERIT_ACE = &H1

    Dim pSecDesc, pOldDACL As IntPtr
    Dim ea As EXPLICIT_ACCESS
    Dim Win32Error As Win32Exception
    Dim ret, iPerm As Integer

    ' get the Security Descriptor and DACL
    ret = GetNamedSecurityInfo(strPath, SE_FILE_OBJECT, DACL_SECURITY_INFORMATION, Nothing, Nothing, pOldDACL, Nothing, pSecDesc)
    If ret <> 0 Then
        Win32Error = New Win32Exception(ret)
        Throw New Exception(Win32Error.Message)
    End If

    ' build an explicit access structure
    BuildExplicitAccessWithName(ea, strUserName, iPerm, SET_ACCESS, CONTAINER_INHERIT_ACE Or OBJECT_INHERIT_ACE)
