将现有 ACE 复制到数组中:
rc = shareSec.GetSecurityDescriptor(sd)
ReDim acl(UBound(sd.DACL)+1) '+1 for the new ACL we're going to add
For i = 0 To UBound(sd.DACL)
Set acl(i) = sd.DACL(i)
Next
将新的 ACE 添加到该数组中:
Set acl(UBound(acl)) = NewACE(NewTrustee(username, domain), 2032127)
函数NewTrustee()
并NewACE()
封装了用于创建受托者和 ACE 的指令。该数字是完全控制的访问掩码。
创建一个新的安全描述符并将其分配给共享:
Set sd = wmi.Get("Win32_SecurityDescriptor").SpawnInstance_
sd.ControlFlags = flags
sd.DACL = acl
rc = shareSec.SetSecurityDescriptor(sd)
