请问用MSScriptControl.ScriptControl如何实现asp文件里的eval

[xtxc]

<%
set h=server.createobject("ecms.globals")

response.write h.edit
x="update"
response.write eval("h").add
response.write eval("h." & x)

response.write "--------以上都正确-----------"


Set Mssc = CreateObject("MSScriptControl.ScriptControl")
Mssc.Language = "vbscript"
response.write Mssc.eval("h.add")
%>

response.write Mssc.eval("h.add")这一行出错，提示h对象错误
请问用MSScriptControl.ScriptControl如何实现asp文件里的eval，因为要写成DLL，所以必须用到MSScriptControl.ScriptControl

MSScriptControl.ScriptControl 里的代码，相当于在添加沙箱里头执行的，访问不了外边的 h

Set Mssc = CreateObject("MSScriptControl.ScriptControl")
Mssc.Language = "vbscript"
Mssc.AddObject "h", h ‘ 里面要用到的资源，主动放进去
WScript.Echo Mssc.eval("h.add")
