function Base64EncodeText(TextStr)

var ado_stream = new ActiveXObject("ADODB.Stream");
var tmpNode = xml_dom.createElement("tmpNode");
tmpNode.dataType = "bin.base64";
ado_stream.Charset = "utf-8";
ado_stream.Type = 2; // 1=adTypeBinary 2=adTypeText
if(ado_stream.state == 0)
{ // 0=adStateClosed 1=adStateOpen
ado_stream.Open();
}
ado_stream.WriteText(TextStr);
ado_stream.Position = 0;
ado_stream.Type = 1; // 1=adTypeBinary 2=adTypeText
tmpNode.nodeTypedValue = ado_stream.Read(-1); // -1=adReadAll
ado_stream.Close();
return tmpNode.text;
}
function Base64DecodeText(Base64Str)
{
var xml_dom = new ActiveXObject("Microsoft.XMLDOM");
var ado_stream = new ActiveXObject("ADODB.Stream");
var tmpNode = xml_dom.createElement("tmpNode");
tmpNode.dataType = "bin.base64";

ado_stream.Type = 2; // 1=adTypeBinary 2=adTypeText
var str = ado_stream.ReadText(-1); // -1=adReadAll
ado_stream.Close();
return str;
}
这个能实现不？谁帮忙改成VBS的
