Where is the issue in GetProperties Value ?

I called my function:

function propValueList(string,object)
{
p=object;
props = aqObject.GetProperties(p);
Log.Message(string);
while (props.HasNext())
{
prop = props.Next();
Log.Message (prop.Value);
}

}

But When I run this one,I got the following issue:

,,htmlfile not implemented".

But the prop.Name is okay,the Value not working at all.

Can you help me?
