I'm trying to return some information using the openschema as seen below


    Variant tvars[3] = { Unassigned(), Unassigned(), "tablename" };

    TADODataSet*  dataSet = new TADODataSet(NULL);
    std::auto_ptr<TADODataSet> auto_dataSet(dataSet);

    ADOConnection->OpenSchema(siPrimaryKeys , VarArrayOf(tvars, 2), NULL,
dataSet);

    //where tablename is the name of one of the tables within my database


This seems to compile ok but when it is executed it returns the following
error

    "Arguments are of the wrong type, are out of acceptable range, or are in
conflict with one another."

I unfortunately don't know a lot about OpenSchema and was using someone
else's code they posted earlier.

Any Help as to where I am going wrong would be greatly appreciated.
