I figured out how to access columns in a row by using "_bstr_t xBar2 = (_bstr_t) m_Recordset->Fields->GetItem("xbar_2")->Value;".

Can someone please tell me how to access the columns by using a column# instead of name?

I believe its simply:

_bstr_t xBar2 = (_bstr_t) m_Recordset->Fields->GetItem(1)->Value;

that is, provide a number instead of a string to GetItem.

Quoting from the msdn:

In Visual C++, the GetItem(index) method returns a member of the collection. Index is a Variant, the value of which is either a numerical index of the member in the collection, or a string containing the name of the member.

hope this helps

GetItem(colIndex) should work right?

Plz refer to code at
