Extracting a memo field value from COleVariant

Hiya ppl ,
Could anyone tell me how to extract a memo field value from a COleVariant object? I could extract string, date, and numeric fields but I am stuck on how to get a memo field value?

For example, this is how I extract a string value from COleVariant:

CString TTableClass::fGetStringValue(CString sField)
{
COleVariant oVariant;

oVariant = moTable.GetFieldValue(sField);
return LPCSTR(oVariant.bstrVal);
}

But how to do it for memo field? And where to store it? Is there a specific object in MFC to store memo value? Or do I store it in CString object?

Thanks in advance,
Tatang
