variable = objectPtr->GetProperty(); // get property value
objectPtr->PutProperty(value); // set property value
objectPtr->PutRefProperty(&value); // set property with object pointer

using:
FieldObj->GetType();
return value:
返回值在DataTypeEnum中，参看MSDN

BOOL CADORecordset::GetFieldInfo(FieldPtr pField, CADOFieldInfo* fldInfo)
{
memset(fldInfo, 0, sizeof(CADOFieldInfo));

strcpy(fldInfo->m_strName, (LPCTSTR)pField->GetName());
fldInfo->m_lDefinedSize = pField->GetDefinedSize();
fldInfo->m_nType = pField->GetType();
fldInfo->m_lAttributes = pField->GetAttributes();
if(!IsEof())
fldInfo->m_lSize = pField->GetActualSize();
return TRUE;
}
struct CADOFieldInfo
{
char m_strName[30];
short m_nType;
long m_lSize;
long m_lDefinedSize;
long m_lAttributes;
short m_nOrdinalPosition;
BOOL m_bRequired;
BOOL m_bAllowZeroLength;
long m_lCollatingOrder;
};

好好看看Carlos 的代码你会有很大收获的
