I have struct like this
struct CAdoFieldInfo
      // The name of field
      char m_strName[30];
      // the field type
      short m_nType;
      // The field size
      long m_lSize;
            // the attributes of field
      long m_lAttributes;
      // the ordinal position of current field
      short m_nOrdinalPosition;
      BOOL m_bRequired;  
      BOOL m_bAllowZeroLength;
      long m_lCollatingOrder;  

I want to define my fields like this

{ 'fieldname',adchar,20,YESNO    }

You could do that like
CAdoFieldInfo afi = { "fieldname",adchar,20,YESNO, 42, TRUE, TRUE, MyOrder};

Or, alternatively, you can set the members individually:
CAdoFieldInfo afi;


afi.m_nType = addchar;

afi.m_lSize = 20;

afi.m_lAttributes = YESNO;

afi.m_nOrdinalPosition = 42;

afi.m_bRequired = TRUE;

afi.m_bAllowZero = TRUE;

afi.m_lCollatingOrder = MyOrder;

                                 "fieldname3",adchar,20,YESNO, 42, TRUE, TRUE, MyOrder;

Why You Should Analyze Threat Actor TTPs

After years of analyzing threat actor behavior, it’s become clear that at any given time there are specific tactics, techniques, and procedures (TTPs) that are particularly prevalent. By analyzing and understanding these TTPs, you can dramatically enhance your security program.

Fot the latter one, you need an array of structs, e.g.
CAdoFieldInfo afi[3] = 


  { "fieldname",adchar,20,YESNO, 42, TRUE, TRUE, MyOrder},

  { "fieldname2",adchar,20,YESNO, 42, TRUE, TRUE, MyOrder},

  { "fieldname3",adchar,20,YESNO, 42, TRUE, TRUE, MyOrder}

Hm, I am afraid I won't be able to clarify that in a single comment. Check out these articles, both come with full source code: ("
ADO MFC Wrapper classes") ("Updating and Adding Database Records Through ADO")
