Detailed Description

Used to define the fields in a database (DBF file).

Generally one would define an xbSchema array to be passed to xbDbf::CreateDatabase() to define the fields in the database.

For example, one might create a declaration as follows:

xbSchema MyRecord[] = 
{
  { "FIRSTNAME", XB_CHAR_FLD,     15, 0 },
  { "LASTNAME",  XB_CHAR_FLD,     20, 0 },
  { "BIRTHDATE", XB_DATE_FLD,      8, 0 },
  { "AMOUNT",    XB_NUMERIC_FLD,   9, 2 },
  { "SWITCH",    XB_LOGICAL_FLD,   1, 0 },
  { "FLOAT1",    XB_FLOAT_FLD,     9, 2 },
  { "FLOAT2",    XB_FLOAT_FLD,     9, 1 },
  { "FLOAT3",    XB_FLOAT_FLD,     9, 2 },
  { "FLOAT4",    XB_FLOAT_FLD,     9, 3 },
  { "MEMO1",     XB_MEMO_FLD,     10, 0 },
  { "ZIPCODE",   XB_NUMERIC_FLD,   5, 0 },      
  { "",0,0,0 }
};

Note that the last xbSchema in an array must be a "null" entry like the one above:

{ "",0,0,0 }

To indicate the end of the array.
