Field2.Size Property

  • Article
Access Developer Reference

Sets or returns a value that indicates the maximum size, in bytes, of a Field2 object.

Syntax

expression.Size

expression   A variable that represents a Field2 object.

Remarks

For an object not yet appended to the Fields collection, this property is read/write.

For fields (other than Memo type fields) that contain character data, the Size property indicates the maximum number of characters that the field can hold. For numeric fields, the Size property indicates how many bytes of storage are required.

Use of the Size property depends on the object that contains the Fields collection to which the Field2 object is appended, as shown in the following table.

When you create a Field2 object with a data type other than Text, the Type property setting automatically determines the Size property setting; you don't need to set it. For a Field2 object with the Text data type, however, you can set Size to any integer up to the maximum text size (255 for Microsoft Access database engine databases). If you do not set the size, the field will be as large as the database allows.

For Long Binary and Memo Field2 objects, Size is always set to 0. Use the FieldSize property of the Field2 object to determine the size of the data in a specific record. The maximum size of a Long Binary or Memo field is limited only by your system resources or the maximum size that the database allows.

Example

This example demonstrates the Size property by enumerating the names and sizes of the Field2 objects in the Employees table.

Visual Basic for Applications 
  Sub SizeX()

Dim dbsNorthwind As Database
Dim tdfEmployees As TableDef
Dim fldNew As Field2
Dim fldLoop As Field2


Set dbsNorthwind = OpenDatabase("Northwind.mdb")
Set tdfEmployees = dbsNorthwind.TableDefs!Employees


With tdfEmployees


  ' Create and append a new Field object to the 
  ' Employees table.
  Set fldNew = .CreateField("FaxPhone")
  fldNew.Type = dbText
  fldNew.<strong class="bterm">Size</strong> = 20
  .Fields.Append fldNew

  Debug.Print "TableDef: " &amp; .Name
  Debug.Print "  Field.Name - Field.Type - Field.Size"

  ' Enumerate Fields collection; print field names, 
  ' types, and sizes.
  For Each fldLoop In .Fields
     Debug.Print "    " &amp; fldLoop.Name &amp; " - " &amp; _
        fldLoop.Type &amp; " - " &amp; fldLoop.<strong class="bterm">Size</strong>
  Next fldLoop

  ' Delete new field because this is a demonstration.
  .Fields.Delete fldNew.Name
