Count Property Example (VB)

This example demonstrates the Count property with two collections in the Employee database. The property obtains the number of objects in each collection, and sets the upper limit for loops that enumerate these collections. Another way to enumerate these collections without using the Count property would be to use For Each...Next statements.

'BeginCountVB

    'To integrate this code
    'replace the data source and initial catalog values
    'in the connection string
    
Public Sub CountX()

    ' recordset and connection variables
   Dim rstEmployees As ADODB.Recordset
   Dim Cnxn As ADODB.Connection
   Dim strSQLEmployees As String
   Dim strCnxn As String
   
   Dim intLoop As Integer

   ' Open a connection
   Set Cnxn = New ADODB.Connection
   strCnxn = "Provider=sqloledb;Data Source=MyServer;Initial Catalog=Pubs;User Id=sa;Password=; "
   Cnxn.Open strCnxn
   
   ' Open recordset with data from Employee table
   Set rstEmployees = New ADODB.Recordset
   strSQLEmployees = "Employee"
   'rstEmployees.Open strSQLEmployee, Cnxn, , , adCmdTable
   rstEmployees.Open strSQLEmployees, Cnxn, adOpenForwardOnly, adLockReadOnly, adCmdTable
   'the above two lines opening the recordset are identical as
   'the default values for CursorType and LockType arguments match those specified

   ' Print information about Fields collection
   Debug.Print rstEmployees.Fields.Count & " Fields in Employee"
   
   For intLoop = 0 To rstEmployees.Fields.Count - 1
      Debug.Print "   " & rstEmployees.Fields(intLoop).Name
   Next intLoop

   ' Print information about Properties collection
   Debug.Print rstEmployees.Properties.Count & " Properties in Employee"
   
   For intLoop = 0 To rstEmployees.Properties.Count - 1
      Debug.Print "   " & rstEmployees.Properties(intLoop).Name
   Next intLoop

    ' clean up
   rstEmployees.Close
   Cnxn.Close
   Set rstEmployees = Nothing
   Set Cnxn = Nothing

End Sub
