Resync method example (VJ++)

Applies to: Access 2013, Office 2013

This example demonstrates using the Resync method to refresh data in a static recordset.

 
// BeginResyncJ

import com.ms.wfc.data.*; 
 
public class ResyncX 
{ 
 // The main entry point of the application.

 // Declarations. 
 BufferedReader in = 
 new BufferedReader(new InputStreamReader(System.in)); 
 String strCnn = "Provider='sqloledb';Data Source='MySqlServer';" + 
 "Initial Catalog='Pubs';Integrated Security='SSPI';";

 { 
 // Open recordset for Titles table.

 rstTitles.setLockType(AdoEnums.LockType.BATCHOPTIMISTIC); 
 rstTitles.open("Titles", strCnn, AdoEnums.CursorType.STATIC, 
 AdoEnums.LockType.BATCHOPTIMISTIC, 
 AdoEnums.CommandType.TABLE); 
 
 // Change the type of the first title in the recordset. 
 rstTitles.getField("type").setString("database"); 
 
 // Display the results of the change. 
 System.out.println("\n\n\tBefore resync:\n" + "\tTitle - " + 
 rstTitles.getField("title").getString() +

 // Resync with database and redisplay the results. 
 rstTitles.resync();

 // If there are any errors in the collection, print them. 
 if( nCount > 0); 
 { 
 // Collection ranges from 0 to nCount - 1 
 for (i = 0; i< nCount; i++) 
 { 
 ErrItem = Cnn1.getErrors().getItem(i); 
 System.out.println("\t Error number: " + ErrItem.getNumber() 
 + "\t" + ErrItem.getDescription() ); 
 } 
 } 
 
 } 
 
 // PrintIOError Function
