CommitTransaction
ODBPPLib.IODBPP.CommitTransaction executes the transaction log file, releasing all object locks if releaseObjectLocks is true else the current transaction will retain all the objects lock making CommitTransaction funtion like a save point.void CommitTransaction( bool releaseObjectLocks );
Parameters
| releaseObjectLocks | if this is set to false, this method acts as a save point, committing all adds, edits and deletes, but not releasing any object locks. |
Return Values
Remarks
- If this method is not called before EndTransaction or CloseDatabase, then the transaction is aborted.
- Then releaseObjectLocks is set true, the object within the table handles are removes so any call to ReadObject or DeleteObject using ODBPP.NEXT or ODBPP.PREVIOUS will fail.

- C#
public static uint FIRST_TABLE = 1;
private void button1_Click(object sender, EventArgs e){
try{
ODBPPLib.ODBPP odbpp = new ODBPPLib.ODBPP();
odbpp.OpenDatabase("C:\\My\\Database\\Control\\File.odc");
odbpp.BeginTransaction(odbpp.SHARED, 60000);
odbpp.OpenTable(FIRST_TABLE);
ODBPPLib.DatabaseObject obj = odbpp.NewObject(FIRST_TABLE);
obj.WriteField("First", 456);
