Remarks

A FreshBooksConnection object represents a unique connection to FreshBooks. Use it in conjunction with FreshBooksCommand, FreshBooksDataReader, FreshBooksDataAdapter or other components for convenient interoperation with FreshBooks.

When you create an instance of FreshBooksConnection, all properties are set to their initial values. For a list of these values, see ConnectionString.

If the FreshBooksConnection goes out of scope, it is not closed. Therefore, you must explicitly close the connection by calling Devart.Common.DbConnectionBase.Close.

Note that FreshBooksConnection instance is not guaranteed to be thread safe. You should avoid using the same FreshBooksConnection in several threads at the same time. It is recommended to open a new connection per thread and to close it when the work is done. Actually, connections will not be created/disposed every time with the Pooling=true; connection string option - connections will be stored at connection pool. This boosts performance greatly.

A single FreshBooksConnection can be used by many FreshBooksCommand objects on the assumption that all operations will be done consecutively. In other words, you can not execute a SQL statement while an asynchronous operation is in progress.

This class supports cross-form data binding with the InterForm Technology.

Example

The following example creates a FreshBooksCommand and a FreshBooksConnection. The FreshBooksConnection is opened and set as the Connection property. The example then calls ExecuteNonQuery method, and closes the connection. To accomplish this, the ExecuteNonQuery is passed a connection string and a query string that is SQL INSERT statement.

csharp

public void InsertRow(string freshbooksConnectionString)
{
  // If the connection string is empty, use default.
  if(freshbooksConnectionString == "")
  {
    freshbooksConnectionString = 
        "API Version=Alpha;Access Token=3d3355b2beea67f9241400fbe28f0b116e3efd2f8a85dda3c35620acdc95cd60;Refresh Token=75836f50da63fc5bf81bb24598511ae131ea422e73d9f321b4c4a44e2dd1c67f;Company Name=Devart";
  }
  FreshBooksConnection myConn = new FreshBooksConnection(freshbooksConnectionString);
  string myInsertQuery = "INSERT INTO Client (Email, FirstName, LastName) VALUES ('[email protected]', 'John', 'Smith')";
  FreshBooksCommand freshbooksCommand = new FreshBooksCommand(myInsertQuery);
  freshbooksCommand.Connection = myConn;
  myConn.Open();
  try
  {
    freshbooksCommand.ExecuteNonQuery();
  }
  finally
  {
    myConn.Close();
  }
}

Visual Basic

Public Sub InsertRow(freshbooksConnectionString As String)
  ' If the connection string is empty, use default.
  If freshbooksConnectionString = "" Then
    freshbooksConnectionString = _
        "API Version=Alpha;Access Token=3d3355b2beea67f9241400fbe28f0b116e3efd2f8a85dda3c35620acdc95cd60;Refresh Token=75836f50da63fc5bf81bb24598511ae131ea422e73d9f321b4c4a44e2dd1c67f;Company Name=Devart"
  End If
  Dim myConn As New FreshBooksConnection(freshbooksConnectionString)
  Dim myInsertQuery As String = "INSERT INTO Client (Email, FirstName, LastName) VALUES ('[email protected]', 'John', 'Smith')"
  Dim freshbooksCommand As New FreshBooksCommand(myInsertQuery)
  freshbooksCommand.Connection = myConn
  myConn.Open()
  Try
    freshbooksCommand.ExecuteNonQuery()
  Finally
    myConn.Close()
