     7 <p><strong>Description:</strong></p>
       
     8 <p>The <code>Cancel</code> method cancels an outstanding asynchronous
       
     9 call made with a Logging Service API method.</p>
       
    10 <p>If a cancel is sent, but the asynchronous call has already been completed,
       
    11 then <code>result.ErrorCode</code> is set to <code>0</code> (success).</p>
       
    12 <p>This is a synchronous method.</p>
       
    13 <p><strong>Syntax:</strong></p>
       
    14 <pre class="codeblock" id="GUID-6C88D4B9-532D-4BC2-B760-D774AAA9F805-GENIDd0e54927">result = so.IDataSource.Cancel(criteria);</pre>
       
    15 <p><strong>Arguments:</strong></p>
       
    16 <ul>
       
    17 <li><p><code>criteria</code>:</p>
       
    18 
       
    19 <p>This is an object with the <code>TransactionID</code> property
       
    20 (number). <code>criteria.TransactionID</code> specifies the transaction
       
    21 ID of the asynchronous call to cancel. The transaction ID is the <code>result.TransactionID</code> value
       
    22 that was returned as part of the result of the initial call.</p>
       
    23 
       
    24 </li>
       
    25 </ul>
       
    26 <p><strong>Return value:</strong></p>
       
    27 <p>The <code>Cancel</code> method returns an object that contains
       
    28 an error code and an error message.</p>
