<p><strong>Description:</strong></p>
<p>The <code>Cancel</code> method cancels an outstanding asynchronous
call. </p>
<p>If a cancel is sent, but the asynchronous call has already been completed,
then <code>result.Errorcode</code> is set to <code>0</code> (success).</p>
<p>This is a synchronous method.</p>
<p><strong>Syntax:</strong></p>
<pre class="codeblock" id="GUID-9844A620-3E6A-4552-9A0E-D7F5A2D5CF81">result = so.IAppManager.Cancel(criteria);</pre>
<p><strong>Arguments:</strong></p>
<ul>
<li><p><code>criteria</code>:</p>
<p>This is an object with the <code>TransactionID</code> property
(number). <code>criteria.TransactionID</code> specifies the transaction
ID of the asynchronous call to cancel. The transaction ID is the <code>result.TransactionID</code> value
that was returned as part of the result of the initial call. </p>
</li>
</ul>
<p><strong>Return value:</strong></p>
<p>The <code>Cancel</code> method returns an object that contains
an error code and an error message.</p>
