|
7 <p><strong>Description:</strong></p> |
|
8 <p>The <code>Delete</code> method deletes a calendar from the device |
|
9 or one or more entries from a calendar. Entries are deleted from the specified |
|
10 calendar or, if no calendar is specified, from the default one.</p> |
|
11 <p>For deleting a calendar, this method is called synchronously. For deleting |
|
12 calendar entries, this method can be called both synchronously and asynchronously.</p> |
|
13 <p><strong>Syntax:</strong></p> |
|
14 <p>For synchronous calls:</p> |
|
15 <pre class="codeblock" id="GUID-13F75024-C303-4EF3-9789-B417233B35C8">result = so.IDataSource.Delete(criteria);</pre> |
|
16 |
|
17 <p>For asynchronous calls:</p> |
|
18 <pre class="codeblock" id="GUID-CA0558EF-F29E-4C1B-87D3-17401F7BF327">result = so.IDataSource.Delete(criteria, callback);</pre> |
|
19 |
|
20 <p><strong>Arguments:</strong></p> |
|
21 <ul> |
|
22 <li><p><code>criteria</code>:</p> |
|
23 |
|
24 <p>This is an object that specifies which calendar or calendar entries |
|
25 to delete. For more information about the object properties and how to define |
|
26 them, see section <a href="GUID-11652F7C-4A0A-432D-A7BE-E9C27C32319A.html#GUID-11652F7C-4A0A-432D-A7BE-E9C27C32319A">Criteria for deleting calendar information</a>.</p> |
|
27 |
|
28 </li> |
|
29 <li><p><code>callback</code>:</p> |
|
30 |
|
31 <p>The <code>callback</code> argument is the name of the method |
|
32 that is executed when an asynchronous <code>Delete</code> call has |
|
33 results or status information to return. You must define this method separately. |
|
34 Follow the instructions in section <a href="GUID-C7C3B541-8D28-4DC6-9003-ECF57F26C608.html#GUID-C7C3B541-8D28-4DC6-9003-ECF57F26C608">Defining the callback handler for an asynchronous method</a> to |
|
35 define the <code>callback</code> method.</p> |
|
36 <p>This argument is used only with an asynchronous <code>Delete</code> call.</p> |
|
37 |
|
38 </li> |
|
39 </ul> |
|
40 <p><strong>Return value:</strong></p> |
|
41 <p>If synchronous, the <code>Delete</code> method returns an object |
|
42 that contains an error code and an error message.</p> |
|
43 <p>If asynchronous, the method returns an object that contains a transaction |
|
44 ID for the <a href="GUID-C7C3B541-8D28-4DC6-9003-ECF57F26C608.html#GUID-C7C3B541-8D28-4DC6-9003-ECF57F26C608"><code>callback</code></a> instance, |
|
45 an error code, and an error message. When the asynchronous call has completed, <code>callback</code> returns |
|
46 an object that contains an error code and an error message (see <a href="GUID-C7C3B541-8D28-4DC6-9003-ECF57F26C608.html#GUID-E43BC9EA-3EBE-4C7F-A57E-A1C33BB01CF4">Table: Callback return value</a>).</p> |
