     7 <p><strong>Description:</strong></p>
       
     8 <p>The <code>LaunchApp</code> method launches an application based
       
     9 on a unique ID for the application (UID). It also provides a way to open a
       
    10 specific document (by specifying a document path), even if it is not the default
       
    11 file type for the application being launched.<span> For
       
    12 example, you can specify a path to a document with a <code>.txt</code> extension
       
    13 to open in WordPad, even though Notepad is the default application for .txt
       
    14 files.</span></p>
       
    15 <p>The application can be launched as chained (embedded) or stand-alone.
       
    16 For more information about embedded and stand-alone applications, see section <a href="GUID-E092BF10-C076-4476-9E80-87919940201B.html#GUID-E092BF10-C076-4476-9E80-87919940201B">Accessing and launching installed applications</a>.</p>
       
    17 <p>This method can be called both synchronously and asynchronously.</p>
       
    18 <p><strong>Syntax:</strong></p>
       
    19 <p>For synchronous calls:</p>
       
    20 <pre class="codeblock" id="GUID-21A6DD8A-D123-452E-9CD3-38987BE08CB2">result = so.IAppManager.LaunchApp(criteria);</pre>
       
    21 
       
    22 <p>For asynchronous calls:</p>
       
    23 <pre class="codeblock" id="GUID-07FA9E54-0E1E-4F9C-989D-2A9CF8E8C08F">result = so.IAppManager.LaunchApp(criteria, callback);</pre>
       
    24 
       
    25 <p><strong>Arguments:</strong></p>
       
    26 <ul>
       
    27 <li><p><code>criteria</code>:</p>
       
    28 
       
    29 <p>This is an object that specifies which application to launch. For more
       
    30 information about the object properties and how to define them, see section <a href="GUID-7DD6AB91-0582-4A46-9E19-2F12DC2FE674.html#GUID-7DD6AB91-0582-4A46-9E19-2F12DC2FE674">Criteria for launching an application</a>.</p>
       
    31 
       
    32 </li>
       
    33 <li><p><code>callback</code>:</p>
       
    34 
       
    35 <p>The <code>callback</code> argument is the name of the method
       
    36 that is executed when an asynchronous <code>LaunchApp</code> call
       
    37 has status information to return. You must define this method separately.
       
    38 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
       
    39 define the <code>callback</code> method.</p>
       
    40 <p>This argument is used only with an asynchronous <code>LaunchApp</code> call.</p>
       
    41 
       
    42 </li>
       
    43 </ul>
       
    44 <p><strong>Return value:</strong></p>
       
    45 <p>If synchronous, the <code>LaunchApp</code> method returns an
       
    46 object that contains an error code and an error message.</p>
