|
|
<para>
|
|
<function>com_get_active_object</function> is similar to creating a new
|
|
instance of a <xref linkend="class.com"/> object, except that it will
|
|
only return an object to your script if the object is already running.
|
|
OLE applications use something known as the "<literal>Running Object Table</literal>" to
|
|
allow well-known applications to be launched only once; this function
|
|
exposes the COM library function GetActiveObject() to get a handle on a
|
|
running instance.

<para>

<parameter>progid</parameter> must be either the ProgID or CLSID for

There are a variety of reasons why this function might fail, the most
|
|
common being that the object is not already running. In that situation,
|
|
the exception error code will be <constant>MK_E_UNAVAILABLE</constant>;
|
|
you can use the <literal>getCode</literal> method of the exception object
|
|
to check the exception code.

<warning>
|

<para>
|
|
Using <function>com_get_active_object</function> in a web server context
|
|
is not always a smart idea. Most COM/OLE applications are not designed
|
|
to handle more than one client concurrently, even (or especially!)
|
|
Microsoft Office. You should read <link
|
|
xlink:href="&url.msoffice.serverside;">Considerations for Server-Side
|
|
Automation of Office</link> for more information on the general issues
|
|
involved.
