<section><title>Description</title> <p>This example comprises an embedded

application (<filepath>embedded.dll</filepath>) and the stub (<filepath>embedded.exe</filepath>).

The stub is essentially an empty executable that launches the embedded application,

which is wrapped up as an ECOM plug-in. <filepath>Embedded.dll</filepath> builds

on the <xref href="GUID-1D7BD70F-40A3-53FF-8150-A9CAFA4D01D8.dita">minimal</xref> UI

application. </p> <p>The application is defined in the registration file (<filepath>embedded_reg.rss</filepath>)

as an embedded and/or a stand-alone application: </p> <codeblock id="GUID-234F184B-21E6-5590-BC19-A60629F73580" xml:space="preserve">embeddability=KAppEmbeddable;</codeblock> <p>and <codeph>KAppEmbeddable</codeph> is defined in <filepath>appinfo.rh</filepath>. </p> </section>
