+based dictionary store</title><prolog><metadata><keywords/></metadata></prolog><conbody>
+<p><codeph>CDictionaryFileStore</codeph> is a concrete implementation of a
+dictionary store and uses a file store in its implementation.</p>
+<p>Although the need for a file based dictionary store is driven by the application
+architecture, the following code fragments illustrate the way this store can
+be used.</p>
+<p>The code fragments shown here create and read a file based dictionary store.
+This dictionary store is differentiated from other dictionary stores by the
+UID whose value is <codeph>0x0001</codeph>.</p>
+<p>It should be noted that the values assigned to the UIDs are purely <i>arbitrary</i> and
+are used for <i>illustrative purposes only</i>.</p>
+<section><title>Creating the dictionary store</title> <p>This code fragment
+constructs an object of type <codeph>TClass</codeph> and stores it in the
+dictionary store, associating the stream with the UID whose value is 0x0002.</p> <p>Note
+that a dictionary write stream is needed to write streams to a dictionary
+store.</p> <codeblock id="GUID-AF74B440-E5A9-5A47-84E1-09E2243BB911" xml:space="preserve">_LIT(KFileName,"C:\\data\\stdict.dat");
