+Description
+===========
+  The DXErr sample allows users to enter a numerical HRESULT and get back
+  the string equivalent as well as its description.  For example, entering 
+  0x8878000a will return 
+        HRESULT: DSERR_ALLOCATED
+        Description: The call failed because resources (such as a priority 
+        level) were already being used by another caller.
