   TITLE     : How to Obtain Microsoft Support Files from Online Services
DDEMETA is a server application that uses the Dynamic Data Exchange Management Library (DDEML).

To use DDEMETA, perform the following five steps:

1. Start DDEMETA.

2. Choose DDE Init from the Sample menu to register DDEMETA with the 

   DDEML.
3. Start a DDE client application to initiate a conversation with 
   DDEMETA. In the client, use the application name "DDEMETA" and the
   topic "Test".
4. After the conversation is established, the client application can 
   request any "item" of type CF_METAFILEPICT from the server.
5. When DDEMETA receives the request, it will read the TEST.WMF file 
   from the disk and pass it to the client application.
To test DDEMETA, request a CF_TEXT item. Note that the "item" reference is never checked; therefore, any item name works.

Note: This program will not read "placeable" metafiles. For more information on "placeable" metafiles, query on the following words in the Microsoft Knowledge Base:
