DDEMETA is a server application that uses the Dynamic Data Exchange Management Library (DDEML).

To use DDEMETA, perform the following five steps:

Start DDEMETA.

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

Start a DDE client application to initiate a conversation with DDEMETA. In the client, use the application name "DDEMETA" and the topic "Test".

After the conversation is established, the client application can request any "item" of type CF_METAFILEPICT from the server.

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:
