- DDE Client Sample
- DDE Server Sample
-
- DESCRIPTION:
- The DDE Sample contains two applications.
- They are the DDE Client and DDE Server.
- Each is located in a subdirectory.
- These two applications start DDE
- conversations with each other and can
- perform data requests to the other
- application. In addition they can be
- hotlinked together for automatic data
- requests. Classes used include
- IDDEClientConversation,
- IDDEClientAcknowledge, IDDEClientEndEvent,
- IDDEClientHotLinkEvent,
- IDDEClientHotLinkSet, IDDEBeginEvent,
- IDDEEndEvent, IDDETopicServer,
- IDDERequestDataEvent, IDDEServerHotLinkEvent,
- and IDDEAcknowledgeEvent.
-
- CONCEPT/FEATURE:
- Sample program for demonstrating interprocess
- communications using Dynamic Data Exchange (DDE).
-
- HOW TO BUILD THE PROJECT FROM THE COMMAND LINE:
- From within the directory containing the sample, simply type:
- NMAKE
-
- HOW TO BUILD THE PROJECT FROM WITHIN THE WORKFRAME ENVIRONMENT:
- Refer to the standard Workframe BUILD instructions
-
- HOW TO RUN THE PROJECT FROM THE COMMAND LINE:
- From within the directory containing the sample, simply type
- the name of the executable:
- DDECLNT
- and
- DDESERV
-
- HOW TO RUN THE PROJECT FROM WITHIN THE WORKFRAME ENVIRONMENT:
- Refer to the standard Workframe RUN instructions
-
- SPECIAL NOTES:
- If the sample fails to execute or
- abnormally ends, you can get
- more information about the failure
- by turning on the ICLUI trace.
- This is done by setting the
- environment variable ICLUI_TRACE
- as follows:
-
- set ICLUI_TRACE=ON
- set ICLUI_TRACETO=STDERR
-
- ICLUI_TRACETO controls where
- the trace information is reported.
- With tracing turned on, ICLUI
- exception text will be written to a
- standard error file. For example:
-
- sample >sample.out 2>&1
-
- The exception data is now in the file
- 'sample.out'.
-
- ADDITIONAL HARDWARE/SOFTWARE REQUIREMENTS:
- Dynamic Data Exchange restrictions for Win32s :
- The following functions are not supported for DDE on Win32s platforms :
- - IDDEClientConversation :: beginHotLink()
- - IDDEClientConversation :: endHotLink()
- - IDDETopicServer :: hotLinkUpdate()
- You can use these member functions to establish a DDE Hot Link but
- subsequent data requests and hot link updates may be corrupted.
-
