Wine, WineLib and "Programming Windows 95"

2.15.1. Chapter 17 - ddepop1

Last updated: 2001/2/4

Description

This is a DDE server program which can provide information about the population of the USA states to a DDE client.

Wine tests

• Seems to work fine. If there's a problem I'll report it in the client anyway.

Winelib tests

• ddepop1.c is incorrect. It uses NULL where we should really have a '0', thus this compilation warning (same as on Windows). Since it's just warnings it does not warrant a patch, we can just ignore them:
  

  ddepop1.c: In function `WndProc':
  ddepop1.c:123: warning: comparison between pointer and integer
  ddepop1.c:124: warning: comparison between pointer and integer
  ddepop1.c: In function `ServerProc':
  ddepop1.c:359: warning: comparison between pointer and integer

2.15.2. Chapter 17 - ddepop2

Last updated: 2000/12/2

Description

Same as ddepop1 but using the DDEML (DDE Management Library). it also updates the data every five seconds.

Wine tests

• Displays a long list of messages warning us that DdePostAdvise is a stub:

  fixme:ddeml:DdePostAdvise (1,0,0): stub
      

• When closing the application I get the following messages:

  fixme:ddeml:DdeNameService (1,0,0,2): stub
  fixme:ddeml:DdeUninitialize (1): partial stub
      

Winelib tests

• Same as with Wine.
