Apache OpenOffice (AOO) Bugzilla – Issue 27251
Multiple DDE conversations on same DDE service
Last modified: 2013-10-08 04:42:50 UTC
In the OOo spreadsheet application, you can create a DDE Advise link to another application by typing =DDE("service";"topic";"item") into a cell, for example, =DDE("excel";"Book1";"r1c1") will take data from R1C1 of an Excel spreadsheet. The problem I see is that OO spreadsheet will open a new DDE conversation for every cell that is linked in this manner. While this may not matter for a small number of cells, it matters a great deal for large numbers of cells - it is very inefficient. This behaviour causes some serious problems with another tool we wish to use. Most DDE-enabled programs, including Excel, will not open a new conversation to the DDE server if there is already a conversation open to the DDE service. Additional DDE Advise loops are simply established on the existing conversation. This is considerably faster and more resource efficient. There is a little more book-keeping to do to ensure that the conversation is only closed when the last Advise loop is removed, but I suggest that sharing DDE conversations is a strongly desirable behaviour for both speed and resource efficiency reasons.
