Description Rainer Bielefeld 2003-09-05 16:08:30 UTC
I added some files to reproduce the problem. Because of the absolute links that
will only work if you unzip the example file into a path
so that the last file "texttest2.sxw" will be in

Might be better that you create your own files, I will explain with my path

Steps to reproduce:

1. create 3 files

2. add to "texttest1.sxw" text "Date: " and actual date with "Insert Fields"
3. add to "texttest2.sxw" text "Time: " and actual time with "Insert Fields"
4. goto "texttest0.sxw", write something like "Date from texttest1: "
5. goto "texttest1.sxw", mark field "date", Cntrl.-v
6. goto "texttest0.sxw" copy field after your text with menu: 
7. Set into "texttest0.sxw" a link to time in "texttest2.sxw" in the same way.
8. Close all 3 files and give network permissions "read/write" to all test 
9. go to another PC in your LAN and open "texttest0.sxw" with "Modify Links"
   via LAN.
   expected: "texttest0.sxw" will be opened with actual date and time from other
             testfiles by dde.
   actual: errormessage: "D:\.......\DDE_NET_ABSOLUTE_PROBLEM\texttest0.sxw not 
           found" (same for second source file)

It seems that this happens because of the absolute link "D:\...."
A Network link would look like "\\RAINERSDESKTOP\DDE_TEXT_PRO\testtext2"
But should that not work transparent?

I tested with files from issue 19100 with relative DDE- links, that works as
expected without problems, excepted the special issue 19100 problems, of course ;-)

I m no specialist for WIN DDE specifications and so I do not know whether that
should work via Network, so UNCONFIRMED. I will install WORD and test LAN - DDE-
behaviour again.

TM->SBA: Looks more like a writer-apps. - issue with a "link-problem"
than a framework problem to me. Please have a look, thanks !

hi michael, i can confirm this behaviour, but i also do not know if this is a 
ms-os specific problem or not. i think the path should be saved relativ to the 
just have in my mind: two people working on a network share both have different 
drive letters for this share, the could not work on a document like this from 
rainer. i set this to new with target OOo later. if i am wrong and this is a ms 
problem please set this to invalid

MRU->SBA: I am firm with OLE, but not really with DDE. So we need a volunteer
for this...

please have a look

ES->FME: as discussed, please have a look. Thanx!
Comment 8 frank.meies 2005-07-22 15:15:04 UTC
FME->rainerbielefeld: I'm not sure if I understand the problem. If you change
the path of the dde source file to \\your_machine\path\to\files everything
should work as expected, doesn't it?

You are right, so it is.
Comment 10 frank.meies 2005-07-25 08:33:10 UTC
FME->rainerbielefeld: I still do not understand the problem. Let me sum up: You
have a document containing DDE links pointing to a resource in your LAN. Because
the DDE sources are in your LAN, the DDE link has to contain a network address
like "\\your_machine\your\path". This works as expected, so what's the problem?
Comment 11 Rainer Bielefeld 2005-07-25 08:44:14 UTC
A very general description of the problem is: "DDE Links created by standard way
do not work for document access via network". Network access will be required
very often, so links shoud work always via Network

That's why  links are absolute in a way that can not work via network.

Now we have to decide:
- should DDE-Links be created relatiev as standard (pls also see  issue 19100, and 
  is tat in accordence to DDE-Standards?
- or: should OOo inser DDE-hyperlinks like "\\your_machine\your\path" as standard?
- or: should OOo be able to transform absolute links "internal" if it sees 
  that access is via network
- or: should we add some hints in HELP
- pr: ....

Result shoud be that we have an easy way to have DDE-access working on
stand-alone-PC _and_ vie network

FME->rainerbielefeld: Thank you for your explanation. I'll pass this issue to
the user experience team to make a decision.

FME->FL: Please have a look.
