Hi Michael,

I was able to work around the problem below by removing the platform tag.
For now, I am happy with legacy active registration.
I now have a working example of Calc extension in C++ (on lines of 
example/java/SpreadSheet/CalcAddins)
Thanks for your help.


I noticed that you are listed as one of the developers for soffice. Would you be able to take this 
code and introduce it as part of package ?
Same might be done for myRNG.tar.gz.
I think calc is an important part of soffice and having a c++ extension readily available would 
attract more users to it.
It took me days to get this working, but for anyone henceforth it should be 15 min.

Unfortunately, I am behind firewall and can't access gerrit. I am attaching the file with this 
email.
If there is a better way to get it as part of installation, I'll be happy to contribute.

Thanks
Neeraj

Hi Michael,

I tried your extension suggestion to convert examples/java/SpreadSheet/CalcAddins.java to C++.
I am having problem installing my extension using unpkg.
Error : The extension "my simple extension" does not work on this computer.
I tried various values in META-INF/manifest.xml : platform=linux_x86_64 and platform=all but I get 
the same error.

I probably did something wrong transporting the xml files or oxt files from the example.
The original example in java works for me.
Would you happen to have expertise in this area and time to help me out ?

I also came across the following link which states that regmerge is legacy. However, the CalcAddIn 
was using it, so I went with it too.

If that is the not the right way forward, please point me in the right direction.

Thanks
Neeraj

Based on above text, I looked at addIns but it doesn't seem like what I
need.  I don't want to be restricted to a function call. I need a
component running in scalc.

Can someone please advise what is the "fastest code as a C++ UNO
component " mean and where can I find more docs related to it.

C++ UNO components that are instantiated in-process currently do not go
through a bridge when interacting with the LO API (although there have
been varying opinions about changing that, since it makes maintaining
backward compatibility more difficult): for such components, calling a
LO API method (or being called from LO itself) is just a C++ virtual
function call.

the best documented way to get this performance benefit is to implement
your client code as an extension.

http://wiki.openoffice.org/wiki/Documentation/DevGuide/Extensions/Extensions

there may also be a way to get there with less efforts, there are some
variables to add additional service rdbs to the soffice process
(URE_MORE_SERVICES/URE_MORE_TYPES) but i don't have any experience with
them; probably there is some way to implement what you want to do as a
service and then start it from inside soffice, if all else fails via a
trivial BASIC macro :)
