Thread Subject: Update Subsystem MaskDisplay from a Library with Subversion Info

Hello everybody,

I am trying to create a Model Block to show the version control info obtained from subversion. I know that under windows we can not use the “customverctr.m” to use subversion with the default Model Info Block. In addition I download PushOk SVNSCC (www.pushok.com) but it doesn’t work. That is the reason why I am trying to development my own SVN-Model Info.

My idea, as I said before is create a Subsystem, called SVN-Model Indo which I can place in any Model and it recognized the file of the Model and ask subversion for the pertinent information and display it as a Mask Display. I got to work it for individual Models, but when I place then individual models inside a library I start getting very weird behaviour. I know that the main problem is that I can not modify a SVN-Model Info block inside the model inside the library. But I break the link setting the LinkStatus to ‘none’. However it still gives me very weird behaviour.

So please if anyone could help me I will be very very grateful.

Thanks in advances.

An illustration of my “suppose” library can be found here <http://www.di3d.eu/svn.jpg>.

PD: Is there anything in Matlab/Simulink like “this” in c++ to refer to the actual instance?

[SVN-MODEL BLOCK CODE]
