Accessing the Windows Registry [message #165550]

Hi,

I'm interested in accessing the windows registry from Eclipse. Our plugin
would like to query information about another Windows application that it
needs to inter-operate with.

I searched the newsgroups and found that to access the registry from
Eclipse the suggested approach is to use the following LGPL open source
plugin:

http://www.beq.ca/tech/Products/jreg_key.shtml

We'd rather not have to depend on such a complete library as this, we
literally just need to query one key in the registry so this seems like a
fairly heavyweight solution.

I'm wondering is it possible to make use of some of Eclipse's own registry
implementation. I can see code where Eclipse accesses the registry (e.g.
org.eclipse.swt.program.Program.getKeyValue) by making JNI calls via the
org.eclipse.swt.internal.win32.OS class, but I can't find anywhere that
this code is made publicly available thru some API. The OS class is in an
internal package so we shouldn't rely on this. And the getKeyValue method
on the Program class has package visibility - so close and yet so far :)

Has anyone else had any luck with this? Any help much appreciated!

Paul.

You are probably better off finding the native call in the SWT code and
recreate your own dll.
Sorry I don't know where is the code is, but you can probably find that
by asking the question on the swt newsgroup.

Why not just use the 1.4.2 API ?

The 1.4.2 API is limited to keys under local machine or user
Softare/JavaSoft/Prefs .
If there's not one already, I suggest opening a PR for a public API to
access the whole Windows registry.
