Hi,

   Thanks for your reppy. I really happy to receive this email. Thanks a
lot :-)
Anyway.... look like this is a problem to me.... yeah, I just wanted to
access the Windows registry... at this moment...
  hmm, one question, it is possible that Jawin can some how provide
another methods just for Win98 or WinME when Unicode not presented ?

Thanks again... really~ thanks alot...
ohhh yeah! sorry bout the bug list~ yeah, it is mine.... coz I saw it
transfer back to sourceforge, so a... I though it might be good if I open
a bug list at there... sorry bout that  :-P

Thanks again

Thats understandable, after all community-driven projects should
(mostly) be fun working on, they shouldn't get one overworked.

I really appreciate that you are progressing these, I was hoping that
someone with real jawin expertise would fill these out one day :op

Well I don't think I have reached that stage yet, but it was my hope to
extend the unittest-dll (CallCOMUnitTestD.dll) so that it could be used
for kind of testing the JTB stylesheets to. By running the JTB on the
type information in the DLL, and then use the generated code in the
unit-tests  - actually the test/org/jawin/IDualTestItf.java is a
slightly modified version of a generated file - so it already works
pretty well, but we need more native test-cases.

Best Regards
Morten

Subject: Re: Windows Registry Problem in Win98

Hi Ivan

First sorry for the slow answering-rate.

And then to your problem. I just looked in the source for the
Registry-class you are using, and Jawin is using the following native
Win32 API functions when your code is executed:
        RegOpenKeyW
and
        RegQueryValueExW

These are documented in the MSDN here:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/sysinfo/base/regopenkey.asp
and here:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/sysinfo/base/regqueryvalueex.asp

The versions Jawin is using are the so called Unicode versions (can be
seen by the prefix "W"). Unfortunately these functions are only
supported on Windows ME/95/98 in special cases:

"Windows Me/98/95:  RegQueryValueExW is supported by the Microsoft Layer
for Unicode. To use this, you must add certain files to your
application, as outlined in Microsoft Layer for Unicode on Windows
Me/98/95 Systems."
(quote from one of the links above).


As far as I know Jawin does not pt. support Ansi-strings (the opposite
to Unicode strings in the Win32 API) as required by Win98. So even if
you would write the Jawin marshalling code yourself (instead of using
the Registry class), I don't think it is possible to get it to run on
all Windows98 machines.

I don't know what your usage of Jawin are beside accessing the Windows
registry? But if you only need to access the registry, you could try to
look into the ice.jni.registry package:
http://www.trustice.com/java/jnireg/ although you should note that the
license is GPL, so if you are planning to use the software in a
closed-source commercial project you may have problems?

I assume that this bug:
http://sourceforge.net/tracker/index.php?func=detail&aid=972585&group_id=66397&atid=514369
has been opened by you, and is related to this mail?

Hope this helps you a little bit further
Best Regards
Morten Andersen
