I try to build latest dwt samples from source with installed dmd
snapshot 0.6.2 and DMC (for optlink): compiling is ok, but linking
fails: symbol undefined: _IsHungAppWindow and _GetSystemDefaultUILanguage.

What to do?

Thanks for trying DWT.

Thanks, Frank.

I was wondering what does "import lib zip file" mean for some time, that is not obvious from faq page... When I downloaded zip with win libs from http://www.dsource.org/projects/dwt/wiki/ImportLibraries, the dsss build result was the same. The real reason was simple: optlink doesn't about dmd/lib!

"dsss build --libdir=C:\dmd\dmd\lib" worked.

I get "Object.Exception: access violation" at launch of text editor sample, custom control sample and while pressing any boxes/checkers in control sample...

Do you use a compiler known to work?

Yes, 1.031 from dmd snapshot 0.6.2 - my projects compile and run successfully.

I also have a problem that dsss build "fall asleep" during build process, every time at different sample. Maybe it's Vista's DEP, I'll check it now.

Hm, yesterday in IRC a user called "krishna" had exactly the same problem on Vista too.
If I "see" him again, i will try to find out what was the exact solution.

using ddbg for text editor sample:

Can you please repeat the same with recompile and debug symbols enabled?
Option -g
Then there would be line numbers. The installListenersMethod is kind of long.
When the debugger then stopps, you can use the "us" command to get a stacktrace which is also interresting.

You have used once the DMD 1.029/30, haven't you?
Have you recompiled the DD-dwt.lib after upgrading?
This error would match this problem.
