wchar_t under VS2005 and up
Message 1 in thread
I'm working on some code which interoperates with some other C++
libraries, one of which I did not have source code for until recently,
and I thus ran into an interesting quandary.
Is there a good reason (i.e., it doesn't currently build) that the build
settings for Qt in Visual Studio 2005 have /Zc:wchar_t- set? I could,
of course, try rebuilding it without that set by modifying the
qmake.conf, but before I try that I'm curious why that is, and if
there's any plan to change that.
Fortunately I have the source code for the other library now, so I can
rebuild it with /Zc:wchar_t- for the time being.

Maybe because of "breaking changes in VS2k5" against older versions:

Hello Gordon,
you can mix QStrings and wchar_t with <reinterpret_cast...
example // this is a win32 API example, OutputString is a QString...
MessageBox(0, reinterpret_cast<const wchar_t *>(OutputString.data()),
(LPCWSTR)"SQL-ERROR !", MB_OK | MB_ICONEXCLAMATION);
Regards,
Peter
