#63429 — VS2015

Microsoft Visual Studio Community 2015 RC
 Version 14.0.22823.1 D14REL
 Microsoft .NET Framework
 Version 4.6.00057

Installed Version: Community


Windows 8.1


When compiling with VS2013 I don't get an warning, but with VS2015 I get this warning.

>c:\program files (x86)\microsoft visual studio 14.0\vc\include\xlocale(654): warning C4302: 'type cast': truncation from 'const wchar_t *' to 'unsigned char'
1>  c:\program files (x86)\microsoft visual studio 14.0\vc\include\xlocale(2322): note: see reference to function template instantiation 'char std::_Maklocbyte<_Elem>(_Elem,const std::_Locinfo::_Cvtvec &)' being compiled

Now, I know what the problem is, VS2015 is very clear about it, but how can I trace the fault. Where in -my code- did I go wrong?

Since C does not have templates, you might start by asking in a group
related to the language you are using.

And when you post in a C++ group, be sure to show them the code that
causes the error.

He's asking "Where in -my code- did I go wrong?", so he doesn't know
which code caused the error.

If the above message list is complete, I see his point - the only line
numbers given are for the xlocale file, which is presumably not his
code. There should be an error message identifing the line on which an
attempt was made to instantiate that template with types that triggered
this warning. There doesn't seem to be any such message (assuming the
message list is complete).

Problem is that it is probably bug in the compiler.

Yes, your *first* mistake was using a compiler built by Microsoft!!!

It generates better code than gcc, the only compiler that is better in 
the speed of the generated code is Intel's.

There are some people against microsoft for ideological reasons. I 
understand them but they become quite blind sometimes. That is called:

EXAGGERATING

Mind you, only this week I was using GetWindowLongPtr and I thought to myself that only Microsoft would make a compiler where you can get rid of a warning by casting the result of a function call to the type the funtion returns. GetWindowLongPtr returns a LONG_PTR (according to MSDN) but VC++ complains about

ppp = (int *) GetWindowLongPtr(hWnd, GWL_STYLE);

(converting to a greater size)

while allowing

ppp = (int *) (LONG_PTR) GetWindowLongPtr(hWnd, GWL_STYLE);

with no warning. Of course, one might expect GetWindowLongPtr to return an actual pointer...

Your mesage points to a very small flaw of the compiler.

I didn't say that it was PERFECT, i.e. that there are no bugs in it.

I just said that the generated code is better than gcc's and better than 
all other compilers i know of but Intel's.

Now, it wouldn't be out of character for Mickey$oft to demand that you
pervert your code like that, but a thought _does_ occur...

Are you sure you #included the relevant header? This sounds as if the
compiler thinks GetWindowLongPtr() _doesn't_ return a LONG_PTR.

You have the source code. We don't. So you have us at a disadvantage.

If you're programming in C (and, judging from what you've written so 
far, that seems rather unlikely), why not post the source code that's 
causing problems and let us take a look?

If you're programming in some other language (C++, C#, .Net, or whatever 
it is), you might want to try finding a newsgroup that's a closer match 
to your language choice).
