Any ideas?
Your problem has nothing to do with linker settings. The problem is that you need some header included before commctrl.h. What type of project is this MFC, ATL, Win32 API... ?

It's a WIN32 API project.

Do you have #include <windows.h> before #include <commctrl.h> ?

The first #include in the incriminated file concerns commctrl.h, as you can see below.
/**
* input.cpp
*
* Input module.
**/
#include <commctrl.h>
#include "input.h"
#include "inputvars.h"
#include "gamevars.h"
#include "layout.h"
#include "resource.h"
//.... rest of file

make sure you have included "winnt.h" or "wtypes.h" first. Does this help?

After including wtypes.h, I have no more errors. Thanks a lot guys.

You would think that the following bit of code would produce a 6-byte file:
wofstream f( "test.txt" ) ;
f << wstring( L"123" ) ;
But it doesn't. It produces a 3-byte file. A bit of experimentation indicates that the stream seems to be converting the wide characters to single-byte before writing it to the file. This also happens using Stlport (with their iostream library).
This seems just plain wrong. Anyone care to explain why it's like this?

Curse you for making me look at the VC 6 STL code this early in the morning. 
The fstream inserter eventually calls basic_filebuf::overflow(), which has this line:
fwrite(_Str->begin(), 1, _N, _File) The problem is that it writes 1 byte, when it should write sizeof(_E) [where _E is the template character type, wchar_t in this case].

I'm converting Awasu to Unicode. My life is over until further notice 
Actually, it's not quite that bad. Most of it is ready for Unicode but there are some core modules that I wrote years ago that need to be converted. Of course, *everything* uses them...

Yep. The odd thing is, Stlport does the same thing i.e. even when I use their iostreams instead of Microsoft's. They correctly process each character as 16-bit but then explicitly call codecvt to convert it 8-bit!
Which makes me wonder if this is what is supposed to happen. If this is a bug, it's a pretty obvious one and someone would've picked it up. Seems definitely wrong to me...

This is just fscked!!!
According to this guy[^]:
The standard *does not* provide a way to output (i.e.: to write on a disk file) a stream of wide characters. You can put wide characters into a wide stream but you will always obtain a file of "narrow" characters, obtained through a "degenerate conversion" as explictly specified in the standard.
Also here[^]:
On Win32, VC++ 6sp5, STLport the following test program produces the output 52 (0x34) instead of 4660 (0x1234). According to the standard, this behaviour is perfectly conformant.
int main()
{
wchar_t a = L'\x1234';
std::wofstream out("test.txt", std::ios::binary);
out << a;
out.close();
std::wifstream in("test.txt", std::ios::binary);
in >> a;
in.close();
std::cout << unsigned(a) << std::endl;
return 0;
}
(The second poster also makes the interesting point:
the ios::binary is required, because the I/O library could apply CRLF translation to a part of a two-byte character.
)
This makes no sense. What possible justification could there be to have wide streams output narrow?! The only thing I can think of is possible problems with sending wide data to the console, for example, but surely it would be preferable to hack wcout et.al. rather than crippling wide streams!

hi,
i need help from you guys again.
My program uses classes like CButtonST, AnyFormDialog, etc.
I am not blaming these classes, but i think my program is leaking memory. (found out using system monitor). when app closes, the memory is not released to the point where it was when launched.
now the question is how can i detect where in my application memory leaks? any free third party utilities ?
BTW, it leaks in ME, not in XP.
thanks for your reply.

thanks,
but as i said, it does'nt leak in XP. So i can't use this in my XP machine. It is leaking in ME only.
Also, i found out by trial and error that if i load the image from a file (~500KB) rather than a resource, it does'nt leak. Ofcourse i use DeleteObject() call at destruction when i load from resource.
regards
Hari Krishnan

The thing I was going to tell you that is handled differently between windows NT ( NT 4, 2K, XP) and Win 9x is resources.

It does not work on Win 9x (software verify)??

no, it does not work on 98.

I want to be able to pass an ado object interface pointer from VB to my COM dll. Is this possible. How would I go about doing such a thing.
Thanks
|
|
|
|
|
In theory, yes it is possible to pass pointers from and to COM DLL given that the DLL is in the program's address space.
As for practice, post some code. I am not familiar with VB. In general, one solution is to call a function in the DLL that takes a pointer to an interface as one parameter.

Hi,
I'm trying to pass a _RecordsetPtr to my ATL COM method as a parameter. Except I'm not too sure how to do it. How would I pass the interface as you described.
Thanks

Hello,
I am using CBitmaps for my bitmap objects. MSDN says that a bitmap loaded with the LoadBitmap member function will be freed automatically when the class is destructed:
You can use the CGdiObject::DeleteObject function to delete bitmap loaded by the
LoadBitmap function, or the CBitmap destructor will delete the object for you. Now I had a look into the MFC source files and found the following lines in the file Afxwin1.inl
_AFXWIN_INLINE CBitmap::~CBitmap()
{ }So it seems the destructor does simply nothing???
Will my bitmap be freed on destruction of the CBitmap class or not??
-Dominik
_outp(0x64, 0xAD);
and
__asm mov al, 0xAD __asm out 0x64, al
do the same... but what do they do??

It will. The bitmap gets destroyed in the destructor for CGdiObject, same as in other CGdiObject-derived classes.

Ah, this destructor reads
_AFXWIN_INLINE CGdiObject::~CGdiObject()
{ DeleteObject(); }
-Dominik
_outp(0x64, 0xAD);
and
__asm mov al, 0xAD __asm out 0x64, al
do the same... but what do they do??
