e.g.
#define ANY_ID_1 'id' // gives the warning under gcc mac
#define ANY_ID_2 ' id' // gives the same byteorder like 'id'
#define ANY_ID_3 '\0\0id' // has the wrong byteorder
i use the defines as longs ...
cheers

the compiler is probably treating '\40\40id' as a numeric literal (which causes the machine's byte-order rules for numerics to get involved).
it probably sees ' id' as a string literal (even though you shouldn't put multiple characters inside single quotes), and ends up doing something like:
char *p = " id";
long f = *(long*)p;

hmmm ... strange things happens ...
i tried this one here ...
char *p = "\0\0id";
long f = *(long*)p;
if running this code f results in 0x64690000 ... that's exactly the same what the compiler generates with the constant '\0\0id' .. and that's swapped compared to 'id' which results in 0x00006964 ?!?!?!?!
this is one of the days where i don't understand compilers  ... i want that the compiler generates the same constant when i write 'id' and '\0\0id' because this is obviously the same (for me!)
cheers

how about:
long f = (0x00) << 24 | (0x00 << 16) | (0x69 << 8) | 0x64;
?

that would work but make a lot of work at another place in the program because i use the includefiles are parsed with an own scripting language that understands only 'xxxx' and numbers
thanks for the suggestion ...

This is just a shot into the blue, but isn't Unicode basically not a system type? Like, int would be "swapped" on little endian/big endian" but unicode would be the exact same binary pattern?
I remember being lectured on something like that, but I might be way off here.
Cheers,
Sebastian

How to create a new window(child window) from menu list...and also from toolbar?
|
|
|
|
|
I did'nt get your question..Please add more information
|
|
|
|
|
what is a window ?
i give you the example for a new dialog box. if you want something else, make the conversion.
when you click on a toolbar button, on on a menu item, handle the WM_COMMAND event that is thrown, and overload it :
void OnSClickMenuAbout() {
CAboutDlg dlg;
dlg.DoModal();
}
(here i consider you open the "About" DialogBox on clicking its item in the menu...)

i only gave an example...
the
CAboutDlg dlg; line can be replaced with something like :
CChildFrame frm(this); where this is the parent for instance...
i hope the guy can search for infos by himself, and not waiting for everything well done and well written, until he just have to copy/paste the solution in his code...

have you heard about compilers?
I think there are compilers in linux too and probably the best one (ppl say that) its called gcc.

just a correction.
gcc knows C.
g++ know C++.
moreover, this is maybe the best thing to do to recompile the project. however, if the program is designed for windows specific libraries, they won't work under linux (and won't even compile - for e.g. MFC...)

just a nitpick:
gcc[^]: "The GNU Compiler Collection is a full-featured ANSI C compiler with support for K&R C, as well as C++, Objective C, Java, and Fortran."
g++[^] : "g++ is the traditional nickname of GNU C++, a freely redistributable C++ compiler. It is part of gcc, the GNU compiler suite, and is currently part of that distribution."

If your program is created with plain C++ without the support of any MS specific libraries, then it should compile fine with Linux compilers. Linux has several editors as well, I use Kate for C++ Programming. You have to compile and run program from shell (similar to command-prompt in Windows).
And Yes, if you are using any Windows APIs etc, you will have to replace those with Linux specific things. C++ is not platform independent, therefore, you have to tweak your program to run it on Linux. Start it, You will be through. Its not that difficult.

Which makes no sense at all. Machines don't care what high-level language you used to create the application. As long as the binary matches the target platform, you're good to go. Now if you wanted to compile C++ code on a Linux box, that's a different animal altogether.

I developed a VC++ application and now I need to support UNICODE to show Hebrew strings into a CListCtrl. I added the declaration:
#define _UNICODE
but now I obtain several error during the compilation process:
error C2664: 'int ATL::CStringT<basetype,stringtraits>::Find(ATL::CSimpleStringT<basetype,t_bmfcdll>::XCHAR,int) throw() const' : cannot convert parameter 1 from 'const char [11]' to 'ATL::CSimpleStringT<basetype,t_bmfcdll>::XCHAR'
with
[
BaseType=wchar_t,
StringTraits=StrTraitMFC_DLL<wchar_t>,
t_bMFCDLL=true
]
and
[
BaseType=wchar_t,
t_bMFCDLL=true
]
This conversion requires a reinterpret_cast, a C-style cast or function-style cast
This is because I used string constants without the _T("..."); prefix.
In my application there are several strings without _T prefix so I wanted to know if exist a workaround to use UNICODE without the intoruduction of _T prefix.
Remember that I need to display Hebrew strings.
Thank you

I think you have to replace all strings without _T(...) with _T(...), it is one good way to avoid any future problems too.
Actually its a good practice for UNICODE aware program to always include the strings in _T() macro.
