Load Font directly from Font-File? - C / C++ / MFC Discussion Boards

I'm sorry to diverge from your original question a bit, but I think you may be getting caught in a bit of an optimization trap. If you are worried about performace, I would address your use of strings for mathematical calculations long before worrying about whether a static, inline, friend, or global function is faster. I can't say I have ever seen a bignum library work with strings in the way you have shown. Each takes a string representation of a number, converts it to binary form, and uses that binary form for calculations. For examples, see the MIRACL[^] and Crypto++[^] libraries. If you need help with algorithms for bignum arithmetic, check out Knuth's Seminumerical Algorithms[^]

that's quite good... but - just a guess - do you know any floating point libraries that can accept numbers bigger than a long double can ?

The only one I know of personally is the GNU MP Bignum Library[^]. It has arbitrary-precision floating point arithmetic capability thanks to the MPFR library[^]. I haven't used either one myself, but if you're interested in the algorithms behind it I believe the Knuth book discusses some and the MPFR page has some links.

adding bitmaps to menu items

I need to add a bitmap to menu item, so I've done this but it doesnt work:

CMenu Menu;
Menu.LoadMenu(IDR_MAINFRAME);
DWORD size = GetMenuCheckMarkDimensions();
WORD width = LOWORD(size);
WORD high = HIWORD(size);
CBitmap Bmp;
Bmp.LoadBitmap(IDB_BITMAP_NEW_P);
Menu.SetMenuItemBitmaps(ID_NEW_PROJECT,MF_BYCOMMAND, &Bmp, &Bmp );

Help anyone? Sniff | :^)

THANKS

Hi.
Is it possible to load a font directly from a font-file (*.ttf etc in an ordinary path) without registring the file in the system font tables (registry etc)?

thanks for the help, and good luck for your own projects

Thanks Chris
but see
-Font files must be in the SYSTEM subdirectory of the WINDOWS directory to be used by the AddFontResource function.
-The CreateScalableFontResource function is used to install TrueType fonts
-The EnumFontFamiliesEx function enumerates all fonts in the system that match the font characteristics..

I want to load a Font directly for a *.ttf or *.fon file. This file can be everywhere ( CD..)

Never the less thank you very much for trying to help me

So just copy the .fon or .ttf file(s) to the Fonts folder before calling AddFontResource().

Hello samira!
It isn't possible. because a exe file must be in a path of disk for execution ,
and don't execute a file that there isn't in disk.
good luck. Cool | :cool:

VS NET. 2003 strange characters in MFC project?

What is wrong with my just installed licensed VS NET. 2003, while creating a project it puts default files and configurations etc. and I get this strange encoding for 'MFC application' project only:

just example from default created some MFC application project

BOOL Ctest2App::InitInstance()
{
// °І¦pАіҐОµ{¦Ўёк°TІMіж«ь©wЁПҐО ComCtl32.dll 6.0 (§t) ҐH«бЄ©Ґ»

{

return FALSE;
}
AfxEnableControlContainer();

While there is no such a problem with other types of projects, only with MFC application one?

A bug means that it uses the Taiwanese character set! When you run the MFC AppWizard make surte you change the "resources" language and it will be fine.
