Hello guys
Windows displays arabic digit shapes in arabic locale. I want to completely control digit shapes in my application. There are some settings in display language to disable this behavior, but I do not want to change them as It affects other applications, And even I do not know how to change them pragramatically.
I found no edit style to do this in the documentation of edit controls. any suggestions or links appreciated

Edit: I use visual studio 2010

I would expect that you could simply create a font and use it to draw the numbers in your application. (english locale on my pc)
I've seen apps written here display text in Japanese or Chinese, so don't forsee an issue with latin numerals in an app running in an arabic locale.

Here's an excerpt from the c++ code preview from ResEdit (visual resource creator).

HFONT hfont0 = CreateFont(-11, 0, 0, 0, 0, FALSE, FALSE, FALSE, 1, 0, 0, 0, 0, ("Ms Shell Dlg"));
HWND hwnd = CreateWindowEx(0, ("WndClass")0, ("Custom Char Generator for 1602 lcds"), WS_CAPTION | WS_VISIBLE | WS_POPUP | WS_SYSMENU, 0, 0, 311, 345, 0, 0, hInst, 0);
HWND hCtrl0_0 = CreateWindowEx(0, WC_STATIC, ("charPlaceHolder"), WS_VISIBLE | WS_CHILD | WS_GROUP | WS_BORDER | SS_LEFT, 0, 0, 117, 176, hwnd, (HMENU)IDC_LCD_CHAR_WND, hInst, 0);
SendMessage(hCtrl0_0, WM_SETFONT, (WPARAM), FALSE);

I'd suppose that you'd just create and assign the font in a similar manner.

It's a solution, but I do not want to restrict my application to use an special font. I want the users of my application to select thru the installed fonts freely.

No. If you see the later OP's comment, you will see it has nothing to do with fonts. See also my answer.

Thanks Sergei. I did see it and realize I'd erroneously thought the problem more complex that it now appears. Articulate and verbose as ever!

Thank you very much for your nice words.

No, Please not that the problem is with digit shapes, and not code points. please refer to the comments I put to Sergey's Solution. You were right with creating fonts that displays 0x660 thru 0x669 and 0x6F0 thru 0x6F9 as european digit shapes ('0' thru '9')

What is "Arabic locale"? Isn't it based on Unicode?

In Windows 7 -> regional and language setting -> Change system locale most people in my country set system locale to arabic. This causes digits 0x0030 thru 0x0039 print as national(arabic) digit shapes, rather than european(nominal) digit shapes. that is, unicode chars 0x0660 to 0x0669 or 0x06F0 thru 0x06F9 are shown. I want the edit control to display nominal digit shapes, independent of regional and language settings.

This has nothing to do with "digit shapes".

The "locale" cannot change digit shapes. Those are just different Unicode code points, so called "Eastern Arabic numerals", http://en.wikipedia.org/wiki/Eastern_Arabic_numerals[^].

In contrast, all the Western world uses "Arabic numerals" in its Western form, in different glyphs and code points which have been standardized in ASCII and other early standards:
http://en.wikipedia.org/wiki/Arabic_numerals[^].

See also: http://en.wikipedia.org/wiki/Glyphs_used_with_the_Hindu-Arabic_numeral_system[^].

Both Unicode subsets are supported by most modern OS by default. You can ignore the locate and use the code points you want in your applications. In any case, it absolutely irrelevant to the fonts you use.

I think you have not noticed my question exactly. my problem is digit shapes, not digits, and neither code points.
for example, if in regional and language setting we set system locale to arabic, and one
calles this code:
SetTextW( hwndControl, WM_SETTEXT, 0, L"01234567890" );
the control translates unicode chars 0x30 thru 0x39 to unicode chars 0x6F0 thru 0x6F9 and displays "۰۱۲۳۴۵۶۷۸۹" which are arabic DIGIT SHAPES. Of course if this code is executed:
wchar_t wszBuffer[11];
SendMessageW( hWnd, WM_GETTEXT, 11, (LPARAM)wszBuffer );
then the contents of wszBuffer will be the original unicode chars 0x30 thru 0x39.
I want to find a way to disable this behaviour in my application, and display european digit SHAPES, independently of regional and language setting.

Even then, you need to make system output correct code point. It has nothing to do with shapes. Shapes are already available.

I use only unicode, especially, numerals 0x30 thru 0x39. I have nothing to do with code points. what I need is this:
The edit control display '0123456789' when it's text buffer contains L"0123456789"
I want only to disable displaying numbers in national digit shapes in edit controls.

Sergey Alexandrovich Kryukov 11-Aug-13 23:42pm

You are confused. "Code points" is what is defined by Unicode: integer numbers corresponding to characters. Characters are understood as cultural entities, abstracted from their glyphs.

mr.abzadeh 11-Aug-13 15:21pm

I forgot to emphasis that system may change digit shapes. If we set system locale to arabic, and in the Additional settings set the native digits to national, then the edit control displays L"0123456789" as L"۰۱۲۳۴۵۶۷۸۹", and so does TextOut( hDC, left, top, L"0123456789", 10 ); this behavior can be changed by NADS(0X206E) and NODS(0x206F), or by passing ETO_NUMERICSLATIN to ExtTextOut function, but for edit controls, this does not work

Sergey Alexandrovich Kryukov 11-Aug-13 16:56pm

System does not actually change shapes, it modifies the output code.

How come earlier you found that it was a problem on your system and accepted the answer

mr.abzadeh 11-Aug-13 22:26pm

It was a different matter with ExtTextOut function. I wanted to display european digit shapes when I call ExtTextOut with passing ETO_NUMERICSLATIN to it, witch worked correctly. Now I am able to display European digit shapes in any device context hDC. My goal is to display European digit shapes in every window on my application. This will not be complete If I can not display european digit shapes in edit controls. edit controls paint their window internally, not giving me a chance to modify their digit shapes.
In this case, I need help to find a way displaying european digit shapes in edit controls. I do not have any problem with some function or code
Thanks for your nice helps and guides

Sergey Alexandrovich Kryukov 11-Aug-13 22:37pm

If this is your application, you can display everything in neutral culture which would give your all European numerals unless you explicitly output others...

mr.abzadeh 12-Aug-13 7:22am

How to display everything in neutral culture in C? Can you please offer me a link or material to study?

Sergey Alexandrovich Kryukov 12-Aug-13 11:31am

Please see this documentation chapter: http://msdn.microsoft.com/en-us/goglobal/bb688127.aspx#ene.

Pay attention for the section Number Formatting in Win32.

mr.abzadeh 17-Aug-13 19:39pm

Great. by SetLocaleInfo we can control number formating in a specific locale. but one thing remains: Because this function modifies values for all applications, it should only be called by the regional and language options functionality of Control Panel, or a similar utility. I want to modify values only to my application, and not to all applications.
