Perhaps I'm missing something, but the RichEditBox control already supports right-to-left writing. It uses a standard Windows rich edit box, which has supported right-to-left scripts for many years. All the standard Windows controls support right-to-left scripts. See the attached file for a screen shot of the current Rich Edit Demo with Arabic and Hebrew text.

Mr. Carmody;

no, no, please ! It's me who missed something

This is very interesting and exactly is that I'm searching

Could you please add this feature, by a sign (button, menu item etc) for changing writing direction to our famous RichEdit Demo ?

Thanks in advance

There is no need to add anything. This feature is already in the Rich Edit Demo. If you copy right-to-left text into the document, it will display properly, and you can edit it as you expect. That's what I did to get the image I posted in my last message. The cursor automatically goes from right to left when it encounters text in a right-to-left script. This is true of almost all controls in Windows.

But you cannot TYPE such text. Are you asking for a feature that would let you type this text? Do you want to press Latin keys and get Arabic or Hebrew output? That is a significant change. I have done it for Devanagari, the alphabet of Sanskrit and Hindi. I think it would not be too hard to make a similar program for Arabic or Hebrew. I don't know Arabic or Hebrew, so it would not be good for me to attempt this.

My Devanagari program is called AksharaPad and is at http://kevincarmody.com/software/aksharapad.html. It's based on my revised version of the HMG Rich Edit Demo, which is at http://kevincarmody.com/hmg/SAMPLES/Con ... chEditBox/.

OK, understood, thanks.

Yes; for me, this is essential.

Do you want to press Latin keys and get Arabic or Hebrew output?

The "virtual keyboard" of Windows is more practical. After set a language, physical keyboard too works for characters of selected language.

OK, understood, thanks. I think it will be hard, because in Arabic shape of each character will change depending on position of that character in the word : beginning, inside and the end.

Again thanks, I will look and work to understand your work.

Thanks again

The virtual keyboard should let you type into any Windows control. So you can use it with any Windows software, including the Rich Edit Demo as it is now.

I think it will be hard, because in Arabic shape of each character will change depending on position of that character in the word : beginning, inside and the end.

It may not be as hard as you think. Devanagari has a a similar issue with combining consonants, but Unicode takes most of the pain out of it. Unicode uses "abstract characters" which can change shape depending on the characters around them. For each Latin keystroke, you tell the program which Unicode Arabic character or characters to insert into the document, and the Unicode rendering engine in Windows takes care of selecting the right shape out of the current font.

This assumes you are NOT using a virtual keyboard, but just the ordinary Latin keyboard. This approach is best if you only type Arabic occasionally. You can also decide for yourself exactly how the program will respond to each Latin character.

How Unicode works with Arabic is described in detail in Chapter 9 of the Unicode manual, which you can download from the Unicode web site at http://www.unicode.org/versions/Unicode8.0.0/.
