I'm having a little problem when returning an object that has 2 string attributes, as soon as i create it, the string that has accented letters, for some reason transform in wear triangles.
I don't know if is a library, code or configuration problem.
I'm using visual basic .net
In the image you can see the problem.
Thanks.

I am working on an MBCS app using MFC. I am trying to support Asian languages. For the purposes of this discussion, we'll say I'm trying to support Chinese. I am able to support Pop up dialogs via MessageBoxW and Dialog SCREENs by pasting Chinese characters directly into the RC file. I can't get file menus to work using either resource view or editing the RC file directly. Whenever I type in ANY Asian character, the screen shows ???. One ? for each character. I have tried modifying the menu in C++ using ModifyMenuW. I get more question marks. Visual Studio shows everything working, and the RC file is unicode (UTF-16). I can't easily convert my project to unicode mode. Spanish, French, and German all works fine (one of the Essets in German doesn't work, but that isn't a show stopper). What should I try next?
Thanks in advance!
Well, the easy answer would be change the application to Unicode, but this is not always simple, or possible at all.
Concerning using Unicode in a MBCS application, some things are possible and some others not. For example, I have made a MBCS application displaying and editing translations of program strings (messages, menues etc) in a ListView control, however ListView does have a specific message to turn it to Unicode (LVM_SETUNICODEFORMAT) and support operations (see also CCM_SETUNICODEFORMAT). Menus aren't controls though, but they do have "wide" (Unicode) functions.
If you want to use Unicode in your application, there are some tests you need to make. Success is not guaranteeded, but you can at least draw some conclusions and determine whether what you want to do is possible.
Test1:
You mentioned trying ModifyMenuW(), but this will try to modify an existing menu. Instead, try InsertMenuW() or InsertMenuItemW(). Any unicode string should be displayed properly, so try not just Chinese, but other laguages too (eg Greek or Russian). And btw, I can't see how French works and German doesn't (they use the same codepage - West European). What's the system codepage of your test-machine?
Test2: (if the above has failed)
Try changing the whole menu (SetMenu()) with having a single (unicode) menu item as its root.
Test3: (if the above have failed)
Then you need to check whether the window containing the menu must be Unicode. Create a simple "Hello World" Win32 application, or find a sample, if Visual Studio does not do this for you (these basically register the window class, create the main window and start the message-loop) - you must add a menu too, using the "wide" version of the menu functions explicitly. If this doesn't work, try changing the code that creates the window to unicode. This way you will know whether you need a unicode window, to own the menu.
Please make these tests and let us know the results. I will further post if needed.
I can see special characters ąęį when I do form design on static text label:
These character are changed while running:
If I set these characters in programming way I have:
How can I ensure that the correct characters are displayed instead of question marks as shown in the screenshot above?
UPD:
My project is Multi-Byte. I found that in another computer I can see special characters. Why?
You need to use Unicode character set for this to work correctly, and my guess is that you're using MBCS character set now.
You could change it in the project properties. Refer to this screenshot:
Visual studio editor is fully Unicode, meaning it could display such special characters as you type when you're designing the dialog. However, if your application is not built with Unicode support, it won't be able to display thsoe characters when it runs. Thich is why you see the ??? replacing the Unicode text when you run the application.
If you get different results on different computers this is obviously due to differences in system settings.
The setting that controls this is called "Language for non-Unicode programs", and can be found under Control Panel, Language, Change date, time or number formats. Unfortunately it's a global setting (ie cannot be set per application or programmatically) and requires a re-boot.
Consider making your application Unicode, if possible (and meaningful cost- or effort-wise).
I'm trying to use nested view with DustJS (linkedin fork) with ExpressJS. While rendering the response system generates some escape chars in response. Which disturb the style and theme.
The same code renders fine as one view file, but when split code into two view files (one load as partial) than the problem arise.
Interesting thing is, it happens with two view engines I tried, the same issue, ECT and DustJS. Development on minimal components, Twitter Bootstrap 3.0 and express are additional component added so far.
My machine is running windows as operating system and development tool is visual studio. What could be reasons, has anyone find same trouble with these view engines?
View in Google Chrome Developer Tool.
Response-Text View
I tried to fiddle and tried to map the extra chars.
You have an UTF-8 BOM in one of the files you are using, usually in the first 3 bytes. Normally, a text editor will not show you these characters. Examine your used files with a hex editor (or write a script that examines those files for you) & store the offending file without that UTF-8 BOM, and configure all your editors to omit the BOM in future.
In addition to Wrikken's answer, if you are using Visual studio than it cab be fixed by advance save option.
I'm having a difficult time finding how to insert subscripts into a QString. I know it can be done with style sheets, but I can't really use a style sheet in places where I place a QString. I've tried HTML markup and UTF-8 and other unicode systems for substrings with no luck.
Hopefully someone has some more experience with this and can help out!
Depending on what characters you want to subscript, you may be able to use Unicode subscript characters without formatting.
That of course requires font and text rendering engine that support it. Don't know if Qt on your platform does.
A QString is just a string. If you're dealing with particular Unicode characters which should be subscript then fine, but otherwise what you seem to be trying to do makes no sense.
If you want to display a string with subscript formatting then you can use QTextEdit or other classes which support rich text display. You could do this with HTML markup or programatically using the relevant Qt classes. Try http://qt-project.org/doc/qt-4.8/richtext.html for more information.
I've got several large MFC applications here, and converting them into any other format is out of the question. We're expanding into other markets, and would like to make the apps work in other languages and cultures.
So far, I've found occasional references as to what to do with Visual C++ version 6, with one mention that later versions of MFC have additional relevant features. Searching MSDN gives me instructions on how to convert the apps to Unicode, which we already did. I found nothing on MSDN on how to make languages multilingual once they're in Unicode, only a few older things using Google, and one book about internationalization using VC++6. (We're using Visual Studio 2008 now, on XP and Vista.)
I make no claims for the strength of my Google-fu, and would be happy to be directed to things I've missed.
Is it reasonable to use the methods of VC++6, or should I use later features?
If I should use features later than that, where can I find some reference to them?
Is there something I should worry about other than setting the locale, converting all strings to resources, and duplicating resources in different languages?
I can find more things about .NET internationalization, but I'm inexperienced in .NET. What will I find there that's applicable to VC++ and MFC?
Edit: I just ran into difficulties trying to put Unicode strings into the String Table resource. (As far as I can tell, Unicode strings need to be entered into the .rc file with a text editor, in L"0x0034" form. I haven't found a resource editor way to do that.) Any tips on that? Any other resource I can use in VS2008 using VC++ and MFC?
Edit: Somebody on a Microsoft forum suggested that I open the offending .rc file in Notepad, and save it in Unicode. Unfortunately, this doesn't seem to fix the dialogs, although the stringtable seems to be working in Japanese.
There's a lot more than just translating "strings" to internationalize an application.
Most of your UI will need to be updated to take into account the different text lengths, and language orientation (thing Hebrew, Chinese, Arabic, ...)
Some images will also need to be changed to fit a different culture (unfortunately, I don't have an example for that), either the figurative is different or the colors do not fit local specifications.
We are using a tool like appTranslator to help us do the cosmetic localization (UI re-formatting) and use a professional technical translator for the strings.
You can also create a resource only dll
See How To Create Localized Resource DLLs for MFC Application for more details.
You can internationalize your application using the following ways.
After you converted the application to unicode (you already did) and all the strings should be loaded from String table.
For each language you need to change the string table and compile
One more way is to maintain a XML file which contains all the strings in the localized format. Load the xml and strings depending on the language.
Here's a CodeProject article of mine that describes very "coding-efficient" method to pull strings from the string table (required for translatable texts):
http://www.codeproject.com/KB/string/stringtable.aspx
Here's another class that help your app pick the right UI language. It also helps you create a language selection menu:
http://www.codeproject.com/KB/locale/LanguageMenu.aspx
Last but not least, appTranslator is a tool that helps you translate the UI of your app, detect what changes were made in resources since the last version, create translated exe or resource DLLs and much more:
