Window Application Development!

Posted on 2002-04-12

In developing a window application which needs to support mutli-lanuage, what factors need to be considered?

I know something called Unicode, code page, locale, etc?

Can anyone give me a guideline in developing a mutli-language window application?

In fact, my application may run at English OS and Simplified Chinese OS!

Thank you!

Indeed the locale has something to do with it. Locale itself will tell you for example the dateformat. It is a number which you can use to find out the current settings of the users. The multilingual part you do different. You would use resources for that.

For example in Visual C++ you have resources like a Menu, icon etc. But you can also add strings in there. If you also combine them with the locale you have a multilingual windows program.

For example:
locale 1033 is English (United States)

your resource could look like:
name - locale - value
FILEMENU - 1033 - "&File"

In your program you then find out the locale id and grab it from the resource together with the requested name.

You can also use a database for this purpose, it's just whatever you want!

Most of this can all be handled at install time, just selecting the MS options (other than default). Keep text simple, and as text, defer the fancy stuff. Visit existing multi-lingual webpages for contrast with needs, and to develop interests.

Hi all,

If I am using VB/VC++ 6.0 as my developing tools,
ususally, what extra must be done at my application instead of developing a native applicaiton which work for only 1 language?

For example, define using Unicode, get the locale setting?

Can anyone give me a brife example?

I think you might find this web site helpful:

Its somewhat difficult to briefly answer your question. I oversaw the development of an application which also supported English and the Simplified Chinese OS. I also had to support many others.

Some of the issues I ran into were for example:
Unicode was not fully supported under Win95, yet I was trying to write something that would run on any Win32 platform. I also was using third party tools which also had to be able to support mulilanguage development.

Any other questions?

I have the same issue with an app I am developing.  UNICODE support is a definite.  For resources, we place all of them into a specific resource dll.  So when a "language manager" determines the right language it will load the correct resource dll.
You can place just strings in there and have all of your dialogs load the strings as it's created, or put all of your resources into it.

Since we contract our language translations it is easier if they get just a resource script and use it for translation.  Plus by placing the dialogs in the same resource dll we can instruct them to resize them if the translation strings are too long.  

I hope this helps
