I have all strings in a mySQL table and then use a Perl script to create .rc files for the different languages.
I can than add one of those .rc files to my resource includes for a particular language.
My problem now is that I want a single exe without satellite DLLs for the different languages. That doesn't seem to be possible, because each string id can only be in one string table and it is also not possible to select a particular string table.
My idea now was to add XML files with the strings to my resources and to overload LoadString. But I'm not sure if that also works with unicows on Win9x?
Are there any other options to support multiple languages from a single exe?
Thanks André

One possibility is to use ranges. Thus, all English strings could zero based, all of language 2 could start at 10,000; language 3, 20,000 and so forth. This is limiting, but can be done.
Anyone who thinks he has a better idea of what's good for people than people do is a swine.

Unfortunately that doesn't work, at least not without a custom LoadString function. LoadString looks in the table for an id (number) and then copies the string from the table to the buffer. Therefore it would always load the string of the language without an offset.

That goes without saying.

Results in a warning C4273: 'LoadStringW' : inconsistent dll linkage. dllexport assumed.
And my own function never gets called

I wouldn't overload LoadString directly. Rather I'd add a function like MyLoadString which would have smarts about what the current language is and all that. The advantage of this is that it could account for language neutral strings and whether satellite DLLs are used or not--in other words, the rest of your code wouldn't care where the strings are or how they are organized. For CString, you could have an overloaded version of MyLoadString that took a reference to a CString object and the ID (or you could always return a CString--there are many possibilities.)

That doesn't work, MFC as well as the UI toolkit calls LoadString for menus/toolbars

There is an article on CP somewhere that discusses this problem exactly. I'm having trouble finding it at the moment, but from what I remember about the article, each DLL was basically nothing more than a resource holder (specifically for string tables in different languages). The author added a menu item allowing the user to change the default language and the next time the program was run, it would load the dll for that language instead. If you do a little searching around CP, you can probably find it.

Thanks, but as already said I don't want to use satellite DLLs, I prefer to have a single exe to distribute.

Then your only hope is to put every language you want to support into your string table use an offset when loading strings. That is, every call to LoadString would look something like this:
CString str("");<br />
str.LoadString(IDS_MYSTRING + (iCurrentLanguage * ms_Offset));
This isn't very flexible since you have to make sure that a given string is offset exactly for each language.

It's a source files mamangement system.

It manages source files:
1) Providing repository
2) Coordinating development in a team environment
3) Easying source code backup
4) Automating release configuration
5) etc.

For Windows, Visual Studio Enterprise Edition provides "Visual Safe Source" tool. For free downloads, google "cvs for windows". For Linux, check out GNU websites for GNU CVS.
Best,

Try having a look at the first few chapters of Version Control with
Subversion[^], which talks about the Subversion[^] product.
Subversion is a pretty nice SCM/RCS product, BTW...

I am writing an expression evaluator, so I have come across the following head-scratcher:
We all know that for every type in the C++ world, we are able to declare either an actual instance of that type, or a pointer to that type. C++ natively supports up to two levels of indirection, if I am correct.
So, is the level of indirection an attribute of the type, or an attribute of the symbol that represents the instance of the type?
In other words, are there three different native types called:
char
pointer-to-char
pointer-to-pointer-to-char
OR is there really only one type
char
and the level of indirection is an attribute that belongs to the specific symbol being declared?
