I decided to make an app with multiple languages in such a way: i left all resources (menus, buttons, labels, etc.) without captions. And I created some files with text for all these resources in different languages. when initializing my app, i do WM_SETTEXT for everything. Is this a good way? I think it will make the initialization of my app much longer. But it also reduces the size of executable, what is good. Or maybe there are any more efficient ways to make a multiple language support for an application?

I think that one good solution for such case would be XML. Just define yourself a file specification eg.:
Code:
<translation>
  <language>Polish</language>
  <version>1.0</version>
  <keyword="Add">Dodaj</keyword>
  <keyword="Subtract">Odejmij</keyword>
</translation>
    

Such a solution is imho good, when you want other people to create translations to their own language, but as you see it takes some place and reading such a thing is slower than reading binary format.

Another way of doing this may look like that:
Code:
1=Dodaj
2=Odejmij
    

And such a file would be named like 'polish.lng' or something like that

And the last solution that comes to my mind is using resources. You can define for example that your program would have n different strings. Than just define somewhere in program:
Code:
MAX_STRINGS = 100 ; this is the 'n'

_ADD = 1
_SUB = 2
...
POLISH = 1
ENGLISH = 2
...

        ; user picked polish language
        mov     eax, POLISH*MAX_STRINGS
        ; let's read a string for 'add'
        add     eax, _ADD
        invoke  LoadString, [hInstance], eax, ptrBuffer, sizeof.ptrBuffer

        ; user picked english language
        mov     eax, POLISH*MAX_STRINGS
        ; let's read a string for 'add'
        add     eax, _ADD
        invoke  LoadString, [hInstance], eax, ptrBuffer, sizeof.ptrBuffer
    

And in resource definition:
Code:
#define MAX_STRINGS 100

#define POLISH 1
#define ENGLISH 2

#define _ADD 1
#define _SUB 2

STRINGTABLE BEGIN
  ((POLISH*MAX_STRINGS)+_ADD), "Dodaj"
  ((POLISH*MAX_STRINGS)+_SUB), "Odejmij"
END
    


Beware! All of these examples were written ad hoc so I don't assure they'll work in a way they're shown here

EDIT: I forgot to say, that the last solution will take a lot of place, as all strings in resources are saved in utf-16, so every single chatracter will take 2 bytes
