If you use the separate DLLs for each language, call GetUserDefaultLangID() to obtain the user language, then LoadLibrary("Appropriate name").

If you placed all languages into the same dll, the Windows must choose appropriate resources itself.
Alternatively, you can use FindResourceEx/LoadResource/LockResource to select different language resources.

Borland is not really "resource dll" friendly - one of the primary reasons I moved to VC++ about a year ago.

If you have VC++ you can place all resources into one DLL and make it work - with BC++ you must have several DLL's - one for each language

The following function allocates a resource buffer - then retrieves the string associated with the value passed

//=========================================================================
// Name:    GetBuff                                                        
// Purpose: This is the buffer allocator.  Each time it's called, it returns
//                  a pointer to a 256-byte temporary buffer.  As a convenience to
//                  the caller, the first byte of the buffer is set to zero.
//=========================================================================

LPSTR PASCAL GetBuff (void)
{
    typedef char Buffer [MAXSTRSIZE];      // define our string buffer

    LPSTR p;
    HANDLE hBuff;
    static int BufNum = 0;
    static Buffer far * szBuffer = NULL;

    // If this is the first call, then allocate the buffer

    if (szBuffer == NULL)
    {
      hBuff = GlobalAlloc (GHND, sizeof (Buffer) * NUMBUFFERS);
      if (hBuff == NULL);  // Now's the time to panic !
      szBuffer = (Buffer far *) GlobalLock (hBuff);
    }

    p = szBuffer [BufNum++];
    if (BufNum >= NUMBUFFERS) BufNum = 0;
    *p = '\0';
    return p;
}


//=========================================================================
// Name:    GetResStr
// Purpose: This new version of GetResStr uses GetBuff to get a temporary
//          buffer for holding the returned string.
//=========================================================================

LPSTR PASCAL GetResStr (WORD id)
{
    LPSTR p;
    LoadString (hInstance, id, p = GetBuff(), MAXSTRSIZE - 1);
    return p;
}

Example :
/* Set the WIndow Title */
SetWindowText(hDlg, GetResStr (IDS_LD_TITLE));

Let me know if you need more

>>Borland is not really "resource dll" >>friendly

I shouldn't say that.
I have not met any such problem when I used the Borland compiler before.
I moved to VCC by another reasons.

What I really meant to say was that in  VC++ you can add strings which are only loaded dependant upon the country setting you choose - in BC++ (5.01) you cant do this - BC++ wont compile several different languages in the same resource file.

No problem, at least with my Borland 5.02

LANGUAGE LANG_GERMAN, LANG_NEUTRAL
STRINGTABLE
{
 1,"Ya"
}
LANGUAGE LANG_ENGLISH, LANG_NEUTRAL
STRINGTABLE
{
 1,"Yes"
}

In VC++ you use afxSetResourceHandler with the HANDLE you got from the LoadLibrary and everything is ok. Is there an equivavlent api to that in Borland ?

I am not good expert in MFC , but seems
me that TModule class make all functions,
as afxSetResourceHandler :
example from my project:
TModule  resModule = new TModule(szNameDll);
....
      cdBitmap[nIcon1].hGraph = resModule->LoadBitmap(IDB_SHPS + ind);
...
Or
  return resModule->LoadString(code,buff, 80) - 1;
....
Class TModule encapsuleted all Functions
for work with Resoureces. See BC Doc and
BorlandC examples for more Information.

Gilad, may be i don't understand something? You ask about Api/Class for
working with Resource Dll, right?
Now you ask something other.
Roule of  EE: only one question in you Q! And, sorry, what wrong in my reply?
TModule does not works? Or something
else?

It was the same question. I didn't check your sujestion, cause I read about the other idea (with the wizard), but I guess you may be right and since you may be right I assume you deserve the points so send the form again.

Ok, i risk to reply again.
About wisard: in BC you can use AppExpert: in File|New|Project|AppExpert
You can make good project, but it is not the wisard, as in VC, as i know.
Simple you have sceleton with some functions(you chouse them) and after that you insert manually you functionality.For example, TModule for
working with Resource Dll.
