Hello Johannes,

If you are using 32 bit you can use loadstring and put the text in only
one resource file in more than one language. The OS looks what is the
primary language selected in the international settings and adapts
automatically the output to Loadstring.

For more info, let me know.

Sorry I didnot read your message well.

The solution that I use in 16 bit is almost the same as the 32 bit
version and allows easy porting.

Use string tables and loadstring. Use also a global variable for the
language like:

#define ENGLISH 5000
#define DUTCH 10000
etc...

if (!lstrcmp(szLng,"UK"))
LngOffset = ENGLISH;
else if (!lstrcmp(szLng,"NL"))
LngOffset = DUTCH;
else if (!lstrcmp(szLng,"GER"))
LngOffset = GERMAN;
else if (!lstrcmp(szLng,"SWE"))
LngOffset = SWEDISH;
else
LngOffset = ENGLISH;

and instead of Loadstring use XLoadstring which I defined as

LPSTR TLanguage::XLoadString(HINSTANCE hInstance,int StringID)
{
static char String[255];

LoadString(hInstance,StringID+LngOffset,String,255);

return (LPSTR) String;
}

in your resource file it should look like

STRINGTABLE
{
ENGLISH + IDS_PASSWDWNDTEXT, "AIRMAIL PASSWORD"
ENGLISH + IDS_PASSWDSTAT, "Password"

ENGLISH + IDS_NO_PERMISSION, "You have no access to this
function,\nDo you want to login now?"
ENGLISH + IDS_LOGINWINDOWTEXT, "LOGIN"
ENGLISH + IDS_USERNAME, "Username:"
ENGLISH + IDS_PASSWORD, "Password:"

DUTCH + IDS_PASSWDWNDTEXT, "AIRMAIL PASWOORD"
DUTCH + IDS_PASSWDSTAT, "Paswoord"

DUTCH + IDS_NO_PERMISSION, "U heeft geen toegang tot deze
functie,\nWilt u onder een andere naam inloggen?"
DUTCH + IDS_LOGINWINDOWTEXT, "LOGIN"
DUTCH + IDS_USERNAME, "Gebruikersnaam:"
DUTCH + IDS_PASSWORD, "Password:"

GERMAN + IDS_PASSWDWNDTEXT, "AIRMAIL PASSWORD"
GERMAN + IDS_PASSWDSTAT, "Password"

GERMAN + IDS_NO_PERMISSION, "You have no access to this
function,\nDo you want to login now?"
GERMAN + IDS_LOGINWINDOWTEXT, "LOGIN"
GERMAN + IDS_USERNAME, "Username:"
GERMAN + IDS_PASSWORD, "Password:"

SWEDISH + IDS_PASSWDWNDTEXT, "AIRMAIL PASSWORD"
SWEDISH + IDS_PASSWDSTAT, "Password"

SWEDISH + IDS_NO_PERMISSION, "You have no access to this
function,\nDo you want to login now?"
SWEDISH + IDS_LOGINWINDOWTEXT, "LOGIN"
SWEDISH + IDS_USERNAME, "Username:"
SWEDISH + IDS_PASSWORD, "Password:"

}

Get the message? If you change the language offset it will just take the
strings of the selected language at runtime. For changing text in
dialogs etc show them in TDialog::SetupWindow().
