Localizing strings on Symbian C++ apps

Comments

This article had explained about the localisation strings here in if we want to make a application for the diffrent langagues here langauges is not like progarmming language langunage is nothing but english ,spanish .......like that so these are used to do that in this artilce they had explained more clearly about localisation of strings

This artcle help to the fresh developers who started development in symbian c++ newly --Narendrachinni 04:54, 17 September 2009 (UTC)

Overview

This code example describes how to localize the text strings of an application.

This snippet can be self-signed.

Steps

1. Create the data\[app].rls file.

2. Write the localization information into it:

#ifdef LANGUAGE_SC          // Default: UK English
 
#include "app_loc.l01"
 
#elif defined LANGUAGE_01   // UK English
 
#include "app_loc.l01"
 
#elif defined LANGUAGE_09   // Finnish
 
#include "app_loc.l09"
 
#endif

3. Add the localization strings into the appropriate files (for example, data\[app]_loc.l01 and data\[app]_loc.l09):

// Strings in data\[app]_loc.l01:
 
rls_string STRING_r_localized_text "Localized text."
rls_string STRING_r_localized_string_param "Localized string parameter: %U."
rls_string STRING_r_localized_number_param "Localized number parameter: %N."

// Strings in data\[app]_loc.l09:
 
rls_string STRING_r_localized_text "Kotoistettu teksti."
rls_string STRING_r_localized_string_param "Kotoistettu merkkijonoparametri: %U."
rls_string STRING_r_localized_number_param "Kotoistettu numeroparametri: %N."

4. Create resources from localized strings in data\[app].rss:

RESOURCE TBUF r_localized_text { buf=STRING_r_localized_text; }
RESOURCE TBUF r_localized_string_param { buf=STRING_r_localized_string_param; }
RESOURCE TBUF r_localized_number_param { buf=STRING_r_localized_number_param; }

5. Use StringLoader to load and format resource strings:

#include <stringloader.h>

HBufC* resLocalizedText = StringLoader::LoadLC(R_LOCALIZED_TEXT);
// Use resLocalizedText
CleanupStack::PopAndDestroy(resLocalizedText);

_LIT(KString, "A string");
HBufC* resLocalizedStringParam = StringLoader::LoadLC(R_LOCALIZED_STRING_PARAM, KString);
// Use resLocalizedStringParam
CleanupStack::PopAndDestroy(resLocalizedStringParam);

TInt number = 34;
HBufC* resLocalizedNumberParam = StringLoader::LoadLC(R_LOCALIZED_NUMBER_PARAM, number);
// Use resLocalizedNumberParam
CleanupStack::PopAndDestroy(resLocalizedNumberParam);

6. Insert the LANG attribute into the group\[app].mmp file:

LANG SC 01 09
