It's very simple to understand what this means:
For instance: NPC's name is: empty string : 100011009 empty string : 105011009
The first Empty string: empty string : 100011009 is the npc title: (E.g. Quest Broker)
Open SSMS (SQL Manager) and open your StringResource database
Scroll to the very bottom of the entries listed to the blank or NULL line (This line will have NULL in every column) click in the first empty box (name) and type: npc_title_100015 the second box (group) will be 0 the third will be the code so you will type in "100011009" and the final box will be the value or text you wish to be displayed so you would type in "Developer"
The second empty string: empty string : 105011009 is the npc name (E.g Syah)
Open SSMS (SQL Manager) and open your StringResource database
Scroll to the very bottom of the entries listed to the blank or NULL line (This line will have NULL in every column) click in the first empty box (name) and type: npc_name_100016 the second box (group) will be 0 the third box (code) type in "105011009" and the final box will be the value or text you wish to be displayed so you would type in "iSmokeDrow"
Now you have created the missing strings BUT and I mean BUTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTT these changes will not show until you import the updated strings into the client:
The following tools can do this: Xijezu's Rappelz Editor LITE, Pyroks RappelzED Lite, Raskims RDB Editor and Gr4ph0's String to Resource! (I will not provide specific instructions on these tools)
In this example after the strings have been created, open Pyroks RappelzED Lite and click the strings tab (Assuming you have configured the program to seek the correct database) / (Raskims Editor must also point to the proper Arcadia) then click 'File' in the upper left corner (RappelzED) and click 'Export' [WARNING! DO NOT CLICK SAVE!!!] save the new resource to wherever you like it's name will start with "!" (Raskims Editor click the drop down list and select "StringResource" then press "Load StringResource" once the data has been loaded press "Save" [NOTICE: The file will be saved under the working or CURRENT directory of the tool and the name of the resource will be incorrect for US or NA clients so you will need to use Pyroks Resource Dumper to provide the hash name of db_string.rdb]
Pop your new StringResource into the 'Resource' folder of your client and viola you now have updated strings both in database and in-game.
I WILL NOT ANSWER ANY FURTHER QUESTIONS REGARDING THIS! Have a great day and good luck.
