Connectorcpp segfault

[ATIDOT3]

Sup.

Got stupid error when i'm using the connector cpp library,

memcpy(res->sPcData[i].awchName, s2ws(this->res->getString("awchName")).c_str(), sizeof(wchar_t)* NTL_MAX_SIZE_CHAR_NAME_UNICODE);

the error come from:

this->res->getString("awchName")).c_str()

I don't know why when i'm trying to use .c_str() the program crash.

I checked my memory adress and it is not null.
My database containe the table and the field is not empty.

Here's the column propriety:

`awchName` varchar(14) NOT NULL DEFAULT '',
UNIQUE KEY `idx_username` (`awchName`)
) ENGINE=InnoDB AUTO_INCREMENT=5 DEFAULT CHARSET=utf8 COMMENT='Character System';
INSERT INTO `characters` VALUES ('1', '1', 'myfirstchar', '0', '0', '0', '0', '8', '4', '9', '5', '1', '0', '1', '0', '0', '0', '100', '100', 'osef', '0', '0', 'osef', '0');

You can't just take a UTF 8 String from the database and send it to the client, which requires UTF 16.

omg ..... thanks lol :banghead:



nop change nothing

the crash is not on the client, the crash is when i want to get my string from the database from the server.

try not with memcp

try like this

wcscpy_s(res->sPcData[i].awchName, NTL_MAX_SIZE_CHAR_NAME_UNICODE, s2ws(this->res->getString("awchName")).c_str() );

well for me I have this in charserver

memcpy(res->sPcData[i].awchName, s2ws(app->db->getString("CharName")).c_str(), sizeof(wchar_t)* NTL_MAX_SIZE_CHAR_NAME_UNICODE);

but works without problems

I think it's the how i insert my charname, i don't specify anything, not the way to get it maybe.



so just finished to remake my create system work fine but skill cannot get my name :?:



if i do:

std::cout << this->res->getString("awchName") << std::endl;

it's shozing me my character name, but if i do this:

std::cout << this->res->getString("awchName").c_str() << std::endl;

it is crshing :?:

[Daneos]

because you cant do .c_str() on wchar

 

[ATIDOT3]

it is not, it is a sql::String



this->res->getString("awchName") return a sql::String

this->res->getString("awchName").c_str() return a const char *

CREATE TABLE `characters` (
`charid` int(10) unsigned NOT NULL AUTO_INCREMENT COMMENT 'Identifier',
`AccountID` int(10) DEFAULT '0',
`awchName` varchar(16) DEFAULT '',
PRIMARY KEY (`charid`),
UNIQUE KEY `idx_username` (`awchName`)
) ENGINE=InnoDB AUTO_INCREMENT=9 DEFAULT CHARSET=utf16 COMMENT='Character System';

here is my new char database maybe i missed something ?

I just told you that your database is UTF 8 , and your client requires UTF 16.
Doesn't that tell you anything?
You can't display on client UTF 8. That's what I'm telling you.

 

[ATIDOT3]

CHARSET=utf16

What are you using as runstime library ?

/MT, /MD, /MDD, / MTD ?

i'm using (/MDd), and the linker

Ws2_32.lib
mysqlcppconn.lib
libmysql.lib
