Problem with own class

[mcco]

I have the next piece of code:

vector<ChatSession> ssid;
 
void SessionCreator( void *ch ) 
{
    vector<string> users;
 
       ...
       ...
       ...
 
    ChatSession cs;
 
    // put chat session objects in vector array
    for (int i = 0; i < (int)users.size(); i++)
    {
        const char *t = users[i].data();
        char t2[30]; memcpy(t2, t, strlen(t));
        cs = new ChatSession(*t2);
        ssid.push_back(cs);
    }
 
    // Terminate myself
    _endthread();
}

program.h:

class ChatSession
    {
    private:
        char ChatID[100];
        char Name[30];
        char Message[1024];
        char newMsg[1024];
        bool CanSend;
    public:
        ChatSession();
        ChatSession(char *nickname);
        ~ChatSession();
        void SetChatID(char* id);
        void Send();
        char *getName();
        bool ready();
    };
    ...
    ...
    ...
 
extern vector<ChatSession> ssid;
 

VC++ throws angry error error at me:

Line: cs = new ChatSession(*t2);

Error C2664: 'ChatSession::ChatSession(char *)' : cannot convert parameter 1 from 'char' to 'char *'

Please help.

remove the * in *t2, you are deferencing the pointer.

Also where you populate the array t2 you have made some mistakes.

You call data but that returns an array wthout a zero terminator so you can not call strlen on it. If you want the zero terminator copied then call string::c_str instead of string::data but remeber strlen returns the number of characters in the string excluding the zero terminator. If you don't want the terminator then string::size returns the number of characters in the string.

I modified my code to use char pointer vector, but this still doesn't work.. it gives another error now:

void SessionCreator( void *ch ) 
{
    vector<char *> users;
 
    // Split the string
    Split((char *)ch, ", ", users);
 
    ChatSession cs;
 
    // Initialize the ssesions array with each user
    for (int i = 0; i < (int)users.size(); i++)
    {
        cs = new ChatSession(users[i]);
        ssid.push_back(cs);
    }
 
    // Terminate myself
    _endthread();
}

Line: cs = new ChatSession(users[i]);

error C2679: binary '=' : no operator found which takes a right-hand operand of type 'ChatSession *' (or there is no acceptable conversion)

@Banfa
Removing the pointer sign gives me the same error as above,
but thanks for telling me about strlen() else i would leave it in numerous places like that and it'd keep me puzzled :D

@mcco
cs is an object (of type ChatSession), new ChatSession(users[i]) has type ChatSession *

Perhaps cs should be a pointer?
