Stringw problem

[zenaku]

Ok, I found a more elegant solution. Sorry, I'm kind of an Irrlicht n00b myself.

Code: Select all

core::stringw  GetCommand = EditBox->getText();

// core::string overloads operator '==', so this works correctly
if(GetCommand == L"hide node")
{
    q3node->setVisible(false);
} 

or even shorter

Code: Select all

if(core::stringw(EditBox->getText()) == L"hide node")
{
    q3node->setVisible(false);
}

I use exacly this solution what you have posted above (I posted it myself at the begining and it was working, just there was a problem with 'one missing space' ..., so it should be if(GetCommand == L"hide node ") <- space after hide node).

Thanx again very very much

wow this is great, you have also taught me how to grab the text in an edit box, however, would the code to grab the text go in a function at the top? for when enter key is pressed, as i would like it so you would press enter, yuo can edit the editbox, and then press enter again to submit ur text (for a chat system),, if not i guess i will just leave it as click on he box type and press enter.

hello, i have got some trouble converting a stringw to a char.

this is the code atm

Code: Select all

stringw message = chat->getText().c_str(); 
							stringw name = person->getText().c_str();
							SendData(name, message);
							stringw data = SendData(name, message);

it connects to a network code i wrote using sockets etc. and it uses char. However the main problem i get is with this...

Code: Select all

stringw message = chat->getText().c_str();

it keeps on displaying this error

Code: Select all

52 C:\dark chasis\Engine\network_chat\chat.cpp `c_str' has not been declared

what is wrong ... these are the current headers i have included

Code: Select all

#include <irrlicht.h>
#include <wchar.h>
#include <windows.h>
#include <winsock.h>
#include <stdio.h>
#include <string.h>
#include <irrString.h>
#include "senddata.h"

I think the problem is that getText() already returns a wchar_t* so no need to convert it. Just remove c_str() and you're fine. Even if getText() would return stringw the code would be better without c_str() in order to avoid too many conversions.
Does SendData take stringw as parameters? Otherwise you should convert in a different way.

[kamadian]

if i take the .c_str() out it sends another awkard message.

Code: Select all

55 C:\dark chasis\Engine\network_chat\chat.cpp cannot convert `irr::core::stringw' to `char*' for argument `1' to `char* SendData(char*, char*)' 

what i am basically trying to do is convert the stringw to a char string.

This is the SendData.h
not sure if it is right :S

Code: Select all

#ifndef _SENDDATA_H 
#define _SENDDATA_H 
 
char *SendData(char *, char *); 
 
#endif

thanks for the reply

Ok, that's good because now it reaches the SendData command. Now change all stringw to stringc and you should be done.

that didnt work so instead my friend and i made a unicode to ascii and ascii to unicode converter.

here they are

U2A

Code: Select all

void u2a(char *st1, char *st2)
{
   int i=0;
   while( st1 [ 2*i ] )
   {
      st2[ i ] = st1[ 2*i ];
      i++;
   }
   st2[ i ] = 0;
}

A2U

Code: Select all

void a2u( char *st1, char *st2)
{
   int i=0;
   while( st1[ i ] )
   {
      st2[ 2*i ] = st1[ i ];
      st2[ 2*i + 1 ] = 0;
      i++;
   }
   st2[ 2*i ] =0;
   st2[ 2*i+1 ] = 0;
}

and here is ym code all working

Code: Select all

char *message = (char *)(chat->getText());
char *name = (char *)(person->getText());
u2a(name, name_ascii);
u2a(message, message_ascii);
SendData(name_ascii, message_ascii);
FILE *out=fopen("log.txt","wb");
fwrite(name, 10,1,out);
fclose(out);
char *data, data_unicode[4096];;
data = SendData(name_ascii, message_ascii);
a2u(data, data_unicode);
chatwindow->addItem((wchar_t *)data_unicode);
chat->setText(L"");

however one problem i do have, it returns a load fo squares etc. before and after the message >.<

also the txt file is mostly for error handelling.

probably going way of topic now, but heck, i have a wierd problem
