Hi,
If you are using MFC , try this:
char *ID;
CString szString;
int abc = 10;
szString.Format("c%d" , abc);
ID = new char[szString.GetLength() + 1];
strcpy(ID , (LPCTSTR)szString);
If you are not using MFC , try this:
char *ID , Buffer[20] , temp = 'c';
int abc = 10;
_itoa( abc , Buffer , 10 );
ID = new char[strlen(Buffer) + 1];
ID[0] = 'c';
strcat(ID , Buffer);
With best regards,
Eli

itoa( abc , Buffer , 10 ); <== wat does this do?
to use this need to include any special things?
|
|
|
|
|
itoa(MSDN) -->Convert an integer to a string
int abc=10;
TCHAR Buffer[50];
itoa( abc , Buffer , 10 );->then Buffer==10

i tryed it but it says itoa is an undeclare variable
currently i using these include:
<br />
#include"iostream.h"<br />
#include"string.h"<br />
#include"iomanip.h"<br />

please test this code,it work
<br />
#include "stdafx.h"<br />
#include <iostream><br />
#include <tchar.h><br />
using namespace std;<br />
<br />
int _tmain(int argc, _TCHAR* argv[])<br />
{<br />
TCHAR Buffer[50];<br />
itoa(10,Buffer,10);<br />
cout<<"Value is="<<Buffer<<"\n";<br />
return 0;<br />
}<br />
can you show your code how to use itoa

this is my code
by the way #include "stdafx.h" dosnt seems to work i am using visual c++
also the other 2 include in your previosu example cant be seen >.<

i hope i am not troubleing u >.<
now the output is 10c i am trying to get c10 >.<
i already tried this:
ID="c";
strcat(ID ,Buffer);
got error...
|
|

|

well ok i mistake i think your problem is itoa so its easy use
<br />
<br />
#include "stdafx.h"<br />
#include windows.h<br />
#include iostream<br />
#include tchar.h<br />
using namespace std;<br />
<br />
<br />
int _tmain(int argc, _TCHAR* argv[])<br />
{<br />
char *ID;<br />
char temp = 'c';<br />
int abc = 1240;<br />
ID = new char[sizeof(ID)];<br />
<br />
wsprintf(ID,"%c%d",temp,abc);<br />
<br />
cout<<"Value="<<ID<<"\n";<br />
return 0;<br />
}<br />
<br />
<br />

i dont quite understand
my objective is actually to store the lettle "C" and an int into a string so the coutcome will become like this C10 or C203
curretly the include i am using are
#include"iostream.h"
#include"string.h"
#include"iomanip.h"
i not allowed to use namespace std haha >.<
so can anyone try help me ?

Instead of strcat() in my first answer , use the memcpy().
I tested this code and it's working:
char *ID , Buffer[20];
int abc = 10;
int nLen = 0;
_itoa( abc , Buffer , 10 );
nLen = strlen(Buffer);
ID = new char[nLen + 2];
ID[0] = 'c';
memcpy(ID + 1 , Buffer , strlen(Buffer));
ID[nLen + 1] = '\0';

i tryed it with include"iostream" it works but it dosnt work in include"iostream.h"
do i have to include nay additional stuff??
by the way i say thx to all those who have helped me in advance =)
really help a lot

I think your problem is solve.
Can you explain what do you need exactly,please?

yes my problme is solve but i cant use this function -->_itoa( abc , Buffer , 10 );
the itoa part dosnt work unless i use include"iostream" but i am using include"iostream.h"
so i am just asking there is anything else to include so that i may use include"iostream.h"
together with the itoa function

Yes, the prototype of the _itoa function is present in the stdlib.h header file
Knock out 't' from can't,
You can if you think you can
|

|
|
|
I rated you 1 -- it would be quicker for you to check MSDN library than to ask on CodeProject what itoa does.

=P
any way thx for all the help u guys gav me

want to check if a folder exists in a computer or not. for example if the path is
"c:\DK\Index " i want to check if the folders DK and Index already exists in c
drive. if it doesn't exist,then these folders should be created. if the folders already exists nothing needs to be done. i want to check this when the dialog box is initialised. can anyone give the code to do this.
Thank You

Hi ,
Try this :
CFileFind finder;
CString szPath , szCMD;
szPath = "c:\DK\Index";
if(!finder.FindFile(szPath))
{
szCMD = "mkdir ";
szCMD += szPath;
system((LPCTSTR)szCMD);
}
With best regards,
Eli

if(hFile==INVALID_HANDLE_VALUE) <br />
MessageBox("Not Found");<br />
else<br />
{<br />
MessageBox("ok");<br />
FindClose(hFile);<br />
