Converting of int to string and displaying

Question

After converting a string variable into int using _ttoi function , I need to convert it to String to display the value. This is the code :

My function:  

int i;
char buffer[20];
CString str;

i= _ttoi(myVal->GetText());  //convert string to int 
itoa (i,buffer, 10); //convert int back to string 

str.AppendFormat(_T("Value is : %s\n"), buffer);

But this does not display anything at all!!! Any ideas?

If this a trick question? You're mixing chars and wide chars. On one hand you use _ttoi and _T() and then char and itoa. And you probably build with UNICODE char set.

Make it like this and it will work.

int i;
TCHAR buffer[20];
CString str;

i= _ttoi(myVal->GetText());  //convert string to int
_itot(i, buffer, 10); //convert int back to string

str.AppendFormat(_T("Value is : %s\n"), buffer);

But why do you use itoa at all? Simply use CString::AppendFormat() or CString::Format() as already pointed out.

You don't need to use atoi at all. CString::AppendFormat or CString::Format does exactly what you want to do:

int i = 4711;
CString str;
str.Format (_T("My variable has value: %d\n"), i);

CString's formatting capacity is one of the best and very flexible.

Well thanks,
Had done major blunder by adding _ttoi instead of _ttof and yeah finally managed to get things in place.
