Hi

Any good way to convert number (e.g. UINT, int etc) to CString & vice-versa..... Right now, my method is
===================
int i = 30;
CString cStr;
char str[10];

sprintf(str,"%d",i);
cStr = str;
============

Which I find is not good becos I need to use a char array....

CString -> int:
   cStr.Format("%d",i);

int -> CString:
   int i = atoi(cStr);

From number to string:
 - you can use all facilitys of from sprintf when you are using
CString.Format() method of CString class.
 -  call this member function to write formatted data to a CString in the same way that sprintf formats data into a C-style character array.
From string to number:
 -these following  routines convert data from one form to another. Generally these routines execute faster than conversions you might write. Each routine that begins with a to prefix is implemented as a function and as a macro.

Routine                                        Use


atof                                               Convert string to float
atoi, _atoi64                                 Convert string to int
atol                                               Convert string to long
strtod, wcstod                              Convert string to double
strtol, wcstol                                 Convert string to long integer
strtoul, wcstoul                 Convert string to unsigned longinteger
