1 conversion between the cstring,int,string,char*
String Turn CString
Cstring.format ("%s", String.c_str ());
Char turn CString
Cstring.format ("%s", char*);
Char Turn string
string S (char *);
String char *
Char *p = STRING.C_STR ();
CString turn std::string
CString str = dlg. GetPathName (); SetLocale (Lc_all, "CHS");
Char *p = new char[256];
Wcstombs (P, str, 256);
M_filename = p;
1,string-> CString cstring.format ("%s", String.c_str ()); it's better than data () with C_STR (). 2,char-> String
string S (char *);
Your can only initialize, in the place that does not initialize is best still use assign (). 3,cstring-> String String s (Cstring.getbuffer ()); GetBuffer () must be releasebuffer (), otherwise there is no space to free the buffer.
In the C + + standard library of functions.
There are three functions that can convert the contents of a string into character arrays and c-string
1.data (), returns a string array 2,c_str () without "", returns a string array with "" 3,copy ()
CString Cross int
Converts a character to an integer, and you can use Atoi, _atoi64, or ATOL.
To convert a number to a CString variable, you can use the CString format function. Such as
CString s;
int i = 64;
S.format ("%d", i) the Format function is very powerful and worth studying.
void Cstrdlg::onbutton1 ()
{
Todo:add your control notification handler code here
CString
Ss= "1212.12";
int Temp=atoi (ss);
CString AA;
Aa. Format ("%d", temp);
AfxMessageBox ("var is" + AA);
}
Sart. Format ("%s", buf);
CString Mutual Turn char*
char * to CString
CString strtest;
char * CHARPOINT;
Charpoint= "Give string a value";
Strtest=charpoint;
CString to char *
Charpoint=strtest. GetBuffer (strtest. GetLength ());
There is no String,char *==char in standard C []==string
You can use the Cstring.format ("%s", char *) method to turn char * to CString. To convert the CString to char *, use the operator (LPCSTR) to CString it.
CString conversion char[100]
Char a[100];
CString Str ("aaaaaa");
strncpy (A, (LPCTSTR) str,sizeof (a));
2 conversion of CString type to int
Convert CString type to int
Converts a character to an integer, and you can use Atoi, _atoi64, or ATOL.
CString AAA = "16";
int int_chage = Atoi ((LPCSTR) AAA);
To convert a number to a CString variable, you can use the CString format function. Such as
CString s;
int i = 64;
S.format ("%d", i) the Format function is very powerful and worth studying.
If you are using a char array, you can also use the sprintf function.
CString ss= "1212.12";
int Temp=atoi (ss);
CString AA;
Aa. Format ("%d", temp);
Digital-> strings are Cstring::format, FORMATV, sprintf and AFX Itoa
3 char* in the loading int
#include <stdlib.h>
int atoi (const char *nptr);
Long Atol (const char *nptr);
Long Long Atoll (const char *nptr);
Long Long Atoq (const char *nptr);
4 Conversion between the cstring,int,string,char*
String AA ("AAA");
Char *c=aa.c_str ();
Cannot convert from ' const char * ' to ' char * '
const char *C=AA.C_STR ();
The conversion between 5 cstring,int,string,char* string.c_str () can only be converted to const char *,
To convert to char * This writes:
String Mngname;
Char t[200]; memset (t,0,200); strcpy (T,mngname.c_str ());
