怎么把一个CString 类型的变量转换成 int 类型的变量?

int n = atoi((LPCTSTR)s);
int kk = (int)atoi(ss.GetBuffer(lstrlen(ss)));
BTW:真受不了了,美女又怎么样。来这里是互相帮助的
CString s;int nResult=sscanf((const char *)s,"%d",&n);性别无法证实,是否美女也无法证实。上当也认了!
int n = atoi((LPSTR)(LPCTSTR)cs);
有男朋友吗?我是帅哥,交个朋友好吗?
CString cs;
int n = atoi((LPSTR)(LPCTSTR)cs);
int a = atoi(cs);
这样总可以了吧。不管是不是美女,我都要说。

PART ONE :- DECIMAL CONVERSIONSDecimal To Hexa :-
------------------Use _itoa( ) function and set radix to 16.char hexstring[10];
int number = 30;
itoa( number, hexstring, 16);In hexstring is 1e.
Hexa To Decimal :-
------------------
a)
You can use strtol function and you can specify base.
char * hexstring= "ABCDEF";
char * p;
int number = strtol(hexstring, &p,16);b)
bool HexToDecimal (char* HexNumber, int& Number)
{
char* pStopString;
Number = strtol (HexNumber, &pStopString, 16);
return (bool)(Number != LONG_MAX);
}
Decimal to Time :-
------------------char *DecToTime(float fTime, char *szTime)
{
int nHrs, nMin, nSec;
fTime *= 3600;
nHrs = (int)fTime / 3600;
nMin = (int)(fTime - nHrs * 3600) / 60;
nSec = (int)(fTime - nHrs * 3600 - nMin * 60);
wsprintf(szTime, "%02d.%02d.%02d Hrs.Min.Sec.", nHrs, nMin, nSec);
return szTime;
}PART TWO :- STRING CONVERSIONS
String to Hexa :-
-----------------sscanf(string, %04X, &your_word16);
// where string = your string and 04 = length of your string and X = hex
Hex to CString
---------------CString Str;
unsigned char Write_Buff[1];
Write_Buff[0] = 0x01;
Str.Format("0x0%x",Write_Buff[0]);
COleVariant to CString
----------------------CString strTemp;
COleVariant Var;
Var = "FirstName";
strTemp = Var.bstrVal;
AfxMessageBox(strTemp);
CString to Char Pointer
-----------------------
a)
CString MyString = "ABCDEF";
char * szMyString = (char *) (LPCTSTR) MyString;b)
char *pBuffer = new char[1024];
CString strBuf = "Test";
pBuffer = strBuf.GetBuffer(sizeof(pBuffer));
Char Pointer to CString
-----------------------char * mystring = "12345";
CString string = mystring;
Double to CString including the fractional part :-
--------------------------------------------------CString strValue,strInt, strDecimal;
int decimal,sign;
double dValue = 4.125;
strValue = _fcvt(dValue,6,&decimal,&sign); // Now decimal contains 1 because there is only one digit before the .
strInt = strValue.Left(decimal); // strInt contains 4
strDecimal = strValue.Mid(decimal); // strDecimal contains 125CString strFinalVal;
strFinalVal.Format("%s.%s",strInt,strDecimal); // strFinalVal contains 4.125
Double To CString :-
--------------------
CString strValue;
int decimal,sign;double dValue = 123456789101112;
strValue = _ecvt(dValue,15,&decimal,&sign); // Converting double to string
CString To Double :-
---------------------strValue = "121110987654321";
dValue = atof(strValue);
CString to LPCSTR :-
--------------------CString str1 = _T("My String");
int nLen = str1.GetLength();
LPCSTR lpszBuf = str1.GetBuffer(nLen);
// here do something with lpszBuf...........
str1.ReleaseBuffer();
CString to LPSTR :-
--------------------CString str = _T("My String");
int nLen = str.GetLength();
LPTSTR lpszBuf = str.GetBuffer(nLen);
// here do something with lpszBuf...........
str.ReleaseBuffer();
CString to WCHAR*
-----------------CString str = "A string here" ;
LPWSTR lpszW = new WCHAR[255];LPTSTR lpStr = str.GetBuffer( str.GetLength() );
int nLen = MultiByteToWideChar(CP_ACP, 0,lpStr, -1, NULL, NULL);
MultiByteToWideChar(CP_ACP, 0, lpStr, -1, lpszW, nLen);
AFunctionUsesWCHAR( lpszW );
delete[] lpszW;
LPTSTR to LPWSTR
----------------
int nLen = MultiByteToWideChar(CP_ACP, 0, lptStr, -1, NULL, NULL);
MultiByteToWideChar(CP_ACP, 0, lptStr, -1, lpwStr, nLen);
string to BSTR
--------------
string ss = "Girish";
BSTR _bstr_home = A2BSTR(ss.c_str());
CString to BSTR
---------------
CString str = "whatever" ;
BSTR resultsString = str.AllocSysString();
_bstr_t to CString
-------------------#include
#include
_bstr_t bsText("Hai Bayram");
CString strName;
W2A(bsText, strName.GetBuffer(256), 256);
strName.ReleaseBuffer();
AfxMessageBox(strName);char szFileName[256];
GetModuleFileName(NULL,szFileName,256);
AfxMessageBox(szFileName);
PART THREE :- CHARACTER ARRAYSChar array to integer
---------------------char MyArray[20];
int nValue;nValue = atoi(MyArray);
Char array to float
-------------------char MyArray[20];
float fValue;fValue = atof(MyArray);
Char Pointer to double
----------------------char *str = " -343.23 ";
double dVal;
dVal = atof( str );
Char Pointer to integer
-----------------------char *str = " -343.23 ";
int iVal;
iVal = atoi( str );
Char Pointer to long
--------------------char *str = "99999";
long lVal;
lVal = atol( str );
Char* to BSTR
-------------
char * p = "whatever";
_bstr_t bstr = p;
Float to WORD and Vice Versa
-----------------------------
float fVar;
WORD wVar;
fVar = 247.346;
wVar = (WORD)fVar; //Converting from float to WORD. The value in wVar would be 247
wVar = 247;
fVar = (float)fVar; //Converting from WORD to float. The value in fVar would be 247.00
小妹妹,你打不打Counter-Strike?有空Q我,14669878。
漂亮女人都要有钱男人养者,哪有要自己出来编程的呀
_ttol(CString szString)
大家就看看是不是
if 是
给我
else
垃圾扔了
else
说谎
int n = atoi((LPCTSTR)s);
int n = atoi(str.GetBuffer(str.GetLength()));
LPCTSTR lpSrc
);
#include <shlwapi.h>
shlwapi.lib
其它同上。
