求问vC6.0的MFC中如何将Cstring型转换为DouBlE型,...

如果你的工程是Unicode版本的话 转成int: ;int a = _wtoi(str.GetBuffer()); 转成double: double b = _wtof(str.GetBuffer());

CString str= "0xf4"; int L = str.GetLength(); int sum(0),temp(0); for (int i = 2; i != L;i++) { sscanf(str.Mid(i,1),"%x",&temp); sum += temp*(pow(16,L-1-i)); } 这段代码是将CString类型的16进制,转化为了整数!

下面这个例子供参考: CString strValue("1.234"); double dblValue; dblValue = atof((LPCTSTR)strValue); 下面这个例子: char *s; double x; s = " -2309.12E-15"; x = atof( s ); printf( "atof test: ASCII string: %s\tfloat: %e\n", s, x...

方法一: 直接转换成double型。 CString csTemp; double dTemp; /...................../ csTemp.Format("%d", dTemp); 方法二: 先利用(atof()与trtod(nptr,(char**)NULL))转换成int,再转double型。 #include #include using namespace std; ...

给你三种方法 int iVar = 4156; CString csStr; csStr.Format("%d", iVar); SetDlgItemText(IDC_EDIT1, csStr); /* int iVar = 7489; char szBuf[100]; _itoa(iVar, szBuf, 10); CString csStr(szBuf); SetDlgItemText(IDC_EDIT1, csStr); */ /*...

unsigned char *p_IP; CString strIP; DWORD dwIP; //从控件中获取IP m_ipAddr.GetAddress(dwIP); p_IP = (unsigned char*)&dwIP; strIP.Format("%u.%u.%u.%u",*(p_IP+3), *(p_IP+2), *(p_IP+1), *p_IP);

strcpy(person1.name, (LPCTSTR)m_1); //sprintf(person1.name, "%s", (LPCTSTR)m_1) cstring重载了 运算符----------> CString::operator LPCTSTR operator LPCTSTR ( ) const; Return Value A character pointer to the string’s data.

#include "stdio.h" void main() { int a[9]={1,3,5,7,9,10,12,14}; int b,i,j; scanf("%d",&b); for(i=0;i=b){ /*找到插入位置*/ for(j=8;j>i;j--) /*后面元素均后移一位*/ a[j] = a[j-1]; a[i] = b; /*插入*/ break; } } if(i==8) /*若该数大...

方法一MFC http://support.microsoft.com/kb/120961/zh-cn 方法二STL 使用STL的string和sort排序,然后将排好的每个string转为CString

CString m_FileName; char* pc = (LPSTR)(LPCTSTR)m_FileName;
