WINCE 文本读写操作总结

#include "stdafx.h"
#include <windows.h>
#include <commctrl.h>

 

//1.C语言函数fopen(),式例代码：

#include <stdio.h>  
#include <tchar.h>   

int _tmain(int argc, _TCHAR* argv[])   
{   
 // 创建或打开二进制文件,并以追加方式打开   
 FILE *pFile=_tfopen(_T("\\Program Files\\FileLog1.txt"), _T("wab+"));  
 if(pFile)   
 {   
  fwprintf(pFile, _T("%s\n"), _T("test1"));   
  fwprintf(pFile, _T("%s\n"), _T("test2"));   
  fwprintf(pFile, _T("%s\n"), _T("test3"));   
  fclose(pFile);   
 }   

 // 读文件   
 pFile=_tfopen(_T("\\Program Files\\FileLog1.txt"), _T("rb"));  
 TCHAR str[20];   
 if(pFile)   
 {   
  while(_ftscanf(pFile,_T("%s\n"),str)!=EOF)   
  {   
   _tprintf(_T("%s\n"),str);   
  }   
  fclose(pFile);   
 }   
 return 0;   
}  

 

//2.C++ fstream,式例代码：
  

#include <tchar.h>   
#include <fstream>   
#include <string>   
#include <iostream>   
using namespace std;   

int _tmain(int argc, _TCHAR* argv[])   
{   
 fstream file;   
 // 以追加方式打开文件，只写操作   
 file.open("\\Program Files\\FileLog1.txt", ios_base::out | ios_base::app);  
 if(file.is_open())   
 {   
  file << "test1" << endl;   
  file << "test2" << endl;   
  file << "test3" << endl;   
  file.flush();   
  file.close();   
 }      

 // 以只读方式打开文件   
 file.open("\\Program Files\\FileLog1.txt", ios_base::in);  
 if(!file.is_open())   
 {   
  cout << "Open file failed"<<endl;   
  exit (1);   
 }   
 string str;   
 while (!file.eof())   
 {    
  // 获取一行数据   
  getline(file,str);   
  cout << str.c_str() << endl;   
 }   
 file.close();   
 return 0;   
} 

 

 

//3.mfc CFile、CStdioFile类

//CFile 写文件操作示例，支持ANSI、UNICODE中文输出。

#include <tchar.h>   
#include <afx.h>   

int _tmain(int argc, _TCHAR* argv[])   
{   
 CFile cFile;   
 if(cFile.Open(_T("\\Program Files\\FileLog1.txt"),CFile::shareExclusive|CFile::modeCreate|CFile::modeWrite))  
 {   
#ifdef  _UNICODE   
  ULONGLONG dwFileLen = cFile.GetLength();      
  if (0 == dwFileLen) // 文件为空时写入UNICODE字节序标记      
  {      
   const unsigned char LeadBytes[]  = {0xff, 0xfe};      
   cFile.Write(LeadBytes, sizeof(LeadBytes));      
  }   
#endif   
  TCHAR *str=_T("中文字符串");   
  cFile.Write(str,_tcslen(str)*sizeof(TCHAR));   
  cFile.Close();   
 }   
 else  
 {   
  printf("Create file failed\n");   
 }   
 return 0;   
}  

 

//CStdioFile读写文件

#include <tchar.h>   
#include <afx.h>   

int _tmain(int argc, _TCHAR* argv[])   
{   
 CStdioFile cFile;   
 // 写文件   
 if(!cFile.Open(_T("\\Program Files\\FileLog1.txt"),CFile::modeCreate | CFile::modeWrite | CFile::typeBinary))  
 {   
  printf("Create file failed..\n");   
  return false;   
 }   

 cFile.WriteString(L"test1");   
 cFile.WriteString(L"test2");   
 cFile.WriteString(L"test3");   
 cFile.Close();   

 // 读文件   
 if(!cFile.Open(_T("\\Program Files\\FileLog1.txt"),CFile::modeRead | CFile::typeBinary))  
 {   
  printf("Open file failed..\n");   
  return false;   
 }   
 CString str;   
 while(cFile.ReadString(str))   
 {   
  // 输出   
  _tprintf(_T("%s\n"),str);   
 }   
 cFile.Close();   
 return 0;   
}
