Read and Write Text Files in WinCE

Environment: Windows CE 3.0

Introduction

The CStudioFile class is intended for WinCE MFC applications because MFC for WinCE did not implement the CStdioFile text file functions. You should use the CStdioFile in Win32 programs.

Example 1, Illustrating How to Read a Text File Using CString

  CStudioFile f;
  CString s;
  CString output;
  f.Open(L"index.html",
         CFile::modeRead | CFile::shareExclusive |
         CFile::typeText);
  while(f.ReadString(s,false))
  {
    output += s;
  }
  f.Close();

Example 2, Illustrating How to Read an ASCII-Formatted File

  CStudioFile f;
  char buf[255];
  CString output;
  f.Open(L"index.html",
         CFile::modeRead | CFile::shareExclusive |
         CFile::typeText);
  while(f.ReadString(buf, sizeof(buf))
  {
    output += buf;
  }
  f.Close();

Example 3, Illustrating How to Read an UNICODE-Formatted File

  CStudioFile f;
  wchar_t buf[255];
  CString output;
  f.Open(L"index.html", 
         CFile::modeRead | CFile::shareExclusive |
         CFile::typeText);
  while(f.ReadString(buf, sizeof(buf))
  {
    output += buf;
  }
  f.Close();
