我想编辑一个按钮让这个按钮能保存编辑框中的文字，现在知道能用CFile类，但是具体的代码看不明白
   HANDLE hFile = CreateFile(_T("D:\\MyFile.DAT"),
         GENERIC_WRITE, FILE_SHARE_READ,
         NULL, CREATE_ALWAYS, FILE_ATTRIBUTE_NORMAL, NULL);

   if (hFile == INVALID_HANDLE_VALUE)
      AfxMessageBox(_T("Couldn't create the file!"));
   else
   {
      // Attach a CFile object to the handle we have.
       CFile myFile(hFile);

      static const char sz[] = "Hockey is best!";

      // write string, without null-terminator
      myFile.Write(sz, lstrlen(sz));

      // We can call Close() explicitly, but the destructor would have
      // also closed the file for us. Note that there's no need to
      // call the CloseHandle() on the handle returned by the API because
      // MFC will close it for us.
      myFile.Close();
   }
请高手们指教

   HANDLE hFile = CreateFile(_T("D:\\MyFile.DAT"),
         GENERIC_WRITE, FILE_SHARE_READ,
         NULL, CREATE_ALWAYS, FILE_ATTRIBUTE_NORMAL, NULL);

   if (hFile == INVALID_HANDLE_VALUE)
      AfxMessageBox(_T("Couldn't create the file!"));
   else
   {
      // Attach a CFile object to the handle we have.
       CFile myFile(hFile);

      static const char sz[] = "Hockey is best!";

      // write string, without null-terminator
      myFile.Write(sz, lstrlen(sz));

      // We can call Close() explicitly, but the destructor would have
      // also closed the file for us. Note that there's no need to
      // call the CloseHandle() on the handle returned by the API because
      // MFC will close it for us.
      myFile.Close();
   }

逐个百度出红色标注的程序功能，就可以明白这段代码在干什么了。我就是这样学习的。

这个不是msdn上的么。先创建一个文件，然后用得到的句柄来给一个CFile对象赋值，在往里面写东西，最后关闭句柄。
今天我也用了这个，可是在evc下面有问题，那个CreateFile得到的句柄不能直接传递给CFile对象，不知道在Vc6下面行不行

那个CreateFile得到的句柄不能直接传递给CFile对象
--- 干嘛要用CFile？直接用 WriteFile，完毕后用 CloseHandle
