Answer 1

#include <afx.h>
void main()
{
//CFile::modeRead;      //In
//CFile::modeWrite;     //Out
//CFile::modeReadWrite; //InOut
//CFile::modeCreate     //创建文件(存在则清空)
//CFile::modeNoTruncate //不存在则创建，存在则继续写入
CFile cfFile(_T("a.txt"),CFile::modeReadWrite|CFile::modeCreate);
unsigned long uiValue=10;
cfFile.Write(&uiValue,sizeof(long));
cfFile.Flush();
cfFile.Close();
}
