读取文件提示“对一个未命名的文件的存取被拒绝”

Question

///写
CFile file;
if(!file(lppath,CFile::modeRead|CFile::modeWrite|CFile::modeCreate))
{
TRACE("create file error\n"）;
return ;
}
char lpbuf[32];
...
file.Write(lpbuf,strlen(lpbuf));
file.Close();//读
CFile file;
if(!file(lppath,CFile::modeRead|CFile::modeWrite)
{
TRACE("open file error\n"）;
return ;
}
char lpbuf[32];
...
file.Read(lpbuf,5);////出错
file.Close();

Answer 1

file.Open(lppath,CFile::modeRead|CFile::modeWrite);

Answer 2

file(lppath,CFile::modeRead|CFile::modeWrite|CFile::modeCreate)
file(lppath,CFile::modeRead|CFile::modeWrite)
不写open都可以？

Answer 3

应该用Open函数。或者直接CFile file(lppath,CFile::modeRead|CFile::modeWrite|CFile::modeCreate)

Answer 4

Open函数打开没有提示如何信息，表示已经打开了啊？

Answer 5

上面的代码写错了。if(!file.Open(lppath,CFile::modeRead|CFile::modeWrite|CFile::modeCreate))
{
TRACE("create file error\n"）;
return ;
}

Answer 6

if(!file.Open(lppath, CFile::modeRead | CFile::modeReadWrite))
{
TRACE("create file error\n"）;
return ;
}

Answer 7

CFile::modeRead = 0
CFile::modeReadWrite = 1
则
CFile::modeRead | CFile::modeReadWrite = 1 
所以CFile::modeRead | CFile::modeReadWrite == CFile::modeReadWrite
当然不能读了！
将CFile::modeRead | CFile::modeReadWrite改为CFile::modeReadWrite
