暴简单的console程序怎么就不行呢？——怎么列出某一目录下的所有文件名？

[Ashura]

int _tmain(int argc, TCHAR* argv[], TCHAR* envp[])
{
int nRetCode = 0;
CString strDir;
CFileFind Finder;
BOOL bWorking;
CString strFixedFile = "*.*";
CString strFileName;

// initialize MFC and print and error on failure
if (!AfxWinInit(::GetModuleHandle(NULL), NULL, ::GetCommandLine(), 0))
{
// TODO: change error code to suit your needs
cerr << _T("Fatal Error: MFC initialization failed") << endl;
nRetCode = 1;
}
else
{
printf((LPCSTR)"Please enter the directory:\n");
scanf("%s", strDir);
strDir += _T('\\');
strDir += strFixedFile;
printf((LPCSTR)strDir);
bWorking = Finder.FindFile(strDir);
while( bWorking )
{
bWorking = Finder.FindNextFile();
if ( Finder.IsDots() )
continue;
strFileName = Finder.GetFileName();
printf((LPCSTR)strFileName);
}
}

return nRetCode;
}

一个如此简单的打印某一目录下所有文件名的程序怎么就没有正确结果？
不管怎么给path，得到的总是d:盘下的一级子目录名，faint！

ok！

[kingfish]

strDir += _T('\\*.*');

[luckyegg]

if ( Finder.IsDots() )有问题呀.把strFileName = Finder.GetFileName();放到if前面，应判断strFileName是不是目录,是则continue,不是则打印

[kingfish]

不好意思,上面写错了,
strDir += _T('\\'); // 这句有问题

[kingfish]

char strbuf[256];
scanf("%s", strbuf);
strDir = strbuf;

kao，麻烦哪位好心的兄弟帮偶run一把，感激不尽！

int _tmain(int argc, TCHAR* argv[], TCHAR* envp[])
{

int nRetCode = 0;
CString strDir;
CFileFind Finder;
BOOL bWorking;
CString strFixedFile = "*.*";
CString strFileName;


// initialize MFC and print and error on failure
if (!AfxWinInit(::GetModuleHandle(NULL), NULL, ::GetCommandLine(), 0))
{
// TODO: change error code to suit your needs
cerr << _T("Fatal Error: MFC initialization failed") << endl;

// TODO: code your application's behavior here.
printf((LPCSTR)"Please enter the directory:\n");
char str[MAX_PATH];
scanf("%s", str);
strDir.Format("%s",str);
strDir += "\\";
strDir += strFixedFile;
printf("\n");
printf((LPCSTR)strDir);
printf("\n");
bWorking = Finder.FindFile(strDir);
while( bWorking )
{
bWorking = Finder.FindNextFile();
if ( Finder.IsDots() )
continue;
strFileName = Finder.GetFileName();
printf("\n%s",(LPCSTR)strFileName);
}

}

return nRetCode;
}
//尽量不要用操作c的函数操作CString

巨简单，改动如下：

int _tmain(int argc, TCHAR* argv[], TCHAR* envp[])
{
int nRetCode = 0;
//CString strDir;
char strDir[200]; //这里改了。


CFileFind Finder;
BOOL bWorking;
CString strFixedFile = "*.*";
CString strFileName;

// initialize MFC and print and error on failure
if (!AfxWinInit(::GetModuleHandle(NULL), NULL, ::GetCommandLine(), 0))
{
// TODO: change error code to suit your needs
cerr << _T("Fatal Error: MFC initialization failed") << endl;
nRetCode = 1;
}
else
{
printf((LPCSTR)"Please enter the directory:\n");
scanf("%s", strDir);
//printf((LPCSTR)strDir);
//strDir += _T("\\");
//strDir += strFixedFile;
sprintf(strDir,"%s\\*.*",strDir); //这里更简单了。
printf((LPCSTR)strDir);

bWorking = Finder.FindFile(strDir);
while( bWorking )
{
bWorking = Finder.FindNextFile();
if ( Finder.IsDots() )
continue;
strFileName = Finder.GetFileName();
strFileName+="\n";
printf((LPCSTR)strFileName);
}
}

return nRetCode;
}
没问题了，原因：你用CString,'\'就不能表示正确的目录了。那FindFile就认为是NULL,你的程序在d:下，所以如此。FindFile第一个参数应该为"c:\\windows\*.*"之类的字符串。
