1. 使用_access函數(shù)，函數(shù)原型為 int _access( const char *path, int mode );
2. 使用CreateFile函數(shù)，函數(shù)原型為： HANDLE CreateFile( LPCTSTR lpFileName, // pointer to name of the file DWORD dwDesiredAccess, // access (read-write) mode DWORD dwShareMode, // share mode LPSECURITY_ATTRIBUTES lpSecurityAttributes, // pointer to security attributes DWORD dwCreationDisposition, // how to create DWORD dwFlagsAndAttributes, // file attributes HANDLE hTemplateFile // handle to file with attributes to // copy );
3. 使用FindFirstFile函數(shù)，函數(shù)原型為： HANDLE FindFirstFile( LPCTSTR lpFileName, // pointer to name of file to search for LPWIN32_FIND_DATA lpFindFileData // pointer to returned information );
//例子：
BOOL CPubFunc::DirectoryExist(CString Path)
{
WIN32_FIND_DATA fd;
BOOL ret = FALSE;
HANDLE hFind = FindFirstFile(Path, &fd);
if ((hFind != INVALID_HANDLE_VALUE) && (fd.dwFileAttributes & FILE_ATTRIBUTE_DIRECTORY))
{ //目錄存在
ret = TRUE;
}
FindClose(hFind);
return ret;
}
4. 使用GetFileAttributes函數(shù)，函數(shù)原型如下： DWORD GetFileAttributes( LPCTSTR lpFileName // pointer to the name of a file or directory );
5. 使用Shell Lightweight Utility APIs函數(shù) PathFileExists（）專門判斷文件和目錄時否存在的函數(shù)文件名可讀性比較強還可以判斷目錄是否存在 Header: Declared in Shlwapi.h Import Library: Shlwapi.lib 以上的各種方法供參考，函數(shù)具體用法需參見MSDN。
//這是MSDN中的例子：
#include <windows.h>
#include <iostream.h>
#include "Shlwapi.h"
void main( void )
{
// Valid file path name (file is there).
char buffer_1[] = "C:\\TEST\\file.txt";
char *lpStr1;
lpStr1 = buffer_1;
// Invalid file path name (file is not there).
char buffer_2[] = "C:\\TEST\\file.doc";
char *lpStr2;
lpStr2 = buffer_2;
// Return value from "PathFileExists".
int retval;
// Search for the presence of a file with a true result.
retval = PathFileExists(lpStr1);
if(retval == 1)
{
cout << "Search for the file path of : " << lpStr1 << endl;
cout << "The file requested \"" << lpStr1 << "\" is a valid file" << endl;
cout << "The return from function is : " << retval << endl;
}
else{
cout << "\nThe file requested " << lpStr1 << " is not a valid file" << endl;
cout << "The return from function is : " << retval << endl;
}
// Search for the presence of a file with a false result.
retval = PathFileExists(lpStr2);
if(retval == 1)
{
cout << "\nThe file requested " << lpStr2 << "is a valid file" << endl;
cout << "Search for the file path of : " << lpStr2 << endl;
cout << "The return from function is : " << retval << endl;
}
else{
cout << "\nThe file requested \"" << lpStr2 << "\" is not a valid file" << endl;
cout << "The return from function is : " << retval << endl;
}
}
6.使用CFileFind 類....這是一個InternetServices類，在此可以借用一下。也可以用于遍歷文件夾（s可指定深度）
BOOL CPubFunc::FileExist(CString FileName)
{
CFileFind fFind;
return fFind.FindFile(FileName);
}
//創(chuàng)建目錄
#include <winbase.h>
BOOL CreateDirectory(
LPCTSTR lpPathName, // pointer to directory path string
LPSECURITY_ATTRIBUTES lpSecurityAttributes // pointer to security descriptor
);
