检测文件存在的四种方法。test if a File exist or not?

1. WIN32_FIND_DATA m_data; HANDLE hFile; hFile=FindFirstFile(filename,&m_data) if(hFile==INVALID_HANDLE_VALUE) //file not found Make sure you close the handle if the file is found. FindClose(hFile); 2. You can use SHGetFileInfo() The prototype of the function is as follows:

DWORD_PTR SHGetFileInfo( LPCTSTR pszPath,DWORD dwFileAttributes,SHFILEINFO *psfi,UINT cbFileInfo,UINT uFlags);

3. PathFileExists 4. 加一个标准c库函数

Example

/* ACCESS.C: This example uses _access to check the * file named "ACCESS.C" to see if it exists and if * writing is allowed. */#include #include #include void main( void ){ /* Check for existence */ if( (_access( "ACCESS.C", 0 )) != -1 ) { printf( "File ACCESS.C exists\n" ); /* Check for write permission */ if( (_access( "ACCESS.C", 2 )) != -1 ) printf( "File ACCESS.C has write permission\n" ); }}
