Volume Serial Number?Hi there, Is there an easy was to detect the Volume Serial Number (eg.3155-1BD1) of a diskette/CD/Hard Drive or will I need a special third party component? Thanks for the Help, Steve. |

Re:Volume Serial Number?QuoteStefan Paege wrote: system and volume whose root directory is specified. BOOL GetVolumeInformation( LPCTSTR lpRootPathName, // address of root directory of the file system LPTSTR lpVolumeNameBuffer, // address of name of the volume DWORD nVolumeNameSize, // length of lpVolumeNameBuffer LPDWORD lpVolumeSerialNumber, // address of volume serial number LPDWORD lpMaximumComponentLength, // address of system's maximum filename length LPDWORD lpFileSystemFlags, // address of file system flags LPTSTR lpFileSystemNameBuffer, // address of name of file system DWORD nFileSystemNameSize // length of lpFileSystemNameBuffer ); Parameters lpRootPathName Points to a string that contains the root directory of the volume to be described. If this parameter is NULL, the root of the current directory is used. lpVolumeNameBuffer Points to a buffer that receives the name of the specified volume. nVolumeNameSize Specifies the length, in characters, of the volume name buffer. This parameter is ignored if the volume name buffer is not supplied. lpVolumeSerialNumber Points to a variable that receives the volume serial number. This parameter can be NULL if the serial number is not required. lpMaximumComponentLength Points to a doubleword value that receives the maximum length, in characters, of a filename component supported by the specified file system. A filename component is that portion of a filename between backslashes. The value stored in variable pointed to by *lpMaximumComponentLength is used to indicate that long names are supported by the specified file system. For example, for a FAT file system supporting long names, the function stores the value 255, rather than the previous 8.3 indicator. Long names can also be supported on systems that use the NTFS and HPFS file systems. lpFileSystemFlags Points to a doubleword that receives flags associated with the specified file system. This parameter can be any combination of the following flags, with one exception: FS_FILE_COMPRESSION and FS_VOL_IS_COMPRESSED are mutually exclusive. Value Meaning FS_CASE_IS_PRESERVED If this flag is set, the file system preserves the case of filenames when it places a name on disk. FS_CASE_SENSITIVE If this flag is set, the file system supports case-sensitive filenames. FS_UNICODE_STORED_ON_DISK If this flag is set, the file system supports Unicode in filenames as they appear on disk. FS_PERSISTENT_ACLS If this flag is set, the file system preserves and enforces ACLs. For example, NTFS preserves and enforces ACLs, HPFS and FAT do not. FS_FILE_COMPRESSION The file system supports file-based compression. FS_VOL_IS_COMPRESSED The specified volume is a compressed volume; for example, a DoubleSpace volume. lpFileSystemNameBuffer Points to a buffer that receives the name of the file system (such as FAT, HPFS, or NTFS). nFileSystemNameSize Specifies the length, in characters, of the file system name buffer. This parameter is ignored if the file system name buffer is not supplied. Return Value If all the requested information is retrieved, the return value is TRUE; otherwise, it is FALSE. To get extended error information, call GetLastError. Remarks The FS_VOL_IS_COMPRESSED flag is the only indicator of volume-based compression. The file system name is not altered to indicate compression. This flag comes back set on a DoubleSpace volume, for example. With volume-based compression, an entire volume is either compressed or not compressed. The FS_FILE_COMPRESSION flag indicates whether a file system supports file-based compression. With file-based compression, individual files can be compressed or not compressed. The FS_FILE_COMPRESSION and FS_VOL_IS_COMPRESSED flags are mutually exclusive; both bits cannot come back set. The maximum component length value, stored in the DWORD variable pointed to by lpMaximumComponentLength, is the only indicator that a volume supports longer-than-normal FAT (or other file system) file names. The file system name is not altered to indicate support for long file names. The GetCompressedFileSize function obtains the compressed size of a file. The GetFileAttributes function can determine whether an individual file is compressed. Pdf hedge fund trading strategies workshop organization.
