1. The following example takes an array of file or directory names on the command line, determines what kind of name it is, and processes it appropriately.
2. Here is a simple method which determines if a string is a valid, local, and rooted file path. Explorer says it is not a valid path, but you don't check this.

Hi Bsharper, First, you could change the regex expression to assert position at the beginning of the string A and also to assert position at the end of the string Z (if you validate a single path). This way invalid characters already present in the exclusion list ^ /:.?' ' r n will not stop the parsing process, and the match will fail as a whole. Second, you surely could add some additional invalid characters to the exclusion list.

And third: The regex expression above is mainly about formal path validity. If you need to disallow further invalid characters, please use Path.GetInvalidPathChars to get an char of invalid characters and validate the string against the array before applying the regex.

Jan 22, 2008 Hi guys, My objective is to check for the valid file path selected by the browse button of File control at the aspx side ( Javascript ).

And third: The regex expression above is mainly about formal path validity. If you need to disallow further invalid characters, please use Path.GetInvalidPathChars to get an char of invalid characters and validate the string against the array before applying the regex.

BOOL PathFileExists( In LPCTSTR pszPath ); Parameters pszPath in Type: LPCTSTR A pointer to a null-terminated string of maximum length MAXPATH that contains the full path of the object to verify. Return value Type: BOOL TRUE if the file exists; otherwise, FALSE. Call for extended error information. Remarks This function tests the validity of the path. A path specified by Universal Naming Convention (UNC) is limited to a file only; that is, server share file is permitted.

Mac Os

A UNC path to a server or server share is not permitted; that is, server or server share. This function returns FALSE if a mounted remote drive is out of service.
