I am trying to create a custom ValidationAttribute in my c# .net code. I have done a lot of searching and have code that should be working but the IsValid method is not firing as far as I can tell.
Model code:
[Required(AllowEmptyStrings = false, ErrorMessage = "required")] //[Range(2014, 2100, ErrorMessage="Please enter a valid year.")] //[RegularExpression(@"^d{4}$", ErrorMessage = "Please enter a valid year.")] [ValidYear(ErrorMessage="Please enter one >= 2014")] [Display(Name = "Exp. Year")] public string expYear { get; set; }
And this is the class in that same model:
public class ValidYearAttribute : ValidationAttribute { protected override ValidationResult IsValid(object value, ValidationContext validationContext){ return new ValidationResult("Something went wrong"); } }
I have tried googling, so, reddit, irc, and various other forums. Anyways, I am writing a todo list app in c. It generates an xml tree that looks something like this: [URL]... . The problem where I am struggling, is in the function todo_complete, I try to make the attribute of an item switch from false to true. it does it without error, but I can't make it stay that way. here is the code: [URL]...
I would like to modify attributes like modification/creation dates.The function is correctly working as if I type in "ls -al", the timestamp is correct. But when using my program to read these attributes, it returns the "real" modification/creation date. Here is the function that shows the timestamp :
Code:
time_t t = sb.st_mtime; struct tm tm = *localtime (&t); char s[32]; strftime (s, sizeof s, "%d/%m/%Y %H:%M:%S", &tm); printf ("%-14s %s", lecture->d_name, s); And here is the code for modifying the timestamps : Code: void modifyAttributes(char * file, int mtime, int atime) }
I want to use C++ regex library, to use it in my lil' CLI game. The aim is to create the template(not C++ template :)) for command(like "go north"). Then, if player writes anything that contains "go", and "north" appearing after that(examples: "go north" "please go north" "Let's go north!" "Princess, I insist that we go to the north") would all be interpreted as simple "go north". I have used a bit of regex in Linux system, but not this ECMAScript regex that C++ uses.I've checked in some online regex tester, that if I write: ".*go.*north.*" then anything I want will be matched; however, I'd like these to be specifically separated by space(the rule is: between north and go there must be at least one character: a space, so that gornorth won't be interpreted as command.).
Bonus points: if it's possible to do that without some kind of black magic, I'd like to achieve following goals:
1)Before go, there can be any amount of characters, but if there is 1 or more characters, the character just before go must be space. 2)In between go and north, there must be at least one character, space. If there are more, then characters right after go and just before north have to be spaces.
I have a multimap with over 300k entries defined like so: std::multimap<std::string, std::string> filedata;
Using the following code and std::multimap::equal_range, I am able to successfully search for a word in the multimap and get needed data:
// Data with strings. data = std::vector<std::string>(); // Get iterators to matched pairs. std::pair <std::multimap<std::string, std::string>::iterator, std::multimap<std::string, std::string>::iterator> dat = filedata.equal_range(word); // Go through each matched pair and get needed info. for (std::multimap<std::string, std::string>::iterator iter = dat.first; iter != dat.second; iter++) { data.push_back(iter->second); }
Now, I would like to search the multimap using regular expressions (EX: std::regex("[a-z][a-e]h")). What is the fastest way to do this? Example code may look like:
std::pair <std::multimap<std::string, std::string>::iterator, std::multimap<std::string, std::string>::iterator> dat = filedata.equal_range_with_regex(std::regex("" + word + ""));. Pseudo-code / algorithms will be enough.
So I need to use boost/regex for regular expressions. someone told me that it needs to be built. the first problem is boost doesn't tell you how to build it and the second is i did sudo apt-get install libboost something. I don't remember the exact name of the package. it installed but i dont know how i would build it when its installed.
and get an Iterator to the beginning of the match by
matches->at(i)->begin()
How can I get the relative position of the match within the entire target string (i.e. "Unseen University", where, in this case, the positions should be 0 and 7)??
I am using the (fairly) new STL implementation, which I just became aware of, of regexes. Seems to be an implementation of boost::regex Anyway, I have code, which I would like to use to get ALL matches within a string.
The problem, is that I dont know how to make Regex get Integers no matter what (e.g. even if an =, >,<,>=,<= sign is in front or anything) unless it is encased in a string e.g. "'s or whatever.
My current code does this:
I do not want the numbers to be highlighted if they are in a string.
I was just reviewing some code, and my eye fell on a bit of regex that's intended to parse a date/time stamp into a date and time.
The timestamp uses shorted month names. The regex had all the possible month names to match the entire pattern. If it does, it went through a 2Nd loop to convert the month name into a 1 to 12 numeric value...
This made me wonder, since the regex is already doing the work to verify the alternation, can't it at the same time tell me which of the possible alternations it matched and use that to calculate the numeric value. So basically
Code: std::regex reMonth("Some more regex stuff here (Jan|Feb|Mar|Apr|May|Jun|Jul|Aug|Sep|Oct|Nov|Dec)."); CString strTest("Some more regex stuff here Aug."); std::cmatch res; if (std::regex_match(strTest.GetString(), res, reMonth)) { //int iMonthNum = res[1].something(); // some code here that returns 8 for Aug. }
Or is there really no other way out than doing a 2nd level verification to figure out the actual month number. (The real regex is a bit more complex than this).
i found somewhere online this code that populate my listbox with file names. Now is it anyhow possible to filter those names before it gets populated by regex ?
In the MSDN, it gives an example using Regex.Matches method:
using System; using System.Text.RegularExpressions; public class Example { public static void Main() { string pattern = "a*"; string input = "abaabb"; foreach (Match m in Regex.Matches(input, pattern)) Console.WriteLine("'{0}' found at index {1}.", m.Value, m.Index);
[code]......
I am wondering if string input was an array of strings instead, how would I use Regex.Matches?
What I was thinking about doing is having the input array set to ToString(), input.ToString(), but that doesn't seem to work.
