My requirement is as follows:
I want a text box which will accept CSV values and the values can be any time of a day,i.e.,in one text box I can enter multiple clock times,separated by comma.Hour,Minutes will be separated by :.Second no required
If a.m. or p.m. can be associated it would be great[0-12 basis], otherwise 0-24 basis will be fine.
Accepted Inputs:1:00,12:45,23:59,11:34
I would like to make sure a time with correct format (HH:mm)
this is my code
bool timeCheck = true;
string[] time = ArrivalTIME.Text.Split(':');
if (time.Length > 2)
{
if (time[0].ToString()< 0 || time[0].ToString() > 23)
timeCheck = false;
if (time[1].ToString() < 0 || time[1].ToString() > 59)
timeCheck = false;
}
else
timeCheck = false;
but this code will cause some problem ArrivalTime.Text = "aa:bb" caused syntax error..
just wondering would this check done by Regex ?
Every date time format can be represented by a regular expression how can i get the a regular expression for a perticulat format?using .net API
View 3 RepliesI'm having a little trouble with using regex in linq. I want to be able to perform a search on values in my database. The goal is to insert a value into the regex and then use that to search a column in a table in my database for that term. I want it to work so that it gets all exact matches and also returns matches in which the search term is a substring of the term in the column.

how to suppress the "AM" in the gridview (template Bind("RideTimeMin", "{0:t}")? Don't tell me to use military time because the function is not "time on a clock"; it's how much time is allowed for a task (in this case the min/max hours & minutes that horses have to complete a 20 mile trail; e.g. 05:00, 05:27, etc). I'm currently accomplishing this in the "ondatabound" function by "..RTmin.Replace("AM","")". I have looked and looked at all the websites that talk about datetime formatting but have yet to find a way to do it upfront in the gridview bind statement.
View 6 RepliesI am getting taggings like the following in a string
<color> vocation </color>
<color> elation </color>
<color> sage </color>
you can notice that each tagging differs only in the wordings
vocation
elation
sage
But i want to write a code some thing like this
Regex.Replace(userAx, "<color> vocation </color>",
"<color> </color>"
so that the resulting output does not contain words at the centre.In the above code instead of giving the word vocation exclusively, i have to mention some pattern, so that it will replace all the words instead of doing it for first sentence only.How to modify my code?

I have a textbox where I accept multiple email ids separated by a comma. I then split it in my code-behind. If an email id is invalid, I change the background of it using Regex.replace, like this:
Regex.Replace(InputTxt, Search_Str, StartTag & "$1" & EndTag, RegexOptions.IgnoreCase)
My start and end tags are definned as:
"<Span class=highlight>" and "</span>"and my CSS is defined
as:.highlight { text-decoration: none; color:black; background:yellow;}This doesn't work.
How can I make this regex not accept spaces?: [0-9a-zA-Z' ']{3,}

View 7 RepliesI am trying to validate some textfields for decimal values and i am using regex to that.Here the expression that i am using currently. @"d.dthis works fine for examples 45.23, 455.345 ...But not these (45.23, 45.23abcd . its still allowing these.Looks like its only checking for the decimal text in between , start and end seems to be pretty for garbage characters.I tried putting ^ in the begining of the expression and $ in the end. But didnt make a difference.

Is Regex.Replace the best way to replace these items? I need to keep the text between the opening and closing statements as well as ensure the proper formatting to the text so doing just ReplacementText.Replace will not work. I've tried a number of different things to try and get Regex.Replace working properly but keep having different issues and different things happen. But why it's not using the the closing span for the bold statement but using the closing span for the italics is beyond me.
I have downloaded the page and I'd like to place all links into the array of strings. I'm not sure how to make the regex work. I can't uncomment the thing either because it balks at the quotes. The idea is to place each link found on the page into list. How would I handle relative links if the link found is ../ or ./? For just ./ that could be changed to / but otherwise you have to map the thing to get a full url. Also each url put into the list has to be the local domain and not an external domain.

My company has two different domains for there email
1. [URL]
2. [URL]
i need to validate a text box which captures email address and make sure that it only allows these domains so [URL] and [URL] is allowed.
I have this simple regex string to validate emails. It worked fine until someone came along with an email address that contained an ampersand:
^(['_a-zA-Z0-9-]+)(.['_a-zA-Z0-9-]+)*@([a-zA-Z0-9-]+)(.[a-zA-Z0-9-]+)*(.[a-zA-Z]{2,5})$
how I can alter this to accept the & symbol? I have tried countless ways with no success.
