regex - regular expression to parse short urls -

-

I have a list of possible URLs on my site, such as





4
5
6

I want to be able to match all URLs like 6 and want to redirect them to


But I I do not want to redirect. 5 url

I tried to do something like this - ((*. * People | Groups) group)) \ r

Something is wrong. Any help? Thank you

You should check that this is not people Groups : 

  (group! Group) group (. *)

Right now you are seeing that regular expression What language / framework you are using by people or groups

Can not be done on the basis to make sure that you are matching the whole string, ^ and $ < / Code> Use: 

  ^ (?! People | group) (. *) $

You should also consider whether you Want to match URL, which starts with people , like http://dev.site.com/People2/ . So it can be better: 

  ^ (?? (?: People | group) (?: / | $)) (. *) $
< P> Checks that a negative match URL for the people or groups is done after the end of the URL or slash.

You want to make sure you do not match the empty string, so use . instead of . * : 

  ^ (?? (?: People | group) (?: / | $)) (. +) $

And if you want the word without any slash: 

  ^ (? (?: People | group) (?: / | $)) ([^ /] +) $

After selecting the copies of the buffer in Linux, after the text, we can click and paste the button between the mouse. I think there is a special buffer for this, I want to use it. Programming Language: C ++ Your Library: Qt Thanks. There is just one more correct answer than Paul Dixon, which answers your needs: / P > QClipboard * clipboard = QApplication :: clipboard (); CastString Selected Text = Clipboard-> Text (QClipboard :: Selection);

delphi - Mouseover hint for TChart series value -

-
I am using a TChart in Delphi 7, and I want to display charts sometime. I am using the following code to set the chain value to a database query: chart1.FreeAllSeries; Chart1.SeriesList.Clear; Chart1.AddSeries (TBarSeries.Create (self)); TBarSeries (chart1.Series [0]) BarStyle :. = BsRectGradient; Stop starting with Query 1; Executed; While EOF does not start chart1.Series [0]. Add (field 'flags' ('sum_actual_days'), Field Astrstring ('contract_no')); the upcoming; End; End; Each time (value) is now showing both the label below the bar and in a yellow rectangle above the bar. Rather than repeating the amount of label twice, I have some additional information from the query that I would like to show above the bar rather than the label (or, preferably, as a mouseover signal). Can it be done with TChart? And how ...? This can be done with a TChart using the onMouseMeave event of the chart. Something like this should start with you: Process TForm...

How to Create Master-Details view using Asp.Net MVC framework -

-
I am evaluating the Asp.Net MVC framework for my enterprise application for the past few weeks. The one thing I'm trying to achieve is the master-detail view. As it is very clear that there is no vivestate and there is no postback. For example, now I am using the product, customer, order and order details table from the Northwind database and I am using the especial MVC. I want to make master-detail view. Basically I do not have to have separate ideas (pages of other words) for order and order details. View order and order details should be included. How should I design my controller and see how to get this functionality. Thanks & amp; Regards, Burhanuddin Ghee You want to write a domain-specific view-model class Adds an order and details from its order (I'm assuming that order-> order details are 1-> n relation, not familiar with Northwind): public class command view model (Public order order); Set;} public inenemable & lt; Order deletate & gt; ...
