  • Get info about Http Post field order

    - by Eugene
    Is it possible to get information about post field order in ASP.NET? I need to know whether some field was the last one or not. I know I can do it through Request.InputStream, but I’m looking for a more high level solution without manually stream parsing. Generally I’m doing testing of http post sent by my application and there is no practical usage for this in ASP.NET.

  • python: importing modules with incorrect import statements => unexhaustive info from resulting Impor

    - by bbb
    Hi there, I have a funny problem I'd like to ask you guys ('n gals) about. I'm importing some module A that is importing some non-existent module B. Of course this will result in an ImportError. This is what A.py looks like import B Now let's import A >>> import A Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/tmp/importtest/A.py", line 1, in <module> import B ImportError: No module named B Alright, on to the problem. How can I know if this ImportError results from importing A or from some corrupt import inside A without looking at the error's string representation. The difference is that either A is not there or does have incorrect import statements. Hope you can help me out... Cheers bb

  • Bash script to find a directory, list it's contents and sub-folders info

    - by lithiumion
    Hi I want to write a script that will: 1- locate folder "store" on a *nix filesystem 2- move into that folder 3- print list of contents with last modification date 4- calculate sub-folders size This folder's absolute path changes from server to server, but the folder name remains the same always. There is a config file that contains the correct path to that folder though, but it doesn't give absolute bath to it. Sample Config: Account ON DIR-Store /hdd1 Scheduled YES ?According to the config file the absolute path would be "/hdd1/backup/store/" I need the script to grep the "/hdd1" or anything beyond the word "Config-Store", add "/backup/store/" to it, move into folder "store", print list of it's contents, and calculate sub-folders size. Until now I manually edit the script on each server to reflect the path to the "store" folder. Here is a sample script: #!/bin/bash echo " " echo " " echo "Moving Into Directory" cd /hdd1/backup/store/ echo "Listing Directory Content" echo " " ls -alh echo "*******************************" sleep 2 echo " " echo "Calculating Backup Size" echo " " du -sh store/* echo "********** Done! **********" I know I could use grep cat /etc/store.conf | grep DIR-Store Just don't know how to get around selecting the path, adding the "/backup/store/" and moving ahead. Any help will be appreciated

  • Best way to save info in hash

    - by qwertymk
    I have a webpage that the user inputs data into a textarea and then process and display it with some javascript. For example if the user types: _Hello_ *World* it would do something like: <underline>Hello</underline> <b>World</b> Or something like that, the details aren't important. Now the user can "save" the page to make it something like site.com/page#_Hello_%20*World* and share that link with others. My question is: Is this the best way to do this? Is there a limit on a url that I should be worried about? Should I do something like what jsfiddle does? I would prefer not to as the site would work offline if the full text would be in the hash, and as the nature of the site is to be used offline, the user would have to first cache the jsfiddle-like hash before they could use it. What's the best way to do this?

  • Mixing regular expression and other conditional expression in a bash if statement

    - by Tassos
    I can't get around this for quite sometime now. As I read along manuals and tutorials I'm getting more confused. I want an if statement with the following logic: if [ -n $drupal_version ] && [[ "$drupal_version" =~ DRUPAL-[6-9]-[1-9][1-9] ]]; then but I can't get it to work properly. When the script is evaluated using the "bash -x ... " script construct, works ok but when is run as a regular script my expression is not evaluated (eventhough the above condition should be met the else part is run). Could you provide any help?

  • Regular expression replace in PL/pgSQL

    - by dreamlax
    If I have the following input (excluding quotes): "The ancestral territorial imperatives of the trumpeter swan" How can I collapse all multiple spaces to a single space so that the input is transformed to: "The ancestral territorial imperatives of the trumpeter swan" This is going to be used in a trigger function on insert/update (which already trims leading/trailing spaces). Currently, it raises an exception if the input contains multiple adjacent spaces, but I would rather it simply transforms it into something valid before inserting. What is the best approach? I can't seem to find a regular-expression replace function for PL/pgSQL. There is a text_replace function, but this will only collapse at most two spaces down to one (meaning three consecutive spaces will collapse to two). Calling this function over and over is not ideal.

  • Evaluating a regular expression range

    - by Dan Atkinson
    Hi there! Is there a nice way to evaluate a regular expression range, say, for a url such as http://example.com/[a-z]/[0-9].htm This would be converted into: http://example.com/a/0.htm http://example.com/a/1.htm http://example.com/a/2.htm ... http://example.com/a/9.htm ... http://example.com/z/0.htm http://example.com/z/1.htm http://example.com/z/2.htm ... http://example.com/z/9.htm I've been scratching my head about this, and there's no pretty way of doing it without going through the alphabet and looping through numbers. Thanks in advance!

  • A regular expression that will allow a string with only one Capital Letter

    - by Phoenix
    The string should be 6 - 20 characters in length. And it should contain 1 Capital letter. I can do this in code using C# string st = "SomeString" Regex rg = new Regex("[A-Z]"); MatchCollection mc = rg.Matches(st); Console.WriteLine("Total Capital Letters: " + mc.Count); if (mc.Count > 1) { return false; } But what i really want is a Regular expression that will match my string if it only contains one capital. The string can start with a common letter and should have only letters. Thanks In advance. (I did look at some of the other RegEx questions but they did not help).

  • Treetop basic parsing and regular expression usage

    - by ucint
    I'm developing a script using the ruby Treetop library and having issues working with its syntax for regex's. First off, many regular expressions that work in other settings dont work the same in treetop. This is my grammar: (myline.treetop) grammar MyLine rule line string whitespace condition end rule string [\S]* end rule whitespace [\s]* end rule condition "new" / "old" / "used" end end This is my usage: (usage.rb) require 'rubygems' require 'treetop' require 'polyglot' require 'myline' parser = MyLineParser.new p parser.parse("randomstring new") This should find the word new for sure and it does! Now I wont to extend it so that it can find new if the input string becomes "randomstring anotherstring new yetanother andanother" and possibly have any number of strings followed by whitespace (tab included) before and after the regex for rule condition. In other words, if I pass it any sentence with the word "new" etc in it, it should be able to match it. So let's say I change my grammar to: rule line string whitespace condition whitespace string end Then, it should be able to find a match for: p parser.parse("randomstring new anotherstring") So, what do I have to do to allow the string whitespace to be repeated before and after condition? If I try to write this: rule line (string whitespace)* condition (whitespace string)* end , it goes in an infinite loop. If i replace the above () with [], it returns nil In general, regex's return a match when i use the above, but treetop regex's dont. Does anyone have any tips/points on how to go about this? Plus, since there isn't much documentation for treetop and the examples are either too trivial or too complex, is there anyone who knows a more thorough documentation/guide for treetop?

  • Java (Android) regular expression to strip out HTML paragraph

    - by jackbot
    I have an Android application which grabs some data from an external XML source. I've stripped out some HTML from one of the XML elements, but it's in the format: <p class="x">Some text...</p> <p>Some more text</p> <p>Some final text</p> I want to extract the middle paragraph text, how can I do this? Would a regular expression be the best way? I don't really want to start including external HTML parsing libraries.

  • Usability standards when combining AJAX and regular POST-based form saves

    - by mcrider
    I'm working on a project where on certain pages (e.g. settings pages) we combine AJAX and regular fill-out-the-form-then-submit POST based operations. I'm curious if anyone has advice on improving the usability of such a page. One of my ideas is that when the user enters/modifies a value in a non-ajax part of the page, some sort of div would appear (say in a fashion similar to Growl) indicating that the user needs to save by pressing 'Submit' at the bottom of the page (and possibly putting up a modal dialog if the user navigates away from the page before saving, though that might be a bit too intrusive). I'm sure this type of interaction exists, but I can't find any examples.

  • Regular expression of unicode characters on string

    - by Marcus King
    I'm working in c# doing some OCR work and have extracted the text I need to work with. Now I need to parse a line using Regular Expressions. string checkNum; string routingNum; string accountNum; Regex regEx = new Regex(@"\u9288\d+\u9288"); Match match = regEx.Match(numbers); if (match.Success) checkNum = match.Value.Remove(0, 1).Remove(match.Value.Length - 1, 1); regEx = new Regex(@"\u9286\d{9}\u9286"); match = regEx.Match(numbers); if(match.Success) routingNum = match.Value.Remove(0, 1).Remove(match.Value.Length - 1, 1); regEx = new Regex(@"\d{10}\u9288"); match = regEx.Match(numbers); if (match.Success) accountNum = match.Value.Remove(match.Value.Length - 1, 1); The problem is that the string contains the necessary unicode characters when I do a .ToCharArray() and inspect the contents of the string, but it never seems to recognize the unicode characters when I parse the string looking for them. I thought strings in C# were unicode by default.

  • codeigniter: how to redirect after login to current controller (php_self in regular php)

    - by krike
    Well it's not really a problem but I check if the user exist and log them in and redirect to site/members_area, but I don't want to send the user to a specific page but i want to reload the current controller. So if I login in index/home I would like to be redirected at index/home, how should I proceed? in regular php I would put in the action to redirect to current page <?php echo $_SERVER['PHP_SELF']; ?> This is the code in the framework function validate_credentials() { $this->load->model('membership_model'); $query = $this->membership_model->validate(); if($query) // if the user's credentials validated... { $data = array( 'username' => $this->input->post('username'), 'is_logged_in' => true ); $this->session->set_userdata($data); redirect('site/members_area'); //<-- this line here should be dynamic } else // incorrect username or password { $this->index(); } }

The good part is the getting-knowledge of Azure but on the other hand it is my personal blog and i really don't wanna spend to much money on it. So do you have any idea of how the pricing works? I saw some calculator but didn't manage to understand the numbers. Thanks in advance

  • Regular Expression - capturing contents of <select>

    - by joey mueller
    I'm trying to use a regular expression to capture the contents of all option values inside an HTML select element For example, in: <select name="test"> <option value="blah">one</option> <option value="mehh">two</option> <option value="rawr">three</option> </select> I'd like to capture one two and three into an array. My current code is var pages = responseDetails.responseText.match(/<select name="page" .+?>(?:\s*<option .+?>([^<]+)<\/option>)+\s*<\/select>/); for (var c = 0; c<pages.length; c++) { alert(pages[c]); } But it only captures the last value, in this case, "three". How can I modify this to capture all of them? Thanks!

  • Regular expression to remove all text except...

    There may be an easier way, and if there is I'm all for it. However - my ASP.NET page has a TON of controls on it, and I've given them all ID's that start with underscore. I copied all the markup into Notepad++ and I'm trying to find a regular expression that will find everything but the controls and replace it with whitespace. that way I'll have a text file that has all my control names which I'll probably throw into Excel and do some string manipulation to add ".Text = " etc. Any suggestions?

  • Regular Expression find a phrase not inside an HTML tag

    - by James Buckingham
    Hi there, I'm struggling a bit with this regular expression and wondered if anyone was about to help me please? What I need to do is isolate the 1st phrase inside a string which is NOT inside an HTML tag. So the examples I have at the moment are: This is some test text about ITS for the ITS department. Also worth mentioning ABS as well I guess.ITS, ... and ... This is some ITS test text about ITS for the ITS department. Also worth mentioning ABS as well I guess So in the first example I want it to ignore the wrapped ITS and give me the ITS at the end of the 1st sentence. In the second example I want it to return the ITS at the start of the 2nd sentence. The aim is to replace these with my own custom wrapped acronym tags in a ColdFusion application I'm writing. Thanks a lot, James
