  • python - checking if a user has admin privileges

    - by Matt
    Hi, I'm writing a little program as a self-learning project in Python 3.x. my idea is for the program to allow two fields of text entry to the user, and then plug the user's input into the value of two specific registry keys. What I was wondering, and something my books don't seem to cover, is if there is a simple way to make it check if the current user can access the registry. I'd rather it cleanly tell the user that he needs admin privileges than for the program to go nuts and crash because it's trying to access a restricted area. I'd like it to make this check as soon as the program launches, before the user is given any input options. What code is needed for this? thanks for the help

  • Why does my Perl regular expression only find the last occurrence?

    - by scharan
    I have the following input to a Perl script and I wish to get the first occurrence of NAME="..." strings in each of the <table>...</table> structures. The entire file is read into a single string and the regex acts on that input. However, the regex always returns the last occurrence of NAME="..." strings. Can anyone explain what is going on and how this can be fixed? Input file: ADSDF <TABLE> NAME="ORDERSAA" line1 line2 NAME="ORDERSA" line3 NAME="ORDERSAB" </TABLE> <TABLE> line1 line2 NAME="ORDERSB" line3 </TABLE> <TABLE> line1 line2 NAME="ORDERSC" line3 </TABLE> <TABLE> line1 line2 NAME="ORDERSD" line3 line3 line3 </TABLE> <TABLE> line1 line2 NAME="QUOTES2" line3 NAME="QUOTES3" NAME="QUOTES4" line3 NAME="QUOTES5" line3 </TABLE> <TABLE> line1 line2 NAME="QUOTES6" NAME="QUOTES7" NAME="QUOTES8" NAME="QUOTES9" line3 line3 </TABLE> <TABLE> NAME="MyName IsKhan" </TABLE> Perl Code starts here: use warnings; use strict; my $nameRegExp = '(<table>((NAME="(.+)")|(.*|\n))*</table>)'; sub extractNames($$){ my ($ifh, $ofh) = @_; my $fullFile; read ($ifh, $fullFile, 1024);#Hardcoded to read just 1024 bytes. while( $fullFile =~ m#$nameRegExp#gi){ print "found: ".$4."\n"; } } sub main(){ if( ($#ARGV + 1 )!= 1){ die("Usage: extractNames infile\n"); } my $infileName = $ARGV[0]; my $outfileName = $ARGV[1]; open my $inFile, "<$infileName" or die("Could not open log file $infileName"); my $outFile; #open my $outFile, ">$outfileName" or die("Could not open log file $outfileName"); extractNames( $inFile, $outFile ); close( $inFile ); #close( $outFile ); } #call main();

  • All Permutations of a string when corresponding characters are not in the same place

    - by r20rock
    I need all possible permutations of a given string such that no character should remain at the same place as in the input string. Eg. : for input "ask" Output: all possible permutaions like "ksa", "kas"... such that 'a' is not in the 1st position , 's' is not in the 2nd positions and so on... in any permutation. I only need the count of such possible permutations I can do this by generating all permutations and filtering them but I need a very efficient way of doing this. All characters in the string are "UNIQUE" Preferred language C++.

  • jQuery Validation using the class instead of the name value

    - by Matt
    Hi, I'd like to validate a form using the jquery validate plugin, but I'm unable to use the 'name' value within the html - as this is a field also used by the server app. Specifically, I need to limit the number of checkboxes checked from a group. (Maximum of 3.) All of the examples I have seen, use the name attribute of each element. What I'd like to do is use the class instead, and then declare a rule for that. html This works: <input class="checkBox" type="checkbox" id="i0000zxthy" name="salutation" value="1" /> This doesn't work, but is what I'm aiming for: <input class="checkBox" type="checkbox" id="i0000zxthy" name="i0000zxthy" value="1" /> javascript: var validator = $(".formToValidate").validate({ rules:{ "salutation":{ required:true, }, "checkBox":{ required:true, minlength:3 } } }); Is it possible to do this - is there a way of targeting the class instead of the name within the rules options? Or do I have to add a custom method? Cheers, Matt

  • What is the best data structure and algorithm for comparing a list of strings?

    - by Chiraag E Sehar
    I want to find the longest possible sequence of words that match the following rules: Each word can be used at most once All words are Strings Two strings sa and sb can be concatenated if the LAST two characters of sa matches the first two characters of sb. In the case of concatenation, it is performed by overlapping those characters. For example: sa = "torino" sb = "novara" sa concat sb = "torinovara" For example, I have the following input file, "input.txt": novara torino vercelli ravenna napoli liverno messania noviligure roma And, the output of the above file according to the above rules should be: torino novara ravenna napoli livorno noviligure since the longest possible concatenation is: torinovaravennapolivornovilligure Can anyone please help me out with this? What would be the best data structure for this?

  • Issue on passing a checkbox set to an AppEngine script through jQuery Ajax/Json

    - by Jorge
    I have a set of checkboxes with multiple choice allowed. I parse the set this way: if ($("input[name='route_day']:checked").length > 0) { $("input[name='route_day']:checked").each(function(){ if(this.value != null) route_days_hook.push(this.value); }); dataTrap.route_days = $.JSON.encode(route_days_hook); } ...and pull the whole dataTrap to an AppEngine Python script via jQuery ajax. However, the Python script just bugs. If i change dataTrap.route_days value to a string instead of the JSON encoded object, everything works fine. My question is: how can i pass a checkbox set to the script using Ajax and still be able to iterate over it on the script?

  • Dynamically/recursively building hashes in Perl?

    - by Gaurav Dadhania
    I'm quite new to Perl and I'm trying to build a hash recursively and getting nowhere. I tried searching for tutorials to dynamically build hashes, but all I could find were introductory articles about hashes. I would be grateful if you point me towards the right direction or suggest a nice article/tutorial. I'm trying to read from a file which has paths in the form of one/two/three four five/six/seven/eight and I want to build a hash like VAR = { one : { two : { three : "" } } four : "" five : { six : { seven : { eight : "" } } } } The script I'm using currently is : my $finalhash = {}; my @input = <>; sub constructHash { my ($hashrf, $line) = @_; @elements = split(/\//, $line); if(@elements > 1) { $hashrf->{shift @elements} = constructHash($hashrf->{$elements[0]}, @elements ); } else { $hashrf->{shift @elements} = ""; } return $hashrf; } foreach $lines (@input) { $finalhash = constructHash($finalhash, $lines); }

  • how is this jquery app validating the username? (3rd party script)

    - by SarmenHB
    The tutorial that I'm trying to figure out is this: http://www.position-absolute.com/articles/jquery-form-validator-because-form-validation-is-a-mess/ The username field looks like this: <input value="" class="validate[required,custom[noSpecialCaracters],length[0,20],ajax[ajaxUser]]" type="text" name="user" id="user" /> That <input> field has a class item named ajax[ajaxUser] which has its rules contained in this script (jquery.validationEngine-en.js). The snippet for that item looks like this: "ajaxUser":{ "file":"validateUser.php", "extraData":"name=eric", "alertTextOk":"* This user is available", "alertTextLoad":"* Loading, please wait", "alertText":"* This user is already taken"}, What I can't figure out at all is how its PHP page is working which is validateUser.php. Where are all those post fields coming from? I looked around and can't find a field with those names. Thanks

  • PowerShell: Read text, regex sort, write output to file and formatting

    - by Bill Hunter
    I am a Powershell novice and have run into a challenge in reading, sorting, and outputting a csv file. The input csv has no headers, the data is as follows: 05/25/2010,18:48:33,Stop,a1usak,10.128.212.212 05/25/2010,18:48:36,Start,q2uhal,10.136.198.231 05/25/2010,18:48:09,Stop,s0upxb,10.136.198.231 I use the following piping construct to read the file, sort and output to a file: (Get-Content d:\vpnData\u62gvpn2.csv) | %{,[regex]::Split($, ",")} | sort @{Expression={$[3]}},@{Expression={$_[1]}} | out-file d:\vpnData\u62gvpn3.csv The new file is written with the following format: 05/25/2010 07:41:57 Stop a0uaar 10.128.196.160 05/25/2010 12:24:24 Start a0uaar 10.136.199.51 05/25/2010 20:00:56 Stop a0uaar 10.136.199.51 What I would like to see in the output file is a similar format to the original input file with comma dilimiters: 05/25/2010,07:41:57,Stop,a0uaar,10.128.196.160 05/25/2010,12:24:24,Start,a0uaar,10.136.199.51 05/25/2010,20:00:56,Stop,a0uaar,10.136.199.51 But I can't quite seem to get there. I'm almost of the mind that I'll have to write another segment to read the newly produced file and reset its contents to the preferred format for further processing. Thoughts?

  • Ignoring unclosed tags from another <div>?

    - by Mike
    I have a website where members can input text using a limited subset of HTML. When a page is displayed that contains a user's text, if they have any unclosed tags, the formatting "bleeds" across into the next area. For example, if the user entered: Hi, my name is <b>John Then, the rest of the page will be bold. Ideally, there'd be someting I could do that would be this simple: <div contained>Hi, my name is <b>John</div> And no tags could bleed out of that div. Assuming there isn't anything this simple, how would I accomplish a similar effect? Or, is there something this easy? Importantly, I do not want to validate the user's input and return an error if they have unclosed tags, since I want to provide the "easiest" user interface possible for my users. Thanks!

  • Using asp.net mvc model binders generically

    - by Sean Chambers
    I have a hierarchy of classes that all derive from a base type and the base type also implements an interface. What I'm wanting to do is have one controller to handle the management of the entire hierarchy (as the actions exposed via the controller is identical). That being said, I want to have the views have the type specific fields on it and the model binder to bind against a hidden field value. something like: <input type="text" name="model.DerivedTypeSpecificField" /> <input type="hidden" name="modelType" value="MyDerivedType" /> That being said, the asp.net mvc model binders seem to require the concrete type that they will be creating, because of that reason I would need to create a different controller for every derived type. Has anyone does this before or know how to manipulate the model binder to behave in this way? I could write my own model binder, but I'm not wanting anything past the basic model binding behavior of assign properties and building arrays on the target type. Thanks!

  • How to hide editor-label for public property when calling EditorFor(...)?

    - by FreshCode
    When calling Html.EditorFor(m => m), where m is a public class with public properties, a hidden input and a label are displayed for properties with the [HiddenInput] attribute. How can I hide the label without making it private or creating an editor template? Example public class User { [HiddenInput] public Guid ID { get; set; } // should not be displayed in editor template public string Name { get; set; } // should be editable } Undesired result for ID property by EditorFor(...) with label <div class="editor-label"> <label for="ID">ID</label> <!-- Why is this here? --> </div> <div class="editor-field"> <input id="ID" name="ID" type="hidden" value=""> </div>

  • Conversion of DOM element selection code to jQuery

    - by Tom McDonnell
    I have a large Javascript codebase to convert to jQuery. The code is structured such that DOM elements are created in Javascript (using a library called DomBuilder), and saved to variables if they will be needed later, before being added to the DOM. Eg. var inputs = { submitConfirm: INPUT({type: 'button', value: 'Submit'}), submitCancel : INPUT({type: 'button', value: 'Cancel'}) }; document.appendChild(inputs.submitConfirm); Then later for example... inputs.submitCancel.style.display = 'none'; inputs.submitCancel.addEventListener('click', onClickSubmitCancel, false); My problem is that jQuery seems to lack a way of manipulating DOM elements directly, as opposed to selecting them first (with for example $('#submitCancel'). Can anyone suggest a way to directly translate the last two Javascript lines given above to use jQuery, given that the DOM elements are already available, and so do not need to be selected?

  • Scala: Matching optional Regular Expression groups

    - by Brian Heylin
    I'm trying to match on an option group in Scala 2.8 (beta 1) with the following code: import scala.xml._ val StatementPattern = """([\w\.]+)\s*:\s*([+-])?(\d+)""".r def buildProperty(input: String): Node = input match { case StatementPattern(name, value) => <propertyWithoutSign /> case StatementPattern(name, sign, value) => <propertyWithSign /> } val withSign = "property.name: +10" val withoutSign = "property.name: 10" buildProperty(withSign) // <propertyWithSign></propertyWithSign> buildProperty(withoutSign) // <propertyWithSign></propertyWithSign> But this is not working. What is the correct way to match optional regex groups?

  • nested columns in compass/sass

    - by corroded
    I've been studying compass and while it is a fun thing to play with and use, one thing bothers me(besides being unable to add padding as it wrecks the grid), how do I nest columns? I want to be able to do what blueprint does: nest containers like say, I have a 24-column page divided in two(17 and 7 columns). In the right part of that page(the one with 7 columns), I want to divided some elements into two(2 and 5 columns). I tried this: #main +container #main-content +column(17) +box-padding(17, 10px) :margin :right 0 #sidebar +column(7, true) +box-padding(7, 10px) That's the code for the main page. The sidebar contains a list with some labels and input fields li +container :margin :bottom 5px label +column(2) :margin :right 0 input +column(5, true) It kinda works, but inspecting the li in firebug shows that it's width is actually 950px as opposed to be just 270px since it is just 7 columns. I tried googling about nested columns but I can't seem to find any example in compass. I've also tried the wiki and the documentation to no avail.

  • Loading form values from one IFrame to another

    - by Roland
    What I want to achieve is the following. A search is made from one IFrame "the form is loaded into this frame via the src atribute of iframe" the search query is then passed to another IFrame that redirects to a url with the query eg. www.test.com/index.php?query=test Is this possible? Currently my code looks as such <iframe src="abc.php" name="iframe1"> </iframe> <iframe name="iframe2"> <?php var_dump($_GET); ?> </iframe> abc.php contains the following <form method="get" action="#" target="iframe2"> <input type="text" name="searchtype" id="searchtype" /> <input type="submit" value="submit"> </form>

  • Is there a non-blocking version of MessageBox.Show (or something like it)?

    - by Dan Tao
    Often you just want to notify the user that something has occurred, but there's really no need for any input from them. In this common scenario, I sometimes see code like this: MessageBox.Show("Something has occurred", "Something", MessageBoxButtons.OK); This code, as we all know, causes a little pop-up window to appear with only an OK button. Now here's the thing: this code blocks (the UI thread). But in the vast majority of cases, it seems to me, if you only have an OK button, there's very little need to block. (Isn't the purpose of blocking typically to receive some input from the user? And if the user's only choice is "OK," in this typical case, isn't blocking pretty pointless?) Obviously I could just write my own little form that does basically exactly what MessageBox.Show does, except that it returns nothing (no DialogResult) and doesn't block. But I was just wondering if something like this exists already that I didn't know about.
