  • Xpath help function

    - by NA
    Hi i have a document from which i am trying to extract a date. But the problem is within the node along with the date their is some text too. Something like <div class="postHeader"> Posted on July 20, 2009 9:22 PM PDT </div> From this tag i just want the date item not the Posted on text. something like ./xhtml:div[@class = 'postHeader'] is getting everything. and to be precise, the document i have is basically a nodelist of this elements for eg i will get 10 nodes of these elements with different date values but to be worse the problem is sometime inside these tags some random other tags also pops us like anchors etc. Can i write a universal expath which will just get the date out of the div tag?

    - by Jason
    I need to create a custom route to list all the rooms in a given building. So, I want the url to look something like this: /Building/1000/Room Which would list all the rooms in Building 1000. Is this the correct mapping for the route (to call the IndexByBuilding method in RoomController)? routes.MapRoute( "RoomsByBuilding", "Building/{id}/Room", new { controller = "Room", action = "IndexByBuilding", id = "" } );

  • How to get password html helper to render password on failed validation

    - by Max Schmeling
    I have a form for creating a new account and it has a password field in it. I'm using view models to pass data to the controller action and back to the form view. When the user enters their details in, and clicks submit, if validation fails and it returns them to the same view passing back in the view model, it won't default the password to what they entered. How can I get it to do this? Or should I even try?

  • Need some help understanding a weird C behavior

    - by mike
    This part of my code works fine: #include <stdio.h> int main(){ //char somestring[3] = "abc"; int i, j; int count = 5; for((i=0) && (j=0); count > 0; i++ && j++){ printf("i = %d and j = %d\n", i, j); count--; } return 0; } The output as expected: i : 0 and j : 0 i : 1 and j : 1 i : 2 and j : 2 i : 3 and j : 3 i : 4 and j : 4 Things get weird when I uncomment the char string declaration on the first line of the function body. #include <stdio.h> int main(){ char somestring[3] = "abc"; ... } The output: i : 0 and j : 4195392 i : 1 and j : 4195393 i : 2 and j : 4195394 i : 3 and j : 4195395 i : 4 and j : 4195396 What's the logic behind this? I'm using gcc 4.4.1 on Ubuntu 9.10.

  • please help me to solve problem

    - by davit-datuashvili
    first of all this is not homework and nobody tag it as homewrok i did not understand this porblem can anybody explain me?this is not english problem it is just misunderstanding what problem say Consider the problem of neatly printing a paragraph on a printer. The input text is a sequence of n words of lengths l1 , l2 , . . . , ln , measured in characters. We want to print this paragraph neatly on a number of lines that hold a maximum of M characters each. Our criterion of “neatness” is as follows. If a given line contains words i through j , where i = j , and we leave exactly one space between words, the number of extra space characters at the end of the line is M - j + i -(k=i,k< j,k++) lk , which must be nonnegative so that the words fit on the line. We wish to minimize the sum, over all lines except the last, of the cubes of the numbers of extra space characters at the ends of lines. Give a dynamic-programming algorithm to print a paragraph of n words neatly on a printer. Analyze the running time and space requirements of your algorithm.

  • in_array() - help on what specifically would return true

    - by Kerri
    I am using in_array, and I'm trying to use it in a way where it will only return true if it's an exact match of one of the objects in the array, not just if it's "in" the array. e.g. 1. $sample_array = array('123', '234', '345'); 2. $sample_array = array('23', '34', '45'); in_array('23', $sample_array); In the above example, I would only want version 2 to return true, because it has the exact string, '23'. Version 1 returns true as well though, because the array contains instances of the string '23'. How would I get this to work so that only version 2 returns true? Am I even using the right function?

  • Statistics help on 3 choices

    - by DaveSav
    I'm working on an Android app where, at one point, the user is asked to input whether something helped. Their options are 'Yes', 'No' and 'Don't Know'; or they could choose to ignore it. This is for multiple 'somethings' over a date range. A summary view for a date range shows the percentage of 'Yes', 'No' and 'Don't Know' entered for each 'something'. I'm also showing the 'Overall Effectiveness' as the percentage of 'Yes' inputs, which I realise is incorrect. I am thinking of changing that to 'Yes' minus 'No', but that doesn't address the 'Don't Know' inputs. How would I handle the data so that 'Overall Effectiveness' represents all 3 data inputs? So, for a 'something' which has a 'Yes' of 25%, a 'No' of 25% and a 'Don't Know' of 50%, would that be an 'Overall Effectiveness' of 0% ? Or would the 'Don't Know' affect that figure at all? As an additional to that, what graph type, other that Pie, would best display all 3 data?

  • HTML/Javascript disabled and then reenabled checkbox is being POSTED

    - by NeverStopLearning
    I have a page with a checkbox that is disabled/reenabled with javascript on button click. If I never disable the checkbox then its value is correctly POSTed, however if I disable the checkbox even once it gets posted without value (posts as "name=" even when checked). I have inspected the POST value through firebug. Why does it behaves like this? Am I missing something? I ve read somewhere that disabled controls are not posted, thats OK, but this control is not disabled when the submit is clicked. I am using ASP.NET with more complex setup to test this, but essentially this is the core of the problem. The brower is FF latest. I found very similar question, however without an answer: disabled control being reenabled but still not posting back contents to server

  • Php random row help...

    - by Skillman
    I've created some code that will return a random row, (well, all the rows in a random order) But i'm assuming its VERY uneffiecent and is gonna be a problem in a big database... Anyone know of a better way? Here is my current code: $count3 = 1; $count4 = 1; //Civilian stuff... $query = ("SELECT * FROM `*Table Name*` ORDER BY `Id` ASC"); $result = mysql_query($query); while($row = mysql_fetch_array($result)) { $count = $count + 1; $civilianid = $row['Id']; $arrayofids[$count] = $civilianid; //echo $arrayofids[$count]; } while($alldone != true) { $randomnum = (rand()%$count) + 1; //echo $randomnum . "<br>"; //echo $arrayofids[$randomnum] . "<br>"; $currentuserid = $arrayofids[$randomnum]; $count3 += 1; while($count4 < $count3) { $count4 += 1; $currentarrayid = $listdone[$count4]; //echo "<b>" . $currentarrayid . ":" . $currentuserid . "</b> "; if ($currentarrayid == $currentuserid){ $found = true; //echo " '" .$found. "' "; } } if ($found == true) { //Reset array/variables... $count4 = 1; $found = false; } else { $listdone[$count3] = $currentuserid; //echo "<u>" . $count3 .";". $listdone[$count3] . "</u> "; $query = ("SELECT * FROM `*Tablesname*` WHERE Id = '$currentuserid'"); $result = mysql_query($query); $row = mysql_fetch_array($result); $username = $row['Username']; echo $username . "<br>"; $count4 = 1; $amountdone += 1; if ($amountdone == $count) { //$count $alldone = true; } } } Basically it will loop until its gets an id (randomly) that hasnt been chosen yet. -So the last username could take hours :P Is this 'bad' code? :P :(
