  • insert multiple rows into database from arrays

    - by Mark
    Hi, i need some help with inserting multiple rows from different arrays into my database. I am making the database for a seating plan, for each seating block there is 5 rows (A-E) with each row having 15 seats. my DB rows are seat_id, seat_block, seat_row, seat_number, therefore i need to add 15 seat_numbers for each seat_row and 5 seat_rows for each seat_block. I mocked it up with some foreach loops but need some help turning it into an (hopefully single) SQL statement. $blocks = array("A","B","C","D"); $seat_rows = array("A","B","C","D","E"); $seat_nums = array("1","2","3","4","5","6","7","8","9","10","11","12","13","14","15"); foreach($blocks as $block){ echo "<br><br>"; echo "Block: " . $block . " - "; foreach($seat_rows as $rows){ echo "Row: " . $rows . ", "; foreach($seat_nums as $seats){ echo "seat:" . $seats . " "; } } } Maybe there's a better way of doing it instead of using arrays? i just want to avoid writing an SQL statement that is over 100 lines long ;) (im using codeigniter too if anyone knows of a CI specific way of doing it but im not too bothered about that)

  • javascript freezeing ie8

    - by florin
    Can someone tell me why does this code freeze ie8? It is supposed to generate input fields. In firefox, safari, chrome it works, but in in8 when i press generate button it freezes var monthNames = [ "Ianuarie", "Februarie", "Martie", "Aprilie", "Mai", "Iunie", "Iulie", "August", "Septembrie", "Octombrie", "Noiembrie", "Decembrie" ]; function buildMonthlyEntries() { var startDate = new Date(document.getElementById('datastart').value); var endDate = new Date(document.getElementById('dataend').value); if (startDate == "Invalid Date" || endDate == "Invalid Date") { return null; } var monthlyEntries = document.getElementById('monthlyEntries'); monthlyEntries.innerHTML = ""; // inclusiv dataend endDate.setMonth(endDate.getMonth() + 1); // start with startDate; loop until we reach endDate for (var dt = startDate; !

  • jQuery not working as expected on HTTPS Internet explorer

    - by jat
    When I try to run my code on any other webbrowsers apart from the Internet explorer it works fine. But when I try to run the code on Internet explorer I do get an alert box saying HERE along with an Ok button. but the problem is when I click on that OK button I do not get anything. Ideally I should be getting another alert box. <!DOCTYPE html> <html> <head> <script src="js/jquery-1.4.2.min.js"></script> <script type="text/javascript"> $(document).ready(function(){ $("#submit").click(function(event) { alert("here"); $.post('process.php', {name:'test1',email:'test.com'}, function(data) { $('#results').html(data); alert(data); }); }); }); </script> </head> <body> <form name="myform" id="myform" action="" method="POST"> <label for="name" id="name_label">Name</label> <input type="text" name="name" id="name" size="30" value=""/> <br> <label for="email" id="email_label">Email</label> <input type="text" name="email" id="email" size="30" value=""/> <br> <input type="button" name="submit" id="submit" value="Submit"> </form> <div id="results"><div> </body> </html> Any help on this is very much appreciated. Edit: I found out that Internet Explorer which has HTTP works perfectly fine but not on Internet Explorer which uses HTTPS.

  • How to randomly assign a partner?

    - by David
    I asked a question some time ago about creating a random circular partner assignment using php and mysql. This is a related issue. I am working from the following code to try to give two users new, randomly selected partners: $q = "SELECT user_id FROM users WHERE partner='$quit_partner' AND status='1'"; $r = mysqli_query ($dbc, $q) or trigger_error("Query: $q\n<br />MySQL Error: " . mysqli_error($dbc)); while ($row = mysqli_fetch_array($r)) { $users[] = $row[0]; } $current = end($users); $partners = array(); foreach ($users as $user) { $partners[$user] = $current; $current = $user; $q = "UPDATE users SET partner='{$partners[$user]}' WHERE user_id='{$user}'"; mysqli_query ($dbc, $q) or trigger_error("Query: $q\n<br />MySQL Error: " . mysqli_error($dbc)); } Basically, a particular user (lets say user #4) quits the activity, leaving multiple other users without a partner (hypothetically, users # 5,6,7). I need to find out who those users are, hence the first query. Once I find them, I throw them into an array. Then comes the difficult part. I want those newly partnerless users (5,6,7) to be randomly assigned new partners from everyone in the table. The current code is flawed in that it only assigns the newly partnerless users eachother. Thanks for your help.

  • Notification 7 Days Before Payment PHP No Error Message

    - by user1858672
    So I have PHP script running on cron daily. It is suppose to check the date and send an email if it is 7 days before any payments as a reminder. I haven't used PHP in a long time so sorry if the way I did it was ridiculous or something. Thanks a lot. I would say what the problem is but I don't get any error message or anything.. <?php mysqli_connect("xxxxxx", "xxxxxxx", "xxxxxxxxx") or die(mysqli_error()); mysqli_select_db("xxxxxxxxx") or die(mysqli_error()); //Retrieve original payment dates and enter them into an array $result = mysqli_query("SELECT DateCreated FROM UserTable"); $payment_dates = mysqli_fetch_array($result); //Puts original payment date into month-day format $md_payment_dates = substr($payment_dates, 5); //Gets todays date in m-d format and adds 7 days to it $due_date = mktime(0, 0, 0, date("m"), date("d")+7); //Checks if any payment days match today's date. If there are none it script will stop. if (count(preg_grep($due_date, $md_payment_dates)) > 0) { //Retrieves usernames of users that have an invoice due. $users_to_pay = mysqli_fetch_array("SELECT Username IN UserTable WHERE DateCreated = $date"); //Notifies you via email $to = "[email protected]"; $subject = "7 Day Payment Reminder"; $message = "Hi, <br /> The following owe a payment in 7 days : " + $users_to_pay ".<br/> Their payments are due on " + $md_payment_dates " of this year."; mail($to, $subject, $message); exit(); }else{ exit(); } ?>

I.e. if user clicks on Text1, then I should open http://example.com/some-id-1 in new window and set focus at input with id some-id-1.

  • destructor being called by subclass

    - by zero
    I'm currently learning more about php objects and constructors/destructors, but i've noticed in my code that the parent class's destructor is being called twice, I thought it was because i was extending the first class to my second class and that the second class was calling it, but this is what the php docs say about that: Like constructors, parent destructors will not be called implicitly by the engine. In order to run a parent destructor, one would have to explicitly call parent::__destruct() in the destructor body. so if it is not being called by the subclass then is it because by extended the first class that i've made a reference to the parent class making it call itself twice or I'm I way off base here? the code: <?php class test{ public $test1 = "this is a test of a pulic property"; private $test2 = "this is a test of a private property"; protected $test3 = "this is a test of a protected property"; const hello = 900000; function __construct($h){ //echo 'this is the constructor test '.$h; } function x($x2){ echo ' this is fn x'.$x2; } function y(){ print "this is fn y"; } } $obj = new test("this is an \"arg\" sent to instance of test"); class hey extends test{ function hey(){ $this->x('<br>from the host with the most'); echo ' <br>from hey class'.$this->test3; } } $obj2 = new hey(); echo $obj2::hello; ?>

  • Access property of a class from within a class instantiated in the original class.

    - by Iain
    I'm not certain how to explain this with the correct terms so maybe an example is the best method... $master = new MasterClass(); $master-doStuff(); class MasterClass { var $a; var $b; var $c; var $eventProccer; function MasterClass() { $this->a = 1; $this->eventProccer = new EventProcess(); } function printCurrent() { echo '<br>'.$this->a.'<br>'; } function doStuff() { $this->printCurrent(); $this->eventProccer->DoSomething(); $this->printCurrent(); } } class EventProcess { function EventProcess() {} function DoSomething() { // trying to access and change the parent class' a,b,c properties } } My problem is i'm not certain how to access the properties of the MasterClass from within the EventProcess-DoSomething() method? I would need to access, perform operations on and update the properties. The a,b,c properties will be quite large arrays and the DoSomething() method would be called many times during the execuction of the script. Any help or pointers would be much appreciated :)

  • A loop (while/foreach) with "offset" wrapping and

    - by DarkGhostHunter
    After applying what wrapping objects using math operator, I just tought it will be over. But no. By far. <?php $faces= array( 1 => '<div class="block">happy</div>', 2 => '<div class="block">sad</div>', (sic) 21 => '<div class="block">angry</div>' ); $i = 1; foreach ($faces as $face) { echo $face; if ($i == 3) echo '<div class="block">This is and ad</div>'; if ($i % 3 == 0) { echo "<br />"; // or some other wrapping thing } $i++; } ?> In the code I have to put and ad after the second one, becoming by that the third object. And then wrap the three all in a <div class="row"> (a br after won't work out by design reasons). I thought I will going back to applying a switch, but if somebody put more elements in the array that the switch can properly wrap, the last two remaining elements are wrapped openly. Can i add the "ad" to the array in the third position? That would make things simplier, only leaving me with guessing how to wrap the first and the third, the fourth and the sixth, an so on.

  • jquery.clone() and ASP.NET Forms

    - by Jeff
    So I have a page where I would like to be able to add multiple, dynamic users to a record in a database. Here's the rough start page: <div id="records"> <div id="userRecord"> Name: <asp:TextBox runat="server" ID="objNameTextBox"></asp:TextBox> <br /> Phone Number: <asp:TextBox runat="server" ID="objPhoneNumberTextBox"></asp:TextBox> <br /> </div> </div> And the jquery: $(function () { $(".button").button().click(function (event) { addnew(); event.preventDefault(); }); }) function addnew() { $('#userRecord').clone().appendTo('#records'); } So my question is what do I use within ASP.NET to be able to poll all of the data in the form and add a unique record for each #userRecord div within the #records div? Yes - I should change the userRecord to a class - I will deal with that. This is just simple testing here. Should I look in JSON for this type of function? I'm not familiar with it but could figure it out if that is indeed my best option. Thanks for the guidance!

  • Image switch based on if a layer is visible

    - by Zuno
    I have a website that contains multiple pages as layers (not as separate HTML files). I have three images: <img src="image1.png" onclick="showlayer(1);return false;" /> <br /> <img src="image2.png" onclick="showlayer(2);return false;" /> <br /> <img src="image3.png" onclick="showlayer(3);return false;" /> When an image is clicked, it shows the relevant layer and hides the others. I want it to also change the image to image1_active.png / image2_active.png / image3_active.png depending on which layer is visible (not via the onclick event handler). Why not via the onclick event handler?... Layer 1 is set as visible by default in the CSS, so image1 needs to be image1_active.png by default too - since the user has not had to click on anything yet, this is why I need the image switch to detect the layer's visibility/display to change the image. The showlayer script is: function showlayer(n){ for(i=1;i<=3;i++){document.getElementById("layer"+i).style.display="none";document.getElementById("layer"+n).style.display="block"; }} Is it possible to adapt this script for this purpose? thank you

  • Ubuntu: how to get audio to work in both Spotify (under Wine) and Flash (in Firefox)?

    - by Jonik
    I'm running Spotify on Linux using Wine. Sound worked great (even though the sound test in winecfg failed!), until I installed alsa-oss package yesterday to get Flash sound working in Firefox. Now Spotify says: "There is a problem with your sound card. Spotify can't play music." So the question is, how to get the sound in Spotify working again, so that it also keeps working in Flash & Firefox? Tweak some ALSA settings? Spotify settings? Add/remove some packages? By the way, curiously, now that sound doesn't work in Spotify, winecfg's "Test Sound" does work! This is Ubuntu 8.04 (Hardy). Sound card / driver is probably an integrated AC'97. Please mention if any additional information about the system is needed! Update: I have Flash 10 installed (outside the packaging system, using $MOZ_PLUGIN_PATH env variable), but also had Flash 9 from flashplugin-nonfree package - and the earlier version was being used by Firefox! Based on what Mike Arthur said about Flash and alsa-oss, I removed the older Flash (flashplugin-nonfree package) and alsa-oss - and Flash sound still works, which is nice. But for some reason Spotify still doesn't play sound, even though things should now be like they were originally... Update 2: Got it working, all smoothly, finally.

  • Industrial strength cloud file storage

    - by ArthurG
    I'm looking for an industrial strength cloud file storage system. It will be used by multiple people in a startup. Our requirements: Transparent file system access: files and folders in the file system must be able transparently access (read and write) files in the cloud; files must be synchronized whenever network access is available and buffered otherwise. The system must be usable by non-technical people. Access control: we need to control who can access which files, at least on a very coarse basis. e.g., the developers will be able to access the system design documents, only the corporate folks can access recruiting documents, and only management can access certain corporate documents. Dropbox provides this via Sharing folders, but that's not adequate, if I understand it correctly, because there's no authentication of the sharing user. so the cloud service should have a notion of an account (our startup) with multiple users with distinct credentials and rights for each user Clients: it must be accessible from Macs and PCs; I would hope that it supports Linux (e.g., Ubuntu) too Security: it must provide robust security Backup: the cloud service must reliably backup the files Versioning: change version history, is a big plus, but not required Not free: we're willing to pay for the service So far, we've reviewed the following, albeit not completely thoroughly: Dropbox: has all except 1) Access control, which is provided via Sharing folders, but that's not adequate, if I understand it correctly, because there's no authentication of the sharing user. and 2) Security, as discussed here http://www.economist.com/blogs/babbage/2011/05/internet_security and here http://blog.dropbox.com/?p=821. Windows Live Mesh, has all except 1) Clients, only supporting Windows 7 and OS X. SpiderOak has all, except 1) Transparent file system access, which is only available for 1 user. Amazon Cloud, doesn't offer 1) Transparent file system access Rackspace Cloud Drive has all except 1) Access control and 2) Versioning I'll gladly include any clarifications or additional systems the community provides.

  • Mobile Friendly Websites with CSS Media Queries

    - by dwahlin
    In a previous post the concept of CSS media queries was introduced and I discussed the fundamentals of how they can be used to target different screen sizes. I showed how they could be used to convert a 3-column wide page into a more vertical view of data that displays better on devices such as an iPhone:     In this post I'll provide an additional look at how CSS media queries can be used to mobile-enable a sample site called "Widget Masters" without having to change any server-side code or HTML code. The site that will be discussed is shown next:     This site has some of the standard items shown in most websites today including a title area, menu bar, and sections where data is displayed. Without including CSS media queries the site is readable but has to be zoomed out to see everything on a mobile device, cuts-off some of the menu items, and requires horizontal scrolling to get to additional content. The following image shows what the site looks like on an iPhone. While the site works on mobile devices it's definitely not optimized for mobile.     Let's take a look at how CSS media queries can be used to override existing styles in the site based on different screen widths. Adding CSS Media Queries into a Site The Widget Masters Website relies on standard CSS combined with HTML5 elements to provide the layout shown earlier. For example, to layout the menu bar shown at the top of the page the nav element is used as shown next. A standard div element could certainly be used as well if desired.   <nav> <ul class="clearfix"> <li><a href="#home">Home</a></li> <li><a href="#products">Products</a></li> <li><a href="#aboutus">About Us</a></li> <li><a href="#contactus">Contact Us</a></li> <li><a href="#store">Store</a></li> </ul> </nav>   This HTML is combined with the CSS shown next to add a CSS3 gradient, handle the horizontal orientation, and add some general hover effects.   nav { width: 100%; } nav ul { border-radius: 6px; height: 40px; width: 100%; margin: 0; padding: 0; background: rgb(125,126,125); /* Old browsers */ background: -moz-linear-gradient(top, rgba(125,126,125,1) 0%, rgba(14,14,14,1) 100%); /* FF3.6+ */ background: -webkit-gradient(linear, left top, left bottom, color-stop(0%,rgba(125,126,125,1)), color-stop(100%,rgba(14,14,14,1))); /* Chrome,Safari4+ */ background: -webkit-linear-gradient(top, rgba(125,126,125,1) 0%, rgba(14,14,14,1) 100%); /* Chrome10+,Safari5.1+ */ background: -o-linear-gradient(top, rgba(125,126,125,1) 0%, rgba(14,14,14,1) 100%); /* Opera 11.10+ */ background: -ms-linear-gradient(top, rgba(125,126,125,1) 0%, rgba(14,14,14,1) 100%); /* IE10+ */ background: linear-gradient(top, rgba(125,126,125,1) 0%, rgba(14,14,14,1) 100%); /* W3C */ filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#7d7e7d', endColorstr='#0e0e0e',GradientType=0 ); /* IE6-9 */ } nav ul > li { list-style: none; float: left; margin: 0; padding: 0; } nav ul > li:first-child { margin-left: 8px; } nav ul > li > a { color: #ccc; text-decoration: none; line-height: 2.8em; font-size: 0.95em; font-weight: bold; padding: 8px 25px 7px 25px; font-family: Arial, Helvetica, sans-serif; } nav ul > li a:hover { background-color: rgba(0, 0, 0, 0.1); color: #fff; }   When mobile devices hit the site the layout of the menu items needs to be adjusted so that they're all visible without having to swipe left or right to get to them. This type of modification can be accomplished using CSS media queries by targeting specific screen sizes. To start, a media query can be added into the site's CSS file as shown next: @media screen and (max-width:320px) { /* CSS style overrides for this screen width go here */ } This media query targets screens that have a maximum width of 320 pixels. Additional types of queries can also be added – refer to my previous post for more details as well as resources that can be used to test media queries in different devices. In that post I emphasize (and I'll emphasize again) that CSS media queries only modify the overall layout and look and feel of a site. They don't optimize the site as far as the size of the images or content sent to the device which is important to keep in mind. To make the navigation menu more accessible on devices such as an iPhone or Android the CSS shown next can be used. This code changes the height of the menu from 40 pixels to 100%, takes off the li element floats, changes the line-height, and changes the margins.   @media screen and (max-width:320px) { nav ul { height: 100%; } nav ul > li { float: none; } nav ul > li a { line-height: 1.5em; } nav ul > li:first-child { margin-left: 0px; } /* Additional CSS overrides go here */ }   The following image shows an example of what the menu look like when run on a device with a width of 320 pixels:   Mobile devices with a maximum width of 480 pixels need different CSS styles applied since they have 160 additional pixels of width. This can be done by adding a new CSS media query into the stylesheet as shown next. Looking through the CSS you'll see that only a minimal override is added to adjust the padding of anchor tags since the menu fits by default in this screen width.   @media screen and (max-width: 480px) { nav ul > li > a { padding: 8px 10px 7px 10px; } }   Running the site on a device with 480 pixels results in the menu shown next being rendered. Notice that the space between the menu items is much smaller compared to what was shown when the main site loads in a standard browser.     In addition to modifying the menu, the 3 horizontal content sections shown earlier can be changed from a horizontal layout to a vertical layout so that they look good on a variety of smaller mobile devices and are easier to navigate by end users. The HTML5 article and section elements are used as containers for the 3 sections in the site as shown next:   <article class="clearfix"> <section id="info"> <header>Why Choose Us?</header> <br /> <img id="mainImage" src="Images/ArticleImage.png" title="Article Image" /> <p> Post emensos insuperabilis expeditionis eventus languentibus partium animis, quas periculorum varietas fregerat et laborum, nondum tubarum cessante clangore vel milite locato per stationes hibernas. </p> </section> <section id="products"> <header>Products</header> <br /> <img id="gearsImage" src="Images/Gears.png" title="Article Image" /> <p> <ul> <li>Widget 1</li> <li>Widget 2</li> <li>Widget 3</li> <li>Widget 4</li> <li>Widget 5</li> </ul> </p> </section> <section id="FAQ"> <header>FAQ</header> <br /> <img id="faqImage" src="Images/faq.png" title="Article Image" /> <p> <ul> <li>FAQ 1</li> <li>FAQ 2</li> <li>FAQ 3</li> <li>FAQ 4</li> <li>FAQ 5</li> </ul> </p> </section> </article>   To force the sections into a vertical layout for smaller mobile devices the CSS styles shown next can be added into the media queries targeting 320 pixel and 480 pixel widths. Styles to target the display size of the images in each section are also included. It's important to note that the original image is still being downloaded from the server and isn't being optimized in any way for the mobile device. It's certainly possible for the CSS to include URL information for a mobile-optimized image if desired. @media screen and (max-width:320px) { section { float: none; width: 97%; margin: 0px; padding: 5px; } #wrapper { padding: 5px; width: 96%; } #mainImage, #gearsImage, #faqImage { width: 100%; height: 100px; } } @media screen and (max-width: 480px) { section { float: none; width: 98%; margin: 0px 0px 10px 0px; padding: 5px; } article > section:last-child { margin-right: 0px; float: none; } #bottomSection { width: 99%; } #wrapper { padding: 5px; width: 96%; } #mainImage, #gearsImage, #faqImage { width: 100%; height: 100px; } }   The following images show the site rendered on an iPhone with the CSS media queries in place. Each of the sections now displays vertically making it much easier for the user to access them. Images inside of each section also scale appropriately to fit properly.     CSS media queries provide a great way to override default styles in a website and target devices with different resolutions. In this post you've seen how CSS media queries can be used to convert a standard browser-based site into a site that is more accessible to mobile users. Although much more can be done to optimize sites for mobile, CSS media queries provide a nice starting point if you don't have the time or resources to create mobile-specific versions of sites.

  • How to solve "403 Forbidden" on CentOS6 with SELinux Disabled?

    - by André
    I have a machine on Linode that is driving me crazy. Linode does not have SELinux on CentOS6... I'm trying to configure to put my website in "/home/websites/public_html/mysite.com/public" As I don´t have SELinux enable, how can I avoid the "403 Forbidden" that I get when trying to access the webpage?

  • problem with sqldatasource and data binding

    - by Alexander
    I am trying to pull out data from the table I had from the database according to the id which is passed from the URL. However I always get data from id= 1? Why? FYI I took this code directly from the ClubWebsite starter kit and copy and paste it to my project to make several changes, the ClubWebsite one worked fine.. but this one doesn't and can't find any reason why because they both looked exactly the same. <%@ Page Title="" Language="C#" MasterPageFile="~/MasterPage.master" AutoEventWireup="true" CodeFile="Events_View.aspx.cs" Inherits="Events_View" %> <asp:Content ID="Content1" ContentPlaceHolderID="head" Runat="Server"> </asp:Content> <asp:Content ID="Content2" ContentPlaceHolderID="splash" Runat="Server"> <div id="splash4">&nbsp;</div> </asp:Content> <asp:Content ID="Content3" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server"> <div id="content"> <div class="post"> <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:ClubDatabase %>" SelectCommand="SELECT dbo.Events.id, dbo.Events.starttime, dbo.events.endtime, dbo.Events.title, dbo.Events.description, dbo.Events.staticURL, dbo.Events.address FROM dbo.Events"> <SelectParameters> <asp:Parameter Type="Int32" DefaultValue="1" Name="id"></asp:Parameter> </SelectParameters> </asp:SqlDataSource> <asp:FormView ID="FormView1" runat="server" DataSourceID="SqlDataSource1" DataKeyNames="id" AllowPaging="false" Width="100%"> <ItemTemplate> <h2> <asp:Label Text='<%# Eval("title") %>' runat="server" ID="titleLabel" /> </h2> <div> <br /> <p> <asp:Label Text='<%# Eval("address") %>' runat="server" ID="addressLabel" /> </p> <p> <asp:Label Text='<%# Eval("starttime","{0:D}") %>' runat="server" ID="itemdateLabel" /> <br /> <asp:Label Text='<%# ShowDuration(Eval("starttime"),Eval("endtime")) %>' runat="server" ID="Label1" /> </p> </div> <p> <asp:Label Text='<%# Eval("description") %>' runat="server" ID="descriptionLabel" /> </p> </ItemTemplate> </asp:FormView> <div class="dashedline"> </div> </div> </div> </asp:Content> using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; using System.Data.SqlClient; using System.Configuration; using System.Data; public partial class Events_View : System.Web.UI.Page { const int INVALIDID = -1; protected void Page_Load(object sender, System.EventArgs e) { SqlDataSource1.SelectParameters["id"].DefaultValue = System.Convert.ToString(EventID); } public int EventID { get { int m_EventID; object id = ViewState["EventID"]; if (id != null) { m_EventID = (int)id; } else { id = Request.QueryString["EventID"]; if (id != null) { m_EventID = System.Convert.ToInt32(id); } else { m_EventID = 1; } ViewState["EventID"] = m_EventID; } return m_EventID; } set { ViewState["EventID"] = value; } } protected void FormView1_DataBound(object sender, System.EventArgs e) { DataRowView view = (DataRowView)(FormView1.DataItem); object o = view["staticURL"]; if (o != null && o != DBNull.Value) { string staticurl = (string)o; if (staticurl != "") { Response.Redirect(staticurl); } } } protected string ShowLocationLink(object locationname, object id) { if (id != null && id != DBNull.Value) { return "At <a href='Locations_view.aspx?LocationID=" + Convert.ToString(id) + "'>" + (string)locationname + "</a><br/>"; } else { return ""; } } protected string ShowDuration(object starttime, object endtime) { DateTime starttimeDT = (DateTime)starttime; if (endtime != null && endtime != DBNull.Value) { DateTime endtimeDT = (DateTime)endtime; if (starttimeDT.Date == endtimeDT.Date) { if (starttimeDT == endtimeDT) { return starttimeDT.ToString("h:mm tt"); } else { return starttimeDT.ToString("h:mm tt") + " - " + endtimeDT.ToString("h:mm tt"); } } else { return "thru " + endtimeDT.ToString("M/d/yy"); } } else { return starttimeDT.ToString("h:mm tt"); } } }
