  • How do I obtain selected rows in a DataGridView from different pages

    - by cmrhema
    Hi, I have a windows forms DataGridView, where I have data and a checkbox for each row. I will select check box for a particular row and all the selected rows will be populated in another page. if (grdEmp.Rows.Count > 0) { var selectedEmpIDs= from DataGridViewRow coll in grdEmp.Rows where Convert.ToBoolean(coll.Cells["Select"].Value) == true select coll; if (selectedEmpIDs.Count() > 0) { foreach (DataGridViewRow row in selectedEmpIDs) { selectedEmp+= row.Cells["EmpId"].Value + ","; } } } This works good only for one page. When I navigate to another page, and click the selected rows, the previous one goes off. How do I resolve it. Thanks cmrhema Note :Sorry for the confusion, When I meant it works good for a page, I meant paging. I think I need to add more inputs, There are 10 pages in the gridview. I select the first record from each page of the gridview, one after another by clicking next page( Page next button). But only the record that was selected the last is getting displayed and others and ignored off. What could be the prblm

  • Post JSON array to mvc controller

    - by Yustme
    I'm trying to post a JSON array to a mvc controller. But no matter what i try, everything is 0 or null. I have this table that contains textboxes. I need from all those textboxes it's ID and value as an object. This is my java code: $(document).ready(function () { $('#submitTest').click(function (e) { var $form = $('form'); var trans = new Array(); var parameters = { TransIDs: $("#TransID").val(), ItemIDs: $("#ItemID").val(), TypeIDs: $("#TypeID").val(), }; trans.push(parameters); if ($form.valid()) { $.ajax( { url: $form.attr('action'), type: $form.attr('method'), data: JSON.stringify(parameters), dataType: "json", contentType: "application/json; charset=utf-8", success: function (result) { $('#result').text(result.redirectTo) if (result.Success == true) { return fase; } else { $('#Error').html(result.Html); } }, error: function (request) { alert(request.statusText) } }); } e.preventDefault(); return false; }); }); This is my view code: <table> <tr> <th>trans</th> <th>Item</th> <th>Type</th> </tr> @foreach (var t in Model.Types.ToList()) { { <tr> <td> <input type="hidden" value="@t.TransID" id="TransID" /> <input type="hidden" value="@t.ItemID" id="ItemID" /> <input type="hidden" value="@t.TypeID" id="TypeID" /> </td> </tr> } } </table> This is the controller im trying to receive the data to: [HttpPost] public ActionResult Update(CustomTypeModel ctm) { return RedirectToAction("Index"); } What am i doing wrong?

  • How to defer execution of an Event on each item in a collection until iteration of collection is com

    - by Metro Smurf
    Of Note: This is more of a curiosity question than anything else. Given a List<Window> where each window has an event attached to the Close Event which removes the window from the collection, how could you use delegates / events to defer the execution of the Close Event until the collection has been iterated? For example: public class Foo { private List<Window> OpenedWindows { get; set; } public Foo() { OpenedWindows = new List<Window>(); } public void AddWindow( Window win ) { win.Closed += OnWindowClosed; OpenedWindows.Add( win ); } void OnWindowClosed( object sender, EventArgs e ) { var win = sender as Window; if( win != null ) { OpenedWindows.Remove( win ); } } void CloseAllWindows() { // obviously will not work because we can't // remove items as we iterate the collection // (the close event removes the window from the collection) OpenedWindows.ForEach( x => x.Close() ); // works fine, but would like to know how to do // this with delegates / events. while( OpenedWindows.Any() ) { OpenedWindows[0].Close(); } } } Specifically, within the CloseAllWindows() method, how could you iterate the collection to call the close event, but defer the event being raised until the collection has been completely iterated?

  • Striped table rows in ASP.NET MVC (without using jQuery or equivalent)

    - by Richard Ev
    When using an ASP.NET WebForms ListView control to display data in an HTML table I use the following technique in to "stripe" the table rows: <ItemTemplate> <tr class="<%# Container.DisplayIndex % 2 == 0 ? "" : "alternate" %>"> <!-- table cells in here --> </tr> </ItemTemplate> With the following CSS: tr.alternate { background-color: #EFF5FB; } I have just gone through the ASP.NET MVC Movie Database Application tutorial and learnt that in MVC-land table rows can be (must be?) constructed as follows: <% foreach (var item in Model) { %> <tr> <td> <%= Html.Encode(item.Title) %> </td> <!-- and so on for the rest of the table cells... --> </tr> <% } %> What can I add to this code to stripe the rows of my table? Note: I know that this can be done using jQuery, I want to know if it can be done another way. Edit If jQuery (or equivalent) is in your opinion the best or most appropriate post, I'd be interested in knowing why.

  • Search and remove an element in mulit-dimentional array in php depending on a criteria

    - by Nadeem
    I've a simple question about multi-dim array, I want to remove any redundent element let's say in my case, [serviceMethod] => PL is coming 2 times, I want to search 'PL' with respect of [APIPriceTax] if an element has a lower price I want to keep it and remove the other one in array Array ( [0] => Array ( [carrierIDs] => 150 [serviceMethod] => CP [APIPriceTax] => 30.63 [APIPriceWithOutTax] 28.32 [APIServiceName] => Xpresspost USA [APIExpectedTransitDay] => 2 ) [1] => Array ( [carrierIDs] => 155 [serviceMethod] => PL [APIPriceTax] => 84.13 [APIPriceWithOutTax] => 73.8 [APIServiceName] => PurolatorExpressU.S. [APIExpectedTransitDay] => 1 ) [2] => Array ( [carrierIDs] => 164 [serviceMethod] => PL [APIPriceTax] => 25.48 [APIPriceWithOutTax] => 22.35 [APIServiceName] => PurolatorGroundU.S. [APIExpectedTransitDay] => 3 ) ) This is my pseudo code: Where $carrierAddedToList is the actual array $newCarrierAry = function($carrierAddedToList) { $newArray = array(); foreach($carrierAddedToList as $cV => $cK) { if( !in_array($cK['serviceMethod'],$newArray) ) { array_push($newArray, $cK['serviceMethod']); } } return $newArray; } ; print_r($newCarrierAry($carrierAddedToList));

  • Reference problem when returning an object from array in PHP

    - by avastreg
    I've a reference problem; the example should be more descriptive than me :P I have a class that has an array of objects and retrieve them through a key (string), like an associative array: class Collection { public $elements; function __construct() { $this->elements = array(); } public function get_element($key) { foreach($this->elements as $element) { if ($element->key == $key) { return $element; break; } } return null; } public function add_element ($element) { $this->elements[] = $element; } } Then i have an object (generic), with a key and some variables: class Element { public $key; public $another_var; public function __construct($key) { $this->key = $key; $this->another_var = "default"; } } Now, i create my collection: $collection = new Collection(); $collection->add_element(new Element("test1")); $collection->add_element(new Element("test2")); And then i try to change variable of an element contained in my "array": $element = $collection->get_element("test1"); $element->another_var = "random_string"; echo $collection->get_element("test1")->another_var; Ok, the output is random_string so i know that my object is passed to $element in reference mode. But if i do, instead: $element = $collection-get_element("test1"); $element = null; //or $element = new GenericObject(); $element-another_var = "bla"; echo $collection-get_element("test1")-another_var; the output is default like if it lost the reference. So, what's wrong? I have got the references to the variables of the element and not to the element itself? Any ideas?

  • How to check the correct radio button.

    - by MrW
    I have a Table containing some information that I need. All these rows also contains a column with a radio button in it so that the user is suppose to be able to check one of the rows as default. When I'm bringing the data back from the DB and want to select the one that's currentlly the default one. <% foreach (var item in (IEnumerable<Locale>) ViewData["Locales"]) { %> <tr> <td> <%= Html.Encode(item.Language.Name) %> </td> <td> <input type="radio" id="defaultLocale" name="defaultLocele" value="on" checked="<%= item.Default == false ? "false" : "true" %>" /> </td> I've also tried to do this: <input type="radio" id="defaultLocale" name="defaultLocele" value="on" checked="<%=item.Default == false ? "" : "checked" %>" /> but nothing seems to do the right thing. I always end up with having the last row in checked, which it isn't for sure.

  • Spreadsheet_Excel_Writer large data output is damaged

    - by dr3w
    I use Spreadsheet_Excel_Writer to generate .xls file and it works fine until I have to deal with a large amount of data. On certain stage it just writes some nonsense chars and quits filling certain columns. However some columns are field up to the end (generally numeric data) I'm not quite sure how the xls document is formed: row by row, or col by col... Also it is obviously not an error in a string, because when i cut out some data, the error appears a little bit further. I think there is no need in all of my code here are some essentials $filename = 'file.xls'; $workbook = & new Spreadsheet_Excel_Writer(); $workbook->setVersion(8); $contents =& $workbook->addWorksheet('Logistics'); $contents->setInputEncoding('UTF-8'); $workbook->send($filename); //here is the part where I write data down $contents->write(0, 0, 'Field A'); $contents->write(0, 1, 'Field B'); $contents->write(0, 2, 'Field C'); $ROW=1; foreach($ordersArr as $key=>$val){ $contents->write($ROW, 0, $val['a']); $contents->write($ROW, 1, $val['b']); $contents->write($ROW, 2, $val['c']); $ROW++; } $workbook->close();

  • Determine if a directory is empty, delete it if it is and delete that directroy name from a separate list. C-shell

    - by Kg123
    I have a directory named STA. Within that directory are about 600 other directories that have the format hh:mm:ss (for example 00:01:34). Within each of these sub-directories should be three files. I also have a file, 'waveformlist', (contained within STA) which is a list of all of these sub-directories i.e.: 00:01:34 00:02:35 etc. A lot of the sub-directories do not contain these three files and are instead empty. I want to run a C-shell script to go through every sub directory and check if it is empty. If it is empty I want to delete that sub directory from the main directory STA, and also remove that sub-directory name from the list 'waveformlist'. Below is my script so far. It does not recognize when the sub-directory is empty or not and does not like the rm $dir line. Also, I do not know how to go and remove the sub-directory name from 'waveformlist'. #!/bin/csh echo "Enter name of station folder to apply filter to as 'STA' e.g. APZ:" set ans = $< cd $ans set c=0 foreach dir (*:*) if ("${c}" == 0) then echo "Empty directory:" $dir rm $dir else echo ${dir} "has files" endif end I hope I have been clear enough. Thank you.

  • How to pass a parameter in a Javascript confirm function?

    - by Miles M.
    I have something like that in my code: <?php foreach($clients as $client): ?> <tr class="tableContent"> <td onclick="location.href='<?php echo site_url('clients/edit/'.$client->id ) ?>'"><?php echo $client->id ?></td> <td><a class='Right btn btn-danger' onClick="ConfirmMessage('client', <?php $client->id ?>,'clients')"> <i class="icon-remove-sign icon-white"></i> </a></td> </tr> <?php endforeach ?> that's actually the view. So when the user click on the delete button (thr one with the btn-danger class) I'd like him to confirm his choice with a javascript confirmation box message. You can find that script in the header <script> function ConfirmMessage(type, id, types) { if (confirm("Are you sure you want to delete this ",type," ?")) { // Clic sur OK document.location.href='<?php echo site_url(); ?>',types,'/delete/',id; } } </script> So here is my question: I would like the $type to be replaced by a paramenter (like client, article, post .. ) that I'll pass to the function. And i would like to get the $client-id parameter as well. I'm bad in javascript and as you already have guess, It is obviously not working at all.

  • Generating random thumbnails with PHP+FFMPEG

    - by MrGhost
    I am trying to generate thumbnails from movies using FFMPEG and the FFMPEG-PHP extension. My script works OK however takes 20 minutes just to generate 5-10 thumbnails! The script works by generating random numbers which are used as frame numbers later. All numbers generated are within the movies frame count. Can you work out why this script is taking 20 mins to finish? <?php //Dont' timeout set_time_limit(0); //Load the file (This can be any file - still takes ages) $mov = new ffmpeg_movie('1486460.mp4'); //Get the total frames within the movie $total_frames = $mov->getFrameCount(); //Loop 5 times to generate random frame times for ($i = 1; $i <= 5; ) { // Generate a number within 200 and the total number of frames. $frame = mt_rand(200,$total_frames); $getframe = $mov->getFrame($frame); // Check if the frame exists within the movie // If it does, place the frame number inside an array and break the current loop if($getframe){ $frames[$frame] = $getframe ; $i++; } } //For each frame found generate a thumbnail foreach ($frames as $key => $getframe) { $gd_image = $getframe->toGDImage(); imagejpeg($gd_image, "images/shot_".$key.'.jpeg'); imagedestroy($gd_image); echo $key.'<br/>'; } ?> The script SHOULD be generating frame numbers which are valid? Anything within START - END should be valid frame numbers? Yet the loop takes ages!

  • problem calculating the position using php

    - by LiveEn
    I have a function below which gets name from a site. Below is the partial code, not complete. The values are passed thru a for loop using php. function funct($$name,$page) { $url="http://testserver.com/client?list=$name&page=$page"; $ch=curl_init(); curl_setopt($ch,CURLOPT_URL,url); $result=curl_exec($ch); $dom = new DOMDocument(); @$dom->loadHTML($result); $xpath=new DOMXPath($dom); $elements = $xpath->evaluate("//div"); foreach ($elements as $element) { $name = $element->getElementsByTagName("name")->item(0)->nodeValue; $position=$position +1; echo $name.$position; } } The code works fine but when i get a name i need to add a position and for each name it will be incremented by 1 to make it contentious. But when the values for the pages are passed, for an example when i move from page 1 to page 2. the count starts again from first, next page... same problem. How can i make it continues on every page?

  • Retrieve POST data without knowing exact number of fields

    - by James
    Hi all! I'm creating an online poll from scratch which will be held in a database. I'm working on getting a system set up so someone can create a new poll. I will be having the user fill out a simple HTML form with the Questions and Answers (there may be several answers). The user will be able to add multiple questions and multiple answers for each question. As the total number of questions and answers will be decided by the user, I need to create some clever PHP to cater for this - however many there are. When dealing with a static number of questions, it's simple. But I'm having trouble thinking of a way to get all the POST data into individual PHP variables so I can process them. I was thinking of using a foreach loop, anyone got any ideas? Sorry for the long winded description! If anyone needs anything clarified, I'd be happy to do so. My problem is that I can't get my head around how to deal with the POST values when I don't know exactly which element of the array will contain what. If things were static with a set number of questions and answers, I'd know $_POST[0] was Question1, etc Thank you! =)

  • Extended Zend_Db_Table_Row_Abstract does not return values

    - by WesleyE
    Hi, I'm quite new to Zend and the database classes from it. I'm having problems mapping a Zend_Db_Table_Row_Abstract to my rows. The problem is that whenever I try to map it to a class (Job) that extends the Zend_Db_Table_Row_Abstract class, the database data is not receivable anymore. I'm not getting any errors, trying to get data simply returns null. Here is my code so far: Jobs: class Jobs extends Zend_Db_Table_Abstract { protected $_name = 'jobs'; protected $_rowsetClass = "Job"; public function getActiveJobs() { $select = $this->select()->where('jobs.jobDateOpen < UNIX_TIMESTAMP()')->limit(15,0); $rows = $this->fetchAll($select); return $rows; } } Job: class Job extends Zend_Db_Table_Row_Abstract { public function getCompanyName() { //Gets the companyName for this row (Is on another table), just for example } } Controller: $oJobs = new Jobs(); $aActiveJobs = $oJobs->getActiveJobs(); foreach ($aActiveJobs as $value) { var_dump($value->jobTitle); } When I remove the "protected $_rowsetClass = "Job";" line, so that the table row is not mapped to my own class, I get all the jobTitles perfectly. What am I doing wrong here? Thanks in advance, Wesley

  • Meaning of NEXT in Linked List creation in perl

    - by seleniumnewbie
    So I am trying to learn Linked Lists using Perl. I am reading "Mastering Algorithms with Perl" by Job Orwant. In the book he explains how to create a linked list I understand most of it, but I just simply fail to understand the command/index/key NEXT in the second last line of the code snippet. $list=undef; $tail=\$list; foreach (1..5){ my $node = [undef, $_ * $_]; $$tail = $node; $tail = \${$node->[NEXT]}; # The NEXT on this line? } What is he trying to do there? Isn $node a scalar, which stores the address of the unnamed array. Also even if we are de-referencing $node, should we not refer to the individual elements by an index number example (0,1). If we do use "NEXT" as a key, is $node a reference to a hash? I am very confused. Something in plain English will be highly appreciated.

  • Require reasonably random results from an SQL SELECT query within a Joomla article (Cache enabled)

    - by Shrinivas
    Setup: Joomla website on LAMP stack I have a MySQL table containing some records, these are queried by a simple SELECT on the Joomla article, as pasted below. This specific Joomla website has Caching turned on in Joomla's Global Configuration. I need to randomize the order in which I display the resultset, each time the page is loaded. Regular php/mysql would offer me two approaches for this: 1. use 'order by RAND()' or any of a number of methods to allow a SELECT query to return reasonably random results. 2. once php gets the result from the SELECT into an array, shuffle the array to get a reasonably random order of array items. However, as this Joomla instance has Caching turned ON in its Global Configuration, either of the above approaches fails. The first time I load the page the order is randomized, however any further reloads do not cause the order to change, as the page is delivered from cache. The instant the Cache is disabled, both approaches (shuffle/order by rand) work perfectly. What am I missing? How do I override the Global Cache for this specific article? A very simple requirement, that is met by both php and mysql reasonably well, is blocked by the Joomla Cache that I cannot turn off. The php that returns results from the database. <pre> $db = JFactory::getDBO(); $select = "SELECT id FROM jos_mytable;"; //order by RAND() $db->setQuery($select); echo $db->getQuery(); //Show me the Query! $rows = $db->loadObjectList(); //shuffle($rows); foreach($rows as $row) { echo "$row->id"; }

  • .NET: Calling GetInterface method of Assembly obj with a generic interface argument

    - by Khnle
    I have the following interface: public interface PluginInterface<T> where T : MyData { List<T> GetTableData(); } In a separate assembly, I have a class that implements this interface. In fact, all classes that implement this interface are in separate assemblies. The reason is to architect my app as a plugin host, where plugin can be done in the future as long as they implement the above interface and the assembly DLLs are copied to the appropriate folder. My app discovers the plugins by first loading the assembly and performs the following: List<PluginInterface<MyData>> Plugins = new List<PluginInterface<MyData>>(); string FileName = ...;//name of the DLL file that contains classes that implement the interface Assembly Asm = Assembly.LoadFile(Filename); foreach (Type AsmType in Asm.GetTypes()) { //Type type = AsmType.GetInterface("PluginInterface", true); // Type type = AsmType.GetInterface("PluginInterface<T>", true); if (type != null) { PluginInterface<MyData> Plugin = (PluginInterface<MyData>)Activator.CreateInstance(AsmType); Plugins.Add(Plugin); } } The trouble is because neither line where I am getting the type as by doing Type type = ... seems to work, as both seems to be null. I have the feeling that the generic somehow contributes to the trouble. Do you know why?

  • Easier way to populate form data and validation data in Code Igniter?

    - by John
    I'm new to code igniter. I'm following the form validation tutorial found at: http://www.codeignitor.com/user_guide/libraries/validation.html I find I am typing too much in the view to get the form to re-populate. For example, here's what one of my INPUT fields look like: <input type="text" name="email" value="<?=$this->validation->email ? $this->validation->email : $array_db_values['email'] ?>" /> Basically, when the form first loads, it should show a value from the database. If the user alters the value and it fails validation, then the form should post the erroneously submitted value. Does code igniter have a "cleaner" way of rendering this kind of output? Otherwise, I'm going to do something like this in my controller: $array_db_values = getdbresults(); if($_POST['submit']) foreach($_POST as $key=>$val) $array_db_values[$key] = $val; That way, if postback data exists, it will always override database values. Then input fields in my view can simply be: <input type="text" name="email" value="<?=$array_db_values['email'] ?>" /> Is there a better/native CI way to handle this scenario?

    I have this extension checker: $upload_name = "file"; $max_file_size_in_bytes = 8388608; $extension_whitelist = array("jpg", "gif", "png", "jpeg"); /* checking extensions */ $path_info = pathinfo($_FILES[$upload_name]['name']); $file_extension = $path_info["extension"]; $is_valid_extension = false; foreach ($extension_whitelist as $extension) { if (strcasecmp($file_extension, $extension) == 0) { $is_valid_extension = true; break; } } if (!$is_valid_extension) { echo "{"; echo "error: 'ext not allowed!'\n"; echo "}"; exit(0); } And then i added this: if (exif_imagetype($_FILES[$upload_name]['name']) != IMAGETYPE_GIF OR exif_imagetype($_FILES[$upload_name]['name']) != IMAGETYPE_JPEG OR exif_imagetype($_FILES[$upload_name]['name']) != IMAGETYPE_PNG) { echo "{"; echo "error: 'This is no photo..'\n"; echo "}"; exit(0); } As soon when I added this to my imageupload function, the function stops working. I dont get any errors, not even the one i made myself "this is no photo", what could be wrong? Just checked with my host. They support the function exif_imagetype()
