  • Bound DataGridView not updating data source

    - by Max Yaffe
    I'm trying to bind a table of structures to a DataGridView. Loading and viewing the table is working fine but I can't edit a value and get it stored back into the table. Here's what I'm doing. I have a "primitive" data type, Real defined by public struct MyReal:IMyPrimative { public Double m_Real; //... public MyReal(String val) { m_Real = default(Double); Init(val); } //... } It gets used in a structure: public struct MyReal_Record : IMyRecord { public MyReal Freq { get; set;} MyReal_Record(String[] vals) { Init(vals); } } And the structure is used to define a table using a generic Binding List public class MyTable<S> : BindingList<S> where S: struct, IMyRecord { public Type typeofS; public MyTable() { typeofS = typeof(S); // ... } This table is used as a binding source for a grid, dynamically. private void miLoadFile_Click(object sender, EventArgs e) { MyModel.Table<Real_Record> RTable = new MyModel.Table<Real_Record>(); //... Table initialized here //set up grid with virtual mode dataGridView1.DataSource = RTable; } All of this works fine and I can create RTable, initialize it and display it in a grid. The grid allows editing and has events set for CellParsing and CellFormatting which look like: private void dataGridView1_CellFormatting(object sender, DataGridViewCellFormattingEventArgs e) { if (e.DesiredType != typeof(String)) return; e.Value = e.Value.ToString(); } private void dataGridView1_CellParsing(object sender, DataGridViewCellParsingEventArgs e) { if (e.DesiredType != typeof(MyReal)) return; e.Value = new MyReal(e.Value.ToString()); e.ParsingApplied = true; this.dataGridView1.UpdateCellValue(e.ColumnIndex, e.RowIndex); } When I edit a value in a cell, I can change the text. On leaving the cell, CellParsing fires and the event handler is called. Everything seems to be correct going into the CellParsing handler. e.DesiredType is MyReal. e.Value is a string with the new value. After the new MyReal is created from the string, e.Value is set correctly. RowIndex and ColumnIndex are correct. ReadOnly is set false. However, when I leave the cell, the system restores the original value to the cell. I thought the UpdateCellValue would replace the value in the dataSource but I seem to be missing something. What did I miss? Thanks, Max

    I'm trying to create this slider http://jqueryui.com/demos/slider/#rangemax Is it possible to parametrize the max value? For ex: $("#slider-range-max").slider({ range: "max", min: 1, max: maxValue, value: 2, slide: function(event, ui) { $("#amount").val(ui.value); } }); Is it possible to pass maxValue value, when I click on something?

  • PHP Strange error "0:". Possible Object syntax problem?

    - by Michael Stone
    I'm trying to transfer a site from one hosting company to another. I was using 000webhost until the client had hosting and a domain. Now that the client has their domain and hosting, using FatCow.com, I can not for the life of me, debug my PHP code. I'm not getting any errors. I have a successful DB connection. If you procedurally display data, it works, but when I try to use my original objects, something is breaking and just returns "0:". I have all errors on. On old server where the site worked: PHP Version 5.2.11 MySQL Version: 5.0.81 On new server where I get the "0:": PHP Version 5.2.12 MySQL Version 5.0.32 I've setup a test page to test just the output of the variables with the DB connection. Below is my code: <?php error_reporting(E_ALL); ini_set('display_errors', '1'); try { $link = mysql_connect('connectionstring', 'username', 'password'); if (!$link) { die('Could not connect: ' . mysql_error()); } else{ $db = mysql_select_db('a8210422_lit'); } if($db){ include_once('admin/classes/clsPOW.php'); include_once('admin/classes/clsProviders.php'); $pow = new POW(); $prov = new Providers(); $new = $pow->getNew(); $newAr = $new->val(); $get = $prov->getAll($newAr['providerId']); $getAr = $get->val(); $img = $getAr['image']; $name = $getAr['provider']; $desc = $getAr['description']; $zip = $getAr['zip']; $web = $getAr['link']; if($zip==0){ $zip = "Unavailable"; } print $img; print $name; print $desc; print $zip; print $web; } else{ print 'fail!'; } } //catch exception catch(Exception $e) { echo 'Message: ' .$e->getMessage(); } ?>

  • jQuery: form input values turns up undefined

    - by Seerumi
    Having problem with this bit of code qith jQuery. it should pick the values from current form and then submit them, but when I try to get them with jQuery they always turn up undefined. I know the SQL results are fine since they show correctly in HTML table, so it must be my inferior javascript skills. New with jQuery and I'm at loss :( PHP/HTML: echo "<table>\n" while ($row = odbc_fetch_array($query)) { echo "<form class='catForm'>\n"; echo "<input type=hidden class='catID' name='catID' value='".$row['running_id']."'/>\n"; echo "<tr>\n"; echo "<td>".$row['running_id']."</td>\n"; echo "<td>".$row['site_id']."</td>\n"; echo "<td>".$row['main_category']."</td>\n"; echo "<td>".$row['map_name']."</td>\n"; echo "<td><input type=textfield class='bCatID' value='".$row['mapping_id']."' size=6/></td>\n"; echo "<td><input type=submit class='saveCat' value='Save'/></td>\n"; echo "<td><input type=submit class='killCat' value='Delete' /></td>\n"; echo "</tr>\n"; echo "</form>\n"; } echo "</table>"; jQuery: $(".catForm").submit(function () { var id = $(this).find('.catID').val(); var bCatID = $(this).find('.bCatID').val(); var dataString = 'id='+id+'&bCatID='+bCatID; $.ajax({ type: "POST", url: 'adminUI/bin/updateSCategories.php', dataType : 'json', data: dataString, success: function(data) { if (data.error == true) $('.failure').html("Error, save failed.").show().fadeOut(2000); if (data.error == false) $('.success').html("Saved succesfully").show().fadeOut(2000); }, error: function(XMLHttpRequest, textStatus, errorThrown) { $('.failure').html("Error, save failed.").show().fadeOut(2000); } }); return false; }); RESULT: id: undefined bCatID: undefined

    I have returned a cursor string but it contains a delimiter. The delimiter is . I have the string quest.setText(String.valueOf(c.getString(1)));I want to turn the into a new line. What is the best method to achieve this task in android. I understand there is a way to get the delimeter. I want this to achieved for each record. I can itterate through record like so. Cursor c = db.getContact(2); I tried using a string tokenizer but it doesnt seem to work. Here is the code for the tokenizer. I tested it in just plain java and it works without errors. String question = c.getString(1); // quest.setText(String.valueOf(c.getString(1))); //quest.setText(String.valueOf(question)); StringTokenizer st = new StringTokenizer(question,"<ENTER>"); //DisplayContact(c); // StringTokenizer st = new StringTokenizer(question, "=<ENTER>"); while(st.hasMoreTokens()) { String key = st.nextToken(); String val = st.nextToken(); System.out.println(key + "\n" + val); } I then tried running it in android.

  • Multiple checkbox values search javascript

    - by JV10
    I have a list of keywords, and I've created a checkbox for each. My template has a form wrapping the content, so I can't have a nested form around the checkbox list. How can I send the selected checkbox values to my search results page? The form that wraps the content doesn't have any actions or methods applied: <form id="BoostMasterForm" runat="server"> This the HTML markup of my checkbox list: <div class="checkboxes"> <ul> <li> <input type="checkbox" name="search" class="options" value="one"> <label>one</label> </li> <li> <input type="checkbox" name="search" class="options" value="two"> <label>two</label> </li> <li> <input type="checkbox" name="search" class="options" value="three"> <label>three</label> </li> </ul> <input type="submit" value="Submit"/> </div> How can I use javascript or jQuery to submit the values of the multiple checkbox selections and on submit action them to the following URL: '/imagery/image-search.aspx' The resulting URL for a search where option 1 and 3 are submitted should be: '/imagery/image-search.aspx?search=one%20three' I'm using this javascript that I found on another post, however I need it to append the form an the action and the method. My website is ASP, where this post is for a PHP site: Sending multiple checkbox options $('.options').click(function() { var selectedItems = new Array(); $(".checkboxes input:checkbox[name=search]:checked").each(function() {selectedItems.push($(this).val());}); var data = selectedItems.join('|'); $("#opts").val(data); }); If anyone can help, it'd be greatly appreciated.

  • JQuery - Pass variables to PHP script via AJAX call and then display file

    - by hfidgen
    Hiya, I'm trying to generate Outlook event files for my events, doing so on the fly as and when someone requests it by pressing a link on the page. Here's what i've got so far, but I can't find out how to get the browser to download the content which is returned. I know how I could do this if I sent everything via _GET, but I'd prefer to do it via _POST, hence I'm going down this route.. Any thoughts? Thanks! HTML / Javascript <script> $(function() { $(".button").click(function() { // validate and process form // first hide any error messages var start = $("input#start").val(); var end = $("input#end").val(); var dataString = 'start='+ start + '&end=' + end; $.ajax({ type: "POST", url: "/calendar.php", data: dataString, success: function(data) { //Need to return the file contents somehow! } }); return false; }); }); </script> <form name="calendar" method="post" action=""> <input type="hidden" name="start" id="start" value="<?php echo $start; ?>" /> <input type="hidden" name="end" id="end" value="<?php echo $end; ?>" /> <input type="submit" name="submit" class="button" id="submit_btn" value="Outlook" /> </fieldset> </form> PHP File <?php if (isset($_POST['start'])) { $start = $_POST['start']; $end = $_POST['end']; $c = header("Content-Type: text/Calendar"); $c .= header("Content-Disposition: inline; filename=calendar.ics"); $c .= "BEGIN:VCALENDAR\n"; $c .= "VERSION:2.0\n"; $c .= "PRODID:-//xxxyyyy//NONSGML //EN\n"; $c .= "METHOD:REQUEST\n"; // requied by Outlook $c .= "BEGIN:VEVENT\n"; $c .= "UID:". $start . $end ."-" .

  • a script translatable to JavaScript with callback-hell automatic avoider :-)

    - by m1uan
    I looking for "translator" for JavaScript like already is CoffeScript, which will be work for example with forEach (inspired by Groovy) myArray.forEach() -> val, idx { // do something with value and idx } translate to JavaScript myArray.forEach(function(val, idx){ // do something with value and idx }); or something more usefull... function event(cb){ foo()-> err, data1; bar(data1)-> err, data2; cb(data2); } the method are encapsulated function event(cb){ foo(function(err,data1){ bar(data1, function(err, data2) { cb(data2); }); }); } I want ask if similar "compiler" to JavaScript like this even better already doesn't exists? What would be super cool... my code in nodejs looks mostly like this :-) function dealer(cb){ async.parallel([ function(pcb){ async.watterfall([function(wcb){ first(function(a){ wcb(a); }); }, function(a, wcb){ thirt(a, function(c){ wcb(c); }); fourth(a, function(d){ // dealing with “a” as well and nobody care my result }); }], function(err, array_with_ac){ pcb(array_with_ac); }); }, function(pcb){ second(function(b){ pcb(b);}); }], function(err, data){ cb(data[0][0]+data[1]+data[0][1]); // dealing with “a” “b” and “c” not with “d” }); } but, look how beautiful and readable the code could be: function dealer(cb){ first() -> a; second() -> b; third(a) -> c; // dealing with “a” fourth(a) -> d; // dealing with “a” as well and nobody care about my result cb(a+b+c); // dealing with “a” “b” and “c” not with “d” } yes this is ideal case when the translator auto-decide, method need to be run as parallel and method need be call after finish another method. I can imagine it's works Please, do you know about something similar? Thank you for any advice;-)
