• jQuery Photo Search Results Pagination using AJAX and JSON

  - by Mark Richman

  I have a "photo search" page that needs to present search results in a 5x5 grid of photo thumbnails. I'd like to populate this grid using the JSON results of a jQuery $.ajax() call to my ASP.NET web service. Where I'm struggling is with pagination, where clicking [First][Prev][1][2][3]...[20][21][Next][Last] will call back again via ajax and repopulate the results with the appropriate images. So I need to find a solution to both the pagination control itself and the search results. Is there a jQuery plugin for this, or something I can easily adapt for my purposes?

• Postback of delimited text from javascript and parsing on server side

  - by Alt_Doru

  In my ASP.NET page, I have a Javascript object, like this: var args = new Object(); args.Data1 = document.getElementById("Data1").value; args.Data2 = document.getElementById("Data2").value; args.Data3 = document.getElementById("Data3").value; The object is populated on client side using user input data. I am passing the data to a C# method, through an Ajax request: someObj.AjaxRequest(argsData1 + "|" + argsData2 + "|" + argsData3) Finally, I need to obtain the data in my C# code: string data1 = [JS args.Data1] string data2 = [JS args.Data2] string data3 = [JS args.Data3] My question is what's the best solution for this? As i am concatenating bits of user input, I don't think it's best to use "|" as a delimiter. Also, it's not clear to me how to actually parse the data in my C# code to populate the three variables with the original data.

• allow only distinct values in ComboBox

  - by Ravinder Gangadher

  In my project, I am trying to populate ComboBox from DataSet. I succeeded in populating but the values inside the ComboBox are not distinct (Because it just showing the values present in DataSet). I cant bind the ComboBox to DataSet because I am adding "Select" text at first of populating the values. Here is my code. ComboBox --> cmb DataSet --> ds DataSet Column Name --> value(string) cmb.Items.Clear(); cmb.Items.Add("Select"); for (int intCount = 0; intCount < ds.Tables[0].Rows.Count; intCount++) { cmb.Items.Add(ds.Tables[0].Rows[intCount][value].ToString()); } cmb.SelectedIndex = 0; My question is how to allow distinct values (or restrict duplicate values) inside the ComboBox.

• Android/ORMLite Insert Row with ID

  - by Joe M

  I'm currently using ORMLite to work with a SQLite database on Android. As part of this I am downloading a bunch of data from a backend server and I'd like to have this data added to the SQLite database in the exact same format it is on the backend server (ie the IDs are the same, etc). So, my question to you is if I populate my database entry object (we'll call it Equipment), including Equipment's generatedId/primary key field via setId(), and I then run a DAO.create() with that Equipment entry will that ID be saved correctly? I tried it this way and it seems to me that this was not the case. If that is the case I will try again and look for other problems, but with the first few passes over the code I was not able to find one. So essentially, if I call DAO.create() on a database object with an ID set will that ID be sent to the database and if it is not, how can I insert a row with a primary key value already filled out? Thanks!

• how many dojo fliteringselect can I have on a form?

  - by Grant Collins

  I have a quick question How many dojo filteringselects can I have on a form? I have a form with 2 filteringselects on it, both getting data from different json datastores to populate the values. However only the first filteringselect is being populated, the other grabs no data. I am using Zend Framework and Zend_Dojo_Form to create the form elements for this. Many thanks. Ok looks like my code is broken somewhere then. The element that is failing in my form is: $location = new Zend_Dojo_Form_Element_FilteringSelect('location'); $location->setAutocomplete(true) ->setStoreId('countiesstore') ->setStoreType('dojo.data.ItemFileReadStore') ->setStoreParams(array('url' => $baseUrl.'/dojo/counties')) ->setAttrib('searchAttr', 'title') ->setRequired(true) ->removeDecorator('DtDdWrapper') ->removeDecorator('label') ->removeDecorator('HtmlTag') ->removeDecorator('Error'); When I go to http://localhost/dojo/counties I get the json file to read, but the element isn't populated with any data. Any ideas?

• WPF Logical Tree - bottom up vs. top down

  - by Dor Rotman

  Hello, I've read the MSDN article about the layouts pass, that states: When a node is added or removed from the logical tree, property invalidations are raised on the node's parent and all its children. As a result, a top-down construction pattern should always be followed to avoid the cost of unnecessary invalidations on nodes that have already been validated. Now lets assume I do this. Won't the users see the control tree populate itself and the layout change several times during the control creation process? I want the whole control tree to just appear completely full. Thanks!

• How to implement action in didSelectRowAtIndexPath of UITableview?

  - by Sumana Mehta

  On my view, I used to have few buttons and each button had an action associated with it. UIButton *testButton = [[UIButton alloc] initWithFrame:CGRectMake(120,300,90,90)]; [testButton setBackgroundImage:[UIImage imageNamed:@"test.jpg"] forState:UIControlStateNormal]; [testButton addTarget:self.view action:@selector(gotoProd:) forControlEvents:UIControlEventTouchUpInside]; [testButton addt [scrollView testButton]; But now I am trying to replace all those buttons with the tableview with rows. I was able to populate the rows and I know one needs to use didSelectRowAtIndexPath for handling on select event of the cell. But how can I implement action:@selector(gotoProd:) in tableviews ?? Any help will be greatly appreciated.

• Multible jquery .load() methods not running concurrently in MVC 2

  - by Boob

  In one of my aspx pages i have something like this in the head: <script type="text/javascript"> $(function() { // Jquery stuff loadStuff(); }); function loadStuff() { $('#result1').load({ source: url }); $('#result2').load({ source: url }); $('#result3').load({ source: url }); }; </script> The idea being that as the page is being displayed these loads will populate the specified divs with results from different webservices as and when the info becomes available. My problem is that this requests are being queued and being sent one at a time. However I want these to be sent at the same time and whichever returns first gets displayed first! Also if I try to kick off another request while these divs are loading the request seems to get queued after the others. How do I make these requests concurrent instead of queued? Thanks

  - by Chris

  SSIS ignoramus needing help! the situation: a temp table is populated from an excel file, which has been known to change formats at random times, that is owned by a different group. a lookup need to be performed on the temp table, tableA, to populate tableB with valid data. if the lookup results in 0 rows being returned, an email should be sent and the existing data in tableB should remain untouched. If the lookup results in a number of valid rows 0, tableB should have all rows deleted and the new records from the lookup on tableA inserted. question: what would be the best way to check if there are any valid rows and perform the appropriate action(s), depending on my results?

• How does including a .csv work in an enum?

  - by Tommy

  enum ID // IDs { ID_HEADER = 0, // ID 0 = headers #include "DATA.CSV" ID_LIMIT }; I inherited some code here..... Looking at "DATA.CSV" I see all the ID's used to populate the enum in column B, along with other data. My question: How does the enum know that it is using "column B" to retrieve it's members? There must be some other logic in the application yet I don't see it. What else should I look for? Thanks.

• AS3 Passing data between objects/classes

  - by 1337holiday

  So i a building a categorized menu of different foods. I have a class for "categories" (buttons) which essentially will return a string "salads", "drinks", etc. I now have another class "menuItems" for items within categories and this handles sizes such as "small", "med", "large", etc. My problem now is that when i return "salads", i want to invoke an array which contains all the elements of salads, send it to menuItems which will populate the menu. So far i have both the category objects and the menu object setup. I just cant seem to be able to send the data that the category object is returning and pass it to the menu object. Both of which are added to the stage as shown below: If there was a way that i could say add all these classes to one class so that they can talk to each other that would be great but i dont know how to do this. Been stuck for hours, please any help is greatly appreciated.

• MVC3 application I want javascript methods to fire on passed in route values

  - by DavieDave

  I have an MVC3 application in Visual Studio 2010. I have a view with several dropdowns that do javascript calls to populate dropdowns based on the selected value, some of which are disabled initially. That all works great with the initial state of nothing. If I however pass routevalues to the dropdowns from a redirect to this action, I do get the value set correctly but it's not enabled like it should be on the dropdown for example and when I post the form, the ones that are greyed out are not passed back on the form. How can I correct this?

• How do I declare a C# Web User Control but stop it from initializing?

  - by Scott Stafford

  I have a C#/ASP.NET .aspx page that declares two controls that each represents the content of one tab. I want a query string argument (e.g., ?tab=1) to determine which of the two controls is activated. My problem is, they both go through the initialization events and populate their child controls, wasting CPU resources and slowing the response time. Is it possible to deactivate them somehow so they don't go through any initialization? My .aspx page looks like this: <% if (TabId == 0) { %> <my:usercontroltabone id="ctrl1" runat="server" /> <% } else if (TabId == 1) { %> <my:usercontroltabtwo id="ctrl2" runat="server" /> <% } %> And that part works fine. I assumed the that <%'s would have meant the control wouldn't actually be declared and so wouldn't initialize, but that isn't so...

• New records added to DataGridView aren't displayed

  - by Ross

  I have a custom Order class, groups of which are stored in List<Order> and a DataGridView. I think the problem is in my implementation so here's how I'm using it: In the form enclosing DataGridView (as OrdersDataGrid): public partial class MainForm : Form { public static List<Order> Orders; public MainForm() { // code to populate Orders with values, otherwise sets Orders to new List<Order>(); OrdersDataGrid.DataSource = Orders; } Then in another form that adds an Order: // Save event public void Save(object sender, EventArgs e) { Order order = BuildOrder(); // method that constructs an order object from form data MainForm.Orders.Add(order); } From what I can tell from the console this is added successfully. I thought the DataGrid would be updated automatically after this since Orders has changed - is there something I'm missing? The DataGrid accepts the class since it generates columns from the members.

• PHP: Parsing of a given form input variable

  - by Jaime Cross

  How would I go about parsing incoming form data where the name changes based on section of site like: <input type="radio" name="Motorola section" value="Ask a question"> where 'Motorola section may be that, or Verizon section, or Blackberry section, etc. I do not have any control over changing the existing forms unfortunately, so must find a way to work with what is there. Basically, I need to be able to grab both the name="" data as well as its coresponding value="" data to be able to populate the email that gets sent properly.

• UITableViewController executes delate functions before network request finishes

  - by user1543132

  I'm having trouble trying to populate a UITableView with the results of a network request. It seems that my code is alright as it works perfectly when my network is speedy, however, when it's not, the function - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath- still executes, which results in a bad access error. I presume that this is because the array that the aforesaid function attempts to utilize has not been populated. This brings me to my question: Is there anyway that I can have the UITableView delegate methods delayed to avoid this? - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"AlbumsCell"; //UITableViewCell *basicCell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath]; AlbumsCell *cell = (AlbumsCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (!cell) { **// Here is where the Thread 1: EXC_BAD_ACCESS (code=2 address=0x8)** cell = [[[AlbumsCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease]; } Album *album = [_albums objectAtIndex:[indexPath row]]; [cell setAlbum:album]; return cell; }

• Best way to support large dropdowns

  - by JustAProgrammer

  Say I have a report that can be restricted by specifying some value in a dropdown. This dropdown list references a table with 30,000 records. I don't think this would be feasible to populate a dropdown with! So, what is the best way to provide the user the ability to select a value given this situation? These values do not really have categories and even if I subdivided (by having some nesting dropdown situation) by the first letter of the value, that may still leave a few thousand entries. What's the best way to deal with this?

• How to structure data... Sequential or Hierarchical?

  - by Ryan

  I'm going through the exercise of building a CMS that will organize a lot of the common documents that my employer generates each time we get a new sales order. Each new sales order gets a 5 digit number (12222,12223,122224, etc...) but internally we have applied a hierarchy to these numbers: + 121XX |--01 |--02 + 122XX |--22 |--23 |--24 In my table for sales orders, is it better to use the 5 digital number as an ID and populate up or would it be better to use the hierarchical structure that we use when referring to jobs in regular conversation? The only benefit to not populating sequentially seems to be formatting the data later on in my view, but that doesn't sound like a good enough reason to go through the extra work. Thanks

• Pre-Populated Date in Text Field

  I am trying to pre-populate a text box with today's date, but for some reason, it keeps showing today's date as 5/30/13, which is a month behind. This code should just be pulling the local time so why is it a month behind? Here is my code, can someone please tell me why the current date is off...Please help, :) var dateToday=new Date(); function loadDate(){ var today=dateToday.getMonth() + "/" +dateToday.getDate()+"/"+dateToday.getFullYear(); document.forms[0].curDate.value=today; } function orderReady(orderTime){ dateToday.setDate(dateToday.getDate()+orderTime); var ready=dateToday.getMonth()+"/" +dateToday.getDate()+"/"+dateToday.getFullYear(); document.forms[0].puDate.value=ready; } <body onload="loadDate();"> <p>Today's Date<br /> <input type="text" name="curDate" size="50" /><br />

• MVC2 JSON action, if I want to be RESTful should I allow GET, POST, or Both?

  - by Yads

  The project I'm currently working has a whole bunch of JSON actions in order to populate cascading dropdowns via ajax calls. Since they're technically Select queries and we're trying to be RESTful, we've been marking these actions with the HttpGet attributes. However by default, JsonResultdoes not allow to return results via a GET. So we've had to explicitly call Json(data, JsonRequestBehavior.AllowGet). What I'm wondering is, is this bad practice? Should we only be allowing Post requests to our Json actions? If it makes a difference, this is an enterprise application, that requires a log in to a particular environment before it can be accessed.

• Next Identity Key LINQ + SQL Server

  - by user569347

  To represent our course tree structure in our Linq Dataclasses we have 2 columns that could potentially be the same as the PK. My problem is that if I want to Insert a new record and populate 2 other columns with the PK that was generated there is no way I can get the next identity and stop conflict with other administrators who might be doing the same insert at the same time. Case: A Leaf node has right_id and left_id = itself (prereq_id) **dbo.pre_req:** prereq_id left_id right_id op_id course_id is_head is_coreq is_enforced parent_course_id and I basically want to do this: pre_req rec = new pre_req { left_id = prereq_id, right_id = prereq_id, op_id = 3, course_id = query.course_id, is_head = true, is_coreq = false, parent_course_id = curCourse.course_id }; db.courses.InsertOnSubmit(rec); try { db.SubmitChanges(); } Any way to solve my dilemma? Thanks!

• Selecting a sequence NEXTVAL for multiple rows

  - by stringpoet

  I am building a SQL Server job to pull data from SQL Server into an Oracle database through a linked server. The table I need to populate has a sequence for the name ID, which is my primary key. I'm having trouble figuring out a way to do this simply, without some lengthy code. Here's what I have so far for the SELECT portion (some actual names obfuscated): SELECT (SELECT NEXTVAL FROM OPENQUERY(MYSERVER, 'SELECT ORCL.NAME_SEQNO.NEXTVAL FROM DUAL')), psn.BirthDate, psn.FirstName, psn.MiddleName, psn.LastName, c.REGION_CODE FROM Person psn LEFT JOIN MYSERVER..ORCL.COUNTRY c ON c.COUNTRY_CODE = psn.Country MYSERVER is the linked Oracle server, ORCL is obviously the schema. Person is a local table on the SQL Server database where the query is being executed. When I run this query, I get the same exact value for all records for the NEXTVAL. What I need is for it to generate a new value for each returned record. I found this similar question, with its answers, but am unsure how to apply it to my case (if even possible): Query several NEXTVAL from sequence in one satement

• Getting a java collection of objects in Alphabetical order

  - by MichaelMcCabe

  I have a question that I dont really know where to start. So I thought i'd ask it here. Basically, I have a drop down with names in it. I want these names to be in alphabetical order. Populating the drop down happens as follows; I query a database and pull down an Id and Name, make a object called "UserList", and set the name and id variables with what I get back. I then add this object to an ArrayList. I do this over and over. I then convert this collection to an array, and pass it to my JSP page using session.setAttribute("userList", UserList); I then populate the drop down as below. <c:forEach items="${usersCompanysList}" var="c" > There probably is a simple answer but how to I sort these names?
