• How to update a table row with save button using .ajax

  - by Randall

  I have a table which has one row and only one cell will be editable. I have accomplished this with the following code. $("td#effEndDate").click(function() { if (!$(this).hasClass("edit")) { var value = jQuery.trim($(this).html()); $(this).html("<input id=\"txtEdit\" type=\"text\" value=\"" + value + "\" />"); $(this).addClass("edit"); $("#txtEdit").focus(); } }); Now this is the part where i'm stuck. After the field is updated a save button must be clicked to call the proper .ajax method to update the database. But how can I compare the previous value to the current value on a button press? Since i'm not using the onblur property where I could have saved the old value and passed it to the update function.

• Access: Data Type Mismatch using boolean function in query criteria

  - by BenV

  I have a VBA function IsValidEmail() that returns a boolean. I have a query that calls this function: Expr1: IsValidEmail([E-Mail]). When I run the query, it shows -1 for True and 0 for False. So far so good. Now I want to filter the query to only show invalid emails. I'm using the Query Designer, so I just add a value of 0 to the Criteria field. This gives me a "Data Type Mismatch" error. So does "0" (with quotes) and False. How am I supposed to specify criteria for a boolean function?

• Best way to store large dataset in SQL Server?

  - by gary

  I have a dataset which contains a string key field and up to 50 keywords associated with that information. Once the data has been inserted into the database there will be very few writes (INSERTS) but mostly queries for one or more keywords. I have read "Tagsystems: performance tests" which is MySQL based and it seems 2NF appears to be a good method for implementing this, however I was wondering if anyone had experience with doing this with SQL Server 2008 and very large datasets. I am likely to initially have 1 million key fields which could have up to 50 keywords each. Would a structure of keyfield, keyword1, keyword2, ... , keyword50 be the best solution or two tables keyid keyfield | 1 | | M keyid keyword Be a better idea if my queries are mostly going to be looking for results that have one or more keywords?

• MVC Client Validation from Service Layer

  - by GibboK

  I'm following this article http://www.asp.net/mvc/tutorials/older-versions/models-(data)/validating-with-a-service-layer-cs to include a Service Layer with Business Logic in my MVC Web Application. I'm able to pass messages from the Service Layer to the View Model in a Html.ValidationSummary using ModelState Class. I perform basic validation logic on the View Model (using DataAnnotation attributes) and I have ClientValidation enabled by default which displaying the error message on every single field of my form. The Business logic error message which come from the Service Layer are being displayed on Html.ValidationSummary only after Posting the form to the Server. After Validation from the Service Layer I would like highlight one or more fields and have the message from the Service Layer showing on these fields instead that the Html.ValidationSummary. Any idea how to do it? Thanks

• What is the best way to limit the amount of text that can be entered into a 'textarea'?

  - by Jesse Taber

  What is the best way to limit the amount of text that a user can enter into a 'textarea' field on a web page? The application in question is ASP .NET, but a platform agnostic answer is preferred. I understand that some amount of javascript is likely needed to get this done as I do not wish to actually perform the 'post' with that amount of data if possible as ASP .NET does have an upper limit to the size of the request that it will service (though I don't know what that is exactly). So maybe the real question is, what's the best way to do this in javascript that will meet the following criteria: -Must work equally well for both users simply typing data and copy/paste'ing data in from another source. -Must be as '508 compliance' friendly as possible.

• boost::Spirit Grammar for unsorted schema

  - by Hassan Syed

  I have a section of a schema for a model that I need to parse. Lets say it looks like the following. { type = "Standard"; hostname="x.y.z"; port="123"; } The properties are: The elements may appear unordered. All elements that are part of the schema must appear, and no other. All of the elements' synthesised attributes go into a struct. (optional) The schema might in the future depend on the type field -- i.e., different fields based on type -- however I am not concerned about this at the moment.

• Android MediaPlayer crashing app

  - by user1555863

  I have an android app with a button that plays a sound. the code for playing the sound: if (mp != null) { mp.release(); } mp = MediaPlayer.create(this, R.raw.match); mp.start(); mp is a field in the activity: public class Game extends Activity implements OnClickListener { /** Called when the activity is first created. */ //variables: MediaPlayer mp; //... The app runs ok, but after clicking the button about 200 times on the emulator, app crashed and gave me this error https://dl.dropbox.com/u/5488790/error.txt (couldn't figure how to post it here so it will appear decently) i am assuming this is because the MediaPlayer object is consuming up too much memory, but isn't mp.release() supposed to take care of this? What am i doing wrong here?

• Inserting Newline from XML to Database

  - by blackmage

  I am trying to parse this xml document in which a newline is required for certain fields and must be inserted into the database with the newline. But I've been running into problems. 1)First Problem: \n Character The first problem I had was using the \n like below. <javascript>jquery_ui.js\nshadowbox_modal.js\nuser_profile.js\ntablesorter.js</javascript> The problem was in the database the field came out ot be jquery_ui.js\nshadowbox_modal.js\n... and when output into html it was jquery_ui.jsnshadowbox_modal.jsn............... 2) Then I tried actually having newlines in the xml <javascript>jquery_ui.js shadowbox_modal.js user_profile.js tablesorter.js</javascript> The problem was the output become %20%20%20%20%20%20%20%20%20%20shadowbox_modal.js, and so forth. So how can I get a newline to hold from xml when entered into a database and then output with the newline still?

• More specific NSNumberFormatter failure behaviour

  - by Volte

  I have an NSTextField into which I need the user to enter a number between a max and min, and it would be nice if I could detect when the NSNumberFormatter fails that particular test so I can either display a nicer message ("The number is too large" is not very helpful, it needs to display the valid range) or simply set the field automatically to the nearest valid value. I've looked at the NSTextField delegate's -control:didFailToFormatString:errorDescription: method which doesn't seem to allow you to modify the error, and I've looked at overriding the NSNumberFormatter's -getObjectValue:forString:range:error: method which does give me an NSError that I can modify, but there doesn't seem to be any way to determine which specific error was returned. Since I am just entering a simple integer, I don't need most of the functionality in NSNumberFormatter, would I be better off just writing my own formatter from scratch?

• java serialization and final fields

  - by mdma

  I have an class defining an immutable value type that I now need to serialize. The immutability comes from the final fields which are set in the constructor. I've tried serializing, and it works (surprisingly?) - but I've no idea how. Here's an example of the class public class MyValueType implements Serializable { private final int value; private transient int derivedValue; public MyValueType(int value) { this.value = value; this.derivedValue = derivedValue(value); } // getters etc... } Given that the class doesn't have a no arg constructor, how can it be instantiated and the final field set? (An aside - I noticed this class particularly because IDEA wasn't generating a "no serialVersionUID" inspection warning for this class, yet successfully generated warnings for other classes that I've just made serializable.)

• Phantom updates due to decimal precision on calculated properties

  - by Jamie Ide

  This article describes my problem. I have several properties that are calculated. These are typed as decimal(9,2) in SQL Server and decimal in my C# classes. An example of the problem is: Object is loaded with a property value of 14.9 A calculation is performed and the property value is changed to 14.90393 When the session is flushed, NHibernate issues an update because the property is dirty Since the database field is decimal (9,2) the stored value doesn't change Basically a phantom update is issued every time this object is loaded. I don't want to truncate the calculations in my business objects because that tightly couples them to the database and I don't want to lose the precision in other calculations. I tried setting scale and precision or CustomType("Decimal(9,2)") in the mapping file but this appears to only affect schema generation. My only reasonable option appears to be creating an IUserType implementation to handle this. Is there a better solution?

• error 2016: Condition cannot be specified for Column member

  - by IP

  I am having some issues with Entity Framework in VS2010 The problem I'm getting is described very well here... http://social.msdn.microsoft.com/Forums/en/adonetefx/thread/cacf6a76-09a8-4c90-9502-d8b87c2f6bea It's basically happening when a Foreign key is pointed at the primary key of another table...but if I take off the StoreGeneratedPattern as "Identity", then it tries to insert a value into the identity field ** EDIT So, what it seems to be is that EF4 can't handle a null relationship when the primary key is set to StoreGeneratedPattern="Identity". If I create a FK pointing to this primary key, and make it nullable (effectively creating a 0...M relationship), then it throws this compilation error. Removing StoreGeneratedPattern="Identity" fixes the issue, but causes issues elseware It works if the foreign key is set to not nullable

• Providing localized error messages for non-attributed model validation in ASP.Net MVC 2?

  - by Lance McNearney

  I'm using the DataAnnotations attributes along with ASP.Net MVC 2 to provide model validation for my ViewModels: public class ExamplePersonViewModel { [Required(ErrorMessageResourceName = "Required", ErrorMessageResourceType = typeof(Resources.Validation))] [StringLength(128, ErrorMessageResourceName = "StringLength", ErrorMessageResourceType = typeof(Resources.Validation))] [DataType(DataType.Text)] public string Name { get; set; } [Required(ErrorMessageResourceName = "Required", ErrorMessageResourceType = typeof(Resources.Validation))] [DataType(DataType.Text)] public int Age { get; set; } } This seems to work as expected (although it's very verbose). The problem I have is that there are behind-the-scenes model validations being performed that are not tied to any specific attribute. An example of this in the above model is that the Age property needs to be an int. If you try to enter a non-integer value on the form, it will error with the following (non-localized) message: The field Age must be a number. How can these non-attribute validation messages be localized? Is there a full list of these messages available so I can make sure they are all localized?

• Does MS Test provide a default value equals comparison?

  - by fearofawhackplanet

  I want to test for example int orderId = myRepository.SubmitOrder(orderA); orderB = myRepository.GetOrder(orderId); Assert.AreEqual(orderA, orderB); // fail Obviously I need a value comparison here, but I don't want to have to provide an overridden Equals implementation for all of my classes purely for the sake of testing (it wouldn't be of any use in the rest of the app). Is there a provided generic method that just checks every field using reflection? Or if not, it is possible to write my own?

• How do I add a textbox to my other jQuery click function?

  - by marcamillion

  Right now, my script adds a box to the cursor when I click on an image, as can be seen in the following code. Please note, this is jQuery. $(function() { var tag_box = $("<div>").appendTo("body").css({"width":"40px", "height":"40px", "border":"4px solid #000000", "position":"absolute", "display":"none", "padding":"15px"}); $("#image-wrapper").live('click', function(e){ tag_box.css({"left": e.pageX - 40, "top": e.pageY - 40, "display":"block"}); }); I would like to add a text field to appear right below that tag_box on that same click. I tried to do this, but it hasn't worked out like I thought it would: var comment_box = $("<label> Comment: <input type='text' name='comment' autocomplete='off'></label>"); $("#image-wrapper").live('click', function(){ $("body").append(comment_box); }); Any assistance you can give me, would be greatly appreciated. Thanks.

• Does SQL Server Compact Edition (SqlCe) have a SNAPSHOT table like Oracle Lite?

  - by MusiGenesis

  In Oracle Lite, you can create a SNAPSHOT table which is like a normal table except that it tracks changes to itself. The syntax is CREATE SNAPSHOT TABLE tblWhatever ... and you can perform CRUD operations on it like a normal table. To get the change information, you query the table like this: SELECT * FROM tblWhatever + WHERE ... which returns all the rows in the table (including deleted ones) meeting the WHERE clause, and you can access each row's row_state column as a normal field (which is invisible to a normal SELECT * FROM tblWhatever WHERE ... query). Is there some way to do the same thing with Sql Compact Edition (3.5) - i.e. create a table that tracks changes without using RDA?

• javascript ajax variable question..

  - by Kelso

  Hey there, new to AJAX, JS.. Im trying to add to a Javascript/Ajax search script that I've put together. Previously, it had a single search field, called search_word, I added one called search_date. $(".search_button").click(function() { var search_word = $("#search_box").val(); var search_date = $("#datepicker").val(); var dataString = 'search_word='+ search_word; if(search_word=='') { } else { $.ajax({ type: "GET", url: "searchdata.php", data: dataString, In the Ajax, it appears to pass data of dataString, to my processing script. How do I add search date to the dataString so that I can use that var in my searchdata.php? In searchdata, I can do this $search_word=$_GET['search_word']; and use that var, but so far every time i attempt to alter the dataString, it breaks all the other functionality. Thanks!
