• Multi-accordion help (CSS issue maybe?)

  - by Josh

  So, I've been trying to develop this multi-accordion news section for this site. It's actually all working, thanks to an insightful plugin. I've modified it a little bit so it works as I want it to, but I've run into two issues, one which is possibly CSS. Issue #1: The idea for the user is that when they view this page, they see all the recent headlines. They can also see who it has been posted by and how many comments have been made to this article. If they wish, they can then click on the headline and the field will expand into the article. They can then either make a comment or view the comments via clicking the View Comments link or clicking the "number of comments" link in the "Posted by..." area (a shortcut to the comments basically). The problem I'm having is if I make the AUTHOR or the "0" comments a link, it breaks the accordion because the accordion uses an A CLASS to open it up. I'm looking for a fix, I've tried making it a H1 or a DIV but that also breaks it. Issue #2: This is a pretty picky one, but when you click the headline it expands, but at least in Firefox (haven't tested it in Chrome yet) the text jumps from the right and to the left, locking in place from which the CSS tells it to (padding-left). I don't know why it's exactly doing that, if anyone has any insight on that, it'd be appreciated. A two-parter to this issue is when you open the Headline to the article and then decide to close the article by clicking on the Headline, parts of the accordion jumps from the darker purple to the light purple before the task is finished. I'm also interested fixing this, but this issue in its entirety are all pretty nit picky things. You can view the demo of the site here: http://www.notedls.com/demo Please if anyone has any advice or fixes, I'd appreciate it, I've been trying to get this all to work to the best of my ability, but I'm clearly no guru or expert. Thanks!

• Read data from ATOM file with jquery.

  - by carrerasrodrigo

  Hi, i'm trying to read a xml/atom file, the code is: $.ajax({ type: 'GET', url: options.url, data: options.data, dataType: 'xml', async:options.async, success: function(xml) { var feed = new JFeed(xml); if(jQuery.isFunction(options.success)) options.success(feed); } }); The atom file has a field like this: <entry> <content type="xhtml"> <div xmlns="http://www.w3.org/1999/xhtml">Docentes y alumnos desa...</div> </content> </entry> The code to read the content tag is: jQuery(this).find('content').eq(0).text(); this - the entry part. The problem is, when jQuery execute this line returns "Docentes y alumnos desa...". There is is a way that jQuery returns---- "<div xmlns="http://www.w3.org/1999/xhtml">Docentes y alumnos desa...</div>" Thanks!! and sorry for the english!!

• Rails - handling global site settings

  - by egarcia

  I'm developing a new rails application which is supposed to be installed several times in order to implement several sites. There are some things, like the "Site Title" or the "Default Number of Items per Page" that clearly belong to a "global settings" table / config file. I've made a list of the things I think I'll need: ActiveRecord model that is capable of: Storing different kinds of data. I suppose this would be accomplished encoding the values on a string on the db, probably with a "type" field. Indexing settings by name Validations based on a "type" attribute (i.e. don't accept invalid dates on "date" settings) Validations based on a allows_nil property. A controller that allows me to change settings via views. I'm pretty sure I could implement this myself, but I'm not willing to reinvent the wheel. I've done some searching, but I could only find rails-settings, which doesn't really serve me: I need a proper model & controller so I can use declarative-authorization, and it does not provide any controller or view facilities. Is there a gem or plugin out there that implements what I want, or any library I should look at? Thanks a lot.

• Generate an ID via COM interop

  - by Erik van Brakel

  At the moment, we've got an unmaintanable ball of code which offers an interface to a third party application. The third party application has a COM assembly which MUST be used to create new entries. This process involves two steps: generate a new object (basically an ID), and update that object with new field values. Because COM interop is so slow, we only use that to generate the ID (and related objects) in the database. The actual update is done using a regular SQL query. What I am trying to figure out if it's possible to use NHibernate to do some of the heavy lifting for us, without bypassing the COM assembly. Here's the code for saving something to the database as I envision it: using(var s = sessionFactory.OpenSession()) using(var t = s.BeginTransaction()) { MyEntity entity = new MyEntity(); s.Save(entity); t.Commit(); } Regular NH code I'd say. Now, this is where it gets tricky. I think I have to supply my own implementation of NHibernate.Id.IIdentifierGenerator which calls the COM assembly in the Generate method. That's not a problem. What IS a problem is that the COM assembly requires initialisation, which does take a bit of time. It also doesn't like multiple instances in the same process, for some reason. What I would like to know is if there's a way to properly access an external service in the generator code. I'm free to use any technique I want, so if it involves something like an IoC container that's no problem. The thing I am looking for is where exactly to hook-up my code so I can access the things I need in my generator, without having to resort to using singletons or other nasty stuff.

• win32 console - form example!

  - by Bach

  I'm trying to build a simple form in a c++ win32 console application. instead of using cin and keep prompting the user to enter the details, i would like to display the form labels then using the tab key, allow the user to tab through. What is the simplest way of doing this, without having to use ncurses? all I need is cout the below all at once: Name: Username: Email: set the cursor position next to name Field, then each time you hit tab, i gotoxy, and set the cursor at the next position, then set the the cin to the next variable eg. at startup gotoxy(nameX, nameY); cin >> name; Hit Tab/enter gotoxy(usernameX, usernameY); cin >> username; Hit Tab/enter gotoxy(emailX, emailY); cin >> email; is this even doable? I tried while loops with, GetAsyncKeyState, and keyboard events, but the cin is not working properly in that loop. is there any good example for a super simple form, or reference for doing that? I know how to SetConsoleCursorPosition, but how to implement the tabbing while still being able to capture cin? thanks

• Why does font-size only work when I set background-color on a button?

  - by Andrew Latham

  I am in Rails 3.2.6, on Chrome. I have the following code in my html.erb file: <div id="beta"> <%= form_tag({}, {:id => "id_search"}) do %> ID: <%= text_field_tag "beta_id" %> <%= submit_tag "Go" %> <% end %> </div> When I set the font-size to 24pt in my CSS file, the text field changes properly, but the button doesn't change at all. I pulled it up in my Developer Tools, and it was getting the CSS property, but just not changing its font size. Even when I put !important, nothing happened. I couldn't change the font-family either. JSFiddle: http://jsfiddle.net/R5CXg/ Changing other properties worked. When I changed the background-color property, the button suddenly turned square instead of round, and popped into the correct font-size and font-family. Why was this the case and how can I work around it?

• What are the best workarounds for known problems with Hibernate's schema validation of floating poin

  - by Jason Novak

  I have several Java classes with double fields that I am persisting via Hibernate. For example, I have @Entity public class Node ... private double value; When Hibernate's org.hibernate.dialect.Oracle10gDialect creates the DDL for the Node table, it maps the value field to a "double precision" type. create table MDB.Node (... value double precision not null, ... It would appear that in Oracle, "double precision" is an alias for "float". So, when I try to verify the database schema using the org.hibernate.cfg.AnnotationConfiguration.validateSchema() method, Oracle appears to describe the value column as a "float". This causes Hibernate to throw the following Exception org.hibernate.HibernateException: Wrong column type in DBO.ACL_RULE for column value. Found: float, expected: double precision A very similar problem is listed in Hibernate's JIRA database as HHH-1961 (http://opensource.atlassian.com/projects/hibernate/browse/HHH-1961). I'd like to avoid doing anything that will break MySql, Postgres, and Sql Server support so extending the Oracle10gDialect appears to be the most promising of the workarounds mentioned in HHH-1961. But extending a Dialect is something I've never done before and I'm afraid there may be some nasty gotchas. What is the best workaround for this problem that won't break our compatibility with MySql, Postgres, and Sql Server? Thanks for taking the time to look at this!

• How does an NSTextField know that it's value has changed?

  - by Brian Postow

  I have a textfield that can either be edited by hand, or set through another control. (It's a page number, so you can jump to page 16 by typing in 16, or you can page up and down with the next/prev buttons) I have the value of the text field bound to an int page variable. It seems to work correctly, when you type a page number in, it jumps, when you page up and down, the page number in the text box changes appropriately. However, at some level, when I page up and down, the text box doesn't seem to know that it's value has changed, because if I type 1 it doesn't do anything. It doesn't call the bound set-method or anything. It looks like the textfield is thinking "I'm already 1, so I don't need to do anything." Even though it was 5 because I hit next 4 times. If I type an number other than 1, it goes there. If I THEN type 1, it goes to page 1, because now it thinks it's on that other page. The problem seems to be that I'm changing the value of the textfield programatically, but some part isn't getting the message. Does this seem like a reasonable explanation? And either way, any ideas on what's causing it? thanks

• Non distinct Unique ID in MySQL database table.

  - by Geoff

  First of, a simplified version: I am wondering if I can create a trigger to activate during INSERT (it's actually LOAD DATA INFILE) and NOT enter records for an RMA already in my table? I have a table that has no records that are unique. Some may be duplicates but there is one field that I can use to know if the data has been entered or not. For instance RMA Op Days --------------------- 213 Repair 0.10 213 Test 0.20 213 Repair 0.10 So I could do an index on the three columns together but as you see it's possible for an RMA to be in a step for the same amount of time twice so it's possible to have duplicate records. This data comes from a report that I cannot edit and this is all it provides. The key is that an RMA's data is only in the report once so if my database already has that RMA in it's records I want to skip the loading of that RMA's records from the report. By all means please let me know if that didn't make sense, I'll Explain as needed. I'm sure it's not uncommon but I couldn't find anything on the net.

• How to sort objects in a many-to-many relationship in ruby on rails?

  - by Kenji Kina

  I've been trying to deal with this problem for a couple of hours now and haven't been able to come up with a clean solution. It seems I'm not too good with rails... Anyway, I have the following: In code: class Article < ActiveRecord::Base has_many :line_aspects, :dependent => :destroy has_many :aspects, :through => :line_aspects #plus a name field end class LineAspect < ActiveRecord::Base belongs_to :article belongs_to :aspect end class Aspect < ActiveRecord::Base belongs_to :data_type has_many :line_aspects has_many :articles, :through => :line_aspects end Now, what I would like to do, is to sort these in two steps. First list of Articles by their Articles.name, and then inside sort them by Aspect.name (note, not the middleman). For instance, alphabetically (sorry if the notation is not correct): [{ article => 'Apple', line_aspects => [ {:value => 'red'}, #corresponding to the Attribute with :name => 'color' {:value => 'small'} #corresponding to the Attribute with :name => 'shape' ] },{ article => 'Watermelon', line_aspects => [ {:value => 'green'}, #corresponding to the Attribute with :name => 'color' {:value => 'big'} #corresponding to the Attribute with :name => 'shape' ] }] Again, note that these are ordered by the aspect name (color before shape) instead of the specific values of each line (red before green). (NOTE: My intention is to displaye these in a table in the view) I have not found a good way to do this in rails yet (without resorting to N queries). Can anyone tell me a good way to do it?

• Where does IE store the ASP.NET_SessionId cookie?

  - by scherand

  I am a bit baffled here; using IE7, ASP.NET 2.0 and Cassini (the VS built-in web server; although the same thing seems to be true for "real" applications deployed in IIS) I am looking for the session-id-cookie. My test page shows a session id (by printing out Session.SessionId) and Response.Cookies.Keys contains ASP.NET_SessionId. So far so good. But I cannot find the cookie in IEs cookie-store! Nor does "remove all cookies" reset the session (as it does in FF)... So where - I am tempted to write that four letter word - does IE store that bloody cookie? Or am I missing something? By the way there is no hidden field with a session id either, as far as I can see. If I check in FF there is a cookie called ASP.NET_SessionId as I would expect. And as mentioned above deleting that cookie does start a new session; as I would expect. Can anybody imagine what is happening here?

• Jquery .val() for input only works once.

  - by Bolt_Head

  I'm trying to create a chat box for my game. The user type's their chat into the input:text feild and by ither pressing Enter or clicking the button submits the chat text. This all works, however for some reason after the first time a user submits a chat message it fails to get the text from the input field. Here is my code. $(document).ready(function() { $("#chatEnter").live('click',function(){ var chat = $('#chatText').val(); sendChat(chat); }); }); $(document).ready(function() { $("#chatText").keypress(function(e){ if ((e.which && e.which == 13) || (e.keyCode && e.keyCode == 13)) { var chat = $('#chatText').val(); sendChat(chat); return false; } else return true; }); }); function sendChat(chat) { alert(chat); //temp test alert $.getJSON("includes/boardUpdate.php",{chat: chat, bid: bid}); $('#chatText').val(""); } It doesn't matter if i first submit a text by clicking the button or pressing enter, all future attempts submit blank entrys until I refresh the page. Edit: I've tried it with and without the line to clear the text box, same results both ways. Your help is appreciated.

• Really simple JSON serialization in .NET

  - by Evgeny

  I have some simple .NET objects I'd like to serialize to JSON and back again. The set of objects to be serialized is quite small and I control the implementation, so I don't need a generic solution that will work for everything. Since my assembly will be distributed as a library I'd really like to avoid a dependency on some third-party DLL: I just want to give users one assembly that they can reference. I've read the other questions I could find on converting to and from JSON in .NET. The recommended solution of JSON.NET does work, of course, but it requires distributing an extra DLL. I don't need any of the fancy features of JSON.NET. I just need to handle a simple object (or even dictionary) that contains strings, integers, DateTimes and arrays of strings and bytes. On deserializing I'm happy to get back a dictionary - it doesn't need to create the object again. Is there some really simple code out there that I could compile into my assembly to do this simple job? I've also tried System.Web.Script.Serialization.JavaScriptSerializer, but where it falls down is the byte array: I want to base64-encode it and even registering a converter doesn't let me easily accomplish that due to the way that API works (it doesn't pass in the name of the field).

• VBA compare and sort strings with quirky characters

  - by Smandoli

  I am comparing text values from two DAO recordsets in MS Access. I sort on the text field, then go through both recordsets comparing the values from each. The sets are substantially different and while they're mostly alpha-numeric, spaces and symbols like hyphens and periods are very common. My program depends on predictable sorting and fool-proof comparing. But unfortunately, the sort will rank two values differently than the comparison function. StrComp is the obvious first choice: varResult = StrComp(Val_1, Val_2) RFA-300 14.9044 RFA300 14-2044 But for the two pairs above, StrComp returns a different value than one would expect based on the sort. Including vbTextCompare or vbBinaryCompare affects StrComp's result, but not so as to solve the problem. Note the values must always be compared as strings. Of course I make sure that "14-2044" and "14.9044" aren't evaluated as -2030 and ~15. That's not the cause of my problem. I learned API-based functions are more reliable for quirky texts, so I tried these: varResult = CompareString(LOCALE_SYSTEM_DEFAULT, _ SORT_STRINGSORT, strVal_2, -1, strVal_1, -1) varResult = CompareString(LOCALE_SYSTEM_DEFAULT, _ NORM_IGNOREWIDTH, strVal_2, -1, strVal_1, -1) The first one returns the opposite of StrComp. The second one returns the same as StrComp. But neither yields a result that is consistent with the sort order. (NORM_IGNOREWIDTH is probably not relevant, but I needed a place-holder substitute and it looked as good as any.) UPDATE: This is a complete rewrite of the original post, deleting all the info about why I really need this -- just take my word for it and enjoy the brevity.

• A couple of questions about NHibernate's GuidCombGenerator

  - by Eyvind

  The following code can be found in the NHibernate.Id.GuidCombGenerator class. The algorithm creates sequential (comb) guids based on combining a "random" guid with a DateTime. I have a couple of questions related to the lines that I have marked with *1) and *2) below: private Guid GenerateComb() { byte[] guidArray = Guid.NewGuid().ToByteArray(); // *1) DateTime baseDate = new DateTime(1900, 1, 1); DateTime now = DateTime.Now; // Get the days and milliseconds which will be used to build the byte string TimeSpan days = new TimeSpan(now.Ticks - baseDate.Ticks); TimeSpan msecs = now.TimeOfDay; // *2) // Convert to a byte array // Note that SQL Server is accurate to 1/300th of a millisecond so we divide by 3.333333 byte[] daysArray = BitConverter.GetBytes(days.Days); byte[] msecsArray = BitConverter.GetBytes((long) (msecs.TotalMilliseconds / 3.333333)); // Reverse the bytes to match SQL Servers ordering Array.Reverse(daysArray); Array.Reverse(msecsArray); // Copy the bytes into the guid Array.Copy(daysArray, daysArray.Length - 2, guidArray, guidArray.Length - 6, 2); Array.Copy(msecsArray, msecsArray.Length - 4, guidArray, guidArray.Length - 4, 4); return new Guid(guidArray); } First of all, for *1), wouldn't it be better to have a more recent date as the baseDate, e.g. 2000-01-01, so as to make room for more values in the future? Regarding *2), why would we care about the accuracy for DateTimes in SQL Server, when we only are interested in the bytes of the datetime anyway, and never intend to store the value in an SQL Server datetime field? Wouldn't it be better to use all the accuracy available from DateTime.Now?

• Adding Css class to all <input type'text'> elements? Javascript / Css?

  - by Kohan

  I want to apply a CSS class to every textbox in my site: <div class="editor-label"> <label for="FoodType">FoodType</label> </div> <div class="editor-field"> <input id="HelpText" name="FoodType" type="text" value="" /> </div> <p> <input type="submit" value="Create" /> </p> And I thought, Hey! Easy. I'll add a jquery function to find them all in the masterpage. <script type="text/javascript"> $(document).ready(function(){ $('input').addClass('textbox'); } </script> Unfortunately this will also select the submit button. How can i only select input elements that have a text type attribute? Alternativly is this possible using entirely CSS? If both these methods are not possible, i guess i will just have to manually add the class to every textbox i make? Cheers, Kohan.

• A Digg-like rotating homepage of popular content, how to include date as a factor?

  - by Ferdy

  I am building an advanced image sharing web application. As you may expect, users can upload images and others can comments on it, vote on it, and favorite it. These events will determine the popularity of the image, which I capture in a "karma" field. Now I want to create a Digg-like homepage system, showing the most popular images. It's easy, since I already have the weighted Karma score. I just sort on that descendingly to show the 20 most valued images. The part that is missing is time. I do not want extremely popular images to always be on the homepage. I guess an easy solution is to restrict the result set to the last 24 hours. However, I'm also thinking that in order to keep the image rotation occur throughout the day, time can be some kind of variable where its offset has an influence on the image's sorting. Specific questions: Would you recommend the easy scenario (just sort for best images within 24 hours) or the more sophisticated one (use datetime offset as part of the sorting)? If you advise the latter, any help on the mathematical solution to this? Would it be best to run a scheduled service to mark images for the homepage, or would you advise a direct query (I'm using MySQL) As an extra note, the homepage should support paging and on a quiet day should include entries of days before in order to make sure it is always "filled" I'm not asking the community to build this algorithm, just looking for some advise :)

• Subqueries on Java GAE Datastore

  - by Dmitry

  I am trying to create a database of users with connection between users (friends list). There are 2 main tables: UserEntity (main field id) and FriendEntity with fields: - initiatorId - id of user who initiated the friendship - friendId - id of user who has been invited. Now I am trying to fetch all friends of one particular user and encountered some problems with using subqueries in JDO here. Logically the query should be something like this: SQL: SELECT * FROM UserEntity WHERE EXISTS (SELECT * FORM FriendEntity WHERE (initiatorId == UserEntity.id && friendId == userId) || (friendId == UserEntity.id && initiatorId == userId)) or SELECT * FROM UserEntity WHERE userId IN (SELECT * FROM FriendEntity WHERE initiatorId == UserEntity.id) OR userId IN (SELECT * FROM FriendEntity WHERE friendId == UserEntity.id) So to replicate the last query in JDOQL, I tried to do the following: Query friendQuery = pm.newQuery(FriendEntity.class); friendQuery.setFilter("initiatorId == uidParam"); friendQuery.setResult("friendId"); Query initiatorQuery = pm.newQuery(FriendEntity.class); initiatorQuery.setFilter("friendId == uidParam"); initiatorQuery.setResult("initiatorId"); Query query = pm.newQuery(UserEntity.class); query.setFilter("initiatorQuery.contains(id) || friendQuery.contains(id)"); query.addSubquery(initiatorQuery, "List initiatorQuery", null, "String uidParam"); query.addSubquery(friendQuery, "List friendQuery", null, "String uidParam"); query.declareParameters("String uidParam"); List<UserEntity> friends = (List<UserEntity>) query.execute(userId); In result I get the following error: Unsupported method while parsing expression. Could anyone help with this query please?

  Hi i am using jQuery validate for my form validation. The form is inside tabs.When i get an error i add an icon to the tab that error exist to be visual by the user So far so good. My problem is that after correct the error i can not remove the error in tab icon. I was assuming that validator is accessible via success but its not Assuming that the first tab (tab0) has 3 field for validation (field1,field2,field3) Here is the full code $("form#Form1") .validate({ invalidHandler: function(form, validator) { //TAB 0 if (validator.errorMap.field1 != "" && validator.errorMap.field2 != "" && validator.errorMap.field3 != "") { if ($("#tabs>ul>li").eq(0).find("img").length == 0) { $("#tabs>ul>li").eq(0).prepend("<img src=\"error.gif\">"); } } }, errorClass: "errorField", errorElement: "p", errorPlacement: function(error, element) { var parent = element.parent(); parent.addClass("error"); error.prependTo( parent ); }, //validator in not accessible via success //so my code its not working success: function(element,validator) { var parent = element.parent(); parent.removeClass("error"); $(parent).children("p.errorField").remove(); //TAB 0 if (validator.errorMap.field1 == "" && validator.errorMap.field2 == "" && validator.errorMap.field2 == "") { if ($("#tabs>ul>li").eq(0).find("img").length == 0) { $("#tabs>ul>li").eq(0).find("img").remove(); } } }, rules: { field1: { required: true }, field2: { required: true }, field3: { required: true } } }); Any suggestion is welcome.

• Quitting an application - is that frowned upon?

  - by Ted

  Moving on in my attempt to learn Android I just read the following: Question: Does the user have a choice to kill the application unless we put a menu option in to kill it? If no such option exists, how does the user terminate the application? Answert (Romain Guy): The user doesn't, the system handles this automatically. That's what the activity lifecycle (especially onPause/onStop/onDestroy) is for. No matter what you do, do not put a "quit" or "exit" application button. It is useless with Android's application model. This is also contrary to how core applications work. Hehe, for every step I take in the Android world I run into some sort of problem =( Apparently, you cannot quit an application in Android (but Android can very well totally destroy your app whenever it feels like it). Whats up with that? I am starting to think that its impossible to write an app that functions as a "normal app" - that the user can quit the app when he/she decides to do so. That is not something that should be relied upon the OS to do. The application I am trying to create is not an application for the Android Market. It is not an application for "wide use" by the general public, it is a business app that is going to be used in a very narrow business field. I was actually really looking forward to developing for the Android-platform, since it addresses a lot of issues that exist in Windows Mobile and .NET. However, the last week has been somewhat of a turnoff for me... I hope I dont have to abandon Android, but it doesnt look very good right now =( Is there a way for me to really quit the application?

• N-tier architecture and unit tests (using Java)

  - by Alexandre FILLATRE

  Hi there, I'd like to have your expert explanations about an architectural question. Imagine a Spring MVC webapp, with validation API (JSR 303). So for a request, I have a controller that handles the request, then passes it to the service layer, which passes to the DAO one. Here's my question. At which layer should the validation occur, and how ? My though is that the controller has to handle basic validation (are mandatory fields empty ? Is the field length ok ? etc.). Then the service layer can do some tricker stuff, that involve other objets. The DAO does no validation at all. BUT, if I want to implement some unit testing (i.e. test layers below service, not the controllers), I'll end up with unexpected behavior because some validations should have been done in the Controller layer. As we don't use it for unit testing, there is a problem. What is the best way to deal with this ? I know there is no universal answer, but your personal experience is very welcomed. Thanks a lot. Regards.

• Why does a non-dynamically created iframe shim show, but a dynamically created one does not?

  - by Carter

  I have a custom control that is made up of a text field and the ajax control toolkit dateextender. In IE6 I'm hitting the z-index bug where the calendar is showing behind select boxes. If I have the shim sitting in the control, initially hidden, it seems to display fine when the calendar is shown, but when I try to dynamically create the shim on showing it doesn't appear. I've tried bgiframe and some examples I found on SO, no luck. Here is my javascript code currently... var dateEditorShim; function dateEditor_OnShown(dateControl, emptyEventArgs) { var shimWidth = dateControl._width; var shimHeight = dateControl._height; //var dateEditorShim; //dateEditorShim = document.getElementById(dateEditorShimId); dateEditorShim = document.createElement('iframe'); dateEditorShim.setAttribute('src', 'javascript:"";'); dateEditorShim.setAttribute('frameBorder', '0'); dateEditorShim.style.width = dateControl._popupDiv.offsetWidth; dateEditorShim.style.height = dateControl._popupDiv.offsetHeight; dateEditorShim.style.top = dateControl._popupDiv.style.top; dateEditorShim.style.left = dateControl._popupDiv.style.left; dateControl._popupDiv.style.zIndex = 999; dateEditorShim.style.zIndex = 998; dateEditorShim.style.display = "block"; } function dateEditor_OnHiding(dateControl, emptyEventArgs) { var shimWidth = 0; var shimHeight = 0; //var dateEditorShim; //dateEditorShim = document.getElementById(dateEditorShimId); dateEditorShim.style.width = 0; dateEditorShim.style.height = 0; dateEditorShim.style.top = 0; dateEditorShim.style.left = 0; dateEditorShim.style.display = "none"; } You'll notice I have a commented out bit of code that gets an iframe that is embedded into the page, as I said, in this case the iframe at least shows up, but when I dynamically create it like the code above currently, it doesn't. I'm trying to figure out why. Any ideas?
