• Debugging asp.net with firefox and visual studio.net - very slow compared to IE

  - by john

  Debugging asp.net websites/web projects in visual studio.net 2005 with Firefox is loads slower than using IE. I've read something somewhere that there is a way of fixing this but i can't for the life of me find it again. Does anyone know what i'm on about and can point me in the right direction please? Cheers John edit sorry rob i haven't explained myself very well(again). I prefer Firefox for debugging (firebug etc) hitting F5 when debugging with IE the browser launches really quickly and clicking around my web application is almost instant and when a breakpont is hit i get to my code straight away with no delays. hitting F5 when debugging with FireFox the browser launches really slowly (ok i have plugins that slow FF loading) but clicking around my web application is really really slow and when a breakpoint is hit it takes ages to break into code. i swear i've read something somewhere that there is a setting in Firefox (about:config maybe?) that when changed to some magic setting sorts all this out.

• Type attribute for text_field

  - by Koning Baard XIV

  I have this code: <%= f.text_field :email, :type => "email", :placeholder => "[email protected]" %> So people can enter their email on an iPhone with the email keyboard instead of the ASCII keyboard. However, the output is: <input id="user_email" name="user[email]" placeholder="[email protected]" size="30" type="text" /> which should be: <input id="user_email" name="user[email]" placeholder="[email protected]" size="30" type="email" /> Is there a way to force Rails to use the email type instead of text, or must I use HTML directly? Thanks

• Looping over files - OpenCMS

  - by John Manak

  Hi! I'm developing a website using OpenCMS and am having a problem with creating links to files over which I loop using cms:contentload: <cms:contentload collector="allInFolder" param="faqs/|FaqFile" editable="false"> <b><a href="${opencms.filename}"><cms:contentshow element="Title" /></a></b><br /> </cms:contentload> This is a part of the index.jsp file. All the links unfortunately lead to index.jsp and not to the individual FAQ files. Do you know how to change this so that it works as expected? Thanks, John

• mysql first record retrieval

  - by Sammy

  While very easy to do in Perl or PHP, I cannot figure how to use mysql only to extract the first unique occurence of a record. For example, given the following table: Name Date Time Sale John 2010-09-12 10:22:22 500 Bill 2010-08-12 09:22:37 2000 John 2010-09-13 10:22:22 500 Sue 2010-09-01 09:07:21 1000 Bill 2010-07-25 11:23:23 2000 Sue 2010-06-24 13:23:45 1000 I would like to extract the first record for each individual in asc time order. After sorting the table is ascending time order, I need to extract the first unique record by name. So the output would be : Name Date Time Sale John 2010-09-12 10:22:22 500 Bill 2010-07-25 11:23:23 2000 Sue 2010-06-24 13:23:45 1000 Is this doable in an easy fashion with mySQL? Thanks, Sammy

• What is the best way to join/merge two tables by column cell matching in Excel?

  - by blunders

  I've found this excel add-in to buy that appears to do what I need, but I'd rather have code that's open to use as I wish. While a GUI is nice, it's not required. In an attempt to make the question more clear, I'm adding some two sample "input" tables in tab delimited form, and the resulting output table: SAMPLE_INPUT_TABLE_01 NAME<tab>Location John<tab>US Mike<tab>CN Tom<tab>CA Sue<tab>RU SAMPLE_INPUT_TABLE_02 NAME<tab>Age John<tab>18 Mike<tab>36 Tom<tab>54 Mary<tab>18 SAMPLE_OUTPUT_TABLE_02 NAME<tab>Age<Location> John<tab>18<tab>US Mike<tab>36<tab>CN Tom<tab>54<tab>CA Sue<tab>""<tab>RU Mary<tab>18<tab>"" If it matters, I'm using Office 2010 on Windows 7.

• Can MySQL Nested Select return list of results

  - by John

  Hi I want to write a mysql statement which will return a list of results from one table along with a comma separated list of field from another table. I think an example might better explain it Table 1 ======================== id First_Name Surname ---------------------- 1 Joe Bloggs 2 Mike Smith 3 Jane Doe Table 2 ======================== id Person_Id Job_id --------------------- 1 1 1 2 1 2 3 2 2 4 3 3 5 3 4 I want to return a list of people with a comma separated list of job_ids. So my result set would be id First_Name Surname job_id ------------------------------ 1 Joe Bloggs 1,2 2 Mike Smith 2 3 Jane Doe 3,4 I guess the sql would be something like select id, First_Name, Surname, (SELECT job_id FROM Table 2) as job_id from Table 1 but obviously this does not work so need to change the '(SELECT job_id FROM Table 2) as job_id' part. Hope this makes sense Thanks John

• Changing Render Kits in Browser

  - by John

  I'm working on a project to develop a cross-browser testing web app. Simply put, I'm tired of having to maintain multiple browsers on the same system and IE in VMware solely for the purpose of testing. Does anyone know if there is any way to change the render kit programmatically? For example, if I insert a URL, I would be able to load the URL and switch the browser render within a frame of some assortment. I am experienced with PHP, JS, and RoR if there is a solution using any of those. Thank you! John

• Get list of Unique many-to-many records from a queryset

  - by rsp

  My models: class Order(models.Model): ordered_by = models.ForeignKey(User) reasons = models.ManyToManyField(Reason) class Reason(models.Model): description = models.CharField() Basically a user creates an order and gives reasons for that order. ie, john has two orders (one for pencils because he is out AND because he doesn't like his current stock. a second order for pens because he is out). I want to print a list out of all reasons a user has placed his orders. So under john, it should print "he is out", "he doesn't like his current stock"; those two lines only. If I simply select all of john's orders, iterate through them and print out their "reasons" it'll print "he is out", "he doesn't like his current stock" and then "he is out" again. I don't want these duplicate values. How do I select a list of his reasons for ALL his orders so that the list has all unique rows?

• fetching a url using $.getJSON and parsing it correctly

  - by sofia

  This is probably really stupid but i can't find the problem with my code. It fetches a url that returns json and the function is then supposed to return a string: function getit() { var ws_url = 'example.com/test.js'; var user = false; $.getJSON(ws_url, function(data) { alert('user '+data.user);//shows john user = data.user || false; } ); return user;//should return john but returns false } test.js will have something like this: {"id":"12","username":"ses","user":"john","error":""} or like this: {"error":"123"} I also tried if(data.user){}else{} but it didn't work either.. So what am i missing? Thanks :)

• AjaxControlToolkit 3.0.30930.0 vs System.web.extension

  - by John

  Hi, I recently started to use AjaxControlToolkit v3.0.30930.0 in my application together with System.Web.Extension 3.5. My development environment is Visual Studio 2005, .NET Framework 2.0 and the development language is C#. The Ajax control I used is the ModalPopupExtender. I also used the UpdatePanel and updateprogress controls. Everything is working fine on my development machine. But I got a problem after I deployed the application to a server which does not have System.Web.Extension 3.5 installed, which is understandable. My question is, can the ajax controls I used work without System.Web.Extension 3.5? Say I revert the ajaxcontroltoolkit back to version 1.0.61025.0? I don't have the option to install .NET 3.5 as yet. Thank you for your help. John

• ASP.NET FileUpload

  - by John

  Greetings! I am using the ASP.NET FileUpload control to allow users to upload text files to our web server. Everything works great in terms of saving the file to where we wanted, etc, using the SaveAs() method of the control. But we were caught off guard by one seemingly simple caveat: the original timestamp of the uploaded file was lost such as the date last modified and date create. The date last modified and date created become the actual date and time when the file is saved to the server. My question is: is there anyway to retain the original timestamp by setting some attributes that I am not aware of yet or is it possible to read the metadata of the file to get its original time stamp? Any in-sight and suggestions are greatly appreciated. John

• Setting a Silverlight textbox control's width relatively

  - by John K.

  Hello, I tried searching on stackoverflow for an answer to my question but couldn't seem to find anything relevant. Since I'm relatively new to Silverlight, I'm not even sure if this is possible, but I am trying to figure out if it is possible to set a Silverlight textbox control's width value proportionally to it's immediate parent container? It would be nice to avoid hard coding a width value. Say you want to place a textbox control inside a horizontally aligned StackPanel control and have it's width always dynamically adjusted to be 80% of the total width of the StackPanel. Is this possible to do declaratively in your xaml markup, or will I need to resort to some codebehind attached to some event handler to accomplish this? fyi, I am currently using Visual Web Developer Express 2008 to write my silverlight code. thanks in advance, John

• Can I align the text in a C# balloon tip ?

  - by John

  Hello, I wrote a little C# program that displays text in a balloon tip from time to time. When the text is in English, there's no problem : Everything is aligned to the left and is readable, but sometimes I have some Hebrew text and a left alignment of a RTL language gets all screwy. I was wondering if there's a way to right-align the Hebrew text ? Google pointed me to articles that can help me change the balloon color and font, but none of them have an alignment argument. Is it even possible ? Any help will be appropriated. John

• Adding childs to list of parents with jquery /mvc2

  - by John Landheer

  Hi, I have a table of products on my page, each product has zero or more colors, the colors are shown as a list beneath the product. After the colors I have a button to add a color. The button will do an ajax call with the parent product id to a controller which will return a JSON object with color information. My problem is where to store the product id in the DOM, should I put it in a hidden field and use jquery in the click event of the "add color" to get to it? What is the best way to do this? TIA, John EDIT: The page is initially rendered on the server so I don't want to use jquery to add the id's to the page.
