• Add a Carriage Return to the Output of an XSL Transformation

  - by dsrekab

  I am trying to use XSLT to convert an XML document to a text file and the text of the document looks fine. However, I need to add a carriage return after the end of each line (NOT A CRLF) and I seem to be failing in every attempt. I have tried adding just a CR at the end of the line like this: <xsl:text>&#xD;</xsl:text> I have tried changing my media-type to string, I have tried to add the disable-output-escaping attribute to the text element, but it always adds a CRLF. This is on a Windows OS and I know that Windows uses CRLF for a new line, but I would have thought you could override that if you said to specifically use only the CR or the LF (e.g. VB.net's VBCR or VBLF). Does anyone know if it is possible to only output a CR with XSLT? Thanks in advance.

• WCFExtras SOAP headers support returns null reference exception

  - by jlp

  I use WCFExtras to add headers to my service. I set up everything according to http://wcfextras.codeplex.com/wikipage?title=HowToUse&referringTitle=Home My WCF client works but throws NullReferenceException on both: client.InnerChannel.SetHeader("myHeader", new local.Header()); and var header = client.InnerChannel.GetHeader<local.Header>("myHeader"); I wonder if web.config element <wsdlExtensions location="noidea" singleFile="True"/> might cause a problem because I don't know what type in location attribute. I simply tried to type service address but it didn't fix anything.

• jquery atrr("href") is not consistent ..in sharepoint

  - by alienavatar

  Hi all I have a jquery function(This is not written by me anyway still I am learning). In that we are replacing urls using f.attr("href") in several places. I am not understanding that from where this href value will be binded. And why the value(f.attr("href")) is changing place to place. I mean to say it is having some value @ one location and if I give the same it is giving me different value at other location. I read in article that The .attr() method gets the attribute value for only the first element in the matched set..What is the matched set means

• problem with parsing string from excel file

  - by ohana

  hi, i have ruby code to parse data in excel file using Parseexcel gem. I need to save 2 columns in that file into a Hash, here is my code: worksheet.each { |row| if row != nil key = row.at(1).to_s.strip value = row.at(0).to_s.strip if !parts.has_key?(key) and key.length 0 parts[key] = value end end } however it still save duplicate keys into the hash: "020098-10". I checked the excel file at the specified row and found the difference are " 020098-10" and "020098-10". the first one has a leading space while the second doesn't. I dont' understand is it true that .strip function already remove all leading and trailing white space? also when i tried to print out key.length, it gave me these weird number: 020098-10 length 18 020098-10 length 17 which should be 9....

• WPF - copy/paste selection with custom font family

  - by summergoat

  I have a custom font family embedded in my WPF application which I can reference by specifying a base URI and font family name. new FontFamily(new Uri("pack://application:,,,/Fonts/"), "./#My Custom Font Family"); However, when I copy a selection which uses this font the xaml on the clipboard resembles the following <Run Text="Foo" FontFamily="./#My Custom Font Family" /> When I paste into the same RichTextBox I lose the font as it falls back to the system default because - When a FontFamily is specified as an attribute in markup, the base URI value is always implied—its value is the URI of the XAML page. http://msdn.microsoft.com/en-us/library/system.windows.media.fontfamily.aspx and my xaml page is not located in the same directory as the custom font family. Any ideas for a workaround?

• Is there an easier way to typecast with unknown types?

  - by Adam S

  Hi all. I am writing a function to recurse my XAML and add all the controls to a hashtable, with their names being the keys. Unfortunately it seems like I have to go through and list every possible type: void Recurse_Controls(object start) { string start_type = start.GetType().ToString(); if (start_type == "StackPanel") { ControlsByName.Add(((StackPanel)start).Name, start); foreach (object item in ((StackPanel)start).Children) { Recurse_Controls(item); } } if (start_type == "Grid") { ControlsByName.Add(((Grid)start).Name, start); foreach (object item in ((Grid)start).Children) { Recurse_Controls(item); } } } Is there a simpler way of doing this?

• Using Regex to modify a String

  - by Christine Dehner

  I have a String that looks like this: Blah blah one.<tmp>[[url=b, link=c]]</tmp> Blah blah two. Also remember, blah blah three.<tmp>[[url=d, link=e]]</tmp> So I want to get b and d (the url attribute of tmp), and change the String so that it looks like this (the ex() function returns a String): Blah blah one.<tmp>[[url=b, link=c, add=ex(b)]]</tmp> Blah blah two. Also remember, blah blah three.<tmp>[[url=d, link=e, add=ex(d)]]</tmp> I need to use regex because no existing library parses this type of markup. I hope my explanation is clear. Thanks in advance!

• Sorting of table column by string length not working as intended when done in IB via cocoa - binding

  - by Miraaj

  Hi all, I made a sample application displaying list of employees with their salaries over NSTableView using NSArrayController. Basic functionality is working as intended. Also sorting is working fine when Selector - compare or caseInsensitiveCompare is assigned in attribute pane for table column- employeeName. Problem occurs when I try to sort it by string length by setting selector in IB as - length, for the table column - employeeName. It does sorting by string length but does it inappropriately. It is doing sorting on alternate clicks ie. on first click it sorts the content in table in descending order by length. Then on second click it does not arrange contents in ascending order by length but sets arrow on top as in ascending. Then on third click it arranges contents in ascending order by length but sets arrow on top of table column as in descending and so on... Can anyone suggest if I am wrong somewhere? Thanks, Miraaj

• sql query question / count

  - by scheibenkleister

  Hi, I have houses that belongs to streets. A user can buy several houses. How do I find out, if the user owns an entire street? street table with columns (id/name) house table with columns (id/street_id [foreign key] owner table with columns (id/house_id/user_id) [join table with foreign keys] So far, I'm using count which returns the result: select count(*), street_id from owner left join house on owner.house_id = house.id group by street_id where user_id = 1 count(*) | street_id 3 | 1 2 | 2 A more general count: select count(*) from house group by street_id returns: count(*) | street_id 3 | 1 3 | 2 How can I find out, that user 1 owns the entire street 1 but not street 2?

• How can I make an expect script prompt for a password?

  - by MiniQuark

  I have an expect script that connects to a few routers through ssh. All these routers have the same password (I know, it's wrong), and the script needs to know that password in order to be able to connect to the routers. Currently, the password is passed to my script as an argument on the command line, but this means that there's a trace of that password in my .bash_history file as well as in the running processes. So instead I would like the user to be prompted for a password, if possible silently. Do you know whether or not it's possible to prompt the user for a password with expect? Thank you. Edit: if I was connecting to servers instead of routers, I would probably use ssh keys instead of passwords. But the routers I'm using just support passwords.

• Rails - default value in text_field but only for new_record?

  - by jyoseph

  On a Content model have an attribute named slug. When creating a new record, I want to use a helper to populate this field, but on an existing record I want to use the value from the database. Currently I have: <%- if @content.new_record? -%> <%= f.text_field :slug, :value => "#{generate_slug(6)}" %> <%- else %> <%= f.text_field :slug %> <%- end %> But that seems a bit verbose. Is this the best way, or is there no other way? (Rails newb just trying to find the "Rails way" on issues I'm unsure of) Edit I should note that the helper is currently in /app/helpers/application_helper.rb

• Django json serialization problem

  - by codingJoe

  I am having difficulty serializing a django object. The problem is that there are foreign keys. I want the serialization to have data from the referenced object, not just the index. For example, I would like the sponsor data field to say "sponsor.last_name, sponsor.first_name" rather than "13". How can I fix my serialization? json data: {"totalCount":"2","activities":[{"pk": 1, "model": "app.activity", "fields": {"activity_date": "2010-12-20", "description": "my activity", "sponsor": 13, "location": 1, .... model code: class Activity(models.Model): activity_date = models.DateField() description = models.CharField(max_length=200) sponsor = models.ForeignKey(Sponsor) location = models.ForeignKey(Location) class Sponsor(models.Model): last_name = models.CharField(max_length=20) first_name= models.CharField(max_length=20) specialty = models.CharField(max_length=100) class Location(models.Model): location_num = models.IntegerField(primary_key=True) location_name = models.CharField(max_length=100) def activityJSON(request): activities = Activity.objects.all() total = activities.count() activities_json = serializers.serialize("json", activities) data = "{\"totalCount\":\"%s\",\"activities\":%s}" % (total, activities_json) return HttpResponse(data, mimetype="application/json")

• Question regarding checking the state of a checkbox class

  - by Joseph

  I'll try and make this question simple. Can I assign a class to a series of different checkboxes, and use Jquery to do something when any one of those checkboxes is checked? Searching around on the internet I have found documentation on grabbing the name: $('input[name=foo]').is(':checked') but when I swap out the name attribute for the class attr, it won't work! How can I set an event to occur if any of the checkboxes with this certain class is checked? Please help me out! Thanks

• ^+Left Arrow and ^+Right Arrow suddenly stopped working on OS X

  - by user293261

  Hello. I'm not really sure what to make of this. The key combination of ^← and ^→ have stopped working for one of the two users on my OS X installation. I use these keys all the time (switching tabs in terminal, IntelliJ primarily), and it's driving me crazy. On one user account, it works fine. On the other, it doesn't. This happened today and nothing significant comes to mind that would have caused some weird keybinding issue. If anyone has heard of or experienced anything like this, I would very much appreciate your advice! Thanks.

• Workaround for abstract attributes in Java

  - by deamon

  In Scala I would write an abstract class with an abstract attribute path: abstract class Base { val path: String } class Sub extends Base { override val path = "/demo/" } Java doesn't know abstract attributes and I wonder what would be the best way to work around this limitation. My ideas: a) constructor parameter abstract class Base { protected String path; protected Base(String path) { this.path = path; } } class Sub extends Base { public Sub() { super("/demo/"); } } b) abstract method abstract class Base { // could be an interface too abstract String getPath(); } class Sub extends Base { public String getPath() { return "/demo/"; } } Which one do you like better? Other ideas? I tend to use the constructor since the path value should not be computed at runtime.

• Clone DB table row through MVC in MSSQL

  - by sslepian

  Is there a simple solution for duplicating table rows in MSSQL as well as all table rows with foreign keys pointing to the cloned table row? I've got a "master" table and a bunch of "child" tables which have a foreign key into the ID of the master table. I need to not only create a perfect copy of the master table, but clone each and every child table referencing the master table. Is there a simpler way to do this than creating a new row in the master table, copying in the information from the row to be cloned, then going through each child table and doing the same with each row pointing to the cloned row in the master table? I'm using a MSSQL 2005 Database accessed through C# ASP.net MVC 1.0.

• What is the most efficient way to store a mapping "key -> event stream"?

  - by jkff

  Suppose there are ~10,000's of keys, where each key corresponds to a stream of events. I'd like to support the following operations: push(key, timestamp, event) - pushes event to the event queue for key, marked with the given timestamp. It is guaranteed that event timestamps for a particular key are pushed in sorted or almost sorted order. tail(key, timestamp) - get all events for key since the given timestamp. Usually the timestamp requests for a given key are almost monotonically increasing, almost synchronously with pushes for the same key. This stuff has to be persistent (although it is not absolutely necessary to persist pushes immediately and to keep tails with pushes strictly in sync), so I'm going to use some kind of database. What is the optimal kind of database structure for this task? Would it be better to use a relational database, a key-value storage, or something else?

• How do I start a XUL Runner application maximized?

  - by Anthony D

  I've started developing my first app with XUL and I've run into a problem that I can't seem to solve. All I want to do is have my app start maximized. I've set the sizemode attribute to maximized on my top level window element but that has no effect. My prefs.js file has the following line: pref("toolkit.defaultChromeFeatures", "chrome,centerscreen,menubar,resizable,status,toolbar,scrollbars"); This also does not work. My window appears and it only has a close button (X) and does not have a minimize or maximize button. Any ideas???
