• Extending ClaimsIdentity in MVC3

  - by Steoates

  I've got my claims set-up with MVC3 using azure and everything is going well. What I need to do now is extend the Claims Identity that's in the current thread / http context and add my own information (DOB, Address.. that sort of stuff) so my question is - where is the best place to do this? any examples would be great.. I presume that when the user is authenticated id then have to go to the DB and pull back the relevant record for the user then add it to the custom Claims Identity object? cheers. ste.

• Echoing a pseudo column value after a COUNT

  - by rob - not a robber

  Hi Gang... Please don't beat me if this is elementary. I searched and found disjointed stuff relating to pseudo columns. Nothing spot on about what I need. Anyway... I have a table with some rows. Each record has a unique ID, an ID that relates to another entity and finally a comment that relates to that last entity. So, I want to COUNT these rows to basically find what entity has the most comments. Instead of me explaining the query, I'll print it SELECT entity_id, COUNT(*) AS amount FROM comments GROUP BY entity_id ORDER BY amount DESC The query does just what I want, but I want to echo the values from that pseudo column, 'amount' Can it be done, or should I use another method like mysql_num_rows? Thank you!!!

• Auto-generated values for columns in database

  - by Jamal

  Is it a good practice to initialize columns that we can know their values in database, for example identity columns of type unique identifier can have a default value (NEWID()), or columns that shows the record create date can have a default value (GETDATE()). Should I go through all my tables and do this whereever I am sure that I won't need to assign the value manually and the Auto-generated value is correct. I am also thinking about using linq-to-sql classes and setting the "Auto Generated Value" property of these columns to true. Maybe this is what everybody already knows or maybe I am asking a question about a fundamental issue, if so please tell me.

• Re-measuring custom item renderer on a List

  - by leolobato

  I'm writing an Adobe Air client to a service similar to Twitter. On the timeline (List component) I have a custom item renderer which is basically a Canvas with a fixed-width Image and a Text control, which is multi-line. If the text is long enough to change the Canvas height, it will only be resized if I manually change the width of the Window, forcing a redraw of all renderers. If I simply scroll through the List, all "new" renderers will have the minimum height possible (which is the Image height). Any ideas on how to force the re-measurement of the renderer when I set it's data? Thanks in advance! :)

• Python: Find X to Y in a list of strings.

  - by TheLizardKing

  I have a list of maybe a 100 or so elements that is actually an email with each line as an element. The list is slightly variable because lines that have a \n in them are put in a separate element so I can't simply slice using fixed values. I essentially need a variable start and stop phrase (needs to be a partial search as well because one of my start phrases might actually be Total Cost: $13.43 so I would just use Total Cost:.) Same thing with the end phrase. I also do not wish to include the start/stop phrases in the returned list. In summary: email = ['apples','bananas','cats','dogs','elephants','fish','gee'] start = 'ban' stop = 'ele' the magic here new_email = ['cats','dogs'] NOTES While not perfect formatting of the email, it is fairly consistent so there is a slim chance a start/stop phrase will occur more than once. There are also no blank elements.

• SQL to get range of results in alphabetical order

  - by Tom Gullen

  I have a table, tblTags which works in much the same way as StackOverflows tagging system. When I view a tags page, let's say the tag Tutorial I want to display the 10 tags before and after it in alphabetical order. So if we are given the tag Tutorial of ID 30 how can we return a record set in the order resembling: Tap Tart > Tutorial Umbrellas Unicorns Xylaphones I have thought of ways of doing this, badly, in my opinion as they involve retrieving ugly amounts of data. I'm not sure if it's possible to do something along the lines of (pseudo): SELECT RANGE(0 - 30) FROM tblTags ORDER BY Name ASC But how do you know the position of the tutorial tag in the list in an efficient manner without traversing the entire list until you find it? I'm using SQL Server 2008 R2 Express with LINQ if it makes any difference, SQL queries or LINQ would be great answers, thanks!

• How to append to an XML response an error attribute using Ruby on Rails 3?

  - by user502052

  I am trying to implement REST APIs, so in my RoR3 application I have XML responses. Before to pass to a consumer the XML, I wuold like to check if there are errors and, if so, send back a response with error messages. I read "Active Record Validations and Callbacks" guides on the RoR website, but it seems not work in my case. I extract from the database a resource doing @response = User.find_by_id(1) and I wuold like, if possible, to add error to it. Seeing some examples I have seen how to report errors in an XML file format.xml { render :xml => @response.errors } but how I can add append new errors to the @response? Maybe something like this: errors.add(:password, "is invalid")

• Query for model by key

  - by Jason Hall

  What I'm trying to do is query the datastore for a model where the key is not the key of an object I already have. Here's some code: class User(db.Model): partner = db.SelfReferenceProperty() def text_message(self, msg): user = User.get_or_insert(msg.sender) if not user.partner: # user doesn't have a partner, find them one # BUG: this line returns 'user' himself... :( other = db.Query(User).filter('partner =', None).get() if other: # connect users else: # no one to connect to! The idea is to find another User who doesn't have a partner, that isn't the User we already know. I've tried filter('key !=, user.key()), filter('__key__ !=, user.key()) and a couple others, and nothing returns another User who doesn't have a partner. filter('foo !=, user.key()) also returns nothing, for the record.

• Access VBA remove CR & LF only from the beginning of a text string by searching for them

  - by uZI

  Hi there I need to remove line breaks from the beginning of a memo type records. I dont want to use the replace function as it would remove all line breaks from the record which is not desired. Its only the line breaks at the beginning of the field that I am interested in removing. Furthermore, the my records do not always begin with a line break so I cant really use text positioning, the solution would be to look for line break at the beginning instead of always expecting it at the beginning. click here for a sample of what my data looks like any help will be greatly appreciated

• Automated Testing tools for HTML5 Canvas

  - by user432195

  I'm looking for a tool to do some automated GUI testing on a HTML5 canvas component we're developing. Basically I'm looking for a tool that is able to record the clicks and events on the canvas component and is able to replay those events. So far most of the testing tools like Telerik WebUI Testing Suite, Selenium, TestSwarm, qUnit, Jasmine, Hudson seems that they don't fully support HTML5 canvas testing. Would you guys know a testing tool that already supports that ? If not, would you know how companies are doing automated testing of HTML5 canvas ? Thanks, Andy N.

• Android - LinearLayout Horizontal with wrapping children

  - by kape123

  Is there a property to set for Android's LinearLayout that will enable it to properly wrap child controls? Meaning - I have changeable number of children and would like to lay out them horizontally like: Example: Control1, Control2, Control3, ... I do that by setting: ll.setOrientation(LinearLayout.HORIZONTAL); foreach (Child c in children) ll.addView(c); However, if I have large number of children, last one gets cuts off, instead of going to next line. Any idea how this can be fixed?

• Recording audio from many source/microphones

  - by user657429

  I'm curious if it's possible to record audio from many sources and if not, what's the limitation. Many current devices have two internal microphones (basically for noise reduction). On top of that it's possible to plug additional external one using audiojack. You can as well have another audio stream via bluetooth headset. You are allowed to specify AudioSource in android but is it possible to do recording from many sources at the same time? I'm also interested how the situation look like on the iOS devices.

• use JSON variable in jQuery dynamically

  - by user1644123

  I have two DIVs, #placeholder AND #imageLoad. When the user clicks on a particular thumb its larger version (thumb2) should then appear in #imageLoad DIV. Here is the jQuery that needs to be fixed: $.getJSON('jsonFile.json', function(data) { var output="<ul>"; for (var i in data.items) { output+="<li><img src=images/items/" + data.items[i].thumb + ".jpg></li>"; } output+="</ul>"; document.getElementById("placeholder").innerHTML=output; }); //This is wrong!! Not working.. $('li').on({ mouseenter: function() { document.getElementById("imageLoad").innerHTML="<img src=images/items/" + data.items[i].thumb2 + ".jpg>"; } }); Here is the external JSON file below (jsonFile.json): {"items":[ { "id":"1", "thumb":"01_sm", "thumb2":"01_md" }, { "id":"2", "thumb":"02_sm", "thumb2":"02_md" } ]}

• IO redirect engine with metadata

  - by hawk.hsieh

  Is there any C library or tool to redirect IO and be able to configured by a metadata. And provide a dynamic link library to perform custom process for feeding data into next IO. For example, network video recorder: record video: socket do_something() file preview video: socket do_something() PCI device http service: download file: socket do_something(http) file socket post file: socket do_something(http) file serial control: monitor device: uart do_something(custom protocol) popen("zip") socket I know the unix-like OS has IO redirect feature and integrate all application you want. Even socket IO you can use /dev/tcp or implement a process to redirect to stdout. But this is process based , the process's foot print is big , IPC is heavy. Therefore, I am looking for something to redirect IO in a process and the data redirect between IO is configurable with a metadata (XML,jason or others).

• What information do you capture your software crashes in the field?

  - by Russ

  I am working on rewriting my unexpected error handling process, and I would like to ask the community: What information do you capture both automatic, and manually, when software you have written crashes? Right now, I capture a few items, some of which are: Automatic: Name of app that crashed Version of app that crashed Stack trace Operating System version RAM used by the application Number of processors Screen shot: (Only on non-public applications) User name and contact information (from Active Directory) Manual: What context is the user in (i.e.: what company, tech support call number, RA number, etc...) When did the user expect to happen? (Typical response: "Not to crash”) Steps to reproduce. What other bits of information do you capture that helps you discover the true cause of an applications problem, especially given that most users simply mash the keyboard when asked to tell you what happened. For the record I’m using C#, WPF and .NET version 4, but I don’t necessarily want to limit myself to those.

• HTML: How to get a child element to show behind (lower z-index) than its parent

  - by dclowd9901

  I need for a certain dynamic element to always appear on top of another element, no matter what order in the DOM tree they are. Is this possible? I've tried z-index (with position: relative), and it doesn't seem to work. I hate to be vague, but this is the simplest way I can think of asking this question without explaining its purpose ad nauseum. So, to recap, I need <div class="a"> <div class="b"></div> </div> <div class="b"> <div class="a"></div> </div> To display exactly the same when rendered. And for flexibility purposes (I'm planning on distributing a plugin that needs this functionality), I'd really like to not have to resort to absolute or fixed positioning.

• MySQL get row closest to NOW()

  - by Christopher McCann

  I have a table with User data such as name, address etc and another table which has a paragraph of text about the user. The reason that they are separate is because we need to record all the old about data. So if the user changes their paragraph - the old one should still be stored. Each bit of about data has a primary key aboutMeID. What I want to do is have a join that pulls their name, address etc and the latest bit of aboutMe data from the other table. I am not sure though how I can order the join to only get the latest about me data. Can someone help?

• sqlplus remove \r \n \t from spool

  - by Tom

  Hi all, Is there any sql*plus command to remove \r \n and\t from the result set that's going out to the spool file? That is, "trim" every record? We've used set trim on in the past, but it doesn't seem to bue what we need right now. I'm trying to avoid calling oracle's translate, chr functions in the sql query. For example, If my query returns this |DATA| |\n \t\t\t\t\t thisistheactualdata \t\t\t\t\t\t\n| I'd like to keep this |DATA| |thisistheactualdata| Thanks in advance.

• Rotating in OpenGL relative to the viewport

  - by Nick

  I'm trying to display an object in the view which can be rotated naturally by dragging the cursor/touchscreen. At the moment I've got X and Y rotation of an object like this glRotatef(rotateX, 0f, 1f, 0f); // Dragging along X, so spin around Y axis glRotatef(rotateY, 1f, 0f, 0f); I understand why this doesn't do what I want it to do (e.g. if you spin it right 180 degrees, up and down spinning gets reversed). I just can't figure out a way for both directions to stay left-right and up-down relative to the viewer. I can assume that the camera is fixed and looking along the Z axis. Any ideas?

• Float over two elements

  - by eWolf

  My problem is rather complex to explain, so I'll show you an example: http://ewolf.bplaced.de/misc/float.htm I want to have a floated element (the blue box) to be be placed over two other elements (red and green) and I want the whole thing to be fixed-width and centered (done by the box with the black border) while the background of the red and green box should fill the whole width. I'm actually not quite sure if the way I've done it now is XHTML/CSS valid, but it works - at least in Firefox. In IE6, the green box expands to fit the whole blue box - how can I fix this in IE6 or find another solution to show it correctly in all browsers?

• how to populate an entity you have extended in the Entity Framework?

  - by user169867

  I have an entity in my EDMX that I've extended with a few fields in a partial class like this: public partial class Employee { public string JobName {get;set;} } These properties are for display only. In the above example say the entity has a JobTypeID property. I wish JobName to be populated w/ the name that belongs to that JobTypeID. Is there anyway to query the employee record in EF including the value for the JobName property w/o explicity assigning each field using select()? The reason I ask is that there are a lot of fields in the Employee entity so I'd like to be able to take advantage of something like: ctx.Employees.Where(e=>e.EmployeeID==employeeID).Single() ...add somehow fill in JobName too Is this possible?

• How to force a WebPart to display in all pages of a portal?

  - by Mehdi

  Hi, I'm working on a portal/CMS project and (unfortunately) build the foundation on WebParts platform. However I need to provide an option for admin to choose whether a webpart should be display in all pages or not. Finally I've found a nice article from Damon Armstrong that describes a way to store all personalization data of a group of pages into one record. Thus every changes the admin made for a webpart, affect whole pages. But it doesn't seems to be a solution for me. May be it would be solved by writing a custom personalization provider, but I don't now how. Any Ideas about the problem? Thanks

• Can I do this with just SQL?

  - by Josh

  At the moment I have two tables, products and options. Products contains id title description Options contains id product_id sku title Sample data may be: Products id: 1 title: 'test' description: 'my description' Options id: 1 product_id: 1 sku: 1001 title: 'red' id: 2 product_id: 1 sku: 1002 title: 'blue' I need to display each item, with each different option. At the moment, I select the rows in products and iterate through them, and for each one select the appropriate rows from options. I then create an array, similar to: [product_title] = 'test'; [description] = 'my description'; [options][] = 1, 1001, 'red'; [options][] = 2, 1002, 'blue'; Is there a better way to do this with just sql (I'm using codeigniter, and would ideally like to use the Active Record class)?

• SQL Server pivots? some way to set column names to values within a row

  - by ccsimpson3

  I am building a system of multiple trackers that are going to use a lot of the same columns so there is a table for the trackers, the tracker columns, then a cross reference for which columns go with which tracker, when a user inserts a tracker row the different column values are stored in multiple rows that share the same record id and store both the value and the name of the particular column. I need to find a way to dynamically change the column name of the value to be the column name that is stored in the same row. i.e. id | value | name ------------------ 23 | red | color 23 | fast | speed needs to look like this. id | color | speed ------------------ 23 | red | fast Any help is greatly appreciated, thank you.
