• Tutorial needed to learn Microsoft BI

  - by Zerotoinfinite

  I am a .NET developer and have a little experience in Sql Server. As we all know that .NET developer mostly deals with stored procedures in Sql Server. I am willing to learn BI (SSIS,SSRS,SSAS) from home. I have seen some article but I don't think that's going to work for me. I am seeking some Free video tutorials I can get to learn BI. Imp: I am asking this question here because I believe that many of you are genius BI and .NET developers so you guys can help me figure out which tutorial will take benift from my .net skills. Apologize : I used free in my question. I am guilt to say that I am one of the guy who is not willing to invest but the reason is this that currently I am Jobless. :-(

• What format is your documentation in?

  - by Ek0nomik

  I am going to be writing documentation for two web services that I developed, and I started wondering what people on here do for documentation. Do you create it in an HTML file so it can be viewed in the browser? Word document? Wiki? What do you guys/gals use? I was originally leaning towards creating an HTML page since it seems a little more open and friendly than a word document. Plus I can use the prettify javascript to make code samples look nice. Our company has a Sharepoint though, so an HTML file may not be the best choice given that most documentation is put up in spreadsheets and word documents.

• Count the number of emails each day in Outlook 2003?

  - by Mat Nadrofsky

  This is for a little pet project of mine. I want to write a program that does some email analytics and tells you the number of emails coming in and out each day, as well as your percentages. Really, all I need to do to kick this off is write a .Net app that can talk with Outlook and count the number of messages received and sent for give dates. Before I got too deep into this, I figured I'd poll the group and see if there is a particular approach I should follow when starting something like this. Any thoughts?

• Is correct name enough to make it happen?

  - by Knowing me knowing you

  Guys, I've just dipped in to limits.h by MS. I tried to check what's the return type for max() fnc and to my surprise I see something like this: // TEMPLATE CLASS numeric_limits template<class _Ty> class numeric_limits : public _Num_base { // numeric limits for arbitrary type _Ty (say little or nothing) public: static _Ty (__CRTDECL min)() _THROW0() { // return minimum value return (_Ty(0)); } static _Ty (__CRTDECL max)() _THROW0() { // return maximum value return (_Ty(0));//EXACTLY THE SAME WHAT IN min<<------------------ } //... other stuff }; so how is it possiple that in both min and max return does exactly the same? So does it mean if I would write makeSanwich() return (_Ty(0)) it would make a sandwich for me? How is it possible that having this same code just fnc names different we are getting different results?

• JSP::Confused with the session objects

  - by Legend

  I just started exploring Java Servlets and JSP and am a little confused about the sessions object. Inside a servlet I have this: public class SampleServlet extends HttpServlet { public void doPost(HttpServletRequest request, HttpServletResponse response) throws IOException { HttpSession session = request.getSession(true); session.setAttribute("_session", "_value"); response.sendRedirect("page2.jsp"); } } Now, inside page2.jsp, there is a session object as well, but when I do this <% out.print(session.getAttribute("_session")) %> it gives me an error. Can someone tell me the right way of doing this? As to what I am trying to do, I want to share some session variables.

• /form making table go odd

  - by noryb009

  I have a table (3x3) that counts "< /form" as space in IE. The code for 1 td looks like: <style type="text/css"> table { border-width: 0px; border-collapse: collapse; padding: 0px; } td, th { padding: 0px; } </style> <table><tr><td><form name="form" action="index.php" method="post"><input type="hidden" name="from" value="a" /><input type="image" src="pic1.gif" alt="1" name="submit" value="submit" /></form></td> There is no spaces anywhere outside the tags. Inside the td, there is a form, with a hidden field and a picture. Firefox shows only the picture, but IE has spaces between the rows. I did a little debugging, and found it was from the /form. Does anyone know a fix to this?

• Performance: Subquerry or Joining

  - by Auro

  HelloHello I got a little Question about Performance of a Subquerry /Joining another table INSERT INTO Original.Person ( PID, Name, Surname, SID ) ( SELECT ma.PID_new , TBL.Name , ma.Surname, TBL.SID FROM Copy.Person TBL , original.MATabelle MA WHERE TBL.PID = p_PID_old AND TBL.PID = MA.PID_old ); This is my SQL, now this thing runs around 1 million times or more. Now my question is what would be faster? if I change TBL.SID to (Select new from helptable where old = tbl.sid) or if I add helptable to the from and do the joining in the where? greets Auro

• Prevent double submission of forms in jQuery

  - by Adam

  I have an form that takes a little while for the server to process. I need to ensure that the user waits and does not attempt to resubmit the form by clicking the button again. I tried using the following jQuery code: <script type="text/javascript"> $(document).ready(function(){ $("form#my_form").submit(function(){ $('input').attr('disabled','disabled'); $('a').attr('disabled','disabled'); return true; }) }); </script> When I try this in Firefox everything gets disabled but the form is not submitted with any of the POST data it is supposed to include. I can't use jQuery to submit the form because I need the button to be submitted with the form as there are multiple submit buttons and I determine which was used by which one's value is included in the POST. I need the form to be submitted as it usually is and I need to disable everything right after that happens. Thanks!

• How to know when the user touches the OK button of the last StoreKit alert "Thank you. Your purchase

  - by Walchy

  I have integrated "In App Purchase" in a game to let the user unlock more levels. Everything works fine, but I have a little problem with the last alert "Thank You. Your purchase was successful. [OK]". My program gets informed that the transaction was successfully completed before this last alert pops up and so my game starts running again - then the alert comes up, annoying the user. I would like to wait with my game running until the user touches the "OK" button, but since it is an alert from StoreKit I have no idea when this happens or how I could catch it. I don't want to create another dialog (this time my own, therefor under my control) below the alert, just asking for touching "OK" again - would be a bad user experience. Anybody have any ideas?

• Does a servlet-based stack have significant overheads?

  - by John

  I don't know if it's simply because page-loads take a little time, or the way servlets have an abstraction framework above the 'bare metal' of HTTP, or just because of the "Enterprise" in Jave-EE, but in my head I have the notion that a servlet-based app is inherently adding overhead compared to a Java app which simply deals with sockets directly. Forget web-pages, imagine instead a Java server app where you send it a question over an HTTP request and it looks up an answer from memory and returns the answer in the response. You can easily write a Java socket-based app which does this, you can also do a servlet approach and get away from the "bare metal" of sockets. Is there any measurable performance impact to be expected implementing the same approach using Servlets rather than a custom socket-based HTTP listening app? And yes, I am hazy on the exact data sent in HTTP requests and I know it's a vague question. It's really about whether servlet implementations have lots of layers of indirection or anything else that would add up to a significant overhead per call, where by significant I mean maybe an additional 0.1s or more.

• Background image Windows Phone 7

  - by Xavier

  I have a little question, I want to change the background of my application with C#. I tried this code : var app = Application.Current as App; var imageBrush = new ImageBrush { ImageSource = new BitmapImage(new Uri(imageName, UriKind.Relative)) }; app.RootFrame.Background = imageBrush; But it doesn't work, the background is dark.. I tried to do : app.RootFrame.Background = new SolidColorBrush(Colors.Blue); And it works well. So I don't understand where is the problem, my image is 480*800 px and I set Build Action to Content and Copy to Output Directory to Copy if newer . Thanks for all

• Random walk- Brownian Motion

  - by Sam

  I've been assigned the project of creating a simple console app. that models brownian motion in a 2D plane. I wasn't given much information on how to do so (and I'm hoping that it's a pretty popular assignment so that I could get some insight) just that it relies on random number generation. I researched brownian motion for a little bit and saw some formulas that looked complicated, but by the description is just seems to have to move randomly within a certain number interval. Can anyone clarify? Am I to create a program that continually creates a random number in an interval and then modify the particles "x" and "y" coordinate or is there more to it? Thanks for any help.

• ruby hash to object - Parsing data from JSON object

  - by Leddo

  Hi all, I'm just starting to dabble in consuming a JSON webservice, and I am having a little trouble working out the best way to get to the actual data elements. I am receiving a response which has been converted into a ruby hash using the JSON.parse method. The hash looks like this: {"response"=>{"code"=>2002, "payload"=>{"topic"=>[{"name"=>"Topic Name", "url"=>"http://www.something.com/topic", "hero_image"=>{"image_id"=>"05rfbwV0Nggp8", "hero_image_id"=>"0d600BZ7MZgLJ", "hero_image_url"=>"http://img.something.com/imageserve/0d600BZ7MZgLJ/60x60.jpg"}, "type"=>"PERSON", "search_score"=>10.0, "topic_id"=>"0eG10W4e3Aapo"}]}, "message"=>"Success"}} What I would like to know, is what is the easiest way to get to the "topic" data so I can do something like: topic.name = json_resp.name topic.img = jsob_resp.hero_image_url etc Many thanks for any help you can offer.

• Image analysis on the iPhone

  - by user362808

  Hi, guys! Hopefully a quick one. Working on a devious little algorithm that'll automatically scan a user's iPhone for a photo of some emotional poignance (e.g. go back in time a ways, look for one of a group of photos that are proximally timestamped, etc.). Need a quick-and-dirty way of picking out a photo containing two people in close proximity to each other. I know that the OpenCV Python lib [for image processing] works on the iPhone, I'm just curious whether it's actually the best way of doing this (from scratch or otherwise). Cheers!

• Can I learn the iPhone SDK and complete an app by September?

  - by Kuro

  Hi everyone, I'm wondering if it's realistically possible to learn the iPhone SDK and complete an app by the end of this summer. The app shouldn't be too difficult, it would just interact with my site's API and essentially just fetch, create, and edit resources. I already have a little experience with the SDK (and I'm comfortable with Objective-C), so I'm not completely new to it. Although here I things I don't know how to do and what I'd need to learn: Log in to my site using basic http authentication and store the user's username/password for all future requests Implement a toolbar at the bottom to navigate between different views Fetch and parse xml into list items Do POST/PUT requests to create/edit a resource on my server Are there any good resources available to learn how to do those tasks above? Thanks!

• Help constructing query - Compare columns and replace numbers

  - by Tommy

  I have a feeling that this query is pretty easy to construct, I just can't figure it out. I want to replace all numbers in table X column C, with numbers in table Z column A, where numbers from table X column C matches numbers in table Z column B. I hope that makes sense. Perhaps a little background information will make it clearer. I've converted from one CMS to another, and the module I used to convert mapped the ids to the new database. Table X column A is the new id's. Table X column B is the old id's. Table Z is the table for an image gallery that I migrated, and column C contains the id's of the images owners. Can anyone crack this nut?

• What things can I teach a group of children about programming in one day?

  - by Rich Bradshaw

  I'm running a day for 30 kids aged 11-18 about computer game programming. They have all opted to do it, but they have no experience at all of programming. My main aim is for them to learn a few things: programming is hard/challenging programming is something they can learn to do being a computer games programmer != playing games all day a little more insight into how games actually work I'd thought of splitting them into two groups, of younger/less experience and older/more experience, then doing slightly different things. I'd considered showing them Scratch, Game Maker, before showing them the basics of Python and getting them to write a simple text based game (perhaps something like, computer picks a random number, you have to guess it in as few guesses as possible, computer says higher/lower for each guess). Does anyone have any ideas of things to do/show them/ways to teach them?

• What is an instance of a field called?

  - by waxwing

  This might be an odd question, but it has actually caused me some headache. In Object oriented programming, there are accepted names for key concepts. In our model, we have classes with methods and fields. Now, going to the data world: An instance of a class is called an object. An instance of a field is called... what? A value? Isn't the term value a little broad for this? I have been offered "property" as well, but isn't property also part of the model and not the data? (This is not purely academic, I am actually coding these concepts.)

• How to implement a set ?

  - by nomemory

  I want to implement a Set in C. Is it OK to use a linked list, when creating the SET, or should I use another approach ? How do you usually implement your own set (if needed). NOTE: If I use the Linked List approach, I will probably have the following complexities for my operations: init : O(1); destroy: O(n); insert: O(n); remove: O(n); union: O(n*m); intersection: O(n*m); difference: O(n*m); ismember: O(n); issubset: O(n*m); setisequal: O(n*m); O(n*m) seems may be a little to big especially for huge data... Is there a way to implement my Set more efficient ?

• how to make complex selectors with 'this' jquery

  - by Stomped

  I have an event handler that needs to do something to one of its children, based on some saved data. So what I'm currently doing is something like this: // Get the ID of 'this' item_id = $(this).attr('id'); // building a selector like $('#item1 .child_3') $('#' + item_id + ' .child_' + spVal).addClass('blah'); But this seems a little cumbersome. I've tried: $(this + ' .child_' + spVal).addClass('blah'); and it doesn't work, which doesn't really surprise me. Is there a better way to do this then the successful way I've outlined above?

• Using PHP to determine if a remote file has been replaced?

  - by Rob

  I have a MySQL database with some URLs in it. One URL per row. Each URL has my script on it. What I am wanting to do, is check if the file is still there via a PHP script. Not check if it 404'd, but rather check if it has been modified or replaced. Is this possible? If so, how would it be accomplished? I was thinking making the remote file echo some string, and having the local file check the page for that string, but that seems a little inefficient and sloppy.

• What is the best signature for overloaded arithmetic operators in C++?

  - by JohnMcG

  I had assumed that the canonical form for operator+, assuming the existence of an overloaded operator+= member function, was like this: const T operator+(const T& lhs, const T& rhs) { return T(lhs) +=rhs; } But it was pointed out to me that this would also work: const T operator+ (T lhs, const T& rhs) { return lhs+=rhs; } In essence, this form transfers creation of the temporary from the body of the implementation to the function call. It seems a little awkward to have different types for the two parameters, but is there anything wrong with the second form? Is there a reason to prefer one over the other?

• Is there a way to only have StyleCop documenation requirements SA1600 on public methods/properties?

  - by AlSki

  I've been using XMLDoc for a few years now, and have definitely grown into the mindset for supplying quality documentation for public methods and properties. However under StyleCop (and particularly its Resharper highlighting) I've noticed that the documentation requirements apply to identically to public, internal, protected and private methods. This seems a little counter-intuative to me, so I would ideally like to suppress it down to suggestions at least for private methods. Unfortunately it does seem as if the suppress setting is only across all public, internal, private, etc. Am I missing something or is this by design?

• Split Entire Hash Range Into n Equal Ranges

  - by noxtion

  Hello. I am looking to take a hash range (md5 or sha1) and split it into n equal ranges. For example, if n=5, the entire hash range would be split by 5 so that there would be a uniform distribution of key ranges. I would like n=1 to be from the beginning of the hash range to 1/5, 2 from 1/2 to 2/5, etc all the way to the end. I am new to hashing and a little bit unsure of where I could start on solving this for a project. Any help you could give would be great.
