  • MDX filter members in a sum-function

    - by Radagast2005
    I have an SSAS cube containing customers and their purchased memberships (let's say magazines). I want to calculate the retention. I.e. how many customers remain a customer. To do this I specify a set (males, 30yrs, 1 january 2011). I want to see if this set - identified by a customer number - is still present in the following months. I named my set MySet2. What I try to do is: sum(measures.amount, [membership].[name].&[X], MySet2, [date].[date].currentmember) However, the result is incorrect. The number is far to low. I suspect it still tries to account for all the males of 30 years old, but after a year they're not 30 anymore. What am I missing? I looked at scope and filter, but I'm not sure how to apply it.

  • Suggest changes to make the time a function of input size

    - by KB
    Vector v; int i=0; while(i!=999) { cini; v.push_back(i); } Time taken by this piece of code could vary when the number of inputs vary. Since vector would take amortized time for new allocation. Even for same size the program at different times could take different time. Suggest changes (e.g. use list instead of vector), which makes the time a function of number of inputs.

  • What's an easy way of storing an array of numbers in Javascript that I can add/remove from?

    - by SLC
    In C# I would create a List then I could add and remove numbers very easily. Does identical functionality exist in Javascript, or do I have to write my own methods to search and remove items using a loop? var NumberList = []; NumberList.Add(17); NumberList.Add(25); NumberList.Remove(17); etc. I know I can use .push to add a number, so I guess it's really how to remove an individual number without using a loop that I'm looking for. edit: of course, if there's no other way then I'll use a loop!:)

  • Jquery how to test if current hovered div is eq(x)

    - by j-man86
    Hi all! I am trying to create a jQuery hover function that will highlight a different section of the page depending on what number EQ (index position number) the div is. $('#photoContent div').hoverIntent(function () { if( $(this).filter(':lt(5)') ) { $('#photoSidebar').find('p:eq(0)').addClass('currentPhoto'); } if( $(this).filter(':gt(5)') ) { $('#photoSidebar').find('p:eq(1)').addClass('currentPhoto'); } }, function () { $('#photoSidebar').find('p').removeClass('currentPhoto'); }); The above code obviously does not work, but the concept/functionality is what I'm going for. Thanks for your help!

  • Microformats, Reviews and Duplicate Content

    - by Nicholas
    Let's say I have a site that sells widgets, and the URL structure is like so: /[type-of-widget]/[sub-type]/[widget-name]/ So, a URL for a widget might be: /screwdrivers/philips-screwdrivers/acme-big-screwdriver/ We show reviews on the widget page, and use the appropriate microformat data so Google knows it's a review, etc. Now, what if I want to show random reviews in the "sub-type" and "type-of-widget" landing pages? Will Google ding me for duplicate content, or is it smart enough to know (based on microformat data/etc.) that this is not duplicate content?

  • How do I create an image for a UITableViewCell dynamically

    - by Xetius
    I want to dynamically create an image for a UITableViewCell which is basically a square with a number in it. The square has to be a colour (specified dynamically) and contains a number as text inside it. I have looked at the CGContextRef documentation, but can't seem to work out how to get the image to fill with a specified certain colour. This is what I have been trying so far. -(UIImage*)createCellImageWithCount:(NSInteger)cellCount AndColour:(UIColor*)cellColour { CGFloat height = IMAGE_HEIGHT; CGFloat width = IMAGE_WIDTH; UIImage* inputImage; UIGraphicsBeginImageContext(CGSizeMake(width, height)); CGContextRef context = UIGraphicsGetCurrentContext(); UIGraphicsPushContext(context); // drawing code goes here // But I have no idea what. UIGraphicsPopContext(); UIImage* outputImage = UIGraphicsGetImageFromCurrentImageContext(); UIGraphicsEndImageContext(); return outImage; }

  • Sql Distinct Count of resulting table with no conditionals

    - by AfterImage
    Hello everyone, I want to count the number of accounts from the resulting table generated from this code. This way, I know how many people liked blue at one time. Select Distinct PEOPLE.FullName, PEOPLE.FavColor From PEOPLE Where FavColor='Blue' Lets say this is a history accounting of what people said their favorite color when they were asked so there may be multiple records of the same full name if asked again at a much later time; hence the distinct. The code I used may not be reusable in your answer so feel free to use what you think can work. I am sure I found a possible solution to my problem using declare and if statements but I lost that page... so I am left with no solution. However, I think there is a way to do it without using conditionals which is what I am asking and rather have. Thanks. Edit: My question is: From the code above, is there a way to count the number of accounts in the resulting table?

  • Is there a canonical source for learning C# and .NET internals?

    - by ta269uec
    I have been a C++ programmer for last several years with a bit of C# here and there. In my latest job, I work heavily on C#. I picked most of my C# by following the code-base or random google searches on what I wanted to do at that point (like threading in C#). I feel a time has come to invest some time into understanding the language internals and also understanding the .NET framework from an architectural point of view. Can someone recommend the "gold standard" text/resource for accomplishing these? What about that resource makes it the best? What were your experiences with it?

  • How do I remove specific numbers from a string?

    - by user1666900
    I have this string in PHP Hopelessly Incredible |SPG:M| 766 STEAM_0:1:20130600 " banned "A Blatantly Obvious Hacker 740 STEAM_0:1:55386073 " (minutes "0") (reason "Multi-Hack") The Format of the string is: Name1 Number(0-3 digits) Steam_0:x:xxxx offense (banned/kicked/mute etc) Name2 Number(0-3 digits) Steam_0:x:xxxx time reason My goal is to remove the values 766 and 740 because it is just garbage. Those values can have single, double, and triple digits. The next step would be to strip STEAM_0:1:20130600 and STEAM_0:1:55386073 out of the string and capture it in a new variable. The only constant is STEAM_0: the rest can change. I am still learning regex but I fear this is a bit complicated for me to do. Some guidance would be most appreciative.

  • How To Deliberately Hide Bugs In Code (for use in a Novel I'm writing) [closed]

    - by Dennis Murphy
    I'm writing a novel in which an evil programmer wants to include subtle errors in his code that are likely to go unnoticed by his supervisor during a code review and unlikely to be caught by a compiler, yet cause damage at possibly random times when the program is executed by an end-user. I only need a couple of examples, which may be exotic but which have to be easily explainable to non-technical readers. Procedural or object-oriented examples would be equally helpful. (It's been a VERY long time since I've written any code.) Thanks for your help.

  • Calculating very large exponents in python

    - by miraclesoul
    Dear All, Currently i am simulating my cryptographic scheme to test it. I have developed the code but i am stuck at one point. I am trying to take : g**x where g = 256 bit number x = 256 bit number Python hangs at this point, i have read alot of forums, threads etcc but only come to the conclusion that python hangs, as its hard for it to process such large numbers. any idea how can it be done? any two line piece of code, any library, anything that can be done.(ALSO PLEASE I AM A NEW PYTHON USER AND THIS IS FIRST TIME I DID PROGRAMMING IN IT, SO NO COMPLEX METHODS ...HOPE YOU UNDERSTAND :s)

  • Debug error in NetBeans

    - by avd
    I am running a C program in NetBeans (cygwin on windows). Generally for all C programs I have run in the past, while debugging, it stops and shows the line number of segmentation fault. But for this particular program, it does not show the line number and just stops and in the output tab, it shows prog stopped by SIGSEGV. I have tried conditional breakpoint, but it is not stopping. What could be the other conditions for error? If u want have a look at my program, here it is.http://codepad.org/cujYTIeg and the in.txt file from where it reads the input. http://codepad.org/vNySA6uh

  • VirtualBox - Install Windows 7 freeze on expading files

    - by spauny
    I'm using Kubuntu 12.10. I have the latest version of VirtualBox(4.2.4) with expansions installed and guest addition also. I'm trying to install Windows 7 but it freezes at the second step: expanding files (random percent). I even tried to install Vista but is happening the same thing. Is there a bug? Do you happen to know a workaround? Or at least there is another free virtual machine I can use to install win 7?

  • How to create wordpress-like option table and get values for each row?

    - by Nacho
    Hi guys. I'm looking to create an options table in my db that makes every record a system option, so I can work with a little number of fields. My db has the following structure: 3 columns named id, name, and value The following data is inserted as an example: +--+-----------+--------------------------+ |id|name |value | +--+-----------+--------------------------+ | 1|uri |www.example.com | | 2|sitename |Working it out | | 3|base_folder|/folder1/folder2/ | | 4|slogan |Just a slogan for the site| +--+-----------+--------------------------+ That way I can include a large number of customizable system options very easily. The problem is that I don't know how to retrieve them. How do I get the value of uri and store it as a var? And better yet, how do I get, for exmaple, values of id 1 and 4 only without making a query each time? (I assume multiple queries are useless and a pretty ugly method.) I know the question is pretty basic but I'm lost here. I'd really appreciate your answer!

  • python function that returns a function from list of functions

    - by thkang
    I want to make following function: 1)input is a number. 2)functions are indexed, return a function whose index matches given number here's what I came up with: def foo_selector(whatfoo): def foo1(): return def foo2(): return def foo3(): return ... def foo999(): return #something like return foo[whatfoo] the problem is, how can I index the functions (foo#)? I can see functions foo1 to foo999 by dir(). however, dir() returns name of such functions, not the functions themselves. In the example, those foo-functions aren't doing anything. However in my program they perform different tasks and I can't automatically generate them. I write them myself, and have to return them by their name.

  • A program where user enters a string and the program counts the instances of the letters

    - by user1865183
    This is the first C++ program I have ever written and I'm having trouble understanding the order in which operands must be put in. This is for a class, but it looks like I'm not supposed to use the homework tag. Sorry if I'm doing this wrong. This is my input // Get DNA string string st; cout << "Enter the DNA sequence to be analysed: "; cin >> st; This seems to work ok, but I thought I would include it incase this is what I'm doing wrong. This is what I have so far to check that the input is exclusively C,T,A, or G. It runs through the program and simply prints "Please enter a valid sequnce1, please enter a valid sequence2, ... ect. I'm sure I'm doing something very stupid, I just can't figure it out. // Check that the sequence is all C, T, A, G while (i <= st.size()){ if (st[i] != 'c' && st[i] != 'C' && st[i] != 'g' && st[i] != 'G' && st[i] != 't' && st[i] != 'T' && st[i] != 'a' && st[i] != 'A'); cout << "Please enter a valid sequence" << i++; else if (st[i] == c,C,G,t,T,a,A) i++; The second half of my program is to count the number of Cs and Gs in the sequence for (i < st.size() ; i++ ;); for (loop <= st.size() ; loop++;) if (st[loop] == 'c') { count_c++; } else if (st[loop] == C) { count_c++; } else if (st[loop] == g) { count_g++; } else if (st[loop] == G); { count_g++; } cout << "Number of instances of C = " << count_c; cout << "Number of instances of G = " << count_g; It seems like it's not looping, it will count 1 of one of the letters. How do I make it loop? I can't seem to put in endl; anywhere without getting an error back, although I know I'll need it somewhere. Any help or tips to point me in the right direction would be greatly appreciated - I've been working on this code for two days (this is embarrassing to admit).

  • How to avoid Modal Storyboard infinite loop

    - by misthills
    I've written a number of iOS applications a year ago on an old version of Xcode. I've just started a new project and discovered the storyboard feature in the latest Xcode. It turns out this is perfect for the application I am writing as it consists of ~30 interlinked screens. My question is, how do I structure my storyboard and segues to allow my application to follow a circular path through my screens. I have seen a number of examples that simply segue screen 1 to screen 2 and then screen 2 to screen 1 using the modal option. This clearly works but when I debug an application built this way, it instantiates a new instance of each screen (view controller) for every segue performed. In the diagram below (apologies, I drew a nice picture but due to my newbie status, was not able to post it), how do I go from screen 1 to screen 2 to screen 3 and back to original screen 1 without creating a new instance? // Screen 1 --> Screen 2 --> Screen3 // ^ | // | | // +-------------------------+

  • (Wordpress) Global variable to detect pagination?

    - by Gnee
    I am showing 6 posts on one page. On the 7th post, pagination occurs on so on. goal: If there is more than one page (page 1, 2, 3, etc..), JavaScript is to add a specific div element. If there are only 6 posts or less, no pagination occurs, no div element is added. The number of posts to show: $showposts = get_query_var('showposts'); The current post number I can keep track of: $post_count++; Problem is I can keep track of posts 1-6 but how to tell if if it goes over to 7 and starts pagination? I thought there was a global variable that returns if pagination occurs, but I can't seem to find it. (I know there is global to detect pagination via <!--nextpage--> but so far I can't find it's equivalent for index.php).

  • Python CSV file processing

    - by kingwarchief
    I just got introduced to python, the first language I get to learn, and I have this question below: I have an excel based CSV file with two columns (or rows, Pythonically) that I am working on. What I need to do is to perform some operations so that I can compare the two data entries in each 'row'. To be more precise, one column has constant numbers all the way down, whereas the other column varies. So I need to count the number of times the varying column data entry values crosses the constant value on the other column. For example: Varying Column; Constant Column 24 25 26 25 crosses 27 25 26 25 25.5 25 23 25 crossed 26 25 crossed So in this case the number of times there is a cross
