  • SQL Analysis Services - Dimension attributes with a "many" cardinality

    - by MonkeyBrother
    I am creating a cube with the following tables: Customer CustomerID, Name Customer Rep CustomerID, RepID Rep RepID, Name The important thing here is that there is a many to many relationship between Reps and Customers. I want to be able to ask the question "How much sales for customers working with rep 'A'?" In the data source view i set up the relationships between both customerid columns and both repid columns. I set up the rep attribute in the dimension builder and when I try to build the cube I get this error: Errors in the high-level relationship engine. the 'Rep' table that is required for a join cannot be reached based on the relationships in the data source view.

  • Database suggestion

    - by superartsy
    I am working on an enterprise level product that is designed around SQL Express Database ( views,concurrent users,stored procedures,case,IF).Though we dont use any SQL Server advanced features, if the database size of 4Gb in express ends up being a limitation customers can move to advanced versions of SQL Server. However my problem is, SQL Express deployment is not easy and the installer size is huge. This is a major drawback for someone looking to try our product.You dont want end users to not buy a product becos the download is huge. Does anyone have any recommendations of a database that has a smaller footprint but all the features of Express and which can be migrated to express?

  • Using variables in Tasker

    - by Waza_Be
    I am trying to create a Tasker plugin. Everything is fine, and works pretty well. I can configure a String to be sent in my app by using EditActivity and this code, following the examples: resultIntent.putExtra(com.twofortyfouram.locale.Intent.EXTRA_BUNDLE,PluginBundleManager.generateBundle(getApplicationContext(),message)); resultIntent.putExtra(com.twofortyfouram.locale.Intent.EXTRA_STRING_BLURB,generateBlurb(getApplicationContext(), message)); setResult(RESULT_OK, resultIntent); The problem comes when I want to use this code to get the battery level for instance, so I added: resultIntent.putExtra("net.dinglisch.android.tasker.extras.VARIABLE_REPLACE_KEYS",com.twofortyfouram.locale.Intent.EXTRA_STRING_BLURB); but the app is not working and I get a string %BATT as the result, the variable is not replaced... As I haven't found any example, I would be pleased to get some help to make it work.

  • How to use SQLiteOpenHelper without or less restrictive use of Context?

    - by Pentium10
    If you extend SQLiteOpenHelper, for the Constructor you have to use a Context. I am wondering if there is a way to leave this out, and be able to work with database tables without a Context. Or at least be least restrictive, I mean a way of project/class structure that will make history the several context passings I have to do now. As it is my application has several level of classes, chained in each other, and there are a few that connects to the database, but have no whatsoever influence on the interface, so they don't actually need the Context. Are you creating your classes in the way that you pass each time a Context to them? If not, how you do, how you reuse a Context in a short class?

  • (C#) How do you de-elevate permissions for a child process

    - by Davy8
    I know how to launch a process with Admin privileges from a process using: proc.StartInfo.UseShellExecute = true; proc.StartInfo.Verb = "runas"; where proc is a System.Diagnostics.Process. But how does one do the opposite? If the process you're in is already elevated, how do you launch the new process without admin privileges? More accurately, we need to launch the new process with the same permission level as Windows Explorer, so no change if UAC is diabled, but if UAC is enabled, but our process is running elevated, we need to perform a certain operation un-elevated because we're creating a virtual drive and if it's created with elevated permissions and Windows explorer is running unelevated it won't show up. Feel free to change the title to something better, I couldn't come up with a good description

  • null pointer exception on list.add

    - by Eric
    I've been working on this one error for a few hours so I thought I'd pick the brains of some pros. I am getting a null pointer exception at the modelData.add(i, es) method. I know from debugging that es isn't null. I'm really confused, thanks. public class EventTableModel extends AbstractTableModel { //private int rowCount = 0; protected List<EventSeat> modelData; private static final int COLUMN_COUNT = 3; private Event e; Event j = GUIpos.m; int i = 1; public EventTableModel(Event e) { this.e = e; try { System.out.println(modelData); for (EventSeat es : e.getEventSeats()) { modelData.add(i, es); i++; } } catch (DataException ex) { Logger.getLogger(EventTableModel.class.getName()).log(Level.SEVERE, null, ex); } }

  • How to get REALLY fast python over a simple loop

    - by totallymike
    I'm working on a spoj problem, INTEST. The goal is to specify the number of test cases (n) and a divisor (k), then feed your program n numbers. The program will accept each number on a newline of stdin and after receiving the nth number, will tell you how many were divisible by k. The only challenge in this problem is getting your code to be FAST because it k can be anything up to 10^7 and the test cases can be as high as 10^9. I'm trying to write it in python and having trouble speeding it up. Any ideas? import sys first_in = raw_input() thing = first_in.split() n = int(thing[0]) k = int(thing[1]) total = 0 i = 0 for line in sys.stdin: t = int(line) if t % k == 0: total += 1 print total

  • Examples of both beautiful and ugly java code?

    - by tputkonen
    I would like to demonstrate how difficult it is for a layman to identify high quality code from flawed code. I'm thinking of doing this with the help of two java methods. Both of the methods should look like they do the same, pretty simple thing. However one of them should have several kind of flaws, for example: iteration with array off by one error string concatenations causing lots of objects to be created (as opposed to StringBuffer in the "good" code, which looks more complicated) possibly null pointer exception (but it should not be trivial to spot) Those are just some examples, all kinds of other issues including bugs and performance related structures are highly appreciated. Methods should be around 10-20 lines of length, and the task they do should be something simple - preferably printing something in an iteration.

  • Library for Dataflow in C

    - by msutherl
    How can I do dataflow (pipes and filters, stream processing, flow based) in C? And not with UNIX pipes. I recently came across stream.py. Streams are iterables with a pipelining mechanism to enable data-flow programming and easy parallelization. The idea is to take the output of a function that turns an iterable into another iterable and plug that as the input of another such function. While you can already do this using function composition, this package provides an elegant notation for it by overloading the operator. I would like to duplicate a simple version of this kind of functionality in C. I particularly like the overloading of the operator to avoid function composition mess. Wikipedia points to this hint from a Usenet post in 1990. Why C? Because I would like to be able to do this on microcontrollers and in C extensions for other high level languages (Max, Pd*, Python). * (ironic given that Max and Pd were written, in C, specifically for this purpose – I'm looking for something barebones)

  • How do I set font size to 0px in IE6?

    - by Justin808
    I have an unordered list, I'm trying to hide the text in the list. I can do this 2 ways that i know of: font-color: transparent; font-size: 0px; I prefer the 0px method as its not selectable. This issue is neither way works in IE6. The first way just doesn't work in IE6 at all, the 2nd leave a 1PX high font. Is there a way to hide the text in IE6? This is a visual thing, I know you can read the text by reading the source and that is OK, I just need it to visually not be there.

  • Google Maps API v3.9: Blurry custom markers when zooming

    - by Mike
    So it appears that Google have fixed the blurry map issue with the 3.9 / 3.10 API, which is great. But there's a new one with custom markers. As soon as you zoom in one level, the custom markers become corrupted / blurry. They rectify themselves if zooming out, although the process of zooming out also makes the markers slightly blurry. The 3.8 API does not exhibit this problem with custom markers. Here's a picture illustrating the problem (I suggest you open the image in a new tab; the blurriness isn't as easily visible when the image is scaled to fit this post). The blurring is most noticeable with the straight lines of the paper crane marker: I've had a prod through the HTML, but I can't really tell how the markers are placed on the map. But I thought that I'd put this issue out there for anyone who has experienced similar, or if anyone has any thoughts on how this can be resolved, save waiting to see if it's a glitch in the API.

  • Python: Best practice for including a version number in an app?

    - by Ben
    I have a PyQt application that reads and writes data files. I am including a 'version number' in each file written. This is a simple number similar to: 1.2 or something (major and minor versions). I am doing this so that I can change the format of these data files in future versions and then still correctly parse them simply by checking to see what the version is inside the file. My question is what is the best practice for keeping this number stored inside the app itself. I.e. do I just hard-code the app version number into the class that is responsible for reading and writing files? Or should I have some sort of object/variable stored at the top-level of the app and somehow access it from the class responsible for reading and writing these files. If the latter, how do I store it and how do I access it? Thanks.

  • gzinflate erroring

    - by Rob
    Well, I'm trying to gzdeflate my code to perform some very low level encryption for distribution, to use with eval(gzinflate('deflated_code')); However whenever I try to inflate the deflated string, it outputs an error. For example: echo(gzdeflate('test')); outputs +I-.? But when I try to echo(gzinflate('+I-.?')); it only outputs Warning: gzinflate() [function.gzinflate]: data error Is there something I'm missing? Why is it outputting this error rather than test?

  • Retlang: What is the best way to unsubscribe from a channel?

    - by TrickyFishy
    I'm not sure what is the best way to unsubscribe from a channel when using Retlang. When you subscribe by calling ISubscriber<T>::Subscribe(...) you are returned an IUnsubscriber. This interface has no methods. Going up a level, IChannel<T> also does not have any methods. The only thing I can think of is casting an ISubscriber<T> to the concrete Channel<T> and calling its Unsubscribe() method or adding an Unsubscribe() method to ISubscriber<T>. I'm just curious if anyone knows what they had in mind before I modify the code.

  • Windows batch file: Pipe destroys my return code

    - by murxx
    Hi, is it possible to return the errorlevel also if I pipe the output of a script into a logfile: test1.bat: call test2.bat 2>&1 | tee log.txt echo ERRORLEVEL: %ERRORLEVEL% test2.bat: exit /B 1 Output when calling test1.bat: ERRORLEVEL: 0 The errorlevel is always 0. The problem is, I want to call another script inside my script where the output should be redirected synchronously with the output shown in the command line, therefore a simple is not enough for me. I tried several ideas, but result is that the pipe always seems to destroy the given error-level... :( Can you give me any further suggestions? Thanks in advance... :)

  • custom form with Drupal - CCK and simple module - what next?

    - by bert
    I have mastered creating custom data types and adding fields with CCK. Then I created and deployed a custom module with _form and _validate and _submit hooks. I am not happy with the amount of massaging required with css and permissions to make the form usable, but this is not my question. Now I would like to create a more sophisticated form with jquery to submit form and add content to page. I am at a bit of loss as how to get to this next level. I have been looking at tpl.php files, but this looks very rigid and more complicated as well. Can any provide a model or tutorial or point me in right direction.

  • What's a good FOSS java servlet session replication solution

    - by Bossy Joe
    I work on a very high volume public website running on Tomcat 5.5. Currently we require stickiness to a particular server in order to maintain session. I'd like to start replicating session, but have had trouble finding a good FOSS solution. I've written my own Manager (using memcached as the store) but am having trouble dealing with race conditions if more than one server is handling the requests for the same user. Is there a solution out there I should be looking at? I'm looking for not just something that works as a fallback if stickiness fails, but that would work if user requests are regularly spread to multiple servers.

  • How SqlDataAdapter works internally?

    - by tigrou
    I wonder how SqlDataAdapter works internally, especially when using UpdateCommand for updating a huge DataTable (since it's usually a lot faster that just sending sql statements from a loop). Here is some idea I have in mind : It creates a prepared sql statement (using SqlCommand.Prepare()) with CommandText filled and sql parameters initialized with correct sql types. Then, it loops on datarows that need to be updated, and for each record, it updates parameters values, and call SqlCommand.ExecuteNonQuery(). It creates a bunch of SqlCommand objects with everything filled inside (CommandText and sql parameters). Several SqlCommands at once are then batched to the server (depending of UpdateBatchSize). It uses some special, low level or undocumented sql driver instructions that allow to perform an update on several rows in a effecient way (rows to update would need to be provided using a special data format and a the same sql query (UpdateCommand here) would be executed against each of these rows).

  • Bandwidth Monitoring in asp.net

    - by asifch
    HI, We are developing a multi-tenant application in Asp.Net with separate DB for each tenant, in which one of the requirement is to monitor the bandwidth usage for each tenant, i have tried to search but not found much help on the topic,we want to monitor exactly how much bandwidth is being used for each tenant while each tenant can have its own top level domain or a sub domain or a combination of both. so what are the available options, the ones which i can think of can be 1. IIS Log Monitoring means a separate application which will calculate the bandwidth for each tenant. 2. Log Each Request and Response for a tenant from within the application and then calculate the total bandwidth usage based on that. 3. Use some third part components if available So what do you think will be the best approach, also if there is any other way to do this.

  • How to detect time on a playing Flash video

    - by 6bytes
    Hi I have a video playing on my page. I want to show and hide some div's when the video reaches a certain point. Lets say hide something on 10th second and show it again on 20th second. I can easily do it in HTML5 with video tag and currentTime attribute but for IE I have to create the same functionality and I think with flash based videos (from YouTube or something like that). Is there a way to detect the current time of a video playing on my website, embeded from YouTube, Metacafe or any other video sharing site? I know I could detect it in flash and make it run some JavaScript function but I don't have flash nor have the skills to do it in AS3. Is it possible to do it from JavaScript level or does any video sharing website out there provides this kind of functionality for their videos?

  • Erlang Question - Time order of messages

    - by Aiden Bell
    Read (skimmed enough to get coding) through Erlang Programming and Programming Erlang. One question, which is as simple as it sounds: If you have a process Pid1 on machine m1 and a billion million messages are sent to Pid1, are messages handled in parallel by that process (I get the impression no) and(answered below) is there any guarantee of order when processing messages? ie. Received in order sent? If so, how is clock skew handled in high traffic situations for ordering? Coming from the whole C/Thread pools/Shared State background ... I want to get this concrete. I understand distributing an application, but want to ensure the 'raw bones' are what I expect before building processes and distributing workload. Also, am I right in thinking the whole world is currently flicking through Erlang texts ;)

  • Unsafe, super-fast cross-process memory buffer?

    - by John
    Cross-process memory buffers always have some overhead, and my understanding is this is quite high. But what if you're implementing a cross-process render-buffer, this isn't critically important in the same way as other data so are there techniques we can use to get 'raw' access to a chunk of memory from multiple processes, with no safety nets apart from it not crashing? Or do modern operating systems simply not work with unabstracted memory in a way to make this possible? I'm working in C++ but the question applies to Win XP/Vista/7, MacOSX 10.5+ (& Linux less importantly).
