• SSRS Issue: Rounding to nearest .25

  - by D.R.

  I have an SSRS (2008) report that takes in a raw transactions, then groups and totals them. At the "Total" level, I would like to round the final numbers to the nearest .25, however I cannot find a method to do this. According to what I've read, the Round() function in SSRS only rounds to integers. I have found a couple ways to do it in SQL, but the problem is, I want to do all the calculations with the REAL numbers and just round the result so that I don't introduce a significant amount of error from the real numbers. Here's the best SQL solution I could find: dec(round(number * 4, 0)/4,11,2) as Nearest_Qtr Anyone know how I could do the equivalent in the actual SSRS report? Thanks in advance for the help!

• Writing custom Django form fields and widgets

  - by hekevintran

  Django has very good documentation that describes how to write custom database fields and custom template tags and filters. I cannot find the document that describes how to write custom form fields and widgets. Does this document exist? The way I've been able to write custom form fields and widgets is by reading the Django source code and imitating what I see there. I know that there are still things about implementing fields and widgets that I do not completely understand because I have not read any high level document that describes their interfaces.

• Space requirements of a merge-sort

  - by Arkaitz Jimenez

  I'm trying to understand the space requirements for a Mergesort, O(n). I see that time requirements are basically, amount of levels(logn) * merge(n) so that makes (n log n). Now, we are still allocating n per level, in 2 different arrays, left and right. I do understand that the key here is that when the recursive functions return the space gets deallocated, but I'm not seeing it too obvious. Besides, all the info I find, just states space required is O(n) but don't explain it. Any hint? function merge_sort(m) if length(m) = 1 return m var list left, right, result var integer middle = length(m) / 2 for each x in m up to middle add x to left for each x in m after middle add x to right left = merge_sort(left) right = merge_sort(right) result = merge(left, right) return result

• Keeping track of dirty blocks on a block device

  - by mikeY

  I'm looking for a way to keep track of what blocks on a block device are modified after a point in time. How I eventually want to use this for is to keep two 2TB disks in sync, one which only comes online (connected through USB) once a month. Without knowing what blocks have been modified, I have to go through the whole 2TB every time. I'm using a recent GNU/Linux OS and have C and Python experience. I'm hoping to avoid writing kernel level code as I don't have any experience in that area whatsoever. My current theory is that there should be some hooks somewhere where my code can get called when a disk flush is performed. Any ideas?

• Can't delete a mySQL table. (Error 1050)

  - by doublejosh

  I have a pesky table that will not delete and it's holding up my dev environment refresh :( I know this table exists. Example... mysql> select * from uc_order_products_qty_vw limit 10; +-----+-------------+---------+---------+---------+---------+ | nid | order_count | avg_qty | sum_qty | max_qty | min_qty | +-----+-------------+---------+---------+---------+---------+ | 105 | 1 | 1.0000 | 1 | 1 | 1 | | 110 | 5 | 1.0000 | 5 | 1 | 1 | | 111 | 1 | 1.0000 | 1 | 1 | 1 | | 113 | 5 | 1.0000 | 5 | 1 | 1 | | 114 | 1 | 1.0000 | 1 | 1 | 1 | | 115 | 1 | 1.0000 | 1 | 1 | 1 | | 117 | 2 | 1.0000 | 2 | 1 | 1 | | 119 | 3 | 1.3333 | 4 | 2 | 1 | | 190 | 5 | 1.0000 | 5 | 1 | 1 | | 199 | 2 | 1.0000 | 2 | 1 | 1 | +-----+-------------+---------+---------+---------+---------+ 10 rows in set (0.00 sec) However when I try to drop it... mysql> DROP TABLE IF EXISTS uc_order_products_qty_vw; Query OK, 0 rows affected, 1 warning (0.00 sec) It doesn't work, the table is still there, and the warning says this... mysql> show warnings limit 1; +-------+------+------------------------------------------+ | Level | Code | Message | +-------+------+------------------------------------------+ | Note | 1051 | Unknown table 'uc_order_products_qty_vw' | +-------+------+------------------------------------------+ 1 row in set (0.00 sec) Feeling pretty dumbfounded.

• Win32 script environment for testing http redirects?

  - by Anders Lindahl

  The past few days I've been working with setting up an Apache server on Windows. The server is supposed to host several .htaccess files, each redirecting (or, in some cases, proxying) to different hosts. I want to create tests for these redirectons, and the solution I'm currently considering is a CGI script running on the same server, sending GET requests to it and verifying that it gets the correct redirection headers back. A scripting solution (vscript/jscript) seems worth exploring, but so far I've only managed to rule out Microsoft.XMLHTTP because it follows the redirect "behind the scenes". Are there any libraries or other solutions already present on a reasonably standard Windows Server that can do this kind of low-level HTTP work? If not, any other suggestions of simple environments to set up for verifying redirects?

• Logging NHibernate SQL queries

  - by GuestMVCAsync

  Is there a way to access the full SQL query, including the values, inside my code? I am able to log SQL queries using log4net: <logger name="NHibernate.SQL" additivity="false"> <level value="ALL"/> <appender-ref ref="NHibernateSQLFileLog"/> </logger> However, I would like to find a way to log SQL queries from the code also. This way I will log the specific SQL query that causes an exception in my try/catch statement. Right now I have to data-mine the SQLFileLog to find the query that caused the exception when an exception occurs and it is not efficient.

• What Visual Studio add-ins do you use for C++ refactoring?

  - by Minyu

  I have just started using Visual Assist X for C++ refactoring in Visual Studio 2008. It is quite good, but IMO, not to the same level as what ReSharper has for C#. I am wondering what people are using for C++ refactoring, especially for larger code base. Here are the add-ins that I have tried so far: * Visual Assist X * Refactor! Pro Meanwhile, does anyone know if Visual Studio 2010 will have any real C++ refactoring tool built in? Many Thanks! Minyu

• Why does this bash command take up all space on device?

  - by chelmertz

  Hey! I'm a little new on searching via bash, so feel free to give me suggestions on the methods to use instead of this, which I'll never use again :) I'm searching for occurances of a string, recursively in a directory, with ~50 not-that-large php-files in it; some in current directory, some in directories beneath current dir, three levels of directories down at most. The method I'm using is: find . | xargs grep "module" > module.txt When in simple (one level) directories, this works fine, but in this case, the file became 4 GB large until it filled up all space on the partition :) It wasn't even done yet.. Would someone educate me so I won't embarass myself again?

• Problem with acceding in DOM with jQuery

  - by Tristan

  Hello, I changed the tree of my JSON-P output, and i cannot access to my object DOM anymore : Here's my output : jsonp1271634374310( {"Inter-Medias": {"name":"Inter-Medias","idGSP":"14","average":"80","services":"8.86"} }); And here's my jQuery script : success: function(data, textStatus, XMLHttpRequest){ widget = data.name; widget += data.average ; .... I know one level is missing, but if I try to do : data.Inter-Medias.name or data.name.name it's still not working. Any idea please ? I will have case where i'll have multiple Ojbect, so i want to display all of them, how to do that ? for (i=0;i < data.length;i++) Does it look right ? Bonus question : i understand function(data, textStatus, XMLHttpRequest) that in case of success this function is triggered, the data is what the script recieved from his request, but i have no idea what textStatus or XMLHttpRequest are here too and why ?! Thank you.

• Best way to correct garbled data caused by false encoding

  - by ercan

  Hi all, I have a set of data that contains garbled text fields because of encoding errors during many import/exports from one database to another. Most of the errors were caused by converting UTF-8 to ISO-8859-1. Strangely enough, the errors are not consistent: the word 'München' appears as 'München' in some place and as 'MÃœnchen'. Is there a trick in SQL server to correct this kind of crap? The first thing that I can think of is to exploit the COLLATE clause, so that ü is interpreted as ü, but I don't exactly know how. If it isn't possible to make it in the DB level, do you know any tool that helps for a bulk correction? (no manual find/replace tool, but a tool that guesses the garbled text somehow and correct them)

• Understanding CGI and SQL security from the ground up

  - by Steve

  This question is for learning purposes. Suppose I am writing a simple SQL admin console using CGI and Python. At http://something.com/admin, this admin console should allow me to modify a SQL database (i.e., create and modify tables, and create and modify records) using an ordinary form. In the least secure case, anybody can access http://something.com/admin and modify the database. You can password protect http://something.com/admin. But once you start using the admin console, information is still transmitted in plain text. So then you use HTTPS to secure the transmitted data. Questions: To describe to a learner, how would you incrementally add security to the least secure environment in order to make it most secure? How would you modify/augment my three (possibly erroneous) steps above? What basic tools in Python make your steps possible? Optional: Now that I understand the process, how do sophisticated libraries and frameworks inherently achieve this level of security?

• Parse Domain from a given URL in T-SQL

  - by Adam N

  I fount this answer, but wanted to expand on the question and couldn't find any solutions here on stack or through searching google. Substring domainname from URL SQL Basically the link above solves my problem with a simple URL like parsing "www.google.com" with the result of google. What I am looking for to expand on that is the solution from the link above doesn't help with url's like 'www.maps.google.com' that just returns maps. WHat I would like is to have it return 'google' from the url 'www.maps.google.com' or return 'example' from 'www.test.example.com'. If anyone has a solution to this, I would greatly appreciate it. Update: To be more specific I will also need parsing on second level domains etc. 'www.maps.google.com.au' to return 'google' Here is my Sql function. CREATE FUNCTION [dbo].[parseURL] (@strURL varchar(1000)) RETURNS varchar(1000) AS BEGIN IF CHARINDEX('.', REPLACE(@strURL, 'www.','')) > 0 SELECT @strURL = LEFT(REPLACE(@strURL, 'www.',''), CHARINDEX('.',REPLACE(@strURL, 'www.',''))-1) Else SELECT @strURL = REPLACE(@strURL, 'www.','') RETURN @strURL END

• How do you boost term relevance in Sql Server Full Text Search like you can in Lucene?

  - by Snives

  I'm doing a typical full text search using containstable using 'ISABOUT(term1,term2,term3)' and although it supports term weighting that's not what I need. I need the ability to boost the relevancy of terms contained in certain portions of text. For example, it is customary for metatags or page title to be weighted differently than body text when searching web pages. Although I'm not dealing with web pages I do seek the same functionality. In Lucene it's called Document Field Level Boosting. How would one natively do this in Sql Server Full Text Search?

• Open Folder within ClearCase Remote Client using Windows Explorer

  - by sammy

  Is there a way to open the folder location of a file from within CCRC? While I know I can open/copy from directly within CCRC, it is often useful to work directly with the file from within Windows Explorer. I am looking for something like "open file location" or "open in windows explorer". The folder within CCRC does not appear to allow opening it directly as the double-mouse-click action just expands the tree listing. The path is listed/copyable within the "ClearCase Details" tab, but I am trying to take my laziness to a whole new level by being able to open the folder with a single click. Any ideas if this is a feature available and where I can find it? Thanks. Info: Rational ClearCase Remote Client 7.1.1 Windows 7

• Bit conversion operations in PHP

  - by Goro

  Hello, I find myself in need of performing bit-level conversion on variables in PHP. In more detail, I have a bit stream that is read as an integer by hardware, and I need to do some operations on the bits to make it into what its actually supposed to be (a float). I have to do this a few times for different formats, and the functionality I need is Being able to select and move individual bits in a variable Being able to cast statically one type of variable to the other (ie. int to float) I know php natively supports bitwise AND, OR, etc, and shift operations, but I was wondering if: there may already be a library in php that does this sort of thing I would be better off with delegating the calculations to some other language Thanks,

• filter log file by defining regexes

  - by fmpdmb

  I have some HUGE log files (50Mb; ~500K lines) I need to start filtering some of the crap out of. The log files are being produced using log4j and have the basic pattern of: [log-level] date-time class etc, etc log-message I'm looking for a way that I can identify a regex start and regex end (or something similar) that will filter out the matching entries from the file so I can more easily wade through these massive files. I'm sure I could write a java program to accomplish this task, but I thought I'd ask the community before going down that path. Thanks in advance.

• How to get the Doctype Declaration in Xerces-C when using SAX2 ?

  - by ArtB

  I am using SAX2 from Xerces-C to read an XML document. However, I would like to check the Doctype declaration (if there is any) to make sure that the XML file is in the format I am expecting. I have tried the unparsedEntityDecl and notationDecl methods from the DTDHandler, and EntityResolver seems to be more low-level than what I am looking for. My motivation is for this is to be able to confirm that the input is of the format I am expecting so that I can differentiate between documents which produce no output and those that are entirely of the wrong format.

• Security for web services only used from a Silverlight application?

  - by Lasse V. Karlsen

  I have googled a bit for how I should handle security in a web service application when the application is basically the data repository for a Silverlight application, but have gotten inconclusive results. The Silverlight application is not supposed to have its own user authentication, since it will be reachable only through a web application that the user have already authenticated to get into. As such, I was thinking I could simply add a parameter to the SL application that is a cookie-type value, with a certain lifetime, linked to the user in the database. The SL application would then have to pass this value alongside other parameters to the web services. Since the web service is hopefully going to be a generic web service endpoint, few methods, adding an extra parameter at this level will not be a problem. But, am I supposed to roll this system on my own? It sounds to me as this isn't exactly new features that nobody has considered before, so what are my options?

• Use Case diagrams as a requirements gathering tool for new functionality - particularly in systems t

  - by drelihan

  Hi Folks I'm interested in persuing the idea of using Use Case Diagrams as a tool for collecting user requirements. However, it will be for new features as opposed to developing a system from scratch. Also, the system only has a small level of user interaction - most of the actors will be external systems. I want to know what people's experiances have been with using this method of gathering requirements. How did your customers respond to the change and was it positive? Did it just not work for anybody? Thanks,

• Accessing cookies in php which are set in java web application

  - by user866937

  I am setting a cookie at the domain level on encrypted connection in Java web application running on tomcat and I would like it to be accessible in a php web application running on a same domain but different subdomain. Java web application running on https://javaapp.mycompany.com php web application running on https://phpapp.mycompany.com/subpath/index.php From java, I am setting the cookie with following parameters: Domain: .mycompany.com Send For: Encrypted connections only Expires: After 2 months Path: /subpath Name: __C Value: 1 Dumping all the cookies from my php web application running on https, I do not see any cookies getting dumped by the php web application. Whereas if I set the cookies in Java for any type of connection, only then php web application is able to see them if I run the php app on http instead of https. I believe php web app should be able to retrieve then cookies set for https only and for particular domain and all immediate sub-domains. What am I doing wrong here? Thanks in advance for the help.

• Why There is a difference between assembly languages like Windows, Linux ?

  - by mcaaltuntas

  I am relatively new to all this low level stuff,assembly language.. and want to learn more detail. Why there is a difference between Linux, Windows Assembly languages? As I understand when I compile a C code Operating system does not really produce pure machine or assembly code, it produces OS dependent binary code.But why ? For example when I use a x86 system, CPU only understands x86 ASM am I right?.So Why we dont write pure x86 assembly code and why there are different assembly variations based on Operating system? If we would write pure ASM or OS produce pure ASM there wouldn't be binary compatilibty issues between Operating systems or Not ? I am really wondering all reasons behind them. Any detailed answer, article, book would be great. Thanks.
