• Drupal Views Duplicate values being returned when using a relationship

  - by Linda

  I am having a problem with views. I have a view and am passing it a taxonomy term by name to it. I then have a relationship to a related node. For my output fields I am returning the related Title and related Body. I however have duplicates in my results. I have turned distinct to yes but believe this is working on the nodes being return and not the related node. Any ideas how I can remove the duplicates? Update Below is the query being run when I only get the title SELECT DISTINCT(node.nid) AS nid, node_node_data_field_wine_company.title AS node_node_data_field_wine_company_title, node_node_data_field_wine_company.nid AS node_node_data_field_wine_company_nid FROM node node LEFT JOIN content_type_wine node_data_field_wine_company ON node.vid = node_data_field_wine_company.vid INNER JOIN node node_node_data_field_wine_company ON node_data_field_wine_company.field_wine_company_nid = node_node_data_field_wine_company.nid LEFT JOIN term_node term_node ON node.vid = term_node.vid INNER JOIN term_data term_data ON term_node.tid = term_data.tid WHERE term_data.name = 'test' GROUP BY nid It looks like I should be grouping by node_node_data_field_wine_company_nid or selecting distinct values from there. Any ideas?

• How can I mark a group of changes/changesets in SVN, Hg, or Git

  - by sylvanaar

  I would like to mark an arbitrary group of commits/changesets with a label. Commit 1 *Mark 1 Commit 2 *Mark 2 Commit 3 Commit 4 *Mark 1 Commit 5 *Mark 2 The goal is to easily locate all the changes for a specific mark, and to have that grouping persisted in the VCS directly, as opposed to some outside system like a bug tracking system. The location and ordering of the marks needs to be arbitrary, and should be able to work with both committed/uncommitted and pushed/unpushed changes. In SVN the best way I know is to just edit the commit notes and add some sort of special text that you can search for e.g. "**Mark 1". Or just to make a fake edit and commit it and use its commit note to list all the included revisions. Is there a better solution for SVN? Are there equivalent or better solutions for Hg or Git?

• Nhibernate Criteria Group By clause and select other data that is not grouped

  - by Peter R

  Hi, I have a parent child relationship, let's say class and children. Each child belongs to a class and has a grade. I need to select the children (or the ids of the children) with the lowest grade per class. session.CreateCriteria(typeof(Classs)) .CreateAlias("Children", "children") .SetProjection(Projections.ProjectionList() .Add(Projections.Min("children.Grade")) .Add(Projections.GroupProperty("Id")) ) .List<Object[]>(); This query returns me the lowest grade per class, but I don't know which child got the grade. When I add the children's Id to the group, the group is wrong and every child gets returned. I was hoping we could just select get the id's of those childs without grouping them. If this is not possible, then maybe there is a way to solve this with subqueries?

• ASP.NET MVC Validation - localisation of the error string

  - by gmang

  I followed the techique ASP.NET MVC 2: Model Validation from Scott Gu. (http://weblogs.asp.net/scottgu/archive/2010/01/15/asp-net-mvc-2-model-validation.aspx). However I am building a localised web site. How can I localized the error string? I tried the following by replacing the following: [RegularExpression(@"\d{4}",ErrorMessage="Must be a 4 digit year")] public Nullable YearOfWork { get; set; } With the following: [RegularExpression(@"\d{4}",ErrorMessage=Resources.SharedStrings.search_error1)] public Nullable YearOfWork { get; set; } but I get a complilation error: An attribute argument must be a constant expression, typeof expression or array creation expression of an attribute parameter type Please help!

• T-SQL IsNumeric() and Linq-to-SQL

  - by cdonner

  I need to find the highest value from the database that satisfies a certain formatting convention. Specifically, I would like to fund the highest value that looks like EU999999 ('9' being any digit) select max(col) will return something like 'EUZ...' for instance that I want to exclude. The following query does the trick, but I can't produce this via Linq-to-SQL. There seems to be no translation for the isnumeric() function in SQL Server. select max(col) from table where col like 'EU%' and 1=isnumeric(replace(col, 'EU', '')) Writing a database function, stored procedure, or anything else of that nature is far down the list of my preferred solutions, because this table is central to my app and I cannot easily replace the table object with something else. What's the next-best solution?

• Print "1 followed by googolplex number of zeros" [closed]

  - by Rajan

  Assuming we are not concerned about running time of the program (which is practically infinite for human mortals), we want to print out in base 10, the exact value of 10^(googolplex), one digit at a time (mostly zeros). Describe an algorithm (which can be coded on current day computers), or write a program to do this. Since we cannot practically check the output, so we will rely on collective opinion on the correctness of the program. NOTE : I do not know the solution, or whether a solution exists or not. The problem is my own invention. To those readers who think this is not a CS question... kindly reconsider. This is difficult and bit theoretical but definitely CS.

• all rows plus min / max values using a single stored procedure

  - by Rajeev

  I have a custom data source which pulls out data form a flat file. The flat file contains a timestamp , source and data. I can use sp_execute to execute a select query against the flat file. I'm currently using 2 stored procedures . - one which runs a select * from flat_file into a temp table - the other which does a select min/max from flat_file grouping by source into another temp file Im using the data retrieved using the stored procedures in a SSRS report Is is possible in a a single stored procedure to retrieve all the rows from the file within a date range and also identify the min/max values for each group retrieved ?e

• Custom filename in a rolling Log4Net logfile?

  - by Brett Rigby

  Hello We have a ASP .Net application whereby we use Log4Net to log details within the app - nothing new there - and the rolling log filenames are in the usual format of: rolling-log.txt rolling-log.txt.1 rolling-log.txt.2 etc. A each user of the application adds to the logfile, the logfile can be difficult to read for a specific user's case and so, we'd like to modify the config file somehow to record the user's log details individually, each writing to a specific file, e.g. <applicationId>rolling-log.txt <applicationId>rolling-log.txt.1 <applicationId>rolling-log.txt.2 etc. where is each user's unique application Id, made up of a five digit number, e.g. 12345rolling-log.txt Any ideas on the best way to implement this, assuming that it's possible? Cheers Brett

• DateTime: Require the user to enter a time component

  - by Heinzi

  Checking if a user input is a valid date or a valid "date + time" is easy: .NET provides DateTime.TryParse (and, in addition, VB.NET provides IsDate). Now, I want to check if the user entered a date including a time component. So, when using a German locale, 31.12.2010 00:00 should be OK, but 31.12.2010 shouldn't. I know I could use DateTime.TryParseExact like this: Dim formats() As String = {"d.M.yyyy H:mm:ss", "dd.M.yyyy H:mm:ss", _ "d.MM.yyyy H:mm:ss", "d.MM.yyyy H:mm:ss", _ "d.M.yyyy H:mm", ...} Dim result = DateTime.TryParseExact(userInput, formats, _ Globalization.CultureInfo.CurrentCulture, ..., result) but then I would hard-code the German format of specifying dates (day dot month dot year), which is considered bad practice and will make trouble should we ever want to localize our application. In addition, formats would be quite a large list of all possible combinations (one digit, two digits, ...). Is there a more elegant solution?

• Databinding int32 to MaskedEditExtender enabled TextBox

  - by Zach Skinner

  I have a master/detail scheme for editing an asp:GridView using an asp:DetailsView. One of my fields is for a phone number of type int64 (always 10 digits). I would like this field to always be displayed as (###)###-####. My issue is the first digit in the phone number is always truncated for my edit item field which I used a MaskedEditExtender to achieve the formatting. Here is my EditItemTemplate for the details view: <cc1:MaskedEditExtender TargetControlID="edtPROJ_Leader_Phone" Mask="(999)999-9999" runat="server" ClearMaskOnLostFocus="false" ClipboardEnabled="true" MaskType="Number" /> <asp:TextBox ID="edtPROJ_Leader_Phone" runat="server" Text='<%# Bind("PROJ_Leader_Phone") %>' ></asp:TextBox> When my details view is displayed for editing, the text box displays(_23)456-7890 for the integer 1234567890. Also worth noting that if the property MaskType="Number" is removed, the textbox shows: (234)567-890_. I would of course have the textbox show (123)-546-67890 after binding.

• Project Euler 79: what am I missing?

  - by Evert

  Hi Guys, I'm not interested in the answer, but I need to be pointed in the right direction Here's problem 79 I first try to analyze the file myself. I've noticed that the number 7 only ever appears as the first digit. This immediately implies that all the numbers containing 7 never overlaps with under numbers (on the left side). Since the questions in project euler always have 1 answer, I believe I'm misunderstanding the question. Do I not have to use all numbers? If I do have to use all numbers, there's many different possible numbers. Where am I going wrong?

• Decoding a compressed short string; uncertain on compression used - Updated

  - by James

  Hi, I have a program that is compressing a string in an unknown way. I know a few inputs and the output produced, but I am not sure what is being used to compress the string. Here are my examples. (just 38 x a, no spaces or anything else) In: "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa" Out: "026900211AA63000026900"   (just 32 x a) In: "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa" Out: "0209001c1aa7a000020900" (31 x a, then 1 b) In: "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaab" Out: "0209000177c553c000020900" (31 x b, then 1 a) In: "bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbba" Out: "0209001e7754f38000020900" In: "Hey wot u doing 2day u wanna do something" Out: "02990011C7C62E78CE6B8E3ACD83E81B37C5C5A6B9D1E1B06963DB5E71155C1000029900" (same as previous string, but with a space at the end) In: "Hey wot u doing 2day u wanna do something " Out: "02A90012C7718B9E339AE2EB360FA02CDF17177A674786DF4B1EDAF388AAE08000000002A90000" The only definite thing I can see so far is digit 2 and 3 are the amount of characters (hex value), ie first one is 26 = 38 Also the first 6 digits are repeated at the end Any help / advice would be great, thanks!

• Junit vs TestNG

  - by Sam Merrell

  At work we are currently still using Junit3 to run our tests. We have been considering switching over to Junit4 for new tests being written but I have been keeping an eye on TestNG for a while now. What experiences have you all had with either Junit4 or TestNG and which seems to work better for very large numbers of tests. Having flexibility in writing tests is also important to us since our functional tests cover a wide aspect and need to be written in a variety of ways to get results. Old tests will not be re-written as they do their job just fine. What I would like to see in new tests though is flexibility in the way the test can be written, natural assertions, grouping, and easily distributed test executions.

• Significant figures in the decimal module

  - by Jason Baker

  So I've decided to try to solve my physics homework by writing some python scripts to solve problems for me. One problem that I'm running into is that significant figures don't always seem to come out properly. For example this handles significant figures properly: from decimal import Decimal >>> Decimal('1.0') + Decimal('2.0') Decimal("3.0") But this doesn't: >>> Decimal('1.00') / Decimal('3.00') Decimal("0.3333333333333333333333333333") So two questions: Am I right that this isn't the expected amount of significant digits, or do I need to brush up on significant digit math? Is there any way to do this without having to set the decimal precision manually? Granted, I'm sure I can use numpy to do this, but I just want to know if there's a way to do this with the decimal module out of curiosity.

• Gridview with row headers

  - by Seagull

  I am using the ASP.NET3.5 gridview control in a new project. My problem is that the gridview presents data in basic tabular format, whereas I want a grid with row header / grouping behaviors. An example of this would be Outlook web interface, which can group emails by date, as well as allowing you to select individual emails to display. My problem: I can't see how this could be easily done with Gridview? I did find a product called Telerik that has a seemingly fancy Gridview, but I am hesitant to spend money on a single components that now also locks me into a third-party framework...

• Css editor with certain features

  - by user255408

  I need a light css editor with certain functions. Already downloaded and tried a few apps but still no luck, none of them fit my requirements. Actually, there is one, CssEdit (or TextMate), but unfortunately i'm a windows user... Already tried: built-in NetBeans IDE css editor (btw nice editor, the one i'm using now for css) IntelJ IDE (very good html and css editor, but using the entire ide just for this - that's crazy) ArduoCss (very buggy in win7 environment) Notepad Notepad++ (it rules, but as i said, i need something more functional for css editing) Style Master ( if i don't find anything else, probably i'll choose this one) Stylizer ( also might be my choice, but it's black interface kills me, also extremy noob-oriented, i even couldn't find a way to see the source code) Some of the features i am looking for: grouping by comments like here snippets autocomplete, if i type for instance f-s, it should recognize and expand it to "font-size" property color picker The editor must have at least the first feature that i listed above. Sorry for my poor english.

• CSS selector for grouped iterations

  - by snaken

  Hi, I have a number of elements that i want to loop through as groups. Consider this HTML: <input class="matching match-1" /> <input class="matching match-1" /> <input class="matching match-2" /> <input class="matching match-2" /> <input class="matching match-2" /> <input class="matching match-3" /> <input class="matching match-3" /> // etc I want a CSS selector that would allow me to loop through these as groups so there would be - using this example - 3 iterations of the loop (one for match-1, one for match-2 and one for match-3). The 1,2,3 etc is a variable used for grouping but this is not fixed so it cannot rely on hard coding of these values. Is this even possible? I'll be using jQuery or prototype not that that should matter really. Thanks

• Situations to prefer Apache Lucene over Solr?

  - by Karussell

  There are several advantages to use Solr (out-of-the-box facetting search, grouping, replication, http administration vs. luke, ...). Even if I embed a search-functionality in my Java application I could use SolrJ to avoid the HTTP trade-off when using Solr. So, when would you recommend to use "pure-Lucene"? Does it have a better performance or requires less RAM? Is it better unit-testable? PS: I am aware of this question.

• Rails ActiveRecord BigNum to JSON

  - by Jon Hoffman

  Hi, I am serializing an ActiveRecord model in rails 2.3.2 to_json and have noticed that BigNum values are serialized to JSON without quotes, however, javascript uses 64 bits to represent large numbers and only ~52(?) of those bits are available for the integer part, the rest are for the exponent. So my 17 digit numbers become rounded off, grrr. Try the following in the Firebug console: console.log(123456789012345678) So, I'm thinking that the json encoder should be smart enough to quote numbers that are too big for the javascript engines to handle. How do I fix up rails to do that? Or, is there a way to override the encoding for a single property on the model (I don't want to_s elsewhere)? Thanks.

• Where to get MSDN Help Viewer for 2010 like earlier MSDN with Index, Tree and one window?

  - by Akash Kava

  I upgraded to Visual Studio 2010 RC, and I remember filling one big form for MSDN help improvement campaign and I was wondering I will get to see a Help Viewer like MSDN included in Visual Studio 2008, which included One Program (Not IE), Index and the way to view preferred language setting. Google results shows that there were headlines that Microsoft Help Viewer released for 2010 RC, but where is it? is it the same one which opens in IE and has absolute difficult way to view it? Current MSDN opening in IE is so inconvenient, there is no index, there is no grouping of content, like I typed search for TextBox and it showed up for ASP.NET, WinForms and I got lost to find out the reference in multiple pages for search results.

• Algorithm - Numbering for TOC (Table of Contents)

  - by belisarius

  I want to implement a VBA function to number Excel rows based upon the grouping depth of the row. But I think a general algorithm for generating TOCs is more interesting. The problem is: Given a list of "indented" lines such as One Two Three Four Five Six (the "indentation level" may be assumed to be known and part of the input data) To generate the following output: 1. One 1.1 Two 1.1.1 Three 1.1.1.1 Four 1.2 Five 2. Six Of course my code is up and running ... and also hidden under THWoS (The Heavy Weight of Shame)

• Regex question: Why isn't this matching?

  - by AllenG

  I have the following regex: (?<=\.\d+?)0+(?=\D|$) I'm running it against a string which contains the following: SVC~NU^0270~313.3~329.18~~10~~6.00: When it runs, it matches the 6.00 (correctly) which my logic then trims by one zero to turn into 6.0. The regex then runs again (or should) but fails to pick up the 6.0. I'm by no means an expert on Regex, but my understanding of my expression is that it's looking for a decimal with 1 or more optional (so, really zero or more) digits prior to one or more zeros which are then followed by any non-digit character or the line break. Assuming that interpretation is correct, I can't see why it wouldn't match on the second pass. For that matter, I'm not sure why my Regex.Replace isn't matching the full 6.00 on the first pass and removing both of the trailing zeros... Any suggestions?

• Union of complex polygons

Dave's example uses SQL server to produce the union, but I need to accomplish the same in code. I'm looking for a mathematical formula or code example in any language that exposes the actual math. I am attempting to produce maps that combine countries dynamically into regions. I asked a related question here: http://stackoverflow.com/questions/2653812/grouping-geographical-shapes

• Should I replace string patterns in asp.net mvc using a custom viewengine?

  - by Roger Rogers

  Have an ASP.NET MVC site that is localized. The localization functionality adds the two digit language ID to the URL, e.g. /es/Page. If no language Id is found in the URL, the site switches to the user's browser culture. All's good. However, the site's hyperlinks, a mixture of hard-coded href tags, actionlinks, etc., don't include the base language ID, so when clicking through the site the set culture is lost, and the site reverts to the user's browser culture. My (lazy) thought is to replace all href values, that don't point to an external site, with the localized URL (e.g. include the /es/). Otherwise, all site links will need to be updated to include the culture code. Is this just plain dumb? Or, reasonable, and should be done using a custom view engine, or some other approach?
