  • Order by null/not null with ICriteria

    - by Kristoffer
    I'd like to sort my result like this: First I want all rows/objects where a column/property is not null, then all where the colmn/property is null. Then I want to sort by another column/property. How can I do this with ICriteria? Do I have to create my own Order class, or can it be done with existing code? ICriteria criteria = Session.CreateCriteria<MyClass>() .AddOrder(Order.Desc("NullableProperty")) // What do I do here? IProjection? Custom Order class? .AddOrder(Order.Asc("OtherProperty"));

  • Help with boost::lambda expression

    - by Venkat Shivanandan
    I tried to write a function that calculates a hamming distance between two codewords using the boost lambda library. I have the following code: #include <iostream> #include <numeric> #include <boost/function.hpp> #include <boost/lambda/lambda.hpp> #include <boost/lambda/if.hpp> #include <boost/bind.hpp> #include <boost/array.hpp> template<typename Container> int hammingDistance(Container & a, Container & b) { return std::inner_product( a.begin(), a.end(), b.begin(), (_1 + _2), boost::lambda::if_then_else_return(_1 != _2, 1, 0) ); } int main() { boost::array<int, 3> a = {1, 0, 1}, b = {0, 1, 1}; std::cout << hammingDistance(a, b) << std::endl; } And the error I am getting is: HammingDistance.cpp: In function ‘int hammingDistance(Container&, Container&)’: HammingDistance.cpp:15: error: no match for ‘operator+’ in ‘<unnamed>::_1 + <unnamed>::_2’ HammingDistance.cpp:17: error: no match for ‘operator!=’ in ‘<unnamed>::_1 != <unnamed>::_2’ /usr/include/c++/4.3/boost/function/function_base.hpp:757: note: candidates are: bool boost::operator!=(boost::detail::function::useless_clear_type*, const boost::function_base&) /usr/include/c++/4.3/boost/function/function_base.hpp:745: note: bool boost::operator!=(const boost::function_base&, boost::detail::function::useless_clear_type*) This is the first time I am playing with boost lambda. Please tell me where I am going wrong. Thanks.

  • group expression in jasper reports

    - by ed1t
    I've a report which has a has 5 columns on each page and I have a group defined which shows columns related to A | B | C | D | E - main column X | Y | Z - group - A is the key I have my query ORDER BY A, but when it is displayed it doesn't print the results in next page if A is changed. Following is how I have a group defined. <group name="A" isResetPageNumber="true" > <groupExpression><![CDATA[$F{A}]]></groupExpression> <groupHeader> <band/> </groupHeader> <groupFooter> <band/> </groupFooter> </group> does A need to be part of the group?

  • Rewriting An URL With Regular Expression Substitution in Routes

    - by Sean M
    In my Pylons app, some content is located at URLs that look like http://mysite/data/31415. Users can go to that URL directly, or search for "31415" via the search page. My constraints, however, mean that http://mysite/data/000031415 should go to the same page as the above, as should searches for "0000000000031415." Can I strip leading zeroes from that string in Routes itself, or do I need to do that substitution in the controller file? If it's possible to do it in routing.py, I'd rather do it there - but I can't quite figure it out from the documentation that I'm reading.

  • Verifying regular expression for malware removal

    - by Legend
    Unfortunately, one of my web servers was compromised recently. I have two questions. Is there a way I can scan the downloaded directory for backdoors? Is there anything I can do to ensure that at least known vulnerabilities do not exist anymore? Secondly, the malware put up the following in all index.* files on my webserver: <script>/*GNU GPL*/ try{window.onload = function(){var Hva23p3hnyirlpv7 = document.createElement('script');Hva23p3hnyirlpv7.setAttribute('type', 'text/javascript');Hva23p3hnyirlpv7.setAttribute('id', 'myscript1');Hva23p3hnyirlpv7.setAttribute('src',.... CODE DELETED FOR SAFETY.... );}} catch(e) {}</script> Obviously, this snippet seems to download some rogue file onto the user's machine. I downloaded an entire backup of the web server and am currently trying to remove this snippet from all file. For this I am doing: find ./ -name "index.*" -exec sed -i 's/<script>\/\*GNU GPL\*.*Hva23p3hnyirlpv7.*<\/script>//g' {} \; Just wanted to verify if this does the trick. I verified it with a few files but I want to be sure that this doesn't delete some valid code. Anyone suggests any other modifications?

  • Fine tune some SQL called multiple times

    - by Carl
    Hi all, I currently have an SQL query which is currently called multiple times like this (pseudo code): foreach(KeyValuePair kvp in someMapList) { select col1 from table where col2 = kvp.key and col3 = kvp.value; //do some processing on the returned value } The above could obviously call the database a large number of times if it is a big list of pairs. Can anyone think of a more efficient piece of SQL which could essentially return a list of specific values based on a list of two unique pieces of information so that the processing can be done in bulk? One obvious one would be to build up a big piece of SQL with ORs but this would probably be quite inefficient? Thanks Carl

  • XPath expression for a phpBB forum

    - by Biff
    I'm writing a Greasemonkey script, and I wanted to change the text of a forum post on a phpBB2 forum by using XPath to select the body of the post that occurs after a certain username, but the whole thing is a giant mess of tables. <tr> <td> <span class="name"> <a> <b>username</b> </span> <span></span> </td> <td> <table> <tbody> <tr></tr> <tr></tr> <tr> <td> <span class="postbody">text of post</span> <span></span> </td> </tr> </tbody> </table> </td> </tr> I need to get the postbody span that happens after the username in the b tag equals a certain name, and then mess with the text.

  • Python regular expression implementation details

    - by Tom
    A question that I answered got me wondering: How are regular expressions implemented in Python? What sort of efficiency guarantees are there? Is the implementation "standard", or is it subject to change? I thought that regular expressions would be implemented as DFAs, and therefore were very efficient (requiring at most one scan of the input string). Laurence Gonsalves raised an interesting point that not all Python regular expressions are regular. (His example is r"(a+)b\1", which matches some number of a's, a b, and then the same number of a's as before). This clearly cannot be implemented with a DFA. So, to reiterate: what are the implementation details and guarantees of Python regular expressions? It would also be nice if someone could give some sort of explanation (in light of the implementation) as to why the regular expressions "cat|catdog" and "catdog|cat" lead to different search results in the string "catdog", as mentioned in the question that I referenced before.

  • Regular Expression Fill-Down

    - by richardtallent
    I have a plain text file something like this: Ford\tTaurus F-150 F-250 Toyota\tCamry Corsica In other words, a two-level hierarchy where the first child is on the same line as the parent, but subsequent children on lines following, distinguished from being a parent by a two-space prefix (\t above represents a literal tab in the text). I need to convert to this using RegEx: Ford\tTaurus Ford\tF-150 Ford\tF-250 Toyota\tCamry Toyota\tCorsica So, I need to capture the parent (text between \r\n and \t not starting with \s\s), and apply that in the middle of any \r\n\s\s found until the next parent. I have a feeling this can be done with some sort of nested groups, but I think I need more caffeine or something, can't seem to work out the pattern. (Using .NET with IgnoreWhitespace off and Multiline off)

  • ISQLQuery using AddJoin not loading related instance

    - by Remi Despres-Smyth
    I've got a problem using an ISQLQuery with an AddJoin. The entity I'm trying to return is RegionalFees, which has a composite-id which includes a Province instance. (This is the the instance being improperly loaded.) Here's the mapping: <class name="Project.RegionalFees, Project" table="tblRegionalFees"> <composite-id name="Id" class="Project.RegionalFeesId, project" unsaved-value="any" access="property"> <key-many-to-one class="Project.Province, Project" name="Region" access="property" column="provinceId" not-found="exception" /> <key-property name="StartDate" access="property" column="startDate" type="DateTime" /> </composite-id> <property name="SomeFee" column="someFee" type="Decimal" /> <property name="SomeOtherFee" column="someOtherFee" type="Decimal" /> <!-- Other unrelated stuff --> </class> <class name="Project.Province, Project" table="trefProvince" mutable="false"> <id name="Id" column="provinceId" type="Int64" unsaved-value="0"> <generator class="identity" /> </id> <property name="Code" column="code" access="nosetter.pascalcase-m-underscore" /> <property name="Label" column="label" access="nosetter.pascalcase-m-underscore" /> </class> Here's my query method: public IEnumerable<RegionalFees> GetRegionalFees() { // Using an ISQLQuery cause there doesn't appear to be an equivalent of // the SQL HAVING clause, which would be optimal for loading this set const String qryStr = "SELECT * " + "FROM tblRegionalFees INNER JOIN trefProvince " + "ON tblRegionalFees.provinceId=trefProvince.provinceId " + "WHERE EXISTS ( " + "SELECT provinceId, MAX(startDate) AS MostRecentFeesDate " + "FROM tblRegionalFees InnerRF " + "WHERE tblRegionalFees.provinceId=InnerRF.provinceId " + "AND startDate <= ? " + "GROUP BY provinceId " + "HAVING tblRegionalFees.startDate=MAX(startDate))"; var qry = NHibernateSessionManager.Instance.GetSession().CreateSQLQuery(qryStr); qry.SetDateTime(0, DateTime.Now); qry.AddEntity("RegFees", typeof(RegionalFees)); qry.AddJoin("Region", "RegFees.Id.Region"); return qry.List<RegionalFees>(); } The odd behavior here is that when I call GetRegionalFees (whose goal is to load just the most recent fee instances per region), it all loads fine if the Province instance is a proxy. If, however, Province is not loaded as a transparent proxy, the Province instance which is part of RegionalFees' RegionalFeesId property has null Code and Region values, although the Id value is set correctly. It looks to me like I have a problem in how I'm joining the Province class - since if it's lazy loaded the id is set from tblRegionalFees, and it gets loaded independently afterwards - but I haven't been able to figure out the solution.

  • An item with the same key has already been added.

    Can someone advice me how to prevent this error. An item with the same key has already been added.? // Failed to find a matching SessionFactory so make a new one. if (sessionFactory == null) { Check.Require(File.Exists(sessionFactoryConfigPath), "The config file at '" + sessionFactoryConfigPath + "' could not be found"); Configuration cfg = new Configuration(); cfg.Configure(sessionFactoryConfigPath); /*MINE*/ var persistenceModel = new PersistenceModel(); persistenceModel.AddMappingsFromAssembly(Assembly.Load("EMedicine.Core")); persistenceModel.Configure(cfg); /*END_OF_MINE*/ // Now that we have our Configuration object, create a new SessionFactory sessionFactory = cfg.BuildSessionFactory(); if (sessionFactory == null) { throw new InvalidOperationException("cfg.BuildSessionFactory() returned null."); } if (sessionFactoryConfigPath != null) sessionFactories.Add(sessionFactoryConfigPath, sessionFactory); } Error is here: sessionFactory = cfg.BuildSessionFactory();

  • Spring HibernateTemplate: how it deals with transactions?

    - by EugeneP
    Could you explain, what happens behind the scene? Transaction management when using this template in Spring is absolutely unclear. What if I invoke 10 DAO methods that all use the same Hibernatetemplate and I invoke them one after another? Every method runs within its own transaction? It's not effective is not it?

  • Having trouble with Regular Expression and Ampersand

    - by ajax81
    Hi All, I'm having a bit of trouble with regex's (C#, ASP.NET), and I'm pretty sure I'm doing something fundamentally wrong. My task is to bind a dynamically created gridview to a datasource, and then iterate through a column in the grid, looking for the string "A&I". An example of what the data in the cell (in template column) looks like is: Name: John Doe Phone: 555-123-1234 Email: [email protected] Dept: DHS-A&I-MRB Here's the code I'm using to find the string value: foreach(GridViewRow gvrow in gv.Rows) { Match m = Regex.Match(gvrow.Cells[6].Text,"A&I"); if(m.Success) { gvrow.ForeColor = System.Drawing.Color.Red; } } I'm not having any luck with any of these variations: "A&I" "[A][&][I]" But when I strictly user "&", the row does turn red. Any suggestions? Thanks, Dan

  • Castle ActiveRecord optimistic locking on properties

    - by Daniel T.
    Can Castle ActiveRecord do optimistic locking on properties? I found optimistic locking for the entire class, but not for an individual property. In my case, I need to make it so that adding/removing elements in a collection does not update the version number of the entity (so for example, adding a Product to a Store without changing any of Store's properties will not increment the version number).

  • How to match filetype with regular expression?

    - by Sanarothe
    Hi. I'm stuck trying to get a regex to match a filetype in a sorting script. Dir.foreach(savedirs[0]) do |x| puts "Matching " + x + " against filetypes." case x when x.match(/^.*\.exe$/i) then puts x when x.match(/\.jpe?g$/) then FileUtils.move(x, sortpath[".exe"], :verbose => true) when x =~ /\.jpg$/ then FileUtils.move(x, sortpath[".jpg"]) end end I can't get any of these to match on in windows. All I need is to confirm that a given filename matches against compatible filetypes.

I have a ListBox in Class1 view which displays Class2. How to map the output of the ListBox back to IList Class2s property of Class1? I am able to display the values in the ListBox but unable to map back the SelectListItem to IList.
