  • Regex to *not* match any characters

    - by Erick
    I know it is quite some weird goal here but for a quick and dirty fix for one of our system we do need to not filter any input and let the corruption go into the system. My current regex for this is "\^.*" The problem with that is that it does not match characters as planned ... but for one match it does work. The string that make it not work is ^@jj (basically anything that has ^ ... ). What would be the best way to not match any characters now ? I was thinking of removing the \  but only doing this will transform the "not" into a "start with" ...

  • Multivalue parametres in SSRS- display in the report

    - by pfeffer
    I just started working with SSRS, so this question might seem silly. Anyway, for now I'm trying to avoid multi-valued parameters, because I want my parameters to be able to be NULL. So I'm just passing a comma-separated string of ID values to my stored procedure, and everything works. The problem I encountered is that I want to display the actual values, not IDs, in the report, so that users can see, what filter was used. If that were a multi-valued parameter, I would simply use JOIN function, but now I am out of ideas and would really appreciate some help. Thanks!

  • Why isn't my IO executed in order?

    - by HaskellElephant
    Hi, I'm having some fun learning about the haskell IO. However in my recent exploration of it I have encountered some problems with IO not executing in order, even inside a do construct. In the following code I am just keeping track of what cards are left, where the card is a tuple of chars (one for suit and one for value) then the user is continously asked for wich cards have been played. I want the putStr to be executed between each input, and not at the very end like it is now. module Main where main = doLoop cards doLoop xs = do putStr $ show xs s <- getChar n <- getChar doLoop $ remove (s,n) xs suits = "SCDH" vals = "A23456789JQK" cards = [(s,n) | s <- suits, n <- vals] type Card = (Char,Char) remove :: Card -> [Card] -> [Card] remove card xs = filter (/= card) xs

  • jQuery: inherit functions to several objects

    - by Fuxi
    hi, i made several table-based-widgets (listview-kind-of) which all have the same characteristics: styling odd/even rows, hover on/off, set color onClick, deleting a row when clicking on trash-icon. so it's always the same (prototype-)code for each widget. is there a way to have the code only once then simply apply/inherit it to all widgets? 2nd, here's some of the code - could this be optimized? var me = this; $("tr",this.table).each(function(i) { var tr = $(this); tr.bind("mouseover",function(){me.hover(tr,true)}); tr.bind("mouseout",function(){me.hover(tr,false)}); tr.bind("click",function(){me.Click(tr)}); }); $("tr").filter(":odd").addClass("odd");

  • Extended maxima transform in Matlab

    - by garvin
    I use imtophat to apply a filter to an m x n array. I then find the local max using imextendedmax(). I get mostly 0's everywhere except for 1's in the general areas where I am expecting a local max. The weird thing is, though, that I don't get just one local max. Instead in these places I get MANY elements with 1's such as 00011100000 00111111000 00000110000 yet the values there are close but NOT equal so I would expect that there would be one that is higher than all of the rest. So I'm wondering a) if this is a bug and how I might fix it and b) how you would choose choose the element of these 1's with the highest value.

  • Force Hibernate To Save A Specific POJO

    - by user1695626
    I have some code calling a webservice and it returns an id. I am saving this id in the database using hibernate. I have a filter that opens the session and commits it, rolling back when any exception occurs within the contained code. Since there is no way to get back the id returned by the webservice I would like to save this in the database EVEN if there is an exception that occurred later on in the code. Is there anyway to do this using the same session?

  • How to add response headers based on Content-type; getting Content-type before the response is commi

    - by Bozho
    I want to set the Expires header for all image/* and text/css. I'm doing this in a Filter. However: before calling chain.doFilter(..) the Content-type is not yet "realized" after calling chain.doFilter(..) the Content-type is set, but so is content-length, which forbids adding new headers (at least in Tomcat implementation) I can use the extensions of the requested resource, but since some of the css files are generated by richfaces by taking them from inside jar-files, the name of the file isn't x.css, but is /xx/yy/zz.xcss/DATB/.... So, is there a way to get the Content-type before the response is committed.

  • Neo4j+Gremlin : Trouble with T.gte and floating point node attributes

    - by letronje
    For a type of nodes in my graph, attribute values for an attribute(named 'some_count') is either missing or an integer or a float. I'm trying to write gremlin to filter these nodes based on minimum value for this attribute. I first verified that the values are indeed present by firing the following gremlin g.v(XXX)._().in('category').hasNot('some_count', T.eq, null).back(1).some_count Next, I tried filtering by exact value and that works and show me the matching nodes or gives an empty array if there is no match g.v(XXX)._().in('category').hasNot('some_count', T.eq, null).back(1).has('some_count', T.eq, 120000.0d) But the following query that uses the 'greater than or equal to' comparator doesn't work. g.v(XXX)._().in('category').hasNot('some_count', T.eq, null).back(1).has('some_count', T.gte, 1.0d) this returns nil (I'm querying via ruby/rails using Neo4j AR Adapter ) Instead of returning an empty array for no match, it returns a nil, which tells me something could be wrong with the query itself. I'm running neo4j community server 1.8. Is there a way I can ask Neo4j to log errors/queries, to see what could be going wrong ?

  • Asp.Net gridview customization

    - by Kunal
    Hi If you go to http://ifdefined.com/btnet/bugs.aspx you will see a long list of sample data in an asp.net gridview control. What I need to do is something similar. I need to implement the filtering system by placing dropdown controls with dynamic values on the headers and then filter the record according to them. If you look carefully they are filtering the data based on multiple drodown selections as well. Kindly help me out. Any kind of input is highly appreciated. Thanks in advance for your time.

  • Prevent Session from being created In some cases

    - by Jean Barmash
    In my app, I have an external monitor that pings the app ever few minutes and measures its uptime / response time Every time the monitor connects, a new server session is created, so when I look at the number of sessions, it's always a minimum of 15, even during times where there are no actual users. I tried to address this with putting the session creation code into a filter, but that doesn't seem to do it - I guess session automatically gets created when the user opens the first page? all() { before = { if (actionName=='signin') { def session = request.session //creates session if not exists } } } I can configure the monitor to pass in a paramter if I need to (i.e. http://servername.com/?nosession, but not sure how to make sure the session isn't created.

  • Linq to Sql query reuse

    - by UserControl
    Let's say we have a view V1 and V2 that is declared like: create view V2 as select V1.*, V2.C1, V2.C2, V2.C3 from V1 join V2 on V1.Key = V2.Key where bla-bla So V2 narrows down the result set of V1 and adds some joins. And there is a retrieval routine in C# IEnumerable<V1> GetData(MyFilter filter, MySortOrder order) {} I want to reuse with V2. Is it possible without performing joins in L2S rather than in database? Should i manually create a base class in the database context or something?

  • Problem loading RTF file into windows richTextBox

    I am trying to load files into a windows (vs 2010) richTextBox but only the first line of the file is loading. I'm using: // Create an OpenFileDialog to request a file to open.

  • Given a document select a relevant snippet.

    - by BCS
    When I ask a question here, the tool tips for the question returned by the auto search given the first little bit of the question, but a decent percentage of them don't give any text that is any more useful for understanding the question than the title. Does anyone have an idea about how to make a filter to trim out useless bits of a question? My first idea is to trim any leading sentences that contain only words in some list (for instance, stop words, plus words from the title, plus words from the SO corpus that have very weak correlation with tags, that is that are equally likely to occur in any question regardless of it's tags)

  • Is angularjs capable of filtering based on keywords?

    - by Alex90
    I have 30 categories in mysql. I have 450 subcategories which are related to the 30 categories in another table. Categories table id _ title _ Keywords 1 _ Animals _ animal, animals, pet, parrot 2 _ Books _ books, book, educational n _ xxx _ xxx Subcategories table id _ ref _ title _ keywords 1 _ 1 _ cats _ cats, persian cat, bengal cat 2 _ 1 _ dogs _ dogs, labrador, golder retriver 3 _ 2 _ Classic _ The davinci code, books, book, classical books I need to implement the filter to a textfield. If the users enters labrador in the textfield then show the categories or/and subcategories which contain 'labrador' in the keywords. In this case the "dogs" subcategory would appear! I know that this has been done using jquery. But is there anyway to implement this with angularJs? If you got a jsfiddle then it would be awesome! :) Thank you

  • [app-engine-java-groovy] One-to-Many relationship. Select objects from datastore.

    - by Olexandr
    Hi. I've omitted some code(package declarations, imports, other fields) for shortness. I have here simple One-to-Many relation. It worked fine till this moment. @PersistenceCapable(identityType = IdentityType.APPLICATION, detachable="true") class Restaurant implements Serializable { @PrimaryKey @Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY) Key id @Persistent(mappedBy = "restaurant") List<RestaurantAddress> addresses = new ArrayList<RestaurantAddress>() } //-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= @PersistenceCapable(identityType = IdentityType.APPLICATION, detachable="true") class RestaurantAddress implements Serializable { @PrimaryKey @Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY) Key id @Persistent Restaurant restaurant } Now i need to get(select) all the Restaurants from DB: def getRestaurantsToExport(final String dst, final int count) { String field = restaurantExportFields[dst] return transactionExecute() { PersistenceManager pm -> Query q = pm.newQuery(Restaurant.class) q.filter = "$field == null" q.setRange(0, count) return q.execute() } } But there are on problem - query gives me 12 restaurants(as in DB) but every Restaurant has 0 Address but in Datastore every Restaurant has minimum 2 addresses. Have anyone the same problem or knows the solution ?

  • Is there an Objective-C algorithm like `transform` of the C++ STL?

    - by pesche
    My goal is to have an array that contains all filenames of a specific extension, but without the extension. There's an elegant solution to get all filenames of a specific extension using a predicate filter and instructions on how to split a path into filename and extension, but to combine them I would have to write a loop (not terrible, but not elegant either). Is there a way with Objective-C (may be similar to the predicate mechanism) to apply some function to every element of an array and put the results in a second array, like the transform algorithm of the C++ STL does?

  • How do I prevent a pair of XMLEvent[Reader|Writer] from splitting empty tags into start+end tags?

    - by java.is.for.desktop
    Hello, everyone! I have an understanding problem of how the following code works: XMLInputFactory xif = XMLInputFactory.newFactory(); XMLOutputFactory xof = XMLOutputFactory.newFactory(); XMLEventReader reader = xif.createXMLEventReader(/* ... */); XMLEventWriter writer = xof.createXMLEventWriter(/* ... */); writer.add(reader); The method writer.add([some reader]) reads all events from reader and writes them consequently. Sadly, following happens: The input <root><c/></root> gets transformed to <root><c><c/></root> I know, from XML point of view, these are equal trees, but not for a human ;) What can I do to get the same output? FYI: I need a XMLEvent[Reader|Writer] pair later to filter "XML events".

  • Occasional conversion error using SUM function

    - by user153777
    My app uses sql2000 and a select statement it uses will sometimes fail. Once a week or so the select returns the error 'Error Converting data type varchar to numeric' SQL: sum(case when ISNULL(form_prsn_id, -1) = irpd_prsn_id then convert(dec(11,2), case when valu_value = '' then '0' else isnull (valu_value,'0') end)* case when fmdt_deduction_flag = 'Y' then -1 else 1 end else 0 end) as client_sum The valu_value field is a varchar and stores some numeric and some varchar. But including my join and where clause filter it will always select numeric or empty string. When it is failing I can remove the SUM, see the data and know that its numeric. So why would the SUM function sometimes (say 5% of time) fail on data that is numeric. I wonder if SQL somehow "looks ahead" to ensure it could convert to decimal on more than just the rows returned without the sum. Note I have discovered a fix where I include ( where isNumeric(valu_value) = 1 ) Thanks

  • stepping into a linq query

    - by MyNameIsJob
    Is it possible to step into a linq query? I have a linq to entity framework 4 query in it's simplest form: List = List.Where(f => f.Value.ToString().ToLowerInvariant().Contains(filter.ToLowerInvariant())); It's a query against an Entity Framework DbContext and I'm having trouble seeing why it works for something like: List searching for 001 yields no results against the following list Test001 Test002 Test003 Test004 However any other search yields results (Such as t00 or Test) I was hoping to figure out a way to see the resulting sql but it appears that I need Intellitrace, which I don't currently have or possibly stepping through the query itself and see each iteration build itself.
