• Passing values across pages ASP.net

  - by GigaPr

  Hi i need to pass a long list of Ids from one page to another, i was thinking of using querystring but taking in consideration that the number of ids to be passed may reach 300 i think is not a good idea. an option from my understanding may be the use of session, this seems to me an optimal solution in my case but on the other hand I can certainly clear the session when the user performs a certain action and the list of ids is not longer needed, but if the user leaves the page without performing any action i want to clear the session, how can i do it? If multiple users are using the same functionality do i need the session's items to be confused or the session is for a single user? I am working in asp.net c# Thanks

• How to do query auto-completion/suggestions in Lucene?

  - by Mat Mannion

  I'm looking for a way to do query auto-completion/suggestions in Lucene. I've Googled around a bit and played around a bit, but all of the examples I've seen seem to be setting up filters in Solr. We don't use Solr and aren't planning to move to using Solr in the near future, and Solr is obviously just wrapping around Lucene anyway, so I imagine there must be a way to do it! I've looked into using EdgeNGramFilter, and I realise that I'd have to run the filter on the index fields and get the tokens out and then compare them against the inputted Query... I'm just struggling to make the connection between the two into a bit of code, so help is much appreciated! To be clear on what I'm looking for (I realised I wasn't being overly clear, sorry) - I'm looking for a solution where when searching for a term, it'd return a list of suggested queries. When typing 'inter' into the search field, it'll come back with a list of suggested queries, such as 'internet', 'international', etc.

• Is there anything like memcached, but for sorted lists?

  - by depesz

  I have a situation where I could really benefit from having system like memcached, but with the ability to store (per each key) sorted list of elements, and modifying the list by addition of values. For example: something.add_to_sorted_list( 'topics_list_sorted_by_title', 1234, 'some_title') something.add_to_sorted_list( 'topics_list_sorted_by_title', 5436, 'zzz') something.add_to_sorted_list( 'topics_list_sorted_by_title', 5623, 'aaa') Which I then could use like this: something.get_list_size( 'topics_list_sorted_by_title' ) // returns 3 something.get_list_elements( 'topics_list_sorted_by_title', 1, 10 ) // returns: 5623, 1234, 5436 Required system would allow me to easily get items count in every array, and fetch any number of values from the array, with the assumption that the values are sorted using attached value. I hope that the description is clear. And the question is relatively simple: is there any such system?

• Is it possible to implement Flex states in Android application.

  - by barmaleikin

  Hi guys, Let me explain what I am want to archive. For example, in Flex I can create page (list of something) with 3 states: Loading state (just display some animation or label with text "Please wait."), No records state (page with text saying that there is no records) and Page with populated list. It is very easy to operate with states in Flex. Is it possible to implement something similar in Android application? I would appreciate if you provide some examples.

• Compare two object lists with LINQ on specific property

  - by Niklas

  I have these two lists (where the Value in a SelectListItem is a bookingid): List<SelectListItem> selectedbookings; List<Booking> availableBookings; I need to find the ids from selectedBookings that are not in availableBookings. The LINQ join below will only get me the bookingids that are in availableBookings, and I'm not sure how to do it the other way around. != won't work since I'm comparing strings. results = ( from s in selectedbookings join a in availableBookings on s.bookingID.ToString() equals a.Value select s);

• Help regarding no sql databases like hadoop, hbase etc

  - by user560370

  I am new to the distributed NoSQL databases like Hadoop, Cassandra, etc. I have few questions for which I seek an expert advice: Can you list problems/challenges one will generally face when making a shift from the present conventional database like MySQL to these large cluster-based databases? What are the difficulties, if any, when one needs to adapt to a newer version of these open source projects? Can you list out the things which are generally stored/kept in memcached for fast rendering of the page? How can I understand the source code of open-source projects so that I can build on it and maybe give back to the community? Above questions may sound to be idiotic and basic but please it's a request for the experts to answer the above questions in detailed and to best of their abilities.

• SSIS - SharePoint to SQL without Adapter Addin?

  - by Mark

  Hey all, Im looking to Extract a SharePoint List (WSS 2.0) to a SQL(2005) Table using SQL Server Integrated Services. First off I am aware of the "adapter" that does this from http://msdn.microsoft.com/en-us/library/dd365137.aspx however I'm just wondering for compatibility purposes if it can't just be done "out of the box". There are only a limited number of "Data Flow Sources" to select as alternatives and I am unsure if any of these would be able to work in a similar way either directly to SharePoint or via SharePoints web services (e.g. http://server_name/_vti_bin/Lists.asmx) From the list of these sources it looks like the best option would be the OLE DB connector, but not sure how it would do this. Any help you have would be great, Mark

• Creating an IF statement for datagrid value

  - by EvanRyan

  This is something I thought would be easier than it's turning out to be. For whatever reason, I can't seem to figure out a way to make what I'm trying to do here work with an If statement: List<int> miscTimes = new List<int>(); for (int i = 0; i < MISCdataGridView1.RowCount; i++) { if (MISCdataGridView1.Rows[i].Cells[2].Value == "Something") { miscTimes.Add(Convert.ToInt32(MISCdataGridView1.Rows[i].Cells[3].Value)); } } return miscTimes; For some reason, I can't get it to like anything I do with the if statement. I've tried converting to string and all of that. How should I go about this?

• Haskell: writing the result of a computation to file

  - by peterwkc

  I have a function which creates a tuple after computation, but I would like to write it to file. I know how to write to a file using writeFile, but do not know how to combine the computation and monads IO together in the type signature. This is my code. invest :: ([Char]->Int->Int->([Char], Int) ) -> [Char]->Int->Int->([Char], Int) invest myinvest x y = myinvest x y myinvest :: [Char]->Int->Int->([Char], Int) myinvest w x y | y > 0 = (w, x + y) | otherwise = error "Invest amount must greater than zero" where I have a function which computes the maximum value from a list, but I want this function to receive input from a file, and then perform the computation of maximum value. maximuminvest :: (Ord a) => [a] -> a maximuminvest [] = error "Empty Invest Amount List" maximuminvest [x] = x maximuminvest (x:xs) | x > maxTail = x | otherwise = maxTail where maxTail = maximuminvest xs Please help. Thanks.

• Is there a way to simplify this Django query?

  - by Mark

  accepted_bids = Bid.objects.filter(shipment__user=u, status='acc').select_related('shipment') completed_shipments = [] for b in accepted_bids: completed_shipments.append(b.shipment) vehicles_shipped = [] for s in completed_shipments: vehicles_shipped.extend(s.items.all()) In the end, I want a list of shipped vehicles. A vehicle is shipped if it's part of a shipment that's completed. A shipment is completed if it has an accepted bid. I'd prefer not to iterate over the querysets thereby forcing a hit to the DB before its necessary... isn't there a way to get all the associated shipments from a list of bids, for example?

• Eclipse call hierarchy skips calls in undefined #ifdef regions

  - by stupakov

  Hi all, The "call hierarchy" and "declaration" features in Eclipse CDT omit results that exist in undefined (greyed out) #ifdef regions. Example: void blah(void) { #ifndef ABC foo(); #else //line is greyed out bar(); //line is greyed out #endif //line is greyed out } The call hierarchy for foo() will list blah() as a caller; the call hierarchy for bar() will not list blah(). I'm not expecting it to do full resolution of which #define blocks will get compiled, I simply would like it to return all calls/declarations of the function I'm searching for, regardless of the #define blocks that surround it. Other IDEs such as SlickEdit are able to do this. Does anyone know of a way to get Eclipse to adopt this behavior? Thanks.

• Design RESTful service with multiple ids

  - by Dustin Digmann

  I am designing a RESTful service. It is to list a set of data. The main problem is that the set does not have a reasonable, single identifier. Nor can the specific set be easily calculated within the knowledge of the system. As a result, it does not seem possible to have a GET /items/{identifier} service. I do have the id of each element being requested. My main issue is that it does not seem RESTful to list the ids in the URI (eg GET items/{id1},{id2},...,{idn} ). Right? I could see DELETE having a similar use case - remove multiple items in one request cycle. How would such a use case be satisfied while staying within the REST realm? Is that possible?

• ant: iterator over properties file

  - by scheibenkleister

  Hi, all my projects and their versions are defined in a properties file like this: ProjectNameA=0.0.1 ProjectNameB=1.4.2 I'd like to iterate over all projects and use there names and versions in an ant script. Right now, I read the entire properties file in help of the property task. Then I iterate over a given list in a for loop like this: <for list="ProjectNameA,ProjectNameB" param="project"> <sequential> <echo message="@{project} has version ${@{project}}" /> </sequential> </for> How can I avoid the duplication of the project names in the for loop. So basically iterate over each line and extract the name and the version of a project. Thanks.

• Passing an empty IEnumerable argument to a method

  - by avance70

  I have this method (simplified): void DoSomething(IEnumerable<int> numbers); And I invoke it like this: DoSomething(condition==true?results:new List<int>()); The variable results is formed with a LINQ select condition (IEnumerable). I was wondering is this List<int>() the best way (the fastest?) to pass an empty collection, or is new int[0] better? Or, something else would be faster, a Collection, etc.? In my example null wouldn't be ok.

• Re-ordering collection C#

  - by Adam

  Hi - I have a problem which I cant seem to find answer to through searches (either that or I am searching for the completely wrong thing!). I have a list of items called "Top 10" in a sortedlist item that is populated from my DB (SortedList where int is position and string is item). I want to be able to move items up & down the list order at the click of a button and then save the new order back to the DB. I am OK with the DB part it is just the re-ordering I am really struggling with - is a sortedlist the correct collection for this? Many thanks for any advice offered.

• jquery :last missing multiple classes

  - by mickyjtwin

  I have an unordered list, and am using jquery to find the last ul and apply a class. jQuery("ul.class1:last").addClass("lastUi"); The html is as follows: <ul class="class1"></ul> <ul class="class1"></ul> This is working fine, however it has now changed in that another class is being added to the list so the html looks like: <ul class="class1"></ul> <ul class="class1 class2"></ul> <ul class="class1"></ul> <ul class="class1 class2"></ul> The jQuery code is now not picking up the last ul with both class1 and class2 as the last element and isn't adding the lastUI class.

• How to create a Appointment in a Shared Calendar (Sharepoint) with VBA (Macro)?

  - by Diogo K.

  I am actually trying to make an appointment from an excel spreadsheet. I have all the information of the appointment, like subject, body, start and end dates, I actually can create an appointment but only with my personal calendar in outlook. How do I copy/move/create an appointment in a shared calendar in a sharepoint server? I've tried: Dim apOL As Object Dim objFolder As Folder Dim cro As String Set apOL = CreateObject("Outlook.Application") Set oItem = apOL.CreateItem(olApItem) Set MAPISession = apOL.Session ... cro = "stssync://sts/?ver=1.0&type=calendar&cmd=add-folder&base-url=(MY SP SERVER)&list-url=%2FLists%2FCronograma%20%20%2Fcalendar%2Easpx&guid=%7B02717CEF%2D404F%2D482F%2DA131%2D5C3C245CD268%7D&site-name=Testes&list-name=Cronograma%20-" ... Set objFolder = MAPISession.OpenSharedFolder(cro, Null,Null,Null) It gives me the error "Type Mismatch" I'd try to get the objFolder as the Sharepoint Folder then later create an local appointment and then try an Item.Move objFolder Is it the correct way?

• Export Failed Element Log(s) after deliver?

  - by cogmios

  When a deliver has been performed I can rightlick an entry in the GUI version/element log and it displays me a popup with the element log. Quite handy. I now have a delivery with about 25 failed ones and a couple of hundred OK's. Sadly I can not sort on the column "status" so I have to make screenshots wherever I find a [!] to sit together with the specific team to find out if it is really ok to not deliver those. It would however be handy to have this list of element logs from a deliver so that I do not have to make screenshots or copy the contents of the popup box one by one but just have a list of the failed ones with the element log. Is there a way to export the element logs from a deliver (so the the ones that show up when you rightclick and choose "Display Element Log") and/or only the ones that gave failures?

• designing database tables using JDBC

  - by Noona

  I am creating a users table using JDBC and mysql, each user has a permissions list that comprises Integer values, I am wondering if I should use an array for storing these values and then have only 1 record for this user in the table, or simply create a new table that comprises 2 columns: user ID and permissions, and then have multiple records for each user that specify the user name in one columns and one permission value in the second column, the second option seems to be redundant since a permission value is a simple object that isn't associated with any other objects (like a student and courses list for example, because the course is associated with many other objects, like grade, teacher, etc, so in this case it is natural to have multiple records), but the first one seems to be a bit unnatural to me, so if someone has experience with these things and direct me? thanks
