  • How to use LIKE query in sqlite & iPhone

    - by 4thSpace
    I'm using the following for a LIKE query. Is this technique for LIKE correct? selectstmtSearch = nil; if(selectstmtSearch == nil){ const char *sql = "SELECT col1, col2 FROM table1 t1 JOIN table2 t2 ON t1.cityid = t2.cityid where t1.cityname like ?001 order by t1.cityname"; if(sqlite3_prepare_v2(databaseSearch, sql, -1, &selectstmtSearch, NULL) == SQLITE_OK) { sqlite3_bind_text(selectstmtSearch, 1, [[NSString stringWithFormat:@"%%%@%%", searchText] UTF8String], -1, SQLITE_TRANSIENT); } } The problem I'm having is after a few uses of this, I get an error 14 on sqlite3_open(), which is unable to open database. If I replace the LIKE with something such as: SELECT col1, col2 FROM table1 t1 JOIN table2 t2 ON t1.cityid = t2.cityid where t1.cityname = ? order by t1.cityname It works fine. I do open/close the DB before after the above code. Is there a way to troubleshoot exactly why the database can't be opened and what its relationship to my LIKE syntax is?

  • RenderPartial from different folder in RAZOR

    - by Dien
    I've been trying to convert my aspx pages to cshtml and having an issue with rendering partial pages from another folder. What I used to do: <% Html.RenderPartial("~/Views/Inquiry/InquiryList.ascx", Model.InquiryList.OrderBy("InquiryId", MvcContrib.Sorting.SortDirection.Descending));%> I would think that the equivalent would be: @Html.RenderPartial("~/Views/Inquiry/_InquiryList.cshtml", Model.InquiryList.OrderBy("InquiryId", MvcContrib.Sorting.SortDirection.Descending)) This is obviously not working, I am getting the following error. CS1973: 'System.Web.Mvc.HtmlHelper' has no applicable method named 'Partial' but appears to have an extension method by that name. Extension methods cannot be dynamically dispatched. Consider casting the dynamic arguments or calling the extension method without the extension method syntax. How would I achieve this with using the Razor view engine?

  • Dynatree multi - selection implementaion ala Windows style

    - by gnomixa
    I would like to implement windows style multi-selection: when user holds CTRL key and selects several nodes of the tree. Dynatree (from here http://wwwendt.de/tech/dynatree/doc/dynatree-doc.html) by default has checkboxes for node selection which my client doesn't seem to like. My question is, is it possible to implement what I need using provided set of callbacks? also, curently, when I hold CTRL key and click on the node, it opens a new window. Is there any way to suppress this functionality? i am guess I would have to do through CSS?

  • Structuremap and generic types

    - by James D
    Hi I have a situation which seems a bit different from others I've seen. For clarrification, this isn't the normal question eg; something like IAClass maps to AClass etc - that involves using basically a single concrete classes per interface. This involves having a single generic class, but I want to be able to load ALL possible usages of it. Eg - the main class is of public class MyClass<TDomainObject> : IMyClass<TDomainObject> where TDomainObject : DomainObject So example usages would be IMyClass<Person> p = new MyClass<Person>; IMyClass<Employer> p = new MyClass<Employer>; I.e. for all DomainObjects I would like to be able to load a MyClass< for. So you can see I don't use a specific class for each declaration, they all use the same one. How would I get this loaded into StructureMap?

  • Is there an HTML browser rendering engine for Ruby?

    - by Jose
    Given a URL, I would like to be able to render the returned HTML to know width and height for each div, fonts' size for each piece of text, color of each element, position of each element on screen, etc. A possible approach could be traversing the DOM tree with Hpricot and checking CSS style by parsing the associated stylesheet using css_parser gem. But this would not consider default styles, inheritance, floats, etc. In Java there's Cobra, a Java Web Renderer, which is able to render a web page and query attributes like width, font size, etc. for each fragment. I could use Cobra with JRuby or similar solutions, but prefer a Ruby native tool. Is there any library like this for Ruby?

  • Use Any() and Count() in Dynamic Linq

    - by ArpanDesai
    I am trying to write dynamic Linq Library query to fetch record on condition, Customers who has order count is greater than 3 and ShipVia field equal 2. Below is my syntax what i have tried. object[] objArr = new object[10]; objArr[0] = 1; IQueryable<Customer> test = db.Customers.Where("Orders.Count(ShipVia=2)", objArr); and IQueryable<Customer> test = db.Customers.Where("Orders.Any(ShipVia=2).Count()", objArr); But both are not working. In second query Any returns true so it won't work with Count. Suggest me a way to implement this.

  • MVVM in a canvas with usercontrols

    - by Mauro Destro
    I have a MVVM WPF application that basically wants to be a single line diagram designer for an electrical distribution network. I have a canvas that must contains transformers, circuit breaker, lines and cables. My big problem is the design... How can i start? I think about a DesignerView, DesignerViewModel that contains an ObservableCollection of IDesignerItemViewModel that is my base class for all the element. But in this case I have to use ItemsControl to bind the content of the canvas to my collection but the pros is that I don't have to create usercontrol for each element but i'll solve most of the problems with DataTemplate (i suppose). Each element viewmodel mantain a link to a model persisted in a repository where i mantain my logical tree. Any hint about how to proceed, I have looked at many DiagramCanvas example but all of those use simple items most like simple rectangle...

    - by John Retallack
    I have the following problem : I am given a tree with N apples, for each apple I am given it's weight and height,I can pick apples up to a given height H,each time I pick an apple the height of every apple is increased with U(also given).I have to find out the maximum weight of apples I can pick. e.g: N=4 H=100 U=10 (height-eight) apple1: 91 10 apple2: 82 30 apple3: 93 5 apple4: 94 15 The answer is 45 : I first pick the apple with the weight of 15 then the one with the weight of 30. I would like to know if someone here could help me with giving me an hint on how I should approach this problem. Thank you.

  • HQL recursion, how do I do this?

    - by niklassaers
    Hi guys, I have a tree structure where each Node has a parent and a Set<Node> children. Each Node has a String title, and I want to make a query where I select Set<String> titles, being the title of this node and of all parent nodes. How do I write this query? The query for a single title is this, but like I said, I'd like it expanded for the entire branch of parents. SELECT node.title FROM Node node WHERE node.id = :id Cheers Nik

  • Copy task in Visual Studio 2008

    - by Maurizio Reginelli
    This is a question related to a previous question I posted (see here). I need to configure a .csproj file to copy some files from a directory to another one (let me call them SOURCE and DESTINATION). I also need to change the SOURCE path depending from the configuration I'm using. For example, if I compile my project in Debug mode, the SOURCE path must contain a subfolder called Debug. I tried the solution proposed by Schmitt in the previous post, using $(ConfigurationName) to set the dynamic directory into the SOURCE path. When I opened the solution containing that project, a list of links to the source files appeared in the main tree of the project and they were correctly related to the Debug mode. But when I changed to the Release mode, I saw that the path of the linked source files were set again to the Debug version. Is there a way to specify a parameter in the Include attribute of the SourceFiles element? Thank you.

  • UITableView backgroundColor always grey on iPad

    - by rjobidon
    Hi, When I set the backgroundColor for my UITableView it works fine on iPhone (device and simulator) but NOT on the iPad simulator. Instead I get a light grey background for any color I set including groupTableViewBackgroundColor. Steps to reproduce: Create a new navigation-based project. Open RootViewController.xib and set the table view style to "Grouped". Add this responder to the RootViewController:- (void)viewDidLoad { [super viewDidLoad]; self.view.backgroundColor = [UIColor blackColor]; } Select Simulator SDK 3.2, build and run. You will get a black background (device and simulator). Select your target in the project tree. Click on Project : Upgrade Current Target for iPad. Build and run. You will get a light grey background. Revert the table view style to Plain and you will get a black background. Thanks for your help!

  • Compile C# into objective-C

    - by Ali Shafai
    Now that monotouch is being banned, I was wondering if there is a way to translate C# (or some other modern language for that matter) into objective-C? I won't mind using apple's api as long as I don't have to declare my variables in 3-4 stages (ivar-property-synthesize-dealloc). All I want is a less wordy language to concentrate on my intent and not on the compiler syntax. unfortunately apple in its arrogance thinks objective-c is a "modern" language and if you are looking for an alternative (monotouch) it's because you are incapable of coding. also if you don't find programming in itunes; sorry, xcode enjoyable, it is not because there are better alternatives, it's because you are stupid. anyway back to my original question: can it be done?

  • Merging deletes in a Team Foundation Server baseless merge

    - by Justin Dearing
    I have two TFS branches that do not have a direct parent/child relationship in TFS. In a certain revision, 94 in my example, several items were deleted. I have been tasked with applying those deletes to the main branch. I'd like to do so through a baseless merge. I tried the following command to do so: tf merge /baseless /recursive /version:94 .\programs\program1 ..\Release\programs\program1 Most of the items in the tree were marked as "merge", and some were marked as "merge edit". However, none of the items were deleted at the destination. On a whim i tried to merge over a single delete like so: tf merge /baseless /recursive /version:94 .\programs\program1\source1.cs ..\Release\programs\program1\source1.cs I got the following error message: The item [TFS_PATH] does not exist at the specified version. How do I do this? Is there a way to avoid making all those deletes myself?

  • What parser generator do you recommend

    - by stefan.ciobaca
    I'm currently shopping for a FOSS parser generator for a project of mine. It has to support either C or C++. I've looked at bison/flex and at boost::spirit. I went from writing my own to spirit to bison to spirit to bison to spirit, each time hit by some feature I found unpleasant. The thing I hate most about bison/flex is that they actually generate C/C++ source for you. There are a number of disadvantages to this, e.g. debugging. I like spirit from this point of view, but I find it very very heavy on syntax. I am curious about what you are using, what you would recommend, and general thoughts about the state of the art in parser generators. I am also curious to hear about approaches being used in other languages for parsing problems.

  • Cloning a read-write github repository using TortoiseHg

    - by Nathan Palmer
    I'm trying to clone my personal fork on github using the git+ssh protocol with TortoiseHg. It's giving me a rather strange error. Here is the command hg clone git+ssh//[email protected]:myusername/thefork.git This is after I have installed the hg-git module and it works just fine to clone using the git:// syntax. But I believe it's having trouble with the ssh. The error I'm getting is this. importing Hg objects into Git [Error 2] The system cannot find the file specified I have tried adding manually the ssh command into the mercurial.ini file like this [ui] username = [email protected] ssh="C:\Program Files\TortoiseHg\TortoisePlink.exe" -ssh -2 -i "C:\Source\SSHPrivateKey.ppk" But I still get the same error. Any ideas? Thanks.

  • Best way to implement a Parsing/Editable Richtextbox in WPF

    - by lozzar
    I'm trying to implement (as a prototype initially), a richtextbox control which can be parsed in real time to apply certain formatting options to it. This is being done in WPF so I thought the best way to go about it would be to extend the existing rich text box control. I've run into the issue where it isn't documented well and the examples are quite slow (the ones I found have parse the whole document on every keystroke). The way I've currently decided to go about it is to create a custom Inline element which can hold the formatting tags, and the contents. Hence I only have to parse the current paragraph and the runs in that paragraph for formatting tags. Is there a better way to achieve this? Note this isn't for code/syntax based documents (so AvalonEdit isn't appropriate). Cheers

  • Sparse O(1) array with indices being consecutive products

    - by Kos
    Hello, I'd like to pre-calculate an array of values of some unary function f. I know that I'll only need the values for f(x) where x is of the form of a*b, where both a and b are integers in range 0..N. The obvious time-optimized choice is just to make an array of size N*N and just pre-calculate just the elements which I'm going to read later. For f(a*b), I'd just check and set tab[a*b]. This is the fastest method possible - however, this is going to take a lot of space as there are lots of indices in this array (starting with N+1) which will never by touched. Another solution is to make a simple tree map... but this slows down the lookup itself very heavily by introducing lots of branches. No. I wonder - is there any solution to make such an array less sparse and smaller, but still quick branchless O(1) in lookup?

  • Data Structure Behind Amazon S3s Keys (Filtering Data Structure)

    - by dimo414
    I'd like to implement a data structure similar to the lookup functionality of Amazon S3. For those of you who don't know what I'm taking about, Amazon S3 stores all files at the root, but allows you to look up groups of files by common prefixes in their names, therefore replicating the power of a directory tree without the complexity of it. The catch is, both lookup and filter operations are O(1) (or close enough that even on very large buckets - S3's disk equivalents - both operations might as well be O(1))). So in short, I'm looking for a data structure that functions like a hash map, with the added benefit of efficient (at the very least not O(n)) filtering. The best I can come up with is extending HashMap so that it also contains a (sorted) list of contents, and doing a binary search for the range that matches the prefix, and returning that set. This seems slow to me, but I can't think of any other way to do it. Does anyone know either how Amazon does it, or a better way to implement this data structure?

  • Creating a specialised view filtering form in Rails

    - by Schroedinger
    G'day guys, I have a current set of data, and I generate multiple analyses of this data (each analysis into its own active record item called a pricing_interval) using a helper function at the moment. Currently to analyse the set of data, you need a start time(using datetime_select) an integer (using text_field) and a name (using text_field) I would like on submission of the form to be redirected to the index page of my pricing_interval, as the values will be re-generated. Manually generating a range proves that my helper methods work. How would I build a form that on submit would send parameters to a function in the form of (date,integer,name) so that it could immediately begin work whilst redirecting the user to server/pricing_intervals Anything at all would help, I've spent hours over the past few days trying to get the rails form syntax working properly to no avail, a really straightforward guide to what I would implement to get this working would be amazingly appreciated. I've looked through the form guides, as I'm not creating an object, but merely parsing params, there's got to be an easy way to do this, right?
