  • python array.array with strings as data type

    - by Gladius
    Is there an object that acts like array.array, yet can handle strings (or character arrays) as its data type? It should be able to convert the string array to binary and back again, preferably with null terminated strings, however fixed length strings would be acceptable. >>> my_array = stringarray(['foo', 'bar']) >>> my_array.tostring() 'foo\0bar\0' >>> re_read = stringarray('foo\0bar\0') >>> re_read[:] ['foo', 'bar'] I will be using it with arrays that contain a couple million strings.

  • determine complex type from a primitive type using reflection

    - by Nilotpal Das
    I am writing a tool where I need to reflect upon methods and if the parameters of the methods are complex type, then I need to certain type of actions such as instantiating them etc. Now I saw the IsPrimitive property in the Type variable. However, it shows string and decimal as complex types, which technically isn't incorrect. However what I really want is to be able to distinguish developer created class types from system defined data types. Is there any way that I can do this?

  • Split a complex GUI window into several files in Netbeans

    - by Hectoret
    After building the application GUI, I realised it was a little bit too complex and I could reuse some of the Swing components. The result is a complex class with many anidated JPanels. My question is: does Netbeans provide a way to split a JPanel and its children components into a different class? If I do it by hand, will the GUI designer still work? Thanks!

  • Tool/Program/Script/Formula for deciphering Active Directory Connection Strings for 3rd party user i

    - by I.T. Support
    We're using WSFTP, which has an Active Directory Integration module. To populate the user accounts you need to provide a connection string akin to: OU=Users,DC=domain,DC=com CN=Domain Users,OU=Users,DC=domain,DC=com Questions: Is there a Tool/Program/Script/Formula that allows me to decipher how these strings might look based on what I can see in Active Directory Users & Computers? Is there a proper/accepted name for these types of connection strings? I don't even know what to Google to get more information about how to format one properly How would I troubleshoot the connection string if I think it looks correctly formatted, but it isn't working? Thanks!

  • How does Ocaml decide precedence for user-defined operators?

    - by forefinger
    I want nice operators for complex arithmetic to make my code more readable. Ocaml has a Complex module, so I just want to add operators that call those functions. The most intuitive way for me is to make a new complex operator from all of the usual operators by appending '&' to the operator symbol. Thus +& and *& will be complex addition and multiplication. I would also like ~& to be complex conjugation. If I'm going to use these operators, I want them to associate the same way that normal arithmetic associates. Based on the following sessions, they are automatically behaving the way I want, but I would like to understand why, so that I don't get horrible bugs when I introduce more operators. My current guess is that their precedence is done by lexically sorting the operator symbols according to an ordering that is consistent with normal arithmetic precedence. But I cannot confirm this. Session one: # open Complex;; # let (+&) a b = add a b;; val ( +& ) : Complex.t -> Complex.t -> Complex.t = <fun> # let ( *&) a b = mul a b;; val ( *& ) : Complex.t -> Complex.t -> Complex.t = <fun> # one +& zero *& one +& zero *& one;; - : Complex.t = {re = 1.; im = 0.} # zero +& one *& zero +& one *& zero;; - : Complex.t = {re = 0.; im = 0.} # i +& i *& i +& i *& i *& i;; - : Complex.t = {re = -1.; im = 0.} Session two: # open Complex;; # let ( *&) a b = mul a b;; val ( *& ) : Complex.t -> Complex.t -> Complex.t = <fun> # let (+&) a b = add a b;; val ( +& ) : Complex.t -> Complex.t -> Complex.t = <fun> # one +& zero *& one +& zero *& one;; - : Complex.t = {re = 1.; im = 0.} # zero +& one *& zero +& one *& zero;; - : Complex.t = {re = 0.; im = 0.} # i +& i *& i +& i *& i *& i;; - : Complex.t = {re = -1.; im = 0.} # let (~&) a = conj a;; val ( ~& ) : Complex.t -> Complex.t = <fun> # (one +& i) *& ~& (one +& i);; - : Complex.t = {re = 2.; im = 0.}

  • Html.DropDownListFor<> and complex object in ASP.NET MVC2

    - by dagda1
    Hi, I am looking at ASP.NET MVC2 and trying to post a complex object using the new EditorFor syntax. I have a FraudDto object that has a FraudCategory child object and I want to set this object from the values that are posted from the form. Posting a simple object is not a problem but I am struggling with how to handle complex objects with child objects. I have the following parent FraudDto object whcih I am binding to on the form: public class FraudDto { public FraudCategoryDto FraudCategory { get; set; } public List<FraudCategoryDto> FraudCategories { get; private set; } public IEnumerable<SelectListItem> FraudCategoryList { get { return FraudCategories.Select(t => new SelectListItem { Text = t.Name, Value = t.Id.ToString() }); } The child FraudCategoryDto object looks like this: public class FraudCategoryDto { public int Id { get; set; } public string Name { get; set; } } On the form, I have the following code where I want to bind the FraudCategoryDto to the dropdown. The view is of type ViewPage: <td class="tac"> <strong>Category:</strong> </td> <td> <%= Html.DropDownListFor(x => x.FraudCategory, Model.FraudTypeList)%> </td> I then have the following controller code: [HttpPost] public virtual ViewResult SaveOrUpdate(FraudDto fraudDto) { return View(fraudDto); } When the form is posted to the server, the FraudCategory property of the Fraud object is null. Are there any additional steps I need to hook up this complex object? Cheers Paul

  • XAML Binding to complex value objects

    - by Gus
    I have a complex value object class that has 1) a number or read-only properties; 2) a private constructor; and 3) a number of static singleton instance properties [so the properties of a ComplexValueObject never change and an individual value is instantiated once in the application's lifecycle]. public class ComplexValueClass { /* A number of read only properties */ private readonly string _propertyOne; public string PropertyOne { get { return _propertyOne; } } private readonly string _propertyTwo; public string PropertyTwo { get { return _propertyTwo; } } /* a private constructor */ private ComplexValueClass(string propertyOne, string propertyTwo) { _propertyOne = propertyOne; _propertyTwo = PropertyTwo; } /* a number of singleton instances */ private static ComplexValueClass _complexValueObjectOne; public static ComplexValueClass ComplexValueObjectOne { get { if (_complexValueObjectOne == null) { _complexValueObjectOne = new ComplexValueClass("string one", "string two"); } return _complexValueObjectOne; } } private static ComplexValueClass _complexValueObjectTwo; public static ComplexValueClass ComplexValueObjectTwo { get { if (_complexValueObjectTwo == null) { _complexValueObjectTwo = new ComplexValueClass("string three", "string four"); } return _complexValueObjectTwo; } } } I have a data context class that looks something like this: public class DataContextClass : INotifyPropertyChanged { private ComplexValueClass _complexValueClass; public ComplexValueClass ComplexValueObject { get { return _complexValueClass; } set { _complexValueClass = value; PropertyChanged(this, new PropertyChangedEventArgs("ComplexValueObject")); } } } I would like to write a XAML binding statement to a property on my complex value object that updates the UI whenever the entire complex value object changes. What is the best and/or most concise way of doing this? I have something like: <Object Value="{Binding ComplexValueObject.PropertyOne}" /> but the UI does not update when ComplexValueObject as a whole changes.

  • Complex Forms Generating Error

    - by user1648020
    I am working on an application that allows students to create a catalog of courses they are taking for a semester. I have created models for user; course; subject and category. Users can have many courses. Each course can have many subjects and categories. The tables for courses, subjects and categories include the following: Catalog: user_id; subject_id, category_id and course_id Courses: user_id; coursedetail_id Coursedetail: name; description Subject: name; description Category: name; description The idea is that an Admin can create a list of courses; subjects and categories and that the user can select the courses they want to add to their catalog. I have seperated courses and coursedetails because I envision that the coursedetails will grow overtime and the courses table will allow me to join the user_id and cousres details to rreport on if necessary. I attempted to follow Ryan's railscast on Complex Forms thinking that that I should use a complex form and has many relationship to get things working -- but I get an error in the catalog controller - cannot locate catalog_id which I know is in the table. I am now not sure if complex forms is the way to go or I should be looking at another direction to get the appropriate form in place. Any assistance would be appreciated.

  • Searching through large data set

    - by calccrypto
    how would i search through a list with ~5 mil 128bit (or 256, depending on how you look at it) strings quickly and find the duplicates (in python)? i can turn the strings into numbers, but i don't think that's going to help much. since i haven't learned much information theory, is there anything about this in information theory? and since these are hashes already, there's no point in hashing them again

  • if string is alphabetically greater than other string in objective

    - by Jonathan
    I'm trying to use an if statement to work out which of 2 strings comes first alphabetically. Like with numbers and greater and less than: if (1 < 2) { just with strings: if(@"ahello" < @"bhello") { Or would I have to have a string containing all the letters and then check the index of the first char in each string and see which index is greater, and the index that is less than the other comes first in the alphabet and then if they are equal move on to the next char and repeat?

  • Problem retrieving Strings from varbinary columns using HIbernate and MySQL

    - by user303396
    Hello, Here's my scenario. I save a bunch of Strings containing asian characters in MySQL using Hibernate. These strings are written in varbinary columns. Everything works fine during the saving operation. The DB contains the correct values (sequence of bytes). If I query (again using Hibernate) for the Strings that I saved I get the correct results. But when Hibernate fills the entity to which the Strings belong with the values from the DB I get different values then the ones I used in the query that retrieved them. Instead of receiving the correct values I receive a bunch of FFFD replacement characters. For example: if I store "??" in the DB and then I query for it, the resulting String will be \uFFFD\uFFFD\uFFFD\uFFFD\uFFFD\uFFFD. the DB connection has the following parameters set useUnicode=true&characterEncoding=UTF-8, I've tried using the true UTF-8 configurations for Hibernate but that didn't solve the problem What am I missing? Any suggestions? Thanks

  • How to easily map c++ enums to strings

    - by Roddy
    I have a bunch of enum types in some library header files that I'm using, and I want to have a way of converting enum values to user strings - and vice-versa. RTTI won't do it for me, because the 'user strings' need to be a bit more readable than the enumerations. A brute force solution would be a bunch of functions like this, but I feel that's a bit too C-like. enum MyEnum {VAL1, VAL2,VAL3}; String getStringFromEnum(MyEnum e) { switch e { case VAL1: return "Value 1"; case VAL2: return "Value 2"; case VAL1: return "Value 3"; default: throw Exception("Bad MyEnum"); } } I have a gut feeling that there's an elegant solution using templates, but I can't quite get my head round it yet. UPDATE: Thanks for suggestions - I should have made clear that the enums are defined in a third-party library header, so I don't want to have to change the definition of them. My gut feeling now is to avoid templates and do something like this: char * MyGetValue(int v, char *tmp); // implementation is trivial #define ENUM_MAP(type, strings) char * getStringValue(const type &T) \ { \ return MyGetValue((int)T, strings); \ } ; enum eee {AA,BB,CC}; - exists in library header file ; enum fff {DD,GG,HH}; ENUM_MAP(eee,"AA|BB|CC") ENUM_MAP(fff,"DD|GG|HH") // To use... eee e; fff f; std::cout<< getStringValue(e); std::cout<< getStringValue(f);

  • Efficient algorithm for finding largest eigenpair of small general complex matrix

    - by mklassen
    I am looking for an efficient algorithm to find the largest eigenpair of a small, general (non-square, non-sparse, non-symmetric), complex matrix, A, of size m x n. By small I mean m and n is typically between 4 and 64 and usually around 16, but with m not equal to n. This problem is straight forward to solve with the general LAPACK SVD algorithms, i.e. gesvd or gesdd. However, as I am solving millions of these problems and only require the largest eigenpair, I am looking for a more efficient algorithm. Additionally, in my application the eigenvectors will generally be similar for all cases. This lead me to investigate Arnoldi iteration based methods, but I have neither found a good library nor algorithm that applies to my small general complex matrix. Is there an appropriate algorithm and/or library?

  • Parse Complex WSDL Parameter Information in C#

    - by jaws
    I am attempting to parse WSDL, along the lines of the example given here. The author notes, in the comments, that the example is not capable of drilling down into complex data types. And in fact, when I run the example, it does not appear to even handle simple data types. I have poked around in System.Web.Services.Description.ServiceDescription class, which is used in the example, but cannot find any actual parameter or return type information at run-time. I gather that I may need to do some manual parsing of an xsd file? Both google and stackoverflow appear to lack a complete example of how to drill down into complex types programmatically, so... how should I do this?

  • How to generate complex url like stackoverflow?

    - by Freewind
    I'm using playframework, and I hope to generate complex urls like stackoverflow. For example, I want to generate a question's url: http://aaa.com/questions/123456/How-to-generator-a-complex-url Note the last part, it's the title of the question. But I don't know how to do it. UPDATED In the playframework, we can define routes in conf/routes file, and what I do is: GET /questions/{<\d+>id} Questions.show In this way, when we call @{Questions.show(id)} in views, it will generate: http://aaa.com/questions/123456 But how to let the generated has a title part, is difficult.

  • How to add some complex structure in multiple places in an XML file

    - by Guillaume
    I have an XML file which has many section like the one below: <Operations> <Action [some attributes ...]> [some complex content ...] </Action> <Action [some attributes ...]> [some complex content ...] </Action> </Operations> I have to add an <Action/> to every <Operations/>. It seems that an XSLT should be a good solution to this problem: <xsl:template match="Operations/Action[last()]"> <xsl:copy> <xsl:apply-templates select="@*|node()"/> </xsl:copy> <Action>[some complex content ...]</Action> </xsl:template> <xsl:template match="@*|node()"> <xsl:copy> <xsl:apply-templates select="@*|node()"/> </xsl:copy> </xsl:template> My problem is that the content of my <Action/> contains some xPath expressions. For example: <Action code="p_histo01"> <customScript languageCode="gel"> <gel:script xmlns:core="jelly:core" xmlns:gel="jelly:com.niku.union.gel.GELTagLibrary" xmlns:soap="jelly:com.niku.union.gel.SOAPTagLibrary" xmlns:soap-env="http://schemas.xmlsoap.org/soap/envelope/" xmlns:sql="jelly:sql" xmlns:x="jelly:xml" xmlns:xog="http://www.niku.com/xog" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> <sql:param value="${gel_stepInstanceId}"/> </gel:script> </customScript> </Action> The ${gel_stepInstanceId} is interpreted by my XSLT but I would like it to be copied as-is. Is that possible? How?

  • How To Use ObjectDataSource With Complex Objects and FormView Control

    - by obautista
    I have a complex object. For example a SCHOOL object that contains a collection of PERSON object. How can I use the ObjectDataSource control with a FormView and flatten the complex object? An example display would be to display the school name and comma separate the students on the page. Is this possible? I.E. public string Id { get { return m_id; } set { m_id = value; } } public string SchoolName { get { return m_schoolName; } set { m_schoolName = value; } } public List(Person Students { get { return m_students; } set { m_cast = students; } }

  • Flagging complex properties as Browsable in the compact framework

    - by Rowland Shaw
    I'm working on a compact framework project and whilst most of the properties are fairly straight forward (I.e. mark them as browsable in the xmta file), I'm struggling to get this to work for more complex types - on the full framework, I'd just implement a custom TypeConverter and go from there, but it seems the CF TypeConverter doesn't have any of the type converting methods to override, which has left me a little stuck? It probably should be blindingly obvious but how would I go about supporting design time property support for more complex types (for the sake of argument, assume I can already convert to and from a string, but I'd prefer to keep this strongly typed, rather than just pretend it was a string and parse it both ways. Where should I be looking to achieve this?

  • Printing complex widgets in Qt

    - by Jens
    I have a complex widget with tons of different subwidgets, e.g. subclasses of QLabel. I want to print this widget, but obviously I do not want to print the background, I want to print with differing text colors or have the style of frames slightly modified. As I do not really want to iterate through all subwidgets with a special "print" function, which I would need to attach to all widgets (how to add "print" to a QLabel?), I would like to use paintEvent. If I have a hierarchy MyWidget - derived from - some QWidget, I would like to insert a sublayer MyWidget - MyPrintWidget - some QWidget, where myPrintWidget::paintEvent would check, if the current print is going to the screen (thus call QWidget::paintEvent), else if we are printing to the printer, call some function MyPrintWidget::drawWidget instead. Is this the right way to print-enable a widget? How can I figure out in paintEvent, that I'm printing to a printer instead of the screen? Is there a good example of printing complex widgets?

  • Programatically convert complex Excel file into HTML format

    - by shuby_rocks
    Hello all, I have a set of complex Excel files (with figures in it) that I want to show in a web browser. So I need to convert them into HTML page first. Since the excel files are very complex, I can not just parse them and generate a HTML table with HTML tags. The current manual solution that works fine is when I use Microsoft Excel software to save the spreadsheet as a HTML page. I want to automate this task in some way since I want to do it progrmatically through Java. Is their any existing solution or a way to do it? Thanks.

  • Algorithm for disordered sequences of strings

    - by Kinopiko
    The Levenshtein distance gives us a way to calculate the distance between two similar strings in terms of disordered individual characters: quick brown fox quikc brown fax The Levenshtein distance = 3. What is a similar algorithm for the distance between two strings with similar subsequences? For example, in quickbrownfox brownquickfox the Levenshtein distance is 10, but this takes no account of the fact that the strings have two similar subsequences, which makes them more "similar" than completely disordered words like quickbrownfox qburiocwknfox and yet the completely disordered version has a Levenshtein distance of eight. What distance measures exist which take the length of subsequences into account, without assuming that the subsequences can be easily broken into distinct words?
