  • Factory Method Pattern using Generics-C#

    - by nanda
    Just I am learning Generics.When i have an Abstract Method pattern like : //Abstract Product interface IPage { string pageType(); } //Concerete Product 1 class ResumePage : IPage { public string pageType() { return "Resume Page"; } } //Concrete Product 2 class SummaryPage : IPage { public string pageType() { return "SummaryPage"; } } //Fcatory Creator class FactoryCreator { public IPage CreateOnRequirement(int i) { if (i == 1) return new ResumePage(); else { return new SummaryPage(); } } } //Client/Consumer void Main() { FactoryCreator c = new FactoryCreator(); IPage p; p = c.CreateOnRequirement(1); Console.WriteLine("Page Type is {0}", p.pageType()); p = c.CreateOnRequirement(2); Console.WriteLine("Page Type is {0}", p.pageType()); Console.ReadLine(); } how to convert the code using generics?

  • Converting 24BPP to 4BPP with GDI+ in VB.NET

    - by Chris
    My VB.NET program currently takes a 4BPP TIFF as an Bitmap, converts it to a Graphic, adds some text strings and then saves it out again as a TIFF file. The output Bitmap.Save() TIFF file by default seems to be 24BPP (regardless of the input) and is a lot larger than the original TIFF. Is it possible to keep the same 4BPP palette encoding as the input for the output and if not, how can I convert my Bitmap PixelFormat from 24BPP to 4BPP Indexed. I've seen an example for converting 24 BPP to 1 BPP at http://www.bobpowell.net/onebit.htm using BitmapData.Lockbits() but cannot figure out how to do it for 4BPP. Many thanks Chris

  • Parsing plain Win32 PE File (Exe/DLL) in .NET

    - by Usman
    I need to parse plain Win32 DLL/Exe and need to get all imports and exports from it and to show it on console or GUI(say Win Forms). Is it possible to parse Win32 DLL/Exe in C#.NET, read its export table,import table and get managed types from it. As its unmanaged PE(.NET doesn't allows you to convert unmanaged PE files to managed .NET assemblies, only it generates COM managed assemblies). So how to parse export and import tables of PE files and take all methods(signatures from it) in managed form.(e.g if char* as argument, it should display as IntPtr)

  • C# -Interview Question Anonymous Type

    - by Amutha
    Recently i was asked to prove the power of C# 3.0 in a single line( might be tricky) i wrote new int[] { 1, 2, 3 }.Union(new int[]{10,23,45}). ToList().ForEach(x => Console.WriteLine(x)); and explained you can have (i) anonymous array (ii) extension method (iii)lambda and closure all in a single line.I got spot offer. But..... The interviewer asked me how will you convert an anonymous type into know type :( I am 100% sure ,we can not do that.The interviewer replied there is 200% chance to do that if you have a small work around.I was clueless. As usual,I am waiting for your valuable reply(Is it possible?).

  • Order by descending based on condition

    - by Vinni
    Hello All, I want to write a LINQ to Entity query which does order by ascending or descending based on input parameter, Is there any way for that. Following is the my code. Please suggest. public List<Hosters_HostingProviderDetail> GetPendingApproval(SortOrder sortOrder) { List<Hosters_HostingProviderDetail> returnList = new List<Hosters_HostingProviderDetail>(); int pendingStateId = Convert.ToInt32(State.Pending); //If the sort order is ascending if (sortOrder == SortOrder.ASC) { var hosters = from e in context.Hosters_HostingProviderDetail where e.ActiveStatusID == pendingStateId orderby e.HostingProviderName ascending select e; returnList = hosters.ToList<Hosters_HostingProviderDetail>(); return returnList; } else { var hosters = from e in context.Hosters_HostingProviderDetail where e.StateID == pendingStateId orderby e.HostingProviderName descending select e; returnList = hosters.ToList<Hosters_HostingProviderDetail>(); return returnList; } }

  • Alternatives to ImageMagick for PDF downsizing

    - by Craig Coston
    Having an issue with some PDF files not displaying properly in our iPad app. I have come to the conclusion that we are needing to standardize by "converting" PDF to PDF. I have successfully processed this using ImageMagick to convert the PDF to PNG (resized), and then pushing the PNG(s) back into a PDF. However, something within ImageMagick is making photos within PDFs display wrong. Same issue just converting a JPG or other graphic to PDF in ImageMagick. I solved that by taking the output of the converted ImageMagick file and converting it again using GD to PNG, then pushing it through our PDF converter. So my question is this: What other PHP workflows would work with this, other than using ImageMagick for the conversion back to PDF? We are not opposed to a paid solution, we just need something that works. Our server runs centOS.

  • Reading PowerPoint Effects with VBA

    - by OneNerd
    I have been working with VBA inside PowerPoint, and have a grasp on most things. What I am struggling with is reading the effect/animation settings for each object. I seem to be able to get a lot of what I need through the Powerpoint.ActivePresentation.Slides(slide_id).TimeLine.MainSequence(seq_num) What confuses me is how to convert the numeric value of Powerpoint.ActivePresentation.Slides(slide_id).TimeLine.MainSequence(seq_num).EffectType to an effect (so looking for a table of values to effects or perhaps a CONST table). Also, how to read in all the different level of effects (like entrance, or emphasis, etc) is really confusing. not to mention I cannot wrap my head around the timeline (which seems like it is not really a timeline). Can anyone point me to any good articles or documentation that discusses how to read the effects and animations properly and fully? Thanks.

  • how to work with strings and integers as bit strings in python?

    - by Manuel
    Hello! I'm developing a Genetic Algorithm in python were chromosomes are composed of strings and integers. To apply the genetic operations, I want to convert these groups of integers and strings into bit strings. For example, if one chromosome is: ["Hello", 4, "anotherString"] I'd like it to become something like: 0100100100101001010011110011 (this is not actual translation). So... How can I do this? Chromosomes will contain the same amount of strings and integers, but this numbers can vary from one algorithm run to another. To be clear, what I want to obtain is the bit representation of each element in the chromosome concatenated. If you think this would not be the best way to apply genetic operators (such as mutation and simple crossover) just tell me! I'm open to new ideas. Thanks a lot! Manuel

  • CMS for news editing

    - by Genrih
    It is necessary to convert the site into CMS. One of the main features - edit the articles of some type, and to do so will be non-programmers, that is, the simpler the better. Ideally - no editor like ckeditor, but simply wizard, where its possible to insert images, text, title text, and it's all displayed in the page default template. Wizard can be implemented by me, let it be just not very difficult to change the default editor. Also multilanguage support is required. What can you advise?

  • How to parse strings representing xml.dom.minidom nodes in python?

    - by Francis Davey
    I have a collection of nodes xml.dom.Node objects created using xml.dom.minidom. I store them (individually) in a database by converting them to a string using the toxml() method of a the Node object. The problem is that I'd sometimes like to be able to convert them back to the appropriate Node object using a parser of some kind. As far as I can see the various libraries shipped with python use Expat which won't parse a string like '' or indeed anything which is not a correct xml string. So, does anyone have any ideas? I realise I could pickle the nodes in some way and then unpickle them, but that feels unpleasant and I'd much rather be storing in a form I can read for maintenance purposes. Surely there is something that will do this?

  • Converting raw bytes into audio sound

    - by Afro Genius
    In my application I inherit a javastreamingaudio class from the freeTTS package then bypass the write method which sends an array of bytes to the SourceDataLine for audio processing. Instead of writing to the data line, I write this and subsequent byte arrays into a buffer which I then bring into my class and try to process into sound. My application processes sound as arrays of floats so I convert to float and try to process but always get static sound back. I am sure this is the way to go but am missing something along the way. I know that sound is processed as frames and each frame is a group of bytes so in my application I have to process the bytes into frames somehow. Am I looking at this the right way? Thanx in advance for any help.

  • What language is to binary, as Perl is to text?

    - by ehdr
    I am looking for a scripting (or higher level programming) language (or e.g. modules for Python or similar languages) for effortlessly analyzing and manipulating binary data in files (e.g. core dumps), much like Perl allows manipulating text files very smoothly. Things I want to do include presenting arbitrary chunks of the data in various forms (binary, decimal, hex), convert data from one endianess to another, etc. That is, things you normally would use C or assembly for, but I'm looking for a language which allows for writing tiny pieces of code for highly specific, one-time purposes very quickly. Any suggestions?

  • MySQL and Collation

    - by user294787
    I have a table with a column using utf8_unicode_ci character set. This table stores Japanese data and my problem is that using this character set, I'm not able to store the same word written in katakana and hiragana because it's considered to be the same word. For example ??? and ???, which mean I, me. I know that I can change the character set to utf8_general_ci to resolve this problem but is it possible to bypass this limitation ? I mean, keep utf8_unicode_ci character set and make those two words be inserted? Is it possible to make this work using CONVERT or CAST operators? Thanks.

  • How to create such a PHP array in JavaScript?

    - by dfjhdfjhdf
    How to create such a PHP array in JavaScript? $arr = array('oneKey' => array('key1' => 'value1', 'key2' => 'value2'), 'anotherKey' => array('key1' => 'value1', 'key2' => 'value2')); EDIT: Guys, I forgot to mention that I would then need a simple way to sort those array('key1' = 'value1', 'key2' = 'value2') lexicographically by its keys. EDIT2: Actually I won't "convert" it. It's a way I explain things. I am more of a php guy.

  • GPU YUV to RGB. Worth the effort?

    - by Jaime Pardos
    Hello, I have to convert several full PAL videos (720x576@25) from YUV 4:2:2 to RGB, in real time, and probably a custom resize for each. I have thought of using the GPU, as I have seen some example that does just this (except that it's 4:4:4 so the bpp is the same in source and destiny)-- http://www.fourcc.org/source/YUV420P-OpenGL-GLSLang.c However, I don't have any experience with using GPU's and I'm not sure of what can be done. The example, as I understand it, just converts the video frame to YUV and displays it in the screen. Is it possible to get the processed frame instead? Would it be worth the effort to send it to the GPU, get it transformed, and sending it again to main memory, or would it kill performance? Being a bit platform-specific, assuming I work on windows, is it possible to get an OpenGL or DirectDraw surface from a window so the GPU can draw directly to it?

  • Problem using FluentNHibernate, SQLite and Enums

    - by weenet
    I have a Sharp Architecture based app using Fluent NHibernate with Automapping. I have the following Enum: public enum Topics { AdditionSubtraction = 1, MultiplicationDivision = 2, DecimalsFractions = 3 } and the following Class: public class Strategy : BaseEntity { public virtual string Name { get; set; } public virtual Topics Topic { get; set; } public virtual IList Items { get; set; } } If I create an instance of the class thusly: Strategy s = new Strategy { Name = "Test", Topic = Topics.AdditionSubtraction }; it Saves correctly (thanks to this mapping convention: public class EnumConvention : IPropertyConvention, IPropertyConventionAcceptance { public void Apply(FluentNHibernate.Conventions.Instances.IPropertyInstance instance) { instance.CustomType(instance.Property.PropertyType); } public void Accept(FluentNHibernate.Conventions.AcceptanceCriteria.IAcceptanceCriteria criteria) { criteria.Expect(x = x.Property.PropertyType.IsEnum); } } However, upon retrieval, I get an error regarding an attempt to convert Int64 to Topics. This works fine in SQL Server. Any ideas for a workaround? Thanks.

  • How to expose a Delphi set type via Soap

    - by Wouter van Nifterick
    I'm currently creating soap wrappers for some Delphi functions so that we can easily use them from PHP, C# and Delphi. I wonder what's the best way to expose sets. type TCountry = (countryUnknown,countryNL,countryD,countryB,countryS,countryFIN,countryF,countryE,countryP,countryPl,countryL); TCountrySet = set of TCountry; function GetValidCountrySet(const LicensePlate:string; const PossibleCountriesSet:TCountrySet):TCountrySet; I'm currently wrapping it like this for the soap server: type TCountryArray = array of TCountry; function TVehicleInfo.GetValidCountrySet(const LicensePlate:string; const PossibleCountriesSet:TCountryArray):TCountryArray; It works, but I need to write a lot of useless and ugly code to convert sets--arrays and arrays--sets. Is there an easier, more elegant, or more generic way to do this?

  • Don't want to JSON serialize the whole list of classes

    - by mjmcloug
    Hey, I've got a IList of Sites in my application and Site has a large amount of properties. I'm wanting to convert this list to JSON to be used in a dropdownlist similar to this var sites = SiteRepository.FindAllSites(); return new JsonResult() { Data = sites, JsonRequestBehavior = JsonRequestBehavior.AllowGet }; the problem I have is that I only want to use the id and name properties of the site class. I was thinking a way round this would be to use an 'adaptor' class that would then only expose these two properties and I would then serialize that. The problem I have is I want to make the class generic so that it can handle any list of objects. Has anybody come across a similar situation and solved it?

  • How to return a code value into a variable

    - by Georges Sabbagh
    I have the below case in my report: Receivable: RunningValue(Fields!Receivable.Value,SUM,Nothing) Production: code.SumLookup(LookupSet(Fields!Currency_Type.Value, Fields!Currency_Type1.Value,Fields!Gross_Premium_Amount.Value, "DataSet2")) Rec/Prod: Receivable / Production. Public Function SumLookup(ByVal items As Object()) As Decimal If items Is Nothing Then Return Nothing End If Dim suma As Decimal = New Decimal() Dim ct as Integer = New Integer() suma = 0 ct = 0 For Each item As Object In items suma += Convert.ToDecimal(item) ct += 1 Next If (ct = 0) Then return 0 else return suma End Function The problem is for Rec/Prod, if prod = 0 i receive error. Ive tried to put the below condition: IIF(code.SumLookup(LookupSet(Fields!Currency_Type.Value, Fields!Currency_Type1.Value,Fields!Gross_Premium_Amount.Value, "DataSet2"))=0,0,RunningValue(Fields!Receivable.Value,SUM,Nothing)/(code.SumLookup(LookupSet(Fields!Currency_Type.Value, Fields!Currency_Type1.Value,Fields!Gross_Premium_Amount.Value, "DataSet2")))) but since in the false condition i am recalling code.SumLookup in order to get the value in regetting 0 for production and consiquently i get error for Rec/Prod. how can i call code.sumlookup on time only and save its value into a variable so i dont need to call it everytime i need to check the value. or if there any other solution please advise.

  • Using Cepstrum for PDA

    - by CziX
    Hey, I am currently deleveloping a algorithm to decide wheather or not a frame is voiced or unvoiced. I am trying to use the Cepstrum to discriminate between these two situations. I use MATLAB for my implementation. I have some problems, saying something generally about the frame, but my currently implementation looks like (I'm award of the MATLAB has the function rceps, but this haven't worked for either): ceps = abs(ifft(log10(abs(fft(frame.*window')).^2+eps))); Can anybody give me a small demo, that will convert the frame to the power cepstrum, so a single lollipop at the pitch frequency. For instance use this code to generate the frequency. fs = 8000; timelength = 25e-3; freq = 500; k = 0:1/fs:timelength-(1/fs); s = 0.8*sin(2*pi*freq*k); Thanks.

  • What is the proper way to resolve Eclipse warning "isn't parameterized"?

    - by Morinar
    I'm trying to clean up some warnings in some old Java code (in Eclipse), and I'm unsure what the proper thing to do is in this case. The block looks more or less like this: Transferable content = getToolkit().getSystemClipboard().getContents( null ); java.util.List clipboardFileList = null; if( content.isDataFlavorSupported( DataFlavor.javaFileListFlavor ) ) { try { clipboardFileList = (java.util.List)content.getTransferData( DataFlavor.javaFileListFlavor); } /* Do other crap, etc. */ } The List generates a warning as it isn't parameterized, however, if I parameterize it with <File>, which I'm pretty sure is what it requires, it complains that it can't convert from Object to List<File>. I could merely suppress the unchecked warning for the function, but would prefer to avoid that if there is a "good" solution. Thoughts?

  • Arrays of pointers to arrays?

    - by a2h
    I'm using a library which for one certain feature involves variables like so: extern const u8 foo[]; extern const u8 bar[]; I am not allowed to rename these variables in any way. However, I like to be able to access these variables through an array (or other similar method) so that I do not need to continually hardcode new instances of these variables into my main code. My first attempt at creating an array is as follows: const u8* pl[] = { &foo, &bar }; This gave me the error cannot convert 'const u8 (*)[]' to 'const u8*' in initialization, and with help elsewhere along with some Googling, I changed my array to this: u8 (*pl)[] = { &foo, &bar }; Upon compiling I now get the error scalar object 'pl' requires one element in initializer. Does anyone have any ideas on what I'm doing wrong? Thanks.

  • Converting a year from 4 digit to 2 digit and back again in C#

    - by Mike Wills
    My credit card processor requires I send a two-digit year from the credit card expiration date. Here is how I a currently processing: I put a DropDownList of the 4-digit year on the page. I validate the expiration date in a DateTime field to be sure that the expiration date being passed to the CC processor isn't expired. I send a two-digit year to the CC processor (as required). I do this via a substring of the value from the year DDL. Is there a method out there to convert a four-digit year to a two-digit year. I am not seeing anything on the DateTime object. Or should I just keep processing it as I am?
