  • GUI and Threading

    - by cam
    Isn't there a better way to handle GUI (WinForms) from another thread than creating a delegate for every single method I need to use? It seems like there would be a better way. Here's the current code I use for every single GUI method: private delegate void SetStatusTextDelegate(string set_text); public void SetStatusText(string set_text) { if (status_prog.InvokeRequired) { status_prog.Invoke(new SetStatusTextDelegate(SetStatusText), set_text); } else { status_prog.Text = set_text; } }

    I have an entity with Integer attributes that looks like this in proto code: class MyEntity: String name Integer frequency Integer type def getFrequency() def getType() get* accessors return strings according to this table. value(type) HumanReadableString(type) 1 BSD 2 Apache 3 GPL min frequency max frequency HumanReadableString(frequency) 0 1000 rare 1000 2000 frequent 2001 3000 sexy It should be possible to get all possible values that an attribute can take, example: getChoices(MyEntity, "type") returns ("rare", "frequent", "sexy") It should be possible to get the bound value from the string: getValue(MyEntity, "frequency", "sexy") returns (2000,3000)

  • How to perform add/update of a model object that contains EntitySet

    - by David Liddle
    I have a similar concept to the SO questions/tags scenario however am trying to decide the best way of implementation. Tables Questions, QuestionTags and Tags Questions QuestionTags Tags --------- ------------ ---- QID QID TID QName TID TName When adding/updating a question I have 2 textboxes. The important part is a single textbox that allows users to enter in multiple Tags separated by spaces. I am using Linq2Sql so the Questions model has an EntitySet of QuestionTags with then link to Tags. My question is regarding the adding/updating of Questions (part 1), and also how to best show QuestionTags for a Question (part 2). Part 1 Before performing an add/update, my service layer needs to deal with 3 scenarios before passing to their respective repositories. Insert Tags that do not already exist Insert/Update Question Insert QuestionTags - when updating need to remove existing QuestionTags Here is my code below however started to get into a bit of a muddle. I've created extension methods on my repositories to get Tags WithNames etc. public void Add(Question q, string tags) { var tagList = tags.Split(new string[] { " " }, StringSplitOptions.RemoveEmptyEntries).ToList(); using (DB.TransactionScope ts = new DB.TransactionScope()) { var existingTags = TagsRepository.Get() .WithName(tagList) .ToList(); var newTags = (from t in tagList select new Tag { TName = t }).Except(existingTags, new TagsComparer()).ToList(); TagsRepository.Add(newTags); //need to insert QuestionTags QuestionsRepository.Add(q); ts.Complete(); } } Part 2 My second question is, when displaying a list of Questions how is it best to show their QuestionTags? For example, I have an Index view that shows a list of Questions in a table. One of the columns shows an image and when the user hovers over it shows the list of Tags. My current implementation is to create a custom ViewModel and show a List of QuestionIndexViewModel in the View. QuestionIndexViewModel { Question Question { get; set; } string Tags { get; set; } } However, this seems a bit clumsy and quite a few DB calls. public ViewResult Index() { var model= new List<QuestionIndexViewModel>(); //make a call to get a list of questions //foreach question make a call to get their QuestionTags, //to be able to get their Tag names and then join them //to form a single string. return View(model); } Also, just for test purposes using SQL Profiler, I decided to iterate through the QuestionTags entity set of a Question in my ViewModel however nothing was picked up in Profiler? What would be the reason for this?

  • Base32 Decoding

    - by trampster
    I have a base32 string which I need to convert to a byte array. And I'm having trouble finding a conversion method in the .net framework. I can find methods for base64 but not for base32. Convert.FromBase64String – something like this for base32 would be perfect. Is there such a method in the framework or do I have to roll my own?

    I am getting the following error when I try to send an email in my C# program. I am using Visual Studio 2008 on windows 7. I would paste my code first and then the error: using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.IO; using System.Net; using System.Net.Mail; using System.Net.Mime; using System.Net.Sockets; using System.Web; class email_log_files { private string login_username = "my_gmail_id"; private string login_password = "my_gmail_password"; public void send_email() { string src_address = "[email protected]"; string dest_address = "[email protected]"; try { MailMessage email_msg = new MailMessage(); SmtpClient email_client = new SmtpClient(); email_msg.From = new MailAddress(src_address); email_msg.Sender = new MailAddress(src_address); email_msg.ReplyTo = new MailAddress(src_address); email_msg.To.Add(dest_address); email_msg.Subject = "Test"; email_msg.Body = "Body of the message"; NetworkCredential credentials = new NetworkCredential(login_username, login_password); email_client.Credentials = credentials; email_client.Host = "smtp.gmail.com"; email_client.Port = 465; email_client.EnableSsl = true; email_client.Send(email_msg); Console.WriteLine("Message Sent Successfully!!"); Console.ReadLine(); } catch (Exception ex) { Console.WriteLine(ex.Message.ToString()); Console.WriteLine(ex.InnerException); Console.WriteLine(ex.Source); Console.WriteLine(ex.Data); Console.ReadLine(); } } } And the error message is as follows: The operation has timed out. System System.Collections.ListDictionaryInternal Why is it always timing out? I am sure that I have the correct smtp server address and port number for gmail as I have configured my outlook with the same. Any help or ideas?

  • markdown to HTML with customised WMD editor

    - by spirytus
    For my application I customized slightly the way WMD behaves so when user enters empty lines, these are reflected in HTML output as <br />'s. Now I came to a point when I should store it somewhere at backend and so after going thru SO posts for a while I'm not sure what is the best way to do it. I have few options and if you could point out which their pros/cons that would be much appreciated. send to server and store as markdown rather than HTML. To me obvious advantage would be keeping exactly same formatting as user originally entered. But then how can I convert it back to HTML for display to a client? It seems very troublesome to convert it on client side as even if it would be possible what would happen if JS would be disabled? If I wanted to do it on the server, then standard server side implementations of markup to HTML might be resource expensive. Would that be an issue in your opinion? Even if it wouldn't be the case then as I mentioned my WMD implementation is customised and those server side solutions wouldn't probably do the right conversion to markdown anyway and there always would be a risk that something would convert wrong. Send to server as converted HTML. Same as above.. conversion on client side would be difficult, server side same with possibility of getting it wrong. send original markdown and converted HTML and store both. No performance issues related to converting markdown to HTML on client side, nor on server side. Users would have always same markdown they originally entered and same HTML they originally saw in preview (possibly sanitized in php though). It would have to take twice that much storage space though and that is my biggest worry. I tend to lean towards 3rd solution as it seems simplest, but there is a worry of doubled storage space needed for this solution. Please bear in mind that my implementation of WMD is slightly modified and also I'm going with PHP/MySql server side implementation. So apart from 3 options I listed above, are there any other possible solutions to my problem? Did I miss anything important that would make one of the options above better then the rest? And what other pros/cons would apply to each solution I listed? Also how is it implemented on SO? I read somwhere that they using option 3, and so if its good enough for SO would be good enough for me :) but not sure if its true anyway, so how is it done? Also please forgive me, but at least for once I got to say that StackOverflow IS THE BEST DAMN RESOURCE ON THE WEB and I truly appreciate all the people trying to help others here! The site and users here are simply amazing!

  • Change Iframe Content from Cached HTML?

    - by Yang
    Is there any way that I can change the content of iframe from a cached html string? I am not talking about iframe.Attribute["src"] = "url", but rather given a string of html and change the content. An ugly workaround might be saving the html into a file and change iframe src to it. Any other ways? Maybe javascript can help?

Typically I might write an interface like this interface IInterface { MyType ReadMyType(int id); IEnumerable<MyType> ReadMyType(String name); IEnumerable<MyType> ReadMyType(String name, int maxResults); } What would this interface look like after you converted it to WCF?

  • Scribus - disable escaping of text field

    - by ityndall
    Scribus 1.3.3.13 - Ubuntu 64bit I have a scribus document that I'm creating with text fields. I'm using the text fields for code samples, as that appeared to be the only way to have a scrolling text frame. Upon conversion of the document, these text fields get populated with escape characters. Is there any way to disable the escape sequences that are getting populating into these text fields?

    What is the best procedure for storing and retrieving, using native Java serialization, generic objects like ArrayList<String>? Edit: To clarify. When I serialize an object of type ArrayList<String> I'd like to de-serialize to the same type of object. However, I know of no way to cast back to this generic object without causing warnings.

  • Remove leading whitespaces using variable length lookbehind in RegExp

    - by Shizhidi
    Hello, I'm wondering if variable length lookbehind assertions are supported in JavaScript's RegExp engine? For example, I'm trying to match the string "variable length" in the string "[a lot of whitespaces and/or tabs]variable length lookbehind", and I have something like this but it does not go well in various RegExp testers: ^(?<=[ \t]+).+(?= lookbehind) If it's an illegal pattern, what would be a good workaround to it? Thanks!

  • What is the best way to declare sorted association in grails domain classes ?

    - by fabien7474
    It seems that there are two different ways of declaring sorted associations in Grails : Method 1 (see here) using default sort order class Book { String title } class Author { static hasMany = [books : Book] static mapping = { books sort: "title"} } Method 2 (see here) using SortedSet class Book implements Comparable { String title int compareTo(obj) { title <=> obj.title } } class Author { SortedSet books static hasMany = [books : Book] } I am not sure which one to use and what is the difference (if any), pros and cons between using one against the other. I would appreciate any clarification. Thank you
