  • For reliable code, NModel, Spec Explorer, F# or other?

    - by ja
    I've got a business app in C#, with unit tests. Can I increase the reliability and cut down on my testing time and expense by using NModel or Spec Explorer? Alternately, if I were to rewrite it in F# (or even Haskell), what kinds (if any) of reliability increase might I see? Code Contracts? ASML? I realize this is subjective, and possibly argumentative, so please back up your answers with data, if possible. :) Or maybe an worked example, such as Eric Evans Cargo Shipping System? If we consider Unit tests to be pecific and strong theorems, checked quasi-statically on particular “interesting instances” and Types to be general but weak theorems (usually checked statically), and contracts to be general and strong theorems, checked dynamically for particular instances that occur during regular program operation (from B. Pierce's Types Considered Harmful, where do these other tools fit? We could pose the analogous question for Java, using Java PathFinder, Scala, etc.

  • C# Spell checker Problem

    - by reggie
    I've incorporated spell check into my win forms C# project. This is my code. public void CheckSpelling() { try { // declare local variables to track error count // and information int SpellingErrors = 0; string ErrorCountMessage = string.Empty; // create an instance of a word application Microsoft.Office.Interop.Word.Application WordApp = new Microsoft.Office.Interop.Word.Application(); // hide the MS Word document during the spellcheck //WordApp.WindowState = WdWindowState.wdWindowStateMinimize; // check for zero length content in text area if (this.Text.Length > 0) { WordApp.Visible = false; // create an instance of a word document _Document WordDoc = WordApp.Documents.Add(ref emptyItem, ref emptyItem, ref emptyItem, ref oFalse); // load the content written into the word doc WordDoc.Words.First.InsertBefore(this.Text); // collect errors form new temporary document set to contain // the content of this control Microsoft.Office.Interop.Word.ProofreadingErrors docErrors = WordDoc.SpellingErrors; SpellingErrors = docErrors.Count; // execute spell check; assumes no custom dictionaries WordDoc.CheckSpelling(ref oNothing, ref oIgnoreUpperCase, ref oAlwaysSuggest, ref oNothing, ref oNothing, ref oNothing, ref oNothing, ref oNothing, ref oNothing, ref oNothing, ref oNothing, ref oNothing); // format a string to contain a report of the errors detected ErrorCountMessage = "Spell check complete; errors detected: " + SpellingErrors; // return corrected text to control's text area object first = 0; object last = WordDoc.Characters.Count - 1; this.Text = WordDoc.Range(ref first, ref last).Text; } else { // if nothing was typed into the control, abort and inform user ErrorCountMessage = "Unable to spell check an empty text box."; } WordApp.Quit(ref oFalse, ref emptyItem, ref emptyItem); System.Runtime.InteropServices.Marshal.ReleaseComObject(WordApp); // return report on errors corrected // - could either display from the control or change this to // - return a string which the caller could use as desired. // MessageBox.Show(ErrorCountMessage, "Finished Spelling Check"); } catch (Exception e) { MessageBox.Show(e.ToString()); } } The spell checker works well, the only problem is when I try to move the spell checker the main form blurs up for some reason. Also when I close the spell checker the main form is back to normal. It seems like it is opening up Microsoft word then hiding the window, only allowing the spell checker to be seen. Please help.

  • Use of qsrand, random method that is not random

    - by Andy M
    Hey everyone, I'm having a strange problem here, and I can't manage to find a good explanation to it, so I thought of asking you guys : Consider the following method : int MathUtility::randomize(int Min, int Max) { qsrand(QTime::currentTime().msec()); if (Min > Max) { int Temp = Min; Min = Max; Max = Temp; } return ((rand()%(Max-Min+1))+Min); } I won't explain you gurus what this method actually does, I'll instead explain my problem : I realised that when I call this method in a loop, sometimes, I get the same random number over and over again... For example, this snippet... for(int i=0; i<10; ++i) { int Index = MathUtility::randomize(0, 1000); qDebug() << Index; } ...will produce something like : 567 567 567 567...etc... I realised too, that if I don't call qsrand everytime, but only once during my application's lifetime, it's working perfectly... My question : Why ?

    I am having a hard time getting video to play in an application that I am working on and I think the answer has to do with the views and view controllers. I have the flow depicted below. When the button is clicked, the audio from the video is playing, but nothing is displayed on screen. Anyone have any ideas? -(IBAction) playMovie { Play Movie Code } ViewController UIScrollView UIView UIButton - (playMovie)

  • Options for small windows network setup without dedicated server?

    - by Mitch
    I'm very weak on networking and hope someone can point me in the right direction: I have written some windows client/server software which incorporates a database which is located on a windows server. I have a test installation running at a customer's office where the server has a static IP address. In this case its easy for the clients to access the database because of the fixed IP address. Also, customers with network servers generally have specialist support staff to set up my software, so its not such a problem for me. However I also need to offer the software to customers who have small offices with less than 10 PCs and no dedicated network server. In this case I want the customer to be able to nominate one PC as the database "server" and install my software and have the clients access it. But in this situation I believe the "server" PC may not have a dedicated IP address. Q1: What is the best way to set this up simply and make it work? Can I reliably reference the "server" by using its name, or is there a way to assign dummy fixed IP addresses? Ideally this needs to be workable on small networks running a mixture of XP/Vista/Windows7 as my target market may well have mixed OSes etc. I guess this would be akin to home networking? Many thanks Mitch

  • How do I setup routing for two companies with different Internet connections on the same LAN?

    - by Clint Miller
    Here's the setup: Two companies (A & B) share office space and a LAN. A 2nd ISP is brought in and company A wants its own Internet connection (ISP A) and company B wants its own Internet connection (ISP B). VLANs are deployed internally to separate the two companies' networks (company A: VLAN 1, company B: VLAN 2, shared VOIP: VLAN 3). With separate VLANs it's simple enough to use separate DHCP servers (or separate scopes on the same server) to assign the default gateway to each company's gateway for their Internet connection. Static routes can be created on each gateway to point traffic destined for the other company's VLAN or the voice VLAN so that all nodes are reachable as expected. However, I think this is a form of asymmetrical routing, right? (The path from node A1 to node B1 is not the same as the path back from node B1 to node A1). Can I set up policy-based routing to correct this? In that case, can I assign the same default gateway to every device on all VLANs and create a routing policy on a L3 switch to look at the source address and forward traffic to the appropriate next hop? In that case, I want the routing logic to go like this: If the destination address is known, forward the traffic (traffic destined for a different VLAN). If the destination address is unknown, forward the traffic to ISP A's gateway if the source address is on VLAN A; or forward the traffic to ISP B's gateway if the source address is VLAN B. Am I thinking about this problem in the correct way? Is there another way to solve this problem that I am overlooking?

  • How do I write a J2EE/EJB Singleton?

    - by Bears will eat you
    A day ago my application was one EAR, containing one WAR, one EJB JAR, and a couple of utility JAR files. I had a POJO singleton class in one of those utility files, it worked, and all was well with the world: EAR |--- WAR |--- EJB JAR |--- Util 1 JAR |--- Util 2 JAR |--- etc. Then I created a second WAR and found out (the hard way) that each WAR has its own ClassLoader, so each WAR sees a different singleton, and things break down from there. This is not so good. EAR |--- WAR 1 |--- WAR 2 |--- EJB JAR |--- Util 1 JAR |--- Util 2 JAR |--- etc. So, I'm looking for a way to create a Java singleton object that will work across WARs (across ClassLoaders?). The @Singleton EJB annotation seemed pretty promising until I found that JBoss 5.1 doesn't seem to support that annotation (which was added as part of EJB 3.1). Did I miss something - can I use @Singleton with JBoss 5.1? Upgrading to JBoss AS 6 is not an option right now. Alternately, I'd be just as happy to not have to use EJB to implement my singleton. What else can I do to solve this problem? Basically, I need a semi-application-wide* hook into a whole bunch of other objects, like various cached data, and app config info. As a last resort, I've already considered merging my two WARs into one, but that would be pretty hellish. *Meaning: available basically anywhere above a certain layer; for now, mostly in my WARs - the View and Controller (in a loose sense).

  • Is there a .NET class that represents operator types?

    - by user323774
    I would like to do the following: *OperatorType* o = *OperatorType*.GreaterThan; int i = 50; int increment = -1; int l = 0; for(i; i o l; i = i + increment) { //code } this concept can be kludged in javascript using an eval()... but this idea is to have a loop that can go forward or backward based on values set at runtime. is this possible? Thanks

  • How does my ASP.NET app get the SMTP settings automatically from web.config?

    - by Ryan
    I noticed that we always just are like: SmtpClient mSmtpClient = new SmtpClient(); // Send the mail message mSmtpClient.Send(mMailMessage); And the only place the credentials are set are in web.config: <system.net> <mailSettings> <smtp> <network host="xxx.xx.xxx.229" userName="xxxxxxxx" password="xxxxxxxx"/> </smtp> </mailSettings> </system.net> So my question is, how does it automagically get them out?

  • StandardOutput.EndOfStream Hangs

    - by Ashton Halladay
    I'm starting a process within my C# application which runs a console application. I've redirected standard input and output, and am able to read a few lines via StandardOutput.ReadLine(). I'm convinced I have the ProcessStartInfo configured correctly. The console application, when started, outputs a few lines (ending with a "marker" line) and then waits for input. After receiving the input, it again outputs a few lines (ending again with a "marker" line), and so on. My intention is to read lines from it until I receive the "marker" line, at which point I know to send the appropriate input string. My problem is that, after several iterations, the program hangs. Pausing the debugger tends to place the hang within a call to StandardOutput.EndOfStream. This is the case in the following test code: while (!mProcess.StandardOutput.EndOfStream) // Program hangs here. { Console.WriteLine(mProcess.StandardOutput.ReadLine()); } When I'm testing for the "marker" line, I get the same kind of hang if I attempt to access StandardOutput.EndOfStream after reading the line: string line = ""; while (!isMarker(line)) { line = mProcess.StandardOutput.ReadLine(); } bool eos = mProcess.StandardOutput.EndOfStream; // Program hangs here. What might I be doing that causes this property to perform so horribly?

  • [ckeditor] apply font size using execCommand

    - by Wiika
    Hi all, var wgetFrame = window.frames[0] wframeDoc = wgetFrame.document; editor.focus(); editor.execCommand('bold'); wframeDoc.execCommand('forecolor',false,'#00ff00'); wframeDoc.execCommand('JustifyCenter', false, null); wframeDoc.execCommand('fontsize', false, 15); (i use the code above as a plugin in CKEditor) bold, forecolor and JustifyCenter , they all rend corectly , the selected text is wrapped by a span element but when applying the fontsize command , the selected goes inside the font element, i know this is correct, but it need it to be inside a span element i need to know why bold, forecolor and JustifyCenter are wrapped by span and fontsize not !! and also if there another way to apply this styles ( ps : i run those commands when ckeditor is initialized, even if the editort doesn't contain any text, when u write the style definied is applied ) CKEDITOR.editorConfig = function(config) { CKEDITOR.addStylesSet('customStyles', [ { name: 'Header 1', element: 'h1' }, { name: 'Header 2', element: 'h2' }, { name: 'Header 3', element: 'h3' }, { name: 'Text', element: 'p' }, { name: 'Left Align', element: 'img', attributes: { 'class': 'ImageLeft'} }, { name: 'Right Align', element: 'img', attributes: { 'class': 'ImageRight'} } ]); }; can i apply editor.execCommand( "Header 1" ); ??

  • CSS dropdowns on touch-based clients. Are pure CSS dropdowns going to become extinct?

    - by Galen
    My company is starting to move toward adding the iPad as a browser i have to test my work on. This got me thinking... Since touch-based clients don't have a :hover state are pure CSS dropdowns going to go away? Then i thought even if you add some javascript to make the menus popup on click... What happens when the menu item (that expands to another menu) is also a link. How do you tell the difference between a click to see the menu or a click to go to that link?

  • Is Domain Anaemia appropriate in a Service Oriented Architecture?

    - by Stimul8d
    I want to be clear on this. When I say domain anaemia, I mean intentional domain anaemia, not accidental. In a world where most of our business logic is hidden away behind a bunch of services, is a full domain model really necessary? This is the question I've had to ask myself recently since working on a project where the "domain" model is in reality a persistence model; none of the domain objects contain any methods and this is a very intentional decision. Initially, I shuddered when I saw a library full of what are essentially type-safe data containers but after some thought it struck me that this particular system doesn't do much but basic CRUD operations, so maybe in this case this is a good choice. My problem I guess is that my experience so far has been very much focussed on a rich domain model so it threw me a little. The remainder of the domain logic is hidden away in a group of helpers, facades and factories which live in a separate assembly. I'm keen to hear what people's thoughts are on this. Obviously, the considerations for reuse of these classes are much simpler but is really that great a benefit?

  • R: How to replace elements of a data.frame?

    - by John
    I'm trying to replace elements of a data.frame containing "#N/A" with "NULL", and I'm running into problems: foo <- data.frame("day"= c(1, 3, 5, 7), "od" = c(0.1, "#N/A", 0.4, 0.8)) indices_of_NAs <- which(foo == "#N/A") replace(foo, indices_of_NAs, "NULL") Error in [<-.data.frame(*tmp*, list, value = "NULL") : new columns would leave holes after existing columns I think that the problem is that my index is treating the data.frame as a vector, but that the replace function is treating it differently somehow, but I'm not sure what the issue is?

  • GUI design techniques to enhance user experience

    - by aku
    What techniques do you know\use to create user-friendly GUI ? I can name following techniques that I find especially useful: Non-blocking notifications (floating dialogs like in Firefox3 or Vista's pop-up messages in tray area) Absence of "Save" button MS OneNote as an example. IM clients can save conversation history automatically Integrated search Search not only through help files but rather make UI elements searchable. Vista made a good step toward such GUI. Scout addin Microsoft Office was a really great idea. Context oriented UI (Ribbon bar in MS Office 2007) Do you implement something like listed techniques in your software? Edit: As Ryan P mentioned, one of the best way to create usable app is to put yourself in user's place. I totally agree with it, but what I want to see in this topic is specific techniques (like those I mentioned above) rather than general recommendations.
