  • removing dependancy of a private function inside a public function using Rhino Mocks

    - by L G
    Hi All, I am new to mocking, and have started with Rhino Mocks. My scenario is like this..in my class library i have a public function and inside it i have a private function call, which gets output from a service.I want to remove the private function dependency. public class Employee { public virtual string GetFullName(string firstName, string lastName) { string middleName = GetMiddleName(); return string.Format("{0} {2} {1}", firstName, lastName,middleName ); } private virtual string GetMiddleName() { // Some call to Service return "George"; } } This is not my real scenario though, i just wanted to know how to remove dependency of GetMiddleName() function and i need to return some default value while unit testing. Note : I won't be able to change the private function here..or include Interface..Keeping the functions as such, is there any way to mock this.Thank

  • What is the MVC version of this code?

    - by Ian Boyd
    i'm trying to wrap my head around how to enterprise up my code: taking a simple routine and splitting it up into 5 or 6 methods in 3 or 4 classes. i quickly came up three simple examples of code how i currently write it. Could someone please convert these into an MVC/MVP obfuscated version? Example 1: The last name is mandatory. Color the text box red if nothing is entered. Color it green if stuff is entered: private void txtLastname_TextChanged(object sender, EventArgs e) { //Lastname mandatory. //Color pinkish if nothing entered. Greenish if entered. if (txtLastname.Text.Trim() == "") { //Lastname is required, color pinkish txtLastname.BackColor = ControlBad; } else { //Lastname entered, remove the coloring txtLastname.BackColor = ControlGood; } } Example 2: The first name is optional, but try to get it. We'll add a bluish tint to this "try to get" field: private void txtFirstname_TextChanged(object sender, EventArgs e) { //Firstname can be blank. //Hint them that they should *try* to get it with a bluish color. //If they do enter stuff: it better be not all spaces. if (txtFirstname.Text == "") { //Nothing there, hint it blue txtFirstname.BackColor = ControlRequired; } else if (txtFirstname.Text.Trim() == "") { //They entered spaces - bad user! txtFirstname.BackColor = ControlBad; } else { //Entered stuff, remove coloring txtFirstname.BackColor = SystemColors.Window; } } Example 3 The age is totally optional. If an age is entered, it better be valid: private void txtAge_TextChanged(object sender, EventArgs e) { //Age is optional, but if entered it better be valid int nAge = 0; if (Int32.TryParse(txtAge.Text, out nAge)) { //Valid integer entered if (nAge < 0) { //Negative age? i don't think so txtAge.BackColor = ControlBad; } else { //Valid age entered, remove coloring txtAge.BackColor = SystemColors.Window; } } else { //Whatever is in there: it's *not* a valid integer, if (txtAge.Text == "") { //Blank is okay txtAge.BackColor = SystemColors.Window; } else { //Not a valid age, bad user txtAge.BackColor = ControlBad; } } } Every time i see MVC code, it looks almost like random splitting of code into different methods, classes, and files. i've not been able to determine a reason or pattern to their madness. Without any understanding of they why it's being one some way, it makes no sense. And using the words model, view, controller and presenter, like i'm supposed to know what that means, doesn't help. The model is your data. The view shows data on screen. The controller is used to carry out the users actions And oranges taste orangy. Here's my attempt at splitting things up in order to make the code more difficult to follow. Is this anywhere close to MVC? private void txtFirstname_TextChanged(object sender, EventArgs e) { FirstnameTextChangedHandler(sender, e); } private void FirstnameTextChangedHandler(sender, e) { string firstname = GetFirstname(); Color firstnameTextBoxColor = GetFirstnameTextBoxColor(firstname); SetFirstNameTextBoxColor(firstnameTextBoxColor); } private string GetFirstname() { return txtFirstname.Text; } private Color GetFirstnameTextBoxColor(string firstname) { //Firstname can be blank. //Hint them that they should *try* to get it with a bluish color. //If they do enter stuff: it better be not all spaces. if (firstname == "") { //Nothing there, hint it blue return GetControlRequiredColor(); } else if (firstname.Trim() == "") { //They entered spaces - bad user! return GetControlBadColor(); } else { //Entered stuff, remove coloring return GetControlDefaultColor(); } } private Color GetControlRequiredColor() { return ControlRequired; } private Color GetControlBadColor() { return ControlBad; } private Color GetControlGoodColor() { return ControlGood; } //am i doin it rite i've obfuscated the code, but it's still altogether. The next step in the MVC obfuscation, i gather, is to hide the code in 3 or 4 different files. It's that next step that i don't understand. What is the logical separation of which functions are moved into what other classes? Can someone translate my 3 simple examples above into full fledged MVC obfuscation? Edit: Not ASP/ASP.NET/Online. Pretend it's on a desktop, handheld, surface, kiosk. And pretend it's language agnostic.

  • Code won't exit foreach block

    - by Matt
    I've got the following C# code segment that takes a list, finds objects that are ready to update, then shoves them into a temp list, deletes from the main list, and then goes on its merry way. My issue is that the foreach block, which cycles through my main list, won't exit. TempLog.Clear(); //Ensure TempLog is empty foreach (CLogger ready in PlayerLog) { if (ready.UpdateReady == true) // Record is ready to be updated in database { TempLog.Add(ready); // Add record to templog PlayerLog.Remove(ready); // Remove from playerlog } } <---- Never reaches this point if (TempLog.Count > 0) // Just check that templog isn't empty { new Thread(Update).Start(); // Run update code } I've put heaps of debugging in, and I can watch PlayerLog start at 1, TempLog at 0, then it enters the foreach loop, picks up that the record UpdateReady flag is on, TempLog goes to 1, PlayerLog goes to 0, then it just stops.. No errors, just stops.. Thanks for the help :)

  • Header Guard Issues - Getting Swallowed Alive

    - by gjnave
    I'm totally at wit's end: I can't figure out how my dependency issues. I've read countless posts and blogs and reworked my code so many times that I can't even remember what almost worked and what didnt. I continually get not only redefinition errors, but class not defined errors. I rework the header guards and remove some errors simply to find others. I somehow got everything down to one error but then even that got broke while trying to fix it.

  • Why MySQL multiple-column index is overpopulated?

    - by actual
    Consider following MySQL table: CREATE TABLE `log` ( `what` enum('add', 'edit', 'remove') CHARACTER SET ascii COLLATE ascii_bin NOT NULL, `with` int(10) unsigned NOT NULL, KEY `with_what` (`with`,`what`) ) ENGINE=InnoDB; INSERT INTO `log` (`what`, `with`) VALUES ('add', 1), ('edit', 1), ('add', 2), ('remove', 2); As I understand, with_what index must have 2 unique entries on its first with level and 3 unique entries in what "subindex". But MySQL reports 4 unique entries for each level. In other words, number of unique elements for each level is always equal to number of rows in log table. Is that a bug, a feature or my misunderstanding?

  • frequent updates of a Tomcat application

    - by Erel Segal Halevi
    I have an application that runs on a Tomcat 7 server on a Windows machine. In its current stage, I have to frequently update and fix it. Whenever I need to update the application, I do all this: Build a new war file; Go to the Windows server, stop the Tomcat service; download the file, put it under webapps; Remove the old application folder under webapps; Remove the old application folder under work/Catalina/localhost (otherwise it keeps the old version cached). Restart the Tomcat service. I am sure there is a way to do all this automatically. What is it?

  • Css Multiple background-color

    I'm a novice in Css and it's difficult to search for this specific case on the internet, so I post a question here. I'm working on an existing code base and I see something like this. li { background-color: #000 \9; background-color: rgba(0, 0, 0, 0); } I don't understand the meaning of \9. But it looks to me they are duplicates and I should remove one of them. Could you please explain the \9 and should I remove one of them? Thanks.

  • What is a good architecture for a Lift-JPA application?

    - by egervari
    I was wondering what is the best practice for a JPA model in Lift? I noticed that in the jpa demo application, there is just a Model object that is like a super object that does everything. I don't think this can be the most scalable approach, no? Is it is wise to still do the DAO pattern in Lift? For example, there's some code that looks a tad bloated and could be simplified across all model objects: Model.remove(Model.getReference(classOf[Author], someId)) Could be: AuthorDao.remove(someId) I'd appreciate any tips for setting up something that will work with the way Lift wants to work and is also easy to organize and maintain. Preferably from someone who has actually used JPA on a medium to large Lift site rather than just postulating what Spring does (we know how to do that) ;) The first phase of development will be around 30-40 tables, and will eventually get to over 100... we need a scalable, neat approach.

  • How to initiate an uninstall of a ClickOnce app, from within the app?

    - by dwolvin
    Can I reliably initiate the un-installation of a ClickOnce app, from within the app? In other words, I want to give the user a big "Uninstall Me Now" button on one of the forms. When a user clicks the button, I want to start the windows uninstall process for this app, and perhaps close the app. Reason: We are dead-ending a ClickOnce app and want to make it as easy to remove as it was to install. We don't want to send them down the path to "Add or Remove Programs" and risk them getting lost or distracted. Can this be done reliably?

  • SharePoint 2010 GAC deployment doesn't update

    - by mcnarya
    The following issue just crept up on me. The steps mentioned below had worked just fine until about 2 days ago. When I deploy a update to a solution (of web parts) to a SharePoint 2010 server I don't see the update. The solution does get installed, but from what I can tell the installed web parts are over a month old (nothing new is installed). I do the following steps through PowerShell: retract the solution from the web app remove the solution add the solution install the solution to the web app I have tried restarting the Web App, restarting IIS and also restarting the server. Nothing seems to work. I notice that after I remove the solution it does get removed from the GAC. After I add/install it the solution does reappears in the GAC. Am I missing something? Am I overlooking a step that I should be doing? Something to try?

  • Is this safe on a production server?

    - by Camran
    I have a database application (or search engine) which is called Solr. I connect to it via port 8983. I do this from php code, so I add and remove records from it via php. On my server I have a firewall. I have set this firewall to only allow connections to and from this port (8983) from the ip adress of my own server. In other words, only allow servers IP to access this port. Is that safe? Or am I thinking all wrong here? Will others be able to "simulate" my ip adress and act as the server? This is because otherwise others may add/remove records as they want from their own ip adresses... Thanks

  • Removing Objects From NSMutableArray

    - by Garry
    Hi, I have a NSMutableArray that contains all the calendars on my system (as CalCalendar objects): NSMutableArray *calendars = [[CalCalendarStore defaultCalendarStore] calendars]; I want to remove from calendars any CalCalendar objects whose title does not include the string @"work". I've tried this: for (CalCalendar *cal in calendars) { // Look to see if this calendar's title contains "work". If not - remove it if ([[cal title] rangeOfString:@"work"].location == NSNotFound) { [calendars removeObject:cal]; } } The console is complaining that: *** Collection <NSCFArray: 0x11660ccb0> was mutated while being enumerated. And things go bad. Obviously it would seem you can't do what I want to do this way so can anyone suggest the best way to go about it? Thanks,

  • Determining if a coordinate is on a line

    - by TGCBraun
    I´m coding a little app that allows the user to draw multiple shapes and then remove or resize them. It´s working perfectly on rectangles and ovals, but I´m having issues with lines. Here´s a method that I wrote to find if the clicked spot on the screen is part of a specific line: public boolean containsLocation(int x, int y) { int m = (getY2() - getY()) / (getX2() - getX()); int b = getY() - (m * getX()); if (y == (m * x) + b) { return true; } return false; I´m using the famous y = mx + b formula and replacing y and x to find if the clicked spot is part of the line. The problem is when I click on the screen to remove the line, it only works if I click on the very fist coordinate (x,y) where the line starts. Nothing happens when I click anywhere else along the line. Can anyone shed a light on what I´m doing wrong? Thanks a lot.

  • Zend Framework AjaxContext filters the results and Decorators not removable

    - by Janis Peisenieks
    Ok, since this problem has 2 parts, it will be easier to explain them together. So here goes: I am trying to remove the default decorators from these elements, since I am using a little different way of styling them. But no matter what i do, the DtDDWrapper still shows up. If I try to remove all of the decorators, all of the fields below disappear. public function newfieldAction() { $ajaxContext = $this->_helper->getHelper('AjaxContext'); $ajaxContext->addActionContext('newfield', 'html')->initContext(); $id = $this->_getParam('id', null); $id1=$id+1; $id2=$id+2; $element = new Zend_Form_Element_Text("newTitle$id1"); $element->setOptions(array('escape'=>false)); $element->setRequired(true)->setLabel('Vertiba')->removeDecorator('label'); $tinyelement=new Zend_Form_Element_Text("newName$id"); $tinyelement->setRequired(true)->setOptions(array('escape'=>false))->setLabel('Vertiba')->removeDecorator('label'); $textarea_element = new Zend_Form_Element_Textarea("newText$id2"); $textarea_element->setRequired(true)->setOptions(array('escape'=>false))->setLabel('Vertiba')->removeDecorator('label'); $this->view->descriptionField = "<td>".$textarea_element->__toString()."</td>"; $this->view->titleField = $element->__toString(); $this->view->field = $tinyelement->__toString(); $this->view->id=$id; } The context view script seams to trim my code in one way or another. When I try to put a <td> or a <table> tag in the view script, it just skips the tags. Is there a way to stop this escaping from happening? My view script: id; ?" asdfasdfasdfasd field ? titleField ? descriptionField ? id ?"remove P.S. the code formatting system is barfing at me, could someone please help me with the formatting of the code?

  • jQuery: load refuses to get dynamic content in IE6

    - by user260157
    jQuery refuses to load my dynamic content in IE6. All in FireFox & Safari works fine. Only IE6 is being a pain. When I try the a html with <p>Hello World</p> that works. Properly. But when loading a PHP it doesn't work! As you can see it's doing multiple things. <script type="text/javascript"> // When the document is ready set up our sortable with it's inherant function(s) $(document).ready(function() { // Sort list & amend in database function sortTableMenuAndReload() { var order = $('#menuList').sortable('serialize'); $.post("PLUGINS/SortableMenu/process-sortable.php",order); $("#menuList").load("PLUGINS/SortableMenu/sortableMenu_ajax.php"); } function sortTableOrder() { var order = $('#menuList').sortable('serialize'); $.post("PLUGINS/SortableMenu/process-sortable.php",order); } function sortTableOrderAndRemove(removeID) { $('#listItem_'+removeID).remove(); var order = $('#menuList').sortable('serialize'); $.post("PLUGINS/SortableMenu/process-sortable.php",order); $("#menuList").load("PLUGINS/SortableMenu/sortableMenu_ajax.php"); } $("#menuList > li > .remove").live('click', function () { var removeID = $(this).attr('id'); $.ajax({ type: 'post', url: 'PLUGINS/SortableMenu/removeLine.php', data: 'id='+removeID, success: sortTableOrderAndRemove(removeID) }); }); $("#menuList > li > .publish").live('click', function () { var publishID = $(this).attr('id'); $.ajax({ type: 'post', url: 'PLUGINS/SortableMenu/publishLine.php', data: 'id='+publishID, success: sortTableOrder }); }); $('#new_documents > li').draggable({ addClasses: false, helper:'clone', connectToSortable:'#menuList' }); $("#menuList").droppable({ addClasses: false, drop: function() { var clone = $("#menuList > li#newArticleTYPE1"); $(clone).attr("id","listItem_newArticleTYPE1"); } }); $("#menuList").sortable({ opacity: 0.6, handle : '.handle, .remove', update : sortTableMenuAndReload }); }); </script>

  • Is there a better way to minimize this C# event repetition?

    - by Damien Wildfire
    I have a lot of code like this: public class Microwave { private EventHandler<EventArgs> _doorClosed; public event EventHandler<EventArgs> DoorClosed { add { lock (this) _doorClosed += value; } remove { lock (this) _doorClosed -= value; } } private EventHandler<EventArgs> _lightbulbOn; public event EventHandler<EventArgs> LightbulbOn { add { lock (this) _lightbulbOn += value; } remove { lock (this) _lightbulbOn -= value; } } // ... } You can see that much of this is boilerplate. In Ruby I'd be able to do something like this: class Microwave has_events :door_closed, :lightbulb_on, ... end Is there a similar shorter way of removing this boilerplate in C#?

  • How to warn for the use of unset variables in a korn shell script

    - by Lepu
    Is there any way to throw errors or warnings in a korn shell script to prevent the use of unset variables ? Let's assume I have a temporary folder that I want to remove. TEMP_FILES_DIR='/app/myapp/tmp' rm -Rf $TEMP_FILE_DIR #notice the misspelling How to prevent this kind of mistakes before they actually happen? I know the script should check for file existence and empty string before attempting to remove, this is just a silly example to illustrate a mistake that could have been avoided with some warnings. I don't know if this feature exists in ksh. If it does exist, how do you turn it on?

  • Is it so bad to have heaps of elements in your DOM?

    - by alex
    I am making a real estate non interactive display for their shop window. I have kicked jCarousel into doing what I want: Add panels per AJAX Towards the end of the current set, go and AJAX some new panels and insert them This works fine, but it appears calling jQuery's remove() on the prior elements cause an ugly bump. I'm not sure if calling hide() will free up any resources, as the element will still exist (and the element will be off screen anyway). I've seen this, and tried carousel.reset() from within a callback. It just clears out all the elements. This will be running on Google Chrome on Windows XP, and will solely by displaying on LCD televisions. I am wondering, if I can't find a reasonable solution to remove the extra DOM elements, will it bring my application to a crawl, or will Chrome do some clever garbage collecting? Or, how would you solve this problem? Thanks

  • AppFabric serialization problem.

    - by jandark
    I am trying cache a class instance with AppFabric but it return class instance with empty members. The reason is DataContract Attribute. My class is marked with [Serializable] and [DataContract(Name = "TestClass", Namespace = "CustomNameSpace.TestClass")] attributes. Problem solving if I mark all properties with DataMember or remove DataContract attribute. But I do not want to remove DataContract attributte because of other serialization needs (such as json or something else) Or I do not want to add DataMember attribute to other classes. (a lot of) Do you have any idea to solve that problem ? Thanks.

  • Undocumented feature of Dictionary?

    - by Jon
    Dictionary<string, int> testdic = new Dictionary<string, int>(); testdic.Add("cat", 1); testdic.Add("dog", 2); testdic.Add("rat", 3); testdic.Remove("cat"); testdic.Add("bob", 4); Fill the dictionary and then remove the first element. Then add a new element. Bob then appears at position 1 instead of at the end, therefore it seems to remember removed entries and re-uses that memory space? Is this documented anywhere because I can't see it on MSDN and has caused me a day of grief because I assumed it would just keep adding to the end.

  • Jquery Help : Draggable to Sortable and then back to draggable again.

    - by Swamy g
    I have a pool of items in the drag list which is connected to a sortable using connectToSortable option. Now I want to remove some items from this sort list and move them back to the drag list. Sort of like an undo. Suppose the user moves some 5 items to sort list and decides he/she wants only 4 items, and decides to just drag the unwanted item from the sortlist TO the drag list. How do I accomplish this WITHOUT adding a "remove" link in the sort list. Thanks a lot. For more information please refer to http://the-stickman.com/web-development/javascript/jquery-dropping-items-from-a-draggable-list-to-a-sortable-list/

  • Is there a way to cut and paste or clone CSS from one element to another using JQuery?

    - by Jared Christensen
    I have a situation where I'm wrapping an image with a span and I want to remove all the CSS from the image and apply it to the span. Is there a way to do this with JQuery? JQuery: $(img).wrap('<span />'); Style Sheet: img { border: 5px solid red; padding: 10px; … } I would like do to do this with out editing the HTML or CSS. For example adding a class to the image would not work very well in my situation. I need a way to truly remove the CSS from one element and place it on another.
