  • Should Service Depend on Many Repositories, or Break Them Up?

    - by Josh Pollard
    I'm using a repository pattern for my data access. So I basically have a repository per table/class. My UI currently uses service classes to actually get things done, and these service classes wrap, and therefore depend on repositories. In many cases my services are only dependent upon one or two repositories, so things aren't too crazy. Unfortunately, one of my forms in the UI expects the user to enter data that will span five different tables. For this form I made a single service class that depends upon five repositories. Then the methods within the service for saving and loading the data call the appropriate methods on all of the corresponding repositories. As you can imagine, the save and load methods in this service are really big. Also, unit testing this service is getting really difficult because I have to setup so many fake repositories. Would it have been a better choice to break this single service apart into a few smaller services? It would put more code at the UI layer, but would make the services smaller and more testable.

  • URL breaking at special character

    - by Josh
    Hello All- I'm having trouble with a URL string in my Web Application. It's using a UNC path similar to \\houtestmachine\common\File1.pdf My problem is when it encounters files that have a # character. I tried doing a string newstring = originalstring.Replace("#", "%23"); but the # is still there in URL (target of a hyperlink) at runtime in the browser. How can I fix this?

  • slidepanel/hover help

    - by Josh
    I'm trying to create a menu navigation system from the top of the page. I want it so when I hover over the link, it drops down (the link drops down; so it'd be as if there was a whole field being hidden beyond the 0px mark) with the related field. I've gotten it to work, somehow but it still isn't right. A few issues are: when I hover over .drop_slide and then if I choose to close it by hovering back over the .drop_slide it does as it's told, which is "slide, slide". I'm interested in rectifying this issue so it doesn't do that, however I just don't know how. The idea is to have multiple links in the .slide, so I need it to be constantly open while the user mouses over the other links. Should this be created in one field? If so, how would I do that with a drop down in mind? Am I approaching this completely wrong? Lol. Should I be researching into .animate? I've been looking at it actually, but I can't get anything to grow negatively. Say; marginTop: -85px or something. ANY help is appreciated, thanks! $(document).ready(function(){ function slide() { $("#panel").slideToggle("slow"); } $(".drop_slide").hover(slide, stop); $("#panel").hover(stop, slide); });

  • Looking for fast "Find in Files" program

    - by Josh McDonald
    I currently have a directory with 98,000 individual archive transaction files. I need to search those files for user input strings and have the option to open the files as it finds them or at the end of the search. I'm using Notepad++ currently and, while functional, it's quite slow. I thought about writing my own, but I am only familiar with .NET and I'm a beginner. Also, I'm not sure how efficient that would be compared to NP++. This tool would be used again and again so the dev time would definitely be worth it if it came to that. Is there some other tool out there that's already developed that would accomplish this?

  • Definition of "lisp form"?

    - by josh
    Hi, What exactly the definition of a "Lisp form"? As far as I know, it's "either an atom or a list that has a symbol as its first element". But then, this (in Scheme) would not be a form: ((lambda () 42)) ;; The answer to Life, the Universe and Everything. Because the first element of the list is itself another list. And after it's evaluated it will be a procedure (not a symbol). I can find several different websites and tutorials talking about Lisp forms, but none which gives a complete and detailed definition. Where can I find one?

  • jQuery passing an array to an AJAX call

    - by Josh K
    I have an array: myarr = []; I'm filling it with some values: myarray['name'] = "Me!"; Now I want to transform that array into a set of Key = Value pairs. I though jQuery would do it automatically, but it doesn't seem to. $.ajax ({ type: "POST", dataType: "text", url: "myurl", data: myarr }); Is there a way to do this or something I'm doing wrong? I get no javascript errors, and no serverside errors other then no POST information at all.

  • MVC and Checkboxes...leaves a bit to be desired

    - by Josh
    Here is my problem. I have a list of models that are displayed to the user. On the left is a checkbox for each model to indicate that the user wants to choose this model (in this case, we're building products a user can add to their shopping cart). The model has no concept of being chosen...it strictly has information about the product in question. I've talked with a few other developers after having gone through and the best I could come up with is getting the formcollection and string parsing the key values to determine whether the checkbox is checked or not. This doesn't seem ideal. I was thinking there would be something more strongly bound, but I can't figure out a way to do it. I tried creating another model that had a boolean property to represent being checked and a property of the model and passing a list of that model type to the view and creating a ActionResult on the controller that accepts a list of the new model / checked property, but it comes back null. Am I just thinking too much like web forms and should just continue on with parsing checkbox values?

  • Bible reference books (PHP / MySQL / Unix)

    - by Josh K
    I'm looking for some nice heavy books to liter around my desk and make it look like I'm a hard core programmer. On the occasion that I might want to look something up they will also need to be useful dependable books. I'm looking for the equivalent bible in PHP, MySQL, and Unix. Should be laid out with some chapters I can actually read, along with having an in-depth reference to that particular subject. I know that the majority of this can be found on Google, but I would prefer it in book form.

  • Is there a (C#) library that will create feeds for Amazon Marketplace Web Services?

    - by Josh Kodroff
    Does anyone know of a library out there (preferably in C#) that will take classes and generate XML or flat files suitable for feeds to Amazon Marketplace Web Services? In other words, I'd like to do something like this: var feed = new AmazonProductFeed(); var list = new AmazonProductList(); var product1 = new AmazonProduct(); product1.Name = "Product 1"; list.Add(product1); var product2 = new AmazonProduct(); product2.Name = "Product 2"; list.Add(product2); feed.Products = list; // spits out XML compliant with Amazon's schema Console.Write(feed.ToXml()); It looks like the only code Amazon provides are wrappers for the web service itself and the directory-based transport utility (AMTU).

  • IE7 preventDefault() not working on skip links

    - by josh
    I currently have skip links that jump to the div ids and was using e.preventDefault() to stop the url from changing when jumping to the element but in IE7 and IE8 it doesn't work at all using e.preventDefault() and if I take it out the url changes to the div the anchor tag contains reference to. Is their any fix or way around this? Here is the code $('body').delegate('a.skiplink-accessible-text', 'click', function (e) { //e.preventDefault(); if (!$.browser.msie) { e.preventDefault(); } var jumpTo = $(this).attr('href'); $('body').find(jumpTo).attr('tabindex', - 1).focus(); }); EDIT: heres a little jsbin example for testing purposes http://jsbin.com/welcome/20846/edit

  • Capturing clicks even when stopPropagation has been called (ie by 3rd party code)?

    - by josh
    I want to detect any click that happens on a page (to close a custom context menu). I'm using jQuery and trying to do $(document).click(function(){ ...close my context menu ... }); However, I'm using some code that calls evt.stopPropagation() in the click handlers for certain elements on the page, and those clicks aren't making it up to my top-level handler. Is there any way of capturing those clicks? Can be jQuery or not jQuery, as long as it works cross-browser.

  • Preventing SQL injecting in a database class

    - by Josh
    I'm building a database class and thought it'd be a good idea to incorporate some form of SQL injection prevention (duh!). Here's the method that runs a database query: class DB { var $db_host = 'localhost'; var $db_user = 'root'; var $db_passwd = ''; var $db_name = 'whatever'; function query($sql) { $this->result = mysql_query($sql, $this->link); if(!$this->result) { $this->error(mysql_error()); } else { return $this->result; } } } There's more in the class than that but I'm cutting it down just for this. The problem I'm facing is if I just use mysql_real_escape_string($sql, $this->link); then it escapes the entire query and leads to a SQL syntax error. How can I dynamically find the variables that need to be escaped? I want to avoid using mysql_real_escape_string() in my main code blocks, i'd rather have it in a function. Thanks.

  • Differentiate Between UITableView Editing States?

    - by Josh Kahane
    I have been looking at trying to differentiate between editing states in my UITableView. I need to call a method only when in editing mode after tapping the edit button, so when you get your cell slide in and you see the little circular delete icons but NOT when the user swipes to delete. Is there anyway I can differentiate between the two? Thanks. EDIT: Solution thanks to Rodrigo Both each cell and the entire tableview has an 'editing' BOOL value, so I loop through all the cells and if more than one of them is editing then we know the whole table is (the user tapped the edit button), however if only one is editing then we know that the user has swiped a cell, editing that individual one, this lets me deal with each editing state individually! - (void)setEditing:(BOOL)editing animated:(BOOL)animated { [super setEditing:editing animated:animated]; int i = 0; //When editing loop through cells and hide status image so it doesn't block delete controls. Fade back in when done editing. for (customGuestCell *cell in self.tableView.visibleCells) { if (cell.isEditing) { i += 1; } } if (i > 1) { for (customGuestCell *cell in self.tableView.visibleCells) { if (editing) { // loop through the visible cells and animate their imageViews [UIView beginAnimations:nil context:nil]; [UIView setAnimationDuration:0.4]; cell.statusImg.alpha = 0; [UIView commitAnimations]; } } } else if (!editing) { for (customGuestCell *cell in self.tableView.visibleCells) { [UIView beginAnimations:nil context:nil]; [UIView setAnimationDuration:0.4]; cell.statusImg.alpha = 1.0; [UIView commitAnimations]; } } }

  • Checking variable from a different class in C#

    - by Josh
    Greetings- I have 2 classes. One is called "Programs" and the other is called "Logs". The class called Programs has public const string m_sEnviron = ""; near the top and I need to check what the m_sEnviron variable is set to through my class called Logs. The variable m_sEnviron will get set from a scheduler called Tidal so how can I check its value from a different class. If this is not the best to do this then please let me know what the better ways are. Thanks in advance. Regards,

  • RegEx - Time Validation ((h)h:mm)

    - by Josh
    /^\d{1,2}[:][0-5][0-9]$/ is what I have. this limits minutes to 00-59. It does not, however, limit hours to between 0 and 12. For similarity and uniformity I would like to do this with RegEx alone if possible. Further-more I would like the first digit to be optional. i.e. 09:30 accepted as well as 9:30. I played around with ranges, but something out of range is always acceptable.

  • Binding TabControl ItemsSource to an ObservableCollection of ViewModels causes content to refresh on

    - by Brent
    I'm creating an WPF application using the MVVM framework, and I've adopted several features from Josh Smith's article on MVVM here... Most importantly, I'm binding a TabControl to an ObservableCollection of ViewModels. This means that am using a tabbed MDI interface that displays a UserControl as the content of a TabItem. The issue I'm seeing in my application is that when I have several tabs and I flip back and forth between tabs, the content is being refersh each time I change tabs. If you download Josh Smith's source code, you'll see that his app has the same problem. For example, click on the "View All Customers" button and scroll down to the bottom the ListView. Next click on the "Create New Customer" button. When you switch back to the All Customer view you'll notice that the ListView scrolls back to the top. If you switch back to the New Customer tab and place your cursor in one of the TextBoxes, then switch to All Customers tab and back, you'll notice that the cursor is now gone. I imagine that this is because I'm using an ObservableCollection, but I can't be sure. Is there any way to prevent the tab's content from refreshing when it receives the focus? EDIT: I found my problem when I ran the profiler on my application. I'm defining a DataTemplate for my ViewModels so it knows how to render the ViewModel when it is displayed in the tab... like so: <DataTemplate DataType="{x:Type vm:CustomerViewModel}"> <vw:CustomerView/> </DataTemplate> So whenever I switch to a different tab, it has to re-create the ViewModel again. I fixed it temporarily by changing my ObservableCollection of ViewModels to an ObservableCollection of UserControls. However, I would really still like to use DataTemplates if possible. Is there a way to make a DataTemplate work?
