  • Running an application from an USB device...

    - by Workshop Alex
    I'm working on a proof-of-concept application, containing a WCF service with console host and client, both on a single USB device. On the same device I will also have the client application which will connect to this service. The service uses the entity framework to connect to the database, which in this POC will just return a list of names. If it works, it will be used for a larger project. Creating the client and service was easy and this works well from USB. But getting the service to connect to the database isn't. I've found this site, suggesting that I should modify machine.config but that stops the XCopy deployment. This project cannot change any setting of the PC, so this suggestion is bad. I cannot create a deployment setup either. The whole thing just needs to run from USB disk. So, how do I get it to run? (The service just selects a list of names from the database, which it returns to the client. If this POC works, it will do far more complex things!)

  • [C#] Running elevated applications on user login with UAC?

    - by Alex
    I need to start a program every time the user logs in, but I cannot do this without being met by a UAC dialog asking for permissions for that application. Is there any way to have an application start up on user login without the user having to answer the UAC prompt? I was thinking about running a service, but this would be a last resort. I saw something about an Application Compatibility Toolkit to disable UAC for certain applications, but I feel this is too big of a hassle - even services would be easier to program. I was just wondering if there is an even easier solution I am missing. Thanks in advance.

  • Animate absolutely positioned div, but stop if a condition is true?

    - by Alex
    Hello all, I have a div which I place at the top right-hand corner of a website, absolutely positioned at top: 0px and right : 0px. I want to use jquery's animate function to animate the div left or right a certain amount when a button is clicked, but stop the animation if at anytime, the div's offset to the left or right is less than a certain number. I want to do this to accomodate users who click the left or right buttons more than once, so that the div does not fly out of sight. How does one accomplish this? Below is my relevant css, html, and jquery code: CSS: #scorecardTwo { position:absolute; padding:5px; width: 300px; background-color:#E1E1E1; right:0px; top:0px; display:none; } HTML: <div id = "scorecardTwo"> <span id = "dealHolder"><a href="some/link">some text</a></span> <br /> <span id = "scoreHolder">some text</span> <br /> <button type="button" id="moveLeft">Left</button>&nbsp;<button type="button" id="moveRight">Right</button> </div> jQuery (at the moment): $("#scorecardTwo").fadeIn("slow"); $("#moveLeft").bind("click", function() { $("#scorecardTwo").animate({"right":"+=76%"}, "slow"); // how to stop animation if offset is less than appropriate number? }); $("#moveRight").bind("click", function() { $("#scorecardTwo").animate({"right" : "-=76%"}, "slow"); // how to stop animation if offset is less than appropriate number? });

  • Save or update for FK relationship Sqlalchemy

    - by Alex
    I've googled, but haven't been able to find the answer to this seemingly simple question. I have two relations, a customer and an order. Each order is associated to a single cusomter, and therefore has a FK relationship to the customer table. The customer relation only stores customer names, and I have set a unique constraint on the customer table barring duplicate names. Let's say I create a new order instance and set a customer for the order. Something like: order_instance.customer = Customer("customer name") When I save the order instance, SqlAlchemy will complain if a customer with this name already exists in the customer table. How do I specify to SqlAlchemy to insert into the customer table if a customer with this name doesn't already exist, or just ignore (or even update) to the customer relation? I don't really want to have to check each time if a customer with some name already exists...

  • reorder list elements - jQuery?

    - by Alex
    Hello, I am experimenting with jQuery lately, and I was wondering if it's possible with js or pure jquery to reorder <li> elements. So if I have a silly list like the following: <ul> <li>Foo</li> <li>Bar</li> <li>Cheese</li> </ul> How would I move the list elements around? Like put the list element with Cheese before the list element with Foo or move Foo to after Bar. So is it possible? If so, how? Thanks!!

  • Clojure: I have many sorted maps and want to reduce in order all there values a super maps of keys -> vector

    - by Alex Foreman
    I have seen this but can't work out how to apply it (no pun intended) to my situation. I have a sorted list of maps like this: (note there can be more than two keys in the map) ({name1 3, name2 7}, {name1 35, name2 7}, {name1 0, name2 3}) What I am after is this data structure afterwards: ({:name1 [3,35,0]}, {:name2 [7,7,3]}) Ive been struggling with this for a while and cant seem to get anywhere near. Caveats: The data must stay sorted and I have N keywords not just two.

  • Object initialization sequence in Objective-C

    - by Alex
    Hello everyone. The Cocoa framework has a convention to always call self = [super init] in the init method of an inherited class, because [super init] may return a new instance. What will happen if I do this? @interface MyClass : NSObject /* or any other class */ { int ivar_; } @end @implementation MyClass - (id)init { ivar_ = 12345; if ((self = [super init])) { NSLog(@"ivar_'s value is %d", ivar_); } return self; } @end In the case when [super init] returns a new instance, what will I see in the console? ivar_'s value is 0? I can't think of a way to check this myself, because I don't know which class may return a new instance from its init method. Also, can't seem to find explicit clarification for this scenario in the docs. Could anyone help me out? Thanks!

  • C# - Wait to finish before doing the next task

    - by Alex Ogden
    i have a server application with a richtextbox as the console text basically. The problem is, i have start, restart and stop buttons - But my restart button doesn't work. Heres my code for the restart button: consoletxt("RESTART", "Restarting Server..."); statuslabel1.Text = "Restarting"; statuslabel1.ForeColor = Color.Orange; statuslabel2.Text = "Restarting"; statuslabel2.ForeColor = Color.Orange; command("stop"); //The performclick just starts the server startbtn.PerformClick(); statuslabel1.Text = "Online"; statuslabel1.ForeColor = Color.DarkGreen; statuslabel2.Text = "Online"; statuslabel2.ForeColor = Color.DarkGreen; consoletxt("RESTART", "Restart completed, server online!"); However, the output is this: 2012-04-01 11:32:12 [RESTART] Restarting Server... 2012-04-01 11:32:12 [RESTART] Restart completed, server online! 2012-04-01 11:32:12 [INFO] CONSOLE: Stopping the server.. 2012-04-01 11:32:12 [INFO] Stopping server So, it says that the restart has finished in the text - but it hasn't - all it has done is stop the server. Please can sombody explain to me how to do this properly? Thanks!

  • Replace a DIV with another using effect and set cookie

    - by Alex
    Hi. I've got some complicated requirements and wondered if there's a way to accomplish this via jQuery: User comes to a web page for the first time today and we show DIV_1. After 30 seconds, we dissolve DIV_1 to DIV_2. We set a cookie on the user's machine that expires when s/he returns tomorrow. If the same user returns today, we only show DIV_2. Tomorrow, we repeat the process: The user will see DIV_1 and then it dissolves to DIV_2. How do you accomplish this via jQuery? Thank you.

  • Cast into new Object, Copy values by Property Name

    - by Alex
    Hello, I have the following: Class 1 (Text, State, Level) Class 2 (Text, State, Level, Ident) Is there a way for me to cast an object of Class 2 into into Class 1, and not having to do the usual cast code (Text = c.Text, State = c.State etc.)? Possibly by identifying the property names of each class and copying the value over?

  • How do you make a wrapped div fill the window horizontally?

    - by Alex Parkinson
    I have a div which is contained by another 960px-wide centered div. I'm adding a background to the inner div which should expand all the way to the window's edges horizontally, essentially escaping the boundaries of its container. If I apply a large negative margin and equal amount of padding, this works on the left side, but the right side causes a scroll bar to appear. Does anyone know how I can achieve this without causing scroll bars?

  • Bind an event handler to multiple elements jQuery?

    - by Alex
    Hello all. I've done some experimenting, but can't seem to successfully bind one event handler to multiple elements using jQuery. Here's what I've tried: $('selector1', 'selector2').bind('click', function() { $('someSelector').removeClass('coolClass'); }); I've tested all my selectors, and they are all valid. Is what I'm trying to do even possible? If so, can I do it with .live() as well? Thanks!

  • Removing title from wp_list_cats()

    - by Alex
    I'm trying to remove/replace the title attribute on the category elements used by WordPress. I'm using WordPress 2.9.1, with the following code: <div id="categories"> <h3>Manufacturers</h3> <ul> <?php str_replace("title=\"View all posts filed under ","",wp_list_categories('use_desc_for_title=0&exclude=1,2,3,4,5&title_li=&hierarchical=1')); ?> </ul> </div> From what I had read this method used to work on older versions (I had never tried it though). I really don't want to hack at the interals of WordPress, or have to use a JavaScript hack, for something so straight forward. Any help is appreciated... Update below is what is created from the code above... Manufacturers Featured

  • Is there any way I can use two monitors in the console in Linux?

    - by Alex
    I have recently become the proud owner of two monitors in my workspace. (Ok not owner, but you know what I mean) and I'd like to use both of them at once. Problem is, I much much prefer to use a Linux Server console over a desktop environment. The graphics card on the machine is a GTX295 (don't ask why, it's a long story.) so I essentially have two graphics cards. Each has a DVI output. Is there any way I can get the console to stretch across two screens? Or will I have to install a desktop Ubuntu for this to work?

  • Rails nil can't be coerced into Float

    After adding items, attempting to view my cart leads me to this error: nil can't be coerced into Float with the math line in this method in my line_item model highlighted: def total_price product.price * quantity end line items create action def create product = Product.find(params[:product_id]) @line_item = @cart.add_product(product.id) @line_item.quantity = params[:quantity] view <div id= "text_field"><%= text_field_tag 'quantity' %> </div> <%= button_to 'Add to Cart', line_items_path(:product_id => product) %> This has held me back for a couple days.
