  • Code Colorer Being Used

    - by Sarfraz
    Hello, I visited this site and i really liked the code colorer used by it (apart from that CSS3 article on speech bubbles). I went through the source code of that page but could not find which syntax highlighter is being used there. Does any one have an idea?

  • Admin auto generation

    - by Me-and-Coding
    Hi, I create custom CMS sites and then go ahead for the backend/admin side. Is there any tool out there to automatically create admin side of my sites, for example, based on table relationships or whatever customization we may put in place. PHPMaker seems to claim something like what i ask for but i have not used it. Any tool out there to auto-create admin side or PHPMaker is up to the point? Thanks

  • JavaScript/HTML: How do I display an IMG with a set dimension and if the image is wider or taller th

    - by NickNick
    I have a bunch of images that are guaranteed to have: minimum width = 200px maximum width = 250px minimum height = 150px maximum height = 175px What I want to do is display a consist 200px by 150px rectangle of the image while maintaining scale (no stretching or shrinking). Which means, I might have some overflow. How can I display the image so that it keeps porpotions to the original image size, yet displayed inside a 200x150 px window and hiding any overflow?

  • C# Changing Objects within a List

    - by kwong22
    Hi, I'm having a little problem changing members of an object in a list using a found index. So this is the method I am currently working with: static void addToInventory(ref List<baseItem> myArray, baseItem item, float maxAmount, ref float currentAmount) { if (currentAmount + item.getWeight() <= maxAmount) { Console.WriteLine("item.Quantity = {0}", item.Quantity); if (myArray.Contains(item)) { Console.WriteLine("Item ({0}) already exists", item.Name); int id = myArray.IndexOf(item); myArray[id].Quantity += item.Quantity;//Change occurs in this line, item.Quantity becomes the same as myArray[id].Quantity } else { Console.WriteLine("Adding new item ({0})", item.Name); myArray.Add(item); } currentAmount += item.getWeight(); } else { Console.WriteLine("Inventory full"); } myArray.Sort(); } This method takes several parameters including the inventory/list. I check if the item fits in and if it does, I see if there is another item of the same name in the list, find the index, and add more of the item. However, the quantity of the item added suddenly becomes the same as the quantity of the item in the list. For some reason, this also changes the quantity of the item outside of the list. So therefore, instead of quantities adding up like this: 1, 2, 3, 4, they add up like this: 1, 2, 4, 8. I've just started to learn how to use lists so if there is anything I'm missing, don't hesitate to criticize. Thanks in advance.

  • How to auto-deploy web-app

    - by Frankie
    Hello, I'm trying to make sense on the best way to do automatize a series of things in a row in order to deploy a web-app and haven't yet came up with a suitable solution. I would like to: use google's compiler.jar to minify my JS use yahoo's yui-compressor.jar to minify my CSS access a file and change a string so that header files like "global.css?v=21" get served the correct version deploy the app (sftp, mercurial or rsync?) omitting certain directories like "/userfiles" Can you guys put me on the right track to solve this? Thank you!

  • Getting batch_action functionality in Symfony 1.0

    - by Alex Ciminian
    I'm currently working on a web app written in Symfony. I'm supposed to add an "export to CSV" feature in the backend/administration part of the app for some modules. In the list view, there should be an "Export" button which should provide the user with a csv file of the elements that are displayed (considering filtering criteria). I've created a method in the actions class of the module that takes a comma separated list of ids and generates the CSV, but I'm not really sure how to add the link to it in the view. The problem is that the view doesn't exist anywhere, it's generated on the fly from the data in the generator.yml configuration file. I've posted the relevant part of the file below. I'm new to Symfony, so any help would be appreciated :). Thanks, Alex Update list: display: [id, =name, indemn, _status, _participants, _approved_, created_at] title: Lista actiuni object_actions: _edit: ~ _delete: ~ actions: _create: ~ export_csv: name: Export to CSV action: CSVExport params: id=csvActionSubmit filters: [name, county_id, _status_filter, activity_id] fields: id: name: Nr. crt. ... Thanks to your advice, I've managed to add a button that is linked to my action. The problem is that I also need to send some parameters to the action, because I may not want all the elements - filters may have been used. Unfortunately, the project is using Symfony 1.0, which doesn't support batch_actions. Currently, I'm working around this with Javascript (I parse the DOM to get the numeric ids (from the display table) and then build the link for the button. I really think there could be a better way for this.

  • NLB and Web Deploy

    - by asgerhallas
    I have two webservers in a cluster serving a web application. Using MS Web Deploy to push a new version of the application to one server, and then again to synchronize the files to the other server in the cluster. It seems to be the most ordinary thing to do. But wouldn't there be a problemm, when one server is deployed with the new version, and the other is not yet finished. Will it not cause troubles, when a page loaded with the new version makes a webservice request and the balancer sends the request to the server with the old version? What's the best way to avoid this? I thought about scripting a drainstop of the server, that we deploy to, and make sure only one server is running at a time. But I can't find anyone else, who seems to have written about such a solution. And guess that it doesn't scale very well too. Another solution could be to shut down all servers when updating. But that doesn't seems very clever. Any suggestions?

  • Adding padding to HTML elements - IE, FF, Chrome etc.

    - by NLV
    Hello I've a doubt. Lets consider that we have a div of width 200px. If i add the following the style style="padding-left:10px; padding-right:10px" to the element what happens actually? Will the total width of the div increases to 220px with 10px at the left (for left padding), original width 200px at the middle and 10px at the right (for right padding)? Or will it takes the padding space from the 200px and becomes (10px + 180px + 10px)? Does the above rendering differs for each browser (especially IE and FF)? Thank you NLV

  • JQuery: how to use "delegate" instead of "live"?

    - by JacobD
    I've read countless articles how using the JQuery delegate is much more efficient than using the "live" event. As such, I'm having trouble converting my existing Live code to using Delegate. $("#tabs li:eq(0)").live('click',function(){ //...code }); $('#A > div.listing, #B > div.listing, #C > div.listing').live('mouseover',function(){ // ...code }); When I replace the previous code with what I assume is more efficient delegate code, my page doesn't load. $("#tabs li:eq(0)").delegate('click',function(){ //...code }); $('#A > div.listing, #B > div.listing, #C > div.listing').delegate('mouseover',function(){ // ...code }); Any idea why my delegate code doesn't work? Also, any suggestions on how to make this more efficient? UPDATE: The think part of the problem is that, both "#tabs" and "#A, #B, #C" are't present on the web page at page load. Those attributes are dynamically inserted onto the page with an AJAX call. As such, does that mean I have to use live over delegate?

  • Would you take a paycut [closed]

    - by arinte
    I make 90K doing JEE5 (it is open I can use any tech I want which is nice) but don't like what I am doing to because it is too hw related. I have an offer for 88K and a bonus that would be 10% (almost assured) that I would guess would be paid in the 4th quarter. It is a j2ee, supposed to be moving to jee5 and there are no hw dependencies (banking type work). I think I would be interested, but I have always been told you do not take a pay cut and don't move laterally (go to another job at the same pay). I have been on other interviews but this is the only one that has panned out. Also with the current job there is 401k match, but with the new one there is 401k also and a pension. What would you do?

  • web applications tend to have a admin panel?

    - by ajsie
    i wonder if large web applications like twitter and facebook have admin panels to handle CRUD for users, posts, images, themes and so on just like in CMS like drupal? so programmers have to code the front for the regular users AND back for the administrators? if i develop an web application is it recommended that i also code the admin part? or is it unnecessary since i can handle all directly in mysql and by editing php scripts directly? share your thoughts! thanks

  • Calculating collision for a moving circle, without overlapping the boundaries

    - by Robert Vella
    Let's say I have circle bouncing around inside a rectangular area. At some point this circle will collide with one of the surfaces of the rectangle and reflect back. The usual way I'd do this would be to let the circle overlap that boundary and then reflect the velocity vector. The fact that the circle actually overlaps the boundary isn't usually a problem, nor really noticeable at low velocity. At high velocity it becomes quite clear that the circle is doing something it shouldn't. What I'd like to do is to programmatically take reflection into account and place the circle at it's proper position before displaying it on the screen. This means that I have to calculate the point where it hits the boundary between it's current position and it's future position -- rather than calculating it's new position and then checking if it has hit the boundary. This is a little bit more complicated than the usual circle/rectangle collision problem. I have a vague idea of how I should do it -- basically create a bounding rectangle between the current position and the new position, which brings up a slew of problems of it's own (Since the rectangle is rotated according to the direction of the circle's velocity). However, I'm thinking that this is a common problem, and that a common solution already exists. Is there a common solution to this kind of problem? Perhaps some basic theories which I should look into?

  • how many color combinations in a 24 bit image

    - by numerical25
    I am reading a book and I am not sure if its a mistake or I am misunderstanding the quote. It reads... Nowadays every PC you can buy has hardware that can render images with at least 16.7 million individual colors. Rather than have an array with thousands of color entries, the images instead contain explicit color values for each pixel. A 24-bit display, of course, uses 24 bits, or 3 bytes per pixel, for color information. This gives 1 byte, or 256 distinct values each, for red, green, and blue. This is generally called true color, because 256^3 (16.7 million) He says 1 byte is equal to 256 distinct values. 1 byte = 8 bits. 8^2 bits = 64 distinct colors right ?? It's not adding up right to me. I know it might be something simple to understand, but I don't understand.
