  • Give a number to return the approximated value of an Enum?

    - by ElektroStudios
    I have this enumeration: Enum Lame_Bitrate kbps_8 = 8 kbps_16 = 16 kbps_24 = 24 kbps_32 = 32 kbps_40 = 40 kbps_48 = 48 kbps_56 = 56 kbps_64 = 64 kbps_80 = 80 kbps_96 = 96 kbps_112 = 112 kbps_128 = 128 kbps_144 = 144 kbps_160 = 160 kbps_192 = 192 kbps_224 = 224 kbps_256 = 256 kbps_320 = 320 End Enum And I would like to return the approximated value of the Enum given a number. For example, if I have the number 190 then I expect to find the more approximated value in the Enum to return the 192 (kbps_192 value of the Enum), if I have the number 196 then again I expect to return the value 192 (not return the next value 224 because is less approximated). Something like this: Private Sub Test() Dim wma_file As String = "C:\windows media audio file.wma" Dim wma_file_Bitrate As Integer = 172 Dim mp3_bitrate_approximated As Integer mp3_bitrate_approximated = Return_Approximated_Value_Of_Enum(wma_file_Bitrate) End Sub private function Return_Approximated_Value_Of_Enum(byval value as integer) as integer return... enum.find(value).approximated... end function Exist any framework method to find the more approximated number given other number in a Enum? I hope you can understand my question, thank you. PS: I prefer a solution using LINQ extensions if can be.

  • How can variadic char template arguments from user defined literals be converted back into numeric types?

    - by Pubby
    This question is being asked because of this one. C++11 allows you to define literals like this for numeric literals: template<char...> OutputType operator "" _suffix(); Which means that 503_suffix would become <'5','0','3'> This is nice, although it isn't very useful in the form it's in. How can I transform this back into a numeric type? This would turn <'5','0','3'> into a constexpr 503. Additionally, it must also work on floating point literals. <'5','.','3> would turn into int 5 or float 5.3 A partial solution was found in the previous question, but it doesn't work on non-integers: template <typename t> constexpr t pow(t base, int exp) { return (exp > 0) ? base * pow(base, exp-1) : 1; }; template <char...> struct literal; template <> struct literal<> { static const unsigned int to_int = 0; }; template <char c, char ...cv> struct literal<c, cv...> { static const unsigned int to_int = (c - '0') * pow(10, sizeof...(cv)) + literal<cv...>::to_int; }; // use: literal<...>::to_int // literal<'1','.','5'>::to_int doesn't work // literal<'1','.','5'>::to_float not implemented

  • Which method should I use to give the perception the computer is thinking in programming?

    - by Roy
    I want to create a simple game like tic tac toe where the human user is playing against the computer. The computer function takes a couple of milliseconds to run but I would like to make the computer take 5 seconds to make a move. Which method should I use? 1) Create two memory threads. One for the computer and one for the human user. When the computer is taking 5 seconds to imitate thinking, the human user thread is paused for 5 seconds. 2) Disable input devices for 5 seconds using timer or dispatchertimer 3) Any better methods you can think of Thanks!

  • How to get rid of a JQUERY APPEND GIve the following code...

    - by nobosh
    Given the following lines of code which is using JQTOUCH: $('#customers').bind('pageAnimationEnd', function(e, info){ if (!$(this).data('loaded')) { $('.loadingscreen').css({'display':'block'}); $(this).append($('<div> </div>'). load('/mobile/ajax/customers/ .info', function() { $(this).parent().data('loaded', true); $('.loadingscreen').css({'display':'none'}); })); } }); How can I get ride of the .append($(' '). It used to be append($('loading') but I didn't need that and now it seems like a waste of processing time to have in the function. Is it possible?

  • How does 301 redirection work across the network? & should I use it if there is a chance we made need to change the resource back to the original URL?

    - by Faust
    I've built a CMS that makes it fairly easy for my client to relocate pages in their site hierarchy. This site has all human-readable and intuitive URLs, so moving a page necessarily means that its URL changes. I am storing records of each resource's past URLs in the data store so that requests for bygone URLs are re-routed to their appropriate successors. I'm warning my clients not to re-arrange the site willy-nilly (for numerous reasons). But nevertheless I suspect there's a chance page moves could get reversed from time to time. So I'm trying to figure out whether 301 or 302 or 307 redirects should be used when serving up pages to requests for out-of-date URLs. I understand the value of using 301 for search engine optimization. But my concern is with this system possibly inadvertently making some pages unavailable to some users QUESTIONS: That is, if the clients move a page at location/URL A to a new location B, then users get the redirect for A to B, and then the clients move the page back to A again, how long can I expect any of those users to keep getting their requests for A redirected to B -- in this case sending them to my friendly 404 page? Is it until an item in their browser history is cleared? Is the redirect somehow cached in routers throughout the internet? How does this work? How long can I expect the 301 redirect to linger out there ?

  • How do I post back information from a webpage that has post-generated content?

    - by meanbunny
    Ok so I am very new to html and the web. Right now I am trying to generate list items on the fly and then have them post back to the web server so I know what the person is trying to obtain. Here is the code for generating the list items: foreach (var item in dataList) { MyDataList.InnerHtml += "<li><a runat='server' onclick='li_Click' id='" + item.Name + "-button'></a></li>"; } Further down I have my click event. protected void li_Click(object sender, EventArgs e) { //How do I determine here which item was actually clicked? } My question is how do I determine which list item was clicked? Btw, the code running behind is C#. EDIT 1 LinkButton link = new LinkButton(); link.ID = "all-button"; link.Text = "All"; link.Click += new EventHandler(link_Click); MyDataList.Controls.Add(link); Then below I have my link_Click event that never seems to hit a breakpoint. void link_Click(object sender, EventArgs e) { if (sender != null) { if (sender.GetType() == typeof(LinkButton)) { LinkButton button = (LinkButton)sender; if (button.ID == "all-button") { } } } } I know this has to be possible I just cant figure out what I am missing. Edit 2 Ok ok I think I know what the problem is. I was trying to add a second list inside of another list. This was causing the whole thing to have problems. It is working now.

  • running php script manually and getting back to the command line?

    - by Simpson88Keys
    I'm running a php script via command line, and it works just fine, except that when it's finished, it doesn't go back to the command line? Just sits there, so I never when it's done... This is the script: $conn_id = ftp_connect(REMOTE) or die("Couldn't connect to ".REMOTE); $login_result = ftp_login($conn_id, 'OMITTED','OMITTED'); if ((!$conn_id) || (!$login_result)) die("FTP Connection Failed"); $dir = 'download'; if ($dir != ".") { if (ftp_chdir($conn_id, $dir) == false) { echo ("Change Dir Failed: $dir<BR>\r\n"); return; } if (!(is_dir($dir))) mkdir($dir); chdir ($dir); } $contents = ftp_nlist($conn_id, "."); foreach ($contents as $file) { if ($file == '.' || $file == '..') continue; if (@ftp_chdir($conn_id, $file)) { ftp_chdir ($conn_id, ".."); ftp_sync ($file); } else ftp_get($conn_id, $file, $file, FTP_BINARY); } ftp_chdir ($conn_id, ".."); chdir (".."); ftp_close($conn_id);

  • How to give new life into a five years old, simple but reliable PHP form?

    - by Sam
    Hi all. I have a script in php 5.2. I want to use a simple form. I found something a programmer made for me about 5 years ago. When I use it, PHP outputs an error now unless I set register_long_arrays = On, then it works fine. On the PHP website, however, it says: Warning This feature has been DEPRECATED as of PHP 5.3.0. Relying on this feature is highly discouraged. It's recommended to turn them off, for performance reasons. Instead, use the superglobal arrays, like $_GET. Should I listen to PHP's warning, or just enable the option and keep using my old form happily? If the former, then how/where do I change this simple form, so it does not rely on the deprecated setting? Your answer is much appreciated. form.htm <html><body> <form method="POST" action="form_sent.php"> ... </form> </body></html> form_sent.php <html><body> <?php $email = $HTTP_POST_VARS[email]; $mailto = "[email protected]"; $mailsubj = "A Form was Sent from Website!"; $mailhead = "From: $email\n"; reset ($HTTP_POST_VARS); $mailbody = "Values submitted from web site form:\n"; while (list($key, $val) = each ($HTTP_POST_VARS)){$mailbody .= "$key : $val\n";} if (!eregi("\n",$HTTP_POST_VARS[email])) { mail($mailto, $mailsubj, $mailbody, $mailhead); } ?> <b>Form Sent. Thank you.</b> </body></html>

    - by Cadu
    Folks, I need your knowledge here. Think about the following sittuation - my app need to set my iphone to vibrate mode on a certain time and get it back to playing sounds mode (for call receiving, sms, email, all common sound notifications) some minutes later. I've already googled that, and didn't find a good, apple accetable way of doing that: http://stackoverflow.com/questions/736047/possible-to-programmatically-open-settings-app-from-iphone http://stackoverflow.com/questions/702319/is-it-possible-to-dynamically-alter-an-iphone-apps-settings-page-in-the-settings http://stackoverflow.com/questions/1141391/display-iphone-application-settings-within-your-application http://stackoverflow.com/questions/335965/how-do-i-launch-my-settings-bundle-from-my-application [This one here is interesting, as fas I as find a way to know what is the key for the settings I'm interested in] http://stackoverflow.com/questions/335965/how-do-i-launch-my-settings-bundle-from-my-application [It mentions I can do that, but does not give an idea of how =(] http://stackoverflow.com/questions/702319/is-it-possible-to-dynamically-alter-an-iphone-apps-settings-page-in-the-settings [If this is true, I wouldn't be able to do what I want...] Does anyone there has an idea of how do I do that via app? Many thanks in advance.

  • Ruby Koans 202: Why does the correct answer give a syntax error?

    - by hlh
    I'm working through the about_classes.rb file in the Ruby Koans, and have hit a brick wall with the "inside_a_method_self_refers_to_the_containing_object" test. Here's the code: class Dog7 attr_reader :name def initialize(initial_name) @name = initial_name end def get_self self end def to_s __ end def inspect "<Dog named '#{name}'>" end end def test_inside_a_method_self_refers_to_the_containing_object fido = Dog7.new("Fido") fidos_self = fido.get_self assert_equal <Dog named 'Fido'>, fidos_self end So, I'm trying to make the first half of the assert_equal evaluate to the second half (fidos_self). When I work it out in irb, fidos_self returns <Dog named 'Fido'>, but I keep receiving a syntax error for that answer. I've seen this similar post: Ruby Koans: Where are the quotes in this return value?, but his solution (putting fido instead of <Dog named 'Fido'>) causes my rake to abort, saying the stack level is too deep. This is driving me nuts. What am I missing here?

  • Google Play: how dev can give (already purchased) app to customer as a gift?

    - by Tertium
    Yes, SO, I know, it's not a "programmer's" question:) But customers sometimes help us (devs) with our code, so we (devs) shold be grateful. I think answer to my question will be useful for all fellow android devs. User has purchased my app. Refund period (15min) is over of course. Now I'd like to return money to him as a gift, because he helped me in testing a little. If I refund the entire order in Checkout-Orders will user keep my app 'purchased'? I mean will he be able to uninstall and install it again from GooglePlay-MyApps and will app be marked "purchased"? Will Google LVL accept him to run the app? I've done such refunds before, but then they called it "Android Market", and refund was 12h, and there were no LVL. Maybe somebody know another way to make a small gift using Google Play?

  • Why does this simple bash code give a syntax error?

    - by Tim
    I have the following bash code, which is copied and pasted from "bash cookbook" (1st edition): #!/bin/bash VERBOSE=0; if [[ $1 =-v ]] then VERBOSE=1; shift; fi When I run this (bash 4.0.33), I get the following syntax error: ./test.sh: line 4: conditional binary operator expected ./test.sh: line 4: syntax error near `=-v' ./test.sh: line 4: `if [[ $1 =-v ]]' Is this as simple as a misprint in the bash cookbook, or is there a version incompatibility or something else here? What would the most obvious fix be? I've tried various combinations of changing the operator, but I'm not really familiar with bash scripting.

  • How: Start an Activity inside a Thread and use finish() to get back.

    - by Kirk Becker
    Hello, I am programming a game on android. I'm using a Thread while calling a Surface View class to update and draw my game. Inside the update I wanted to start an activity based on if the game has just started and this would launch my MENUS. My Thread for the most part.. while (myThreadRun) { Canvas c = null; try { gameTime = System.currentTimeMillis(); c = myThreadSurfaceHolder.lockCanvas(null); synchronized (myThreadSurfaceHolder) { // Update Game. myThreadSurfaceView.onUpdate(); // Draw Game. myThreadSurfaceView.onDraw(c); You can see there where I am updating the game... here is onUpdate(); protected void onUpdate() { // Test if menu needs to be displayed. while (thread.getMenu()) { // Test if menu activity has been started. if (thread.getMenuRunning() == false) { Intent menuIntent = new Intent(this.getContext(), MyMenu.class); ((Activity) cxt).startActivityForResult(menuIntent, 1); thread.setMenuRunning(true); } } I am using a while loop because if I didn't use it the thread just keeps going. Basically I just don't know how to implement my menus using a thread as a game loop. Everywhere I look it seems like that's best practice. In my menu activity I just display the menu layout and a few buttons and when the person wants to start the game it uses finish() to go back to my thread where they play the game. I am very new to this so any insight will be helpful, Thanks

  • (iphone) can i give different intervals between images when animating?

    - by Eugene
    Hi, I'm animating several image as follows. UIImageView* animationView = [[UIImageView alloc] initWithFrame: self.animationViewContainer.bounds]; animationView.animationImages = animationArray; animationView.animationDuration = 0.5; animationView.animationRepeatCount = 5; [animationView startAnimating]; What I'd like to do is, controlling duration between animationImages. For instance, show image1 for 0.3 sec image2 for 0.5 sec.. There must be some way to do this, but hard to find an answer. I've asked the same question here before, but wording of the question wasn't so clear. Thank you

  • How can I give some basic text editing functionality to a firefox plugin?

    - by roddik
    Hello. I'm writing a plugin to Firefox, which is basically a sidebar, that is filled with yaml-formatted information based on what user does on the page (just another web testing solution). I want to enable user to change generated text manually right in the sidebar and: Add code-folding (folding click: \n text: some text to a single line) Add highlighting of registered actions (click, fill and so on) and unregistered actions (syntax errors) How do I do that? Is placing an iframe to the sidebar and trying to do that with html/js the best solution (seen it in a similar one)? As you may have noticed, I'm a newbie in plugin writing, so please excuse if anything.
