  • C++ game loop example

    - by David
    Can someone write up a source for a program that just has a "game loop", which just keeps looping until you press Esc, and the program shows a basic image. Heres the source I have right now but I have to use SDL_Delay(2000); to keep the program alive for 2 seconds, during which the program is frozen. #include "SDL.h" int main(int argc, char* args[]) { SDL_Surface* hello = NULL; SDL_Surface* screen = NULL; SDL_Init(SDL_INIT_EVERYTHING); screen = SDL_SetVideoMode(640, 480, 32, SDL_SWSURFACE); hello = SDL_LoadBMP("hello.bmp"); SDL_BlitSurface(hello, NULL, screen, NULL); SDL_Flip(screen); SDL_Delay(2000); SDL_FreeSurface(hello); SDL_Quit(); return 0; } I just want the program to be open until I press Esc. I know how the loop works, I just don't know if I implement inside the main() function, or outside of it. I've tried both, and both times it failed. If you could help me out that would be great :P

  • jquery mouseleave issue when moving too slow

    - by David
    Hello. I am using the jQuery mouseenter and mouseleave events to slide a div down and up. Everything works well except for the mouseleave which doesn't appear to fire ONLY if the mouse of moved off of the div quite slowly. If i move the mouse at a relatively normal or fast speed then it works as expected. Can anyone explain this or provide any info on how to get around this? Code: $(document).ready(function() { $('header').mouseenter(function() { $(this).stop().animate({'top' : '25px'}, 500, function() { $(this).delay(600).animate({'top' : '-50px'}, 500); }); }). mouseleave(function(e) { var position = $(this).position(); if (e.pageY > position.top + $(this).height()) { $(this).stop().delay(600).animate({'top' : '-75px'}, 500) ; } }); });

  • Anyway to find out the current Windows is in lock mode?

    - by David.Chu.ca
    I have a windows application written in VS 2005. The application makes queries against to sql database in a timer cycle every 2 minutes. If there any data changes, the window will be refreshed with new data. If the user leaves the window, the windows will be automatically locked after a while. There is no sense to keep querying data in ever 2 minutes when the windows is locked; therefore I would like to stop the query when lock is on so that the network data trafic will be reduced and also saves the current windows resources such as memory and CPUs. I am not sure if there is any way to find out the current windows is locked? Not sure if there is any Windows APIs for this purpose if no .Net classes available? My project is in .Net 2.0 and all users are in Windows XP.

  • How can I change a connection string, or other app settings, at test time in Visual Studio 2008?

    - by David
    I need to test a class library project in VS. This project, itself, does not have a web.config file, but the classes do on the web server to which it's deployed. I access these like this: ConfigurationManager.ConnectionStrings["stringname"].ConnectionString; Can I adjust these strings while running unit tests in VS? Should I have considered a different design method to avoid this problem?

  • php clean up regex

    - by David
    hey can i clean up a preg_match in php from this: preg_match_all("/(".$this->reg['wat'].")?(".$this->reg['wat'].")?(".$this->reg['wat'].")?(".$this->reg['wat'].")?(".$this->reg['wat'].")?(".$this->reg['wat'].")?(".$this->reg['wat'].")?/",$value,$match); to look like this: preg_match_all("/ (".$this->reg['wat'].")?

(".$this->reg['wat'].")? /",$value,$match); right now each space, it counts as a ling break so it wont return any finds when searching. but it just looks cleaner and easier to read is why i ask you know. i was looking for one of those letters to add after the closing "/" in the regex. thanks

  • Hidden links are still clickable on the Android browser

    - by David
    I've got a contextual menu that appears when a button is clicked. This menu has some links and after some seconds is hidden again. The problem is that after the menu has disappeared the links are still there. They are not shown but are clickable and the green border appears. And after some seconds they disappear. I've tryied many ways of hiding the menu: display: none, visibility: hidden, width: 0, height: 0, jquery hide, jquery fadeout... but none worked. Also hidding the links. Does anyone have a idea about what's happening? With the rest of the browsers it works without problem Thanks

  • Regex "or" Expression

    - by David
    This is probably a really basic question, but I can't find any answers. I need to match a string by either one or more spaces OR an equals sign. When I split this string: 9 x 13 = (8.9 x 13.4) (89 x 134) with ( +) I get: part 0: 9 x 13 = (8.9 x 13.4) part 1: (89 x 134) When I split it with (=) I get: part 0: 9 x 13 part 1: (8.9 x 13.4) (89 x 134) How can split by BOTH? Something like: (=)OR( +) Edit: This does not work(=)|( +) Test it here: http://myregexp.com/ under "split".

  • converting a form from text to textarea

    - by David Cook
    I have a form created to pull PHP values into my database. I created the form with all type="text" constructions. What follows is the code that used to set up the input of data and confirmed that it is functional. <label>About Me: <input type="text" name="BIO_info"/></label> I converted the input to a textarea and adjusted some parameters for proper display. Unfortunately, it has broken the ability for the script to function. What follows is the code I wrote to convert and store from a text area input. <label for="BIO_info" style=" margin-bottom: 500px; margin-top: 2000px; ">About Me: <textarea name="BIO_info" rows="20" cols="60" style="resize: none; overflow-y: hidden;vertical-align:middle;"></textarea> <p> I would appreciate any suggestions.

  • conflicting cygwin and windows path

    - by David
    if my windows path looks like this: c:\ruby\bin;c:\cygwin\bin then when i go into cgywin and enter "ruby" it will execute the ruby from c:\ruby\bin, failing to find the ruby installed in my cygwin. I have to exclude that path so cygwin would execute the one from /usr/bin. But i need those 2 paths, since i want to run ruby in windows too. Anyway to have cygwin have its own path and not inherit those in windows? thanks.

  • How can I save a screenshot directly to a file in Windows?

    - by David
    In Windows XP, one can press Alt-PrintScreen to copy an image of the active window, or Ctrl-PrintScreen to copy an image of the full desktop. This can then be pasted into applications that accept images: Photoshop, Microsoft Word, etc. I'm wondering: Is there a way to save the screenshot directly to a file? Do I really have to open Photoshop simply to paste an image, then save it?

  • Web developement learning env

    - by David Oneill
    I am currently learning Ruby on Rails. I currently do all my development on my laptop. However, I know in all "real world" situations, I will be connecting to a dedicated server that will hold the site. So here is my question: what are the pros and cons of developing on the machine I use vs running the website on a separate server?

  • Problem with modifying a page with ajax, and the browser keeping the unmodified page in cache.

    - by David Lawson
    Hey there, I have a situation where my page loads some information from a database, which is then modified through AJAX. I click a link to another page, then use the 'back' button to return to the original page. The changes to the page through AJAX I made before don't appear, because the browser has the unchanged page stored in the cache. Is there a way of fixing this without setting the page not to cache at all? Thanks :)

  • And now for a complete change of direction from C++ function pointers

    - by David
    I am building a part of a simulator. We are building off of a legacy simulator, but going in different direction, incorporating live bits along side of the simulated bits. The piece I am working on has to, effectively route commands from the central controller to the various bits. In the legacy code, there is a const array populated with an enumerated type. A command comes in, it is looked up in the table, then shipped off to a switch statement keyed by the enumerated type. The type enumeration has a choice VALID_BUT_NOT_SIMULATED, which is effectively a no-op from the point of the sim. I need to turn those no-ops into commands to actual other things [new simulated bits| live bits]. The new stuff and the live stuff have different interfaces than the old stuff [which makes me laugh about the shill job that it took to make it all happen, but that is a topic for a different discussion]. I like the array because it is a very apt description of the live thing this chunk is simulating [latching circuits by row and column]. I thought that I would try to replace the enumerated types in the array with pointers to functions and call them directly. This would be in lieu of the lookup+switch.

  • using empty on inaccessible object with __isset and __get

    - by David
    <?php class Magic_Methods { protected $meta; public function __construct() { $this->meta = (object) array( 'test' => 1 ); } public function __isset($name) { echo "pass isset {$name} \n"; return isset($this->$name); } public function __get($name) { echo "pass get {$name} \n"; return $this->$name; } } $mm = new Magic_Methods(); $meta = empty($mm->meta->notExisting); var_dump($meta); echo "||\n"; $meta = empty($mm->meta); var_dump($meta); The snippet above does not work as expected for me. Why would the first empty() ommit the __isset? I get this: pass get meta bool(true) || pass isset meta pass get meta bool(false) I would expected identical results or another pass at the __isset, but not a direct call to __get. Or am I missing something here?

  • How do I make an iframe 100% height of a containing div in Firefox?

    - by David
    I'm having some trouble figuring out how to extend an iframe to 100% of it's container element in Firefox and IE (it works fine in Chrome). From searching around, it makes sense that there has to be a width specified on the containing div (and possibly body and html as well). However, I have done that, and the iframe is still not extending. Do all of the parent divs have to have a specified width and position for this to work, or just the containing parent? Any fix for this would be greatly appreciated! Here's what I have: <!DOCTYPE html> <html> <head> <style> html, body {margin:0; padding:0; height:100%} #container {width: 1000px; min-height: 550px; position: relative} #smallContainer {position:relative} /*no width specified*/ #iframeContainer {height: 100%; position: relative} #iframe {height: 100%; width: 100%; display: block} </style> </head> <body> <div id="container"> <div id="smallContainer"> <div id="iframeContainer"> <iframe id="iframe" src="foo.com"></iframe> </div> </div> </div> </body> </html>

  • Proper structure for dependency injection (using Guice)

    - by David B.
    I would like some suggestions and feedback on the best way to structure dependency injection for a system with the structure described below. I'm using Guice and thus would prefer solutions centered around it's annotation-based declarations, not XML-heavy Spring-style configuration. Consider a set of similar objects, Ball, Box, and Tube, each dependent on a Logger, supplied via the constructor. (This might not be important, but all four classes happen to be singletons --- of the application, not Gang-of-Four, variety.) A ToyChest class is responsible for creating and managing the three shape objects. ToyChest itself is not dependent on Logger, aside from creating the shape objects which are. The ToyChest class is instantiated as an application singleton in a Main class. I'm confused about the best way to construct the shapes in ToyChest. I either (1) need access to a Guice Injector instance already attached to a Module binding Logger to an implementation or (2) need to create a new Injector attached to the right Module. (1) is accomplished by adding an @Inject Injector injectorfield to ToyChest, but this feels weird because ToyChest doesn't actually have any direct dependencies --- only those of the children it instantiates. For (2), I'm not sure how to pass in the appropriate Module. Am I on the right track? Is there a better way to structure this? The answers to this question mention passing in a Provider instead of using the Injector directly, but I'm not sure how that is supposed to work. EDIT: Perhaps a more simple question is: when using Guice, where is the proper place to construct the shapes objects? ToyChest will do some configuration with them, but I suppose they could be constructed elsewhere. ToyChest (as the container managing them), and not Main, just seems to me like the appropriate place to construct them.

  • Trouble with go tour crawler exercise

    - by David Mason
    I'm going through the go tour and I feel like I have a pretty good understanding of the language except for concurrency. On slide 71 there is an exercise that asks the reader to parallelize a web crawler (and to make it not cover repeats but I haven't gotten there yet.) Here is what I have so far: func Crawl(url string, depth int, fetcher Fetcher, ch chan string) { if depth <= 0 { return } body, urls, err := fetcher.Fetch(url) if err != nil { ch <- fmt.Sprintln(err) return } ch <- fmt.Sprintf("found: %s %q\n", url, body) for _, u := range urls { go Crawl(u, depth-1, fetcher, ch) } } func main() { ch := make(chan string, 100) go Crawl("http://golang.org/", 4, fetcher, ch) for i := range ch { fmt.Println(i) } } The issue I have is where to put the close(ch) call. If I put a defer close(ch) somewhere in the Crawl method, then I end up writing to a closed channel in one of the spawned goroutines, since the method will finish execution before the spawned goroutines do. If I omit the call to close(ch), as is shown in my example code, the program deadlocks after all the goroutines finish executing but the main thread is still waiting on the channel in the for loop since the channel was never closed.

  • Server RAID 5 failed...all I have left is my compiled website

    - by David Murdoch
    Yesterday, 2 of the 3 drives in my dev server's RAID 5 decided to die on me (with no warning). I've come to grips with the fact that my data is most likely lost unless I shell out some major bucks for professional data-resortoration. People, don't be an idiot like me and treat your RAID as a data backup! Luckily I published the site about 4 hours before my files went bye-bye. Is there any way to run some [magical] program to restore my compiled site to their original files? Also: I develop on one machine with the files stored on the server...is there some visual studio 2010 web cache on my local machine (the one that didn't crash) that I may be able to use?

  • T-SQL get SELECTed value of stored procedure

    - by David
    In T-SQL, this is allowed: DECLARE @SelectedValue int SELECT @SelectedValue = MyIntField FROM MyTable WHERE MyPrimaryKeyField = 1 So, it's possible to get the value of a SELECT and stuff it in a variable (provided it's scalar, obviously). If I put the same select logic in a stored procedure: CREATE PROCEDURE GetMyInt AS SELECT MyIntField FROM MyTable WHERE MyPrimaryKeyField = 1 Can I get the output of this stored procedure and stuff it in a variable? Something like: DECLARE @SelectedValue int SELECT @SelectedValue = EXEC GetMyInt (I know the syntax above is not allowed because I tried it!)

  • mysql select where count = 0

    - by david parloir
    Hi, In my db, I have a "sales" table and a "sales_item". Sometimes, something goes wrong and the sale is recorded but not the sales item's. So I'm trying to get the salesID from my table "sales" that haven't got any rows in the sales_item table. Here's the mysql query I thought would work, but it doesn't: SELECT s.* FROM sales s NATURAL JOIN sales_item si WHERE s.date like '" . ((isset($_GET['date'])) ? $_GET['date'] : date("Y-m-d")) . "%' AND v.sales_id like '" . ((isset($_GET['shop'])) ? $_GET['shop'] : substr($_COOKIE['shop'], 0, 3)) ."%' HAVING count(si.sales_item_id) = 0; Any thoughts?
