• How to find dynamically loaded modules (the static ones) programatically in windows

  - by Ryan Rohrer

  I'm trying to port the unix utility ldd to windows, because dependency walker and cygcheck don't quite give me the usage I'm looking for. (also for the learning experience) Ive been looking all over MSDN, for a windows API that lists dll dependencies of an executable, or even the storage format in the complied exe (just to filter it out), but I've been unable to find anything. If anyone knows what API call windows uses for listing modules to load, or what patterns I can search for in an executable to find modules to load, please help me out :) thanks! -note: I'm not looking to profile for dynamic modules, just list the ones that are required at runtime

• C++ and virtual methods overriding

  - by silent

  Sorry for this stupid question, but I can't find an answer by myself, I'm too new in C++ :( class DBObject : public QObject { ... protected: virtual QString tableName() { return ""; }; }; class DBUserObject : public DBObject { ... protected: virtual QString tableName() { return "profiles"; }; }; And I have this code in parent: bool DBObject::load(quint32 id) { QString query = QString("select %1 from %2 where id = :id") .arg(fieldList().join(",")) .arg(tableName()); <--- here is trouble ... } So I'm trying to execute: DBUserObject user; user.load(3); But in result I have a query with empty table name cause tableName() method returns empty string. Why not "profiles"?

• Why is order important in moving from tab to tab programmatically (and new in 1.8.10

  - by Bruce

  Hi folks, Up until I updated to jquery-ui-1.8.10 (already using jQuery 1.5), the following code has worked as expected: case 'baseeditor': $('#tab1').html(responseText).fadeIn(500, function() { ... load the contents of the tab and stuff... }); $("#prolearn").tabs("select",1); break; case ... The tab is fueled and then focus is moved from tab0 (from where the ajax call is initiated) to tab1. Now, that code won't work, but this version does: case 'baseeditor': $("#prolearn").tabs("select",1); $('#tab1').html(responseText).fadeIn(500, function() { ... load the contents of the tab and stuff... }); break; case ... Can someone explain the difference - have I just been lucky getting away with my original version? Thanks/Bruce

• How to set Main Inerface in xCode programatically

  - by Tom Tallak Solbu

  I am using Apples MultipleDetailViews http://developer.apple.com/library/ios/#samplecode/MultipleDetailViews/Introduction/Intro.html for template as a source for my iPad app. The template is using a splitviewController in the interface builder (MainWindow). In the iPhone/iPad Deployment info of the target, MainWindow is set as the "Main Interface". I want my app to also run on iPhone. This means I need to load a different xib when the app is run on an iPhone. I must then remove "MainWindow" from "Main Interface" because the app will crash when I load on an iPhone due to the splitViewController. The AppDeleagte of the template look like this: - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]]; self.window.rootViewController = self.splitViewController; [self.window makeKeyAndVisible]; } If I remove "Main Window" from "Main Interface", how do I then need to change the APpDelegate, or maybe I need to change the MainWindow.xib to also work for iPhone?

• Embed external website inside a page

  - by jasongullickson

  I'd like to load something from website B into a page on website A and contain the functionality of website B within a container on website A. I tried doing this using a div and jQuery's load() method but I run into cross-domain-scripting issues (I think, it works with a local file but not a remote URL). I also tried using an iframe but strange things happen (for example, when a link is clicked in the "contained" website B, it reloads the entire browser, losing the content of website A). I've read about some server-side ways of handling this (and it may just come to that) but ideally I want something completely client side, JavaScript and HTML. Any ideas?

• asp.net web form Cutom Router Handler

  - by jparram

  I am using a custom route handler for a webforms application. I am using routes to determine localization. ie: if the url has es or fr in the route it will load either spanish or french resources. for example: www.someroute/es/checkstuff/checkstuff.aspx will load: www.someroute/checkstuff/checkstuff.aspx with the spanish resources. I am configuring the custom routes in global.asax via: protected void Application_Start(object sender, EventArgs e) { RegisterRoutes(RouteTable.Routes); } public static void RegisterRoutes(RouteCollection routes) { foreach (var value in _customRoutes) { routes.Add(value.RouteName, new Route(value.Route, new CustomRouteHandler(value.ResolvedRoute))); } } where _customroutes is a list of routes. Is there a way to do this with some kind of pattern matching so I can avoid adding a specific route for each page in the application. While I know I could use a t4 template to generate the routes, I guess I am looking for a dynamic way to create the list

• How do you make the script wait for the status of an Ajax get request before continuing?

  - by codeninja

  Basically what I'm doing is checking for the existence of an object, if it's not found, the script will try to load the source file using getScript. I only want to check this once though then return true or false to the function that calls fetch() fetch:function(obj){ ... isReady = false; $.getScript(obj.srcFile,function(){ isReady=true; warn("was able to load object "+key); }); return isReady; } but return kicks in before the script loads =/ later the script is loaded but the function returned false. This is the beauty of asynchronous I suppose... What's the best way to handle this... Maybe I could check again at some other point if the object exists? Or maybe there's a better way to do this where I dont have to potentially lock the browser?

  Hey, I'm a .net developer mostly, doing something small in C++ so im having a little trouble. I'm loading another C++ dll using hInst = LoadLibrary(TEXT("mydll.dll")); and I came to realize that this looks for the dll I'm trying to load in 'C:\' or in 'system32'. Can someone show me how to load the dll from the current directory (without knowing what the current directory is ahead of time) ?? I know I should be using something like GetFullPathName but I'm having a little trouble getting it to work on my own...

• android google maps my location

  - by windblow

  I have google maps activity where i would like to get my location but im facing NullPointerException... locManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE); locManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0, this); Location location = locManager.getLastKnownLocation(LocationManager.NETWORK_PROVIDER); System.out.println("loaded4"); myPoint = new GeoPoint((int)(location.getLatitude()*1E6),(int)(location.getLongitude()*1E6)); System.out.println("loaded5"); I am able to get "loaded4" but not "loaded5" So NullPointer cause is between them. I also tried to use GPS_PROVIDER but it didnt work out. Yes i have all permissions in manifest. Map is able to load in if im not searhing for my loacation. Is it possible its NullPointer because before that i load some other coordinates in same class ? Maybe its emulator fault ? I can give extended code if needed.

• add parameter to links on page using jquery

  - by Priyo

  How do I add let's say something like ajax=1 to all links on my page with jquery. I will also need to check if the url has existing parameters. for example "http://mysite.com/index.php?pl=132" will have to become "http://mysite.com/index.php?pl=132&ajax=1" Also, if the link does not have any parameters, for example "http://mysite.com/index.php", it will become "http://mysite.com/index.php?ajax=1" I want to load the jquery script on document ready so all links are changed on page load. Thanks.

• How to make my WPF application as FAST as Outlook

  - by Raul Otaño

  The commons WPF applications take some time for loading medium complex views, once the view is loaded it works fine. For example in a Master - Detail view, if the Detail view is very complex and use different DataTemplates take some seconds (2-3 seconds) for load the view. When i open the Outlook application, for instance, it renders complex views and it is relative much more fast. Is there a way for increase the performance of my WPF application? Maybe a way for not loading the template's data every time that change the "master" item, and load it only one time in the app time live? i will appreciate any suggestion.

• How can code in a JavaScript file get the file's URL?

  - by dalbaeb

  I need to dynamically load a CSS stylesheet into a page that's on a different domain. How can I get the complete URL of the JS file to use in the href attribute of the stylesheet? For instance, here is the structure: http://bla.com/js/script.js http://bla.com/css/style.css I want to dynamically load the stylesheet into a page http://boo.net/index.html. The problem is, I don't know the bla.com bit in advance, just the fact that the stylesheet is in ../css/ relative to the JS file. The script is, of course, included on index.html. jQuery's fine too.

• How can I refresh a page via jQuery and ensure that there's a connection?

  - by Steve

  Hi! I toyed around with .load() and .ajax(), but i didn't get to an end. Here's what I need: Everey minute the function shall check if it can load a certain page. if the connection succeeds, I want the page to be refreshed, if not, nothing shall happen, the script shall retry later. I'm using the jQueryTimers plugin. this is my code so far: //reload trigger $(document).everyTime('60s', 'pagerefresh', reloadPage, 0, true); //refresh function function reloadPage() { $.ajax({ url:'index-1.php', type:'HEAD', success: location.reload(true) }) } I have no idea how to tell jQ what I want. any hint appreciated.

Can any one point out what may cause the problem?

• Using Linq to filter parents by their children

  - by Nick L

  Having some problems with my Silverlight app (with RIA services) filtering my results. The idea is on the client I set up the EntityQuery and its filters and call load. However this isn't working for me. Heres my code. public void FireQuery(string filterValue) { EntityQuery<Parent> query = m_ParentDomainContext.GetParentQuery(); query = query.Where(p => p.Children.Any(c => c.Name.Contains(filterValue))); m_ParentDomainContext.Load(query, Query_Completed, null); } Compiles just fine, however, runtime I get "Query operator 'Any' is not supported." Exception. Does anyone know of a good way to filter like this? Again, I'm looking for a way to set this up on the client.

• How to change the opacity (alpha, transparency) of an element in a canvas element after it has been

  - by Joe Lencioni

  Using the HTML5 <canvas> element, I would like to load an image file (PNG, JPEG, etc.), draw it to the canvas completely transparently, and then fade it in. I have figured out how to load the image and draw it to the canvas, but I don't know how to change its opacity once it as been drawn. Here's the code I have so far: var canvas = document.getElementById('myCanvas'); if (canvas.getContext) { var c = canvas.getContext('2d'); c.globalAlpha = 0; var img = new Image(); img.onload = function() { c.drawImage(img, 0, 0); } img.src = 'image.jpg'; } Will somebody please point me in the right direction like a property to set or a function to call that will change the opacity? Thanks!

• Creating non-framework calsses in CakePHP

  - by Affian

  I'm making a tournament manager in CakePHP 1.3 and I have a tournament controller which is fine but I want to implement a interface that can be used to define how a tournament runs. the controller needs to load a concrete class that implements the TournamentStyle interface that defines how the tournament works. At the end of a round the TournamentStyle is used to calculate the scores and winners and generate the next round of matches. That gives me a .php file for the interface and other files for the various styles. My question is: where would I put these files and how would I load them into my tournament controller?

• Force a page cache of Ajax content

  I have a page that is an search where the results are loaded via ajax. It then lists products on a page and you can click to view each product. I'd like to change this page where after you view a product if you click "back" on your browser it'll load the cache instead of forcing the user to search again. How can I achieve this? I currently have.... header('Cache-Control: private, max-age:3600'); header('Expires: '.gmdate('D, d M Y H:i:s \G\M\T', time() + 3600)); and it doesn't load the cache
