• Why would GDI+ colours vary based off whether a tooltip is visible?

  - by dlanod

  I'm displaying a bitmap using GDI+. After loading the bitmap from a DLL resource I set the background colour (blue - #0000FF) to transparent using TransparentBlt. On Windows Vista and later this works as expected. However, on a Windows XP system we're testing on this only works when any tooltip (e.g. the "title" property in IE, or Windows Explorer's tooltip shown when hovering the mouse over a file, etc) is displayed. The rest of the time the background colour is still blue. Has anyone encountered this before, or know of a way to stop this occurring and for the blue to be properly made transparent?

• Pre-load audio files at the client-side for later use

  - by awj

  I'm building an online test which implements audio (mp3) using the native audio player (i.e. non Flash-based). The test shows one question at a time and loads each subsequent question asynchronously. Some questions have an accompanying audio file, others don't, and the audio files can be several MB in size. So what I'm hoping to do is to preload the audio files client-side at the start of the test and then move these into place when the relevant question comes up. So far I've tried loading an audio file into a QuickTime player, then when that question comes up I use jQuery's clone(true) method to copy this into a part of the page which is displayed. However, when I do this the QuickTime player has to reload the audio file from source. Same is true for Windows Media Player. Does anyone have any suggestions as to how I can preload the audio client-side and then call it forward when needed?

• GWT tries to load a deleted module

  - by Dmitry

  I am using Eclispe with Google plugin for AppEngine and GWT. Recently I created a test GWT module, but eventually it has been deleted from the project and I can not find any sign of it in the project now. However, whenever I run the web app locally, I get in console the following message: Loading modules com.piq.exemity.Test [ERROR] Unable to find 'com/XXXXXX/Test.gwt.xml' on your classpath; could be a typo, or maybe you forgot to include a classpath entry for source? Has anyone got any idea where it can be hiding?

• How to get arc4Sin() output into label/NSString

  - by Moshe

  I'm trying to take the output of arc4sin and put it into a label. (EDIT: You can ignore this and just post sample code, if this is too irrelevant.) I've tried: // Implement viewDidLoad to do additional setup after loading the view, typically from a nib. - (void)viewDidLoad { [super viewDidLoad]; NSString *number = [[NSString alloc] stringWithFormat: @"%@", arc4random() % 9]; label.text = number; } I've created an IBOutlet for "label" and connected it. What's wrong here?

• Implementing 1 to n mapping for ORM c++

  - by karan

  I am writing a project where I need to implement a stripped down version of an ORM solution in C++. I am struck in implementing 1-n relationships for the same. For instance, if the following are the classes: class A { ... } class B { ... std::list<A> _a_list; ... } I have provided load/save methods for loading/saving to the db. Now, if I take the case of B and the following workflow: 1 entry from _a_list is removed 1 entry from _a_list is modified 1 entry is added to _a_list Now, I need to update the db using something like "b.save()". So, what would be the best way to save the changes, i.e, identify the additions, deletions and updates to _a_list.

• user notification while waiting

  - by user315445

  I am writing a simple win forms app in C#. There is a method call in my method which loads files but is taking a while to respond. Below is the method call Directory.GetFiles(selectedFolder, "*.xml", SearchOption.AllDirectories); I want to notify this to users. Is there a way to show them that file loading is in progress? I want a simplest way. I suppose Splash screen is too costly for my app.

• Jquery toggle should expand after Page reload

  - by James123

  I wrote below code for Collapse/Expand some section. It is working fine. Finally If I click "Save" button and I am re-loading page again in asp.net. So then sections are going default Colleapse again. I need them back to expand. How can I do that? $(function() { $('tr.subCategory') .css("cursor", "pointer") .attr("title", "Click to expand/collapse") .click(function() { $(this).siblings('.RegText-' + this.id).toggle(); }); $('tr[@class^=RegText-]').hide().children('td'); })

• Exception "Illegal attempt to associate a collection with two open sessions" when saving object

  - by Alex

  I am using CastleProject ActiveRecord and I use lazy load feature of this ORM. In order to make lazy load work, it is required to create SessionScope. I do this in Program.cs: public static SessionScope sessionScope; private static void InitializeActiveRecord() { ActiveRecordStarter.Initialize(); sessionScope = new SessionScope(); } This works fine for loading, however, when I try to save my objects, I get an exception saying "Illegal attempt to associate a collection with two open sessions". I guess this is due to the fact that I created one session myself. How to avoid this exception?

• alternatives to eval for running remote code.

  - by Raynos

  Are there any alternatives to using eval to immediatly run remote & trusted javascript code. function load(filePath) { var o = $.ajax({ url: filePath, dataType: 'html', async: false }); eval(o.responseText); } load("somePath"); // run a function that relies on the code from o.responseText being loaded doSomethingWithCode(); I'm aware that synchronous loading of javascript is adviced againts. But if there is no choice are there any cross browser alternatives for the use of eval above. [Edit] To clarify in more detail the code being loaded is a self executing function. Which needs to execute before doSomethingWidthCode. It's also being loaded from the server on the same domain hence its trusted.

• Convert my aspx page to png image

  - by Izabela

  I am generating an aspx page which then I need to convert to png and store it somewhere. A similiar situation with mine was asked before here but got still no response. I tried also the code that the Swapnil Fegade has asked but the code is looping continually making request to loading page and no conversion is actually being done. I found some solutions on the web also but they require WebBrowser control which i understood can be used in windows form but i am building a web project. Can you give me any hint or suggest any article that shows a full example doing this task. Thank you guys in advance.

• navigation framework in silverlight 3 skipping constructor when usercontrol is of a derived type

  - by tarren

  Hi: I am using the NavigationFramework in Silverlight 3, and am running into issues where the constructor of the UserControl in the xaml I am loading is not being called, and I believe this is because the UserControl in the xaml I am calling is actually derived from another user control. I have stepped through the debugger with specific break points and the constructor is being ignored completey. I have MyWindowBlue which is of type uctrlBaseMyWindow. The constructor for uctrlBaseMyWindow is being called when the xaml is 'navigated to' but the constructor for MyWindowBlue is being ignored. This is not the case if I add the user control via markup directly. Anyone else have this issue? The code I am using to navigate to the MyWindowBlue is this.MyContentFrame.Navigate(new Uri("/Controls/uctrlMyWindowBlue.xaml", UriKind.Relative)); Has anyone run into this or could offer any help? Thanks

• Problem using AJAX with a Java Applet

  - by diglettpotato

  I currently have a Java Applet which contains a method callfromjs(). Javascript calls this method from the applet so that I don't have to deal with the clunky applet GUI, and then I can create the responses on the DOM easily from javascript. The problem is that the browser hangs while first loading the applet. To get around this, I figured I could use AJAX. The AJAX calls a PHP file which contains callfromjs(). The problem is that the request returns because it's PHP, and it doesn't wait for callfromjs() to retrieve the content. On to my questions: Is there a better way to handle this? If this method seems ok, how can I force the request not to return until the javascript is finished calling the method from the applet?

• Where is the best place to run initialization code for a UITabBarController?

  - by bobobobo

  I have a UITabBarController in my application. I have to perform some customization to the NIB file using code the first time a view embedded in that UITabBarController gets loaded. When applicationDidFinishLaunching occurs, the UITabBarController's views apparently are not loaded -- if I try to modify the view controllers inside a tab bar that the tab bar is to load in applicationDidFinishLaunching, then those changes are ignored. I'm assuming this is because the tab bar didn't finish loading yet. So, I need a good place to put code that will run immediately after a tabbar is fully ready -- i.e. after it has loaded all the views from their respective nib files. I'm finding the only place I can do this is to track the first time viewDidAppear on each individual view controller. Note I can't use viewWillAppear because I need the value of tabBarController.selectedIndex to be accurate, and it is only actually updated after viewDidAppear gets fired, not when viewWillAppear gets fired.

• Java Archtecture Decision !!

  - by santiagobasulto

  Hi everybody! I'm developing a medium Java app, and i'm facing a small problem due to my lack of expirience. I've a custom DAO, which gets "Article" objects from the DataBase. I've the Article class, and the DAO has a method called getArticle(int id), this method returns an Article. The Article has a Category object, and i'm using lazy loading. So, when i request for an Article Category (Article a = new Article(); a.getCategory();) the Article class gets the Category from the DAO and then returns it. I'm now thinking to cache it, so when i request multiple times to an Article's category, the database is only queried one time. My question is: where should i put that cache? I can put it on the Article class (in the DTO), or i can put it on the DAO class. What do you say? Thanks!

• How to estimate memory need by XPathDocument for a specific xml file

  - by bill seacham

  Is there any way to estimate the memory requirement for creating an XpathDocument instance based on the file size of the xml? XpathDocument xdoc = new XpathDocument(xmlfile); Is there any way to programmatically stop the process of creating the XpathDocument if memory drops to a very low level? Since it loads the entire xml into memory, it would be nice to know ahead of time if the xml is too big. What I have found is that when I create a new XpathDocument with a big xml file, an outofmemory exception is never fired, but that the process slows to a crawl, only 5 Mb of memory remains a available and the Task Manager reports it is not responding. This happened with a 266 Mb xml file when there was 584 Mb of ram. I was able to load a 150 Mb file with no problems in 18. After loading the xml, I want to do xpath queries using an XpathNavigator and an XpathNodeIterator. I am using .net 2.0, xp sp3.

• Why does some images not display in different browsers?

  - by RePRO

  I've unreal problem. I have a site, where are displaying images over an classical <img> tag. All images are loading from the database, where is URL column of the image. My problem is that three of ten images are not display. But if I open the source code and click at the URL of the image, I can see image. In source code is some looks like (just for a simple example): <img src = "http://some.image/1.jpg" alt = "description" height = "140" width = "187" /> But the biggest snag is that Opera displays all images correct, but just in FF, IE, Chrome are mentioned problems. I can not provide a screenshots, because the pages are a bit perverse. How can I show the site where the problem is? Or some advice? Thank you.

• Update Message on ASP.NET ModelPopupExtender

  - by John

  Hi, I have a form in a MS AJAX ModalPopup Extender, which is in a UpdatePanel (for async loading). Everything works as expected. There is one thing that I am trying to do but not sure how to do it. On form submission, there is server side validation on top of client side validation. My question is: what is the best way to display validation error messages if any? It would be ideal if the messages could be written to the popup asynchronously so that the popup is still there. If this is not possible, I am thinking of displaying the messages using the JavaScript alert box. Any insight and suggestions are greatly appreciated. John

• Visual Studio Config File Editor - Not Formatting

  - by Ian

  Hi All, My VS 2008 seems to be acting a bit weird and the solution is eluding me. The problem is that if I open a config file; app.config or web.config, this looks and behaves as a plain text document. I have no formatting, no coloring, no intellisense and no collapsible or expandable regions. I have reset all setting and restored default file associations. If I go into the setting menu, Text Editor, XML, formatting I see an error "An error occurred loading this property page" Has any one seen this before and have you go a solution. Thanks

• Javascript - Jquery .load() and setInterval() issue.

  - by Joe

  Let's say I do this: $("#content").load(...); Within what I'm loading some javascript is included: var myCounter = 0; var myInterval = setInterval(function(){ myCounter++; $("#counter-display").html("Count: "+myCounter); }); For an unknown reason, if I reload the content with $("#content").load(...); - myInterval is now being called twice. I tried doing something like: if (myInterval !== undefined){ //dont set interval again } However, it doesn't work. Does anyone know any method so that myInterval is cleared on .load, without needing to put the javascript outside of the loaded file?

• ASP.NET impersonations?

  - by asaf

  Hi! I have a aspx file that suppose to write to a file in the server while loading. On the local machine it works fine, but when i deploy it to a live server it gives me an exception "Access to the path 'd:\DZHosts\LocalUser\asafz83\www.asafz83.somee.com\lala.htm' is denied." WHen i asked my serverAdmin for the reason - he told me to remove any impersonation from my web.config file. Well, my web.config file doesn't contain any impersonation, so i'm really confused: What can i do in order for this sealy-stupid application to work? thanks!

• Apache 2.2 / Win7 - slow or not responsive

  - by joey

  My configuration - Windows 7 x64, Php 5.3, Apache 2.2.15, latest Mysql. When loading pages from localhost, the response time shown by firebug is more 530ms for the main 'index.php' file, sometimes the connection is reset. It's painfully slow. I googled the problem and found a workaround - switch off and on again a win service called BFE - base filtering engine. Then everything works like a lightning but xdebug doesn't work in netbeans. Why is this response time so long? Can you think of any other solution than BFE toggling? joey33

• How to keep Hibernate mapping use under control as requirements grow

  - by David Plumpton

  I've worked on a number of Java web apps where persistence is via Hibernate, and we start off with some central class (e.g. an insurance application) without any time being spent considering how to break things up into manageable chunks. Over time as features are added we add more mappings (rates, clients, addresses, etc.) and then amount of time spent saving and loading an insurance object and everything it connects to grows. In particular you get close to a go-live date and performance testing with larger amounts of data in each table is starting to demonstrate that it's all too slow. Obviously there are a number of ways that we could attempt to partition things up, e.g. map only the client classes for the client CRUD screens, etc., which would have been better to get in place earlier rather than trying to work it in at the end of the dev cycle. I'm just wondering if there are recommendations about ways to handle/mitigate this.

• Is the method addSubview of NSView inherently slow? (Cocoa OSX)

  - by Michael Minerva

  I am trying to speed my gui that loads very slow slow when I am loading a large project (the gui is a representation of groups and sub groups and is made up of many views). During this process I was looking at how long certain code segments take to execute and I have found that a call to addsubview is taking between 10 and 20 milliseconds most of the time. The subview I was looking at is a disclosure button. I am wondering if this method is just inherently slow or is their some other factor at work here? Is the time it takes to add the subview dependent on the complexity of the subview or is that not a factor? Also, is there some other method that can be used to add a subview that might be faster?

• Crystal Reports and WMF image

  - by Eve

  I have a problem with inserting a vector graphics (WMF) into report (Crystal Reports v10.5 from Visual Studio 2008). The image is static, inserted by choosing "Insert Picture" during report design in VS. The problem is that it displays differently (size and aspect ratio) on machines with different operating systems and screen resolutions. Converting to bitmap isn't possible beacause loss of the quality of print isn't acceptable. I thought about dynamic loading of the image, but in this version of CR. I don't see a possibility to set dynamic graphic location in picture properties. Is there any way to solve this problem?

• Android WebView not respecting scaling percentage on physical devices...

  - by fiXedd

  I have a WebView which I'm trying to have scale to a certain percent on loading the page. The iPhone version of this software uses the HTML meta-tag: <meta name="viewport" content="width=320, initial-scale=0.95, maximum-scale=2.0, user-scalable=1"> Since Android's WebView doesn't seem to respect that tag I hard-coded the percent using setInitialScale(). However, the WebView is just flat-out ignoring this method call. No matter what number I put in there it shows at 100%. Ideas? Update: It's working fine in the emulator, it's only failing on my Droid (Motorola) and my G1 (HTC).
