Ideas? thxs

• jQuery trigger mouseover function when page loads with the mouse over the element

  - by Gal V

  Hello all, I have an ASP.NET document, with an Image element within it. I created a mouseover function on this image element and it's working fine. The question is: If the mouse is ALREADY over the element when the document loads itself, the mouseover function doesn't trigger (I need to mouseout and then mouseover again in order to trigger it). Is there any way to check in the $(document).ready function if the mouse is already on top of this element? and if yes- trigger the mouseover function. Thanks all!

• Blending transparent textures with depth

  - by l.thee.a

  I am trying to blend textures which have transparent areas: glEnable( GL_TEXTURE_2D ); glBindTexture( GL_TEXTURE_2D, ...); glVertexPointer( 2, GL_FLOAT, 0, ... ); glEnable (GL_BLEND); glBlendFunc (GL_ONE, GL_ONE_MINUS_SRC_ALPHA); glDrawArrays( GL_TRIANGLE_STRIP, 0, 4 ); Unless I add glDisable(GL_DEPTH_TEST), transparent parts of the top textures overwrite everything beneath them (instead of blending). Is there any way to do this without disabling depth? I have tried various blending functions but none of the helped.

• When will NAnt reach version 1.0

  - by sundar venugopal

  I like Nant very much. I do a lot of scripting with NAnt. It is a great little tool. Since NAnt is pre 1.0, when problems occur, I often think if that it is a problem with NAnt itself, but this is not always the case. One funny example: After running the oracle scripts I parsed the log output to make sure there was no problem. I was testing this with a small log file and it was fine. I used the task to load the file contents to a string property and used a regex to search for errors. When I used this script for a large log file, I stopped getting the "build failed" message at the bottom, because I was printing the error messages. Because the "build failed" was hiding at the top, I thought NAnt crashed, but it worked fine. It would be better for NAnt to have a 1.0 release. Any reasons why not?

• OpenLayers Projections.

  - by Jenny

  I can succesfully do: point.transform(new OpenLayers.Projection("EPSG:900913"), new OpenLayers.Projection("EPSG:4326")); To a point that is in the google format (in meters), but when I want to do the reverse: point.transform(new OpenLayers.Projection("EPSG:4326"), new OpenLayers.Projection("EPSG:900913")); to a point that is in 4326 (regular lat/lon format), I am having some issues. Any negative value seems to become NaN (not a number) when I do the transformation. Is there something about the transformation in reverse that I don't understand? Edit: Even worse, when I have no negative values, the coordinates seem off. I am getting the coordinates by drawing a square on the screen, then saving those coordinates to a database and loading them later. I can draw a square near the tip of africa (positive coordinates), and then when it loads it's near the top of africa, in the atlantic ocean. I'm definitely doing something wrong....

• (VB.NET + WPF) Drag + Drop (to allow user sorting) of stackpanel elements within a Scrollviewer?

  - by Matt H.

  I have good model (I think!) for how to allow a user to drag an element in a stackpanel and reposition it to another location within the stackpanel. However, my Stackpanel is placed within a ScrollViewer, like this (generalized): <ScrollViewer> <StackPanel> ....First item ....Second item ....Third item ....Etc. </StackPanel> <ScrollViewer> Here is the problem, I wish to simulate the functionality of programs like word, where if I am dragging selected content (or an object) outside the viewable area, the window will scroll in the direction of the mouse to see more places to drop my nifty little object. ...i.e. If I move the mouse to the top of my ScrollViewer while dragging a stackpanel's contents, I want the scrollviewer to slowly move up so I can see more locations to drop my content. Any suggestions? If you can help me solve this, you will be a godsend!

• OpenGL coordinates question

  - by Chonch

  Hey, I have a simple OpenGL drawing. When the user changes the window's size, I want the drawing to maintain it's aspect ration. I accomplished that by setting the glViewport to the maximum rectangle with the appropriate aspect ration whenever the reshape method is called. My problem is that I want to draw a square that will always remain in the top right corner of the window, no matter what the size or shape of the window is. Right now, that square moves around the screen whenever the window is reshaped. Can anyone please explain how to do this? Thank you,

• Unexpected JAXB error

  - by Mark Lewis

  Hello, From the documentation it's clear I need to use the following to get a simple unmarshalling to occur from my XML file/schema: JAXBContext jc = JAXBContext.newInstance("PackageName"); where PackageName is my package name. I've looked on google for a bit to no avail, to find out why I'm then getting this runtime error: Line:Col[2:142]:cvc-elt.1: Cannot find the declaration of element 'myconfig'. Line:Col[2:142]:unexpected element (uri:"http://www.w3.org", local:"myconfig"). Expected elements are <{}myconfig> Caught UnmarshalException This occurs at the top of all my class files, including the ones the XJC plugin for eclipse created for me (which I then moved out of PackageName.PackageName which it automatically created): package PackageName; so why is this error occurring?

• boost pool_alloc

  - by mr grumpy

  Why is the boost::fast_pool_allocator built on top of a singleton pool, and not a separate pool per allocator instance? Or to put it another way, why only provide that, and not the option of having a pool per allocator? Would having that be a bad idea? I have a class that internally uses about 10 different boost::unordered_map types. If I'd used the std::allocator then all the memory would go back to the system when it called delete, whereas now I have to call release_memory on many different allocator types at some point. Would I be stupid to roll my own allocator that uses pool instead of singleton_pool? thanks

• How to change a UIBarButtonItem in a UINavigationBar

  - by pkulak

  I'm trying to set up a list of items that can be edited. I have a main view, with a UINavigationBar at the top and a UITableView directly under it. I'd like to have my "edit" button change to a "done" button on click, but I can't figure out how to do it. If I could do it in the code (not it interface builder), I could just replace it, but I can't even do that. I've seen some code using [self.navigationItem], but in my case self is a UIView. It also feels a bit odd to be using a UINavigationBar when I don't want navigation (this is one page only), but I want a toolbar with a title and and a button, so I don't think really have a choice.

• SAML Authentication Portal

  - by Alvin Jones

  I'd like to develop a portal similar to what a company like OneLogin (http://www.onelogin.com/) has: The user would login with their login credentials then have links to the web resources that their account is associated with. When they see their resources all they need to do is click on them and they'll be automatically login in (SAML authentication). Are there any open source projects out there that have started on this effort? It would be great if there was something that we could use as a base to build on top of with a friendly license (e.g. MIT). Thanks

• Overlaying image also fades when images change in IE6 jQ slideshow

  - by Hege Rokenes

  I have a pretty basic slideshow fading between images. On top of that slideshow I have a logo that is absolute positioned to stay partly over the slideshow. It works perfectly, but then there is IE6. In IE6 the part of the logo that is overlaying the slideshow also fades when the images change in the slideshow. I really do not want to have half the logo in all the pictures in the slideshow, but that seems to be the only solution right now. Demo of the problem here: http://nonstopas.no/temp/slideshow/ Note that this happens a bit inconsistently (or so it seems), so watch it for a couple of rounds.

• ASP.NET 3.5 Web Site stopped importing System namespace by default

  - by Alexis

  I have a VB Web Site project that has recently (and mysteriously) stopped importing the "System" namespace by default. I'm having to either place a "Imports System" line at the top of each code behind, or preface everything with "System", which is fairly annoying, not to mention redundant. I can't for the life of me figure out how to get the System namespace back to being imported by default. I've already checked to see that WINDOWS\Microsoft.NET\Framework\v2.0.50727\CONFIG\web.config contains the <add namespace="System"/> line--it does. That was my best lead. I'm tearing my hair out. Does anyone have any suggestions?

• WPF: How to get the event when one FrameworkElement comes in contact with other FrameworkElement

  - by Raghav

  I am developing a small application with images and trash box icon on right hand bottom. I have multiple images floating in the main window, and using mouse I can move image from one corner to other corner of window, left, right, top and bottom. I can't figure out how do I catch an event when a image touches and panel (with trash box image), in the right hand corner. Does anybody knows which event or handler to listen? This is not a drag and drop case since my images are floating so no point using drag and drop. Thank you

• UIView Animation: Shrink

  - by Moduspwnens

  I'm looking to have my main view shrink to reveal the next view in the same way the Facebook app's views shrink when you press the top-left button. I already have it working with one of the included animations like this: [UIView beginAnimations:nil context:nil]; [UIView setAnimationCurve:UIViewAnimationCurveEaseInOut]; [UIView setAnimationDuration:1.0]; [UIView setAnimationTransition:UIViewAnimationTransitionFlipFromLeft forView:self.navigationController.view cache:NO]; [self.navigationController popToRootViewControllerAnimated:YES]; [UIView commitAnimations]; I'm fairly well-experienced with the iPhone SDK but haven't spent a lot of time with UIView animations.

• Why doesn't border-radius work properly on text inputs in MobileSafari?

  - by abrahamvegh

  Here is a reference HTML document: <!DOCTYPE html> <html> <head> <style> body { background-color: #000; } input { -webkit-border-radius: 20px; } </style> </head> <body> <input type="text" value="text" /> </body> </html> The border-radius renders fine on Safari/WebKit-based desktop browsers, but on the "MobileSafari" variant, namely the iPhone and iPad browsers, it renders with this strange box, which destroys the illusion of rounded corners when the input is being displayed on top of a differently-colored background.

• JavaScript-like Object in Python standard library?

  - by David Wolever

  Quite often, I find myself wanting a simple, "dump" object in Python which behaves like a JavaScript object (ie, its members can be accessed either with .member or with ['member']). Usually I'll just stick this at the top of the .py: class DumbObject(dict): def __getattr__(self, attr): return self[attr] def __stattr__(self, attr, value): self[attr] = value But that's kind of lame, and there is at least one bug with that implementation (although I can't remember what it is). So, is there something similar in the standard library? And, for the record, simply instanciating object doesn't work: obj = object() obj.airspeed = 42 Traceback (most recent call last): File "", line 1, in AttributeError: 'object' object has no attribute 'airspeed' Thanks, David

• best way to parse plain text file with a nested information structure

• Overriding a function in Emacs Lisp

  - by scrapdog

  I would like to temporarily override the kill-new function. I have a way I want to reimplement kill-new that works in only in certain contexts, but I don't want to reimplement a special version of kill-region on top of that. (kill-new is called from kill-region) Since Emacs Lisp uses dynamic scoping, this should be possible, right? (On the other hand, it seems that this would be an unsafe thing to support, and it might make me a bit nervous knowing that it is possible...) I have experimented with using let and fset, but so far have found no way to get it to work as expected. So, hopefully someone can fill in the blank in the following pseudocode: (defun my-kill-new (string &optional replace yank-handler) (message "in my-kill-new!")) (defun foo () (some-form-that-binds-a-function (kill-new my-kill-new) (kill-region (point) (mark)))) What should some-form-that-binds-a-function be? Or am I barking up the wrong tree?

• Page Footer not showing in Crystal Report

  - by Mike C.

  Hello, I am using Crystal Reports in Visual Studio 2008. I have about 5 pages worth of static text that needs to appear at the top of my report, so I put it in the report header section. I have a page footer section on the page that shows the page number. This does not show, and I suspect it has something to do with the long report header. How can I make the page footer show with a large report header? Edit: The Page Footer is actually appearing once on the last page. The Report Header takes up 5 pages and there isn't a page footer on any of those pages.

• jQuery CSS Custom Flyout Menu Styling Issue

  - by aherrick

  I'm close to nailing this flyout menu I have been working on, just have a couple of current pain points. I'm trying to get left/right padding on my submenu items, as you can see I am not quite there.

• Image Drawing on UIView

  - by user1180261

  I'm trying to create an application where I can draw a lot of pictures at a specific point (determined for each image) on one view. I have a coordinates where I need draw a picture, width and height of it For example: I have 2 billion jpeg's images. for each images I have a specific origin point and size. In 1 second I need draw on view 20-50 images in specific point. I have already tryid solve that in the next way: UIGraphicsBeginImageContextWithOptions(self.previewScreen.bounds.size, YES, 0); [self.previewScreen.image drawAtPoint:CGPointMake(0, 0)]; [image drawAtPoint:CGPointMake(nRect.left, nRect.top)]; UIImage *imagew = UIGraphicsGetImageFromCurrentImageContext(); UIGraphicsEndImageContext(); [self.previewScreen setImage:imagew]; but in this solution I have a very big latency with displaying images and big CPU usage WBR Maxim Tartachnik

• Preserving multi-byte characters in Flex XML object

  - by Dan Petker

  I'm having an issue with the Flex XML object type mangling multi-byte characters (such as Japanese or Chinese characters). The basic setup is this. I'm getting an XML-formatted string from the server, and in that string there can be multi-byte characters. A lot of the time, these characters are in attributes, for example: <example id="foo" name="[some multi-byte characters]"/> Now, when I examine the raw string, the multi-byte characters display just fine. However, as soon as I convert the string to an XML object using the top-level XML() function, all the multi-byte characters become mangled. I've tried setting the XML's encoding by including an <?xml version="1.0" encoding="utf-8"?> element in the XML-formatted string, but this doesn't seem to have any effect on the resulting XML object. Is there a way to get the XML object to respect the encoding of the XML-formatted string and prevent the multi-byte characters from being mangled?

• wheel of fortune collision detection

  - by Andrew

  Hey, I have a wheel segmented into 8 pie pieces, and a picker that is pointing at the currently selected segment (think wheel of fortune). I want to highlight the currently selected segment, and so have started to use Chipmunk to construct the 8 segments, attached to a rotating body, and then the picker that is put in a position to collide with each of the segments. The trick is, how do you allow the picker to pass over top of the segments, while still getting the collision, but not actually colliding and slowing down the wheel? I haven't started down this path yet, but thought this may solve the problem: removing the colliding segment and then putting it back after the picker has started colliding with another segment a bit away (like two segments away). There may be a much simpler solution not even involving Chipmunk that I haven't thought of. Thanks, Andrew
