• FLex MouseEvent doesn't fire when Mouse stays over element

  - by Tomaszewski

  Hi, i'm trying to make a scrollable box, when a mouse enters and STAYS on "wrapper"'s area, "pubsBox" moves 10 pixels to the left. <mx:Canvas id="wrapper" height="80" width="750"> <mx:HBox id="pubsBox" horizontalGap="10" height="80" width="100%" /> </mx:Canvas> My problem is that I'm not sure how to make the MouseEvent.MOUSE_OVER work, to recognize that the mouse is still ON the area and so pubsBox should continue to move 10 pixels to the left every second. I understand that i have to use a Timer, but what I'm concerned about is the fact that I can't get Flex to recognize that the mouse is still OVER "wrapper" and continue firing the event. Any ideas?

• Executing AJAX scripts within an AJAX response

  - by KcYxA

  Hi there, I'm having trouble using AJAX page updates along with other AJAX scripts. During a normal page load, the AJAX scripts (picture scrolling and picture thumbnails) work fine. But when I update a page with AJAX, these scripts (usually loaded in the header of the initial page load) stop working. I am wondering if this is specific to these scripts and I need to look into them deeper to resolve/re-write or if I am missing something more generic in combining AJAX page updates with AJAX scripts the returned code relies on. Embedded javascript runs fine. Thanks for your ideas! PS: The scripts I am using are from www.dynamicdrive.com are: 1) stepcarousel (http://www.dynamicdrive.com/dynamicindex4/stepcarousel.htm) and 23) thumbnailviewer (http://www.dynamicdrive.com/dynamicindex4/thumbnail.htm) from the

• .NET Debugging - System.Threading.ExecutionContext.runTryCode

  - by moogs

  We have this bug that only appears 30% of the time for the Release build. Opening the crash dump in WinDbg (snipped "!analyze -v" output): FAULTING_IP: +4 00000000`00000004 ?? ???

• iPad UIColor Saturation Issues

  - by Carter Allen

  I am trying to draw a UIColor on the screen of a view-based app, and I am trying to do so using HSB. It is absolutely necessary for me to use HSB in this case. I can create a UIColor object with any S value from 0.0f to 0.75f, but past that the numerical changes have no effect on the actual saturation displayed. I need it to be 1.0f, but it is still using 0.75f. Any ideas on why it is doing that, and how I can make it work?

• Python: Why is IDLE so slow?

  - by Adam Matan

  Hi, IDLE is my favorite Python editor. It offers very nice and intuitive Python shell which is extremely useful for unit-testing and debugging, and a neat debugger. However, code executed under IDLE is insanely slow. By insanely I mean 3 orders of magnitude slow: bash time echo "for i in range(10000): print 'x'," | python Takes 0.052s, IDLE import datetime start=datetime.datetime.now() for i in range(10000): print 'x', end=datetime.datetime.now() print end-start Takes: >>> 0:01:44.853951 Which is roughly 2,000 times slower. Any thoughts, or ideas how to improve this? I guess it has something to do with the debugger in the background, but I'm not really sure. Adam

• Matplotlib and WSGI/mod_python not working on Apache.

  - by Luiz C.

  Everything works as supposed to on the Django development server. In Apache, the django app also works except when matplotlib is used. Here's the error I get: No module named multiarray. Exception Type: ImportError Exception Value: No module named multiarray Exception Location: /usr/share/pyshared/numpy/core/numerictypes.py in <module>, line 81 Python Executable: /usr/bin/python Python Version: 2.6.4 From the python shell, both statements work: import numpy.core.multiarray and import multiarray. Any ideas? Thanks As I'm looking over the numpy files, I found the multiarray module, which has an extension of 'so'. My guess, is that mod_python is not reading these files.

• How to propagate spring security login to EJBs?

  - by tangens

  Context I have a J2EE application running on a JBoss 4.2.3 application server. The application is reachabe through a web interface. The authentication is done with basic authentication. Inside of the EJBs I ask the security context of the bean for the principal (the name of the logged in user) and do some authorization checks if this user is allowed to access this method of the EJB. The EJBs life inside a different ear than the servlets handling the web frontend, so I can't access the spring application context directly. Required change I want to switch to Spring Security for handling the user login. Question How can I propagate the spring login information to the JBoss security context so I can still use my EJBs without having to rewrite them? Ideas and links I already found a page talking about "Propagating Identity from Spring Security to the EJB Layer", but unfortunatelly it refers to an older version of Spring Security (Acegi) and I'm not familiar enough with Spring Security to make this work with the actual version (3.0.2).

• if cookies are disabled, does asp.net store the cookie as a session cookie instead or not?

  - by Erx_VB.NExT.Coder

  basically, if cookeis are disabled on the client, im wondering if this... dim newCookie = New HttpCookie("cookieName", "cookieValue") newCookie.Expires = DateTime.Now.AddDays(1) response.cookies.add(newCookie) notice i set a date, so it should be stored on disk, if cookies are disabled does asp.net automatically store this cookie as a session cookie (which is a cookie that lasts in browser memory until the user closes the browser, if i am not mistaken).... OR does asp.net not add the cookie at all (anywhere) in which case i would have to re-add the cookie to the collection without the date (which stores as a session cookie)... of course, this would require me doing the addition of a cookie twice... perhaps the second time unnecessarily if it is being stored in browsers memory anyway... im just trying not to store it twice as it's just bad code!! any ideas if i need to write another line or not? (which would be)... response.cookies.add(New HttpCookie("cookieName", "cookieValue") ' session cookie in client browser memory thanks guys

• Is there a way to put relationships/contraints into CSS?

  - by hekevintran

  In every design tool or art principle I've heard of, relationships are a central theme. By relationships I mean the thing you can do in Adobe Illustrator to specify that the height of one shape is equal to half the height of another. You cannot express this information in CSS. CSS hard-codes all values. Using a language like LESS that allows variables and arithmetic you can get closer to relationships but it's still a CSS variant. This inability in my mind is the biggest problem with CSS. CSS is supposed to be a language that describes the visual component of a Web page but it ignores relationships and contraints, ideas that are at the core of art. How possible is it to imagine a new Web design language that can express relationships and contraints that can be implemented in JavaScript using the current CSS properties?

• Redmon's Run As User not loading user's enviroment variables

  - by catfish

  I'm attempting to use Redmon http://www.winimage.com/misc/redmon/ to send print jobs to a custom C# application. Redmon "runs" (actually the Print Spooler) as SYSTEM but has an option to Run As User to allow your application to run under the user that printed the job. The problem is that it doesn't appear to load the user's environment. So calling functions like Path.GetTempPath() points to \windows\temp instead of the user's. Also when attempting to run Outlook 2007+ via MAPI calls (to add attachments) it reports form errors due to, I think, the temp folder location. Is there a way to "reload" a profile or atleast get your environment vars within the Impersonated application? The only ideas I've had so far is to rebuild the vars directly from the registry, but I want to avoid this since it's a hack around (avoiding implementation details and all that). Or making a stub program that Redmon calls which then properly Run As User with full profile the custom application. Any other items or tricks?

• How to add global exception handling to a add-in dll?

  - by redjackwong

  Here's my context: I am writing a WPF add-in for an application. This Application's main thread is unmanaged. I want to add a global exception handling system for this add-in to handle any unhandled exceptions. Here's what I've tried but not working: I cannot add a try-catch block to my Application.Run() code line. Because I am an add-in, that code fragment is in the application. System.Windows.Forms.Application.ThreadException is not working too. There might not be an WinForm Application exists. (WPF hosting in unmanaged code.) AppDomain.CurrentDomain.UnhandledException is not working too. Because maybe it's handled by the Application itself. It just doesn't enter my code. So, any ideas for this situation?

• Are these AVAudioSettings right?

  - by Dyldo42

  self.recordSettings = [NSMutableDictionary dictionary]; [recordSettings setValue:[NSNumber numberWithInt:kAudioFormatAppleIMA4] forKey:AVFormatIDKey]; [recordSettings setValue:[NSNumber numberWithFloat:44100.0] forKey:AVSampleRateKey]; [recordSettings setValue:[NSNumber numberWithInt:1] forKey:AVNumberOfChannelsKey]; recordSettings is declared in my view's header file and initialised in its viewDidLoad method. For some reason, everything is working in the simulator, but on a device, the [recorder record] method is returning NO. The only theory I have is that something in the recordSettings isn't compatible with an actual device. Any ideas?

• iPad/iPod: autoRotate resizes view in window

  - by Jasconius

  Developing an iPad interface, I have a scenario where I have a UIViewController which manages a view that gets placed directly as a subview of the main UIWindow. Before being placed in the UIWindow, that view gets resized to a non-standard size, let's say, 768x460, and positioned at the bottom of the screen. When rotating the device, the autoRotate feature of the UIViewController causes the view to be resized so that it fills the entire UIWindow space. I thought this might be because in the XIB, the view is set to window size, but when I changed it to reflect the desired size, it still expanded it to the window size. Then I went into the MainWindow XIB and turned off autoresizeSubviews, and it still happens. This is a very frustrating problem, I am hoping that there is merely something obvious that I am missing out on. Anyone have any bright ideas?

• ASP.NET - dynamically creating database connection in datasets

  - by Foo

  I am currently using datasets for my data access layer. I currently store the connection string in the web.config file. I need the ability to change the connection to another database before any queries are processed. Is there an event that is triggered or a base class that can be modified that intercepts the process of retrieving the connection string from the web.config file? Is there any way to handle multiple database connections using the same code base and also take advantage of the connection pooling? I understand the best method is to get rid of datasets and use custom data objects. Any ideas?

• dojo parser not escaping quotation marks in attributes?

  - by peirix

  Whenever I'm using quotation marks inside an attribute value in dojo, it seems dojo's parser isn't handling it very well... <textarea name="content.locale['en']" dojoType="dijit.form.SimpleTextarea"> </textarea> Turns into: <textarea ]="" en="" name="content.locale["></textarea> With the surrounding <div>s and what not is added by the dijit widget. Any ideas? EDIT Seems this is working as it should with other elements, it's just the SimpleTextarea that's causing a problem..

• Generated Word 2007 prints scrunched up

  - by Brad

  Our website generates Word 2007 documents from database data by creating the xml, zipping it and sending it as a MIME attachment. Usually, this works fine. On occasion, the document will look fine on the screen, but not when printed. The letters end up scrunched together. Here is an example. This is a 1 page document, the first page is a scan of the document printed correctly, the 2nd page is a scan of the same document printed with the problem. Here is the original document. Has anyone ever seen anything similar? I cannot figure out if this is a bug in the code that generates our XML, a bug in the printer driver or a bug in Word. Any ideas would be greatly appreciated. Please note that this document does not contain any real data other than public information, but disregard the contents - this is not an official document, and only meant to illustrate our problem.

• Convert a user's search string into a MS SQL `Full-Text Query` Search Phrase

  - by Atomiton

  I've search for answers for this and I can't seem to find an answer to what should be somewhat simple. This is related to another question I asked, but it's different. What's the best way to take a user's search phrase and throw it into a CONTAINSTABLE(table, column, @phrase, topN ) phrase? Say, for example the user inputs: Books by "Dr. Seuss" What's the best way to turn that into something that will return results in my ContainsTAble() phrase? I was previously parsing the search phrase and writing something like ISABOUT("Books" WEIGHT(1.0), "by" WEIGHT(0.9), "Dr. Seuss" WEIGHT(0.8)) as my @phrase but ISABOUT seems to be returning odd results... especially when one word searches are entered. Any Ideas?

• Glassfish v3 Domain Output Log is not ending after the netbeans debug is stopped

  - by Nassign

  I would like to know if anybody is experiencing the problem on endless if log that is too long when Netbeans Debugging session is stopped? We use java logging in our web application but if I stop the debug, suddenly in the Output Glassfish v3 Domain window, there are a lot of log that is being dump. The log would last so long, that I need to click the Stop the Server because if I don't the Netbeans logger would consume too much memory that makes it too slugish later. I am not sure how long until the log stop but it last for minutes. Any ideas here?

• IE6 - body shrink on hover / z-index change

  - by Kasper

  I'm debugging a site to make it work for IE6 (god, please, let this be the last time). I've gotten pretty far with getting the the layout look right. There's just one more thing bugging me. Some elements like links, when they get hovered, the body of the site shrinks. I have built a dropdown with javascript. When it should show, the body of the site shrinks. There is a slideshow, made with javascript, which changes the z-index of the images, everytime it changes the z-index, the body shrinks. Now I found some information that IE6 creates this specific shrinking behaviour when using a fixed position element. But this is not the case. Someone here have some ideas for solving this? Thanks!

• Strange crashes on the iPad device with core graphics functions

  - by toastie

  I am getting a lot of strange EXC_BAD_ACCESS crashes on the iPad that only happen on the device and not in the simulator. I am assuming that they are somehow memory related, but I am not sure. They all happen with image context related functions. One strange example is using CGImageCreateWithImageInRect. For example, if i run through a bunch of UIImages and crop them with CGImageCreateWithImageInRect, it will always crash at specific arbitrary sizes. Like, if I crop them all to 200x200, it crashes out after processing 12 images. If i crop them to 210x210, it works no problem. The EXC_BAD_ACCESS happens inside of "memmove" called from "CGBlt_copyBytes". That is all the debugger shows me strangely enough. I can't see the callstack going up to any of my methods. All of this works fine in the simulator! I know this is all very vague, but if anyone has any ideas, they would be greatly appreciated.

• accessing embedded object with jquery not working in firefox 3.6

  - by taber

  Hi, this code in my plugin used to work just fine: jQuery('#embedded_obj', context).get(0).getVersion(); and in html... <object id="embedded_obj" type="application/x-versionchecker-1.0.0.1"</object Basically trying to get the properties from an embedded object. But it looks like get(0) is returning an html object instead of the actual embedded object. For example, if I do: var launcher = jQuery('#embedded_obj', context).get(0); for(prop in launcher){ alert(prop + ': ' + launcher[prop]); } ... it alerts things like "getElementByNode," "scrollWidth," "clientLeft," "clientTop" etc. Again this worked before Firefox 3.6. Has anyone else seen this or have any ideas/suggestions? Thanks!

• Regular Expressions: Positive Lookahead and Word Border question

  - by Inf.S

  Hello again Stackoverflow people! Assume I have these words: smartphones, smartphone I want to match the substring "phone" from within them. However, in both case, I want only "phone" to be returned, not "phones" in the first case. In addition to this, I want matches only if the word "phone" is a suffix only, such that: fonephonetics (just an example) is not matched. I assumed that the regex (phone([?=s])?)\b would give me what I need, but it is currently matching "phones" and "phone", but not the "fonephonetics" one. I don't need "phones". I want "phone" for both cases. Any ideas about what is wrong, and what I can do? Thank you in advance!

• Protecting Data Feed for iPhone App

  - by Chris

  I am creating an App that pulls data from a file on my server. That file gets data from my database, based on GET values that are passed through the URL. I would like to keep this feed closed - that is, I don't want people finding the datasource and reading the data on their own. I considered sending an alphanumeric id along with the url string, but if they can find the URL that I am calling, then there won't be anything preventing them from grabbing that alphanumeric id also. I am looking for any ideas or experiences that might help me here. Thanks.

• how to optimize illustrator artwork in flash?

  - by sasi

  I'm working on a flash project that incorporates a lot of artwork done in Illustrator CS4. I've been copy-pasting directly from Illustrator into Flash, and I add some animations as well. Final file is going to be a one single swf file which will be a part of UI for an application and .net will be the core for this. But now flash becomes unusable slow to respond for actions. My machine is a fast i7 with 6gb of RAM, so I don't think that's the issue. We are going to use this file with dual core atom processors. Does anyone have ideas for alternative importing techniques, optimizations within illustrator, anything at all that will make this more manageable? Thanks
