• JQuery UI Tabs + Wordpress issues

  - by Sahat

  Hello dear Stackoverflow gurus, I am trying to integrate JQuery tabs with my WordPress blog, to replace old HTML Navigation menu. I am half way there but not quiet... Take a look for yourself: http://www.isahat.com The template breaks right away since the first button of the Tab menu is linked to index.php like so: Home Info The second tab menu shows my Info page just fine, but on top of everything else. My home page and everything else gets shifted down to make room for Info page. And why after clicking on any article or even the tab link, my tab menu disappears and all my navigation links turn into a bullet list? Thank you, Sahat.

• Given two lines on a plane, how to find integer points closest to their intersection?

  - by Lukasz Lew

  I can't solve it: You are given 8 integers: A, B, C representing a line on a plane with equation A*x + B*y = C a, b, c representing another line x, y representing a point on a plane The two lines are not parallel therefore divide plane into 4 pieces. Point (x, y) lies inside of one these pieces. Problem: Write a fast algorithm that will find a point with integer coordinates in the same piece as (x,y) that is closest to the cross point of the two given lines. Note: This is not a homework, this is old Euler-type task that I have absolutely no idea how to approach. Update: You can assume that the 8 numbers on input are 32-bit signed integers. But you cannot assume that the solution will be 32 bit.

• why arrayfun does NOT improve my struct array operation performance

  - by HaveF

  here is the input data: % @param Landmarks: % Landmarks should be 1*m struct. % m is the number of training set. % Landmark(i).data is a n*2 matrix old function: function Landmarks=CenterOfGravity(Landmarks) % align center of gravity for i=1 : length(Landmarks) Landmarks(i).data=Landmarks(i).data - ones(size(Landmarks(i).data,1),1)... *mean(Landmarks(i).data); end end new function which use arrayfun: function [Landmarks] = center_to_gravity(Landmarks) Landmarks = arrayfun(@(struct_data)... struct('data', struct_data.data - repmat(mean(struct_data.data), [size(struct_data.data, 1), 1]))... ,Landmarks); end %function center_to_gravity when using profiler, I find the usage of time is NOT what I expected: Function Total Time Self Time* CenterOfGravity 0.011s 0.004 s center_to_gravity 0.029s 0.001 s Can someone tell me why? BTW...I can't add "arrayfun" as a new tag for my reputation.

• ucommerce: how to change category template

  - by autonomatt

  Using uCommerce 2, umbraco 4.7. I have a category side nav showing the categories using: <a> <xsl:attribute name="href"> <xsl:value-of select="CommerceLibrary:GetNiceUrlForCategory($catalogueName, @id)"/> </xsl:attribute> <xsl:value-of select="@displayName"/> </a> First of all, when hovering over the links it still shows an old catalogue name, even though I've renamed the catalogue and also hardcoded the catalogue name into: <xsl:variable name="catalogueName" select="'MyCatalogue'"/> When I click on the link generated by GetNiceUrlForCategory I get the standard template that comes with uCommerce started site. I've tried deleting the whole started site, but I just can't get it to link to a template I did for the category. I still don't quite understand how ucommerce knows which template to use for a category link. Soren? :) Cheers, Matt

• .NET - Verify and Install .NET Framework 3.5 before running application

  - by Tufo

  PLEASE READ THE FULL QUESTION BEFORE POST YOUR ANSWER Hello guys! I'm currently developing a "Extremelly customized Installer Application" in C# for installing a old classic ASP application. It'll be used during the 2.0 version is developed (ASP.NET MVC with C#). As its so different from the efault install packages, I've made it as normal windows application, not as setup application (a setup application don't let us customize so much as I need). And here is the problem: As its a windows application, I must "Release" it and send the compiled .EXE with the .DLLs, I must not "Publish" because if i do so, the published .EXE will "install the installer" and not my application. I need a way to verify and install the .NET Framework 3.5 like a bootstrap package prerequisite used in publishing option, but remember that I'm not publishing, I'm doing a "Release" build. Thanks for any help!

• Microsoft SQL Server 2005/2008 SSIS are oversized

  - by Ice

  In this case i'm old style and loved 'my fathers DTS' from SQL 2000. Most of the cases i have to import a flatfile into a table. In a second step i use some procedures (with the new MERGE-Statement) to process the imported content. For Export, i define a export-table and populate it with a store proc (containing a MERGE-Statement) and in a second step the content will be exported to a flat file. In some cases there is no flat file because there is annother sql-server or in rare cases an ODBC-Connection to a sybase or similar. What do you think? When it comes to complex ETL-Stuff the SSIS may be the right tool...but i haven't seen such a case yet.

• Windows azure deployment

  - by smoothe

  I just built a simple hello world windows azure service containing just one web role, I used visual studio 2008 and Windows azure tools for VS 1.2 I am pretty new to this and I have been trying to deploy an application all afternoon now. I'm in australia and deploying in the region Asia anywhere. I have pretty much followed the info provided on MSDN and it says uploaded 95% then after about ten minutes the deployment disappears. I have tried using the old windows azure developer portal and 30minutes later I can not access the service and it's status is either busy or stopped. I have the introductory offer for an extra small compute instance on the subscription I am deploying to. Can anyone with experience with windows azure elaborate on the subject of deploying apps and the status on my application, I am very keen to get into the platform and this issue has just about spoiled my weekend.

• Redirecting a large number of URLs with htaccess or php header

  - by Peter

  I have undergone a major website overhaul and now have 5,000+ incoming links from search engines and external sites, bookmark services etc that lead to dead pages or 404 errors. A lot of the pages have corresponding "permalinks" or known replacement hierarchy/URL structure. I've started to list the main redirects with htaccess or physical files with simply a header location reidrect which is clearly not sustainable! What would be the best method to list all of the old link addresses and their corresponding new addresses with htaccess, php headers, mysql, sitemap file or is it better to have all broken links and wait for search engines etc to re-index my site? Are there any implications for having a large number of redirecting files for this temporary period until links are reset?

• C/C++ usage of special CPU fetures

  - by b-gen-jack-o-neill

  Hi, I am curious, do new compilers use some extra features built into new CPUs such as MMX SSE,3DNow! and so? I mean, in original 8086 there was even no FPU, so compiler that old cannot even use it, but new compilers can, since FPU is part of every new CPU. So, does new compilers use new features of CPU? Or, it should be more right to ask, does new C/C++ standart library functions use new features? Thanks for answer.

• Access DB with SQL Server Back End

  - by uyuni99

  I have an old Access application that has a lot of code in forms and reports. The database is getting too large and I am thinking of moving the back end to SQL Server. My requirements are as follows: The DB needs to be multiuser and the users (3-5) will need to log in over the web I would prefer not to re-write the forms and reports in ASP or some other web front end. When I think about my choices, I see them as: Have an Access ADP front end and allows remote log-in to the server where it is stored. Not sure if it is possible for 2 users to simultaneously log in Distribute an ADP front end to the users, but I am not sure if it is possible to connect to a SQL Server back end over the internet, and the network traffic may be an issue. Any other solution? I appreciate all help. u

• How to step frames in a movie recorded by iPhone

  - by aron

  Is there a way to have my iPhone program step frame by frame through a movie recorded by the iPhone? What I want to do is have the user record a quicktime movie, then be able to step through the movie frame by frame. Alternately, I suppose if there was a way to extract every single frame from the movie to a jpg, then I could easily step through the pictures. Anyone know of a way to do this??? I suppose the third option (which might not get past Apple's store) is to capture the movie the way the old jailbroken apps did, which is somehow capture the pictures directly from the camera view???? Any help appreciated. Thanks in advance!!!!

• How do I disable maven build when using Maven 2.0 integration for eclipse?

  - by Stein G. Strindhaug

  How do I stop the "Maven 2.0 integration" plugin from running maven build, while keeping "build automatically" checked? I'm pretty sure it used to be some check box to disable maven build before, but after upgrading Ubuntu; eclipse seems to have been updated in the process, and now I cannot find any way to turn off the maven build. The maven build takes literally minutes (about 5 minutes or so), while just running java build used to finish in seconds. Is it no longer possible to disable it or have they just hidden it well? If it's not possible, will eclipse be able to compile my maven project without the plugin? (Trying to google for a solution the closes I got to an answer was several archives of this old post where the answer essentially were "You should be able to disable Maven builder in project preferences..." which doesn't really help because I cannot find any on/off settings there)

• WM6x IMAPIAdviseSink::OnNotify threading issues

  - by violet313

  specifically WM6x, winCE5x Now my current understanding from trawling the msdn etal is that the IMAPIAdviseSink::OnNotify callback can be made from any old thread; from (ce)mapi or perhaps even from a third-party service provider. Under WM6x, i cannot seem to coax an in-thread response by invoking HrThisThreadAdviseSink, since while this function is declared in mapiutil.h, a definition appears not to exist (in cemapi.lib or wherever??) ~But i notice that all the OnNotify callbacks i receive derive from windows messages that i am receiving on my thread (=looks to me like an in-thread implementation in any case under cemapi)... So, can anyone confirm that this is infact always the case -or am i just getting lucky right now? ah, i should add that my advise source is IMAPISession::Advise erm i should also say that i might have cross-posted this on the msdn forum -but they're mostly numptys over there,,

• Best way to implement nested loops in a view in asp.net mvc 2

  - by Junior Ewing

  Hi, Trying to implement some nested loops that are spitting out good old nested html table data. So the question is; What is the best way to loop through lists and nested lists in order to produce easily maintainable code. It can get quite narly quite fast when working with multiple nested tables or lists. Should I make use of a HTML helper, or make something with the ViewModel to simplify this? A requirement is if there are no children at a node there should be an empty row on that spot with some links for creation and into other parts of the system.

• Full GC real time is much more that user+sys times

  - by Stas

  Hi. We have a Web Java based application running on JBoss with allowed maximum heap size of about 1.2 GB (total machine physical memory is 2 GB). At some point the application stops responding (to clients) for several minutes. After some analysis we found out that the culprit is the Full GC. Here's an excerpt from the verbose GC log: 74477.402: [Full GC [PSYoungGen: 3648K-0K(332160K)] [PSOldGen: 778476K-589497K(819200K)] 782124K-589497K(1151360K) [PSPermGen: 102671K-102671K(171328K)], 646.1546860 secs] [Times: user=3.84 sys=3.72, real=646.17 secs] What I don't understand is how is it possible that the real time spent on Full GC is about 11 minutes (646 seconds), while user+sys times are just 7.5 seconds. 7.5 seconds sound to me much more logical time to spend for cleaning <200 MB from the old generation. Where does all the other time go? Thanks a lot.

• How do I send an email from my webpage?

  - by Jordan S

  I am not a web developer but I do have a lot of programming experience in C# and Windows forms programming. On our company webpage my boss wants me to put in a textbox where visitors can submit a comment and press a submit button and that comment will be sent to an email address. Right now, our website uses just plain old html, no php or javascript or anything like that. I am wondering what is the simplest way to accomplish what I need? Can someone point me in the right direction? The website is hosted on an Apache server so I won't be able to use aspx.

• PHP Fatal error on line number that doesn't exist

  - by alexantd

  Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 523800 bytes) in /Library/WebServer/Documents/XMLDataStore.class.php on line 981 The curious thing about this error is not the memory leak, which would be easy enough to troubleshoot. Rather, it is the fact that XMLDataStore.class.php is only 850 lines long, which I have verified in multiple text editors. This is with the PHP 5.3 bundled with Snow Leopard. I'm not using an opcode cache. Here is my php.ini: allow_url_fopen = Off error_reporting = -1 display_errors = 1 display_startup_errors = 1 date.timezone = 'America/Los_Angeles' output_buffering = Off realpath_cache_size = 0k XMLDataStore.class.php has recently been refactored and it used to be longer than 981 lines. It's almost as if PHP has cached a 2-week-old version and is reading that. I'm positive that the current version at /Library/WebServer/Documents/XMLDataStore.class.php is only 850 lines long, though.

• Parsing plain data with Javascript (JQuery)

  - by Angelus

  Well , I have this text in a Javascript Var: GIMP Palette Name: Named Colors Columns: 16 # 255 250 250 snow (255 250 250) 248 248 255 ghost white (248 248 255) 245 245 245 white smoke (245 245 245) 220 220 220 gainsboro (220 220 220) 255 250 240 floral white (255 250 240) 253 245 230 old lace (253 245 230) 250 240 230 linen (250 240 230) 250 235 215 antique white (250 235 215) 255 239 213 papaya whip (255 239 213) And What I need is to cut it in lines and put them in one Array , after that i must separate each number and the rest in an string. I'm getting crazy searching functions to do that but now i can't see anyone in Javascript. modified End expected format will be first the next: array[0]='255 250 250 snow (255 250 250)' Then i wanna take it and extract each line into some vars to use them: colour[0]=255; colour[1]=250; colour[2]=250; string=snow (255 250 250); (the vars will be reused with each line)

• vb.net : is it possible to connect to sql server 2008 via odbc but not through vb.net code?

  - by phill

  I'm supporting an old vb.net program whose database it connected to was moved from SQL Server 2005 to SQL Server 2008. Is there a setting on SQL Server 2008 which will allow ODBC connections to access the database but not allow VB.NET to connect to it programmatically? the error i keep receiving in the app is: An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: Named Pipes Provider, error: 40 – Could not open a connection to SQL Server) however I can connect to it when I create a system dsn to the sql server instance and through VS2005's Tools Connect to Database. Here is the code I'm using to connect: dim strC as string strC = "data source=bob; database=subscribers; user id=bobuser; password=passme" dim connection as New SqlClient.SqlConnection(strC) try connection.open() catch ex as Exception msgbox(ex.message) end try connection.Close()

• When is it useful to define your own delegates instead of using the generics?

  - by Carlos

  I've been going through some old code, where I came across some custom defined delegates, which are used thus: private delegate void ListenDelegate(UdpClient listener, bool multicast); private void ListenOn(UdpClient listener, bool multicast) { new ListenDelegate(_ListenLoop).BeginInvoke(listener, multicast, null, null); } With some of the new .NET framework versions, you can do the following: private void ListenOn(UdpClient listener, bool multicast) { new Action<UdpClient, bool>(_ListenLoop).BeginInvoke(listener, multicast, null, null); } This ought to be exactly the same. Is there any point in defining your own delegates, when the generic delegates seem to do the same job with less space? Or have I missed something about the generics that makes them not equivalent?

• Which file is the COM++ object and how do I import it to .NET?

  - by Bad Man

  I'm trying to write a COM++ object wrapper around a Qt widget (control) I wrote so I can use it in future .NET projects. e.g.: public __gc class comWidget; In the compile directory are the .exe, an exe.intermediate.manifest, and the comWidget.obj, and also some other crap files (.pdb, etc). So what/how do I import into .NET? I feel like I'm missing an important step for registering the object or whatever, but all these tutorials are terrible outdated and ridiculously unhelpful (for instance, I'm using the old CLR syntax because I can't find any good docs on the new stuff, thx again M$ for being lazy faggots as usual)

• jQuery: event that tracks click in browser autocomplete

  - by Fernando

  I have a keyup event on an input. This event works fine for auto complete when you select a value and press enter. But it doesn't work when you click at an auto complete value. Is there an event that i can use in such case? I already tried the change one but it doesn't work. Thanks! Edit: Maybe i was not clear but i am referring to the autocomplete feature that browsers have. I am not trying to build my own. Example: I have the following event: $('.product').keyup(searchByProduct); When user clicks at this input the old values that he already typed shows up ( it's the browser that does this ). If he clicks on one of the values, the function searchByProduct is not called. Which event do i have to register to track this click ( and that the input content has changed )?

• Custom constructors for models in Google App Engine (python)

  - by Nikhil Chelliah

  I'm getting back to programming for Google App Engine and I've found, in old, unused code, instances in which I wrote constructors for models. It seems like a good idea, but there's no mention of it online and I can't test to see if it works. Here's a contrived example, with no error-checking, etc.: class Dog(db.Model): name = db.StringProperty(required=True) breeds = db.StringListProperty() age = db.IntegerProperty(default=0) def __init__(self, name, breed_list, **kwargs): db.Model.__init__(**kwargs) self.name = name self.breeds = breed_list.split() rufus = Dog('Rufus', 'spaniel terrier labrador') rufus.put() The **kwargs are passed on to the Model constructor in case the model is constructed with a specified parent or key_name, or in case other properties (like age) are specified. This constructor differs from the default in that it requires that a name and breed_list be specified (although it can't ensure that they're strings), and it parses breed_list in a way that the default constructor could not. Is this a legitimate form of instantiation, or should I just use functions or static/class methods? And if it works, why aren't custom constructors used more often?

• How do you resolve the common naming collision between type and object?

  - by Catskul

  Since the standard c# convention is to capitalize the first letter of public properties, the old c++ convention of initial capital for type names, and initial lowercase for non-type names does not prevent the classic name collision where the most obvious object name matches the type name: class FooManager { public BarManager BarManager { get; set; } // Feels very wrong. // Recommended naming convention? public int DoIt() { // 1st and 2nd Bar Manager are different symbols return BarManager.Blarb + BarManager.StaticBlarb; } } class BarManager { public int Blarb { get; set; } public static int StaticBlarb { get; set; } } It seems to compile, but feels so wrong. Is there a recommend naming convention to avoid this?

• How can I receive messages using over http without MSMQ

  - by pduncan

  I need a reliable messaging framework that runs over http/https (due to client security requirements) and that doesn't use MSMQ (because some clients will use Windows XP Home). The clients only need to be able to receive messages, not send them. We already have a message queue on the server for each user, and the receivers have been getting messages by connecting to an HttpHandler on the server and getting a Stream from WebResponse.GetResponseStream() We keep this stream open, and pull messages off of it using Stream.Read(). This MOSTLY works, but Stream.Read() is a blocking call, and we can't reliably interrupt it. We need to be able to stop and start the receiver without losing messages, but the old stream often hangs around, even after we call Thread.Abort on its thread. Any suggestions?
