  • Using jQuery's animate(), if the clicked on element is "<a href="#" ...> </a>", the fucntion should

    - by Jian Lin
    I was reading jQuery's page for animate() http://api.jquery.com/animate/ Its examples don't mention about if using <a href="#" id="clickme">click me</a> ... $('#clickme').click(function() { $('#someDiv').animate({left: "+=60"}); }) we actually still have to return false like in the old days? $('#clickme').click(function() { $('#someDiv').animate({left: "+=60"}); return false; }) (but then, those examples didn't use a <a> for the "click me"... but used something else. Otherwise the page will jump back to the beginning of the page? Does jQuery have a more elegant or magical way of doing it?

  • MacBook for django development?

    - by Fernando
    Hi, I'm about to buy a new laptop (Asus G62) to replace my old ubuntu desktop. I will use it mostly for django development (and some legacy win32 stuff in a virtualbox). However, since I will need to do some iPhone development in the near future, I'm starting to think that it might be a wiser to buy a MacBook Pro, instead of the Asus and later a cheap (so to speak...) MacBook. How well suited is a MacBook Pro for Django development? I currently use WingIDE on Linux and love it, how does the Mac version compare to the linux one? Is the Ubuntu - Mac OS transition complicated? Will I be able to leverage my Linux knowledge? OTOH, I'm your average nerd, so I'm not sure if I'm cool enough for a Mac. Besides, having a double chin, a black turtle neck is completely out of question. Thanks in advance!

  • Opening MS Excel worksheet in C#

    - by topgun_ivard
    I know we can open a particular worksheet of MS Excel using C# by providing the sheet number (1,2,3..) or name (sheet1, sheet2, sheet3...) I have a excel file which has 2 sheets, 1. Values, 2. Results Is there a way to open a sheet giving the sheet name ,i.e, "Values" instead of 1 or [s|S]heet1 in C# ?? I looked thru the old posts but didnt find anything useful... so again, what I am trying to do is, open a Excel worksheet by using its user defined name (Values) instead of the system defined name(1 or [s|S]heet1) any inputs would be greatly appreciated!

  • Moving Webdav app from Win server 2k to Win server 2k3 now getting authentication issues.

    - by John
    I have an intranet web app that uses CSS httpFolder to map a webdav folder to an IFrame on a web page. The user then can drop files in the frame and the page processes them when the user presses the button. This works well on a Win 2k SP4 server running IIS 5. I have moved the app over to a Win 2k3 server running IIS 6. I have made sure the WebDAV extensions are allowed. I have set everything else in IIS to match the original installation on the old server. But when I try to access the WebDAV folder I am repeatedly prompted for my login credentials. I use my domain admin login but even that doesn't work. What am I missing? What differences are there between WebDAV on 2k vs 2k3? TIA John

  • Caching the repository index in m2eclipse

    - by Titi Wangsa bin Damhore
    everytime i start with a fresh new workspace, m2eclipse downloads nexus-maven-repository-index.gz from the maven central repository. this is good. but, some times, i just want to start a new workspace, and not wait for it to download, it tried copying the whole .metadata directory from an old workspace to the new one, but the list of maven artifacts are still empty. is there a way i can cache it? or at least download the file once, and the copy/extract/repackage it so that m2eclipse thinks it has already downloaded it and allows me to search for maven artifacts. or a short version of the question where and in what format is the "nexus-maven-repository-index.gz" file stored in the workspace?

  • Prevent my program from being flagged as malware

    - by user120242
    I know that this kind of behavior should be avoided in a publicly deployed program, but it's necessary. I do some hooking of process creation and file/registry I/O, and unpacking. I still trip a heuristic here and there, and I'm worried about future detections. Could I just contact as many AV vendors as I can, submit my program, and provide a link to my program being served publicly? Would it be possible to convince AV vendors to "whitelist" it? Does anyone perhaps have a list of places to submit false positives? Another problem I have is with people who don't update their malware scanners. There seems to be many people who just have old malware defintions and never bother to update. Is there anything that can be done about this? Or, if not, a way to check older definitions so I can locate what is being tripped, so I can try to avoid using that code?

  • I am not able launch JNLP aaplications using "Java Web Start"?

    - by akjain
    Up until recently, I was able to launch/open JNLP files in Firefox using Java web start. Don't know what happened all of a sudden JNLP files stopped launching, a splash screen appears saying Java Starting... and then nothing happens. Even the Java Console in the browser and javacpl.cpl applet doesn't open. Tried all possibilities: removed all older version and installed the latest JRE (java version "1.6.0_17"), still it doesn't work. Done some googling for this problem, people suggested to start javaws.exe with -viewer option but same behavior (a splash screen appears saying "Java Starting..." and then disappears) The problem is that I don't know any place (logs etc.) to look for to see what is causing the problem. I am using WinXP SP3, and some of the screenshots below shows further info about my system. I can provide any other detail if required but please help me solve this problem. Update: Although this question is bit old, Following solution fixed above issue for me (indeed this was the actual cause)

  • How can i create a submitable form that contains dynamically added and removed controls

    - by bill
    Hi All, I am trying to create a form that is made up of controls with values that represent an entity with multiple child entities. The form will represent a product with multiple properties where the user will then be able to create options with multiple properties which in turn be able to create multiple option-items with multiple properties. My question is what is the best approach? Can i use ajax to avoid postbacks and having to rewrite the controls to the page? If i dynamically add the controls in the form of table rows or grid rows will the data/control values be available in the code-behind when i submit? This is an age old question.. the last time i had to do this was .Net 2.0, pre-ajax (for me) and i was forced to recreate all the controls on each post back. thanks!

  • Problems using MySQL instead of MySQLi

    - by vaibhav
    I have a blog, which is on Drupal v6.14. Recently I changed my web hosting provider. My new hosting provider does'nt support MySQLi. So I have to use MySQL instead of MySQLi. All things worked fine for some days. But on a very fine morning, I found my blog is down and the error message was Mysql: Too Many Connections to the server. And this problem occurs several times a day now. I contacted my web hosting provider, they said, its a problem in your database. I don't trust this. My blog was working fine at old web server. Can it be a problem because of I moved to MySQL from MYSQLi.

  • How to obtain specific Excel object library without the corresponding Office version installed.

    - by james-h-l
    I am developing a Excel automation app that read and write to Excel spreadsheet. I have Office 2007 installed on my machine. I therefore can reference the Excel 12.0 Object Library and the Excel 5.0 Object Library. I don't want to use Excel 5.0 because it's really quite old and poorly documented. Therefore I'm referencing Excel 12.0. However the target machine have Office 2003 installed and therefore only have Excel 11.0. So when I compile my program it crashes on the target machine since the referenced library are different. I was wondering is there a way I could obtain the Excel 11.0 without installing Office 03? I tried to find answers from msdn and microsoft support page but couldn't find anything? This is quite strange since it could also happen in the future where developers has newer editions of Office than clients?

  • Parallel port no longer accessible even though no changes to system.

    - by marcusw
    I have an old Dell Dimension 8200 running Gentoo which I use solely to control various things using the parallel port. After shutting it down a few weeks ago, I started it up again today and tried to access the parallel port like I usually do. Unfortunately, my code bombed out when it tried to call ioperm(888,1,1) to grab the parallel port which returned an error code of -1. There have been no changes to the system be it hardware or software, no updates, no tweaking, no dropping the case, no over-amping the data pins, nothing. The port and the software have been working fine for months with no changes, and were working fine when I shut it down last. Running my code with root privileges changes nothing. What is breaking this and how can I fix it?

  • Rails 3: Validate combined values

    - by Cimm
    In Rails 2.x you can use validations to make sure you have a unique combined value like this: validates_uniqueness_of :husband, :scope => :wife In the corresponding migration it could look like this: add_index :family, [:husband, :wife], :unique => true This would make sure the husband/wife combination is unique in the database. Now, in Rails 3 the validation syntax changed and the scope attribute seems to be gone. It now looks like: validates :husband, :presence => true Any idea how I can achieve the combined validation in Rails 3? The Rails 2.x validations still work in Rails 3 so I can still use the first example but it looks so "old", are there better ways?

  • update columns when value is numeric in tsql

    - by knittl
    i want to normalize date fields from an old badly designed db dump. i now need to update every row, where the datefield only contains the year. update table set date = '01.01.' + date where date like '____' and isnumeric(date) = 1 and date >= 1950 but this will not work, because sql does not do short circuit evaluation of boolean expressions. thus i get an error "error converting nvarchar '01.07.1989' to int" is there a way to work around this? the column also contains strings with a length of 4, which are not numbers (????, 5/96, 70/8, etc.) the table only has 60000 rows

  • LINQ to SQL or Entities, at this point?

    - by orlon
    I'm a bit late to the game and have decided to spend some spare time learning LINQ. As an exercise, I'm going to rewrite a WebForms app in MVC 2 (which is also new to me). I managed to find a few topics regarding LINQ here (http://stackoverflow.com/questions/16322/learning-about-linq, http://stackoverflow.com/questions/8050/beginners-guide-to-linq, http://stackoverflow.com/questions/252683/is-linq-to-sql-doa), which brought the concern of Entities vs SQL to my attention. The threads are all over a year old however, and I can't seem to find any definitive information on which ORM is preferable. Is Entities more or less LINQ to SQL 2.0 at this point? Is it still more difficult to use? Is there any reason to use LINQ to SQL, or should I just jump into Entities? The applications I write at my present employer have a lengthy lifecycle (~10 years), so I'm trying to pick the best technology available.

  • What format do I use to store a relatively small amount of user data

    - by wcm
    I am writing a small program for our local high school (pro bono). The program has an interface allows the user to enter school holidays. This is a simple stand alone Windows app. What format should I use to store the data? A big relational data is obviously overkill. My initial plan was to store the data in an XML file. Co-workers have been suggesting that I use JSON files, Access Databases, SQL Lite, and SQL Server Express. There was even a suggestion of old school INI files.

  • How should the Version field be used in Trac?

    - by Eric
    I use Trac to track bugs, and future changes in my software projects. Tickets in Trac have a "Version" field and I'm trying to figure out the best way to use this field. Say I find a series of bugs in version 1.0 of my software. I create tickets in track for each and assign them to version 1.0. Now say I fix some of the bugs, and add some of the new features and release version 1.1. But some of the old 1.0 bugs are still in 1.1. Should I change their corresponding tickets to version 1.1 because they also now exist in 1.1? Or should I leave them set to version 1.0 as a way of tracking what version the bug was found in, and just assume that any open tickets in older versions still exist in newer versions?

  • Check wether Excel file is Password protected

    - by Torben Klein
    I am trying to open an Excel (xlsm) file via VBA. It may or may not be protected with a (known) password. I am using this code: On Error Resume Next Workbooks.Open filename, Password:=user_entered_pw opened = (Err.Number=0) On Error Goto 0 Now, this works fine if the workbook has a password. But if it is unprotected, it can NOT be opened. Apparently this is a bug in XL2007 if there is also workbook structure protection active. (http://vbaadventures.blogspot.com/2009/01/possible-error-in-excel-2007.html). On old XL2003, supplying a password would open both unprotected and password protected file. I tried: Workbooks.Open filename, Password:=user_entered_pw If (Err.Number <> 0) Then workbooks.open filename This works for unprotected and protected file. However if the user enters a wrong password it runs into the second line and pops up the "enter password" prompt, which I do not want. How to get around this?

  • 3D Math: Calculate Bank (Roll) angle from Look and Up orthogonal vectors

    - by 742
    I hope this is the proper location to ask this question which is the same as this one, but expressed as pure math instead of graphically (at least I hope I translated the problem to math correctly). Considering: two vectors that are orthogonal: Up (ux, uy, uz) and Look (lx, ly, lz) a plane P which is perpendicular to Look (hence including Up) Y1 which is the projection of Y (vertical axis) along Look onto P Question: what is the value of the angle between Y1 and Up? As mathematicians will agree, this is a very basic question, but I've been scratching my head for at least two weeks without being able to visualize how to project Y onto P... maybe now too old for finding solutions to school exercises. I'm looking for the trigonometric solution, not a solution using a matrix. Thanks.

  • XDocument change all attribute names

    - by Dested
    I have an XDocument that looks similar to <root> <a> <b foo="1" bar="2" /> <b foo="3" bar="4" /> <b foo="5" bar="6" /> <b foo="7" bar="8" /> <b foo="9" bar="10" /> </a> </root> I wish to change the attribute foo to something else, and the attribute bar to something else. How can I easily do this? My current version (below) stack overflows with large documents, and has an awful smell to it. string dd=LoadedXDocument.ToString(); foreach (var s in AttributeReplacements) dd = dd.Replace(s.Old+"=", s.New+"=");

  • Rotation of ViewController in TabbarController

    - by hanno
    I have a custom UIViewController in a UITabbarController and want to respond to rotation events. When a rotation occurs, the tabbarcontroller and the viewcontroller get rotated. However, the view in the viewcontroller doesn't get redrawn properly: the layout doesn't autoresize and it is black on parts of the screen. The strange thing is that it works when I go to another tab and the back again to my original viewcontroller. What could possibly be wrong? I checked that didRotateFromInterfaceOrientation:fromInterfaceOrientation is being called. However, the view.frame.size values are still the old ones from before the rotation. That's probably not correct.

  • is there a tool to see the difference between two database tables in SQL Server?

    - by reinier
    What is a good tool to see the differences between 2 tables (or even better, the datasets returned by 2 queries). EDIT: I'm not interested in the schema changes. Just assume that the schemas are the same. background as to why: I'm porting some legacy code which can fill a database with some pre-calced data. The easiest way to see if I got everything right, is to check the output of the old program, with the new one. I was thinking that if there is some kind of 'diff' tool for databases, this might be great.

  • Did anyone see the spasticNav.js Menu for jQuery ?

    - by Ricky
    Helooo all, If anyone doesn't know what i'm talking about, this is the link: http://net.tutsplus.com/tutorials/html-css-techniques/how-to-build-a-lava-lamp-style-navigation-menu/ How can i click the menu, and make it “stick” :) without reloading the whole page ? The plugin takes a static state of the tag UL – and run the plugin on it. which mean that if i move the “currentPageItem” from the first LI tag and give it to the next LI tag – the spasticNav doesn’t run for each object again. it still “remembers” the old state. ( because the .js file run only once at the top of the page ) So what should I add to the code in order to get dynamic “Click” event ? ( without reloading the whole page [ ajax ] ) Does anyone have any ideas about this specific plugin ? Thanks.

  • Can I expect a performance gain from removing this JOIN?

    - by makeee
    I have a "items" table with 1 million rows and a "users" table with 20,000 rows. When I select from the "items" table I do a join on the "users" table (items.user_id = user.id), so that I can grab the "username" from the users table. I'm considering adding a username column to the items table and removing the join. Can I expect a decent performance increase from this? It's already quite fast, but it would be nice to decrease my load (which is pretty high). The downside is that if the user changes their username, items will still reflect their old username, but this is okay with me if I can expect a decent performance increase. I'm asking stackoverflow because benchmarks aren't telling me too much. Both queries finish very quickly. Regardless, I'm wondering if removing the join would lighten load on the database to any significant degree.

  • How to break a series of git commits into patches for submission to another project

    - by krosenvold
    So I've been bashing away at my favorite open source project for quite some time, and It's time for submitting issues with patches back. I have to regroup my commits more or less fully, and hopefully extract some pieces of code that can function as distinct patches to avoid code bombing. Currently I usually do something like this: rebase/squash everything to one commit since the old ones often don't make sense as patches undo that commit start adding stuff that I think fits to one commit, using add/add -i commit stash the rest test that commit re-apply the stash and start from 3 until all is accounted for It works, but is there a better way ?
