• Rotating Viewbox contents smoothly

  - by user204562

  I'm looking to teach myself better methods of doing things in WPF that I would normally do manually. In this case, I have a ViewBox with an image in it. I also have a button that uses a DoubleAnimation to rotate the image 90 to the right. This animation works fine, but obviously because it's square as it turns, the image does a "best fit" to the ViewBox which makes the rotation look quite bad, as it gets larger and smaller as its longest edge shrinks or grows to fit to that particular rotation angle. I am looking for any advice on the best way to handle this using appropriate WPF methods. Obviously I could do all the calculations manually, but I would be more interested in finding a way to use the controls and methods built into the .NET architecture. Thanks for your help.

• regex no character

  - by iamnotmad

  In this text: warning here there are several types of warnings in this string warning.gif at the end warning end of line warning I want to match every warning except warning.gif. I cannot seem to get it to include the last one that has no character (control or otherwise) after it. using warnings?[^\.] gets what I want except for the last warning (on the last line). I think because there is no character at all after. How can I get it to include that one?

• Is there a way to keep track of javascript hits?

  - by user54197

  I am populating a table based on a javascript function. I want to limit the data entered to 2, afterwhich I hide the table. Is there a way to track how many hits the javascript code gets hit? function addNewRow() { $('#displayInjuryTable tr:last').after('<tr><td style="font-size:smaller;" class="name"></td><td style="font-size:smaller;" class="address"></td></tr>'); var $tr = $('#displayInjuryTable tr:last'); var propertyCondition = $('#txtInjuryAddress').val(); $tr.find('.name').text($('#txtInjuryName').val()); if (propertyCondition != "") { $tr.find('.address').text($('#txtInjuryAddress').val() + ', ' + $('#txtInjuryCity').val() + ' ' + $('#txtInjuryState').val() + ' ' + $('#txtInjuryZip').val()); }

• Why do apps from Android 2.1 stop working with 2.2?

  - by poeschlorn

  Hi guys, I've just updated my nexus one to 2.2. Now all of my (own and some from the market) apps throw exceptions and were closed. It's weird, in the app I'm developing atm, there it displays only my start page with buttons, but when I tap on one button to fire an intent to another activity my app gets closed with an exception. Yesterday before the update everything worked fine. The same thing in my emulator: I have two devices, one with API level 7 and one with level 8. Level 7 worked fine, but level 8 killed my app :( What is the problem and how can I solve this? I'm desperatly trying to get it working again :( I hope someone can help me fixing this

• Connecting flex/php to Active Directory

  - by modz0r

  Is there a way to connect my flex web application to Active Directory, and get the logged username? Right now we have a PHP script connected to the flex application, that gets user/pass input from the user and checks if there's such user in the AD, and that the password is correct. I don't want to ask for user/pass, but to make the application get the domain username that connected to it, so I could use it (check if the user has access to my application and such). Is there a way to do so?

• Javascript Methodname is replaced with !==

  - by dasheddot

  Hey! On the server lies a html file with javascript code included. This javascript code includes a method called something like "CheckObject". This file works for all users, except one specific (but important). He gets a javascript error and in his browser sourcode appears something unbelievable: The methodname "CheckObject" is replaced with "Check!==ect", means the "Obj" of the method name is replaced with !==. Why could that be? Hope anybody can help me! Best regards

• Java Wicket - Calling javascript ( JQuery ) before AJAX

  - by user1428051

  I got this thing i'm trying to solve: I got a ListView created using Wicket ( 1.5 ) with a lot of elements and a scroll. When new items are available, the user is asked if he would like to refresh the list via a message backed by an AjaxLink: public void onClick(AjaxRequestTarget ajaxTarget) { /* do something ... */ ajaxTarget.addComponent(_list); } So on click the list gets reloaded and the scroll position is reset to zero. Is there any way i can call JavaScript before the list reloads the save the scroll position? (I know how to get/save the scroll position ( .scrollTop() ) , i just don't know how to call a function right before AJAX ).

• Cant apply color theme to one frame in Emacs?

  - by prtksxna

  This is my emacs file http://pastie.org/1003551. I want the theme to change when I am in shell-mode. But what happens is that the theme gets applied on all the frames. I set the variable color-theme-is-global to nil, but still the same problem is persisting. (add-hook 'shell-mode-hook 'color-theme-monokai-terminal) (set-variable 'color-theme-is-global nil) These are lines 81 and 83 in my .emacs file. What should I do to make it work?

• rails 3.1 partial_updates doesn't seem to work with password

  - by user1306769

  i have a user model with a password attribute, which gets saved as password_digest. What i want to do is have the edit user page and the edit password page separated, so that the admin doesn't need to input the password everytime he needs to change something else. For this i have made an extra action / view. My problem is that when i update the user info, i get password validation errors even though i have no password field in the form. Which leads me to the conclusion that partial_updates isn't working with the password attribute (as i have already tested in the console that it is enabled, and it is) Is this me doing something wrong, or should i approach this differently?

• jQuery won't parse xml with nodes called option

  - by user170902

  hi all, I'm using jQuery to parse some XML, like so: function enumOptions(xml) { $(xml).find("animal").each(function(){ alert($(this).text()); }); } enumOptions("<root><animal>cow</animal><animal>squirrel</animal></root>"); This works great. However if I try and look for nodes called "option" then it doesn't work: function enumOptions(xml) { $(xml).find("option").each(function(){ alert($(this).text()); }); } enumOptions("<root><option>cow</option><option>squirrel</option></root>"); There's no error, just nothing gets alerted, as if the find isn't finding anything. It only does it for nodes called option everything else I tested works ok! I'm using the current version of jQuery - 1.4.2. Anyone any idea? TIA. bg

• Cross version line matching.

  - by BCS

  I'm considering how to do automatic bug tracking and as part of that I'm wondering what is available to match source code line numbers (or more accurate numbers mapped from instruction pointers via something like addr2line) in one version of a program to the same line in another. (Assume everything is in some kind of source control and is available to my code) The simplest approach would be to use a diff tool/lib on the files and do some math on the line number spans, however this has some limitations: It doesn't handle cross file motion. It might not play well with lines that get changed It doesn't look at the information available in the intermediate versions. It provides no way to manually patch up lines when the diff tool gets things wrong. It's kinda clunky Before I start diving into developing something better: What already exists to do this? What features do similar system have that I've not thought of?

• Redirect issues

  - by pinniger

  Whoever wrote the navigation for the site I’m currently working on (classic asp) points the navigation links to a folder, then inside to folder has an index.asp file, so the urls will look something like this www.mysite.com/myfolder/mysubfolder Now, when watch the page load using httpfox, I notice that the first entry is a 302 redirect to the same address with a “/” on the end, so www.mysite.com/myfolder gets redirected to www.mysite.com/myfolder/ (note the / on the end). I’m not to worried that it’s a 302 since its in the admin section of the site, but when I forward the host headers from ISA server, for an https request, its being redirected from https://www.mysite.com/myfolder to http://www.mysite.com:443/myfolder/ and causing all kinds of problems. Anyway, I can’t seem to find any code making this redirect happen, so does IIS 6 do this because the url points to a folder? Or do I need to comb through the code more closely?

• Mesos slave not 'Running' multiple executors simultaneously

  - by user3084164

  I am using Mesos to distribute a bunch of tasks to different machines (mesos-slaves). Here is what happens: 1. My scheduler gets resource offers and accepts it. 2. Mesos stages multiple executors on the same mesos-slaves (each slave has 4 cpus) 3. Only ONE executor enters the 'Running' state on each of the slaves while the others are shown in 'Staging' state. 4. Only after the current executor finishes execution the other executor starts running. Given that I have 4 CPUs on each machine, shouldn't each slave be running 4 executors simultaneously? Each executor requires 1 CPU.

• Best way to test class methods without running __init__

  - by KenFar

  I've got a simple class that gets most of its arguments via init, which also runs a variety of private methods that do most of the work. Output is available either through access to object variables or public methods. Here's the problem - I'd like my unittest framework to directly call the private methods called by init with different data - without going through init. What's the best way to do this? So far, I've been refactoring these classes so that init does less and data is passed in separately. This makes testing easy, but I think the usability of the class suffers a little.

• Switching back into the middle of a function in Actionscript

  - by J.Ded.

  I need to return to my original function after capturing an event (downloading something) with another function. The original function needs to return a value, which depends on the downloaded data. So, I'd like to pause original function for the time needed for the download and the eventhandler function to complete it's work, and resume it afterwards. The obvious way is to set a flag value (both the original function and the eventhandler are within the same class) and make the original function check it until the eventhandler function changes the flag. But that would be wasteful, and my AS is slow enough already:) [other parts of the application utilise some heavy graphics]. Is there another way? Like an event that gets captured "in the middle" of the function? Or some other form of flow control?

• [jQuery] Get width of element after resizing it

  - by infinito

  Hello, Is it possible to get the size of an element after resizing it using $(el).css()? My code is: function resize() { $(".combobox").css('width', '100%'); var width = $(".combobox").width(); } I've get the real value of the combobox only after calling the function a second time. The first time is gets the width before executing $(".combobox").css('width', '100%'); I suppose this is fault of the DOM not being recreated after the .css(). Is there any way to force DOM reloading? Thanks in advance!

• Secure way to run other people code (sandbox) on my server?

  - by amikazmi

  I want to make a web service that run other people code locally... Naturally, I want to limit their code access to certain "sandbox" directory, and that they wont be able to connect to other parts of my server (DB, main webserver, etc) Whats the best way to do it? Run VMware/Virtualbox: (+) I guess it's as secure as it gets.. even if someone manage to "hack".. they only hack the guest machine (+) can limit the cpu & memory the process uses (+) easy to setup.. just create the VM (-) harder to "connect" the sandbox directory from the host to the guest (-) wasting extra memory and cpu for managing the VM Run underprivileged user: (+) doesnt waste extra resources (+) sandbox directory is just a plain directory (?) cant limit cpu and memory? (?) dont know if it's secure enough... Any other way? Server running Fedora Core 8, the "other" codes written in Java & C++

• Order mysql results without identifier

  - by Alex Crooks

  Usually I would have a table field called ID on auto increment. That way I could order using this field etc. However I have no control over the structure of a table, and wondered how to get the results in reverse order to default. I'm currently using $q = mysql_query("SELECT * FROM ServerChat LIMIT 15"); However like I said there is no field I can order on, so is there a way to tell mysql to reverse the order it gets the results? I.e last row to first row instead of the default.

• Comapring pitches with digital audio

  - by user2250569

  I work on application which will compare musical notes with digital audio. My first idea was analyzes wav file (or sound in real-time) with some polyphonic pitch algorithms and gets notes and chords from this file and subsequently compared with notes in dataset. I went through a lot of pages and it seems to be a lot of hard work because existing implementations and algorithms are mainly/only focus on monophonic sound. Now, I got the idea to do this in the opposite way. In dataset I have for example note: A4 or better example chord: A4 B4 H4. And my idea is make some wave (or whatever I don't know what) from this note or chord and then compared with piece of digital audio. Is this good idea? Is it better/harder solution? If yes can you recommend me how to do it?

• SQL: Interrupting a query

  - by NoozNooz42

  I've worked on a project using a proprietary non-SQL DB where queries could be interrupted and in the codebase there were quite some spots where that functionnality was used and made perfect sense (for example to stop a long running query that gets cancelled by the user, or when a more recent query takes place and renders the previous query obsolete, etc.) and I realized I never really saw that kind of "interrupted queries" previously and thought it could make a good SO question (several questions, but they're all related to exactly the same thing): can SQL queries be interrupted? is this part of the SQL standard? if it's not part of the SQL standard, which SQL DBs allow queries to be interrupted (any example most welcome)? is it common to interrupt a DB query (SQL or not) which you'll know you won't care about the result anymore? (in the codebase I've worked on, it sure helps lighten the server's load)

• A little javascript help needed here (easy).

  - by Camran

  function addOption(selectbox, val, txt){ ...... } addOption(list, "Cars", "Cars"); I need to add this in front of the text of the function: &nbsp;&nbsp;&nbsp; So that there is space coming in before the option text...Never mind what it is for, it is just confusing... I just don't know how to insert it into the js code. If I do it like this: addOption(list, "Cars", "&nbsp;&nbsp;&nbsp;Cars"); Then the &nbsp;&nbsp;&nbsp; comes into the text, so it gets displayed for the users. However I need it to be interpreted as "space"... If you don't understand let me know... How can I do this? Quotes, double quotes etc? Thanks

• Can JQuery/JavaScript be used to write a substantial client side application?

  - by Ian

  I have an unusual situation - I have an embedded video streaming device with a complicated UI, and I need to use an embedded web server to reproduce that UI through a web browser. I'm thinking of using JavaScript/JQuery on a C++ backend (I am NOT coding all this myself, I need to hire people for the grunt work). The embedded web server is much less powerful than a PC, so I want to write an application that runs the entire UI in the browser, and only communicates with the server to pass new program settings back and forth, get status updates from the device, and control video playback. In other words, the client gets one big page or a small number of big pages (effectively downloading the application), the application maintains significant local memory storage, and once the pages are first loaded the server never sends anything layout-related. The application has two rows of tabs to navigate ~40 menu pages, drag-and-select controls to pick cells in a grid, sorted lists, lots of standard data entry options, and it should be able to control up to 16 embedded video players at once (preferably VLC). Is this possible in JavaScript/JQuery with a C++ backend?

• How can I update a column in a table with the result of a select statement that uses row being updat

  - by Sailing Judo

  This SQL statement example is very close to what I think I need... update table1 set value1 = x.value1 from (select value1, code from table2 where code = something) as x However, what I need to do is change the "something" in the above example to a value from the row that is being updated. For example, I tried this but it didn't work: update table1 A set value1 = x.value1 from (select value1, code from table2 where code = A.something) as x This is a one time operation to update an existing table and I'm not really looking for high performance way to do this. Any solution that gets the task done is good enough.
