• How to access project files from NUnit tests

  - by Daren Thomas

  I have some Tests that I run with ReSharpers "Run All Tests from Solution" feature. One of the classes being tested has a dependency on a file in the same folder as the assembly containing it. This file is copied to the output directory via MSBuild (set "Copy To Output Directory" to "Copy always"). Problem: The tests are not being run from the normal assembly output directory, but instead some temporary location in my user profile. Therefore, I don't really know where to look for the file - the test runner does not copy it there. Can I force it to?

• Emacs on Windows for C++ development configuration?

  - by rbnn

  Has anyone set up cygwin and some emacs to work well under a 64-bit Windows 7? I tried downloading cygwin recently, and by default not even dired works reliably, there are odd shell prompt characters, I get a lot of warnings, in one case C-c was read as C-g and caused various errors. (Neither xemacs nor emacs worked for me, where by "work" I mean that dired and shell work, and without warnings). I just want the usual emacs development tools: gdb-mode, shell-mode, compiling, tag-search to work as normal. I was hoping someone who has done this recently with cygwin could share whatever relevant shell files, emacs files, environment variables, and so on to make this all work. Should all these things just work out of the box?

• Perl : how to interrupt/resume loop by user hitting a key?

  - by Michael Mao

  Hi all: This is for debugging purpose. I've got a for loop that generates some output to Cygwin bash's CLI. I know that I can redirect outputs to text files and use Perl or even just a normal text editor to inspect the values printed out for a particular iteration, just feel that a bit painful. What I am now thinking is, to place a special subroutine inside the for loop, so that it would be "interrupted" at the beginning of each iteration, and Perl script should only resume to run after user/programmer hits a key(the Enter Key from keyboard?) In this way I can directly inspect the values printed out during each iteration. Is there a simple way to do this, without using additional libraries/CPAN ? Many thanks to the hints/suggestions in advance.

• Preventing a Firefox Extension's load event from triggering across tabs

  - by lgomez

  Hi, I've been working on a Firefox extension that uses an iFrame to do some background scrapping. I have gone through a number of hoops to get it to trigger only once in the window/tab where it should but now when I open a different tab that tab triggers the load event. I found this: https://developer.mozilla.org/en/Code_snippets/Progress_Listeners but the snippets are not there. This was helpful before but doesn't solve the problem: https://developer.mozilla.org/en/Code_snippets/On_page_load More frustrating is that if there is this: https://developer.mozilla.org/En/Listening_to_events_on_all_tabs why should I worry about the normal event listener triggering in more than one tab? Any ideas or examples?

• How to force programs out of swap file when a resources-intensive batch finishes?

  - by sharptooth

  We use employees' desktops for CPU-intensive simulation during the night. Desktops run Windows - usually Windows XP. Employees don't log off, they just lock the desktops, switch off their monitors and go. Every employee has a configuration file which he can edit to specify when he is most likely out of office. When that time comes a background program grabs data for simulation from the server, spawns worker processes, watches them, gets results and sends them to the server. When the time specified by the employee elapses simulation stops so that normal desktop usage is not interfered. The problem is that simuation consumes a lot of memory, so when the worker processes run they force other programs into the swap file. So when the employee comes all the programs he left are luggish and slow until he opens them one by one so that they are unswapped. Is there a way the program can force other programs out of swap file when it stops simulation so that they again run smoothly?

• Profile:Object reference not set to an instance of an object

  - by sallalman83

  Hi, i just lunch my web site i used the asp.net routing technology on it, and its work fine in my localhost but when i moved the project to the hosting server(Godaddy.com) its just work fine when there is no virtual sub directories like this(havebreak.com) but when u click on this link (havebreak.com/Registration/) or any other links that contain a virtual sub-directories its give Object reference not set to an instance of an object error on the profile object if (!Profile.IsAnonymous) Line 18: mlvRegistratioin.ActiveViewIndex = 1; i check my IIS settings and found it using the "Integrated pipeline" as recommended (at least at my knowledge), i checked the httpModules and httpHandlers tags under the system.webServer (since my hosting plan use the IIS7) and under the normal tag and every thing is fine then i used the url-rewriting instead of URL-Routing and the same problem exist and i notice that the session also not working in the virtual sub-directories too and by the way the ASP.NET routing work fine with my site its just the profile and session objects that not workin any help will be appreciated

• Track mass email campaigns

  - by daeliur

  Litmus released an email analytics service last month (may 2010). See here: http://litmusapp.com/email-analytics They boast a very cool "read rate" tracking: they can track normal reads, Skims, and Glanced/Deleted. How can they track skims and glanced/deleted? This to me seems impossible :) They also track forwards and prints. Prints are easy (they include a css @media print query with a bg image). But forwards? I think this might be a combo between subsequent opens and different IPs/reffering URLs. However, this means that if I open my mail and re-read it from another computer, it counts as a forward. Any ideas on this one? To summarize: Litmus Email Analytics says they can track email reads, skims, glanced/deleted, prints and forwards. How do they do it (skims, glanced/deleted and forwards)?

• How do I get user input into a PackageMaker package?

  - by Brian Postow

  I'm trying to create an install package. I've got all my components, and I think I understand most of the process. I want to have an install/set-up script that is run as part of the install. I planned to put it either as a post-install action or a post-install script. The problem is that I need user-input. I can't figure out how to either get user input into the script, or how to add a page in the install UI that has a place for user input and then pass that on to the script. I guess, I could write an apple-script with a dialog to ask the question, and then pass that information on to my shell script (or, write the whole thing in the applescript) but that seems unnecessarily complicated... Is there a normal way to do this? Thanks

• Computer graphics: programatically create duotone (or separations)

  - by TarGz

  There are special kind of images called "duotone" which have just two channels. It is mostly used when you want to achive higher quality reproduction - have a printing press with two colors (black , gray). My question is, I have normal gray-scale image, how to convert it to duotone? I know I can tweak the curves in Photoshop - this is not what I'm asking, rather than how to do it programmatically? Perhaps there is a library which can do just that? What about "dot gain compensation"? "Total ink coverage"?

• Script Speed vs Memory Usage

  - by Doug Neiner

  I am working on an image generation script in PHP and have gotten it working two ways. One way is slow but uses a limited amount of memory, the second is much faster, but uses 6x the memory . There is no leakage in either script (as far as I can tell). In a limited benchmark, here is how they performed: -------------------------------------------- METHOD | TOTAL TIME | PEAK MEMORY | IMAGES -------------------------------------------- One | 65.626 | 540,036 | 200 Two | 20.207 | 3,269,600 | 200 -------------------------------------------- And here is the average of the previous numbers (if you don't want to do your own math): -------------------------------------------- METHOD | TOTAL TIME | PEAK MEMORY | IMAGES -------------------------------------------- One | 0.328 | 540,036 | 1 Two | 0.101 | 3,269,600 | 1 -------------------------------------------- Which method should I use and why? I anticipate this being used by a high volume of users, with each user making 10-20 requests to this script during a normal visit. I am leaning toward the faster method because though it uses more memory, it is for a 1/3 of the time and would reduce the number of concurrent requests.

• How RPG characters are made

  - by user365314

  If RPG with the ability to change armors and clothes are made, how is it done? I mean the 3d side mostly If i make normal character, that has flat clothes, it would be easy, just change textures, but question is about armors, which have totally different models. So are only armor models recreated or character model with armor? How is it imported into game engine, only armor or character model with new armor? If person changes armor in game, will game swap the hole model or only the armor part? if only the armor part, then how the movement animations are done, are armor models animated on characters in 3d programs or what... :D

• Explain a block of crazy JS code inside Sizzle(the CSS selector engine)

  - by Andy Li

  So, here is the function for pre-filtering "CHILD": function(match){ if ( match[1] === "nth" ) { // parse equations like 'even', 'odd', '5', '2n', '3n+2', '4n-1', '-n+6' var test = /(-?)(\d*)n((?:\+|-)?\d*)/.exec( match[2] === "even" && "2n" || match[2] === "odd" && "2n+1" || !/\D/.test( match[2] ) && "0n+" + match[2] || match[2]); // calculate the numbers (first)n+(last) including if they are negative match[2] = (test[1] + (test[2] || 1)) - 0; match[3] = test[3] - 0; } // TODO: Move to normal caching system match[0] = done++; return match; } The code is extracted from line 442-458 of sizzle.js. So, why is the line var test = ..., have the exec inputing a boolean? Or is that really a string? Can someone explain it by splitting it into a few more lines of code?

• Resizable Button with background in flash CS4

  - by Bhavesh.Bagadiya

  Hi, I want to create a button which resize dynamically with content. to achieve this, I created a MovieClip in library and added four layers into it namely - text, bg, shadow and border. Problem I'm having is, if I make textfield autosize, only textfield resizes and others stuff remain as it is. if I calculate width required using xxxLineMetrics function and apply it to Button, background resizes properly but textfield also stretches with them and looks ugly. I want backgrounds(sibling of textfield) resize properly with textfield so button looks nice with resized background and normal autosized textfield. I hope u guys got what I want...any help appreciated... Thanks,

• does windows 7 bluetooth stack and API support connection of headsets

  - by markh44

  We need to write code to search for, pair and connect to a bluetooth headset with Windows 7 Embedded. Once connected the headset will be used as a normal windows audio device. We fully control what software is installed on the system so conflicting stacks and similar concerns are not a problem. We would however like to minimize as far as possible installing extra software such as 3rd party stacks. Therefore my question is: can the built in windows 7 bluetooth stack and C++ API alone be used to create the functionality we need?

• Imagick: gifs, and background color

  - by TheButch3r

  Hi, I have 2 questions about using the php imagick class that I can't get working properly... 1.) I tried resizing / cropping a gif, and treated it as a normal image. It seemed to work, except that a few frames in the middle of the animation contained a small patch of artifacts. Is there a setting that should be used when working with multi-frame gifs? 2.) Is there a simple command to resize images if they are too small by just adding a background? For instance, if an image is 10x10, could I add a white background, and have a 100x100px image with the original in the upper left corner? Thanks for any help!

• Create categorical variable in R based on range

  - by Stedy

  I have a dataframe with a column of integers that I would like to use as a reference to make a new categorical variable. I want to divide the variable into three groups and set the ranges myself (ie 0-5, 6-10, etc). I tried cut but that divides the variable into groups based on a normal distribution and my data is right skewed. I have also tried to use if/then statements but this outputs a true/false value and I would like to keep my original variable. I am sure that there is a simple way to do this but I cannot seem to figure it out. Any advice on a simple way to do this quickly?

• best way to output a full precision double into a text file

  - by flevine100

  Hi, I need to use an existing text file to store some very precise values. When read back in, the numbers essentially need to be exactly equivalent to the ones that were originally written. Now, a normal person would use a binary file... for a number of reasons, that's not possible in this case. So... do any of you have a good way of encoding a double as a string of characters (aside from increasing the precision). My first thought was to cast the double to a char[] and write out the chars. I don't think that's going to work because some of the characters are not visible, produce sounds, and even terminate strings ('\0'... I'm talkin to you!) Thoughts?

• How do I send telnet option codes?

  - by Matt

  I've written a socket listener in Java that just sends some data to the client. If I connect to the server using telnet, I want the server to send some telnet option codes. Do I just send these like normal messages? Like, if I wanted the client to print "hello", I would do this: PrintWriter out = new PrintWriter(clientSocket.getOutputStream()); out.print("hello"); out.flush(); But when I try to send option codes, the client just prints them. Eg, the IAC char (0xff) just gets printed as a strange y character when I do this: PrintWriter out = new PrintWriter(clientSocket.getOutputStream()); out.print((char)0xff); out.flush();

• Is there a way to set the minHeight of the scroll bar thumb in Flex 3

  - by Mad Oxyn

  In my project we needed to make the scollbars look like Windows scrollbars. Therefore I have a thumbIcon on the thumb of a vertical scrollbar, but if I get too many items in the combobox, the scrollbar gets fiddly. This is because the margin between the thumbIcon and the border of the thumbSkin is too small. Is there a way to set the minimum height of the thumbSkin so that I can ensure there is always a margin there and it always looks good, even if there are too many items? Image above, see the thumb? By the thumbIcon I mean the 3 horizontal lines. The top and bottom margin between this icon and the border of the thumb itself is too small. This is the normal scroll bar, the thumbIcon and the borders of the thumb have enough margin, which make the scroll bar look a lot better.

• Making JSON Feed Work Server to Server

  - by Oscar Godson

  I have a JSON feed (which I don't directly control, I have to ask the server admins to update it), that is returning NULL, or otherwise not working when I try to access it from another server. The actual feed works fine, but I can't get it to work like a normal API. Why can I use Flickr, WhitePages, Twitter, etc's JSON APIs, but for: http://portlandoregon.gov/shared/cfm/json.cfm It returns NULL in the browser when using JS. If I call it on the same server, it's fine though. If this is a server issue, what do I ask the admins to change, and if this is a local (browser) based issue, what am I doing wrong for this one feed that works for every other JSON API?

• C#: Replicating keyboard shortcuts in textbox, how do I prevent the beep sound caused by alt key pre

  - by Michael Johnson

  I'm creating a routine that allows the user to replicate keyboard shortcuts into a textbox for 'custom keyboard shortcuts' customization, but everytime the alt key is pressed with another letter, it produces another sound. I'm capturing the keys in the textbox_keydown event to parse the modifiers + other keys into a readable Shift + A or Ctrl + Shift + B manner into that very same textbox. Should I be doing this in a different event like textbox_previewkey instead of textbox_keydown? How can I prevent the alt modifier key + a letter or number causing the Beep sound? the textbox is just a normal .net 3.5 textbox with the only edited properties of it being the ReadOnly property to false. Is there a better way I could re-do this? I'm currently just checking that if any modifiers keys are pressed and then + a-z or 0-9, then to go ahead and input the appropriately pressed keys into that same textbox like Shift + A or Ctrl + Shift + Y.

• does a ruby on rails rack class get access to the entire rails environment?

  - by Andrew Arrow

  that is when the def call(env) method is invoked by hitting any url, can I inside that method make some ActiveRecord queries, use classes defined in lib, etc. etc. Or is it more like an irb console without the rails env loaded? Another way to put it with a rake task example: task :foo => :environment do # with env end task :foo2 do # without env end I would think rack classes would NOT get the environment so they are super fast and don't take all the overhead of a normal rails request. But that doesn't seem to be the case. I CAN make ActiveRecord queries inside my rack class. So what is the advantage of rack then?

• How to get coordinates when iPhone is locked/sleeping?

  - by lionfly

  For normal situations, the didUpdateToLocation (of CLLocationManager) does not work any more when the lock/sleep button is pushed, and your app cannot get further newLocation coordinates during the locked period. However, some apps CAN track during the locked period, and they will show the correct route when you unlocked and see the Mapview. Obviously there are ways to get the coordinates during the locked period. How to get the coordinates when the iPhone is locked/sleeping? Who has hints and further info, please post. Thanks.
