• soft stoppped working

  - by Jack Morton

  this is might be really weird, but I have no idea what kinda wizardry of this. Basically, my Visual Studio stopped responding to my changes, it stopped building solution. I can comment code, which would completely ruin the logic of program, and Visual Studio will still run program that I guess it has in memory. It's really annoying, and I have no idea what it is. I keep restarting software, but it's still does the same. It's a licensed software. I was wondering If someone knew what was going on. Thanks!

• Storyboard changing controller (modal) not working

  - by BrandNew

  I have problem with navigation between ViewControllers: here is my storyboard: http://postimg.org/image/dar9pkuvl/ The navigation between controllers in green rectangle works fine, I add to controller number 1 controller number 2 (by addtosubview) and then controllers number 3,4,5 to UIScrollView in controller number 2 ( controller number 2 contain scrollview). Everything work fine but if I click Send buttn on controller 4 nothing happens (It is strange because I was added connection between button and controller in the same way like between controllers 7 and 8). I know it is little bit confusing described, but I hope that someone tell me where is problem. Thanks

• How to call a function from a shared library?

  - by Frank

  What is the easiest and safest way to call a function from a shared library / dll? I am mostly interested in doing this on linux, but it would be better if there were a platform-independent way. Could someone provide example code to show how to make the following work, where the user has compiled his own version of foo into a shared library? // function prototype, implementation loaded at runtime: std::string foo(const std::string); int main(int argc, char** argv) { LoadLibrary(argv[1]); // loads library implementing foo std::cout << "Result: " << foo("test"); return 0; } BTW, I know how to compile the shared lib (foo.so), I just need to know an easy way to load it at runtime.

• Creating a "Universities Attended" Profile field/block (Drupal)

  - by Frank0051

  Interesting question for everyone. So I have am thinking of adding a "university attended" field to the profile page of members in Drupal. I guess I am trying to figure out the best way to go about it. I was originally thinking of a text field, but than I thought you could get multiple instances of of university names, making it hard to sort people by school (ie. UF, University of Florida, Florida, U of F, etc). I then began to think about creating a drop down, but I wasn't quite sure where I could get a listing of all the schools. Perhaps I could find a database population that a site like LinkedIn or Facebook uses. Then I thought of what happens when someone has attended multiple schools, how would I account for that? So, I guess I wanted to pose the question of how would you go about adding a University(ies) attended field to profile pages if you had to design a site to do so?

• Run and terminate a prgram (Python under Windows)

  - by Fredrich

  I'd like to create a small script to that basically does this: run program1.exe -- kill program1.exe after n seconds -- run program1.exe again. I know some basic Python and would read up on this, but I'm in a bit of a hurry and just need this to get done asap. If someone has a script/idea or could help my out with just the syntax I need to open and kill the .exe file, please... I don't mind solutions in other languages either. I'm sorry if this is a bit "please write my code"-ish, that's not something I typically do.

• Applying transformations to NSBitmapImageRep

  - by Adam

  So ... I have an image loaded into an NSBitmapImageRep object, so I am able to examine the contents of specific pixels via a two dimensional array. Now I want to apply a couple of "transformations" to the image, in preparation for some additional processing. If I was manipulating the image manually, in Photoshop, I would: Rotate the image Crop a portion of it and discard the rest Apply a "threshold" transformation (which essentially converts the image to black and white, based on the threshold value I provide) Resample the image to shrink it down a bit (which, although losing some image quality, will speed up the subsequent processing) (not necessarily in that order) Are there objective C methods available to facilitate these specific image manipulations, with the data in the NSBitmapImageRep object? If so, can someone point me to some good examples?

• Is it a good idea to apply some basic macros to simplify code in a large project?

  - by DoctorT

  I've been working on a foundational c++ library for some time now, and there are a variety of ideas I've had that could really simplify the code writing and managing process. One of these is the concept of introducing some macros to help simplify statements that appear very often, but are a bit more complicated than should be necessary. For example, I've come up with this basic macro to simplify the most common type of for loop: #define loop(v,n) for(unsigned long v=0; v<n; ++v) This would enable you to replace those clunky for loops you see so much of: for (int i = 0, i < max_things; i++) With something much easier to write, and even slightly more efficient: loop (i, max_things) Is it a good idea to use conventions like this? Are there any problems you might run into with different types of compilers? Would it just be too confusing for someone unfamiliar with the macro(s)?

• Is there a program devleopment environment similar to visual studios?

  - by Assimilater

  I'm getting really tired of working against click-once and I'm wondering if there's a better alternative. I'm looking for a programming environment that preferably does not depend on the .net framework. I'm not sure how much .net does for me exactly (though I have some idea) but I'd like to make my programs as independent of downloading a microsoft or other framework. I often think of professional programs like itunes, gimp or firefox that don't require someone to have a .net framwork. I'd also like to have these programs work on windows mac and linux. Any suggestions?

• Ruby on Rails: Is there a way to tell what fields failed validation in ActiveRecord?

  - by randombits

  I'm attempting to create an XML builder file that tells a user to know exactly what fields failed validation in the output. I also want to display their input back to them, so that requires me figuring out which fields failed validation. Meaning if someone fails on creating a new user resource, I want to display XML that's meaningful (Besides a meaningful HTTP status number) such as: <errors> <user> <email>bad@email: Invalid email format</email> </user> <errors> The above is tough to do in an XML builder file without knowing what field failed. And if I just iterate over error messages, I won't know how to prob my @user object to get the value that the user supplied.

• PHP - Can you help change this function slightly?

  - by Joe

  I have the following function I modified based off someone elses function: function showCombinations($string, $nameString, $linkParts, $i){ $wordDivider = "/"; //the divider between the words/values if ($i >= count($linkParts)){ echo "<a href='".trim($string)."'>".trim($nameString)."</a>, "; } else { foreach ($linkParts[$i] as $currentTrait){ if ($currentTrait['name']=="urltext"){ $currentNameStringName=""; //ignore } else { $currentNameStringName=$currentTrait['name']; } if ($nameString!=""){ $currentNameString=$nameString." - ".$currentNameStringName; } else { $currentNameString=$nameString.$currentNameStringName; } showCombinations($string.$currentTrait['value'].$wordDivider, $currentNameString, $linkParts, $i + 1); } } } showCombinations('', '', $linkParts, 0); All I need to change this to do is, instead of "ECHO", I want it to build up the combination and so I can do: $result = showCombinations('', '', $linkParts, 0); echo $result; I need it this way because I have to modify that $result, not just echo it.

• Htaccess/robots.txt to allow search bots to explore main domain but not directory on other domain

  - by gX

  Ok, I understand the Title didn't make any sense so here I've tried to explain it in detail. I'm using a hosting that gives me space for my domain and lets me "add on" other domains on it. So lets say I have a domain A, and I add on a domain B. Basically my hosting gives me a public_html where I can put stuff that shows when someone visits website A. But, when I add the domain B, it lets me put the content of B, INSIDE of that public_html so that website B.com can also be visited by going to A.com/siteB... Thats all good, except that Google has started indexing B.com as well as A.com/siteB, I'm ok with it indexing B.com, but I somehow want to prevent it from indexing A.com/siteB so that when people search for B, it doesn't end up showing A.com/siteB. Any ideas? Let me know if the question is still unclear.

• How to get a 3D picture in an iphone app?

  - by wolverine

  In an application, i saw that they used to display pictures of vehicles. But what was amazing was when we touch and swipe in that picture, it rotates in 3d way left and right. And from the front view we can rotate and get to see its back view also. It is a very good feature and i was trying to replicate it. But couldnt get an idea of how and where to start. My doubts are Whats the actual format of the thing, it surely isn't a picture. How do they get to rotate it? Could someone give me an idea where i should start or where I should look upon?

• How to create url preview in javascript?

  - by Razor Storm

  Can someone help me with creation of a url preview script in javascript? What I mean is this. Say I have a link on my site, I want the user to be able to mouse over the link, and have an image pop up that shows what the target of the link looks like. Don't worry about the css, I got that working, I just need the actual script to show the image. Currently I am doing it by showing up an iframe that actually renders the page, but this is not scalable and looks ugly. No, having the page display premade images is not an option, since the links will be linking to dynamically generated user content. thanks

The constant was appended to at the same time the local variable was. Known behavior? Expected?

• Commands implicitly threaded in Makefiles ?

  - by apple92

  Hi, I have a "super" makefile which launches two "sub" make file: libwebcam: @echo -e "\nInvoking libwebcam make." $(MAKE) -C $(TOPDIR)/libwebcam uvcdynctrl: @echo -e "\nInvoking uvcdynctrl make." $(MAKE) -C $(TOPDIR)/uvcdynctrl uvcdynctrl uses libwebcam... I noticed that those two builds are launched as separate threads by make ! Thus sometimes the lib is not available when uvcdynctrl starts being built, and I get errors. By default, make should not launch commands as threads since this is available only through -j (number of jobs) and, according to the make manual, there is no thread by default. I run this on an Ubuntu. Did someone face the same issue ? Apple92

• How to send link/url to confirm user registration and/or password reset/recovery using ASP.Net MVC2?

  - by Mark_DVM_Software

  Hi, I see it all over the place, yet, I could not find one example about this (maybe I don't know the proper wording), I am trying to build using ASP .Net MVC2 (but any example on just ASP .Net would be also helpful) a process that will send a link to the user at the end of the registration process to let him confirm his registration. Also, a similar process to let the user to reset his password, with the typical "forgot password" and send a link/url so that the user can click and type a new password. Can someone help me to either find an example or at least to let me know how to "google" it? Thanks, Mark
