  • SASS color array

    - by Eric Holmes
    I am trying to write a loop that will cycle through colors and condense the amount of code in my scss file. Here is a simple example of what I have: $color1: blue; $color2: red; $color3: white; $color4: black; .color1-bg { background-color: $color1; } .color2-bg { background-color: $color2; } .color1-border { border-color: $color1; } .color2-border { border-color: $color2; } And so on. I am looking for a way to make the equivalent of a foreach loop, and cycle through an 'array' of colours by index. Something like this: @each $color in $color1, $color2, $color3, $color4 { .{$color}-bg { background-color: $color; .{$color}-border { border-color: $color; } I know the syntax is wrong, but that is my thinking process. Thanks for the help!

  • A way to ensure that a system tray icon is removed... guaranteed

    - by Brian R. Bondy
    Is there a way to guarantee that your system tray icon is removed? To add the system tray icon you do: Shell_NotifyIcon(NIM_ADD, &m_tnd); To remove the system tray icon you do: Shell_NotifyIcon(NIM_DELETE, &m_tnd); What I want to know: what if you application crashes? The icon stays in your system tray until you mouse over. Is there a way to guarantee that the icon will be removed, even when the application crashes? I would prefer not to use structured exception handling for various reasons. Another case that I want to handle is when the process is killed, but doesn't necessarily crash.

  • How to detect an active x component that does not respond any more?

    - by koschi
    My application is written in C++ and uses the Qt framework. I use the QAxWidget class to access an active x component. Now I need some kind of mechanism that notifies my application each time the active x component has crashed or does not respond any more (due to dead lock or infinite loop). (1) can easily been done by watching the external process of the active x component. But maybe there is a more elegant approach? But how can (2) be implemented?

  • get n records at a time from a temporary table

    - by Claudiu
    I have a temporary table with about 1 million entries. The temporary table stores the result of a larger query. I want to process these records 1000 at a time, for example. What's the best way to set up queries such that I get the first 1000 rows, then the next 1000, etc.? They are not inherently ordered, but the temporary table just has one column with an ID, so I can order it if necessary. I was thinking of creating an extra column with the temporary table to number all the rows, something like: CREATE TEMP TABLE tmptmp AS SELECT ##autonumber somehow##, id FROM .... --complicated query then I can do: SELECT * FROM tmptmp WHERE autonumber>=0 AND autonumber < 1000 etc... how would I actually accomplish this? Or is there a better way? I'm using Python and PostgreSQL.

  • Final Integration Testing for Q.A.

    - by CalebHC
    A medium sized rails app that our company has been working on is getting close to the end of development and we are going to start doing Q.A. testing on it. We've have been writing unit, functional and integration tests all along and our test coverage is about 99% (even though that really doesn't mean anything). We feel like we have a pretty good test suite but I was wondering if we should be writing final integration tests for every little action we are going to do during our Q.A. process. If so, would using Shoulda or Cucumber be a good idea? We haven't used either of those testing tools yet, but they sound really great. Any ideas or thoughts would be really helpful. Thanks

  • Core Data No Longer Updating Sqlite Schema

    - by nefsu
    I am using core data for my app and I never had any problems adding or removing columns until recently. But now even if I make changes to my xcdatamodel and generate new and updated entity h/m files, sqlite doesn't seem to be picking up the changes. I actually went over to the documents folder and inspected the create statement for the relevant tables in sqlite3 and I was able to confirm that the columns I added were missing. I removed and redeployed the app several times to no avail. Is it possible to do something to the app to make it disregard any schema changes being made through xcdatamodel? I guess another thing I should mention is I recently started putting my entire projects folder in CVS so I wonder if something got messed up in the checkin and check out process.

  • Manage build target variables in iphone project

    - by DougW
    We're transitioning to an automated build process for our iphone projects. These projects can be checked out by individual devs, in which case all the API URLs need to point to a certain path. There are also a variety of build environments, each with their own API root paths. I could probably add multiple, different build targets, and have each of them include a different URLs definition file, but this seems like a lot of upkeep and a bit overkill. Any best practices out there for swapping a few environmental variables for different build environments without much fuss?

  • Scripting vim to Run Perltidy on a Buffer

    - by rjray
    At my current job, we have coding-style standards that are different from the ones I normally follow. Fortunately, we have a canned RC file for perltidy that I can apply to reformat files before I submit them to our review process. I have code for emacs that I use to run a command over a buffer and replace the buffer with the output, which I have adapted for this. But I sometimes alternate between emacs and vim, and would like to have the same capabilities there. I'm sure that this or something similar is simple and had been done and re-done many times over. But I've not had much luck finding any examples of vim-script that seem to do what I need. Which is, in essence, to be able to hit a key combo (like Ctrl-F6, what I use in emacs) and have the buffer be reformatted in-place by perltidy. While I'm a comfortable vim-user, I'm completely clueless at writing this sort of thing for vim.

  • jQuery .each() with Array

    - by John Crain
    Basically, I am trying to gather the IDs of every element with a specific class and place those IDs into an array. I'm using jQuery 1.4.1 and have tried using .each(), but don't really understand it or how to pass the array out of the function. $('a#submitarray').click(function(){ var datearray = new Array(); $('.selected').each(function(){ datearray.push($(this).attr('id')); }); // AJAX code to send datearray to process.php file }); I'm sure I'm way off, as I'm pretty new at this, so any advice help would be awesome. Thanks!

  • Google Maps API v3.9: Blurry custom markers when zooming

    - by Mike
    So it appears that Google have fixed the blurry map issue with the 3.9 / 3.10 API, which is great. But there's a new one with custom markers. As soon as you zoom in one level, the custom markers become corrupted / blurry. They rectify themselves if zooming out, although the process of zooming out also makes the markers slightly blurry. The 3.8 API does not exhibit this problem with custom markers. Here's a picture illustrating the problem (I suggest you open the image in a new tab; the blurriness isn't as easily visible when the image is scaled to fit this post). The blurring is most noticeable with the straight lines of the paper crane marker: I've had a prod through the HTML, but I can't really tell how the markers are placed on the map. But I thought that I'd put this issue out there for anyone who has experienced similar, or if anyone has any thoughts on how this can be resolved, save waiting to see if it's a glitch in the API.

  • Millisecond-Accurate Scheduling of Future Events in C++/CLI

    - by A Grad Student at a University
    I need to create a C++/CLI mixed assembly that can schedule future calls into a native DLL with millisecond accuracy. This will, of course, mean setting a timer (what kind?) for a millisecond or three beforehand, then spinning until the moment and calling the native DLL function. Based on what I've read, I would guess that the callback that the timer calls will need to be native to make sure there are no thunks or GC to delay handling the timer callback. Will the entire thread or process need to be native and CLR-free, though, or can this be done just as accurately with #pragma unmanaged or setting one file of the assembly to compile as native? If so, how? If there is indeed no way to do this in mixed-mode C++/CLI, what would be the easiest way to set up an app/thread (ie, DLL or exe?) to handle it and to get the data back and forth between the native and managed threads/apps?

  • integrating facebook auth into my web form app

    - by user169692
    Hi, I would like to allow my users to authorise my app with their fb on registration. All of the examples i see redirect users to the fb canvas page after authorisation, but i only want this to be a step in the registration process. Essentially, i want an icon they can click that would open up a new window where they can login to fb and a simple postback to the registration page where i would detect the login and hide the login button. Any ideas on how I can achieve this using the facebook c# sdk? Thanks and Merry Christmas :)

  • DVCS - What's the downside of rewriting unpublished history?

    - by user1447278
    I was wondering what in particular is the downside of "losing history" in a development process. One famous example is of course git rebase -i / git merge --squash, but also what is described here: http://fourkitchens.com/blog/2009/04/20/alternatives-rebasing-bazaar under "I want to clean up my commit history prior to submitting my changes to the mainline." I can see that exporting patches and applying them to another branch would lose the "history" of the branch, but why would that branch and its commit history be useful after it has been merged? Can someone elaborate on why such techniques are considered "dirty"? Why does it matter in which order changes were originally committed in the first place as long as they can be applied to the main branch?

  • Is it possible to talk to the iPhone simulator/device.

    - by Plumenator
    I need to automate the build/deploy process for my iphone applications from a script. I can use xcodebuild to build the project, then use Applescript to deploy and debug/run the application. Assuming the application will stop by itself after a while, I need to collect the generated logs for verification. But the problem is I have no way to know when the application ended from outside of the application itself. If the running time is fixed, I can again use Applescript to stop the application (Cmd+Shift+Enter). So there has to be a way to connect to the device/simulator and wait on the application somehow.

  • How do I completely disable caching in Cakephp?

    - by James Lamiell
    So I opened the cache floodgates in my Cakephp app and now I want to close them... I've done pretty everything I can: delete all files in the tmp folder (but not the folders), turned 'Cache.disable' on in the core.php file in my app, have tried clearing the cache from within some controllers with clearCache() and Cache::clear() (but I suspect this doesn't work because it's not loading the controller -- due to caching). I've pretty much effectively halted my development process just because caching won't turn off. Anyone have some ideas that I could try? I'm starting to think it may be within the browser or maybe my hosting service, but it's probably just Cakephp messing with me.

  • prevent linux thread from being interrupted by scheduler

    - by johnnycrash
    How do you tell the thread scheduler in linux to not interrupt your thread for any reason? I am programming in user mode. Does simply locking a mutex acomplish this? I want to prevent other threads in my process from being scheduled when a certain function is executing. They would block and I would be wasting cpu cycles with context switches. I want any thread executing the function to be able to finish executing without interruption even if the threads' timeslice is exceeded.

  • Can Visual Studio exclude certain folders when searching for header files?

    - by identitycrisisuk
    I'm having trouble with a library that we are using, which has two copies of header files that are needed - one which we are modifying and building from and another which is automatically created during the build process. I don't fully know why or really want to change this but it can cause a bit of annoyance when on random occasions the go to definition function takes you to the auto created header instead of the one used to build. Usually you can spot it but sometimes you don't and make changes to the auto created one, which are then overwritten or sometimes stay around for a while so that something works on your machine but breaks on other peoples. I don't know if there is any way around this as the auto created folder is in the additional include directories of some of the projects in the solution but I just thought I would ask if there was any good way of reducing the chance of this annoying situation cropping up.

  • content management system

    - by Farax
    I am building a website for a client who needs a content management system to go with it. The client requires features such as content staging, approving process before publishing a page, provision for templates (changing which changes the lay out for the whole website), entry and expiry dates for pages and content search. I am planning to use an existing opensource CMS for the work but I am confused as to which one should it be. I need help in deciding whether this approach is good or should i develop my own CMS? and if I do use an opensource one, which one is extensible and customisable enough using .NET?

  • Dynamic creation of a pointer function in c++

    - by Liberalkid
    I was working on my advanced calculus homework today and we're doing some iteration methods along the lines of newton's method to find solutions to things like x^2=2. It got me thinking that I could write a function that would take two function pointers, one to the function itself and one to the derivative and automate the process. This wouldn't be too challenging, then I started thinking could I have the user input a function and parse that input (yes I can do that). But can I then dynamically create a pointer to a one-variable function in c++. For instance if x^2+x, can I make a function double function(double x){ return x*x+x;} during run-time. Is this remotely feasible, or is it along the lines of self-modifying code?

  • Visual C++ 9 Linker file size limitation.

    - by Raindog
    It appears that the visual C++ 9 linker has a file allocation algorithm that doubles the size of the file every allocation, so you get 512mb, 1024mb, 2048mb, 4096mb. The problem is that it is using a library that cannot handle files larger 2048MB, and as such crashes with an error such as "cannot read file at is the disk full or write protected". Is there a way to bypass this limitation or otherwise replace the linker with something else that works? A bit of background, I have a code generator that generates a large number of files, ~15k cpp files, I've managed to reduce the number of files to something about 6k to get something that at least completes the linking process, I would like to be able to include all 15k without having to create multiple libs.

  • TFS get command erroneously returns "All files are up to date."

    - by NathanE
    We are just in the process of migrating our TFS repo to Mercurial as we've had enough of TFS. Unfortunately TFS has thrown us one last curve ball before it lets us go. We've wrote a script that we intend to have "get" each changeset (including timestamp, check-in comment etc) and then add them to the Mercurial repo and check it in. Unfortunately TFS is acting very strange when we execute the tf get * /version:C111 /overwrite command. It immediately returns "All files are up to date." But this is impossible. The workspace folder is empty! And viewing the details for the 111 changeset quite clearly shows that the changeset contains "stuff" i.e. the repo is certainly not empty. What could be causing this?

  • Stringification of a macro value

    - by SF.
    I faced a problem - I need to use a macro value both as string and as integer. #define RECORDS_PER_PAGE 10 /*... */ #define REQUEST_RECORDS \ "SELECT Fields FROM Table WHERE Conditions" \ " OFFSET %d * " #RECORDS_PER_PAGE \ " LIMIT " #RECORDS_PER_PAGE ";" char result_buffer[RECORDS_PER_PAGE][MAX_RECORD_LEN]; /* ...and some more uses of RECORDS_PER_PAGE, elsewhere... */ This fails with a message about "stray #", and even if it worked, I guess I'd get the macro names stringified, not the values. Of course I can feed the values to the final method ( "LIMIT %d ", page*RECORDS_PER_PAGE ) but it's neither pretty nor efficient. It's times like this when I wish the preprocessor didn't treat strings in a special way and would process their content just like normal code. For now, I cludged it with #define RECORDS_PER_PAGE_TXT "10" but understandably, I'm not happy about it. How to get it right?

  • a question related to Google Translate

    - by Robert
    Hi all, it works perfectly fine if I paste the following URL directly into my IE address bar: http://translate.google.cn/translate?hl=zh-CN&sl=zh-CN&tl=en&u=http%3A%2F%2Fnews.baidu.com%2Fns%3Fword%3D%25B0%25C2%25B0%25CD%25C2%25ED it will translate some Chinese news pages into English ones. but if I call this address in a Java program like: Process q=Runtime.getRuntime().exec("cmd /c start http://translate.google.cn/translate?hl=zh-CN&sl=zh-CN&tl=en&u=http%3A%2F%2Fnews.baidu.com%2Fns%3Fword%3D%25B0%25C2%25B0%25CD%25C2%25ED"); It will only return to the Google translate main page. Wonder what went wrong there. and it would be great if you help me how to realize this(opening the Google translated result page simplying by supplying the URL,in a Java program). Many thanks.

  • Creating a WCF Restful service, concurrency issues

    - by pmillio
    Hi i am in the process of creating a restful service with WCF, the service is likely to be consumed by at least 500 people at any given time. What settings would i need to set in order to deal with this. Please give me any points and tips, thanks. Here is a sample of what i have so far; [ServiceBehavior(IncludeExceptionDetailInFaults = true, InstanceContextMode = InstanceContextMode.Single, ConcurrencyMode = ConcurrencyMode.Multiple)] And this is an example of a method being called; public UsersAPI getUserInfo(string UserID) { UsersAPI users = new UsersAPI(int.Parse(UserID)); return users; } [OperationContract] [WebGet(BodyStyle = WebMessageBodyStyle.Bare, ResponseFormat = WebMessageFormat.Json, UriTemplate = "User/{UserID}")] [WebHelp(Comment = "This returns a users info.")] UsersAPI getUserInfo(string UserID);
