  • Boost.Program_options fixed number of tokens

    - by kloffy
    Boost.Program_options provides a facility to pass multiple tokens via command line arguments as follows: std::vector<int> nums; po::options_description desc("Allowed options"); desc.add_options() ("help", "Produce help message.") ("nums", po::value< std::vector<int> >(&nums)->multitoken(), "Numbers.") ; po::variables_map vm; po::store(po::parse_command_line(argc, argv, desc), vm); po::notify(vm); However, what is the preferred way of accepting only a fixed number of arguments? The only solution I could come is to manually assign values: int nums[2]; po::options_description desc("Allowed options"); desc.add_options() ("help", "Produce help message.") ("nums", "Numbers.") ; po::variables_map vm; po::store(po::parse_command_line(argc, argv, desc), vm); if (vm.count("nums")) { // Assign nums } This feels a bit clumsy. Is there a better solution?

  • how to iterate through multiple select options with jquery

    - by amir
    I was just wondering if it's possible to go through multiple select options and get their values and text(if one is selected get the value and text, if 2 is selected get both of their values and text and so on) I have 15 select boxes in one page? any help would be appreciated. <form> <select class="select" name="select3" id="select3"> <option value="0">0</option> <option value="1.99">1</option> <option value="1.99">2</option> <option value="1.99">3</option> <option value="1.99">4</option> <option value="1.99">5</option> <option value="1.99">6</option> <option value="1.99">7</option> <option value="1.99">8</option> </select> </form> <form> <select class="select" name="select" id="select"> <option value="0">0</option> <option value="1.99">1</option> <option value="1.99">2</option> <option value="1.99">3</option> <option value="1.99">4</option> <option value="1.99">5</option> <option value="1.99">6</option> <option value="1.99">7</option> <option value="1.99">8</option> </select> </form> all the select options have the same class. thanks

  • Force chart labels to remain inside frame

    - by adolf garlic - SAVE BBC6MUSIC
    RS2008 - pie chart I have 'outside' labels with lines pointing to the segment (although strangely this only appears to work in pdf output) However (see pic below) the label is appearing outside the scope of the chart area How can I force it to remain inside? (MinimumRelativePieSize is set to 70) (pic below missing due to not being able to find an image host that isn't blocked by corp firewall) Picture a pie chart of 25 slices, with radial lines that project through the sides. The line from each slice then becomes horizontal, before disappearing outside. (above actually fits tune of "Lucy in the Sky with Diamonds")

  • How to persist options selected in AlertDialog spawned from ItemizedOverlay onTap method

    - by ahsteele
    In the description of how to add a list of options to an AlertDialog the official Android documentation alludes to saving a users preferences with one of the "data storage techniques." The examples assume the AlertDialog has been spawned within an Activity class. In my case I've created a class that extends ItemizedOverlay. This class overrides the onTap method and uses an AlertDialog to prompt the user to make a multi-choice selection. I would like to capture and persist the selections for each OverlayItem they tap on. The below code is the onTap method I've written. It functions as written but doesn't yet do what I'd hope. I'd like to capture and persist each selection made by the user to be used later. How do I do that? Is using an AlertDialog in this manner a good idea? Are there better options? protected boolean onTap(int index) { OverlayItem item = _overlays.get(index); final CharSequence[] items = { "WiFi", "BlueTooth" }; final boolean[] checked = { false, false }; AlertDialog.Builder builder = new AlertDialog.Builder(_context); builder.setTitle(item.getTitle()); builder.setMultiChoiceItems(items, checked, new DialogInterface.OnMultiChoiceClickListener() { @Override public void onClick(DialogInterface dialog, int item, boolean isChecked) { // for now just show that the user touched an option Toast.makeText(_context, items[item], Toast.LENGTH_SHORT).show(); } }); builder.setPositiveButton("Okay", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int id) { // should I be examining what was checked here? dialog.dismiss(); } }); builder.setNegativeButton("Cancel", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int id) { dialog.cancel(); } }); AlertDialog alert = builder.create(); alert.show(); return true; }

  • iPhone UIView frame animation inconsistent why?

    - by Rick
    I have an app that uses an image loaded in from an UIImagePickerController instance. Once the picker is dismissed so as to reduce the jarring transition from the picker layout to the layout of the next function I initially have the UIImageView for the image fill the whole screen and then when the picker is dismissed the image 'squeezes' up to the top left of the screen. from the initWithFrame... targetPicView = [[UIImageView alloc] initWithFrame:CGRectMake(0.0, 0.0, 320.0, 480.0)]; [targetPicView setContentMode:UIViewContentModeScaleToFill]; this in a function called after dismissing the picker... [UIView beginAnimations:@"squeeze" context:context]; [UIView setAnimationCurve:UIViewAnimationCurveEaseInOut]; [UIView setAnimationDuration:0.75]; [targetPicView setFrame:CGRectMake(20.0, 20.0, 130.0, 150.0)]; [UIView commitAnimations]; The weird thing is that this works great when the image has been chosen from the library, the view shrinks down with the top left corner in place just as I planned but... If the image comes from the camera then the view shrinks with the top right corner in place instead and appears to come in from the left side of the screen. Can anyone shed any light on this?

  • Resizing video best practices (frame size)

    - by undefined
    I have read the following which is from Best Practices for Encoding Video with the VP6 Codec on the Adobe website here - http://www.adobe.com/devnet/flash/articles/encoding_video_print.html. It is talking about common video ratios (320x240, 640x480) Although these ratios are standard, and should be used to avoid distorting the video, the size of the encoded video is not set in stone. The original web video sizes used heights and widths that were evenly divisible by 16. This was mandatory for many early codecs. Although this is not necessary for modern codecs, you should stick to even heights and widths. What do they mean by 'even heights and widths'. I am thinking about encoding my video at 400x300 to make it slightly bigger, this is still 4x3 format but should I just stick at 320x240 and resize it on the screen? Clearly there are benefits to this in terms of storage size and delivery costs. In some places on my site I want to show the video at 400x300 but in others I want it to play full screen so this is why I am wondering if a larger original size (400x300) will give better results when blown up. Any thoughts?

  • plupload with webpy.

    - by markus
    Hi, i have a problem. I want to upload a file with plupload with the HML5 runtime. This is my html/js code : jQuery(function(){ jQuery("#uploader").pluploadQueue({ // General settings runtimes : 'html5', name : 'file', url : 'http://server.name/addContent', max_file_size : '${maxSize}$_("GB")', }); jQuery('#form_upload_file').submit(function(e) { var uploader = jQuery('#uploader').pluploadQueue(); // Validate number of uploaded files if (uploader.total.uploaded == 0) { // Files in queue upload them first if (uploader.files.length > 0) { // When all files are uploaded submit form uploader.bind('UploadProgress', function() { if (uploader.total.uploaded == uploader.files.length) jQuery('#form_upload_file').submit(); }); uploader.start(); } else alert('You must at least upload one file.'); e.preventDefault(); } }); }); <form id="form_upload_file" action="#" method="POST"> <div id="uploader"></div> <input type="hidden" name="token" value="token" /> <input type="hidden" name="idUser" value="$idUser" /> </form> So, when i click in the button to upload(the submit() method is not called), it does an OPTIONS HTTP request to my server so i don't know what i must do to save the file? this is my webpy code : def OPTIONS(self): web.header('Content-type', 'text/plain: charset=utf-8') web.header('Cache-Control', 'no-store, no-cache, must-revalidate') web.header('Cache-Control', 'post-check=0, pre-check=0', False) web.header('Pragma', 'no-cache') def POST(self): input = web.input(_unicode=False, file={})#on récupère les input self.copy(input.file.file) etc. any idea ? thanks.

  • UIButton's Custom image and frame

    - by Joo Park
    I have the following code. UIImage *cancelImg = [UIImage imageNamed:@"cancel.jpeg"]; UIButton *btnCancel = [UIButton buttonWithType:UIButtonTypeCustom]; btnCancel.userInteractionEnabled = YES; [btnCancel setFrame:CGRectMake(0.0,0.0, 28.0, 28.0)]; [btnCancel setImage:cancelImg forState:UIControlStateNormal]; cell.accessoryView = btnCancel; cancel.jpeg currently is bigger than 28 x 28 and it's actually 100 x 100. Why does the button display 100 x 100 size of the image when I've set the UIButton's size to 28 x 28?

  • HT create a new vector in data frame that takes correlation of existing vectors

    - by Milktrader
    I have a time series of two indexes, with each row representing the closing price on the same day. I'd like to go to row 30 and lookback over the last 30 'days' and calculate the pearson correlation. And then store that value in a new vector. Then, repeat the calculation for the entire time series. It is a trivial task in Excel, so I'm convinced it can be done in R. I don't know the method to use though.

  • Directly call distutils' or setuptools' setup() function with command name/options, without parsing

    - by Ryan B. Lynch
    I'd like to call Python's distutils' or setuptools' setup() function in a slightly unconventional way, but I'm not sure whether distutils is meant for this kind of usage. As an example, let's say I currently have a 'setup.py' file, which looks like this (lifted verbatim from the distutils docs--the setuptools usage is almost identical): from distutils.core import setup setup(name='Distutils', version='1.0', description='Python Distribution Utilities', author='Greg Ward', author_email='[email protected]', url='http://www.python.org/sigs/distutils-sig/', packages=['distutils', 'distutils.command'], ) Normally, to build just the .spec file for an RPM of this module, I could run python setup.py bdist_rpm --spec-only, which parses the command line and calls the 'bdist_rpm' code to handle the RPM-specific stuff. The .spec file ends up in './dist'. How can I change my setup() invocation so that it runs the 'bdist_rpm' command with the '--spec-only' option, WITHOUT parsing command-line parameters? Can I pass the command name and options as parameters to setup()? Or can I manually construct a command line, and pass that as a parameter, instead? NOTE: I already know that I could call the script in a separate process, with an actual command line, using os.system() or the subprocess module or something similar. I'm trying to avoid using any kind of external command invocations. I'm looking specifically for a solution that runs setup() in the current interpreter. For background, I'm converting some release-management shell scripts into a single Python program. One of the tasks is running 'setup.py' to generate a .spec file for further pre-release testing. Running 'setup.py' as an external command, with its own command line options, seems like an awkward method, and it complicates the rest of the program. I feel like there may be a more Pythonic way.

  • R counting the occurance of similar rows of data frame

    - by Matt
    I have data in the following format called DF (this is just a made up simplified sample): eval.num, eval.count, fitness, fitness.mean, green.h.0, green.v.0, offset.0 random 1 1 1500 1500 100 120 40 232342 2 2 1000 1250 100 120 40 11843 3 3 1250 1250 100 120 40 981340234 4 4 1000 1187.5 100 120 40 4363453 5 1 2000 2000 200 100 40 345902 6 1 3000 3000 150 90 10 943 7 1 2000 2000 90 90 100 9304358 8 2 1800 1900 90 90 100 284333 However, the eval.count column is incorrect and I need to fix it. It should report the number of rows with the same values for (green.h.0, green.v.0, and offset.0) by only looking at the previous rows. The example above uses the expected values, but assume they are incorrect. How can I add a new column (say "count") which will count all previous rows which have the same values of the specified variables? I have gotten help on a similar problem of just selecting all rows with the same values for specified columns, so I supposed I could just write a loop around that, but it seems inefficient to me.

  • Passing options in autospec with Cucumber in Ruby on Rails Development

    - by TK
    I always run autospec to run features and RSpec at the same time, but running all the features is often time-consuming on my local computer. I would run every feature before committing code. I would like to pass the argument in autospec command. autospec doesn't obviously doesn't accept the arguments directly. Here's the output of autospec -h: autotest [options] options: -h -help You're looking at it. -v Be verbose. Prints files that autotest doesn't know how to map to tests. -q Be more quiet. -f Fast start. Doesn't initially run tests at start. I do have a cucumber.yml in config directory. I also have rerun.txt in the Rails root directory. cucumber -h gives me a lot of information about arguments. How can I run autospec against features that are tagged as @wip? I think I can make use of config/cucumber.yml. There are profile definitions. I can run cucumber -p wip to run only @wip-tagged features, but I'd like to do this with autospec. I would appreciate any tips for working with many spec and feature files.

  • emacs windows, distribute the width through the frame

    - by Gauthier
    I used once a very nice emacs function that set all my windows (emacs windows, not frames) width evenly. If you open emacs and do C-x 3 twice in a row, you get three vertical windows. Then running the function I am looking for makes the width of these windows the same. I can't for the life of me find this function again. Wouldn't someone help me to: find the name of the function give me the keyboard shortcut if any tell me what I should have done to find the answer by myself Thanks!
