  • How to iterate on boost::mutable_queue

    - by Tristram Gräbener
    Hello, I need a priority queue where I can increase or decrease the priority key. So boost::mutable_queue seemed perfect despite the lack of documentation. The problem is that I need to iterate at some point over all the elements in the queue. How can I do that? Or is there an othe data structure that would work (preferably in boost)?

  • why copy and paste codes is dangerous

    - by Yigang Wu
    sometimes, my boss will complain us why we need so long time to implement a feature, actually, the feature has been implemented in other AP before, you just need to copy and paste codes from there. The cost should be low. It's really a hard question, because copy and paste codes is not a easy thing from my point. Do you have any good reason to explain your boss who doesn't know technology?

  • CSS Print Style Sheets - Examples

    - by bsreekanth
    Trying to learn about how to effectively use print.css, so that graphical and navigational elements are not shown in print preview/print. Read some articles, and part of print css of html5 boilerplate. Two sites, which was quite impressive the way they change the look during print are http://css-tricks.com/ http://bottlerocketcreative.com/ But I cannot see the css related to print. Can you please point to the css they use to learn how to do similar transformation. thanks.

  • Visual studio 2010 colourizers, intellisense and the rest. Where to start!!

    - by Owen
    Ok, before I begin I realize that there is a lot of documentation on this subject but I have thus far failed to get even basic colourization working for VS2010. My goal is to simply get to a point where I can open a document and everything is coloured red, from here I can implement the relevant parsing logic. Here's what I have tried/found: 1) Downloaded all the relevent SDK's and such- Found the ook sample (http://code.msdn.microsoft.com/ookLanguage) - didn't build, didn't work. 2) Knowing almost nothing about MEF read through "Implementing a Language Service By Using the Managed Package Framework" - http://msdn.microsoft.com/en-us/library/bb166533(v=VS.100).aspx This was pretty much a copy and paste of all the basic stuff here, and also updating some references which were out of date with the sample see: http://social.msdn.microsoft.com/Forums/en-US/vsx/thread/a310fe67-afd2-4592-b295-3fc86fec7996 Now, I have got to a point where when running the package MEF appears to have hooked up correctly (I know this because with the debugger open I can see that the packages initialize and FDoIdle methods are being hit). When I open a file of the extension I have registered with the ProvideLanguageExtensionAttribute everything dies as if in an endless loop, yet no debug symbols hit (though they are loaded). Looking at the ook sample and the MEF examples they seem to be totally different approaches to the same problem. In the ook sample there are notions of Clasifications and Completion controllers which aren't mentioned in the MEF example. Also, they don't seem to create a Package or Language service, so I have no idea how it should work? With the MEF example, my assumption is that I need to hook into the "IScanner.ScanTokenAndProvideInfoAboutIt" to provide syntax highlighting? Which would be fine if I could ever hit this method. So my first question I guess is which approach should I be taking here? Or do they both somehow tie together? My second questions is, where can I find a basic fully working project that implements bog standard basic syntax highlighting and intellisense or VS2010? Thirdly, in the MEF example when I created a Package there were a bunch of test projects created for me. I appears that the integration tests launch the VS2010 test rig somehow, but the test fails. It would be good to write my service with tests but I have no idea what/how I can test each interaction so any references to testing Language services would be helpful. Finally, please throw any resource/book links my way that I may find useful. Cheers, Chris. N.B. Sorry I realize this is part question part rant, but I have never been so confused.

  • C++ strcpy(Struct.Property, "VALUE") Use in C#?

    - by gtas
    Hi all, i created a Wrapper for a C++ dll. While reading the documentation i reached to a point using this function strcpy(StructName.strPropGetter, "A STRING"); I'm not kinda C++ guy, i can't figure how to transfer this code in C#. My wrapper gave me this property without a setter. Any light would be nice. Thank you

  • What is the proper way to wrap this php loop around the javascript

    - by zac
    Hi, I am mashing together the Google Maps 2 script with a Wordpress loop so there is a CMS platform for the map data. I have this working fine : var point = new GLatLng(48.5139,-123.150531); var marker = createMarker(point,"Lime Kiln State Park", '<?php $post_id = 182; $my_post = get_post($post_id); $mapTitle = $my_post->post_title; $mapIMG = get_post_meta($post_id, 'mapImage', true); $snip = get_post_meta($post_id, 'mapExcerpt', true); echo "<div class=\"span-12\">"; echo "<div class=\"mapTitle\">"; echo $mapTitle; echo "</div>"; echo "<img class=\"mapImage\" src=\""; echo bloginfo('url'); echo "/wp-content/files_mf/"; echo $mapIMG; echo "\" /> "; echo "<div class=\"mapContent\">"; echo $snip; echo "</div>"; echo "<div class=\"moreLink\">"; echo "<a href=\""; echo $permalink = get_permalink( $post_id ); echo "\">Find out more &raquo; </a>"; echo "</div>"; echo "</div>"; ?>') map.addOverlay(marker); However I am hoping to also be able to include the two variables at the start within the php loop so that both of those can also be generated by custom fields. Can someone please show me that the proper way to write this would be so that all of the data can be pulled in from fields within that post id? So the lat/long and title could also be set from within the post 182 fields.

  • How can I link axes of imshow plots for zooming and panning?

    - by Adam Fraser
    Suppose I have a figure canvas with 3 plots... 2 are images of the same dimensions plotted with imshow, and the other is some other kind of subplot. I'd like to be able to link the x and y axes of the imshow plots so that when I zoom in one (using the zoom tool provided by the NavigationToolbar), the other zooms to the same coordinates, and when I pan in one, the other pans as well. Subplot methods such as scatter and histogram can be passed kwargs specifying an axes for sharex and sharey, but imshow has no such configuration. I started hacking my way around this by subclassing NavigationToolbar2WxAgg (shown below)... but there are several problems here. 1) This will link the axes of all plots in a canvas since all I've done is get rid of the checks for a.in_axes() 2) This worked well for panning, but zooming caused all subplots to zoom from the same global point, rather than from the same point in each of their respective axes. Can anyone suggest a workaround? Much thanks! -Adam from matplotlib.backends.backend_wxagg import NavigationToolbar2WxAgg class MyNavToolbar(NavigationToolbar2WxAgg): def __init__(self, canvas, cpfig): NavigationToolbar2WxAgg.__init__(self, canvas) # overrided # As mentioned in the code below, the only difference here from overridden # method is that this one doesn't check a.in_axes(event) when deciding which # axes to start the pan in... def press_pan(self, event): 'the press mouse button in pan/zoom mode callback' if event.button == 1: self._button_pressed=1 elif event.button == 3: self._button_pressed=3 else: self._button_pressed=None return x, y = event.x, event.y # push the current view to define home if stack is empty if self._views.empty(): self.push_current() self._xypress=[] for i, a in enumerate(self.canvas.figure.get_axes()): # only difference from overridden method is that this one doesn't # check a.in_axes(event) if x is not None and y is not None and a.get_navigate(): a.start_pan(x, y, event.button) self._xypress.append((a, i)) self.canvas.mpl_disconnect(self._idDrag) self._idDrag=self.canvas.mpl_connect('motion_notify_event', self.drag_pan) # overrided def press_zoom(self, event): 'the press mouse button in zoom to rect mode callback' if event.button == 1: self._button_pressed=1 elif event.button == 3: self._button_pressed=3 else: self._button_pressed=None return x, y = event.x, event.y # push the current view to define home if stack is empty if self._views.empty(): self.push_current() self._xypress=[] for i, a in enumerate(self.canvas.figure.get_axes()): # only difference from overridden method is that this one doesn't # check a.in_axes(event) if x is not None and y is not None and a.get_navigate() and a.can_zoom(): self._xypress.append(( x, y, a, i, a.viewLim.frozen(), a.transData.frozen())) self.press(event)

  • Google Map + MarkerClusterer only takes place when map completely zooms out

    - by user415795
    The clustering works but somehow it only takes place at the maximum zoom out(the largest view with all nations), the moment I zoom in by 1 value, the clustering icon changes back to markers. I try with all kinds of values on the maxZoom and gridSize clusterer options with no help. Can someone please kindly advice. Thanks. <script language="javascript" type="text/javascript"> var markersArray = []; var mc = null; var markersArray = []; var mc = null; var map; var mapOptions; var geocoder; var infoWindow; var http_request = false; var lat = 0; var lng = 0; var startingZoom = 7; var lowestZoom = 1; // The lower the number, the more places can be seen on within the bounds. var highestZoom = 8; function mapLoad() { geocoder = new google.maps.Geocoder(); infoWindow = new google.maps.InfoWindow(); mapOptions = { zoomControl: true, zoom: 2, minZoom: lowestZoom, maxzoom: highestZoom, draggable: true, scrollwheel: true, disableDoubleClickZoom: true, mapTypeId: google.maps.MapTypeId.ROADMAP }; map = new google.maps.Map(document.getElementById('map'), mapOptions); } $(document).ready(function () { var searchUrl; var locations; // Place the user's current location marker on the map var Location = new google.maps.LatLng(1.340319, 103.743744); var Location2 = new google.maps.LatLng(1.322347, 103.757881); createMarker('1', Location, 'My Location', '', '', '', '/Images/home.png'); createMarker('1', Location2, 'My Location', '', '', '', '/Images/bb.png'); var bounds = new google.maps.LatLngBounds(); bounds.extend(gameLocation); map.fitBounds(bounds); }); // Create the marker with address information function createMarker(actId, point, address1, address2, town, postcode, icon) { var marker = new google.maps.Marker({ map: map, icon: icon, position: point, title: address1, animation: google.maps.Animation.DROP }); marker.metadata = { id: actId }; markersArray.push(marker); mc = new MarkerClusterer(map, markersArray); return marker; } </script>

  • How to detect working internet connection in C#?

    - by detariael
    I have a C# code that basically uploads a file via FTP protocol (using FtpWebRequest). I'd like, however, to first determine whether there is a working internet connection before trying to upload the file (since, if there isn't there is no point in trying, the software should just sleep for a time and check again). Is there an easy way to do it or should I just try to upload the file and in case it failed just try again, assuming the network connection was down?

  • Setting a ListView Divider in code

    - by deSelby
    One of my ListView's needs to be created in code. When I specify a ListView in xml, I can set a dividerHeight and assign a color to the divider. But apparently, in code a color is not acceptable nor is pointing to a resource id. Only a Drawable is acceptable - and I haven't gotten to that chapter yet. Can someone point me to an example of setting a ListView divider in code?

  • Centering fonts in VB6

    - by James Musser
    How do you determine the length of a string of text in Arial Bold font, and then center it in VB6? If not here, can you point me in a direction where I might be able to find this information? We're not using a "label" or "picture box" do print the text to the screen. We are sizing the text on the fly, and allowing the user to scale the size of our application to their liking. We write the text to screen using code.

  • Developers portfolios

    - by Alex
    I'm wondering if you have one, or u know any developer/programmer online portofolio. I know many web developers have one (and in many cases very well designed), but not any C++ developer (for example). On the net there are only some good blogs about some programming language, but in many cases these are extremely poor from a design point of view and i'd say very "nerdy".

  • Is an editable select box the right way?

    - by Neil Middleton
    I have a scenario where a user is emailing another user in an HTML based web app. For the To: field, the user may select one of a pre-defined list of emails OR enter their own ignoring the pre-defined options. What would be the best way of doing this from a UI point of view? I've looked at editable select boxes using jQuery but none seem to let you enter your own option. Is there some other UI mechanism that would work here?
