  • Toubleshooting mapkit performance

    - by brettr
    I'm plotting over 500 points on a map using mapkit. Zooming is a little jittery compared to the native google map app. I've discovered what is causing the slowness. I'm adding custom annotations so that I can later add different pin colors and buttons for detail views: - (MKAnnotationView *) mapView:(MKMapView *)mapView viewForAnnotation:(AddressNote *) annotation { MKPinAnnotationView *annView=[[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:@"currentlocation"]; annView.pinColor = MKPinAnnotationColorGreen; annView.animatesDrop=TRUE; annView.canShowCallout = YES; annView.calloutOffset = CGPointMake(-5, 5); return annView; } If I comment out the above code, everything works fine. Very smooth with zooming in/out. Should I be adding annotations differently to boost performance?

  • Looking for a .NET 3.5 / J2EE architecture concept comparison article/chart

    - by Edward Tanguay
    We are thinking about combining .NET technology with Java technology (WCF, JBoss/ESB, MOM, WPF, WF) and I need to have a high-level idea of what are the apples and oranges in the .NET 3.5 and Java worlds. Does anyone know of a good, clear article or better yet a simple chart which answers questions such as: WCF in the Java world is __ the equivalent of WPF in the Java world is _ the closes thing to JBoss in the .NET world is _ the JVM and CLR are essentially the same except for these differences: .... in the Java world you don't have the concept of WF/WCF/WPF, instead you have .... there is no "LINQ" in the Java world yet, but you can use ___ the closest you get to ADO.NET Data Services in the Java world is .... I'm not looking to debate this so I'm not looking for "fighting points", I just need a neutral what-is-what chart comparing the two worlds.

  • Silverlight Line Graph with Gradient

    - by gav
    I have a series of points which I will turn into a line on a graph. What I want is to give the area under the graph a gradient fill. It would look somewhat similar to a Bloomberg graph like this; My question really has three parts; First, how should I fill only the area under the graph? Second, how do I fill that with a gradient? Finally, if I have multiple lines on the same graph any area under more than one line should have a greyscale gradient fill, how would you set this up? My biggest problem is deciding on the data structures to use, I could use many multiple sided shapes (One for each line/ data series) and then tell the brush to draw; Transparent if it's not in any shape The colour of one series if it's in one shape (Alpha relative to height to give grad) Black if it's in multiple shapes (Alpha relative to height to give grad) Then I'd draw the shapes' boundaries in white afterwards. Thanks, Gav

  • How to uninstall Ruby from /usr/local?

    - by Shreyas Satish
    Everything was working fine , until we decided to upgrade ruby to 1.8.7 from 1.8.6, and thats when all hell broke loose. When we compiled Ruby 1.8.7 from source it got installed into /usr/local/bin and Ruby 1.8.6 stayed in /usr/bin. Currently, we've uninstalled ruby 1.8.6 and by some stroke we deleted the ruby 1.8.7 files from /usr/local. when we try "which ruby" it points to /usr/local. If anybody could help us out what we need to do get back on track , we would be very grateful.and also any idea how we can uninstall ruby from /usr/local. we tried yum remove ruby , which removed ruby from /usr/bin.Thanks and Cheers !

  • How to get nearby POIs

    - by balexandre
    I have a database with Points of Interest that all have an address. I want to know what is the method/name/call to get all nearby POIs from a given position. I understand that I need to convert all my addresses to LAT / LON coordinates at least, but my question is: for a given LAT / LONG how do I get from the database/array what POIs are nearby by distance, for example: You are here 0,0 nearest POIs in a 2km radius are: POI A (at 1.1 Km) POI C (at 1.3 Km) POI F (at 1.9 Km) I have no idea what should I look into to get what I want :-( Any help is greatly appreciated. Thank you

  • Dual slider control with custom skin

    - by Ryan French
    Hi All, I'm currently trying to create a page for users to select two points from a range, using a slide control. The first point in the range is when an alert will be sent to the user, the second point is a max limit. What I would like to do is have the bar colored green from the 0 point to the first slider point, then orange between the two sliders, and lastly red from the second slider up to the other end of the bar. Does anyone know of an easy was I can do this or of a slider control that can be skinned to do this?

  • Codeigniter Routes for filename with extension

    - by thehuby
    I am using codeigniter and its routes system successfully with some lovely regexp, however I have come unstuck on what should be an easy peasy thing in the system. I want to include a bunch of search engine related files (for Google webmaster etc.) plus the robots.txt file, all in a controller. So, I have create the controller and updated the routes file and don't seem to be able to get it working with these files. Here's a snip from my routes file: $route['robots\.txt|LiveSearchSiteAuth\.xml'] = 'search_controller/files'; Within the function I use the URI helper to figure out which content to show. Now I can't get this to match, which points to my regexp being wrong. I'm sure this is a really obvious one but its late and my caffeine tank is empty :)

  • Weaknesses of Hibernate

    - by Sinuhe
    I would like to know which are the weak points of Hibernate 3. This is not pretended to be a thread against Hibernate. I think it will be a very useful knowledge for decide if Hibernate is the best option for a project or for estimating its time. A weakness can be: A bug Where JDBC or PLSQL are better Performance issues ... Also, can be useful to know some solutions for that problems, better ORM or techniques, or it will be corrected in Hibernate 4. For example, AFAIK, Hibernate will have a very bad performance updating 10000 rows comparing to JDBC in this query: update A set state=3 where state=2

  • SQLite.Net Issue With BeginTransaction

    - by cam
    I'm trying to use System.Data.Sqlite library, and I'm following the documentation about optimizing inserts so I copied this code directly out of the documentation: using (SQLiteTransaction mytransaction = myconnection.BeginTransaction()) { using (SQLiteCommand mycommand = new SQLiteCommand(myconnection)) { SQLiteParameter myparam = new SQLiteParameter(); int n; mycommand.CommandText = "INSERT INTO [MyTable] ([MyId]) VALUES(?)"; mycommand.Parameters.Add(myparam); for (n = 0; n < 100000; n ++) { myparam.Value = n + 1; mycommand.ExecuteNonQuery(); } } mytransaction.Commit(); } Now, I initialize I connection right before that by using SqlConnection myconnection = new SqlConnection("Data Source=blah"); I have a Database named blah, with the correct tables and values. The problem is when I run this code, it says "Operation is not valid due to the current state of the object" I've tried changing the code around several times, and it still points to BeginTransaction. What gives?

  • Shipping Integration into a Rails App

    - by MikeH
    I'm working on integrating a shipping solution into a Rails ecommerce app. We're only going to use one shipping provider. So the question is: Fedex or UPS? I'm wondering what Rails developers think about the tech side of this question. What do you think about the APIs, ease of integration, focus on developer's needs between Fedex and UPS? I was leaning towards Fedex, but from looking at the developers resources sections of both sites, it seems that UPS might be more developer friendly. Also, I'm going to be using Shopify's active_shipping gem: http://github.com/Shopify/active_shipping And I also based my app off the Spree Ecommerce solution, but I don't think that's particularly relevant to the question. Spree wrote a wrapper to integrate active_shipping with the Spree system. I gave away all my points, so SO wont' let me post another link in this question. But if you google "Spree active-shipping", their wrapper on github is the first result. Thanks.

  • Get all window handles for a process

    - by Jeremy
    Using Microsoft Spy++, I can see that the following windows that belong to a process: Process XYZ window handles, displayed in tree form just like Spy++ gives me: A B C D E F G H I J K I can get the process, and the MainWindowHandle property points to the handle for window F. If I enumerate the child windows using I can get a list of window handles for G through K, but I can't figure out how to find the window handles for A through D. How can I enumerate windows that are not children of the handle specified by MainWindowHandle of the Process object? To enumerate I'm using the win32 call: [System.Runtime.InteropServices.DllImport(strUSER32DLL)] public static extern int EnumChildWindows(IntPtr hWnd, WindowCallBack pEnumWindowCallback, int iLParam);

  • Comparing images using SIFT

    - by Luís Fernando
    I'm trying to compare 2 images that are taken from a digital camera. Since there may be movement on the camera, I want to first make the pictures "match" and then compare (using some distant function). To match them, I'm thinking about cropping the second picture and using SIFT to find it inside the first picture... it will probably have a small difference on scale/translation/rotation so then I'd need to find the transformation matrix that converts image 1 to image 2 (based on points found by SIFT) any ideas on how to do that (or I guess that's a common problem that may have some opensource implementation?)? thanks

  • C# Drawing Oracle Spatial Geometries

    - by Keeper
    I need to create a simple app which can display geometries from Oracle Spatial in C#. These geometries are exported from AutoCAD Map 3D 2010 to Oracle Spatial. I need to pan, zoom, manage layers of these objects, events (like right click to popup a contextual menu, potentially different for every object), creating/deleting points (maybe also other polygons): a sort of simple AutoCAD interface. Should I look for an AutoCAD OEM license? Is there a drawing framework which can handle this or do I need to create my own?

  • GIS: Converting multi polygons to multiple features

    - by Kangkan
    Hi, I am involved in a GIS project. I have a base map file (shape file) that contains the road layer for a large portion of a town. The problem is that the shape file contains only two features each containing around 500000 points each. The features are multipolygons containing a large no of polygons inside. I wish to convert it to numerous features each containing not more than one polygon. Is it possible? If yes, how?

  • .ics Calendar File - Parsing Date Time - What is the time format?

    - by Josh
    I am coding in php, attempting to get the start\end dates and times for events. I am utilizing the following RegEx for parsing out the information: $pattern='/(?P<StartDate>[0-9]{8})T(?P<StartTime>[0-9]{6}) .+(?P<EndDate>[0-9]{8})T(?P<EndTime>[0-9]{6})/'; The sample event entry is here: BEGIN:VEVENT UID:34b09fd7-8e6e-4d56-86b0-445745b89d93 ORGANIZER;CN=*********:mailto:********* DTSTART;TZID="(GMT-06.00) Central Time (US & Canada)":20100413T130000 DTEND;TZID="(GMT-06.00) Central Time (US & Canada)":20100413T160000 STATUS:CONFIRMED CLASS:PRIVATE X-MICROSOFT-CDO-INTENDEDSTATUS:BUSY TRANSP:OPAQUE X-MICROSOFT-DISALLOW-COUNTER:TRUE DTSTAMP:20100414T140711Z SEQUENCE:0 END:VEVENT 20100413T130000 and 20100413T160000 are the start and end points. The dates are straight forward, however how do I interpret the time part? This event starts at one and ends at four.

  • Why aren't these shared_ptrs pointing to the same container?

    - by BeeBand
    I have a class Model: class Model { ... boost::shared_ptr<Deck> _deck; boost::shared_ptr<CardStack> _stack[22]; }; Deck inherits from CardStack. I tried to make _stack[0] point to the same thing that _deck points to by going: { _deck = boost::shared_ptr<Deck>(new Deck()); _stack[0] = _deck; } It seems that the assignment to _deck of _stack[0] results in a copy of _deck being made. How can I get them to point to the same thing?

  • Cannot Debug Unmanaged Dll from C#

    - by JustSmith
    I have a DLL that was written in C++ and called from a C# application. The DLL is unmanaged code. If I copy the DLL and its .pdb files with a post build event to the C# app's debug execution dir I still can't hit any break points I put into the DLL code. The break point has a message attached to it saying that "no symbols have been loaded for this document". What else do I have to do to get the debugging in the dll source? I have "Tools-Options-Debugging-General-Enable only my code" Disabled. The DLL is being compiled with "Runtime tracking and disable optimizations (/ASSEMBLYDEBUG)" and Generate Debug Info to "Yes (/DEBUG)"

  • Django: tinyMCE and cross site javascript

    - by pistacchio
    Hi, follow this question, I was able to set some textareas in my admin page as richtext inputs. The most voted answer suggests to follow an example and is what i did. Also, it talks about a problem concerning "blank pages". I'm having the same problem and I'm not able to solve it. I have my media files served by a different server, so MEDIA_URL points to a different host with a different port. To simulate this in my dev environment, I also serve media files from a different port. Debugging the failing javascript, Chrome yelds: Unsafe JavaScript attempt to access frame with URL http://localhost:8000/admin/blog/post/add/ from frame with URL http://localhost:88/s3mangerie/js/tiny_mce/themes/advanced/image.htm. Domains, protocols and ports must match. How to solve this problem? Thanks

  • Calculating co-ordinate of a point on a path given a distance

    - by Alex
    I'm working on a project that surveys the condition of a road or highway using a calibrated trip computer connected to a rugged-PC. An operator keys in defect codes as they travel along a pre-defined route. I need to show an indicator on the map screen that shows the vehicles current position, taking into account the distance data from the trip computer. I know the exact lat lon co-ordinates at the starting point of each section of road, and the road is made up of a series of points. The question is: how can I calculate the lat lon co-ordinates of the vehicle assuming that it has continued on the route and traveled a certain distance (e.g. 1.4km). The co-ordinates would be 'locked onto' the road line, as shown in blue on the diagram below. Thanks, Alex

  • How can I get mounted name and (Drive letter too) on Windows using python

    - by aberry
    I am using Daemon tool to mount an ISO image on Windows XP machine.I do mount using Daemon command (daemon.exe -mount 0,). Above command will mount ISO image to device number. In my case I have 4 partition (C,D,E,F) and G for DVD/CD-RW. Now what happen, ISO gets mounted to drive letter 'H:' with name (as defined while creating ISO) say 'testmount' My queries:- 1) How can I get mount name of mounted ISO image (i.e. 'testmount'). Just another case; if there are already some mount points existing on machine and I created a new one using Daemon tool. Then If I can get latest one using script that will be great. 2) How to get drive letter where it did get mounted. If anyone know python script or command (or even Win command ) to get these info. do let me know. Thanks...

  • Silverlight Navigation - how to override Back button behavior

    - by Stephen Ellis
    I'm trying to override the default behavior of the browser's back button in Silverlight (v4). Each of my XAML pages has an ability to show options. I want these options to be hidden when the user presses the back button, or to move to the previous page if the options are not visible. The Silverlight Frame seems to set back and forward points whenever the user navigates to a page with a new QueryString. Is there any other way of implementing my scenario other than having to implement a querystring component for my ShowOptions property?

  • Does anyone know a better alternative to MS Excel's Solver?

    - by tundal45
    My company has to crunch a lot of data and part of the process involves running the solver and plotting a graph through resulting data points. Obviously there is a lot of copy and paste involved and the whole process is shaky, error prone and all round cluster-fudge. I was wondering if there was an alternative to the solver that can be used so that even if we have to use excel to plot the final graph, there will be a lot less data that needs to be copied and pasted back and forth. It would be great especially if the tool could be easily integrated into a .NET application but I am open to suggestions that may require a little bit of code-fu to get this to work. Thanks!

  • iPhone Live Video Stream Media Player

    - by happyhammer83
    I'm hoping to make an app that streams live video that has a view placed on top with labels and a button on it. From my research and testing of the http video streaming feature (available since iPhone 3.0 OS), it seems that you create a webview that points to the index html that contains the converted video stream, and this displays as a quicktime video in the app. This means that I don't have control over the Media Player that is opened. Does anyone know how you can control this? I know that the Apple's MoviePlayer sample code shows you how to place views on top of a MediaPlayer video, but how can this be done with a http live stream? Thanks in advance.

  • Draw a textured triangle (patch) in Matlab

    - by Petter
    I have a triangle in (u,v) coordinates in an image. I would like to draw this triangle at 3D coordinates (X,Y,Z) texture-mapped with the triangle in the image. Here, u,v,X,Y,Z are all vectors with three elements representing the three corners of the triangle. I have a very ugly, slow and insatisfactory solution in which I (1) extract a rectangular part of the image, (2) transform it to 3D space with the transformation defined by the three points, (3) draw it with surface, and (4) finally masking out everything that is not part of the triangle with AlphaData. Surely there must be an easier way of doing this?

  • Pocket IE onmousedown onmousemove onmouseup ?

    - by eidylon
    Hello all, I have a control which I wrote for capturing signatures on a web page, by using onmousedown, onmousemove and onmouseup on a div to track the mouse, and capture points comprising a signature. Now we need this to work on Windows Mobile 6.5 powered devices... but it seems that the div element does not support the mouse events in Pocket IE, which would seem to be supported by this blog. But according to MSDN, the WinCE (which WinMo/PPC is based off of) version of IE does support these mouse events for some unknown list of elements. So can anyone tell me, are there any elements: img, a, span or whatever that support onmouse[down|move|up] in WinMo 6.5 Pocket IE? Thanks! If not, anyone have any other ideas for capturing a signature on a web page in Pocket IE?
