  • IE6 and fieldset background color?

    - by codemonkey613
    Hey, I'm having some difficulty with CSS and IE6 compatibility. URL: http://bit.ly/dlX7cS Problem #1: I put a background image on the fieldset around Canada and United States. In IE6 and IE7, the background bleeds above the border-top of the fieldset. So, I found a fix. It is applied only to IE browsers, and moves the legend up a few pixels, aligning the background correctly. <!-- Fix: IE6/IE7, Legends --> <!--[if lte IE 7]> <style type="text/css"> fieldset { position: relative; } fieldset legend { position: absolute; top: -0.5em; left: 0; } </style> <![endif]--> This fixes IE7. But in IE6, it seems to make my legend for Canada vanish completely. Does anyone have a copy of IE6 they can open my site and tell me if you see Canada label. (I am testing with a multi-IE program, and it keeps crashing. My copy might not be accurate). If it's not there, any suggestions on how to fix it? Also, any suggestion on where I can download working copy of IE6? Problem #2: I have a Google Map embedded using iframe. The width of that iframe is 515px. In Firefox, Chrome, IE7 -- that is the correct alignment. But in IE6, it gets <br/> underneath the Just Energy paragraph beside it. It doesn't fit. I have to change width to 513px for it to fit. Uhm, anyone know where those 2px of difference happen? I removed border, padding, margin from the iframe, but still something is happening. <!-- Google Maps --> <iframe class="gmap" src="http://maps.google.com/maps/ms?hl=en&amp;ie=UTF8&amp;msa=0&amp;msid=100146512697135839835.000481e2a2779e8865863&amp;ll=42,-100&amp;spn=20,80&amp;output=embed" frameborder="0" marginheight="0" marginwidth="0" scrolling="no"></iframe> <!-- / Google Maps --> Er, big headache. lol

  • Python: How to read huge text file into memory

    - by asmaier
    I'm using Python 2.6 on a Mac Mini with 1GB RAM. I want to read in a huge text file $ ls -l links.csv; file links.csv; tail links.csv -rw-r--r-- 1 user user 469904280 30 Nov 22:42 links.csv links.csv: ASCII text, with CRLF line terminators 4757187,59883 4757187,99822 4757187,66546 4757187,638452 4757187,4627959 4757187,312826 4757187,6143 4757187,6141 4757187,3081726 4757187,58197 So each line in the file consists of a tuple of two comma separated integer values. I want to read in the whole file and sort it according to the second column. I know, that I could do the sorting without reading the whole file into memory. But I thought for a file of 500MB I should still be able to do it in memory since I have 1GB available. However when I try to read in the file, Python seems to allocate a lot more memory than is needed by the file on disk. So even with 1GB of RAM I'm not able to read in the 500MB file into memory. My Python code for reading the file and printing some information about the memory consumption is: #!/usr/bin/python # -*- coding: utf-8 -*- import sys infile=open("links.csv", "r") edges=[] count=0 #count the total number of lines in the file for line in infile: count=count+1 total=count print "Total number of lines: ",total infile.seek(0) count=0 for line in infile: edge=tuple(map(int,line.strip().split(","))) edges.append(edge) count=count+1 # for every million lines print memory consumption if count%1000000==0: print "Position: ", edge print "Read ",float(count)/float(total)*100,"%." mem=sys.getsizeof(edges) for edge in edges: mem=mem+sys.getsizeof(edge) for node in edge: mem=mem+sys.getsizeof(node) print "Memory (Bytes): ", mem The output I got was: Total number of lines: 30609720 Position: (9745, 2994) Read 3.26693612356 %. Memory (Bytes): 64348736 Position: (38857, 103574) Read 6.53387224712 %. Memory (Bytes): 128816320 Position: (83609, 63498) Read 9.80080837067 %. Memory (Bytes): 192553000 Position: (139692, 1078610) Read 13.0677444942 %. Memory (Bytes): 257873392 Position: (205067, 153705) Read 16.3346806178 %. Memory (Bytes): 320107588 Position: (283371, 253064) Read 19.6016167413 %. Memory (Bytes): 385448716 Position: (354601, 377328) Read 22.8685528649 %. Memory (Bytes): 448629828 Position: (441109, 3024112) Read 26.1354889885 %. Memory (Bytes): 512208580 Already after reading only 25% of the 500MB file, Python consumes 500MB. So it seem that storing the content of the file as a list of tuples of ints is not very memory efficient. Is there a better way to do it, so that I can read in my 500MB file into my 1GB of memory?

  • getting database connectivity issue from only one part of my ASP.net project?

    - by Greg
    Hi, Something weird has started happening to my project with Dynamic Data. Suddenly I am now getting connection errors when going to the DD navigation pages, but things work fine on the default DD main page, and also other MVC pages I've added in myself work fine to the database.

  • Eclipselink factory.createEntityManager() stalls with more than one instance running

    - by Raven
    Hi, with my RCP program I have the problem that I want to have more than one copy running on my PC. The first instance runs very good. If I start the second instance, everything is fine until I want to access the database. Using this code: .. Map properties = new HashMap(); properties.put("javax.persistence.jdbc.driver", dbDriver); properties.put("javax.persistence.jdbc.url", dbUrl); properties.put("javax.persistence.jdbc.user", dbUser); properties.put("javax.persistence.jdbc.password", dbPass); try { factory = Persistence.createEntityManagerFactory( PERSISTENCE_UNIT_NAME, properties); } catch (Exception e) { System.out.println(e); } em=factory.createEntityManager(); // the second instance stops here ... with an persistence.xml of <?xml version="1.0" encoding="UTF-8"?> <persistence version="1.0" xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd"> <persistence-unit name="default"> <provider>org.eclipse.persistence.jpa.PersistenceProvider</provider> <class>myclasshere</class> <properties> <property name="eclipselink.ddl-generation" value="create-tables" /> <property name="eclipselink.ddl-generation.output-mode" value="database" /> <property name="eclipselink.jdbc.read-connections.min" value="1" /> <property name="eclipselink.jdbc.write-connections.min" value="1" /> <property name="eclipselink.jdbc.batch-writing" value="JDBC" /> <property name="eclipselink.logging.level" value="SEVERE" /> <property name="eclipselink.logging.timestamp" value="false" /> <property name="eclipselink.logging.session" value="false" /> <property name="eclipselink.logging.thread" value="false" /> </properties> </persistence-unit> </persistence> The program stalls / does not continue in the second instance beyond this step: em=factory.createEntityManager(); Debugging the program step by step showed me, that nothing happens at this point. Perhaps the program runs into a timeout. I havent been wainting for more than 1 minute.... Do you have any clues what might cause this stall might?

  • How to load entities into private collections using the entity framework

    - by Anton P
    I have a POCO domain model which is wired up to the entity framework using the new ObjectContext class. public class Product { private ICollection<Photo> _photos; public Product() { _photos = new Collection<Photo>(); } public int Id { get; set; } public string Name { get; set; } public virtual IEnumerable<Photo> Photos { get { return _photos; } } public void AddPhoto(Photo photo) { //Some biz logic //... _photos.Add(photo); } } In the above example i have set the Photos collection type to IEnumerable as this will make it read only. The only way to add/remove photos is through the public methods. The problem with this is that the Entity Framework cannot load the Photo entities into the IEnumerable collection as it's not of type ICollection. By changing the type to ICollection will allow callers to call the Add mentod on the collection itself which is not good. What are my options? Edit: I could refactor the code so it does not expose a public property for Photos: public class Product { public Product() { Photos = new Collection<Photo>(); } public int Id { get; set; } public string Name { get; set; } private Collection<Photo> Photos {get; set; } public IEnumerable<Photo> GetPhotos() { return Photos; } public void AddPhoto(Photo photo) { //Some biz logic //... Photos.Add(photo); } } And use the GetPhotos() to return the collection. The other problem with the approach is that I will loose the change tracking abilities as I cannot mark the collection as Virtual - It is not possible to mark a property as private virtual. In NHibernate I believe it's possible to map the proxy class to the private collection via configuration. I hope that this will become a feature of EF4. Currently i don't like the inability to have any control over the collection!

  • Delphi native Web Service applications not working. IIS 7 seems to be stripping the pathinfo

    - by Cary Jensen
    I've run into an interesting problem that I never encountered with XP or IIS 6. Basically, I can't get a native Delphi (WebBroker) Web service server to work with a native Web service client in Windows 7 64-bit. Here's the most basic breakdown. If I create a new Web service application in Delphi 2010 (or any version, back to Delphi 7), and access it using IE 8, I can see the HTML that the WSDLHTMLPublish component creates, but I can never get to the SOAP. In the same way, the WSDL Importer cannot get to the SOAP either. (I have IIS 7 configured to use a 32-bit application pool, and I have created a working Script Map to the Handler Mappings. In short, the 32-bit ISAPI Web service is running). For example, I have a simple Web service server named TestService (created using the default sample interface generated when you create a new Web service server). I installed it in a virtual directory named scripts. If I enter http://localhost/scripts/TestService.dll/wsdl, IIS 7 displays the page http://localhost/scripts/TestService.dll. If I put my mouse over the WSDL link for the ITestService, I see http://localhost/scripts/TestService.dll/wsdl/ITestService in the status bar. However, when I click this link, the address bar shows http://localhost/scripts/TestService.dll/wsdl/ITestService, but I see only the HTML from http://localhost/scripts/TestService.dll. There seems no way to get to the SOAP definition. IIS 7 seems to be ignoring everything after the script name (it is ignoring the pathinfo). Additional evidence that IIS7 is stripping off the pathinfo is that if I pause my mouse over the ITestService link, the statusbar shows http://localhost/scripts/TestService.dll?intf=ITestService. Clicking that link takes me to another HTML page, the one associated with http://localhost/scripts/TestService.dll?intf=ITestService. However, any link that includes a pathinfo following the script name, takes me simply to http://localhost/scripts/TestService.dll. I have tested this in Delphi 7, Delphi 2010, and Delphi XE, with the same results. I am guessing that IIS7 is stripping off the pathinfo, since even the WSDL Importer cannot get to the SOAP definition. Tried creating a new Web service using the CGI option, and got the same result. Have any idea what is going on? Added: Bob Swart reports he has had no problems under Windows 7 32-bit. Downloading the 32-bit OS and will try that (in a new VM).

  • Using ASP.NET MVC, Linq To SQL, and StructureMap causing DataContext to cache data

    - by Dragn1821
    I'll start by telling my project setup: ASP.NET MVC 1.0 StructureMap 2.6.1 VB I've created a bootstrapper class shown here: Imports StructureMap Imports DCS.Data Imports DCS.Services Public Class BootStrapper Public Shared Sub ConfigureStructureMap() ObjectFactory.Initialize(AddressOf StructureMapRegistry) End Sub Private Shared Sub StructureMapRegistry(ByVal x As IInitializationExpression) x.AddRegistry(New MainRegistry()) x.AddRegistry(New DataRegistry()) x.AddRegistry(New ServiceRegistry()) x.Scan(AddressOf StructureMapScanner) End Sub Private Shared Sub StructureMapScanner(ByVal scanner As StructureMap.Graph.IAssemblyScanner) scanner.Assembly("DCS") scanner.Assembly("DCS.Data") scanner.Assembly("DCS.Services") scanner.WithDefaultConventions() End Sub End Class I've created a controller factory shown here: Imports System.Web.Mvc Imports StructureMap Public Class StructureMapControllerFactory Inherits DefaultControllerFactory Protected Overrides Function GetControllerInstance(ByVal controllerType As System.Type) As System.Web.Mvc.IController Return ObjectFactory.GetInstance(controllerType) End Function End Class I've modified the Global.asax.vb as shown here: ... Sub Application_Start() RegisterRoutes(RouteTable.Routes) 'StructureMap BootStrapper.ConfigureStructureMap() ControllerBuilder.Current.SetControllerFactory(New StructureMapControllerFactory()) End Sub ... I've added a Structure Map registry file to each of my three projects: DCS, DCS.Data, and DCS.Services. Here is the DCS.Data registry: Imports StructureMap.Configuration.DSL Public Class DataRegistry Inherits Registry Public Sub New() 'Data Connections. [For](Of DCSDataContext)() _ .HybridHttpOrThreadLocalScoped _ .Use(New DCSDataContext()) 'Repositories. [For](Of IShiftRepository)() _ .Use(Of ShiftRepository)() [For](Of IMachineRepository)() _ .Use(Of MachineRepository)() [For](Of IShiftSummaryRepository)() _ .Use(Of ShiftSummaryRepository)() [For](Of IOperatorRepository)() _ .Use(Of OperatorRepository)() [For](Of IShiftSummaryJobRepository)() _ .Use(Of ShiftSummaryJobRepository)() End Sub End Class Everything works great as far as loading the dependecies, but I'm having problems with the DCSDataContext class that was genereated by Linq2SQL Classes. I have a form that posts to a details page (/Summary/Details), which loads in some data from SQL. I then have a button that opens a dialog box in JQuery, which populates the dialog from a request to (/Operator/Modify). On the dialog box, the form has a combo box and an OK button that lets the user change the operator's name. Upon clicking OK, the form is posted to (/Operator/Modify) and sent through the service and repository layers of my program and updates the record in the database. Then, the RedirectToAction is called to send the user back to the details page (/Summary/Details) where there is a call to pull the data from SQL again, updating the details view. Everything works great, except the details view does not show the new operator that was selected. I can step through the code and see the DCSDataContext class being accessed to update the operator (which does actually change the database record), but when the DCSDataContext is accessed to reload the details objects, it pulls in the old value. I'm guessing that StructureMap is causing not only the DCSDataContext class but also the data to be cached? I have also tried adding the following to the Global.asax, but it just ends up crashing the program telling me the DCSDataContext has been disposed... Private Sub MvcApplication_EndRequest(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.EndRequest StructureMap.ObjectFactory.ReleaseAndDisposeAllHttpScopedObjects() End Sub Can someone please help?

  • Tiling rectangles seamlessly in WPF

    - by Joe White
    I want to seamlessly tile a bunch of different-colored Rectangles in WPF. That is, I want to put a bunch of rectangles edge-to-edge, and not have gaps between them. If everything is aligned to pixels, this works fine. But I also want to support arbitrary zoom, and ideally, I don't want to use SnapsToDevicePixels (because it would compromise quality when the image is zoomed way out). But that means my Rectangles sometimes render with gaps. For example: <Page xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Background="Black"> <Canvas SnapsToDevicePixels="False"> <Canvas.RenderTransform> <ScaleTransform ScaleX="0.5" ScaleY="0.5"/> </Canvas.RenderTransform> <Rectangle Canvas.Left="25" Width="100" Height="100" Fill="#CFC"/> <Rectangle Canvas.Left="125" Width="100" Height="100" Fill="#CCF"/> </Canvas> </Page> If the ScaleTransform's ScaleX is 1, then the Rectangles fit together seamlessly. When it's 0.5, there's a dark gray streak between them. I understand why -- the combined semi-transparent edge pixels don't combine to be 100% opaque. But I would like a way to fix it. I could always just make the Rectangles overlap, but I won't always know in advance what patterns they'll be in (this is for a game that will eventually support a map editor). Besides, this would cause artifacts around the overlap area when things were zoomed way in (unless I did bevel-cut angles on the underlapping portion, which is an awful lot of work, and still causes problems at corners). Is there some way I can combine these Rectangles into a single combined "shape" that does render without internal gaps? I've played around with GeometryDrawing, which does exactly that, but then I don't see a way to paint each RectangleGeometry with a different-colored brush. Are there any other ways to get shapes to tile seamlessly under an arbitrary transform, without resorting to SnapsToDevicePixels?

  • C# or C++ game: many 16 color images loaded into RAM. Efficient solution?

    - by user560639
    I am in the planning stages of creating a fighting game and am unsure how to handle one issue relating to memory. Background info: - Still debating whether to use C# (XNA) or C++. We do not want to commit to either until we have explored how to solve this problem in both languages. - Using a max of 256MB RAM would be great if possible. - Two characters will be present at a time, and these characters can only change between battles. There is time to load/free memory between battles, but the game needs to run at a constant 60 drawn frames per second during combat. Each frame is 16.67ms - The total number of images per character is in the low hundreds. Each image is roughly 200x400 pixels. Only one image from each character will be displayed at any given moment. Uncompressed, each image takes roughly 300kb from my calculations; upwards of 100MB for a whole character. This is pushing too close to the 256MB limit given that memory will be needed for some other resources as well. Since each image can be made with a total of 16 colors. Theoretically I should be able to use 1/8th the space if I can take advantage of this. I've looked around but haven't found any word of native support for paletted images. (Storing each pixel using fewer bits that each map to a 32-bit RGBa color) I was considering making my own file format with 4 bits per pixel (and some extra palette info), loading all the images of this new format into RAM before battle, and then when drawing any specific image, decompress only that image into a raw image so it can be rendered properly. I don't know if it's realistic to perform so many assignment operations (appx 200x400 for each character = 160k) each frame. It sounds very hacky to me. Does anyone have advice on whether my solution sounds reasonable, and if there is perhaps a better one available? Thanks so much! (I also attempted to use an image with only 1 channel, then use a shader to perform a series of if statements to translate various values into other colors. Unfortunately, there were too many lines of code for the shader. It is also rather hacky and does not scale well.)

  • Review my ASP.NET Authentication code.

    - by Niels Bosma
    I have had some problems with authentication in ASP.NET. I'm not used most of the built in authentication in .NET. I gotten some complaints from users using Internet Explorer (any version - may affect other browsers as well) that the login process proceeds but when redirected they aren't authenticated and are bounced back to loginpage (pages that require authentication check if logged in and if not redirect back to loginpage). Can this be a cookie problem? Do I need to check if cookies are enabled by the user? What's the best way to build authentication if you have a custom member table and don't want to use ASP.NET login controls?

  • imagick showing script url instead of image

    - by Raz
    Hi, currently i'm trying to use imagick to generate some images without saving them on the server and then outputting to the browser, my method of choice was image magic with the imagick extension for php. I read the documentation, and i'm sure the package is installed on my machine (windows xp, with xampp). the class is installed imagick module enabled imagick module version 2.0.0-alpha imagick classes Imagick, ImagickDraw, ImagickPixel, ImagickPixelIterator ImageMagick version ImageMagick 6.3.3 04/21/07 Q16 http://www.imagemagick.org ImageMagick release date 04/21/07 ImageMagick Number of supported formats: 164 ImageMagick Supported formats A, ART, AVI, AVS, B, BIE, BMP, BMP2, BMP3, C, CACHE, CAPTION, CIN, CIP, CLIP, CLIPBOARD, CMYK, CMYKA, CUR, CUT, DCM, DCX, DFONT, DPS, DPX, EMF, EPDF, EPI, EPS, EPS2, EPS3, EPSF, EPSI, EPT, EPT2, EPT3, FAX, FITS, FRACTAL, FTS, G, G3, GIF, GIF87, GRADIENT, GRAY, HISTOGRAM, HTM, HTML, ICB, ICO, ICON, INFO, JBG, JBIG, JNG, JP2, JPC, JPEG, JPG, JPX, K, LABEL, M, M2V, MAP, MAT, MATTE, MIFF, MNG, MONO, MPC, MPEG, MPG, MSL, MSVG, MTV, MVG, NULL, O, OTB, OTF, PAL, PALM, PAM, PATTERN, PBM, PCD, PCDS, PCL, PCT, PCX, PDB, PDF, PFA, PFB, PGM, PGX, PICON, PICT, PIX, PJPEG, PLASMA, PNG, PNG24, PNG32, PNG8, PNM, PPM, PREVIEW, PS, PS2, PS3, PSD, PTIF, PWP, R, RAS, RGB, RGBA, RGBO, RLA, RLE, SCR, SCT, SFW, SGI, SHTML, STEGANO, SUN, SVG, SVGZ, TEXT, TGA, THUMBNAIL, TIFF, TILE, TIM, TTC, TTF, TXT, UIL, UYVY, VDA, VICAR, VID, VIFF, VST, WBMP, WMF, WMFWIN32, WMZ, WPG, X, XBM, XC, XCF, XPM, XV, XWD, Y, YCbCr, YCbCrA, YUV this is from the phpinfo so i know i have it installed, the thing is when i try to generate an image and save it, it works flawlessly, but when i try to output the image directly, i get the script url as an image $draw = new ImagickDraw(); $draw->setFont('AnkeCalligraph.TTF'); $draw->setFontSize(52); $draw->annotation(110, 110, "Hello World!"); $draw->annotation(50, 220, "Hello World!"); $canvas = new Imagick('./pictures/test_live.PNG'); $canvas->drawImage($draw); $canvas->setImageFormat('png'); header("Content-Type: image/png"); echo $canvas; this is the code used. if i use writeimage, then the file on the server is created with no problems. does anyone have any ideas what i'm doing wrong ?

  • active_scaffold routing error

    - by Elizabeth Buckwalter
    If you haven't seen my question yesterday, this is my second rails app. The first went nice and smooth, but this one keeps giving me one random error after another. I installed active_scaffold for this app as well as the last app (the first error, instead of using script/install plugin git://active_scaffold repository, I did script/install plugin http://active_scaffold repository.) I didn't want to spell out basic CRUD on minor models. After the install problems, (before I found the http solution from a windows user when I'm on Linux) I thought I'd try out Hobo. Well, Hobo updated actionmailer, actionpack, activerecord, activeresource, and installed rack. Rails isn't even using the updated versions. But as you can see at the bottom of the trace it's using rack. I have a feeling it has something to do with my futzing around with installing Hobo which I uninstalled. Thanks in advanced. [Edit] I had asked the question over at the ActiveScaffold Group the answer (if you don't want to follow the link) was that this line needed to be added to routes: map.resources :modelName, :active_scaffold => true It doesn't entirely answer my question, since the documentation said nothing about changing routes. But, it works. [/Edit] ActionController::RoutingError in Departments#index Showing vendor/plugins/active_scaffold/frontends/default/views/_list_header.html.erb where line #8 raised: No route matches {:_method=:get, :action="show_search", :controller="departments"} Extracted source (around line #8): 5: <% next if controller.respond_to? link.security_method and !controller.send(link.security_method) -%> 6: <% next if link.action == 'new' && params[:nested].nil? && active_scaffold_config.list.always_show_create %> 7: <% next if link.action == 'show_search' && active_scaffold_config.list.always_show_search %> 8: <%= render_action_link(link, new_params) -%> 9: <% end -%> 10: 11: <%= loading_indicator_tag(:action => :table) %> Trace of template inclusion: vendor/plugins/active_scaffold/frontends/default/views/list.html.erb Full Trace It was taking forever to format it.

  • How can I pass latitude and longitude values from UIViewController to MKMapView?

    - by jerincbus
    I have a detail view that includes three UIButtons, each of which pushes a different view on to the stack. One of the buttons is connected to a MKMapView. When that button is pushed I need to send the latitude and longitude variables from the detail view to the map view. I'm trying to add the string declaration in the IBAction: - (IBAction)goToMapView { MapViewController *mapController = [[MapViewController alloc] initWithNibName:@"MapViewController" bundle:nil]; mapController.mapAddress = self.address; mapController.mapTitle = self.Title; mapController.mapLat = self.lat; mapController.mapLng = self.lng; //Push the new view on the stack [[self navigationController] pushViewController:mapController animated:YES]; [mapController release]; //mapController = nil; } And on my MapViewController.h file I have: #import <UIKit/UIKit.h> #import <MapKit/MapKit.h> #import "DetailViewController.h" #import "CourseAnnotation.h" @class CourseAnnotation; @interface MapViewController : UIViewController <MKMapViewDelegate> { IBOutlet MKMapView *mapView; NSString *mapAddress; NSString *mapTitle; NSNumber *mapLat; NSNumber *mapLng; } @property (nonatomic, retain) IBOutlet MKMapView *mapView; @property (nonatomic, retain) NSString *mapAddress; @property (nonatomic, retain) NSString *mapTitle; @property (nonatomic, retain) NSNumber *mapLat; @property (nonatomic, retain) NSNumber *mapLng; @end And on the pertinent parts of the MapViewController.m file I have: @synthesize mapView, mapAddress, mapTitle, mapLat, mapLng; - (void)viewDidLoad { [super viewDidLoad]; [mapView setMapType:MKMapTypeStandard]; [mapView setZoomEnabled:YES]; [mapView setScrollEnabled:YES]; MKCoordinateRegion region = { {0.0, 0.0 }, { 0.0, 0.0 } }; region.center.latitude = mapLat; //40.105085; region.center.longitude = mapLng; //-83.005237; region.span.longitudeDelta = 0.01f; region.span.latitudeDelta = 0.01f; [mapView setRegion:region animated:YES]; [mapView setDelegate:self]; CourseAnnotation *ann = [[CourseAnnotation alloc] init]; ann.title = mapTitle; ann.subtitle = mapAddress; ann.coordinate = region.center; [mapView addAnnotation:ann]; } But I get this when I try to build: 'error: incompatible types in assignment' for both lat and lng variables. So my questions are am I going about passing the variables from one view to another the right way? And does the MKMapView accept latitude and longitude as a string or a number?

  • launching mapview from main activity (button)

    - by arc
    Hi all. Going round in circles here i think. I have an activity called Locate; public class Locate extends Activity { public static String lat; public static String lon; public static String number; public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.locate); final Button buttonMaps = (Button) findViewById(R.id.ButtonMaps); buttonMaps.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { Toast.makeText(getBaseContext(), "Button Pressed", Toast.LENGTH_SHORT).show(); try { Intent i = new Intent(getBaseContext(), displayMap.class); i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); startActivity(i); } catch (ActivityNotFoundException e) { Toast.makeText(getBaseContext(), "Activity Not Found", Toast.LENGTH_SHORT).show(); } }}); // Toast.makeText(getBaseContext(), "lat: " + lat + " long: " + lon + " from: " + testname, Toast.LENGTH_LONG).show(); } If I make the displayMap class into a normal Activity, and just have display a toast message confirming it has loaded - then it works fine. If i do this though; public class displayMap extends MapActivity { /** Called when the activity is first created. */ public void onCreate() { setContentView(R.layout.displaymap); Toast.makeText(getBaseContext(), "Display Map", Toast.LENGTH_SHORT).show(); } @Override protected boolean isRouteDisplayed() { // TODO Auto-generated method stub return false; } } Then as soon as I click the Button, I get a force close. I have the correct 'uses-library' tag in my manifest; <application android:icon="@drawable/icon" android:label="@string/app_name"> <uses-library android:name="com.google.android.maps" /> I don't get what it just force closes everytime i try and load it. If I make this my onClick handler then it will fire up a working googlemaps/default mapview public void onClick(View v) { Toast.makeText(getBaseContext(), "Button Pressed", Toast.LENGTH_SHORT).show(); Uri uri=Uri.parse("geo:"+Locate.lat+","+Locate.lon); StartActivity(new Intent(Intent.ACTION_VIEW, uri)); } But that is not what I am trying to do, I want my own - so that I can add overlays etc to it. But it does prove that the permission are set correctly and that the lib is there. The logcat error when the app FCs is a Unexpected DEX error. Can anyone point in the right direction here?

  • NoSQL DB for .Net document-based database (ECM)

    - by Dane
    I'm halfway through coding a basic multi-tenant SaaS ECM solution. Each client has it's own instance of the database / datastore, but the .Net app is single instance. The documents are pretty much read only (i.e. an image archive of tiffs or PDFs) I've used MSSQL so far, but then started thinking this might be viable in a NoSQL DB (e.g. MongoDB, CouchDB). The basic premise is that it stores documents, each with their own particular indexes. Each tenant can have multiple document types. e.g. One tenant might have an invoice type, which has Customer ID, Invoice Number and Invoice Date. Another tenant might have an application form, which has Member Number, Application Number, Member Name, and Application Date. So far I've used the old method which Sharepoint (used?) to use, and created a document table which has int_field_1, int_field_2, date_field_1, date_field_2, etc. Then, I've got a "mapping" table which stores the customer specific index name, and the database field that will map to. I've avoided the key-value pair model in the DB due to volume of documents. This way, we can support multiple document types in the one table, and get reasonably high performance out of it, and allow for custom document type searches (i.e. user selects a document type, then they're presented with a list of search fields). However, a NoSQL DB might make this a lot simpler, as I don't need to worry about denormalizing the document. However, I've just got concerns about the rest of the data around a document. We store an "action history" against the document. This tracks views, whether someone emails the document from within the system, and other "future" functionality (e.g. faxing). We have control over the document load process, so we can manipulate the data however it needs to be to get it in the document store (e.g. assign unique IDs). Users will not be adding in their own documents, so we shouldn't need to worry about ACID compliance, as the documents are relatively static. So, my questions I guess : Is a NoSQL DB a good fit Is MongoDB the best for Asp.Net (I saw Raven and Velocity, but they're still kinda beta) Can I store a key for each document, and then store the action history in a MSSQL DB with this key? I don't need to do joins, it would be if a person clicks "View History" against a document. How would performance compare between the two (NoSQL DB vs denormalized "document" table) Volumes would be up to 200,000 new documents per month for a single tenant. My current scaling plan with the SQL DB involves moving the SQL DB into a cluster when certain thresholds are reached, and then reviewing partitioning and indexing structures.

  • Need help with implementation of the jQuery LiveUpdate routine

    - by miCRoSCoPiC_eaRthLinG
    Hey all, Has anyone worked with the LiveUpdate function (may be a bit of a misnomer) found on this page? It's not really a live search/update function, but a quick filtering mechanism for a pre-existing list, based on the pattern you enter in a text field. For easier reference, I'm pasting the entire function in here: jQuery.fn.liveUpdate = function(list){ list = jQuery(list); if ( list.length ) { var rows = list.children('li'), cache = rows.map(function(){ return this.innerHTML.toLowerCase(); }); this .keyup(filter).keyup() .parents('form').submit(function(){ return false; }); } return this; function filter(){ var term = jQuery.trim( jQuery(this).val().toLowerCase() ), scores = []; if ( !term ) { rows.show(); } else { rows.hide(); cache.each(function(i){ var score = this.score(term); if (score > 0) { scores.push([score, i]); } }); jQuery.each(scores.sort(function(a, b){return b[0] - a[0];}), function(){ jQuery(rows[ this[1] ]).show(); }); } } }; I have this list, with members as the ID. And a text field with say, qs as ID. I tried binding the function in the following manner: $( '#qs' ).liveUpdate( '#members' ); But when I do this, the function is called only ONCE when the page is loaded (I put in some console.logs in the function) but never after when text is keyed into the text field. I also tried calling the routine from the keyup() function of qs. $( '#qs' ).keyup( function() { $( this ).liveUpdate( '#members' ); }); This ends up going into infinite loops (almost) and halting with "Too much recursion" errors. So can anyone please shed some light on how I am supposed to actually implement this function? Also while you are at it, can someone kindly explain this line to me: var score = this.score(term); What I want to know is where this member method score() is coming from? I didn't find any such method built into JS or jQuery. Thanks for all the help, m^e

  • Network communication for a turn based board game

    - by randooom
    Hi all, my first question here, so please don't be to harsh if something went wrong :) I'm currently a CS student (from Germany, if this info is of any use ;) ) and we got a, free selectable, programming assignment, which we have to write in a C++/CLI Windows Forms Application. My team, two others and me, decided to go for a network-compatible port of the board game Risk. We divided the work in 3 Parts, namely UI, game logic and network. Now we're on the part where we have to get everything working together and the big question mark is, how to get the clients synchronized with each other? Our approach so far is, that each client has all information necessary to calculate and/or execute all possible actions. Actually the clients have all information available at all, aside from the game-initializing phase (add players, select map, etc.), which needs one "super-client" with some extra stuff to control things. This is the standard scenario of our approach: player performs action, the action is valid and got executed on the players client action is sent over the network action is executed on the other clients The design (i.e. no or code so far) we came up with so far, is something like the following pseudo sequence diagram. Gui, Controller and Network implement all possible actions (i.e. all actions which change data) as methods from an interface. So each part can implement the method in a way to get their job done. Example with Action(): On the player side's Client: Player-->Gui.Action() Gui-->Controller.Action() Controller-->Logic.Action (Logic.Action() == NoError)? Controller-->Network.Action() Network-->Parser.ParseAction() Network.Send(msg) On all other clients: Network.Recv(msg) Network-->Parser.Deparse(msg) Parser-->Logic.Action() Logic-->Gui.Action() The questions: Is this a viable approach to our task? Any better/easier way to this? Recommendations, critique? Our knowledge (so you can better target your answer): We are on the beginner side, in regards to programming on a somewhat larger projects with a small team. All of us have some general programming experience and basic understanding of the .Net Libraries and Windows Forms. If you need any further information, please feel free to ask.

  • JQGrid and JQuery Autocomplete

    - by Neff
    When implementing JQGrid 4.3.0, Jquery 1.6.2, and JQuery UI 1.8.16 Ive come across an issue with the Inline edit. When the inline edit is activated, some of the elements get assigned an auto complete. When the inline edit is canceld or saved, the auto complete does not always go away (selecting text by double clicking it then hitting delete, then hitting escape to exit row edit). Leaving the auto complete controls in edit mode when the row is no longer considered in edit mode. Perhaps you can tell me if there is a problem with the initialization or if I you are aware of an event post-"afterrestorefunc" that the fields can be returned to their "original" state. Original state being displayed as data in the JQGrid row. I've tried removing the DOM after row close, .remove() and .empty(): ... "afterrestorefunc": function(){ $('.ui-autocomplete-input').remove(); } ... but that causes other issues, such as the jqgrid is not able to find the cell when serializing the row for data or edit, and requires a refresh of the page, not just jqgrid, to be able to once again see the data from that row. Auto complete functionality for the element is created on the double click of the row: function CreateCustomSearchElement(value, options, selectiontype) { ... var el; el = document.createElement("input"); ... $(el).autocomplete({ source: function (request, response) { $.ajax({ url: '<%=ResolveUrl("~/Services/AutoCompleteService.asmx/GetAutoCompleteResponse") %>', data: "{ 'prefixText': '" + request.term + "', 'contextKey': '" + options.name + "'}", dataType: "json", type: "POST", contentType: "application/json; charset=utf-8", success: function (data) { response($.map(data.d, function (item) { return { label: Trim(item), value: Trim(item), searchVal: Trim(item) } })) } }); }, select: function (e, item) { //Select is on the event of selection where the value and label have already been determined. }, minLength: 1, change: function (event, ui) { //if the active element was not the search button //... } }).keyup(function (e) { if (e.keyCode == 8 || e.keyCode == 46) { //If the user hits backspace or delete, check the value of the textbox before setting the searchValue //... } }).keydown(function (e) { //if keycode is enter key and there is a value, you need to validate the data through select or change(onblur) if (e.keyCode == '13' && ($(el).val())) { return false; } if (e.keyCode == '220') { return false } }); } Other Sources: http://www.trirand.com/jqgridwiki/doku.php?id=wiki:inline_editing http://api.jqueryui.com/autocomplete/ Update: I tried only creating the autocomplete when the element was focused, and removing it when onblur. That did not resolve the issue either. It seems to just need the autocomplete dropdown to be triggered.

  • Putting update logic in your migrations

    - by Daniel Abrahamsson
    A couple of times I've been in the situation where I've wanted to refactor the design of some model and have ended up putting update logic in migrations. However, as far as I've understood, this is not good practice (especially since you are encouraged to use your schema file for deployment, and not your migrations). How do you deal with these kind of problems? To clearify what I mean, say I have a User model. Since I thought there would only be two kinds of users, namely a "normal" user and an administrator, I chose to use a simple boolean field telling whether the user was an adminstrator or not. However, after I while I figured I needed some third kind of user, perhaps a moderator or something similar. In this case I add a UserType model (and the corresponding migration), and a second migration for removing the "admin" flag from the user table. And here comes the problem. In the "add_user_type_to_users" migration I have to map the admin flag value to a user type. Additionally, in order to do this, the user types have to exist, meaning I can not use the seeds file, but rather create the user types in the migration (also considered bad practice). Here comes some fictional code representing the situation: class CreateUserTypes < ActiveRecord::Migration def self.up create_table :user_types do |t| t.string :name, :nil => false, :unique => true end #Create basic types (can not put in seed, because of future migration dependency) UserType.create!(:name => "BASIC") UserType.create!(:name => "MODERATOR") UserType.create!(:name => "ADMINISTRATOR") end def self.down drop_table :user_types end end class AddTypeIdToUsers < ActiveRecord::Migration def self.up add_column :users, :type_id, :integer #Determine type via the admin flag basic = UserType.find_by_name("BASIC") admin = UserType.find_by_name("ADMINISTRATOR") User.all.each {|u| u.update_attribute(:type_id, (u.admin?) ? admin.id : basic.id)} #Remove the admin flag remove_column :users, :admin #Add foreign key execute "alter table users add constraint fk_user_type_id foreign key (type_id) references user_types (id)" end def self.down #Re-add the admin flag add_column :users, :admin, :boolean, :default => false #Reset the admin flag (this is the problematic update code) admin = UserType.find_by_name("ADMINISTRATOR") execute "update users set admin=true where type_id=#{admin.id}" #Remove foreign key constraint execute "alter table users drop foreign key fk_user_type_id" #Drop the type_id column remove_column :users, :type_id end end As you can see there are two problematic parts. First the row creation part in the first model, which is necessary if I would like to run all migrations in a row, then the "update" part in the second migration that maps the "admin" column to the "type_id" column. Any advice?

  • Spring AOP pointcut that matches annotation on interface

    - by seanizer
    Hello, this is my first post here, so I apologize in advance for any stupidity on my side. I have a service class implemented in Java 6 / Spring 3 that needs an annotation to restrict access by role. I have defined an annotation called RequiredPermission that has as its value attribute one or more values from an enum called OperationType: public @interface RequiredPermission { /** * One or more {@link OperationType}s that map to the permissions required * to execute this method. * * @return */ OperationType[] value();} public enum OperationType { TYPE1, TYPE2; } package com.mycompany.myservice; public interface MyService{ @RequiredPermission(OperationType.TYPE1) void myMethod( MyParameterObject obj ); } package com.mycompany.myserviceimpl; public class MyServiceImpl implements MyService{ public myMethod( MyParameterObject obj ){ // do stuff here } } I also have the following aspect definition: /** * Security advice around methods that are annotated with * {@link RequiredPermission}. * * @param pjp * @param param * @param requiredPermission * @return * @throws Throwable */ @Around(value = "execution(public *" + " com.mycompany.myserviceimpl.*(..))" + " && args(param)" + // parameter object " && @annotation( requiredPermission )" // permission annotation , argNames = "param,requiredPermission") public Object processRequest(final ProceedingJoinPoint pjp, final MyParameterObject param, final RequiredPermission requiredPermission) throws Throwable { if(userService.userHasRoles(param.getUsername(),requiredPermission.values()){ return pjp.proceed(); }else{ throw new SorryButYouAreNotAllowedToDoThatException( param.getUsername(),requiredPermission.value()); } } The parameter object contains a user name and I want to look up the required role for the user before allowing access to the method. When I put the annotation on the method in MyServiceImpl, everything works just fine, the pointcut is matched and the aspect kicks in. However, I believe the annotation is part of the service contract and should be published with the interface in a separate API package. And obviously, I would not like to put the annotation on both service definition and implementation (DRY). I know there are cases in Spring AOP where aspects are triggered by annotations one interface methods (e.g. Transactional). Is there a special syntax here or is it just plain impossible out of the box. PS: I have not posted my spring config, as it seems to be working just fine. And no, those are neither my original class nor method names. Thanks in advance, Sean PPS: Actually, here is the relevant part of my spring config: <aop:aspectj-autoproxy proxy-target-class="false" /> <bean class="com.mycompany.aspect.MyAspect"> <property name="userService" ref="userService" /> </bean>

From my searches on the web everything seem to be OK. Any idea?

  • NHibernate - I have many, but I only want one!

    - by MartinF
    Hello, I have a User which can have many Emails. This is mapped through a List collection (exposed by IEnumerable Emails on the User). For each User one of the Emails will be the Primary one ("Boolean IsPrimary" property on Email). How can I get the primary Email from User without NHibernate loads every email for the User ? I have the following two entities, with a corresponding table for each public class User { public virtual int Id { get; set; } public virtual IEnumerable<Email> Emails { get; set; } // public virtual Email PrimaryEmail { get; set; } - Possible somehow ? } public class Email { public virtual int Id { get; set; } public virtual String Address { get; set; } public virtual Boolean IsPrimary { get; set; } public virtual User User { get; set; } } Can I map a "Email PrimaryEmail" property etc. on the User to the Email which have "IsPrimary=1" set somehow ? Maybe using a Sql Formula ? a View ? a One-To-One relationship ? or another way ? It should be possible to change the primary email to be one of the other emails, so i would like to keep them all in 1 table and just change the IsPrimary property. Using a Sql Formula, is it be possible to keep the "PrimaryEmail" property on the User up-to-date, if I set the IsPrimary property on the current primary email to false, and then afterwards set the PrimaryEmail property to the email which should be the new primary email and set IsPrimary to true ? Will NHibernate track changes on the "old/current" primary Email loaded by the Sql Formula ? What about the 1 level cache and the 2 level cache when using SqlFormula ? I dont know if it could work by using a View ? Then i guess the Email could be mapped like a Component ? Will it work when updating the Email data when loaded from the View ? Is there a better way ? As I have a bi-directional relationship between User and Email I could in many cases of course query the primary Email and then use the "User" property on the Email to get the User (instead of the other way around - going from User to the primary Email) Hope someone can help ?

  • How to do an fetch request with expressions like this on the iPhone?

    - by dontWatchMyProfile
    The documentation has an example on how to retrieve simple values only, rather than managed objects. This remembers a lot SQL using aliases and functions to only retrieve calculated values. So, actually pretty geeky stuff. To get the minimum date from a bunch of records, this is used on the mac: NSFetchRequest *request = [[NSFetchRequest alloc] init]; NSEntityDescription *entity = [NSEntityDescription entityForName:@"Event" inManagedObjectContext:context]; [request setEntity:entity]; // Specify that the request should return dictionaries. [request setResultType:NSDictionaryResultType]; // Create an expression for the key path. NSExpression *keyPathExpression = [NSExpression expressionForKeyPath:@"creationDate"]; // Create an expression to represent the minimum value at the key path 'creationDate' NSExpression *minExpression = [NSExpression expressionForFunction:@"min:" arguments:[NSArray arrayWithObject:keyPathExpression]]; // Create an expression description using the minExpression and returning a date. NSExpressionDescription *expressionDescription = [[NSExpressionDescription alloc] init]; // The name is the key that will be used in the dictionary for the return value. [expressionDescription setName:@"minDate"]; [expressionDescription setExpression:minExpression]; [expressionDescription setExpressionResultType:NSDateAttributeType]; // Set the request's properties to fetch just the property represented by the expressions. [request setPropertiesToFetch:[NSArray arrayWithObject:expressionDescription]]; // Execute the fetch. NSError *error; NSArray *objects = [managedObjectContext executeFetchRequest:request error:&error]; if (objects == nil) { // Handle the error. } else { if ([objects count] > 0) { NSLog(@"Minimum date: %@", [[objects objectAtIndex:0] valueForKey:@"minDate"]; } } [expressionDescription release]; [request release]; Nice, I though - but having a deep look into NSExpression -expressionForFunction:arguments: it turns out that iPhone OS does NOT support the min: function. Well, probably there's a nifty way to use an own function for this kind of stuff on the iPhone as well? Because on thing I'm already worrying about is, how I'm gonna sort a table based on the calculated distance of targets on a map (location-based stuff).
