  • accessing layer from class

    - by Mike
    I am creating a rounded corner UIImageView, but this image is created inside a class, using among other instructions, these following: myImageView.layer.cornerRadius = 20.0; myImageView.layer.masksToBounds = YES; myImageView.layer.borderColor = [UIColor darkGrayColor].CGColor; myImageView.layer.borderWidth = 1.0; but Xcode is yelling at me telling me unknown 'cornerRadius' component of a property unknown 'masksToBounds' component of a property unknown 'borderColor' component of a property unknown 'borderWidth' component of a property I know this code is valid, because I have created images like that before, but never inside a class. Why is this happening? how to solve that? thanks.

  • Updating / refreshing a live geojson layer | JSON & JS Variable

    - by Ozaki
    TLDR I am trying to get my geoJSON layer to update, currently it will 1. Create the vector mark, 2. Remove the vector mark, 3. Set the JS variable for lat and lon, 4. Unset the variable??? :S Hey S O. I have a geojson layer set up as follows: //GeoJSON Layer// var layer1 = new OpenLayers.Layer.GML("My GeoJSON Layer", "coordinates", {format: OpenLayers.Format.GeoJSON, styleMap: style_red}); My features are set up as follows: var latitude = 0.0; // as 0.0 it will draw the point in. var longitude = 0.0; // as 0.0 it will draw the point in. //var longitude = getlongitude; where getlongitude = JSON string of longitude. var point = new OpenLayers.Geometry.Point(longitude, latitude); pointFeature = new OpenLayers.Feature.Vector(point, null, style_red); var style_red = OpenLayers.Util.extend({}, layer_style); style_red.strokeColor = "red"; style_red.fillColor = "black"; style_red.fillOpacity = 0.5; style_red.graphicName = "circle"; style_red.pointRadius = 3.8; style_red.strokeWidth = 2; style_red.strokeLinecap = "butt"; and my layer updating function: function UpdateLayer(){ var p = new OpenLayers.Format.GeoJSON({ 'internalProjection': new OpenLayers.Projection("EPSG:900913"), 'externalProjection': new OpenLayers.Projection("EPSG:4326") }); var url = "coordinates"; OpenLayers.loadURL(url, {}, null, function(r) { var f = p.read(r.responseText); map.layers[2].destroyFeatures(); map.layers[2].addFeatures(pointFeature); }); setTimeout("UpdateLayer()",1000) } Any idea what I am doing wrong or what I am missing? Edit1 It now removes the feature (was map.layers[1]) previously... But will not add the new feature.. Edit2 I managed to get it to redraw a point but not with live data. It should draw the point at what (latitude) & (longitude) are equal to. I am trying to set latitude & longitude to some JSON string but every time straight after it sets the variable it changes it back to "undefined" as soon as it passes the line after var latitude? (using firebug & firequery to debug)

  • Calling services from the Orchestrating layer in SOA?

    - by Martin Lee
    The Service Oriented Architecture Principles site says that Service Composition is an important thing in SOA. But Service Loose Coupling is important as well. Does that mean that the "Orchestrating layer" should be the only one that is allowed to make calls to services in the system? As I understand SOA, the "Orchestrating layer" 'glues' all the services together into one software application. I tried to depict that on Fig.A and Fig.B. The difference between the two is that on Fig.A the application is composed of services and all the logic is done in the "Orchestrating layer" (all calls to services are done from the "Orchestrating layer" only). On Fig.B the application is composed from services, but one service calls another service. Does the architecture on Fig.B violate the "Service Loose Coupling" principle of SOA? Can a service call another service in SOA? And more generally, can the architecture on Fig.A be considered superior to the one on Fig.B in terms of service loose coupling, abstraction, reusability, autonomy, etc.? My guess is that the A architecture is much more universal, but it can add some unnecessary data transfers between the "Orchestrating layer" and all the called services.

  • how to call service inside service layer

    - by cometta
    in my service layer public class MyServiceLayerImpl{ @Autowired MyServiceInterface MyServiceLayer } if i have method inside service layer that need to call another service inside service layer. i cannot use this._method ,because, i'm using AOP for caching. In order for the caching to work, i have to use @Autowired to get the service. Therefore, is the above style ok?

  • Passing HttpFileCollectionBase to the Business Layer - Bad?

    - by Terry_Brown
    hopefully there's an easy solution to this one. I have my MVC2 project which allows uploads of files on certain forms. I'm trying to keep my controllers lean, and handle the processing within the business layer of this sort of thing. That said, HttpFileCollectionBase is obviously in the System.Web assembly. Ideally I want to call to something like: UserService.SaveEvidenceFiles(MyUser user, HttpFileCollectionBase files); or something similar and have my business layer handle the logic of how and where these things are saved. But, it feels a little icky to have my models layer with a reference to System.Web in terms of separation of concerns etc. So, we have (that I'm aware of) a few options: the web project handling this, and my controllers getting fatter mapping the HttpFileCollectionBase to something my business layer likes passing the collection through, and accepting that I reference System.Web from my business project Would love some feedback here on best practice approaches to this sort of thing - even if not specifically within the context of the above.

  • What are alternatives to standard ORM in a data access layer?

    - by swampsjohn
    We're all familiar with basic ORM with relational databases: an object corresponds to a row and an attribute in that object to a column (or some slight variation), though many ORMs add a lot of bells and whistles. I'm wondering what other alternatives there are (besides raw access to the database or whatever you're working with). Alternatives that just work with relational databases would be great, but ones that could encapsulate multiple types of backends besides just SQL (such as flat files, RSS, NoSQL, etc.) would be even better. I'm more interested in ideas rather than specific implantations and what languages/platforms they work with, but please link to anything you think is interesting.

  • Master data validation in service layer

    - by rakesh-nitj
    User enters the data in the forms by choosing values from the master data drop downs in web layer. Data is populated in the dropdowns based on some logic from the master data tables and we know for sure that its a valid master data as far as web layer is concern. Now my question is, should be check the validity of the master data in service layer again because we want to use service layer for mulitple interfaces (Web User Interface, Web Services, Unit Test Cases etc.) or we should validate the master data in respective interfaces only.

  • Algorithm to select groups of similar items in 2d array

    - by mafutrct
    There is a 2d array of items (in my case they are called Intersections). A certain item is given as a start. The task is to find all items directly or indirectly connected to this item that satisfy a certain function. So the basic algorithm is like this: Add the start to the result list. Repeat until no modification: Add each item in the array that satisfies the function and touches any item in the result list to the result list. My current implementation looks like this: private IList<Intersection> SelectGroup ( Intersection start, Func<Intersection, Intersection, bool> select) { List<Intersection> result = new List<Intersection> (); Queue<Intersection> source = new Queue<Intersection> (); source.Enqueue (start); while (source.Any ()) { var s = source.Dequeue (); result.Add (s); foreach (var neighbour in Neighbours (s)) { if (select (start, neighbour) && !result.Contains (neighbour) && !source.Contains (neighbour)) { source.Enqueue (neighbour); } } } Debug.Assert (result.Distinct ().Count () == result.Count ()); Debug.Assert (result.All (x => select (x, result.First ()))); return result; } private List<Intersection> Neighbours (IIntersection intersection) { int x = intersection.X; int y = intersection.Y; List<Intersection> list = new List<Intersection> (); if (x > 1) { list.Add (GetIntersection (x - 1, y)); } if (y > 1) { list.Add (GetIntersection (x, y - 1)); } if (x < Size) { list.Add (GetIntersection (x + 1, y)); } if (y < Size) { list.Add (GetIntersection (x, y + 1)); } return list; } (The select function takes a start item and returns true iff the second item satisfies.) This does its job and turned out to be reasonable fast for the usual array sizes (about 20*20). However, I'm interested in further improvements. Any ideas? Example (X satisfies in relation to other Xs, . does never satisfy): .... XX.. .XX. X... In this case, there are 2 groups: a central group of 4 items and a group of a single item in the lower left. Selecting the group (for instance by starting item [2, 2]) returns the former, while the latter can be selected using the starting item and sole return value [0, 3]. Example 2: .A.. ..BB A.AA This time there are 4 groups. The 3 A groups are not connected, so they are returned as separate groups. The bigger A and B groups are connected, but A does not related to B so they are returned as separate groups.

  • Squid - Active Directory - permissions based on Nodes rather than Groups

    - by Genboy
    Hi, I have squid running on a gateway machine & I am trying to integrate it with Active Directory for authentication & also for giving different browsing permissions for different users. 1) /usr/lib/squid/ldap_auth -b OU=my,DC=company,DC=com -h ldapserver -f sAMAccountName=%s -D "CN=myadmin,OU=Unrestricted Users,OU=my,DC=company,DC=com" -w mypwd 2) /usr/lib/squid/squid_ldap_group -b "OU=my,DC=company,DC=com" -f "(&(sAMAccountName=%u)(memberOf=cn=%g,cn=users,dc=company,dc=com))" -h ldapserver -D "CN=myadmin,OU=Unrestricted Users,OU=my,DC=company,DC=com" -w zxcv Using the first command above, I am able to authenticate users. Using the second command above, I am able to figure out if a user belongs to a particular active directory group. So I should be able to set ACL's based on groups. However, my customer's AD setup is such that he has users arranged in different Nodes. For eg. He has users setup in the following way cn=usr1,ou=Lev1,ou=Users,ou=my,ou=company,ou=com cn=usr2,ou=Lev2,ou=Users,ou=my,ou=company,ou=com cn=usr3,ou=Lev3,ou=Users,ou=my,ou=company,ou=com etc. So, he wants that I have different permissions based on whether a user belongs to Lev1 or Lev2 or Lev3 nodes. Note that these aren't groups, but nodes. Is there a way to do this with squid? My squid is running on a debian machine.

  • Referencing groups/classes from Puppet dashboard in my site manifest

    - by Banjer
    I'm using Puppet Dashboard as my ENC and I'm not sure how to reference or use class and group classifications from /etc/puppet/manifests/site.pp. I have two groups defined in the dashboard: CentOS6 and SLES11. What should my site.pp look like if I want to include a certain list of modules in the CentOS6 group and a certain list of modules in the SLES11 group? I'm trying to do something like this: # /etc/puppet/manifests/site.pp node basenode { include hosts include ssh::server include ssh::client include authentication include sudo include syslog include mail } node 'CentOS6' inherits basenode { include profile } node 'SLES11' inherits basenode { include usrmounts } I have OS-specific case statements within my modules, but there are some modules that will only be applied to a certain distro. So I suppose I have two questions: Is this the best way to apply modules/resources in an OS-specific manner? Or does the above make you want to vomit? Regardless of #1, I'm still curious as how to reference classes, groups, and nodes from Dashboard within my manifests. I've read the External Nodes doc, but I'm not seeing how they correspond to manifests. Thanks all.

  • 1000Base-X layer 2/MAC address details

    - by user69971
    A layer 2 Ethernet frame is sent with a source and destination MAC address. Given a 100Base-TX (copper) trunk between two Cisco switches, I can do a "show interface fa 0/0" on S1 to see the MAC address assigned to the trunking interface, then go to Switch2 and do a "show mac address-table" and find the MAC address of the S1 fa 0/0 interface as a dynamically learned MAC in the table. Given a similar setup with a 1000Base-X (fiber GBIC) trunk, the MAC address shown in "show interface gi 0/0" on S1 does not show up in the MAC address-table of S2. Everything I can find online indicates that 1000Base-X uses largely the same layer 2 format as copper connections. There's some slight alterations - minimum frame size is slightly larger - but the fundamentals of the frame structure appear to be the same, including transmission with a source and destination L2 address. Why doesn't the address of gi 0/0 show up in the MAC address table of the connection switch? The only thing which seems to make sense would be that the GBIC has its own MAC address, almost as if its acting as a mini 2-port switch or hub, with the switch-assigned MAC address showing up on the interface connection and a different MAC address assigned to the fiber side. If this is the case, is there any way to see the GBIC MAC address on the switch? (I've tried to look up the details in IEEE 802.3z but it doesn't seem to be available without an IEEE membership or purchasing the standard. I find the base 802.3 PDFs for download, but not 802.3z.)

  • Deploy an AWS Auto Scaling groups using Chef Server

    - by Yoga
    You can, for example, to deploy an an Auto Scaling groups consists of web severs, ELB and DB using AWS CloudFormation (with Chef server): http://aws.amazon.com/cloudformation/aws-cloudformation-templates/ But, you need to initially create a CF template, is it possible to do it only using Chef Server and Knife? We don't want to rely much on the CloudFormation and seems the hosted Chef server at (http://www.opscode.com/) is able to do so. Any opensource alternative? Thanks.

  • How to open the Select Users, Computers, Service Accounts or Groups

    - by Dave Rook
    The only way I know how to open the Select Users, Computers, Service Accounts or Groups is by right clicking on a folder and selecting Properties - Security Tab - Edit - Advanced. Below is a screen shot of the window I want to access: Is there any other way to view the full list (Find Now)? I am writing documentation and I want the user to check if a user exists before creating it. I would ideally like them to access this via control panel or similar.

  • Empty "Groups" in People Picker Navigation Controller

    - by Meltemi
    I'm using the standard People Picker Navigation Controller to let users associate one of their contacts with one of my objects. It presents itself as a long list of ALL contacts. The back button (top left) says "Groups" but when clicked on it shows an empty screen...even when there are many Groups in the user's address book. I've read through the docs and can't seem to find how to populate the Groups area. Here's how I present the people picker. Fairly standard: - (IBAction)showPicker:(id)sender { ABPeoplePickerNavigationController *picker = [[ABPeoplePickerNavigationController alloc] init]; picker.peoplePickerDelegate = self; [self presentModalViewController:picker animated:YES]; [picker release]; } What am I missing?

  • Architecture for a business objects / database access layer

    - by gregmac
    For various reasons, we are writing a new business objects/data storage library. One of the requirements of this layer is to separate the logic of the business rules, and the actual data storage layer. It is possible to have multiple data storage layers that implement access to the same object - for example, a main "database" data storage source that implements most objects, and another "ldap" source that implements a User object. In this scenario, User can optionally come from an LDAP source, perhaps with slightly different functionality (eg, not possible to save/update the User object), but otherwise it is used by the application the same way. Another data storage type might be a web service, or an external database. There are two main ways we are looking at implementing this, and me and a co-worker disagree on a fundamental level which is correct. I'd like some advice on which one is the best to use. I'll try to keep my descriptions of each as neutral as possible, as I'm looking for some objective view points here. Business objects are base classes, and data storage objects inherit business objects. Client code deals with data storage objects. In this case, common business rules are inherited by each data storage object, and it is the data storage objects that are directly used by the client code. This has the implication that client code determines which data storage method to use for a given object, because it has to explicitly declare an instance to that type of object. Client code needs to explicitly know connection information for each data storage type it is using. If a data storage layer implements different functionality for a given object, client code explicitly knows about it at compile time because the object looks different. If the data storage method is changed, client code has to be updated. Business objects encapsulate data storage objects. In this case, business objects are directly used by client application. Client application passes along base connection information to business layer. Decision about which data storage method a given object uses is made by business object code. Connection information would be a chunk of data taken from a config file (client app does not really know/care about details of it), which may be a single connection string for a database, or several pieces connection strings for various data storage types. Additional data storage connection types could also be read from another spot - eg, a configuration table in a database that specifies URLs to various web services. The benefit here is that if a new data storage method is added to an existing object, a configuration setting can be set at runtime to determine which method to use, and it is completely transparent to the client applications. Client apps do not need to be modified if data storage method for a given object changes. Business objects are base classes, data source objects inherit from business objects. Client code deals primarily with base classes. This is similar to the first method, but client code declares variables of the base business object types, and Load()/Create()/etc static methods on the business objects return the appropriate data source-typed objects. The architecture of this solution is similar to the first method, but the main difference is the decision about which data storage object to use for a given business object is made by the business layer, not the client code. I know there are already existing ORM libraries that provide some of this functionality, but please discount those for now (there is the possibility that a data storage layer is implemented with one of these ORM libraries) - also note I'm deliberately not telling you what language is being used here, other than that it is strongly typed. I'm looking for some general advice here on which method is better to use (or feel free to suggest something else), and why.

  • adldap class, need to search for user in two groups

    - by Brad
    http://adldap.sourceforge.net/wiki/doku.php?id=api_user_functions#user_ingroup_username_group_recursive_null I am using the adLDAP class above to authenticate users against our ldap server. I was wondering how I could check multiple groups to see if the user belongs to either, if they belong to either. I don't know if user_ingroup($username,$group,$recursive=NULL); can handle search two different groups for the user, need help coding it to search for the user in two different groups, and as soon as it finds it in one of those, break the operation and set a variable to true. Any help is appreciated.

  • Entities groups in transactions

    - by Joel
    In the context of "Keys and Entity Groups" article by google: http://code.google.com/appengine/docs/python/datastore/transactions.html 1) "Only use entity groups when they are needed for transactions" 2) "Every entity belongs to an entity group, a set of one or more entities that can be manipulated in a single transaction." It seems like entity groups exist only for the use of transactions, i.e. making one transaction possible between all entities in a group. My question is then why are there parent-child relations between entities and not just a simple declaration of entities to be in a single group (that is defining A,B,C to be in the same group as opposed to defining relations between them "A (parent of) B, B (parent of C)"). What is the benefit from using parent-child relation model when the only purpose is for entities to be in the same group to make transaction possible? Thanks Joel

  • How do I create regex groups for replacement?

    I have this sample string: Image: SGD$45.32 SKU: 3f3f3 dfdfd grg4t BP 6yhf Pack Size: 1000's Color: Green Price: SGD$45.32 SGD$45... I would like to remove all the prices namely: SGD$45.32 Price: SGD$45.32 SGD$45 I have this expression thats supposed to match the 3 groups: $pattern = '/(Price.+\sSGD\$\d+\.\d{2})(SGD\$\d+\.\d{2})(SGD\$\d+)/'; $new_snippet = preg_replace($pattern, '', $snippet);` But apparently its not working. It works if I replace a single group at a time. But, I'd like to know if it possible to replace all possible matching groups with a single statement. Tried preg_match_all($pattern, $snippet, $matches); to show matches based on the above pattern, but no matches are found if I put all 3 groups together.
