  • Java Simple WGS84 Lat Lon to Pixel X, Y

    - by Cnich
    I've read a multitude of information regarding map projection today. The amount of information available is overwhelming. I am attempting to simply convert lat, long values into a screen X, Y coordinate not using any map. I do not need the values projected onto any map, just on the window. The window itself is representing approx. a 1500x1500 meter location. Lat, Long accuracy needed is to a 1/10th of a second. What may be some simpler ways in converting lat/long representation to the screen? I've read several articles and post regarding translation onto images, but nothing related to the natural java coordinate system. Thanks for any insight.

  • Add UIProgressView to a custom UITableViewCell and detect what is the index row

    - by Piero
    i create a custom UITableViewCell and i add on the Cell a UIProgressView, because when i add a row on the UITableView i download the information from a XML data, and i want use the ProgressView to show the progress of the process, my question is, how i can detect in what index row i have to change the progress bar, and then hidden it?...what is the index path of the row just created? in the: cellForRowAtIndexPath:(NSIndexPath *)indexPath i retrieve information from my Custom UITableViewCell in this way: UILabel *label; label = (UILabel *)[cell viewWithTag:1000]; label.text = [[managedObject valueForKey:@"firstName"] description]; so how i can know the index path row of the row just added, to change then the progress bar?

  • Reporting Services: Two Tables One Sum

    - by Neomoon
    My report is as follows: One table provides financial information with sums at the group footer (Grouping is called "StockTable_Shipped"). The group is controlled by a boolean value (1=shows shipped data, 0 = shows received data) The second table is a variance report for data that has been shipped (boolean value of 1) and has a sum at the bottom of the table. My ultimate goal is to take the sum from table1 where shipped=1 and subtract it from the variance sum from table2. This will be placed in a textbox at the bottom of the report. I understand if this sounds confusing but I would be more then happy to provide more information.

  • Closing ASPxPopupControl and Reset Login Dialogs

    - by Fitzroy Wright
    I am creating a login usercontrol. I have added the following buttons: Recover Password, Change Password & Edit Profile. I am using DevExpress's ASPxPopupControl to host the functions associated with those three buttons. There are two problems When the popup is opened I need to be able to close/hide it using a command button When a user starts using one of the login controls and chooses to close the dialog the next time the dialog is opened it does not start at the beginning. (e.g. Start the change password dialog, enter some information, close the popup; the information you started with is not cleared) Any ideas?

  • Reading EventLog C# Errors

    - by Robert
    I have this code in my ASP.NET application written in C# that is trying to read the eventlog, but it returns an error. EventLog aLog = new EventLog(); aLog.Log = "Application"; aLog.MachineName = "."; // Local machine foreach (EventLogEntry entry in aLog.Entries) { if (entry.Source.Equals("tvNZB")) Label_log.Text += "<p>" + entry.Message; } One of the entries it returns is "The description for Event ID '0' in Source 'tvNZB' cannot be found. The local computer may not have the necessary registry information or message DLL files to display the message, or you may not have permission to access them. The following information is part of the event:'Service started successfully.'" I only want the 'Service started successfully'. Any ideas?

  • Run MySQL INSERT Query multiple times (insert values into multiple tables)

    - by Derek
    Hi, basically, I have 3 tables; users and projects (which is a many-to-many relationship), then I have 'usersprojects' to allow the one-to-many formation. When a user adds a project, I need the project information stored and then the 'userid' and 'projectid' stored in the usersprojects table. It sounds like its really straight forward but I'm having problems with the syntax I think!? As it stands, I have this as my INSERT queries (values going into 2 different tables): $project_id = $_POST['project_id']; $projectname = $_POST['projectname']; $projectdeadline = $_POST['projectdeadline']; $projectdetails = $_POST['projectdetails']; $user_id = $_POST['user_id']; $sql = "INSERT INTO projects (projectid, projectname, projectdeadline, projectdetails) VALUES ('{$projectid}','{$projectname}','{$projectdeadline}','{$projectdetails}')"; $sql = "INSERT INTO usersprojects (userid, projectid) VALUES ('{$userid}','{$projectid}')"; None of the information is being stored in the projects table, but the user ID is being stored in the usersprojects table (but not project ID!?)... I did have it working where the project information is stored correctly with a project ID, before I added this bit: $sql = "INSERT INTO usersprojects (userid, projectid) VALUES ('{$userid}','{$projectid}')"; But before the code above was put in, obviously no info is being stored in usersprojects table. The source code that links the script: <form id="addform" name="addform" method="POST" action="addproject-run.php"> <label>Project Name:</label> <input name="projectname" size="40" id="projectname" value="<?php if (isset($_POST['projectname'])); ?>"/><br /> <input name="user_id" input type="hidden" size="40" id="user_id" value="<?php echo $_SESSION['SESS_USERID']; ?>"/> <label>Project Deadline:</label> <input name="projectdeadline" size="40" id="projectdeadline" value="In the format of 'YYYY-MM-DD'<?php if (isset($_POST['projectdeadline'])); ?>"/><br /> <label>Project Details:</label> <textarea rows="5" cols="20" name="projectdetails" id="projectdetails"><?php if (isset($_POST['projectdetails'])); ?></textarea> <br /> <br /> <input value="Create Project" class="addbtn" type="submit" /> </form></div> So I think I'm right in saying I have the syntax for the SQL statement to be run an insert query of values into 2 tables? Any help is much appreciated! Thanks.

  • Disable browser 'Save Password' functionality

    - by mattsmith321
    One of the joys of working for a government healthcare agency is having to deal with all of the paranoia around dealing with PHI (Protected Health Information). Don't get me wrong, I'm all for doing everything possible to protect people's personal information (health, financial, surfing habits, etc.), but sometimes people get a little too jumpy. Case in point: One of our state customers recently found out that the browser provides the handy feature to save your password. We all know that it has been there for a while and is completely optional and is up to the end user to decide whether or not it is a smart decision to use or not. However, there is a bit of an uproar at the moment and we are being demanded to find a way to disable that functionality for our site. Question: Is there a way for a site to tell the browser not to offer to remember passwords? I've been around web development a long time but don't know that I have come across that before. Any help is appreciated. Thanks, Matt

  • 'NoneType' object has no attribute 'get' error using SQLAlchemy

    - by Az
    I've been trying to map an object to a database using SQLAlchemy but have run into a snag. Version info if handy: [OS: Mac OSX 10.5.8 | Python: 2.6.4 | SQLAlchemy: 0.5.8] The class I'm going to map: class Student(object): def __init__(self, name, id): self.id = id self.name = name self.preferences = collections.defaultdict(set) self.allocated_project = None self.allocated_rank = 0 def __repr__(self): return str(self) def __str__(self): return "%s %s" %(self.id, self.name) Background: Now, I've got a function that reads in the necessary information from a text database into these objects. The function more or less works and I can easily access the information from the objects. Before the SQLAlchemy code runs, the function will read in the necessary info and store it into the Class. There is a dictionary called students which stores this as such: students = {} students[id] = Student(<all the info from the various "reader" functions>) Afterwards, there is an "allocation" algorithm that will allocate projects to student. It does that well enough. The allocated_project remains as None if a student is unsuccessful in getting a project. SQLAlchemy bit: So after all this happens, I'd like to map my object to a database table. Using the documentation, I've used the following code to only map certain bits. I also begin to create a Session. from sqlalchemy import * from sqlalchemy.orm import * engine = create_engine('sqlite:///:memory:', echo=False) metadata = MetaData() students_table = Table('studs', metadata, Column('id', Integer, primary_key=True), Column('name', String) ) metadata.create_all(engine) mapper(Student, students_table) Session = sessionmaker(bind=engine) sesh = Session() Now after that, I was curious to see if I could print out all the students from my students dictionary. for student in students.itervalues(): print student What do I get but an error: Traceback (most recent call last): File "~/FYP_Tests/FYP_Tests.py", line 140, in <module> print student File "/~FYP_Tests/Parties.py", line 30, in __str__ return "%s %s" %(self.id, self.name) File "/opt/local/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/SQLAlchemy-0.5.8-py2.6.egg/sqlalchemy/orm/attributes.py", line 158, in __get__ return self.impl.get(instance_state(instance), instance_dict(instance)) AttributeError: 'NoneType' object has no attribute 'get' I'm at a loss as to how to resolve this issue, if it is an issue. If more information is required, please ask and I will provide it.

  • Silverlight 4 HttpWebRequest user agent string is null

    - by Dan B
    The problem I have a page with a silverlight object. It attempts to retrieve XML from the page. But I am struggling with a security exception. I have this code working brilliantly in WPF. When using a website hosting a silverlight application with the same code, the user agent string of the HttpRequest object is null (and seemingly cannot be set). In fact there is no header information at all - this causes a security exception when attempting to make my asynchronous call. The question Why is the user-agent string (and header information) null in my silverlight 4 application when making an asynchronous call using HttpWebRequest? Thanks in advance!

  • Single Sign On for a Web App

    - by Jeremy Goodell
    I have been trying to understand how this problem is solved for over a month now. I really need to come up with a general approach that works -- I'm basically the only resource who can do it. I have a theory, but I'm just not sure it's the easiest (or correct) approach and I haven't been able to find any information to support my ideas. Here's the scenario: 1) You have a complex web application that offers secure content on a subscription basis. 2) Users are required to log in to your application with user name and password. 3) You sell to large corporations, which already have a corporate authentication technology (for example, Active Directory). 4) You would like to integrate with the corporate authentication mechanism to allow their users to log onto your Web App without having to enter their user name and password. Now, any solution you come up with will have to provide a mechanism for: adding new users removing users changing user information allowing users to log in Ideally, all these would happen "automagically" when the corporate customer made the corresponding changes to their own authentication. Now, I have a theory that the way to do this (at least for Active Directory) would be for me to write a client-side app that integrates with the customer's Active Directory to track the targeted changes, and then communicate those changes to my Web App. I think that if this communication were done via Web Services offered by my web app, then it would maintain an unhackable level of security, which would obviously be a requirement for these corporate customers. I've found some information about a Microsoft product called Active Directory Federation Service (ADFS) which may or may not be the right approach for me. It seems to be a bit bulky and have some requirements that might not work for all customers. For other existing ID scenarios (like Athens and Shibboleth), I don't think a client application is necessary. It's probably just a matter of tying into the existing ID services. I would appreciate any advice anyone has on anything I've mentioned here. In particular, if you can tell me if my theory is correct about providing a client-side app that communicates with server-side Web Services, or if I'm totally going in the wrong direction. Also, if you could point me at any web sites or articles that explain how to do this, I'd really appreciate it. My research has not turned up much so far. Finally, if you could let me know of any Web applications that currently offer this service (particularly as tied to a corporate Active Directory), I would be very grateful. I am wondering if other B2B Web app's like salesforce.com, or hoovers.com offer a similar service for their corporate customers. I hate being in the dark and would greatly appreciate any light you can shed ... Jeremy

  • Alternative site to Mike Gunderloy's "The Daily Grind" (Larkware)?

    - by splattne
    As a developer who is always looking for new resources and information, I loved Mike Gunderloy's blog "The Daily Grind" on www.larkware.com ("We get up early, so you don't have to.") Unfortunately (for me) Mike decided to discontinue the blog in December 2007. So, my question: is there a similar blog / site which provides such good links and resources on a daily basis? I couldn't find one. Thanks! Update: to be clear: I am specifically looking for a site like larkware.com, a kind of aggregator/meta-site of information about interesting articles, components, software for (.NET) developers.

  • Grails GIS Application

    - by Steve Wall
    Hello, I'm working on an internal IT application monitoring outages for a network with a national footprint in the US. I'm considering overlaying outages by region on a map. Showing outage areas in red for example. The user clicks on the outage area displaying drill down information. The technology stack includes Grails/JBoss/Linux. Are there frameworks that provide the mapping/GIS layer of the display on which I could overly my domain specific information? I've looked into the Google Map API, but am unable to leverage it as this operates behind a firewall. Any ideas? Thanks in advance, Steve

  • Random "Not Found" error with Silverlight accessing ASP.NET Web Services

    - by user245822
    I'm developing an application with Silverlight 3 and ASP.NET Web Services, which uses Linq to SQL to get data from my SQL Server database. Randomly when the user causes an action to get information from any of my web service methods, Silverlight throws the exception "The remote server returned an error: NotFound.", of type "CommunicationException", with the InnerException status of "System.Net.WebExceptionStatus.UnknownError". Almost 10% of requests gets this error. If the user tries to get the same information again, normally the request has no erros and the user gets the data. When debugging in Visual Studio only Silverlight stops on the exception, and I see no reason for the web service not being found.

  • Is That REST API Really RPC? Roy Fielding Seems to Think So.

    - by Rich Apodaca
    A large amount of what I thought I knew about REST is apparently wrong - and I'm not alone. This question has a long lead-in, but it seems to be necessary because the information is a bit scattered. The actual question comes at the end if you're already familiar with this topic. From the first paragraph of Roy Fielding's REST APIs must be hypertext-driven, it's pretty clear he believes his work is being widely misinterpreted: I am getting frustrated by the number of people calling any HTTP-based interface a REST API. Today’s example is the SocialSite REST API. That is RPC. It screams RPC. There is so much coupling on display that it should be given an X rating. Fielding goes on to list several attributes of a REST API. Some of them seem to go against both common practice and common advice on SO and other forums. For example: A REST API should be entered with no prior knowledge beyond the initial URI (bookmark) and set of standardized media types that are appropriate for the intended audience (i.e., expected to be understood by any client that might use the API). ... A REST API must not define fixed resource names or hierarchies (an obvious coupling of client and server). ... A REST API should spend almost all of its descriptive effort in defining the media type(s) used for representing resources and driving application state, or in defining extended relation names and/or hypertext-enabled mark-up for existing standard media types. ... The idea of "hypertext" plays a central role - much more so than URI structure or what HTTP verbs mean. "Hypertext" is defined in one of the comments: When I [Fielding] say hypertext, I mean the simultaneous presentation of information and controls such that the information becomes the affordance through which the user (or automaton) obtains choices and selects actions. Hypermedia is just an expansion on what text means to include temporal anchors within a media stream; most researchers have dropped the distinction. Hypertext does not need to be HTML on a browser. Machines can follow links when they understand the data format and relationship types. I'm guessing at this point, but the first two points above seem to suggest that API documentation for a Foo resource that looks like the following leads to tight coupling between client and server and has no place in a RESTful system. GET /foos/{id} # read a Foo POST /foos/{id} # create a Foo PUT /foos/{id} # update a Foo Instead, an agent should be forced to discover the URIs for all Foos by, for example, issuing a GET request against /foos. (Those URIs may turn out to follow the pattern above, but that's beside the point.) The response uses a media type that is capable of conveying how to access each item and what can be done with it, giving rise to the third point above. For this reason, API documentation should focus on explaining how to interpret the hypertext contained in the response. Furthermore, every time a URI to a Foo resource is requested, the response contains all of the information needed for an agent to discover how to proceed by, for example, accessing associated and parent resources through their URIs, or by taking action after the creation/deletion of a resource. The key to the entire system is that the response consists of hypertext contained in a media type that itself conveys to the agent options for proceeding. It's not unlike the way a browser works for humans. But this is just my best guess at this particular moment. Fielding posted a follow-up in which he responded to criticism that his discussion was too abstract, lacking in examples, and jargon-rich: Others will try to decipher what I have written in ways that are more direct or applicable to some practical concern of today. I probably won’t, because I am too busy grappling with the next topic, preparing for a conference, writing another standard, traveling to some distant place, or just doing the little things that let me feel I have I earned my paycheck. So, two simple questions for the REST experts out there with a practical mindset: how do you interpret what Fielding is saying and how do you put it into practice when documenting/implementing REST APIs? Edit: this question is an example of how hard it can be to learn something if you don't have a name for what you're talking about. The name in this case is "Hypermedia as the Engine of Application State" (HATEOAS).

  • Advice? SSO in N-tiered SOA with mixture of REST and SOAP services

    - by Tyler
    Hi gang, We are moving to SSO in our N-tiered SOA applications. If all the services were SOAP, I'd be ok with just the WS-Security, WS-Trust, WS-Federation set of protocols. My problem is that many of the services are RESTful (ironic) and those protocols do not address REST services. What is your advice for SSO protecting the REST services in an N-tiered SOA architecture with the following requirements: ideally claims-based identity information available to the REST services original user (eg. bootstrap) information must flow through the tiers so that each service can "ActAs" or "OnBehalfOf" the user support sequences like: WebApp -- REST Svc -- SOAP Svc WebApp -- REST Svc1 -- REST Svc2 WebApp -- SOAP Svc -- REST Svc WebApp -- SOAP Svc1 -- SOAP Svc2 support SSO (and SSOff) service/web app platforms: ASP.Net and WCF Java end-user client platforms: .Net (WSE 3.0 and WCF) flash 10 java javascript and AJAX Normally I'm good at climbing / bashing my way through walls, but this one's knocked me flat. Hopefully with your help, we can get over this one. Thanks, Tyler

  • Powerpoint Add-In: Add a Button to PPT to SyntaxHighlight a Textbox

    - by Tigraine
    Hi Guys, I am trying to write an Add-In to Powerpoint that does basically one thing: Give users a Button somewhere to click, once they click on it the currently selected TextField should get syntax highlighted. The Syntax highlighting part is easy, I'm just having a real hard time finding some good information on how to successfully interact with Powerpoint from code. There are some MSDN articles highlighting how to add controls on document start or AddSlide, but no good information on how to extend the UI. Has anyone had some experience in this field and could point me to some resource that may help? Also, I am running Powerpoint 2007 while my customer may end up running PPT2003. How is the backwards compatibility of the Add-ins? greetings Daniel

  • TimeoutException in simultaneous calls to WCF services from Silverlight application

    - by Alexander K.
    Analysing log files I've noticed that ~1% of service calls ended with TimeoutException on the Silverlight client side. The services (wcf) are quite simple and do not perform long computations. According the log all calls to the services are always processed in less that 1 sec (even when TimeoutException is occurred on the client!), so it is not server timeout. So what is wrong? Can it be configuration or network problem? How can I avoid it? What additional logging information can be helpful for localizing this issue? The only one workaround I've thought up is to retry service calls after timeout. I will appreciate any help on this issue! Update: On startup the application performs 17 service calls and 12 of them simultaneously (may it be cause of failure?). Update: WCF log has not contained useful information about this issue. It seems some service calls do not reach the server side.

  • OpenLDAP and user role based accedss controll (RBAC)

    - by Jason
    Hello, my company uses an openldap server which stores corporate user information ((username,passwd and some other information like email are stored in ldap).. Till now they only use it for authentication but now we'd like to use for authentication also, this means that we'll create roles (as ldap attributes in a new schema) and assign those roles in the users. My actual question is if there is a best-practice to follow for using openldap for authentication on many applications (most written in php). I understand how to make roles and assign them to users for just one application, but what about the others (each application of course has its own roles). Should I just create an ou=appName,ou=roles,dc=mycompany for each application, put the roles as attributes there and just add each role as an attribute of the user object ? is there any other recommendations ? thanks

  • US Bank Routing Number and BIC/SWIFT

    - by Konerak
    I know it is a bit offtopic, but I've been having a hard time finding more information to this question, and since this site is visited by a lot of people from the United States, you guys might know/find the answer more easily. Banks in europe each have a SWIFT Number, while US Banks use Routing Numbers. This leads to following questions: Does each bank in the US also carry a BIC number? (SWIFT) Is there a 1-1 relationship between BIC/SWIFT and Routing Numbers? Is there a list of these numbers somewhere? Background information: We're adding international payments to our bookkeeping application. Users can add international suppliers, but my boss prefered not to change the current supplier table but to have the ROUTING NUMBER in another table, with as PK the BIC. I'm wondering if BIC is a valid choice, or if it should just be BANK ACCOUNT NUMBER.

  • Capturing network traffic in ruby - pcap related issues

    - by Acidburn2k
    What I need is to write very simple application, which would listen to network traffic, filter out some packets based on various layer 4/5 information and then dump those information into database. I am quite confused on which pcap gem/plugin should I use. The basic pcap implemention seem to be a bit outdated (no changes since 2001) and doesn't work properly. I also tried pcaprub, but I am not quite sure how to get around with this library. It seem to capture raw packets without te ability to actualy get any data out of the pcap dump. Do you have any advices on how can I realize this simple task? Thanks in advance. :-)

  • Django auth without "auth_*" tables

    - by Travis Jensen
    We would like to use our own tables for user management instead of the Django "auth" tables. We already have database tables that include all of the relevant information our application needs but it isn't in the Django format. We would prefer not to have the information duplicated in two tables. We would like to utilize the auth package, though, as there is some very nice functionality that we don't want to replicate. I realize we could build our own auth backend, but that doesn't, as far as I can tell, remove the need for two sets of tables in this case. Am I correct in assuming that we cannot do this? I have found no docs that discuss how to modify the underlying model that the auth package is using. The backend simply pre-populates the user object that would eventually be saved in the auth tables. Thanks!

  • Code Camp 2011 – Summary

    - by hajan
    Waiting whole twelve months to come this year’s Code Camp 2011 event was something which all Microsoft technologies (and even non-Microsoft techs.) developers were doing in the past year. Last year’s success was enough big to be heard and to influence everything around our developer community and beyond. Code Camp 2011 was nothing else but a invincible success which will remain in our memory for a long time from now. Darko Milevski (president of MKDOT.NET UG and SharePoint MVP) said something interesting at the event keynote that up to now we were looking at the past by saying what we did… now we will focus on the future and how to develop our community more and more in the future days, weeks, months and I hope so for many years… Even though it was held only two days ago (26th of November 2011), I already feel the nostalgia for everything that happened there and for the excellent time we have spent all together. ORGANIZED BY ENTHUSIASTS AND EXPERTS Code Camp 2011 was organized by number of community enthusiasts and experts who have unselfishly contributed with all their free time to make the best of this event. The event was organized by a known community group called MKDOT.NET User Group, name of a user group which is known not only in Macedonia, but also in many countries abroad. Organization mainly consists of software developers, technical leaders, team leaders in several known companies in Macedonia, as well as Microsoft MVPs. SPEAKERS There were 24 speakers at five parallel tracks. At Code Camp 2011 we had two groups of speakers: Professional Experts in various technologies and Student Speakers. The new interesting thing here is the Student Speakers, which draw attention a lot, especially to other students who were interested to see what their colleagues are going to speak about and how do they use Microsoft technologies in different coding scenarios and practices, in different topics. From the rest of the professional speakers, there were 7 Microsoft MVPs: Two ASP.NET/IIS MVPs, Two C# MVPs, and One MVP in SharePoint, SQL Server and Exchange Server. I must say that besides the MVP Speakers, who definitely did a great job as always… there were other excellent speakers as well, which were speaking on various technologies, such as: Web Development, Windows Phone Development, XNA, Windows 8, Games Development, Entity Framework, Event-driven programming, SOLID, SQLCLR, T-SQL, e.t.c. SESSIONS There were 25 sessions mainly all related to Microsoft technologies, but ranging from Windows 8, WP7, ASP.NET till Games Development, XNA and Event-driven programming. Sessions were going in five parallel tracks named as Red, Yellow, Green, Blue and Student track. Five presentations in each track, each with level 300 or 400. More info MY SESSION (ASP.NET MVC Best Practices) I must say that from the big number of speaking engagements I have had, this was one of my best performances and definitely I have set new records of attendees at my sessions and probably overall. I spoke on topic ASP.NET MVC Best Practices, where I have shown tips, tricks, guidelines and best practices on what to use and what to avoid by developing with one of the best web development frameworks nowadays, ASP.NET MVC. I had approximately 350+ attendees, the hall was full so that there was no room for staying at feet. Besides .NET developers, there were a lot of other technology oriented developers, who has also received the presentation very well and I really hope I gave them reason to think about ASP.NET as one of the best options for web development nowadays (if you ask me, it’s the best one ;-)). I have included 10 tips in using ASP.NET MVC each of them followed by a demo. Besides these 10 tips, I have briefly introduced the concept of ASP.NET MVC for those that haven’t been working with the framework and at the end some bonus tips. I must say there was lot of laugh for some funny sentences I have stated, like “If you code ASP.NET MVC, girls will love you more” – same goes for girls, only replace girls with boys :). [LINK TO SESSION WILL GO HERE, ONCE SESSIONS ARE AVAILABLE ON MK CODECAMP WEBSITE] VOLUNTEERS Without strong organization, such events wouldn’t be able to gather hundreds of attendees at one place and still stay perfectly organized to the smallest details, without dedicated organization and volunteers. I would like to dedicate this space in my blog to them and to say one big THANK YOU for supporting us before the event and during the whole day in the event. With such young and dedicated volunteers, we couldn’t achieve anything but great results. THANK YOU EVERYONE FOR YOUR CONTRIBUTION! NETWORKING One of the main reasons why we do such events is to gather all professionals in one place. Networking is what everyone wants because through this way of networking, we can meet incredible people in one place. It is amazing feeling to share your knowledge with others and exchange thoughts on various topics. Meet and talk to interesting people. I have had very special moments with many attendees especially after my presentation. Special Thank You to all of them who come to meet me in person, whether to ask a question, say congrats for my session or simply meet me and just smile :)… everything counts! Thank You! TWITTER During the event, twitter was one of the most useful event-wide communication tool where everyone could tweet with hash tag #mkcodecamp or #mkdotnet and say what he/she wants to say about the current state and happenings at that moment… In my next blog post I will list the top craziest tweets that were posted at this event… FUTURE OF MKDOT.NET Having such strong community around MKDOT.NET, the future seems very bright. The initial plans are to have sub-groups in several technologies, however all these sub-groups will belong to the MKDOT.NET UG which will be, somehow, the HEAD of these sub-groups. We are doing this to provide better divisions by technologies and organize ourselves better since our community is very big, around 500 members in MKDOT.NET.We will have five sub-groups:- Web User Group (Lead:Hajan Selmani - me)- Mobile User Group (Lead: Filip Kerazovski)- Visual C# User Group (Lead: Vekoslav Stefanovski)- SharePoint User Group (Lead: Darko Milevski)- Dynamics User Group (Lead: Vladimir Senih) SUMMARY Online registered attendees: ~1.200 Event attendees: ~800 Number of members in organization: 40+ Organized by: MKDOT.NET User Group Number of tracks: 5 Number of speakers: 24 Number of sessions: 25 Event official website: http://codecamp.mkdot.net Total number of sponsors: 20 Platinum Sponsors: Microsoft, INETA, Telerik Place held: FON University City and Country: Skopje, Macedonia THANK YOU FOR BEING PART OF THE BEST EVENT IN MACEDONIA, CODE CAMP 2011.

  • Trying to run WCF web service on non-domain VM, Security Errors

    - by NealWalters
    Am I in a Catch-22 situation here? My goal is to take a WCF service that I inherited, and run it on a VM and test it by calling it from my desktop PC. The VM is in a workgroup, and not in the company's domain. Basically, we need more test environments, ideally one per developer (we may have 2 to 4 people that need this). Thus the idea of the VM was that each developer could have his own web server that somewhat matches or real environment (where we actually have two websites, an external/exposed and internal). [Using VS2010 .NET 4.0] In the internal service, each method was decorated with this attribute: [OperationBehavior(Impersonation = ImpersonationOption.Required)] I'm still researching why this was needed. I think it's because a webapp calls the "internal" service, and either a) we need the credentials of the user, or b) we may doing some PrinciplePermission.Demands to see if the user is in a group. My interest is creating some ConsoleTest programs or UnitTest programs. I changed to allowed like this: [OperationBehavior(Impersonation = ImpersonationOption.Allowed)] because I was getting this error in trying to view the .svc in the browser: The contract operation 'EditAccountFamily' requires Windows identity for automatic impersonation. A Windows identity that represents the caller is not provided by binding ('WSHttpBinding','http://tempuri.org/') for contract ('IAdminService','http://tempuri.org/'. I don't get that error with the original bindings look like this: However, I believe I need to turn off this security since the web service is not on the domain. I tend to get these errors in the client: 1) The request for security token could not be satisfied because authentication failed - as an InnerException of "SecurityNegotiation was unhandled". or 2) The caller was not authenticated by the service as an InnerException of "SecurityNegotiation was unhandled". So can I create some configuration of code and web.config that will allow each developer to work on his own VM? Or must I join the VM to the domain? The number of permutations seems near endless. I've started to create a Word.doc that says what to do with each error, but now I'm in the catch-22 where I'm stuck.
