  • Push or Pull to Excel for reporting data

    - by Nathan Fisher
    I am unsure which is the best way to go here. I have a third party Excel 2003 spreadsheet that needs to be filled in on a monthly basis and emailed. Currently it is a manual process and I am in the process of automating the generation of the spreadsheet. I have been throwing around different ideas of how to get the data into the spreadsheet. I have thought of using SSRS to create a report that is in a similar format and get the user to cut and past. Alternatively writing a VBA addin that retrieves that data from a webservice and then adds the data to the spreadsheet. Or using the third party spreadsheet as a template and open it on the server via oledb and adding the data then serving it as a downloadable file. Which is better or are the better solutions out there?

  • should jQuery data be chainable?

    - by pedalpete
    I'm trying to add multiple jQuery data entries to a single element. I suspected that the following would work jQuery('td.person#a'+personId).data('email',thisPerson.email).data('phone',thisPerson.phone); However, I am getting nothing but errors when I do this. jQuery('td.person#a'+personId).data('email',thisPerson.email); jQuery('td.person#a'+personId).data('phone',thisPerson.phone); is there another way to get more than one data entry on an element? Hopefully chained?

  • Data Model Evolution

    - by redleafong
    Hey guys, When writing code I am seeing requirements to change data models (e.g. adding/changing/removing data members from a class). When these data models belong to an interface, it seems difficult to change without breaking the existing client codes. So I am wondering if there is any best practice of designing interfaces/data models in a way to minimize the impact during evolution. The closest thing I can find from google is data contract versioning. But that seems to be a .net specific topic. I am wondering if the same practice applies to the Java world, or there is a different or generic way to deal with data model evolution. Thanks

  • Using protocol buffers for a comprehensive data strategy for Windows Mobile devices

    - by Steve
    I have started reading some of the posts related to protocol buffers. The serialization method seems very appropriate for the transfer of data to and from web servers. Has anyone considered using a method like this to save and retrieve data on the mobile device itself? (i.e. a replacement for a traditional database / orm layer) Where would the data be persisted? How would the data be queried? Would it make sense to store the data in a traditional database (SqlCE or SqlLite) with a few "searchable" columns and then one column for the serialized data? Thoughts? Am I out on a limb here? Thank you!

  • How can I expose a service bus by a wcf service to be consumed by a silverlight client

    - by illdev
    In a Silverlight application, instead of consuming and writing (wcf) wrappers around messages that finally get sent to the bus, I want to send use my message bus as directly as possible. My idea was to expose the service bus directly as a wcf service, or, in other terms, I want to bidirectionally pub/sub over the wire. Has this been done already? Is bi-directionality doable at all? After all, we are (are we restricted to that?) in the http domain? Lots of questions. Some head start would be greatly appreciated! I am in .NET land, with using Rhino Service Bus, but the pattern should apply to different platforms.

  • Estimating the boundary of arbitrarily distributed data

    - by Dave
    I have two dimensional discrete spatial data. I would like to make an approximation of the spatial boundaries of this data so that I can produce a plot with another dataset on top of it. Ideally, this would be an ordered set of (x,y) points that matplotlib can plot with the plt.Polygon() patch. My initial attempt is very inelegant: I place a fine grid over the data, and where data is found in a cell, a square matplotlib patch is created of that cell. The resolution of the boundary thus depends on the sampling frequency of the grid. Here is an example, where the grey region are the cells containing data, black where no data exists. OK, problem solved - why am I still here? Well.... I'd like a more "elegant" solution, or at least one that is faster (ie. I don't want to get on with "real" work, I'd like to have some fun with this!). The best way I can think of is a ray-tracing approach - eg: from xmin to xmax, at y=ymin, check if data boundary crossed in intervals dx y=ymin+dy, do 1 do 1-2, but now sample in y An alternative is defining a centre, and sampling in r-theta space - ie radial spokes in dtheta increments. Both would produce a set of (x,y) points, but then how do I order/link neighbouring points them to create the boundary? A nearest neighbour approach is not appropriate as, for example (to borrow from Geography), an isthmus (think of Panama connecting N&S America) could then close off and isolate regions. This also might not deal very well with the holes seen in the data, which I would like to represent as a different plt.Polygon. The solution perhaps comes from solving an area maximisation problem. For a set of points defining the data limits, what is the maximum contiguous area contained within those points To form the enclosed area, what are the neighbouring points for the nth point? How will the holes be treated in this scheme - is this erring into topology now? Apologies, much of this is me thinking out loud. I'd be grateful for some hints, suggestions or solutions. I suspect this is an oft-studied problem with many solution techniques, but I'm looking for something simple to code and quick to run... I guess everyone is, really! Cheers, David

  • Is the use of a proxy required to consume a WCF service?

    - by Tone
    I have a WCF Service that I want my client to be able to consume from IIS without going through a proxy. The client was consuming asmx service in vbscript using the htc behavior: <div id="oWSInterop" style="behavior:url(webservice.htc)"></div> oWSInterop.useService "http://localhost/WSInteroperability.asmx", "WSInteroperability" Set response = oWSInterop.WSInteroperability.callServiceSync("BuildSingleDoc", 1002, 19499, XMLEncode(sAdditionalDetail)) So basically I just want to make this work with making as few changes as possible on the existing client. Am I forced to use a proxy when consuming a WCF service? I do understand the benefits of a proxy and am not opposed to using it for most other client implementations, but in this case I'm not sure I have the time to deal with it on the client - i just want it to work the way it has been with only the endpoint changing.

  • Entity data field validation and part data submission

    - by pradeeptp
    I have an entity class that has 10 fields. I am using MS Validation Application block to mark all fields as mandatory (IsRequired). I am implementing a securiy feature in which during updation of the data, not all the fields in the entity class will have data. For example a few users can only view 5 fileds while others all 10 fields during updation on GUI I have the following options 1) Bring all the data for all the fields from the DB table and hide the ones not accessible to the users in GUI. I am concerned about the performance because everytime GUI will pull unncessary data. 2) Bring the data (e.g. only 5 fields) that are permissible for access/view by the user on GUI. During submit, validation block will throw exception because all fields are marked as IsRequired and only data for 5 fields are sent back to the server. I want to know if there are any other good approaches to solve problems like this. I am using .NET 3.5 Thanks.

  • How to inject dependencies into a CustomUserNamePasswordValidator in WCF?

    - by Dannerbo
    I'm using a UserNamePasswordValidator in WCF along with Unity for my dependency injection, but since WCF creates the instance of the UserNamePasswordValidator, I cannot inject my container into the class. So how would one go about this? The simplest solution I can think of is to create a static proxy/wrapper class around a static instance of a UnityContainer, which exposes all the same methods... This way, any class can access the container, and I don't need to inject it everywhere. So I could just do UnityContainerWrapper.Resolve() anywhere in code. So basically this solution solves 2 problems for me, I can use it in classes that I'm not creating an instance of, and I can use it anywhere without having to inject the container into a bunch of classes. The only downside I can think of is that I'm now potentially exposing my container to a bunch of classes that wouldn't of had access to the container before. Not really sure if this is even a problem though?

  • WCF net.tcp server disconnects - how to handle properly on client side?

    - by RoastedBattleSquirrel
    I'm stuck with a bit of an annoying problem right now. I've got a Silverlight 4 application (which runs OOB by default). It uses WCF with net.tcp as means of communicating with the server. The client uses a central instance of the wcf client proxy. As long as everything keeps running on the server side, everything's fine. If i kill the server in the middle of everything, i drown in an avalanche of exceptions on the client side (connection lost, channel faulted etc etc). Now i'm looking for a way to handle this in a clean and centralized way (if centralized is possible). The SL app has one central client object sitting in App.cs (public static MyClient Client { get;set;}), which gets initialized on application start. Any idea how to properly handle any connectivity problems on the client object?

  • Reading in gzipped data from S3 in Ruby

    - by Evan Zamir
    My company has data messages (json) stored in gzipped files on Amazon S3. I want to use Ruby to iterate through the files and do some analytics. I started to use the 'aws/s3' gem, and get get each file as an object: #<AWS::S3::S3Object:0x4xxx4760 '/my.company.archive/data/msg/20131030093336.json.gz'> But once I have this object, I do not know how to unzip it or even access the data inside of it.

  • Real-Time Data Streaming to Multiple Clients

    - by AriX
    Hi all, I would like to write an application which will stream data at 2400 baud over the internet from a server to multiple clients. The data will be the same for each client, and it would probably be fine to send it as a UDP stream, since exact data accuracy is not a 100% necessity, as there are checksums built-in to the data format and the data will be sent repeatedly on a loop. What is the best way to do this? I would want to write the server in C, but I don't know how to best multicast this data to the different clients that would be receiving it all over the country. I'm sure this seems like a pretty draconian way to go about my project, as opposed to just using some sort of fetch command, but I'd prefer to do it this way if possible.

  • Can I compose a WCF callback contract out of multiple interfaces?

    - by mafutrct
    Followup question to http://stackoverflow.com/questions/2502930/how-can-i-compose-a-wcf-contract-out-of-multiple-interfaces. I tried to merge multiple callback interfaces in a single interface. This yields an InvalidOperationException claiming that the final interface contains no operations. Technically, this is true, however, the inherited interfaces do contain operations. How can I fix this? Or is this a limitation of WCF? Edit: interface A { [OperationContract]void X(); } interface B { [OperationContract]void Y(); } interface C: A, B {} // this is the public callback contract

  • Data driven charts and graphs from xml to svg

    - by garymlewis
    I asked this question a week ago, but did not do a good job of describing the problem. Here's a second attempt. I'd like to produce data-driven charts, graphs, and other data visualizations, starting with data in an xml database and ending up with the visualizations as SVG. Here's an example from the W3C. It uses Javascript to create a stacked bar chart as SVG from xml. I'd like to do something similar but use a graphics library (or ???) instead of js to handle the construction of axes, labels, titles, data points, etc. My question, then: what are the options that I should consider ... things like Raphael I suppose, but initially I'd like to cast a wide net and look at many different options. My experience is all with static data visualizations using statistics packages like R, but eventually I'd like to create interactive data visualizations with html5/css3/svg. Any help would be much appreciated. Thanks.

  • Does WCF make the consumption of Restful web services trivial?

    - by Steve Weet
    I have an ASP.net application that currently consumes SOAP web services. This platform is targeted at .net 2.0 and I use Visual Studio Professional 2005 to maintain it. I now have a requirement to consume a number of restful web service within the same application. Is the consumption of Restful web services with WCF so trivial, compared to using HttpClient that it is worth the cost and time of upgrading to Visual Studio 2008 and .Net 3.5 framework

  • How to remove thie ".svc" extension in RESTful WCF service?

    - by Morgan Cheng
    In my knowledge, the RESTful WCF still has ".svc" in its URL. For example, if the service interface is like [OperationContract] [WebGet(UriTemplate = "/Value/{value}")] string GetDataStr(string value); The access URI is like "http://machinename/Service.svc/Value/2". In my understanding, part of REST advantage is that it can hide the implementation details. A RESTful URI like "http://machinename/Service/value/2" can be implemented by any RESTful framework, but a "http://machinename/Service.svc/value/2" exposes its implementation is WCF. How can I remove this ".svc" host in the access URI?

  • Tutorial on Consuming a WCF service in ASP.Net web site?

    - by Robert
    I'm attempting to create my first WCF service. I've created the service and now I'm trying to call it from a asp.net (vb) web site and I've tried adding a web reference to it and using the scvutil.exe to consume the service. So far neither have worked. It's not letting me declare the service in my code. If someone could point me to a good tutorial on how to consume a WCF service in an ASP.Net web site that would be great. I've found numorous on how to use them with AJAX or silverlight or windows apps but nothing on using it in just a plain old website.

  • How to limit a request execution time of WCF service?

    - by Kamarey
    Is there something in WCF configuration that defines a timeout for executing a request at service side? E.g. WCF service will stop executing request after some time period. I have a service which make some work depending on client input. In some cases a such call may take too much time. I want to limit the execution time of such requests on service side, not client one using SendTimeout. I know about OperationTimeout property, but it doesn't abort the service request, it just tells a client that the request is timed out.

  • How to Modify Data Security in Fusion Applications

    - by Elie Wazen
    The reference implementation in Fusion Applications is designed with built-in data security on business objects that implement the most common business practices.  For example, the “Sales Representative” job has the following two data security rules implemented on an “Opportunity” to restrict the list of Opportunities that are visible to an Sales Representative: Can view all the Opportunities where they are a member of the Opportunity Team Can view all the Opportunities where they are a resource of a territory in the Opportunity territory team While the above conditions may represent the most common access requirements of an Opportunity, some customers may have additional access constraints. This blog post explains: How to discover the data security implemented in Fusion Applications. How to customize data security Illustrative example. a.) How to discover seeded data security definitions The Security Reference Manuals explain the Function and Data Security implemented on each job role.  Security Reference Manuals are available on Oracle Enterprise Repository for Oracle Fusion Applications. The following is a snap shot of the security documented for the “Sales Representative” Job. The two data security policies define the list of Opportunities a Sales Representative can view. Here is a sample of data security policies on an Opportunity. Business Object Policy Description Policy Store Implementation Opportunity A Sales Representative can view opportunity where they are a territory resource in the opportunity territory team Role: Opportunity Territory Resource Duty Privilege: View Opportunity (Data) Resource: Opportunity A Sales Representative can view opportunity where they are an opportunity sales team member with view, edit, or full access Role: Opportunity Sales Representative Duty Privilege: View Opportunity (Data) Resource: Opportunity Description of Columns Column Name Description Policy Description Explains the data filters that are implemented as a SQL Where Clause in a Data Security Grant Policy Store Implementation Provides the implementation details of the Data Security Grant for this policy. In this example the Opportunities listed for a “Sales Representative” job role are derived from a combination of two grants defined on two separate duty roles at are inherited by the Sales Representative job role. b.) How to customize data security Requirement 1: Opportunities should be viewed only by members of the opportunity team and not by all the members of all the territories on the opportunity. Solution: Remove the role “Opportunity Territory Resource Duty” from the hierarchy of the “Sales Representative” job role. Best Practice: Do not modify the seeded role hierarchy. Create a custom “Sales Representative” job role and build the role hierarchy with the seeded duty roles. Requirement 2: Opportunities must be more restrictive based on a custom attribute that identifies if a Opportunity is confidential or not. Confidential Opportunities must be visible only the owner of the Opportunity. Solution: Modify the (2) data security policy in the above example as follows: A Sales Representative can view opportunity where they are a territory resource in the opportunity territory team and the opportunity is not confidential. Implementation of this policy is more invasive. The seeded SQL where clause of the data security grant on “Opportunity Territory Resource Duty” has to be modified and the condition that checks for the confidential flag must be added. Best Practice: Do not modify the seeded grant. Create a new grant with the modified condition. End Date the seeded grant. c.) Illustrative Example (Implementing Requirement 2) A data security policy contains the following components: Role Object Instance Set Action Of the above four components, the Role and Instance Set are the only components that are customizable. Object and Actions for that object are seed data and cannot be modified. To customize a seeded policy, “A Sales Representative can view opportunity where they are a territory resource in the opportunity territory team”, Find the seeded policy Identify the Role, Object, Instance Set and Action components of the policy Create a new custom instance set based on the seeded instance set. End Date the seeded policies Create a new data security policy with custom instance set c-1: Find the seeded policy Step 1: 1. Find the Role 2. Open 3. Find Policies Step 2: Click on the Data Security Tab Sort by “Resource Name” Find all the policies with the “Condition” as “where they are a territory resource in the opportunity territory team” In this example, we can see there are 5 policies for “Opportunity Territory Resource Duty” on Opportunity object. Step 3: Now that we know the policy details, we need to create new instance set with the custom condition. All instance sets are linked to the object. Find the object using global search option. Open it and click on “condition” tab Sort by Display name Find the Instance set Edit the instance set and copy the “SQL Predicate” to a notepad. Create a new instance set with the modified SQL Predicate from above by clicking on the icon as shown below. Step 4: End date the seeded data security policies on the duty role and create new policies with your custom instance set. Repeat the navigation in step Edit each of the 5 policies and end date them 3. Create new custom policies with the same information as the seeded policies in the “General Information”, “Roles” and “Action” tabs. 4. In the “Rules” tab, please pick the new instance set that was created in Step 3.

  • Workaround for datadude deployment bug - NullReferenceException

    - by jamiet
    I have come across a bug in Visual Studio 2010 Database Projects (aka datadude aka DPro aka Visual Studio Database Development Tools aka Visual Studio Team Edition for Database Professionals aka Juneau aka SQL Server Data Tools) that other people may encounter so, for the purposes of googling, I'm writing this blog post about it. Through my own googling I discovered that a Connect bug had already been raised about it (VS2010 Database project deploy - “SqlDeployTask” task failed unexpectedly, NullReferenceException), and coincidentally enough it was raised by my former colleague Tom Hunter (whom I have mentioned here before as the superhuman Tom Hunter) although it has not (at this time) received a reply from Microsoft. Tom provided a repro, namely that this syntactically valid function definition: CREATE FUNCTION [dbo].[Function1]()RETURNS TABLEASRETURN (    WITH cte AS (    SELECT 1 AS [c1]    FROM [$(Database3)].[dbo].[Table1]   )   SELECT 1 AS [c1]   FROM cte) would produce this nasty unhelpful error upon deployment: C:\Program Files

circumstances that need to be met for this error to occur: The object being deployed is an inline function  (may also exist for multistatement and scalar functions - I haven't tested that) That object includes SQLCMD variable references The object has already been deployed successfully Just to reiterate that last bullet point, the error does not occur when you deploy the function for the first time, only on the subsequent deployment.   Luckily I have a direct line into a guy on the development team so I fired off an email on Friday evening and today (Monday) I received a reply back telling me that there is a simple fix, one simply has to remove the parentheses that wrap the SQL statement. So, in the case of Tom's repro, the function definition simpy has to be changed to: CREATE FUNCTION [dbo].[Function1]()RETURNS TABLEASRETURN --(    WITH cte AS (    SELECT 1 AS [c1]    FROM [$(Database3)].[dbo].[Table1]   )   SELECT 1 AS [c1]   FROM cte--) I have commented out the offending parentheses rather than removing them just to emphasize the point. Thereafter the function will deploy fine. I tested this out on my own project this morning and can confirm that this fix does indeed work.   I have been told that the bug CAN be reproduced in the Release Candidate (RC) 0 build of SQL Server Data Tools in SQL Server 2010 so am hoping that a fix makes it in for the Release-To-Manufacturing (RTM) build. Hope this helps @jamiet
