• PCI Encryption Key Management

  - by Unicorn Bob

  (Full disclosure: I'm already an active participant here and at StackOverflow, but for reasons that should hopefully be obvious, I'm choosing to ask this particular question anonymously). I currently work for a small software shop that produces software that's sold commercially to manage small- to mid-size business in a couple of fairly specialized industries. Because these industries are customer-facing, a large portion of the software is related to storing and managing customer information. In particular, the storage (and securing) of customer credit card information. With that, of course, comes PCI compliance. To make a long story short, I'm left with a couple of questions about why certain things were done the way they were, and I'm unfortunately without much of a resource at the moment. This is a very small shop (I report directly to the owner, as does the only other full-time employee), and the owner doesn't have an answer to these questions, and the previous developer is...err...unavailable. Issue 1: Periodic Re-encryption As of now, the software prompts the user to do a wholesale re-encryption of all of the sensitive information in the database (basically credit card numbers and user passwords) if either of these conditions is true: There are any NON-encrypted pieces of sensitive information in the database (added through a manual database statement instead of through the business object, for example). This should not happen during the ordinary use of the software. The current key has been in use for more than a particular period of time. I believe it's 12 months, but I'm not certain of that. The point here is that the key "expires". This is my first foray into commercial solution development that deals with PCI, so I am unfortunately uneducated on the practices involved. Is there some aspect of PCI compliance that mandates (or even just strongly recommends) periodic key updating? This isn't a huge issue for me other than I don't currently have a good explanation to give to end users if they ask why they are being prompted to run it. Question 1: Is the concept of key expiration standard, and, if so, is that simply industry-standard or an element of PCI? Issue 2: Key Storage Here's my real issue...the encryption key is stored in the database, just obfuscated. The key is padded on the left and right with a few garbage bytes and some bits are twiddled, but fundamentally there's nothing stopping an enterprising person from examining our (dotfuscated) code, determining the pattern used to turn the stored key into the real key, then using that key to run amok. This seems like a horrible practice to me, but I want to make sure that this isn't just one of those "grin and bear it" practices that people in this industry have taken to. I have developed an alternative approach that would prevent such an attack, but I'm just looking for a sanity check here. Question 2: Is this method of key storage--namely storing the key in the database using an obfuscation method that exists in client code--normal or crazy? Believe me, I know that free advice is worth every penny that I've paid for it, nobody here is an attorney (or at least isn't offering legal advice), caveat emptor, etc. etc., but I'm looking for any input that you all can provide. Thank you in advance!

• College Ratings via the Federal Government

  - by user9147039

  A few weeks back you might remember news about a higher education rating system proposal from the Obama administration. As I've discussed previously, political and stakeholder pressures to improve outcomes and increase transparency are stronger than ever before. The executive branch proposal is intended to make progress in this area. Quoting from the proposal itself, "The ratings will be based upon such measures as: Access, such as percentage of students receiving Pell grants; Affordability, such as average tuition, scholarships, and loan debt; and Outcomes, such as graduation and transfer rates, graduate earnings, and advanced degrees of college graduates.” This is going to be quite complex, to say the least. Most notably, higher ed is not monolithic. From community and other 2-year colleges, to small private 4-year, to professional schools, to large public research institutions…the many walks of higher ed life are, well, many. Designing a ratings system that doesn't wind up with lots of unintended consequences and collateral damage will be difficult. At best you would end up potentially tarnishing the reputation of certain institutions that were actually performing well against the metrics and outcome measures that make sense in their "context" of education. At worst you could spend a lot of time and resources designing a system that would lose credibility with its "customers". A lot of institutions I work with already have in place systems like the one described above. They are tracking completion rates, completion timeframes, transfers to other institutions, job placement, and salary information. As I talk to these institutions there are several constants worth noting: • Deciding on which metrics to measure is complicated. While employment and salary data are relatively easy to track, qualitative measures are more difficult. How do you quantify the benefit to someone who studies in one field that may not compensate him or her as well as another field but that provides huge personal fulfillment and reward is a difficult measure to quantify? • The data is available but the systems to transform the data into actual information that can be used in meaningful ways are not. Too often in higher ed information is siloed. As such, much of the data that need to be a part of a comprehensive system sit in multiple organizations, oftentimes outside the reach of core IT. • Politics and culture are big barriers. One of the areas that my team and I spend a lot of time talking about with higher ed institutions all over the world is the imperative to optimize for student success. This, like the tracking of the students’ achievement after graduation, requires a level or organizational capacity that does not currently exist. The primary barrier is the culture of "data islands" in higher ed, and the need for leadership to drive out the divisions between departments, schools, colleges, etc. and institute academy-wide analytics and data stewardship initiatives that will enable student success. • Data quality is a very big issue. So many disparate systems exist (some on premise, some "in the cloud") that keep data about "persons" using different means to identify them. Establishing a single source of truth about an individual and his or her data is difficult without some type of data quality policy and tools. Good tools actually exist but are seldom leveraged. Don't misunderstand - I think it's a great idea to drive additional transparency and accountability into the system of higher education. And not just at home, but globally. Students and parents need access to key data to make informed, responsible choices. The tools exist to not only enable this kind of information to be shared but to capture the very metrics stakeholders care most about and in a way that makes sense in the context of a given institution's "place" in the overall higher ed panoply.

• Cloud Fact for Business Managers #3: Where You Data Is, and Who Has Access to It Might Surprise You

  - by yaldahhakim

  Written by: David Krauss While data security and operational risk conversations usually happen around the desk of a CCO/CSO (chief compliance and/or security officer), or perhaps the CFO, since business managers are now selecting cloud providers, they need to be able to at least ask some high-level questions on the topic of risk and compliance.  While the report found that 76% of adopters were motivated to adopt cloud apps because of quick access to software, most of these managers found that after they made a purchase decision their access to exciting new capabilities in the cloud could be hindered due to performance and scalability constraints put forth  by their cloud provider.  If you are going to let your business consume their mission critical business applications as a service, then it’s important to understand who is providing those cloud services and what kind of performance you are going to get.  Different types of departments, companies and industries will all have unique requirements so it’s key to take this also into consideration.   Nothing puts a CEO in a bad mood like a public data breach or finding out the company lost money when customers couldn’t buy a product or service because your cloud service provider had a problem.  With 42% of business managers having seen a data security breach in their department associated directly with the use of cloud applications, this is happening more than you think.   We’ve talked about the importance of being able to avoid information silos through a unified cloud approach and platform.  This is also important when keeping your data safe and secure, and a key conversation to have with your cloud provider.  Your customers want to know that their information is protected when they do business with you, just like you want your own company information protected.   This is really hard to do when each line of business is running different cloud application services managed by different cloud providers, all with different processes and controls.   It only adds to the complexity, and the more complex, the more risky and the chance that something will go wrong. What about compliance? Depending on the cloud provider, it can be difficult at best to understand who has access to your data, and were your data is actually stored.  Add to this multiple cloud providers spanning multiple departments and it becomes very problematic when trying to comply with certain industry and country data security regulations.  With 73% of business managers complaining that having cloud data handled externally by one or more cloud vendors makes it hard for their department to be compliant, this is a big time suck for executives and it puts the organization at risk. Is There A Complete, Integrated, Modern Cloud Out there for Business Executives?If you are a business manager looking to drive faster innovation for your business and want a cloud application that your CIO would approve of, I would encourage you take a look at Oracle Cloud.  It’s everything you want from a SaaS based application, but without compromising on functionality and other modern capabilities like embedded business intelligence, social relationship management (for your entire business), and advanced mobile.  And because Oracle Cloud is built and managed by Oracle, you can be confident that your cloud application services are enterprise-grade.  Over 25 Million users and 10 thousands companies around the globe rely on Oracle Cloud application services everyday – maybe your business should too.  For more information, visit cloud.oracle.com.

• Building Enterprise Smartphone App &ndash; Part 1: Why Build Smart Phone Apps

  - by Tim Murphy

  This is part 1 in a series of post based on a talk I gave recently at the Chicago Information Technology Architects Group.  Feel free to leave feedback. Intro Most of us already carry smartphones. We play games on them. We keep up with what is going on with our friends and our favorite teams. We take pictures of our kids at their events. But the question is if that is all they are good for. Many companies have aspects of their business that lend themselves to being performed by mobile devices. Some of them lean toward larger device such as tablets, but many can be executed on smartphones. This and the following articles will discuss some of the possible applications of smartphone technology for businesses, the platforms that are available and the considerations you need to make when building them. I'll take a look at some specific scenarios and wrap up with a couple of capabilities that are just emerging that can be used in the future. Why Build Enterprise Smartphone Applications So what are some of the ways that you can leverage smartphone technology to gain efficiency in your business or a clients business. There are a few major areas that I have seen mobile platforms being an advantage to. Your mobile sales force is a key candidate for leveraging smartphone apps.  They can visit clients in their retail location and place orders on site. It is a more personal approach which can gain you customer loyalty.  A sales person may also gather information about the way a client does business or who their target market is. This allows them you to focus marketing information or build customized support for your customer. You may also have need to track physical inventory in a store. This is something that has historically been done with laser scanners, but with the camera capabilities in today's phones and tablets it is possible to use more general multi-purpose devices.  This can save costs on both hardware and telecommunication contracts. Delivery verification is another area that historically has been the domain of specialized devices but can now be accomplished with smartphones.  This also reduces costs because it is also used for communicating with the driver and other operations.  Add to that the navigation capability of smartphones and you can see how the return on investment increases. Executives are always on the go. They spend most of their time in meetings and yet they need access to decision making information at their finger tips. With a smartphone app they can get alerts when major sales are closed or critical accounting process are completed that may need their attention. They can also answer questions by instantly pulling up BI reports. I have often heard operations support people say that they need things like VPN and RDP from their phones. If they can also have notifications of outages or critical support requests they can be react to situations without needing to be tied to their desks. These are all valid reasons to need smartphone applications.  In the next installment I will discuss platforms and features. del.icio.us Tags: Smartphones,Enterprise Smartphone Apps,Architecture

• Upgrade to Azure 2.2 SDK is causing roles to fail

  - by Jon Leach

  I have 3 worker roles and a web role in my project and I upgraded it to the new 2.2 SDK (required in VS2013). Ever since the upgrade, all of the worker roles are failing and they instantly recycle as soon as they're started. When the roles start, I'm getting these messages: Microsoft.WindowsAzure.ServiceRuntime Information: 200 : Role entrypoint . CALLING OnStart() Microsoft.WindowsAzure.ServiceRuntime Information: 202 : Role entrypoint . COMPLETED OnStart() The thread 0x441c has exited with code 259 (0x103). Microsoft.WindowsAzure.ServiceRuntime Information: 203 : Role entrypoint . CALLING Run() Microsoft.WindowsAzure.ServiceRuntime Warning: 204 : Role entrypoint . COMPLETED Run() ==> ROLE RECYCLING INITIATED Microsoft.WindowsAzure.ServiceRuntime Information: 503 : Role instance recycling is starting The thread 0x2684 has exited with code 259 (0x103) Two things draw my attention: I've started to see a bunch of errors "Cannot find or open the PDB file." But I don't know that this is directly relevant. I'm using VS 2013 and while the project lists the SDK as 2.2, the references within the roles are the 2.1 versions. Do I need to upgrade the components? Why wouldn't the project upgrade these automatically when I pulled the project into VS as it only support 2.2? Any thoughts on how to attach this are appreciated.

How can I avoid this?

• Custom Installer class , rollback method never called.

  - by yossi1981

  Hi guys. I am having an installer class , Here is a snippet: [RunInstaller(true)] public partial class ServerWrapInstaller : Installer { public override void Install(IDictionary stateSaver) { EventLog.WriteEntry("Installer", "Install", EventLogEntryType.Information); base.Install(stateSaver); } public override void Commit(IDictionary savedState) { EventLog.WriteEntry("Installer", "Commit", EventLogEntryType.Information); base.Commit(savedState); } public override void Rollback(IDictionary savedState) { EventLog.WriteEntry("Installer", "Rollback", EventLogEntryType.Information); base.Rollback(savedState); } public override void Uninstall(IDictionary savedState) { EventLog.WriteEntry("Installer", "UnInstall", EventLogEntryType.Information); base.Uninstall(savedState); } } Now i start the installation in full GUI mode and then click the "Cancel" button in the middle of the process causing the installation to roll back. The problem is that the RollBack method is not called. I don't see the expected entry in the event log. I want to mention that if i let the installation to complete , I do see the "Install" message in the event log and If i then uninstall , I see the "uninstall" message in the event log. But if stop the installtion process in the middle , by pressing the "cancel" button , I do see the progress bar going backward , but the rollback method is not called. what am I doing wrong ? thanks in advance for any help. Edit: Providing more details... The installer is an MSI package. The package is built in vs2009 using a setup project. The installer class is used as a custom action by the setup project. Since this is a MSI Package I have an option to run it in silent mode or in user-interactive more . When I wrote "Full GUI mode" , I ment User-Interactive mode.

• Working with partial views

  - by MrW

  Hi. I'm trying to create a page that contains a grid and searching. The issue is that I want to have a partial view for the grid and one for the searching. If doing a search, this should render the grid partial view with the new information. At the moment I need information, such as what column I'm sorting by and so on, from the grid (currently stored in viewdata), in order to do the search as I want to keep those settings. This information is only available in the grid partial though. What's the best approach of this to make it neat and nice in the code, but not a mess to work with? Where can I store information that I need in the other partial view? Partial View 1; <table> <%= Html.CreateGrid(Model, "Grid", "Grid", (int)ViewData["SortColumn"], (bool)ViewData["SortedASC"])%> </table> Partial View 2; <div class="searchControl"> <input type="text" class="SearchBox" href="<%= Url.Action("Grid", "Grid", new {page = 1, columnToSortBy=/* would like to access viewdata from partial view 1 here. */, sortASC = /* would like to access viewdata from partial view 1 here. */ } ) %>" /> <input type="submit" value="Search" class="SearchButton" /> </div> I know I might take the completely wrong approach on this, so feel free to point me in the right one! Thanks!

• Visual studio 2010 setup project problem.

  - by Guru

  Hi there, I've made an application that uses .NET framework 3.5 SP1 and SQL Server 2008 Express. Application is fine and now i'm going to to make a setup project for this. When I first build my setup it was fine as all the prerequisites were not included in setup. But I want my setup to install .NET 3.5 SP1 and SQL SERVER 2008 Express also. So for this I've changed the options in setup project's properties from "Download prerequisites from following location" to "Download prerequisites from the same location as my application". In addition to that I've also checked the options above like .NET 3.5 SP1 and SQL Server 2008 Express etc. After doing all this I build my project again. This time I'm Getting 57 Errors. Error 1 The install location for prerequisites has not been set to 'component vendor's web site' and the file 'DotNetFX35SP1\dotNetFX20\aspnet.msp' in item '.NET Framework 3.5 SP1' can not be located on disk.

• Using PHP cURL with an HTTP Debugging Proxy

  - by Kane

  I'm using the app "Fiddler" to debug a GET attempt to a website via PHP cURL. In order to see the cURL traffic I had to specify that the cURL connection use the Fiddler proxy (see code below). $ch = curl_init(); curl_setopt($ch, CURLOPT_HTTPPROXYTUNNEL, 1); curl_setopt($ch, CURLOPT_PROXY, '127.0.0.1:8888'); curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 5); curl_setopt($ch, CURLOPT_TIMEOUT, 10); curl_setopt($ch, CURLOPT_HEADERFUNCTION, 'read_header'); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch, CURLOPT_USERAGENT, $user_agent); curl_setopt($ch, CURLOPT_REFERER, "http://domain.com"); curl_setopt($ch, CURLOPT_HTTPHEADER, $headers); curl_setopt($ch, CURLOPT_COOKIEJAR, "my_cookies.txt"); curl_setopt($ch, CURLOPT_COOKIEFILE, "my_cookies.txt"); curl_setopt($ch, CURLOPT_URL, "http://domain.com"); $response = curl_exec($ch); But the problem is that in Fiddler I can only see this: Request (domain.com is just an alias): CONNECT domain.com:80 HTTP/1.1 Response: HTTP/1.1 200 Blind-Connection Established If I manually load the website in a browser Fiddler gives me WAY more information. I can see the cookies, the header information, and what I'm receiving via the GET. Any ideas why Fiddler can't see more useful information from PHP cURL? Edit: I tried turning on the "Enable HTTPS Decryption" option inside Tools / Fiddler Options / HTTPS (which I'm not sure why I'd need to use as I didn't tell cURL to use HTTPS). Unfortunately, by changing this setting I now get a Response of: HTTP/1.1 502 Connection failed Edit: If it helps, the app "Charles" shows me WAY more information than Fiddler, but I really want to figure out Fiddler since I like it better.

• IIS, Web services, Time out error

  - by Eduard

  Hello, We’ve got problem with ASP.NET web application that uses web services of other system. I’ll describe our system architecture: we have web application and Windows services that uses the same web services. - Windows service works all the time and sends information to these web services once an hour. - Web application is designed for users to send the same information in manual behavior. The problem is when user sometimes tries to send information in manual behavior in the web application, .NET throws exception „The operation has timed out” (web?). At that time Windows service successfully sends all necessary information to these web services. IT stuff that supports these web services asserts that there was no any request from our web application at that time. Then we have restarted IIS (iisreset) and everything has started to work fine. This situation repeats all the time. There is no anti-virus or firewall on the server. My suggestion is that there is something wrong with IIS, patches, configuration or whatever? The only specific thing is that there are requests that can least 2 minutes (web service response wait time). We tried to reproduce this situation on our local test servers, but everything works fine. OS: Windows Server 2003 R2 .NET: 3.5

• mysql database normalization question

  - by Chocho

  here is my 3 tables: table 1 -- stores user information and it has unique data table 2 -- stores place category such as, toronto, ny, london, etc hence this is is also unique table 3 -- has duplicate information. it stores all the places a user have been. the 3 tables are linked or joined by these ids: table 1 has an "table1_id" table 2 has an "table2_id" and "place_name" table 3 has an "table3_id", "table1_id", "place_name" i have an interface where an admin sees all users. beside a user is "edit" button. clicking on that edit button allows you to edit a specific user in a form fields which has a multiple drop down box for "places". if an admin edits a user and add 1 "places" for the user, i insert that information using php. if the admin decides to deselect that 1 "places" do i delete it or mark it as on and off? how about if the admin decides to select 2 "places" for the user; change the first "places" and add an additional "places". will my table just keep growing and will i have just redundant information? thanks.

• how to queue function behind ajax request

  - by user1052335

  What I'm asking is conceptual rather than why my code doesn't work. I'm trying to make a web app that displays content fetched from a database in a sequence, one at a time, and then waits for a response from the user before continuing to the next one. I'm working with javascript on the client side with the JQuery library and php on the server side. In theory, there's time while waiting for the user's input to fetch information from the server using an AJAX request and have it ready for the use by the time he clicks the button, but there's also a chance that such an AJAX request hasn't completed when he clicks the button. So I need something like pseudocode: display current information fetch next data point from the server in the background onUserInput { if ( ajax request complete) { present the information fetched in this request } else if (ajax request not complete) { wait for ajax request complete present information to user } My question is this: how does one implement this " else if (ajax request not complete) { wait for ajax request complete " part. I'm currently using JQuery for my AJAX needs. I'm somewhat new to working with AJAX, and I did search around, but I didn't find anything that seemed on point. I don't know what tools I should use for this. Some kind of queue maybe? I don't need to be spoon fed. I just need to know how this is done, using what tools or if my desired outcome would be accomplished in some other way entirely. Thanks.

• What's the best BDD framework for working with ASP.NET MVC 2 + C# 4?

  - by Soul_Master

  I just heard about BDD when I watch video of Scott Guthrie in Sweden. One of listener asked question to Scott about How VS2010 and ASP.NET MVC do to support BDD. After that, I search about BDD (Behavior Driven Development) that focus on specification more than unit testing when compares with TDD (Test Driven Development). I found some framework that work with Ruby and Java. But I do not any famous framework for .NET. Please suggest me about BDD framework and summary PROs/CONs of it. PS. Suggested BDD framework must work great on .NET 4, C# 4.0 and ASP.NET MVC 2. Thanks,

• How do I implement page authorizaton in ASP.NET using a SQL store instead of web.config?

  - by drachenstern

  For instance, the way we're doing it now is like thus: (in the web.config) <location path="somePath"> <system.web> <authorization> <allow roles="approvedRoles"/> <deny users="*"/> </authorization> </system.web> </location> And what I would like to do instead is to store this information in SQL somewhere so that we can manipulate the information more easily. But we want to keep the same functionality that having the information in web.config provides, just like we can use a SqlRoleProvider instead of hardcoding roles in the app. So in other words, if a user currently tries to goto "somePath" and they're not a member of "approvedRoles" then they get redirected back to default.aspx, and if they are a member of "approvedRoles" then they get the page. I want to do the same thing, but without using web.config as the authorization mechanism. So what I'm NOT asking is how do I go about defining roles, or how do I handle logging in to the database, but specifically how do I store the above information in SQL instead of web.config. Actually, I'll take "anywhere but web.config" for now. Any ideas? Is this possible using a "Provider" class? I'm just looking for pointers on what to inherit and maybe some technet documentation. In this regard my googlefoo is lacking since I don't really know where to point. Am I really only looking for AzMan? Is this location-authorization-via-SQL already defined in the default aspnetdb somewhere and I'm missing it? For that matter, has this question already been asked on SO and I've missed it? What would you google?

• RIA Services and Shared domainlogic??

  - by NPehrsson

  I'm kind of disappointed at Ria Services. I like to work in a domain driven design way, so for example if I'm working with an invoicing system I have an object invoice which will have all methods on it to for example calculate total price from its invoice rows. public decimal Amount { get {return Entries.Sum(x => x.Amount);} } I like to have methods to add a new row to validate in data. public void AddInvoiceRow(Article article, decimal quantity) This is functionality I need on both client and server side. Have I missed something big or is RIA Services not for me? (In the whole, I don't like Silverlight restrictions at all, I mean that we need get; set on every data field we want to transfer for example some fields are not public at all in domain driven design but the technique Silverlight offers forcing us to do bad coding.)

• How to set QNetworkReply properties to get correct NCBI pages?

  - by Claire Huang

  I try to get this following url using the downloadURL function: http://www.ncbi.nlm.nih.gov/nuccore/27884304 But the data is not as what we can see through the browser. Now I know it's because that I need to give the correct information such as browser, how can I know what kind of information I need to set, and how can I set it? (By setHeader function??) In VC++, we can use CInternetSession and CHttpConnection Object to get the correct information without setting any other detail information, is there any similar way in Qt or other cross-platform C++ network lib?? (Yes, I need the the cross-platform property.) QNetworkReply::NetworkError downloadURL(const QUrl &url, QByteArray &data) { QNetworkAccessManager manager; QNetworkRequest request(url); request.setHeader(QNetworkRequest::ContentTypeHeader ,"Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9.1.7) Gecko/20091221 Firefox/3.5.7 (.NET CLR 3.5.30729)"); QNetworkReply *reply = manager.get(request); QEventLoop loop; QObject::connect(reply, SIGNAL(finished()), &loop, SLOT(quit())); loop.exec(); QVariant statusCodeV = reply->attribute(QNetworkRequest::RedirectionTargetAttribute); QUrl redirectTo = statusCodeV.toUrl(); if (!redirectTo.isEmpty()) { if (redirectTo.host().isEmpty()) { const QByteArray newaddr = ("http://"+url.host()+redirectTo.encodedPath()).toAscii(); redirectTo.setEncodedUrl(newaddr); redirectTo.setHost(url.host()); } return (downloadURL(redirectTo, data)); } if (reply->error() != QNetworkReply::NoError) { return reply->error(); } data = reply->readAll(); delete reply; return QNetworkReply::NoError; }

• Updating a local sqlite db that is used for local metadata & caching from an service?

  - by Pharaun

  I've searched through the site and haven't found a question/answer that quite answer my question, the closest one I found was: Syncing objects between two disparate systems best approach. Anyway to begun, because there is no RSS feeds available, I'm screen scrapping a webpage, hence it does a fetch then it goes through the webpage to scrap out all of the information that I'm interested in and dumps that information into a sqlite database so that I can query the information at my leisure without doing repeat fetching from the website. However I'm also storing various metadata on the data itself that is stored in the sqlite db, such as: have I looked at the data, is the data new/old, bookmark to a chunk of data (Think of it as a collection of unrelated data, and the bookmark is just a pointer to where I am in processing/reading of the said data). So right now my current problem is trying to figure out how to update the local sqlite database with new data and/or changed data from the website in a manner that is effective and straightforward. Here's my current idea: Download the page itself Create a temporary table for the parsed data to go into Do a comparison between the official and the temporary table and copy updates and/or new information to the official table This process seems kind of complicated because I would have to figure out how to determine if the data in the temporary table is new, updated, or unchanged. So I am wondering if there isn't a better approach or if anyone has any suggestion on how to architecture/structure such system?

• How to get notified about changes on SharePoint groups.

  - by Flo

  Hi, I'm actual looking for a way to get notified about any changes on a SharePoint group. First I though I would be able to this by attaching a event handler to some kind of group list. But unfortunately there are no such list representing SharePoint groups. My second attempt was to bind a event handler to the content type SharePointGroup but this didn't work either. So are there any other options to get notified about events on a SharePoint group? Bye, Flo EDIT: Thanks for the reply so far. I forgot to mention that I've already googled and read about the user information list. Sorry. First I found a forum entry where they post the relative URL to the user information list (_catalogs/users/simple.aspx). When I'm using this link to see the list,it only contains users and no groups. I don't know but perhaps this link does some filtering on the list. The other information I found about in several blog and forum posts was that a event handler attached to the user information list are not fired up on an events. I have to admit after reading that it doesn't work so many times and even on MSDN (http://msdn.microsoft.com/en-us/library/aa979520.aspx), I didn't try it on my own. The problem attaching the event handler to the content type wasn't the attaching thing, the handler simply didn't get fired when I for example changed a group name or deleted a user from the group. I don't have an idea why the handler doesn't get called I pretty sure I implemented the right methods and attached them to the right events. Any other suggestions how to get informed about changes on SharePoint groups?
