    Originally posted on: http://geekswithblogs.net/ilich/archive/2013/11/04/sql-server-reporting-services-report-viewer-wrapper-for-asp.net-mvc.aspxSQL Server Reporting Services is rich and popular reporting solution that you have free with SQL Server. It is widely used in the industry: from small family businesses running on SQL Server 2008/2012 express to huge corporations with SQL Server clusters. There is one issue with the solution. Microsoft has not release SSRS viewer for ASP.NET MVC yet. That is why people usually mixing modern ASP.NET MVC enterprise applications with ASP.NET Web Forms pages to view report. Today I released ASP.NET MVC HTML helper which renders a basic ASP.NET Web Forms ReportViewer control inside an iframe. You can get it from NuGet. The package name is MvcReportViewer. The documentation and source code are available on GitHub under MIT license: https://github.com/ilich/MvcReportViewer. Bug reports, patches and other contributions are welcome!

  • Assistance in setting up new APC Smart-UPS RT on a new VMware enviroment

    - by user38085
    I'm new to the realm of setting up a APC Smart-UPS RT 8000VA UPS with a management network card (AP9618). The project calls for the upgrade of the firmware for the network card to the newest and greatest. It also calls for the Powerchute Business Software to be installed with notifications setup per email for temperature, shutdown, and battery low. I know I'll have to use the serial cable to flash the firmware and install the software on one server 2003 box. Also on that server I'll have to install the software and setup the GUI (IP address) interface. Whats confusing the most is the whole process, and steps to use without taking down the network, which would be very bad. In flashing the firmware does it take down the UPS? Do i have to run BOOTP commands to setup the network card? Also no agents will be used on any of the VWware OS's and no SNMP trap will be used.

  • SQL Azure Security: DoS

    - by Herve Roggero
    Since I decided to understand in more depth how SQL Azure works I started to dig into its performance characteristics. So I decided to write an application that allows me to put SQL Azure to the test and compare results with a local SQL Server database. One of the options I added is the ability to issue the same command on multiple threads to get certain performance metrics. That's when I stumbled on an interesting security feature of SQL Azure: its Denial of Service (DoS) detection engine. What this security feature does is that it performs a check on the number of connections being established, and if the rate of connection is too high, SQL Azure blocks all communication from that machine. I am still trying to learn more about this specific feature, but it appears that going to the SQL Azure portal and testing the connection from the portal "resets" the feature and you are allowed to connect again... until you reach the login threashold. In the specific test I was performing, all the logins were successful. I haven't tried to login with an invalid account or password... that will be for next time. On my Linked In group (SQL Server and SQL Azure Security: http://www.linkedin.com/groups?gid=2569994&trk=hb_side_g) Chip Andrews (www.sqlsecurity.com) pointed out that this feature in itself could present an internal threat. In theory, a rogue application could be issuing many login requests from a NATed network, which could potentially prevent any production system from connecting to SQL Azure within the same network. My initial response was that this could indeed be the case. However, while the TCP protocol contains the latest NATed IP address of a machine (which masks the origin of the machine making the SQL request), the TDS protocol itself contains the IP Address of the machine making the initial request; so technically there would be a way for SQL Azure to block only the internal IP address making the rogue requests.  So this warrants further investigation... stay tuned...

  • New SQLOS features in SQL Server 2012

    - by SQLOS Team
    Here's a quick summary of SQLOS feature enhancements going into SQL Server 2012. Most of these are already in the CTP3 pre-release, except for the Resource Governor enhancements which will be in the release candidate. We've blogged about a couple of these items before. I plan to add detail. Let me know which ones you'd like to see more on: - Memory Manager Redesign: Predictable sizing and governing SQL memory consumption: sp_configure ‘max server memory’ now limits all memory committed by SQL ServerResource Governor governs all SQL memory consumption (other than special cases like buffer pool) Improved scalability of complex queries and operations that make >8K allocations Improved CPU and NUMA locality for memory accesses Single memory manager that handles page allocations of all sizes Consistent Out-of-memory handling & management across different internal components - Optimized Memory Broker for Column Store indexes (Project Apollo) - Resource Governor Support larger scale multi-tenancy by increasing Max. number of resource pools20 -> 64 [for 64-bit] Enable predictable chargeback and isolation by adding a hard cap on CPU usage Enable vertical isolation of machine resources Resource pools can be affinitized to individual or groups of schedulers or to NUMA nodes New DMV for resource pool affinity  - CLR 4 support, adds .NET Framework 4 advantages - sp_server_dianostics Captures diagnostic data and health information about SQL Server to detect potential failures Analyze internal system state Reliable when nothing else is working   - New SQLOS DMVs (in 2008 R2SP1) SQL Server related configuration - New DMVsys.dm_server_services OS related resource configurationNew DMVssys.dm_os_volume_statssys.dm_os_windows_infosys.dm_server_registry XEvents for SQL and OS related Perfmon counters Extend sys.dm_os_sys_info See previous blog posts here and here. - Scale / Mission critical Increased scalability: Support Windows 8 max memory and logical processorsDynamic Memory support in Standard Edition - Hot-Add Memory enabled when virtualized - Various Tier1 Performance Improvements, including reduced instructions for superlatches.

  • Switch or a Dictionary when assigning to new object

    - by KChaloux
    Recently, I've come to prefer mapping 1-1 relationships using Dictionaries instead of Switch statements. I find it to be a little faster to write and easier to mentally process. Unfortunately, when mapping to a new instance of an object, I don't want to define it like this: var fooDict = new Dictionary<int, IBigObject>() { { 0, new Foo() }, // Creates an instance of Foo { 1, new Bar() }, // Creates an instance of Bar { 2, new Baz() } // Creates an instance of Baz } var quux = fooDict[0]; // quux references Foo Given that construct, I've wasted CPU cycles and memory creating 3 objects, doing whatever their constructors might contain, and only ended up using one of them. I also believe that mapping other objects to fooDict[0] in this case will cause them to reference the same thing, rather than creating a new instance of Foo as intended. A solution would be to use a lambda instead: var fooDict = new Dictionary<int, Func<IBigObject>>() { { 0, () => new Foo() }, // Returns a new instance of Foo when invoked { 1, () => new Bar() }, // Ditto Bar { 2, () => new Baz() } // Ditto Baz } var quux = fooDict[0](); // equivalent to saying 'var quux = new Foo();' Is this getting to a point where it's too confusing? It's easy to miss that () on the end. Or is mapping to a function/expression a fairly common practice? The alternative would be to use a switch: IBigObject quux; switch(someInt) { case 0: quux = new Foo(); break; case 1: quux = new Bar(); break; case 2: quux = new Baz(); break; } Which invocation is more acceptable? Dictionary, for faster lookups and fewer keywords (case and break) Switch: More commonly found in code, doesn't require the use of a Func< object for indirection.

  • Hiring New IT Employees versus Promoting Internally for IT Positions

    Recently I was asked my opinion regarding the hiring of IT professionals in regards to the option of hiring new IT employees versus promoting internally for IT positions. After thinking a little more about this question regarding staffing, specifically pertaining to promoting internally verses new employees; I think my answer to this question is that it truly depends on the situation. However, in most cases I would side with promoting internally. The key factors in this decision should be based on a company/department’s current values, culture, attitude, and existing priorities.  For example if a company values retaining all of its hard earned business knowledge then they would tend to promote existing employees internal over hiring a new employee. Moreover, the company will have to pay to train an existing employee to learn a new technology and the learning curve for some technologies can be very steep. Conversely, if a company values new technologies and technical proficiency over business knowledge then a company would tend to hire new employees because they may already have experience with a technology that the company is planning on using. In this scenario, the company would have to take on the additional overhead of allowing a new employee to learn how the business operates prior to them being fully effective. To illustrate my points above let us look at contractor that builds in ground pools for example.  He has the option to hire employees that are very strong but use small shovels to dig, or employees weak in physical strength but use large shovels to dig. Which employee should the contractor use to dig a hole for a new in ground pool? If we compare the possible candidates for this job we will find that they are very similar to hiring someone internally verses a new hire. The first example represents the existing workers that are very strong regarding the understanding how the business operates and the reasons why in a specific manner. However this employee could be potentially weaker than an outsider pertaining to specific technologies and would need some time to build their technical prowess for a new position much like the strong worker upgrading their shovels in order to remove more dirt at once when digging. The other employee is very similar to hiring a new person that may already have the large shovel but will need to increase their strength in order to use the shovel properly and efficiently so that they can move a maximum amount of dirt in a minimal amount of time. This can be compared to new employ learning how a business operates before they can be fully functional and integrated in the company/department. Another key factor in this dilemma pertains to existing employee and their passion for their work, their ability to accept new responsibility when given, and the willingness to take on responsibilities when they see a need in the business. As much as possible should be considered in this decision down to the mood of the team, the quality of existing staff, learning cure for both technology and business, and the potential side effects of the existing staff.  In addition, there are many more consideration based on the current team/department/companies culture and mood. There are several factors that need to be considered when promoting an individual or hiring new blood for a team. They both can provide great benefits as well as create controversy to a group. Personally, staffing especially in the IT world is like building a large scale system in that all of the components and modules must fit together and preform as one cohesive system in the same way a team must come together using their individually acquired skills so that they can work as one team.  If a module is out of place or is nonexistent then the rest of the team will suffer until the all of its issues are addressed and resolved. Benefits of Promoting Internally Internal promotions give employees a reason to constantly upgrade their technology, business, and communication skills if they want to further their career Employees can control their own destiny based on personal desires Employee already knows how the business operates Companies can save money by promoting internally because the initial overhead of allowing new hires to learn how a company operates is very expensive Newly promoted employees can assist in training their replacements while transitioning to their new role within a company. Existing employees already have a proven track record in regards fitting in with the business culture; this is always an unknown with all new hires Benefits of a New Hire New employees can energize and excite existing employees New employees can bring new ideas and advancements in technology New employees can offer a different perspective on existing issues based on their past experience. As you can see the decision to promote an existing employee from within a company verses hiring a new person should be based on several factors that should ultimately place the business in the best possible situation for the immediate and long term future. How would you handle this situation? Would you hire a new employee or promote from within?

  • Linked Server related

    - by rmdussa
    I have two instances of SQL Server: Server1 (SQL Server 2008) Server2 (SQL Server 2005) I am executing a stored procedure from Server1 which references tables on Server2. It is working fine in my test environment: Server1 runs Vista SP2, SQL Server 2008; Server2 runs Windows XP SP2, SQL Server 2005. However, it is not working in the production environment: Server1 runs Vista SP1, SQL Server 2008; Server2 runs Windows XP SP2, SQL Server 2005. The error message I receive is: OLE DB provider "SQLNCLI10" for linked server "Server2" returned message "No transaction is active.". Msg 7391, Level 16, State 2, Line 21 The operation could not be performed because OLE DB provider "SQLNCLI10" for linked server "Server2" was unable to begin a distributed transaction.

  • Reported error code considered SQL Injection?

    - by inquam
    SQL injection that actually runs a SQL command is one thing. But injecting data that doesn't actually run a harmful query but that might tell you something valuable about the database, is that considered SQL injection? Or is it just used as part to construct a valid SQL injection? An example could be set rs = conn.execute("select headline from pressReleases where categoryID = " & cdbl(request("id")) ) Passing this a string that could not be turned into a numeric value would cause Microsoft VBScript runtime error '800a000d' Type mismatch: 'cdbl' which would tell you that the column in question only accepts numeric data and is thus probably of type integer or similar. I seem to find this in a lot of pages discussing SQL injection, but don't really get an answer if this in itself is considered SQL injection. The reason for my question is that I have a scanning tool that report a SQL injection vulnerability and reports a VBScript runtime error '800a000d' as the reason for the finding.

  • new with exception with Microsoft

    - by wsd
    As I'm coding for both Windows and Linux, I have a whole host of problems. Microsoft Visual C++ has no stdint header, but for that I wrote my own. Now I found out that MS C++'s new operator does not throw an exception, so I want to fix this a quickly as possible. I know I can define a Macro with Parameters in Parenthesis, can I define a macro that replaces MyClass x = new MyClass(); with #ifdef MSC_VER if(!(MyClass x = new MyClass()) { throw new std::bad_alloc(); } #else MyClass x = new MyClass(); #endif (or something equivalent), AND works in BOTH MS C++ and G++ ? Or alternatively if that is not possible, a batch file to run over the Code to do this? I have become rather dependent on this exception being thrown.

  • Fetch new Mails (Also from Subfolders) from another IMAP server as new Mail in Postfix

    - by Tobi
    everyone. I have installed Postfix on a server with Aliases and Domains from a MySQL Database. It is configured to forward some adresses to other Mail Accounts and also delivers some mails in local mailboxes that will be queried over a dovecot imap server. For this example let there be two users: [email protected] what is a user that gets its mail just forwarded to let's say [email protected] [email protected] what is a user that accesses its mail from local IMAP. Now, I want to fetch some Mails from another mailserver and handle them as if they were sent to a user of my Mailserver. Lets say those corelations exist: [email protected] has two external accounts: [email protected] and [email protected] [email protected] has also one external account [email protected] The Problem is the new mails on that other Mailserver is not always in the inbox, it might be in subdirectories: mailinglists/all or mailinglists/it but also in mailinglists/some-other-department which is not interesting and should not be delivered. I already found a programm called fetchmail but I cannot find how to fetch subdirectories or decide which subdirectories are fetched.

  • How to do regex HTML tag replace in SQL Server?

    - by timmerk
    I have a table in SQL Server 2005 with hundreds of rows with HTML content. Some of the content has HTML like: <span class=heading-2>Directions</span> where "Directions" changes depending on page name. I need to change all the <span class=heading-2> and </span> tags to <h2> and </h2> tags. I wrote this query to do content changes in the past, but it doesn't work for my current problem because of the ending HTML tag: Update ContentManager Set ContentManager.Content = replace(Cast(ContentManager.Content AS NVARCHAR(Max)), 'old text', 'new text') Does anyone know how I could accomplish the span to h2 replacing purely in T-SQL? Everything I found showed I would have to do CLR integration. Thanks!

  • SQL Server - Schema/Code Analysis Rules - What would your rules include?

    - by Randy Minder
    We're using Visual Studio Database Edition (DBPro) to manage our schema. This is a great tool that, among the many things it can do, can analyse our schema and T-SQL code based on rules (much like what FxCop does with C# code), and flag certain things as warnings and errors. Some example rules might be that every table must have a primary key, no underscore's in column names, every stored procedure must have comments etc. The number of rules built into DBPro is fairly small, and a bit odd. Fortunately DBPro has an API that allows the developer to create their own. I'm curious as to the types of rules you and your DB team would create (both schema rules and T-SQL rules). Looking at some of your rules might help us decide what we should consider. Thanks - Randy

  • How do you implement caching in Linq to SQL?

    - by Glenn Slaven
    We've just started using LINQ to SQL at work for our DAL & we haven't really come up with a standard for out caching model. Previously we had being using a base 'DAL' class that implemented a cache manager property that all our DAL classes inherited from, but now we don't have that. I'm wondering if anyone has come up with a 'standard' approach to caching LINQ to SQL results? We're working in a web environment (IIS) if that makes a difference. I know this may well end up being a subjective question, but I still think the info would be valuable. EDIT: To clarify, I'm not talking about caching an individual result, I'm after more of an architecture solution, as in how do you set up caching so that all your link methods use the same caching architecture.
