  • MSMQ messages using HTTP just won't get delivered

    - by John Breakwell
    I'm starting off the blog with a discussion of an unusual problem that has hit a couple of my customers this month. It's not a problem you'd expect to bump into and the solution is potentially painful. Scenario You want to make use of the HTTP protocol to send MSMQ messages from one machine to another. You have installed HTTP support for MSMQ and have addressed your messages correctly but they will not leave the outgoing queue. There is no configuration for HTTP support - setup has already done all that for you (although you may want to check the most recent "Installation of the MSMQ HTTP Support Subcomponent" section of MSMQINST.LOG to see if anything DID go wrong) - so you can't tweak anything. Restarting services and servers makes no difference - the messages just will not get delivered. The problem is documented and resolved by Knowledgebase article 916699 "The message may not be delivered when you use the HTTP protocol to send a message to a server that is running Message Queuing 3.0". It is unlikely that you would be able to resolve the problem without the assistance of PSS because there are no messages that can be seen to assist you and only access to the source code exposes the root cause. As this communication is over HTTP, the IIS logs would be a good place to start. POST entries are logged which show that connectivity is working and message delivery is being attempted: #Software: Microsoft Internet Information Services 6.0 #Version: 1.0 #Date: 2006-09-12 12:11:29 #Fields: date time s-sitename s-ip cs-method cs-uri-stem cs-uri-query s-port cs-username c-ip cs(User-Agent) sc-status sc-substatus sc-win32-status 2006-09-12 12:12:12 W3SVC1 10.1.17.219 POST /msmq/private$/test - 80 - 10.2.200.3 - 200 0 0 If you capture the traffic with Network Monitor you can see the POST being sent to the server but you also see a response being returned to the client: HTTP: Response to Client; HTTP/1.1; Status Code = 500 - Internal Server Error "Internal Server Error" means we can probably stop looking at IIS and instead focus on the Message Queuing ISAPI extension (Mqise.dll). MSMQ 3.0 (Windows XP and Windows Server 2003) comes with error logging enabled by default but the log files are in binary format - MSMQ 2.0 generated logging in plain text. The symbolic information needed for formatting the files is not currently publicly available so log files have to be sent in to Microsoft PSS.  Although this does mean raising a support case, formatting the log files to text and returning them to the customer shouldn't take long. Obviously the engineer analyses them for you - I just want to point out that you can see the logging output in text format if you want it. The important entries in the log for this problem are: [7]b48.928 09/12/2006-13:20:44.552 [mqise GetNetBiosNameFromIPAddr] ERROR:Failed to get the NetBios name from the DNS name, error = 0xea [7]b48.928 09/12/2006-13:20:44.552 [mqise RPCToServer] ERROR:RPC call R_ProcessHTTPRequest failed, error code = 1702(RPC_S_INVALID_BINDING) which allow a Microsoft escalation engineer to check the MQISE source code to see what is going wrong. This problem according to the article occurs when the extension tries to bind to the local MSMQ service after the extension receives a POST request that contains an MSMQ message. MSMQ resolves the server name by using the DNS host name but the extension cannot bind to the service because the buffer that MSMQ uses to resolve the server name is too small - server names that are exactly 15 characters long will not fit. RPC exception 0x6a6 (RPC_S_INVALID_BINDING) occurs in the W3wp.exe process but the exception is handled and so you do not receive an error message. The workaround is to rename the MSMQ server to something less than 15 characters. If the problem has only just been noticed in a production environment - an application may have been modified to get through a newly-implemented firewall, for example - then renaming is going to be an issue. Other applications may need to be reinstalled or modified if server names are hard-coded or stored in the registry. The renaming may also break a company naming convention where the name is built up from something like location+department+number. If you want to learn more about MSMQ logging then check out Chapter 15 of the MSMQ FAQ. In fact, even if you DON'T want to learn anything about MSMQ logging you should read the FAQ anyway as there is a huge amount of useful information on known issues and the like.

  • htaccess rewriterule works in one virtualhost, but not a second virtualhost

    - by Casey Flynn
    I have two virtualhosts configured with xampp on mac os x snow lion. Both use the following .htaccess file. <IfModule mod_rewrite.c> RewriteEngine On RewriteBase / # Protect hidden files from being viewed <Files .*> Order Deny,Allow Deny From All </Files> #Removes access to the system folder by users. #Additionally this will allow you to create a System.php controller, #previously this would not have been possible. #'system' can be replaced if you have renamed your system folder. RewriteCond %{REQUEST_URI} ^system.* RewriteRule ^(.*)$ /index.php?/$1 [L] #When your application folder isn't in the system folder #This snippet prevents user access to the application folder #Submitted by: Fabdrol #Rename 'application' to your applications folder name. RewriteCond %{REQUEST_URI} ^application.* RewriteRule ^(.*)$ /index.php?/$1 [L] #Checks to see if the user is attempting to access a valid file, #such as an image or css document, if this isn't true it sends the #request to index.php RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule ^(.*)$ index.php/$01 [L] # If we don't have mod_rewrite installed, all 404's # can be sent to index.php, and everything works as normal. # Submitted by: ElliotHaughin ErrorDocument 404 /index.php My goal is to eliminate /index.php/ from my url strings. This htaccess works perfectly for one project, but not for the other (project/vhost) This is my vhosts.conf # # This is the main Apache HTTP server configuration file. It contains the # configuration directives that give the server its instructions. # See <URL:http://httpd.apache.org/docs/2.2> for detailed information. # In particular, see # <URL:http://httpd.apache.org/docs/2.2/mod/directives.html> # for a discussion of each configuration directive. # # Do NOT simply read the instructions in here without understanding # what they do. They're here only as hints or reminders. If you are unsure # consult the online docs. You have been warned. # # Configuration and logfile names: If the filenames you specify for many # of the server's control files begin with "/" (or "drive:/" for Win32), the # server will use that explicit path. If the filenames do *not* begin # with "/", the value of ServerRoot is prepended -- so "logs/foo.log" # with ServerRoot set to "/Applications/xampp/xamppfiles" will be interpreted by the # server as "/Applications/xampp/xamppfiles/logs/foo.log". # # ServerRoot: The top of the directory tree under which the server's # configuration, error, and log files are kept. # # Do not add a slash at the end of the directory path. If you point # ServerRoot at a non-local disk, be sure to point the LockFile directive # at a local disk. If you wish to share the same ServerRoot for multiple # httpd daemons, you will need to change at least LockFile and PidFile. # ServerRoot "/Applications/XAMPP/xamppfiles" # # Listen: Allows you to bind Apache to specific IP addresses and/or # ports, instead of the default.

  • Logging WebSocket Frames using Chrome Developer Tools, Net-internals and Wireshark (TOTD #184)

    - by arungupta
    TOTD #183 explained how to build a WebSocket-driven application using GlassFish 4. This Tip Of The Day (TOTD) will explain how do view/debug on-the-wire messages, or frames as they are called in WebSocket parlance, over this upgraded connection. This blog will use the application built in TOTD #183. First of all, make sure you are using a browser that supports WebSocket. If you recall from TOTD #183 then WebSocket is combination of Protocol and JavaScript API. A browser supporting WebSocket, or not, means they understand your web pages with the WebSocket JavaScript. caniuse.com/websockets provide a current status of WebSocket support in different browsers. Most of the major browsers such as Chrome, Firefox, Safari already support WebSocket for the past few versions. As of this writing, IE still does not support WebSocket however its planned for a future release. Viewing WebSocket farmes require special settings because all the communication happens over an upgraded HTTP connection over a single TCP connection. If you are building your application using Java, then there are two common ways to debug WebSocket messages today. Other language libraries provide different mechanisms to log the messages. Lets get started! Chrome Developer Tools provide information about the initial handshake only. This can be viewed in the Network tab and selecting the endpoint hosting the WebSocket endpoint. You can also click on "WebSockets" on the bottom-right to show only the WebSocket endpoints. Click on "Frames" in the right panel to view the actual frames being exchanged between the client and server. The frames are not refreshed when new messages are sent or received. You need to refresh the panel by clicking on the endpoint again. To see more detailed information about the WebSocket frames, you need to type "chrome://net-internals" in a new tab. Click on "Sockets" in the left navigation bar and then on "View live sockets" to see the page. Select the box with the address to your WebSocket endpoint and see some basic information about connection and bytes exchanged between the client and the endpoint. Clicking on the blue text "source dependency ..." shows more details about the handshake. If you are interested in viewing the exact payload of WebSocket messages then you need a network sniffer. These tools are used to snoop network traffic and provide a lot more details about the raw messages exchanged over the network. However because they provide lot more information so they need to be configured in order to view the relevant information. Wireshark (nee Ethereal) is a pretty standard tool for sniffing network traffic and will be used here. For this blog purpose, we'll assume that the WebSocket endpoint is hosted on the local machine. These tools do allow to sniff traffic across the network though. Wireshark is quite a comprehensive tool and we'll capture traffic on the loopback address. Start wireshark, select "loopback" and click on "Start". By default, all traffic information on the loopback address is displayed. That includes tons of TCP protocol messages, applications running on your local machines (like GlassFish or Dropbox on mine), and many others. Specify "http" as the filter in the top-left. Invoke the application built in TOTD #183 and click on "Say Hello" button once. The output in wireshark looks like Here is a description of the messages exchanged: Message #4: Initial HTTP request of the JSP page Message #6: Response returning the JSP page Message #16: HTTP Upgrade request Message #18: Upgrade request accepted Message #20: Request favicon Message #22: Responding with favicon not found Message #24: Browser making a WebSocket request to the endpoint Message #26: WebSocket endpoint responding back You can also use Fiddler to debug your WebSocket messages. How are you viewing your WebSocket messages ? Here are some references for you: JSR 356: Java API for WebSocket - Specification (Early Draft) and Implementation (already integrated in GlassFish 4 promoted builds) TOTD #183 - Getting Started with WebSocket in GlassFish Subsequent blogs will discuss the following topics (not necessary in that order) ... Binary data as payload Custom payloads using encoder/decoder Error handling Interface-driven WebSocket endpoint Java client API Client and Server configuration Security Subprotocols Extensions Other topics from the API

  • MySQL Connect 8 Days Away - Replication Sessions

    - by Mat Keep
    Following on from my post about MySQL Cluster sessions at the forthcoming Connect conference, its now the turn of MySQL Replication - another technology at the heart of scaling and high availability for MySQL. Unless you've only just returned from a 6-month alien abduction, you will know that MySQL 5.6 includes the largest set of replication enhancements ever packaged into a single new release: - Global Transaction IDs + HA utilities for self-healing cluster..(yes both automatic failover and manual switchover available!) - Crash-safe slaves and binlog - Binlog Group Commit and Multi-Threaded Slaves for high performance - Replication Event Checksums and Time-Delayed replication - and many more There are a number of sessions dedicated to learn more about these important new enhancements, delivered by the same engineers who developed them. Here is a summary Saturday 29th, 13.00 Replication Tips and Tricks, Mats Kindahl In this session, the developers of MySQL Replication present a bag of useful tips and tricks related to the MySQL 5.5 GA and MySQL 5.6 development milestone releases, including multisource replication, using logs for auditing, handling filtering, examining the binary log, using relay slaves, splitting the replication stream, and handling failover. Saturday 29th, 17.30 Enabling the New Generation of Web and Cloud Services with MySQL 5.6 Replication, Lars Thalmann This session showcases the new replication features, including • High performance (group commit, multithreaded slave) • High availability (crash-safe slaves, failover utilities) • Flexibility and usability (global transaction identifiers, annotated row-based replication [RBR]) • Data integrity (event checksums) Saturday 29th, 1900 MySQL Replication Birds of a Feather In this session, the MySQL Replication engineers discuss all the goodies, including global transaction identifiers (GTIDs) with autofailover; multithreaded, crash-safe slaves; checksums; and more. The team discusses the design behind these enhancements and how to get started with them. You will get the opportunity to present your feedback on how these can be further enhanced and can share any additional replication requirements you have to further scale your critical MySQL-based workloads. Sunday 30th, 10.15 Hands-On Lab, MySQL Replication, Luis Soares and Sven Sandberg But how do you get started, how does it work, and what are the best practices and tools? During this hands-on lab, you will learn how to get started with replication, how it works, architecture, replication prerequisites, setting up a simple topology, and advanced replication configurations. The session also covers some of the new features in the MySQL 5.6 development milestone releases. Sunday 30th, 13.15 Hands-On Lab, MySQL Utilities, Chuck Bell Would you like to learn how to more effectively manage a host of MySQL servers and manage high-availability features such as replication? This hands-on lab addresses these areas and more. Participants will get familiar with all of the MySQL utilities, using each of them with a variety of options to configure and manage MySQL servers. Sunday 30th, 14.45 Eliminating Downtime with MySQL Replication, Luis Soares The presentation takes a deep dive into new replication features such as global transaction identifiers and crash-safe slaves. It also showcases a range of Python utilities that, combined with the Release 5.6 feature set, results in a self-healing data infrastructure. By the end of the session, attendees will be familiar with the new high-availability features in the whole MySQL 5.6 release and how to make use of them to protect and grow their business. Sunday 30th, 17.45 Scaling for the Web and the Cloud with MySQL Replication, Luis Soares In a Replication topology, high performance directly translates into improving read consistency from slaves and reducing the risk of data loss if a master fails. MySQL 5.6 introduces several new replication features to enhance performance. In this session, you will learn about these new features, how they work, and how you can leverage them in your applications. In addition, you will learn about some other best practices that can be used to improve performance. So how can you make sure you don't miss out - the good news is that registration is still open ;-) And just to whet your appetite, listen to the On-Demand webinar that presents an overview of MySQL 5.6 Replication.

  • Setting up Mono/ASP.NET 4.0 on Apache2/Ubuntu: Virtual hosts?

    - by Dave
    I'm attempting to setup Mono/ASP.NET 4.0 on my Apache server (which is running on Ubuntu). Thus far, I've been following a few tutorials/scripts supplied here, and here. As of now: Apache 2.2 is installed (accessible via 'localhost') Mono 2.10.5 is installed However, I'm struggling to configure Apache correctly... apparently the Virtual Host setting isn't doing its job and invoking the mod_mono plugin, nor is it even pulling source from the proper directory. While the Virtual Host setting points to '\srv\www\localhost', it clearly is pulling content instead from 'var/www/', which I've found is the default DocumentRoot for virtual hosts. I can confirm: "/opt/mono-2.10/bin/mod-mono-server4" exists. Virtual hosts file is being read, since undoing the comment in the main httpd.conf changed the root directory from 'htdocs' to 'var/www/' The Mono installation is at least semi-capable of running ASP 4.0, as evidenced by running XSP, navigating to 0.0.0.0:8080/ and getting an ASP.NET style error page with "Mono ASP 4.0.x" at the bottom. Can anyone point out how to fix these configurations and get Mono linked up with Apache? Here are my configs and relevant information: /usr/local/apache2/conf/httpd.conf: # # This is the main Apache HTTP server configuration file. It contains the # configuration directives that give the server its instructions. # See <URL:http://httpd.apache.org/docs/2.2> for detailed information. # In particular, see # <URL:http://httpd.apache.org/docs/2.2/mod/directives.html> # for a discussion of each configuration directive. # # Do NOT simply read the instructions in here without understanding # what they do. They're here only as hints or reminders. If you are unsure # consult the online docs. You have been warned. # # Configuration and logfile names: If the filenames you specify for many # of the server's control files begin with "/" (or "drive:/" for Win32), the # server will use that explicit path. If the filenames do *not* begin # with "/", the value of ServerRoot is prepended -- so "logs/foo_log" # with ServerRoot set to "/usr/local/apache2" will be interpreted by the # server as "/usr/local/apache2/logs/foo_log". # # ServerRoot: The top of the directory tree under which the server's # configuration, error, and log files are kept. # # Do not add a slash at the end of the directory path. If you point # ServerRoot at a non-local disk, be sure to point the LockFile directive # at a local disk. If you wish to share the same ServerRoot for multiple # httpd daemons, you will need to change at least LockFile and PidFile. # ServerRoot "/usr/local/apache2" # # Listen: Allows you to bind Apache to specific IP addresses and/or # ports, instead of the default. See also the <VirtualHost> # directive. # # Change this to Listen on specific IP addresses as shown below to # prevent Apache from glomming onto all bound IP addresses. # #Listen 12.34.56.78:80 Listen 80 # # Dynamic Shared Object (DSO) Support # # To be able to use the functionality of a module which was built as a DSO you # have to place corresponding `LoadModule' lines at this location so the # directives contained in it are actually available _before_ they are used. # Statically compiled modules (those listed by `httpd -l') do not need # to be loaded here. # # Example: # LoadModule foo_module modules/mod_foo.so # <IfModule !mpm_netware_module> <IfModule !mpm_winnt_module> # # If you wish httpd to run as a different user or group, you must run # httpd as root initially and it will switch. # # User/Group: The name (or #number) of the user/group to run httpd as. # It is usually good practice to create a dedicated user and group for # running httpd, as with most system services. # User daemon Group daemon </IfModule> </IfModule> # 'Main' server configuration # # The directives in this section set up the values used by the 'main' # server, which responds to any requests that aren't handled by a # <VirtualHost> definition. These values also provide defaults for # any <VirtualHost> containers you may define later in the file. # # All of these directives may appear inside <VirtualHost> containers, # in which case these default settings will be overridden for the # virtual host being defined. # # # ServerAdmin: Your address, where problems with the server should be # e-mailed. This address appears on some server-generated pages, such # as error documents. e.g. [email protected] # ServerAdmin david@localhost # # ServerName gives the name and port that the server uses to identify itself. # This can often be determined automatically, but we recommend you specify # it explicitly to prevent problems during startup. # # If your host doesn't have a registered DNS name, enter its IP address here. # ServerName localhost:80 # # DocumentRoot: The directory out of which you will serve your # documents.

  • Subterranean IL: Pseudo custom attributes

    - by Simon Cooper
    Custom attributes were designed to make the .NET framework extensible; if a .NET language needs to store additional metadata on an item that isn't expressible in IL, then an attribute could be applied to the IL item to represent this metadata. For instance, the C# compiler uses DecimalConstantAttribute and DateTimeConstantAttribute to represent compile-time decimal or datetime constants, which aren't allowed in pure IL, and FixedBufferAttribute to represent fixed struct fields. How attributes are compiled Within a .NET assembly are a series of tables containing all the metadata for items within the assembly; for instance, the TypeDef table stores metadata on all the types in the assembly, and MethodDef does the same for all the methods and constructors. Custom attribute information is stored in the CustomAttribute table, which has references to the IL item the attribute is applied to, the constructor used (which implies the type of attribute applied), and a binary blob representing the arguments and name/value pairs used in the attribute application. For example, the following C# class: [Obsolete("Please use MyClass2", true)] public class MyClass { // ... } corresponds to the following IL class definition: .class public MyClass { .custom instance void [mscorlib]System.ObsoleteAttribute::.ctor(string, bool) = { string('Please use MyClass2' bool(true) } // ... } and results in the following entry in the CustomAttribute table: TypeDef(MyClass) MemberRef(ObsoleteAttribute::.ctor(string, bool)) blob -> {string('Please use MyClass2' bool(true)} However, there are some attributes that don't compile in this way. Pseudo custom attributes Just like there are some concepts in a language that can't be represented in IL, there are some concepts in IL that can't be represented in a language. This is where pseudo custom attributes come into play. The most obvious of these is SerializableAttribute. Although it looks like an attribute, it doesn't compile to a CustomAttribute table entry; it instead sets the serializable bit directly within the TypeDef entry for the type. This flag is fully expressible within IL; this C#: [Serializable] public class MySerializableClass {} compiles to this IL: .class public serializable MySerializableClass {} For those interested, a full list of pseudo custom attributes is available here. For the rest of this post, I'll be concentrating on the ones that deal with P/Invoke. P/Invoke attributes P/Invoke is built right into the CLR at quite a deep level; there are 2 metadata tables within an assembly dedicated solely to p/invoke interop, and many more that affect it. Furthermore, all the attributes used to specify p/invoke methods in C# or VB have their own keywords and syntax within IL. For example, the following C# method declaration: [DllImport("mscorsn.dll", SetLastError = true)] [return: MarshalAs(UnmanagedType.U1)] private static extern bool StrongNameSignatureVerificationEx( [MarshalAs(UnmanagedType.LPWStr)] string wszFilePath, [MarshalAs(UnmanagedType.U1)] bool fForceVerification, [MarshalAs(UnmanagedType.U1)] ref bool pfWasVerified); compiles to the following IL definition: .method private static pinvokeimpl("mscorsn.dll" lasterr winapi) bool marshal(unsigned int8) StrongNameSignatureVerificationEx( string marshal(lpwstr) wszFilePath, bool marshal(unsigned int8) fForceVerification, bool& marshal(unsigned int8) pfWasVerified) cil managed preservesig {} As you can see, all the p/invoke and marshal properties are specified directly in IL, rather than using attributes. And, rather than creating entries in CustomAttribute, a whole bunch of metadata is emitted to represent this information. This single method declaration results in the following metadata being output to the assembly: A MethodDef entry containing basic information on the method Four ParamDef entries for the 3 method parameters and return type An entry in ModuleRef to mscorsn.dll An entry in ImplMap linking ModuleRef and MethodDef, along with the name of the function to import and the pinvoke options (lasterr winapi) Four FieldMarshal entries containing the marshal information for each parameter. Phew! Applying attributes Most of the time, when you apply an attribute to an element, an entry in the CustomAttribute table will be created to represent that application. However, some attributes represent concepts in IL that aren't expressible in the language you're coding in, and can instead result in a single bit change (SerializableAttribute and NonSerializedAttribute), or many extra metadata table entries (the p/invoke attributes) being emitted to the output assembly.

  • What makes them click ?

    - by Piet
    The other day (well, actually some weeks ago while relaxing at the beach in Kos) I read ‘Neuro Web Design - What makes them click?’ by Susan Weinschenk. (http://neurowebbook.com) The book is a fast and easy read (no unnecessary filler) and a good introduction on how your site’s visitors can be steered in the direction you want them to go. The Obvious The book handles some of the more known/proven techniques, like for example that ratings/testimonials of other people can help sell your product or service. Another well known technique it talks about is inducing a sense of scarcity/urgency in the visitor. Only 2 seats left! Buy now and get 33% off! It’s not because these are known techniques that they stop working. Luckily 2/3rd of the book handles less obvious techniques, otherwise it wouldn’t be worth buying. The Not So Obvious A less known influencing technique is reciprocity. And then I’m not talking about swapping links with another website, but the fact that someone is more likely to do something for you after you did something for them first. The book cites some studies (I always love the facts and figures) and gives some actual examples of how to implement this in your site’s design, which is less obvious when you think about it. Want to know more ? Buy the book! Other interesting sources For a more general introduction to the same principles, I’d suggest ‘Yes! 50 Secrets from the Science of Persuasion’. ‘Yes!…’ cites some of the same studies (it seems there’s a rather limited pool of studies covering this subject), but of course doesn’t show how to implement these techniques in your site’s design. I read ‘Yes!…’ last year, making ‘Neuro Web Design’ just a little bit less interesting. !!!Always make sure you’re able to measure your changes. If you haven’t yet, check out the advanced segmentation in Google Analytics (don’t be afraid because it says ‘beta’, it works just fine) and Google Website Optimizer. Worth Buying? Can I recommend it ? Sure, why not. I think it can be useful for anyone who ever had to think about the design or content of a site. You don’t have to be a marketing guy to want a site you’re involved with to be successful. The content/filler ratio is excellent too: you don’t need to wade through dozens of pages to filter out the interesting bits. (unlike ‘The Design of Sites’, which contains too much useless info and because it’s in dead-tree format, you can’t google it) If you like it, you might also check out ‘Yes! 50 Secrets from the Science of Persuasion’. Tip for people living in Europe: check Amazon UK for your book buying needs. Because of the low UK Pound exchange rate, it’s usually considerably cheaper and faster to get a book delivered to your doorstep by Amazon UK compared to having to order it at the local book store or web-shop.

  • SQL SERVER – Top 10 “Ease of Use” Features of expressor Studio

    - by pinaldave
    expressor Studio is new data integration platform that is being marketed as the most easy to use tool of its kind.  But “easy to use” can be a relative term – an expert can find a very complex system easy, but a beginner might be stumped.  A recent article online discussed exactly what makes expressor Studio so easy use, and here is my view on this subject. Simple Installation There is one pop-up for one .exe file, and nothing more.  You can’t get much simpler than this.  It is also in the familiar Windows design, so there should be no surprises. No 3rd party software dependency Have you ever tried to download software, only to be slowed down by the need to download a compatible system to run the program, and another to read the user manual, and so on?  expressor Studio was designed specifically to avoid this problem. Microsoft Office Like Ribbon Bar and Menus As mentioned before, everything is in the familiar Windows design, from the pop up windows to the tool bars and menus.  There should be no learning curve for using this program, or even simply trying to navigate around a new system. General Development Design Interface This software has been designed to be simple and straightforward.  Projects can be arranged in a simple “tree” design, that is totally collapsible and can easy be added to or “trimmed” with a click of a button.  It was meant to be logical and easy to follow. Integrated Contextual Help This is a fancy way of saying that you can practically yell “help!” if you do get stuck on something.  Solving a problem is as simple as highlighting and hitting F1 for contextual help. Visual Indicators and Messages Wouldn’t it be nice to know exactly where something has gone wrong before trying to complete a project.  expressor Studio has a built in system to catch mistakes and highlight them in a bright color, flash a warning message, and even disable functions before you can continue – and possibly lose hours of work. Property Inputs and Selectors Every operator will have a list of requirements that need to be filled in.  But don’t worry; you won’t have to make stuff up to fill in the boxes.  Each one will have a drop-down menu with options to choose from – but not too many as to be confusing. Connection Wizards Configuring connections can be the hardest part of a project.  But not with the expressor Studioconnection wizard.  A familiar, Windows-style menu will walk you through connections so quickly you’ll forget what trouble it used to be. Templates With large, complex projects, a majority of your time is often spent simply setting up the files and inputting data.  But expressor Studio allows you to create one file and then save it as a template, saving you hours of boring data input. Extension Manager Let’s say that you need a little more functionality or some new features on your program. A lot of software requires you to download complex plug-ins that need to be decompressed and installed.  However, expressor Studio has extended its system to an Extension Manager, which allows for quick and easy installation of the functionality you need, without the need to download and decompress.

  • Drupal Modules for SEO & Content

    - by Aditi
    When we talk about Drupal SEO, there are two things to consider one is about the relevant SEO practices and about appropriate Drupal Modules available. Optimizing your website for search engines is one of the most important aspect of launching & promoting your website especially if ranking matters to you. Understanding SEO For starters, you have begin with Keyword research and then optimize your content according to your findings by tagging, meta tags etc, Drupal modules once installed help you manage a lot of such parameters. Identifying the target keywords Using the Page Title and Token modules PathAuto configuration <H1> heading tags Optimizing Drupal’s default robots.txt file Etc. While Drupal gives you a lot of ability to make your website content worthy & search engine friendly it is important for you to make sure you are not crossing the line or you could get penalized. Modules Overview Drupal Power is at its best when you have these modules & great brain working together. The basic SEO improvements can be achieved easily with the modules enlisted below, but you can win magical rankings if you use them logically & wisely. Understanding your keyword competition & enhancing your content is the basic key to success and ofcourse the modules: Pathauto Automatically create search enging friendly readable URLS from tokens. A token is a piece of data from content, say the author’s username, or the content’s title. For example mysite.com/an-article, rather than mysite.com/node/114 for every node you make. NodeWords Amazingly useful drupal module that allows you to create custom meta tags and descriptions for your nodes, which gives you the ability to target specific keywords and phrases. Page Title Enables you to set an alternative title for the <title></title> tags and for the <h1></h1> tags on a node. Global Redirect Manage content duplication, 301 redirects, and URL validation with this small, but powerful module. Taxonomy manager Make large additions, or changes to taxonomy very easy. This module provides a powerful interface for managing taxonomies. A vocabulary gets displayed in a dynamic tree view, where parent terms can be expanded to list their nested child terms or can be collapsed. robotstxt A robots.txt file is vital for ensuring that search engine spiders don’t index the unwanted areas of your site. This Drupal module gives you the ability to manage your robots.txt file through the CMS admin. xmlsitemap An XML Sitemap lets the search engines index your website content. This module helps in generating and maintaining a complete sitemap for your website and gives you control over exactly which parts of the site you want to be included in the index. It even gives you the ability to automatically submit your sitemap to Google, Yahoo!, Ask.com and Windows Live every time you update a node or at specific interval. Node Import This module allows you to import a set of nodes from a Comma Seperated Values (CSV) or Tab Seperated Values (TSV) text file. Makes it easy to import hundreds-thousands of csv rows and you get to tie up these rows to CCK fields (or locations), and it can file it under the right taxonomy hierarchy. This is Super life saver module.

  • Excel Template Teaser

    - by Tim Dexter
    In lieu of some official documentation I'm in the process of putting together some posts on the new 10.1.3.4.1 Excel templates. No more HTML, maskerading as Excel; far more flexibility than Excel Analyzer and no need to write complex XSL templates to create the same output. Multi sheet outputs with macros and embeddable XSL commands are here. Their capabilities are pretty extensive and I have not worked on them for a few years since I helped put them together for EBS FSG users, so Im back on the learning curve. Let me say up front, there is no template builder, its a completely manual process to build them but, the results can be fantastic and provide yet another 'superstar' opportunity for you. The templates can take hierarchical XML data and walk the structure much like an RTF template. They use named cells/ranges and a hidden sheet to provide the rendering engine the hooks to drop the data in. As a taster heres the data and output I worked with on my first effort: <EMPLOYEES> <LIST_G_DEPT> <G_DEPT> <DEPARTMENT_ID>10</DEPARTMENT_ID> <DEPARTMENT_NAME>Administration</DEPARTMENT_NAME> <LIST_G_EMP> <G_EMP> <EMPLOYEE_ID>200</EMPLOYEE_ID> <EMP_NAME>Jennifer Whalen</EMP_NAME> <EMAIL>JWHALEN</EMAIL> <PHONE_NUMBER>515.123.4444</PHONE_NUMBER> <HIRE_DATE>1987-09-17T00:00:00.000-06:00</HIRE_DATE> <SALARY>4400</SALARY> </G_EMP> </LIST_G_EMP> <TOTAL_EMPS>1</TOTAL_EMPS> <TOTAL_SALARY>4400</TOTAL_SALARY> <AVG_SALARY>4400</AVG_SALARY> <MAX_SALARY>4400</MAX_SALARY> <MIN_SALARY>4400</MIN_SALARY> </G_DEPT> ... </LIST_G_DEPT> </EMPLOYEES> Structured XML coming from a data template, check out the data template progression post. I can then generate the following binary XLS file. There are few cool things to notice in this output. DEPARTMENT-EMPLOYEE master detail output. Not easy to do in the Excel analyzer. Date formatting - this is using an Excel function. Remember BIP generates XML dates in the canonical format. I have formatted the other data in the template using native Excel functionality Salary Total - although in the data I have calculated this in the template Conditional formatting - this is handled by Excel based on the incoming data Bursting department data across sheets and using the department name for the sheet name. This alone is worth the wait! there's more, but this is surely enough to whet your appetite. These new templates are already tucked away in EBS R12 under controlled release by the GL team and have now come to the BIEE and standalone releases in the 10.1.3.4.1+ rollup patch. For the rest of you, its going to be a bit of a waiting game for the relevant teams to uptake the latest BIP release. Look out for more soon with some explanation of how they work and how to put them together!

  • Adding Fake Build Information in TFS 2010

    - by Jakob Ehn
    We have been using TFS 2010 build for distributing a build in parallel on several agents, but where the actual compilation is done by a bunch of external tools and compilers, e.g. no MSBuild involved. We are using the ParallelTemplate.xaml template that Jim Lamb blogged about previously, which distributes each configuration to a different agent. We developed custom activities for running these external compilers and collecting the information and errors by reading standard out/error and pushing it back to the build log. But since we aren’t using MSBuild we don’t the get nice configuration summary section on the build summary page that we are used to. We would like to show the result of each configuration with any errors/warnings as usual, together with a link to the log file. TFS 2010 API to the rescue! What we need to do is adding information to the InformationNode structure that is associated with every TFS build. The log that you normally see in the Log view is built up as a tree structure of IBuildInformationNode objects. This structure can we accessed by using the InformationNodeConverters class. This class also contain some helper methods for creating BuildProjectNode, which contain the information about each project that was build, for example which configuration, number of errors and warnings and link to the log file. Here is a code snippet that first creates a “fake” build from scratch and the add two BuildProjectNodes, one for Debug|x86 and one for Release|x86 with some release information:   TfsTeamProjectCollection collection = TfsTeamProjectCollectionFactory.GetTeamProjectCollection(new Uri("http://lt-jakob2010:8080/tfs")); IBuildServer buildServer = collection.GetService<IBuildServer>(); var buildDef = buildServer.GetBuildDefinition("TeamProject", "BuildDefinition"); //Create fake build with random build number var detail = buildDef.CreateManualBuild(new Random().Next().ToString()); // Create Debug|x86 project summary IBuildProjectNode buildProjectNode = detail.Information.AddBuildProjectNode(DateTime.Now, "Debug", "MySolution.sln", "x86", "$/project/MySolution.sln", DateTime.Now, "Default"); buildProjectNode.CompilationErrors = 1; buildProjectNode.CompilationWarnings = 1; buildProjectNode.Node.Children.AddBuildError("Compilation", "File1.cs", 12, 5, "", "Syntax error", DateTime.Now); buildProjectNode.Node.Children.AddBuildWarning("File2.cs", 3, 1, "", "Some warning", DateTime.Now, "Compilation"); buildProjectNode.Node.Children.AddExternalLink("Log File", new Uri(@"\\server\share\logfiledebug.txt")); buildProjectNode.Save(); // Create Releaes|x86 project summary buildProjectNode = detail.Information.AddBuildProjectNode(DateTime.Now, "Release", "MySolution.sln", "x86", "$/project/MySolution.sln", DateTime.Now, "Default"); buildProjectNode.CompilationErrors = 0; buildProjectNode.CompilationWarnings = 0; buildProjectNode.Node.Children.AddExternalLink("Log File", new Uri(@"\\server\share\logfilerelease.txt")); buildProjectNode.Save(); detail.Information.Save(); detail.FinalizeStatus(BuildStatus.Failed); When running this code, it will a create a build that looks like this: As you can see, it created two configurations with error and warning information and a link to a log file. Just like a regular MSBuild would have done. This is very useful when using TFS 2010 Build in heterogeneous environments. It would also be possible to do this when running compilations completely outside TFS build, but then push the results of the into TFS for easy access. You can push all information, including the compilation summary, drop location, test results etc using the API.

  • 2010 April Fools Joke

    - by Dane Morgridge
    I started at my current job at the end of March last year and there were some pretty funny April fools jokes.  Nothing super crazy, but pretty funny.  One guy came in and there was a tree in his cube.  We (me and the rest of my team) were planning for a couple of weeks on what we could do that would be just awesome.  We had a lot of really good ideas but nothing was spectacular.  Then Steve Andrews had a brilliant idea (yes it's true).  Since we have internal DNS servers we could redirect DNS to our internal servers for a site such as cnn.com.  Then we would lift the code from the site and create our own home page that would contain news about people in the company.  Steve was actually laughing so hard when he thought of the idea that it took him almost 30 minutes to spit it out. I thought, "this is perfect". I had enlisted a couple of people to help come up with the stories and at the same time we were trying to figure out how to get everybody to the site the morning of the 1st.  Then it hit me.  We could have the main article be one of my getting picked up by the FBI on hacking charges.  Then Chris (my boss) could send an email out telling everyone that I would not be there today and direct them to the site.  That would for sure get everyone to go to cnn.com first thing and see our prank.  I begun the process of looking for photos I could crop myself into and found the perfect one.  Then my wife took a good pic with our Canon 40D and I went to work.  The night before I didn't have any other stories due to everyone being really busy at work, but I decided to go ahead with just the FBI bust on it's own.  I got everything working and tested and coordinated with Chris for me to come in late so no one would see me at the office until after everyone had seen the joke. And so the morning of April fools came and I was waiting at home and the email was perfect.  Chris told everyone that I wouldn't be in and that not to answer any questions if you got any calls from anybody.  The Photoshop job I did was not perfect, but good enough and I even wrote an article with it that went into more detail about how I had been classified as a terrorist and all kinds of stuff. People at work started getting the emails and a few people didn't realize it was a joke (as I had hoped), including some from senior management (one person in particular who shall remain nameless in this post).  Emails started flying around about how to contain the situation and how to handle bad PR.  He basically bought it hook, line and sinker and then went in to crisis mode.  It was awesome! He did finally realize it was a joke and I will likely print and frame the email he sent out.  In short, April fools this year was a huge success.

  • Assign highest priority to my local repository

    - by Anwar Shah
    Original question was : "How to assign highest priority to local repository without using sources.list file" I have setup a local repository with packages I downloaded. I use it to avoid downloading the same packages over the Internet, when I need to reinstall my Ubuntu. It is a basic repository, created with apt-ftparchive packages . > Packages. I made this a trusted repository to avoid "unauthenticated repository" warning. (When you have a untrusted repository, apt or synaptic try to download the same packages over the Internet, 'cause it is trusted). I have been using this local repository for at least 1 years. But I have to always put my local repository line at the top of the sources.list file to use this. But this is annoying, since I must open a terminal and do some typing on it every time I reinstall Ubuntu, though there is a better tool software-properties-gtk. I cannot use this tool since it place the source line at the end of `sources.list. And the real problem is that, the apt or synaptic always download a package from the source which is mentioned earlier, without inspecting whether the packages are already available in the local repository. So, I have no choice but to place the local source at the top of sources.list doing terminal (I actually don't hate terminal, but I need a solution) . I have tried this method. But this does not help me. My preference file is this in /etc/apt/preferences.d/local-pin-900 Package: * Pin: release o=Local,n=ubuntu-local Pin-Priority: 900 My release file is this Origin: Local Label: Local-Ubuntu Description: Local Ubuntu Repository Codename: ubuntu-local MD5Sum: ed43222856d18f389c637ac3d7dd6f85 1043412 Packages d41d8cd98f00b204e9800998ecf8427e 0 Sources When I enable the apt-preference, the apt-cache policy correctly shows the preference, e.g. It shows the local repository has the highest priority. But when I do this sudo apt-get install <package-name>, apt tries to download it from Internet. But when I place my local-repo at the top, it installs from local repository. So, My question is - 'Is it possible to force apt to use local repository when the package is available in local repository, without explicitly placing "the local source" at the top of my repository list (e.g sources.list file) ?' Edit: output of apt-cache policy $package_name is as follows nautilus-wipe: Installed: (none) Candidate: 0.1.1-2 Version table: 0.1.1-2 0 500 http://archive.ubuntu.com/ubuntu/ precise/universe i386 Packages 900 file:/media/Main/Linux-Software/Ubuntu/Precise/ Packages It is showing that my local repository has higher preference, though it is not the one which comes first in sources.list file. Here is the output of apt-get install nautilus-wipe Reading package lists... Done Building dependency tree Reading state information... Done The following NEW packages will be installed: nautilus-wipe 0 upgraded, 1 newly installed, 0 to remove and 131 not upgraded. Need to get 30.7 kB of archives. After this operation, 150 kB of additional disk space will be used. 'http://archive.ubuntu.com/ubuntu/pool/universe/n/nautilus-wipe/nautilus-wipe_0.1.1-2_i386.deb' nautilus-wipe_0.1.1-2_i386.deb 30730 MD5Sum:7d497b8dfcefe1c0b51a45f3b0466994 It is still trying to get the file from Internet, though I think it should be happy with the local one.

  • Steps for MySQL DB Replication

    - by Manish Agrawal
    Following are the steps for MySQL Replication implementation on Linux machine: Pre-implementation steps for DB Replication:   1.    Identify the databases to be replicated 2.    Identify the tables to be ignored during replication per database for example log tables 3.  Carefully identify and replace the variables and paths(locations) mentioned (in bold) in the commands given below with appropriate values 4.  Schedule the maintenance activity in odd hours as these activities will affect all the databases on Master database server       Implementation steps for DB Replication:     1.    Configure the /etc/my.cnf file on Master database server to enable Binary logging, setting of server id and configuring of dbnames for which logging should be done. [mysqld] log-bin=mysql-bin server-id=1 binlog-do-db = dbname   Note: You can specify multiple DB in binlog-do-db by using comma separated dbname values like: dbname1, dbname2, …, dbnameN   2.    On Master database, Grant Replication Slave Privileges, by executing following command on mysql prompt mysql> GRANT REPLICATION SLAVE ON *.* TO slaveuser@<hostname> identified by ‘slavepassword’;   3.    Stop the Master & Slave database by giving the command      mysqladmin shutdown   4.    Start the Master database by giving the command      /usr/local/mysql-5.0.22/bin/mysqld_safe --user=user&     5.    mysql> FLUSH TABLES WITH READ LOCK; Note: Leave the client (putty session) from which you issued the FLUSH TABLES statement running, so that the read lock remains in effect. If you exit the client, the lock is released. 6.    mysql > SHOW MASTER STATUS;          +---------------+----------+--------------+------------------+          | File          | Position | Binlog_Do_DB | Binlog_Ignore_DB |          +---------------+----------+--------------+------------------+          | mysql-bin.003 | 117       | dbname       |                  |          +---------------+----------+--------------+------------------+ Note: Note this information as this will be required while starting of Slave and replication in later steps   7.    Take MySQL dump by giving the following command, In another session window (putty window) run the following command: mysqldump –u user --ignore-table=dbname.tbl_name -–ignore-table=dbname.tbl_name2 --master-data dbname > dbname_dump.db Note: When choosing databases to include in the dump, remember that you will need to filter out databases on each slave that you do not want to include in the replication process.     8.    Unlock the tables on Master by giving following command: mysql> UNLOCK TABLES;   9.    Copy the dump file to Slave DB server   10.  Startup the Slave by using option --skip-slave      /usr/local/mysql-5.0.22/bin/mysqld_safe --user=user --skip-slave&   11.  Restore the dump file on Slave DB server      mysql –u user dbname < dbname_dump.db   12.  Stop the Slave database by giving the command      mysqladmin shutdown   13.  Configure the /etc/my.cnf file on the Slave database server [mysqld] server-id=2 replicate-ignore-table = dbname.tablename   14.  Start the Slave Mysql Server with 'replicate-do-db=DB name' option.      /usr/local/mysql-5.0.22/bin/mysqld_safe --user=user --replicate-do-db=dbname --skip-slave   15.  Configure the settings at Slave server for Master host name, log filename and position within the log file as shown in Step 6 above Use Change Master statement in the MySQL session mysql> CHANGE MASTER TO MASTER_HOST='<master_host_name>', MASTER_USER='<replication_user_name>', MASTER_PASSWORD='<replication_password>', MASTER_LOG_FILE='<recorded_log_file_name>', MASTER_LOG_POS=<recorded_log_position>;   16.  On Slave Servers mysql prompt give the following command: a.     mysql > START SLAVE; b.    mysql > SHOW SLAVE STATUS;         Note: To stop slave for backup or any other activity you can use the following command on the Slave Servers mysql prompt: mysql> STOP SLAVE     Refer following links for more information on MySQL DB Replication: http://dev.mysql.com/doc/refman/5.0/en/replication-options.html http://crazytoon.com/2008/04/21/mysql-replication-replicate-by-choice/ http://dev.mysql.com/doc/refman/5.0/en/mysqldump.html

  • How to install SharePoint Server 2013 Preview

    - by ybbest
    The Office 2013 and SharePoint Server 2013 Preview is announced yesterday and as a SharePoint Developer, I am really excited to learn all the new features and capabilities. Today I will show you how to install the preview. 1. Create a service account called SP2013Install and give this account Dbcreator and SecurityAdmin in SQL Server 2012 2. You need to run the following script to set the ‘maxdegree of parellism’ setting to the required value of 1 in SQL Server 2012(using sysadmin privilege) before configure the SharePoint Farm. Otherwise , you might get the error ‘This SQL Server Instance does not have the required maxdegree of parellism setting of 1’ sp_configure 'show advanced options', 1; GO RECONFIGURE WITH OVERRIDE; GO sp_configure 'max degree of parallelism', 1; GO RECONFIGURE WITH OVERRIDE; GO 3. Download the SharePoint preview from here and I am going to install it on Windows Server 2008R2 with SQL2012. 4. Click the Install software prerequisites, this works fine with the internet connection. (However, if you do not have internet connection, it is a bit tricky to install window azure AppFabric as it has to be installed using the prerequisite installer. Your computer might reboot a few times in the process.) 5.After the prerequisites are installed `completely, you can then install the Preview. Click the Install SharePoint Server and Enter the Product key you get from the Preview download page. 6. Accept the License terms and Click Next. 7. Leave the default path for the file location. 8. You can now start the installation process 9. After binary files are installed, you then can configure your farm using the farm configuration wizard. 10.Specify the Database server and the install account 11. Specify SharePoint farm passphrase. 12 Specify the port number , you should choose your own favorite port number. 13. Choose Create a New Server Farm and click next. 14. Double-check with the settings and click Next to Configure the farm install. 15. Finally, your farm is configured successfully and you now are able to go to your Central Admin site http://sp2010:6666/ 16. You should configure the services manually or automate using PowerShell (If you like to understand why,you can read the blog post here) ,however I will use the wizard to configure automatically here  as  this is a test machine. After the configuration is complete, you now be able to see your SharePoint Site. 17.To start the evaluate the Preview , you need to install Visual Studio 2012 RC , Microsoft Office Developer Tools for Visual Studio 2012,SharePoint 2013 Designer Preview , Office 2013 Preview. References: Download SharePoint2013 Server 2013 Download Microsoft Visio Professional 2013 Preview Install SharePoint 2013 Preview Hardware and software requirements for SharePoint 2013 Preview SharePoint 2013 IT Pro and Developer training materials released Plan for SharePoint 2013 Preview Microsoft Office Developer Tools for Visual Studio 2012 SharePoint 2013 Preview Office365 for the SharePoint 2013 preview SharePoint Designer 2013 Download: Microsoft Office 2013 Preview Language Pack Try Office

  • Microsoft ReportViewer SetParameters continuous refresh issue

    - by Ilya Verbitskiy
    Originally posted on: http://geekswithblogs.net/ilich/archive/2013/10/16/microsoft-reportviewer-setparameters-continuous-refresh-issue.aspxI am a big fun of using ASP.NET MVC for building web-applications. It allows us to create simple, robust and testable solutions. However, .NET world is not perfect. There is tons of code written in ASP.NET web-forms. You cannot simply ignore it, even if you want to. Sometimes ASP.NET web-forms controls bring us non-obvious issues. The good example is Microsoft ReportViewer control. I have an example for you. 1: <%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %> 2: <%@ Register Assembly="Microsoft.ReportViewer.WebForms, Version=11.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91" Namespace="Microsoft.Reporting.WebForms" TagPrefix="rsweb" %> 3:   4: <!DOCTYPE html> 5:   6: <html xmlns="http://www.w3.org/1999/xhtml"> 7: <head runat="server"> 8: <title>Report Viewer Continiuse Resfresh Issue Example</title> 9: </head> 10: <body> 11: <form id="form1" runat="server"> 12: <div> 13: <asp:ScriptManager runat="server"></asp:ScriptManager> 14: <rsweb:ReportViewer ID="_reportViewer" runat="server" Width="100%" Height="100%"></rsweb:ReportViewer> 15: </div> 16: </form> 17: </body> 18: </html>   The back-end code is simple as well. I want to show a report with some parameters to a user. 1: protected void Page_Load(object sender, EventArgs e) 2: { 3: _reportViewer.ProcessingMode = ProcessingMode.Remote; 4: _reportViewer.ShowParameterPrompts = false; 5:   6: var serverReport = _reportViewer.ServerReport; 7: serverReport.ReportServerUrl = new Uri("http://localhost/ReportServer_SQLEXPRESS"); 8: serverReport.ReportPath = "/Reports/TestReport"; 9:   10: var reportParameter1 = new ReportParameter("Parameter1"); 11: reportParameter1.Values.Add("Hello World!"); 12:   13: var reportParameter2 = new ReportParameter("Parameter2"); 14: reportParameter2.Values.Add("10/16/2013"); 15:   16: var reportParameter3 = new ReportParameter("Parameter3"); 17: reportParameter3.Values.Add("10"); 18:   19: serverReport.SetParameters(new[] { reportParameter1, reportParameter2, reportParameter3 }); 20: }   I set ShowParametersPrompts to false because I do not want user to refine the search. It looks good until you run the report. The report will refresh itself all the time. The problem caused by ServerReport.SetParameters method in Page_Load. The method cause ReportViewer control to execute the report on the NEXT post back. That is why the page has continuous post-backs. The fix is very simple: do nothing if Page_Load method executed during post-back. 1: protected void Page_Load(object sender, EventArgs e) 2: { 3: if (IsPostBack) 4: { 5: return; 6: } 7:   8: _reportViewer.ProcessingMode = ProcessingMode.Remote; 9: _reportViewer.ShowParameterPrompts = false; 10:   11: var serverReport = _reportViewer.ServerReport; 12: serverReport.ReportServerUrl = new Uri("http://localhost/ReportServer_SQLEXPRESS"); 13: serverReport.ReportPath = "/Reports/TestReport"; 14:   15: var reportParameter1 = new ReportParameter("Parameter1"); 16: reportParameter1.Values.Add("Hello World!"); 17:   18: var reportParameter2 = new ReportParameter("Parameter2"); 19: reportParameter2.Values.Add("10/16/2013"); 20:   21: var reportParameter3 = new ReportParameter("Parameter3"); 22: reportParameter3.Values.Add("10"); 23:   24: serverReport.SetParameters(new[] { reportParameter1, reportParameter2, reportParameter3 }); 25: } You can download sample code from GitHub - https://github.com/ilich/Examples/tree/master/ReportViewerContinuousRefresh

  • WEB203 &ndash; Jump into Silverlight!&hellip; and Become Effective Immediately with Tim Huckaby, Fou

    - by Robert Burger
    Getting ready for the good stuff. Definitely wish there were more Silverlight and WCF RIA sessions, but this is a start.  Was lucky to get a coveted power-enabled seat.  Luckily, due to my trustily slow Verizon data card, I can get these notes out amidst a total Internet outage here.  This is the second breakout session of the day, and is by far standing-room only.  I stepped out before the session started to get a cool Diet COKE and wouldn’t have gotten back in if I didn’t already have a seat. Tim says this is an intro session and that he’s been begging for intro sessions at TechEd for years and that by looking at this audience, he thinks the demand is there.  Admittedly, I didn’t know this was an intro session, or I might have gone elsewhere.  But, it was the very first Silverlight session, so I had to be here. Tim says he will be providing a very good comprehensive reference application at the end of the presentation.  He has just demoed it, and it is a full CRUD-based Sales Manager application based on…  AdventureWorks! Session Agenda What it is / How to get started Declarative Programming Layout and Controls, Events and Commands Working with Data Adding Style to Your Application   Silverlight…  “WPF Light” Why is the download 4.2MB?  Because the direct competitor is a 4.2MB download.  There is no technical reason it is not the entire framework.  It is purely to “be competitive”.   Getting Started Get all of the following downloads from www.silverlight.net/getstarted Install VS2010 or Visual Web Developer Express 2010 Install Silverlight 4 Tools for VS2010 Install Expression Blend 4 Install the Silverlight 4 Toolkit   Reference Application Features Uses MVVM pattern – a way to move data access code that would normally be inline within the UI and placing it in nice data access libraries Images loaded dynamically from the database, converting GIF to PNG because Silverlight does not support GIF. LINQ to SQL is the data access model WCF is the data provider and is using binary message encoding   Declarative Programming XAML replaces code for UI representation Attributes control Layout and Style Event handlers wired-up in XAML Declarative Data Binding   Layout Overview Content rendering flows inside of parent Fixed positioning (Canvas) is seldom used Panels are used to house content Margins and Padding over fixed size   Panels StackPanel – Arranges child elements into a single line oriented horizontally or vertically Grid – A flexible grid are that consists of rows and columns Canvas – An are where positions are specifically fixed WrapPanel (in Toolkit) – Positions child elements in sequential position left to right and top to bottom. DockPanel (in Toolkit) – Positions child controls within a dockable area   Positioning Horizontal and Vertical Alignment Margin – Separates an element from neighboring elements Padding – Enlarges the effective size of an element by a thickness   Controls Overview Not all controls created equal Silverlight, as a subset of WPF, so many WPF controls do not exist in the core Siverlight release Silverlight Toolkit continues to add controls, but are released in different quality bands Plenty of good 3rd party controls to fill the gaps Windows Phone 7 is to have 95% of controls available in Silverlight Core and Toolkit.   Events and Commands Standard .NET Events Routed Events Commands – based on the ICommand interface – logical action that can be invoked in several ways   Adding Style to Your Application Resource Dictionaries – Contains a hash table of key/value pairs.  Silverlight can only use Static Resources whereas WPF can also use Dynamic Resources Visual State Manager Silverlight 4 supports Implicit styles ResourceDictionary.MergedDictionaries combines many different file-based resources   Downloads

  • How to create managed properties at site collection level in SharePoint2013

    - by ybbest
    In SharePoint2013, you can create managed properties at site collection. Today, I’d like to show you how to do so through PowerShell. 1. Define your managed properties and crawled properties and managed property Type in an external csv file. PowerShell script will read this file and create the managed and the mapping. 2. As you can see I also defined variant Type, this is because you need the variant type to create the crawled property. In order to have the crawled properties, you need to do a full crawl and also make sure you have data populated for your custom column. However, if you do not want to a full crawl to create those crawled properties, you can create them yourself by using the PowerShell; however you need to make sure the crawled properties you created have the same name if created by a full crawl. Managed properties type: Text = 1 Integer = 2 Decimal = 3 DateTime = 4 YesNo = 5 Binary = 6 Variant Type: Text = 31 Integer = 20 Decimal = 5 DateTime = 64 YesNo = 11 3. You can use the following script to create your managed properties at site collection level, the differences for creating managed property at site collection level is to pass in the site collection id. param( [string] $siteUrl="http://SP2013/", [string] $searchAppName = "Search Service Application", $ManagedPropertiesList=(IMPORT-CSV ".\ManagedProperties.csv") ) Add-PSSnapin Microsoft.SharePoint.PowerShell -ErrorAction SilentlyContinue $searchapp = $null function AppendLog { param ([string] $msg, [string] $msgColor) $currentDateTime = Get-Date $msg = $msg + " --- " + $currentDateTime if (!($logOnly -eq $True)) { # write to console Write-Host -f $msgColor $msg } # write to log file Add-Content $logFilePath $msg } $scriptPath = Split-Path $myInvocation.MyCommand.Path $logFilePath = $scriptPath + "\CreateManagedProperties_Log.txt" function CreateRefiner {param ([string] $crawledName, [string] $managedPropertyName, [Int32] $variantType, [Int32] $managedPropertyType,[System.GUID] $siteID) $cat = Get-SPEnterpriseSearchMetadataCategory –Identity SharePoint -SearchApplication $searchapp $crawledproperty = Get-SPEnterpriseSearchMetadataCrawledProperty -Name $crawledName -SearchApplication $searchapp -SiteCollection $siteID if($crawledproperty -eq $null) { Write-Host AppendLog "Creating Crawled Property for $managedPropertyName" Yellow $crawledproperty = New-SPEnterpriseSearchMetadataCrawledProperty -SearchApplication $searchapp -VariantType $variantType -SiteCollection $siteID -Category $cat -PropSet "00130329-0000-0130-c000-000000131346" -Name $crawledName -IsNameEnum $false } $managedproperty = Get-SPEnterpriseSearchMetadataManagedProperty -Identity $managedPropertyName -SearchApplication $searchapp -SiteCollection $siteID -ErrorAction SilentlyContinue if($managedproperty -eq $null) { Write-Host AppendLog "Creating Managed Property for $managedPropertyName" Yellow $managedproperty = New-SPEnterpriseSearchMetadataManagedProperty -Name $managedPropertyName -Type $managedPropertyType -SiteCollection $siteID -SearchApplication $searchapp -Queryable:$true -Retrievable:$true -FullTextQueriable:$true -RemoveDuplicates:$false -RespectPriority:$true -IncludeInMd5:$true } $mappedProperty = $crawledproperty.GetMappedManagedProperties() | ?{$_.Name -eq $managedProperty.Name } if($mappedProperty -eq $null) { Write-Host AppendLog "Creating Crawled -> Managed Property mapping for $managedPropertyName" Yellow New-SPEnterpriseSearchMetadataMapping -CrawledProperty $crawledproperty -ManagedProperty $managedproperty -SearchApplication $searchapp -SiteCollection $siteID } $mappedProperty = $crawledproperty.GetMappedManagedProperties() | ?{$_.Name -eq $managedProperty.Name } #Get-FASTSearchMetadataCrawledPropertyMapping -ManagedProperty $managedproperty } $searchapp = Get-SPEnterpriseSearchServiceApplication $searchAppName $site= Get-SPSite $siteUrl $siteId=$site.id Write-Host "Start creating Managed properties" $i = 1 FOREACH ($property in $ManagedPropertiesList) { $propertyName=$property.managedPropertyName $crawledName=$property.crawledName $managedPropertyType=$property.managedPropertyType $variantType=$property.variantType Write-Host $managedPropertyType Write-Host "Processing managed property $propertyName $($i)..." $i++ CreateRefiner $crawledName $propertyName $variantType $managedPropertyType $siteId Write-Host "Managed property created " $propertyName } Key Concepts Crawled Properties: Crawled properties are discovered by the search index service component when crawling content. Managed Properties: Properties that are part of the Search user experience, which means they are available for search results, advanced search, and so on, are managed properties. Mapping Crawled Properties to Managed Properties: To make a crawled property available for the Search experience—to make it available for Search queries and display it in Advanced Search and search results—you must map it to a managed property.
