  • Visual Studio 2010 Productivity Power Tool Extensions

    - by ScottGu
    Last month I blogged about the Extension Manager that is built-into VS 2010 – as well as about a cool VS 2010 PowerCommands extension that provides some extra features for Visual Studio.  The Visual Studio 2010 Extension Manager provides an easy way for developers to quickly find and install extensions and plugins that enhance the built-in functionality to VS 2010. New VS 2010 Productivity Power Tools Release Earlier this week Jason Zander announced the availability of a new VS 2010 Productivity Power Tools release that includes a bunch of great new VS 2010 extensions that provide a bunch of cool new functionality for you to take advantage of.  You can download and install the release for free here.  Some of the code editor improvements it provides include: Entire Line Highlighting: Makes it easier to track cursor location within the editor Entire Line Selection: Triple Clicking a line in the code editor now selects the entire line (like with MS Word) Code Block Movement: Use Alt+Up/Down Arrow now moves selected code blocks up/down in the editor Consistent Tabs vs. Spaces: Ensure consistent tab vs. space usage across your projects Colorized Parameters: It is now easier to see/identify method parameters Column Guide: You can now add vertical column guidelines to help with text alignment and sizes Align assignments: Makes it easier to line-up multiple variable assignments within your code HTML Clipboard Support: Copy/paste code from VS into an HTML buffer (useful for blogging!) Ctrl + Click Go to Definition: You can now hold down the Ctrl key and click a type to go to its definition It also includes several tab management improvements for managing document tabs within the IDE: Show Close Button in Tab Well: Shows a close button in document well for the active tab (like VS 2008 did) Colored Tabs: You can now select the color of each document tab by project or by regex Pinned Tabs: Enables you to pin tabs to keep them always visible and available Vertical Tabs: You can now show document tabs vertically to fit more tabs than normal Remove Tabs by Usage Order: Better behavior when adding new tabs and one needs to be hidden for space reasons Sort Tabs by Project: Tabs can be sorted by project they belong to, keeping them grouped together Sort Tabs Alphabetically: Tabs can be sorted alphabetically And last – but not least – it includes a new and improved “Add Reference” dialog: This new Add Reference dialog caches assembly information – which means it loads within a second or two (note: the very first time it still loads assembly data – but it then caches it and makes it fast afterwards). The new Add Reference dialog also now includes searching support – making it easier to find the assembly you are looking for. You can read more about all of the above improvements in Jason’s blog post about the release. New Visualization and Modeling Feature Pack Release Earlier this week we also shipped a new feature pack that adds additional modeling and code visualization features to VS 2010 Ultimate.  You can download it here. The Visualization and Modeling Feature Pack includes a bunch of great new capabilities including: Web Site Visualization: New support for generating a DGML visualization for ASP.NET projects C/C++ Native Code Visualization: New support for generating DGML diagrams for C/C++ projects Generate Code from UML Class Diagrams: You can now generate code from your UML diagrams Create UML Class Diagrams from Code: Create UML diagrams from existing code bases Import UML from XML: Import UML class, sequence, and use case elements from XMI 2.1 files Custom Validation Layer Rules: Write custom code to create, modify, and validate layer diagrams Jason’s blog post covers more about these features as well. Hope this helps, Scott P.S. In addition to blogging, I am also now using Twitter for quick updates and to share links. Follow me at: twitter.com/scottgu

  • C# Proposal: Compile Time Static Checking Of Dynamic Objects

    - by Paulo Morgado
    C# 4.0 introduces a new type: dynamic. dynamic is a static type that bypasses static type checking. This new type comes in very handy to work with: The new languages from the dynamic language runtime. HTML Document Object Model (DOM). COM objects. Duck typing … Because static type checking is bypassed, this: dynamic dynamicValue = GetValue(); dynamicValue.Method(); is equivalent to this: object objectValue = GetValue(); objectValue .GetType() .InvokeMember( "Method", BindingFlags.InvokeMethod, null, objectValue, null); Apart from caching the call site behind the scenes and some dynamic resolution, dynamic only looks better. Any typing error will only be caught at run time. In fact, if I’m writing the code, I know the contract of what I’m calling. Wouldn’t it be nice to have the compiler do some static type checking on the interactions with these dynamic objects? Imagine that the dynamic object that I’m retrieving from the GetValue method, besides the parameterless method Method also has a string read-only Property property. This means that, from the point of view of the code I’m writing, the contract that the dynamic object returned by GetValue implements is: string Property { get; } void Method(); Since it’s a well defined contract, I could write an interface to represent it: interface IValue { string Property { get; } void Method(); } If dynamic allowed to specify the contract in the form of dynamic(contract), I could write this: dynamic(IValue) dynamicValue = GetValue(); dynamicValue.Method(); This doesn’t mean that the value returned by GetValue has to implement the IValue interface. It just enables the compiler to verify that dynamicValue.Method() is a valid use of dynamicValue and dynamicValue.OtherMethod() isn’t. If the IValue interface already existed for any other reason, this would be fine. But having a type added to an assembly just for compile time usage doesn’t seem right. So, dynamic could be another type construct. Something like this: dynamic DValue { string Property { get; } void Method(); } The code could now be written like this; DValue dynamicValue = GetValue(); dynamicValue.Method(); The compiler would never generate any IL or metadata for this new type construct. It would only thee used for compile type static checking of dynamic objects. As a consequence, it makes no sense to have public accessibility, so it would not be allowed. Once again, if the IValue interface (or any other type definition) already exists, it can be used in the dynamic type definition: dynamic DValue : IValue, IEnumerable, SomeClass { string Property { get; } void Method(); } Another added benefit would be IntelliSense. I’ve been getting mixed reactions to this proposal. What do you think? Would this be useful?

  • SQL SERVER – What is a Technology Evangelist?

    - by pinaldave
    When you hear that someone is an “evangelist” the first thing that might pop into your mind is the Christian church.  In fact, the term did come from Christianity, and basically means someone who spreads the news about their faith.  In the technology world, the same definition is true. Technology evangelists are individuals who, professionally or in their spare time, spread the news about the latest new products.  Sounds like a salesperson, right?  No they are absolutely different. Salespeople also keep up to date with a large number of people, and like to convince others to buy their product – and some will go to any lengths to sell!  An evangelist, on the other hand, is brutally honest about the product, even if sometimes it means not making a sale.  An evangelist is out there to tell the TRUTH.  A salesperson needs to make sales. An Evangelist offers a Solution independent of Technology used – a Salesperson offers Particular Technology. With this definition in mind, you can probably think of a few technology evangelists you already know.  Maybe it’s a relative or a neighbor, someone who loves keeping up with the latest trends and is always willing to tell you about them if you ask even the simplest question.  And, in fact, they probably are evangelists and don’t even know it.  For a long time, the work of technology evangelism was in the hands of community and community technology leaders. Luckily now various organizations have understood the importance of the community and helping community to reach their goals. This has lead them to create role of “Technology Evangelists”. Let me talk about one of the most famous Evangelist of the SQL Server technology. Technology Evangelist only belongs to technology and above any country, race, location or any other thing. They are dedicated to the technology. Vinod Kumar is such a man, who have given a lot to community. For years he was a Technology Evangelist for Microsoft, and maintained a blog that was dedicated to spreading his enthusiasm for his favorite products.  He is one of the most respected Evangelists in the field, and has done a lot of work to define the job for other professionals. Vinod’s career has since progressed to the Microsoft Technology Center (read his post), but he is continuing to be a strong presence in the evangelism community.  I have a lot of respect for Vinod.  He has done a lot for the community and technology evangelism.  Everybody has dream to serve community the way he does, and he is a great role model for evangelists everywhere. On his blog, Vinod created one of the best descriptions of a Technology Evangelist.  It defined the position and also made the distinction between evangelist and salesperson extremely clear.  I will include the highlights of that list here, because no one can say it better than Vinod: Bundle of energy – Passion is their middle name Wonderful Story tellers Empathy, Trust, Loyalty, Openness, Accessibility and Warmth Technology Enthusiast – Doers Love people, people and more people – Community oriented Unique Style and Leadership qualities !!! Self-Confident, Self-Motivated but a student (To read the full list, see: Evangelism Beyond Borders with Evangelists) His blog is a must-read for anyone interested in technology evangelism as a career or simply a hobby.  His advice about how to gain an audience and become a trusted advisor is the best in the business. I think there is an evangelist in everyone. I, too, consider myself a technology evangelist.  Regular readers of this blog will recognize that I am dedicated to bringing information to the masses, and that I pride myself on being both brutally and honest and giving every product fair consideration. I think there is no better way of saying following subject. “Once an Evangelist – Always an Evangelist!” Reference: Pinal Dave (http://blog.SQLAuthority.com)     Filed under: About Me, Database, MVP, Pinal Dave, PostADay, SQL, SQL Authority, SQL Query, SQL Server, SQL Tips and Tricks, SQLAuthority News, T SQL, Technology Tagged: Evangelist

  • 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.

  • Changing the action of a hyperlink in a Silverlight RichTextArea

    - by Marc Schluper
    The title of this post could also have been "Move over Hyperlink, here comes Actionlink" or "Creating interactive text in Silverlight." But alas, there can be only one. Hyperlinks are very useful. However, they are also limited because their action is fixed: browse to a URL. This may have been adequate at the start of the Internet, but nowadays, in web applications, the one thing we do not want to happen is a complete change of context. In applications we typically like a hyperlink selection to initiate an action that updates a part of the screen. For instance, if my application has a map displayed with some text next to it, the map would react to a selection of a hyperlink in the text, e.g. by zooming in on a location and displaying additional locational information in a popup. In this way, the text becomes interactive text. It is quite common that one company creates and maintains websites for many client companies. To keep maintenance cost low, it is important that the content of these websites can be updated by the client companies themselves, without the need to involve a software engineer. To accommodate this scenario, we want the author of the interactive text to configure all hyperlinks (without writing any code). In a Silverlight RichTextArea, the default action of a Hyperlink is the same as a traditional hyperlink, but it can be changed: if the Command property has a value then upon a click event this command is called with the value of the CommandParameter as parameter. How can we let the author of the text specify a command for each hyperlink in the text, and how can we let an application react properly to a hyperlink selection event? We are talking about any command here. Obviously, the application would recognize only a specific set of commands, with well defined parameters, but the approach we take here is generic in the sense that it pertains to the RichTextArea and any command. So what do we require? We wish that: As a text author, I can configure the action of a hyperlink in a (rich) text without writing code; As a text author, I can persist the action of a hyperlink with the text; As a reader of persisted text, I can click a hyperlink and the configured action will happen; As an application developer, I can configure a control to use my application specific commands. In an excellent introduction to the RichTextArea, John Papa shows (among other things) how to persist a text created using this control. To meet our requirements, we can create a subclass of RichTextArea that uses John's code and allows plugging in two command specific components: one to prompt for a command definition, and one to execute the command. Since both of these plugins are application specific, our RichTextArea subclass should not assume anything about them except their interface. public interface IDefineCommand { void Prompt(string content, // the link content Action<string, object> callback); // the method called to convey the link definition } public interface IPerformCommand : ICommand {} The IDefineCommand plugin receives the content of the link (the text visible to the reader) and displays some kind of control that allows the author to define the link. When that's done, this (possibly changed) content string is conveyed back to the RichTextArea, together with an object that defines the command to execute when the link is clicked by the reader of the published text. The IPerformCommand plugin simply implements System.Windows.Input.ICommand. Let's use MEF to load the proper plugins. In the example solution there is a project that contains rudimentary implementations of these. The IDefineCommand plugin simply prompts for a command string (cf. a command line or query string), and the IPerformCommand plugin displays a MessageBox showing this command string. An actual application using this extended RichTextArea would have its own set of commands, each having their own parameters, and hence would provide more user friendly application specific plugins. Nonetheless, in any case a command can be persisted as a string and hence the two interfaces defined above suffice. For a Visual Studio 2010 solution, see my article on The Code Project.

  • SharePoint 2010 Hosting :: SharePoint 2010 Custom Web Template

    - by mbridge
    SharePoint 2010 offers some changes and additions to the SharePoint 2007 approach. Site definitions and publishing providers remain largely the same, but site templates created from the SharePoint UI or SharePoint Designer are now saved to a .WSP file, the same solution deployment packaging file format used for deploying custom SharePoint solutions. Site Templates saved to a .WSP solution file can be imported into Visual Studio for additional customization. Introducing the WebTemplate Feature Element The WebTemplate element, introduced in SharePoint 2010, allows site templates to be defined and deployed as a Feature as part of a solution package. A WebTemplate element feature can be used to deploy site templates in either a Farm or Sandbox solution - without modification. If deployed as a Farm feature and solution, site templates will appear in the site collection provisioning page in Central Administration and can be used to provision new site collections, or within a Site Collection to create sub-sites. If deployed as a Site feature and Sandbox solution, site templates will appear within the site collection to support creating a root site or sub-sites. Creating a new WebTemplate Feature in Visual Studio 2010 In addition to supporting the ability to save and import Site Templates created from the SharePoint UI into Visual Studio for customization, it can also be used to create new site templates from scratch. In the following sample we will walk through how to create a new WebTemplate solution based on  a customized version of the out-of-box Blank Site. 1. Create a new Empty SharePoint Project in Visual Studio 2010. 2. Add a new Empty Element to the project. we like to create folders for each type of element in our solution, so in our sample, we have created a Web Templates folder, and then added the BLANKENT element. NOTE: The Elements folder MUST share the same name as the WebTemplate name property. 3. Open the empty Elements.xml and add the <WebTemplate /> element block. 4. Copy the default.aspx and ONET.XML files from the STS site definition location at 14\TEMPLATES\Site Templates\STS. We will customize the ONET.XML in the next section. Open the properties for each file and set the Deployment Type to ElementFile. This ensures the files are deployed with the Element when included in a Feature. 5. By default a new feature is added to the solution for you automatically when a new element is added to the solution. Rename and edit the feature as appropriate. Select Farm for the scope to deploy the WebTemplate to the entire farm, or Site for a sandboxed solution. Customize the ONET.XML At this point, you have a working WebTemplate solution that will deploy the identical site to the out-of-box Blank Site, however the ONET.XML supporting the STS site definition contains 3 configurations – essentially 3 separate site templates and can be simplified before customizing. In the following sample, we have trimmed the ONET.XML to the essentials for a single Site Template, and added references to the <SiteFeatures /> and <WebFeatures /> elements to include the SharePoint Standard and Enterprise features. We have left the top-level navigation bar, and the default page module intact, but removed all other extraneous markup.

  • Part 15: Fail a build based on the exit code of a console application

    In the series the following parts have been published Part 1: Introduction Part 2: Add arguments and variables Part 3: Use more complex arguments Part 4: Create your own activity Part 5: Increase AssemblyVersion Part 6: Use custom type for an argument Part 7: How is the custom assembly found Part 8: Send information to the build log Part 9: Impersonate activities (run under other credentials) Part 10: Include Version Number in the Build Number Part 11: Speed up opening my build process template Part 12: How to debug my custom activities Part 13: Get control over the Build Output Part 14: Execute a PowerShell script Part 15: Fail a build based on the exit code of a console application When you have a Console Application or a batch file that has errors, the exitcode is set to another value then 0. You would expect that the build would see this and report an error. This is not true however. First we setup the scenario. Add a ConsoleApplication project to your solution you are building. In the Main function set the ExitCode to 1     class Program    {        static void Main(string[] args)        {            Console.WriteLine("This is an error in the script.");            Environment.ExitCode = 1;        }    } Checkin the code. You can choose to include this Console Application in the build or you can decide to add the exe to source control Now modify the Build Process Template CustomTemplate.xaml Add an argument ErrornousScript Scroll down beneath the TryCatch activity called “Try Compile, Test, and Associate Changesets and Work Items” Add an Sequence activity to the template In the Sequence, add a ConvertWorkspaceItem and an InvokeProcess activity (see Part 14: Execute a PowerShell script  for more detailed steps) In the FileName property of the InvokeProcess use the ErrornousScript so the ConsoleApplication will be called. Modify the build definition and make sure that the ErrornousScript is executing the exe that is setting the ExitCode to 1. You have now setup a build definition that will execute the errornous Console Application. When you run it, you will see that the build succeeds. This is not what you want! To solve this, you can make use of the Result property on the InvokeProcess activity. So lets change our Build Process Template. Add the new variables (scoped to the sequence where you run the Console Application) called ExitCode (type = Int32) and ErrorMessage Click on the InvokeProcess activity and change the Result property to ExitCode In the Handle Standard Output of the InvokeProcess add a Sequence activity In the Sequence activity, add an Assign primitive. Set the following properties: To = ErrorMessage Value = If(Not String.IsNullOrEmpty(ErrorMessage), Environment.NewLine + ErrorMessage, "") + stdOutput And add the default BuildMessage to the sequence that outputs the stdOutput Add beneath the InvokeProcess activity and If activity with the condition ExitCode <> 0 In the Then section add a Throw activity and set the Exception property to New Exception(ErrorMessage) The complete workflow looks now like When you now check in the Build Process Template and run the build, you get the following result And that is exactly what we want.   You can download the full solution at BuildProcess.zip. It will include the sources of every part and will continue to evolve.

  • Wireless internet is connected to an open network but has no internet

    - by Joshua Reeder
    I just installed Ubuntu on my laptop yesterday and it connected to the wireless fine. Then I took it to school, put it on their wired connection, downloaded some stuff, and now the wireless doesn't work. At first it would detect networks, but not connect. I restarted it and now it can connect, but it acts like it doesn't have internet in the browser. Wired connection still works fine on it.

  • Detecting Process Shutdown/Startup Events through ActivationAgents

    - by Ramkumar Menon
    @10g - This post is motivated by one of my close friends and colleague - who wanted to proactively know when a BPEL process shuts down/re-activates. This typically happens when you have a BPEL Process that has an inbound polling adapter, when the adapter loses connectivity to the source system. Or whatever causes it. One valuable suggestion came in from one of my colleagues - he suggested I write my own ActivationAgent to do the job. Well, it really worked. Here is a sample ActivationAgent that you can use. There are few methods you need to override from BaseActivationAgent, and you are on your way to receiving notifications/what not, whenever the shutdown/startup events occur. In the example below, I am retrieving the emailAddress property [that is specified in your bpel.xml activationAgent section] and use that to send out an email notification on the activation agent initialization. You could choose to do different things. But bottomline is that you can use the below-mentioned API to access the very same properties that you specify in the bpel.xml. package com.adapter.custom.activation; import com.collaxa.cube.activation.BaseActivationAgent; import com.collaxa.cube.engine.ICubeContext; import com.oracle.bpel.client.BPELProcessId; import java.util.Date; import java.util.Properties; public class LifecycleManagerActivationAgent extends BaseActivationAgent { public BPELProcessId getBPELProcessId() { return super.getBPELProcessId(); } private void handleInit() throws Exception { //Write initialization code here System.err.println("Entered initialization code...."); //e.g. String emailAddress = getActivationAgentDescriptor().getPropertyValue(emailAddress); //send an email sendEmail(emailAddress); } private void handleLoad() throws Exception { //Write load code here System.err.println("Entered load code...."); } private void handleUnload() throws Exception { //Write unload code here System.err.println("Entered unload code...."); } private void handleUninit() throws Exception { //Write uninitialization code here System.err.println("Entered uninitialization code...."); } public void init(ICubeContext icubecontext) throws Exception { super.init(icubecontext); System.err.println("Initializing LifecycleManager Activation Agent ....."); handleInit(); } public void unload(ICubeContext icubecontext) throws Exception { super.unload(icubecontext); System.err.println("Unloading LifecycleManager Activation Agent ....."); handleUnload(); } public void uninit(ICubeContext icubecontext) throws Exception{ super.uninit(icubecontext); System.err.println("Uninitializing LifecycleManager Activation Agent ....."); handleUninit(); } public String getName() { return "Lifecyclemanageractivationagent"; } public void onStateChanged(int i, ICubeContext iCubeContext) { } public void onLifeCycleChanged(int i, ICubeContext iCubeContext) { } public void onUndeployed(ICubeContext iCubeContext) { } public void onServerShutdown() { } } Once you compile this code, generate a jar file and ensure you add it to the server startup classpath. The library is ready for use after the server restarts. To use this activationAgent, add an additional activationAgent entry in the bpel.xml for the BPEL Process that you wish to monitor. After you deploy the process, the ActivationAgent object will be called back whenever the events mentioned in the overridden methods are raised. [init(), load(), unload(), uninit()]. Subsequently, your custom code is executed. Sample bpel.xml illustrating activationAgent definition and property definition. <?xml version="1.0" encoding="UTF-8"? <BPELSuitcase timestamp="1291943469921" revision="1.0" <BPELProcess wsdlPort="{http://xmlns.oracle.com/BPELTest}BPELTestPort" src="BPELTest.bpel" wsdlService="{http://xmlns.oracle.com/BPELTest}BPELTest" id="BPELTest" <partnerLinkBindings <partnerLinkBinding name="client" <property name="wsdlLocation"BPELTest.wsdl</property </partnerLinkBinding <partnerLinkBinding name="test" <property name="wsdlLocation"test.wsdl</property </partnerLinkBinding </partnerLinkBindings <activationAgents <activationAgent className="oracle.tip.adapter.fw.agent.jca.JCAActivationAgent" partnerLink="test" <property name="portType"Read_ptt</property </activationAgent <activationAgent className="com.oracle.bpel.activation.LifecycleManagerActivationAgent" partnerLink="test" <property name="emailAddress"[email protected]</property </activationAgent </activationAgents </BPELProcess </BPELSuitcase em

  • Oracle Tutor: XPDL conversion (and why you should care)

    - by mary.keane
    You may have noticed that the Oracle Business Process Converter feature in Tutor 14 supports "XPDL" conversion to Oracle Business Process Analysis Suite (BPA), Oracle Business Process Management Suite (BPM), and Oracle Tutor, and you may have briefly wondered "what is XPDL?" before you moved on to the Visio import feature (a very popular feature in Tutor 14). This posting is for those who do not yet understand (or care) about XPDL and process modeling. Many of us (and I'm including myself) have spent years working in the process definition arena: we've written procedures, designed systems and software to help others write procedures, and have been responsible for embedding policies and procedures into training material for employees. We've worked with tools such as Oracle Tutor, Microsoft Visio, Microsoft Word, and UPK. Most of us have never worked with "modeling tools" before, and we certainly never had to understand BPMN. It's a brave new world in this arena, and companies desperately need people with policy and procedural system expertise to be able to work with system analysts so there is a seamless transfer of knowledge from IT to employees. When working with applications, a picture is worth a thousand words, so eventually you're going to need to understand and be able to work with business process models. XPDL is an acronym for XML Process Definition Language, and it is an interchange format for business process models. It allows you to take a BPMN model that was developed in one workflow application such as BizAgi and import it into another workflow application or a true BPMN management system such as Oracle BPM. Specifically, the XPDL format contains the graphical information of a model as well as any executable information. By using a common format, models can be moved from a basic modeling application used by business owners to applications used by system architects. Over 80 applications support the XPDL format, including MetaStorm ProVision, BEA ALBPM, BizAgi, and Tibco. I mention these applications because we have provided XSLT mapping files specifically for these vendors. Oracle Business Process Converter was designed with user extensibility in mind, and thus users can add their own XML files so that additional XPDL models from other vendors can be converted to BPM, BPA, and Oracle Tutor. Instructions on how to add your own files can be found in Appendix 4 of the Oracle Business Converter manual. Let's take a visual look at how this works. Here is an example of a model devloped in BizAgi: This model can be created by the average business user without a large learning curve, and it's a good start for the system analyst who will be adding web services as well as for the business manager who manages the process described in the model. By exporting this model as XPDL, the information can be converted into Oracle BPA and Oracle BPM as well as converted to Oracle Tutor to become the framework for a procedure. Through this conversion feature, one graphic illustration of a business process can be used by a system analyst, business analyst, business manager, and employee, as seen below. Model Converted to Tutor Procedure Below is the task section of the procedure after conversion from an XPDL file. Model converted to BPA Model converted to BPM End users still want step by step instructions on how to perform their jobs, so procedures (Oracle Tutor) and application simulations (UPK) are still a critical piece of the solution. But IT professionals need graphic descriptions of how the applications work, regardless of whether there are any tasks involving humans. Now there is a way to convert procedures (Oracle Tutor docx files) and basic models (XPDL files) so that business managers and system analysts can share process information. References Wikipedia XPDL. Workflow Management Coalition, XPDL Support and Resources Oracle Business Process Converter manual, Oracle Tutor 14 Oracle Business Process Management 11g If you have any XPDL conversion stories to share, we'd love to hear from you. Best wishes for the coming new year, Mary Keane, Senior Development Manager, Oracle Tutor and BPM

  • Type checking and recursive types (Writing the Y combinator in Haskell/Ocaml)

    - by beta
    When explaining the Y combinator in the context of Haskell, it's usually noted that the straight-forward implementation won't type-check in Haskell because of its recursive type. For example, from Rosettacode [1]: The obvious definition of the Y combinator in Haskell canot be used because it contains an infinite recursive type (a = a -> b). Defining a data type (Mu) allows this recursion to be broken. newtype Mu a = Roll { unroll :: Mu a -> a } fix :: (a -> a) -> a fix = \f -> (\x -> f (unroll x x)) $ Roll (\x -> f (unroll x x)) And indeed, the “obvious” definition does not type check: ?> let fix f g = (\x -> \a -> f (x x) a) (\x -> \a -> f (x x) a) g <interactive>:10:33: Occurs check: cannot construct the infinite type: t2 = t2 -> t0 -> t1 Expected type: t2 -> t0 -> t1 Actual type: (t2 -> t0 -> t1) -> t0 -> t1 In the first argument of `x', namely `x' In the first argument of `f', namely `(x x)' In the expression: f (x x) a <interactive>:10:57: Occurs check: cannot construct the infinite type: t2 = t2 -> t0 -> t1 In the first argument of `x', namely `x' In the first argument of `f', namely `(x x)' In the expression: f (x x) a (0.01 secs, 1033328 bytes) The same limitation exists in Ocaml: utop # let fix f g = (fun x a -> f (x x) a) (fun x a -> f (x x) a) g;; Error: This expression has type 'a -> 'b but an expression was expected of type 'a The type variable 'a occurs inside 'a -> 'b However, in Ocaml, one can allow recursive types by passing in the -rectypes switch: -rectypes Allow arbitrary recursive types during type-checking. By default, only recursive types where the recursion goes through an object type are supported. By using -rectypes, everything works: utop # let fix f g = (fun x a -> f (x x) a) (fun x a -> f (x x) a) g;; val fix : (('a -> 'b) -> 'a -> 'b) -> 'a -> 'b = <fun> utop # let fact_improver partial n = if n = 0 then 1 else n*partial (n-1);; val fact_improver : (int -> int) -> int -> int = <fun> utop # (fix fact_improver) 5;; - : int = 120 Being curious about type systems and type inference, this raises some questions I'm still not able to answer. First, how does the type checker come up with the type t2 = t2 -> t0 -> t1? Having come up with that type, I guess the problem is that the type (t2) refers to itself on the right side? Second, and perhaps most interesting, what is the reason for the Haskell/Ocaml type systems to disallow this? I guess there is a good reason since Ocaml also will not allow it by default even if it can deal with recursive types if given the -rectypes switch. If these are really big topics, I'd appreciate pointers to relevant literature. [1] http://rosettacode.org/wiki/Y_combinator#Haskell

  • How can I fix my keyboard layout?

    - by Scott Severance
    For a long time, I've had my keyboard configured to use the layout currently known as "English (international AltGr dead keys)." I like this layout because without any modifier keys, it's identical to the US English keyboard, but when I hold Right Alt I can get accented letters and other characters not available on a standard US English keyboard. In Oneiric, however, the layout is messed up. Right Alt+N produces "ñ" as expected. And another method works: Right Alt+`, E produces "è", also as expected. But there's no way to type "é", which is probably the accented letter I type the most. I expect Right Alt+A, E to do the trick. But instead of a dead key for the acute accent, it uses a method for combining characters to create the hybrid "´e". This hybrid looks like the proper "é" in some settings, but it isn't the same character and doesn't always work. (For example, in the text input box as I type this, it looks the same as the proper character, but when displayed on the site for all so see, it looks very wrong--at least on my machine.) Ditto for all other characters with an acute accent, though some are available directly as pre-composed characters: For example, Right Alt+I yields "í". How can I change the acute accent on the A key to a proper dead key? Perhaps the more general version of this is: How can I tweak my keyboard layout? Update I just tested this on my other machine, also running Oneiric, but upgraded from previous versions. I have no problems with the second machine. The problem machine was a fresh install of Oneiric, but I kept my old $HOME when I did the fresh install. Clarification Even if an answer doesn't address my specific examples, I would still accept it if it provided enough detail for me to find the layout and tweak it according to my needs. Major Update After working through the information gained through Jim C's and Chascon's helpful replies, I've learned something new: The problem isn't with the layout itself, but with the fact that the selected layout isn't being applied. When I look at the definition in /usr/share/X11/xkb/symbols/us of the layout I've been running for a long time, I found that the definition doesn't match what I get when I type. In addition, the keyboard layout dialog that's supposed to show the current layout looks different from the way the layout is defined in the file I mentioned, and matches what actually happens when I type. Following Jim C's suggestion, I created a new layout in /usr/share/X11/xkb/symbols/us containing some modifications to the layout I want. I can select my layout from the keyboard properties, and I can use in on the console following Chascon's post, but the layout I get when typing is unchanged. Apparently, there's a different layout defined somewhere that's overriding what I've set. Where is that layout hiding? This problem occurs in Unity (3D and 2D), but I was able to get the correct layout set in Xfce. In case it's relevant, this problem has occurred since I installed Oneiric fresh on this machine (though I preserved my $HOME). I don't recall whether this problem occurred before the reinstall. Also, in case it's relevant, I also run iBus so I can type Korean. I have a few difficulties with iBus, but I doubt they're related.

  • Improving Click and Drag with C++

    - by Josh
    I'm currently using SFML 2.0 to develop a game in C++. I have a game sprite class that has a click and drag method. The method works, but there is a slight problem. If the mouse moves too fast, the object the user selected can't keep up and is left behind in the spot where the mouse left its bounds. I will share the class definition and the given function implementation. Definition: class codePeg { protected: FloatRect bounds; CircleShape circle; int xPos, yPos, xDiff, yDiff, once; int xBase, yBase; Vector2i mousePos; Vector2f circlePos; public: void init(RenderWindow& Window); void draw(RenderWindow& Window); void drag(RenderWindow& Window); void setPegPosition(int x, int y); void setPegColor(Color pegColor); void mouseOver(RenderWindow& Window); friend int isPegSelected(void); }; Implementation of the "drag" function: void codePeg::drag(RenderWindow& Window) { mousePos = Mouse::getPosition(Window); circlePos = circle.getPosition(); if(Mouse::isButtonPressed(Mouse::Left)) { if(mousePos.x > xPos && mousePos.y > yPos && mousePos.x - bounds.width < xPos && mousePos.y - bounds.height < yPos) { if(once) { xDiff = mousePos.x - circlePos.x; yDiff = mousePos.y - circlePos.y; once = 0; } xPos = mousePos.x - xDiff; yPos = mousePos.y - yDiff; circle.setPosition(xPos, yPos); } } else { once = 1; xPos = xBase; yPos = yBase; xDiff = 0; yDiff = 0; circle.setPosition(xBase, yBase); } Window.draw(circle); } Like I said, the function works, but to me, the code is very ugly and I think it could be improved and could be more efficient. The only thing I can think of as to why the object cannot keep up with the mouse is that there are too many function calls and/or checks. The user does not really have to mouse the mouse "fast" for it to happen, I would say at an average pace the object is left behind. How can I improve the code so that the object remains with the mouse when it is selected? Any help improving this code or giving advice is greatly appreciated.

  • SQL Saturday and Exploring Data Privacy

    - by Johnm
    I have been highly impressed with the growth of the SQL Saturday phenomenon. It seems that an announcement for a new wonderful event finds its way to my inbox on a daily basis. I have had the opportunity to attend the first of the SQL Saturday's for Tampa, Chicago, Louisville and recently my home town of Indianapolis. It is my hope that there will be many more in my future. This past weekend I had the honor of being selected to speak amid a great line up of speakers at SQL Saturday #82 in Indianapolis. My session topic/title was "Exploring Data Privacy". Below is a brief synopsis of my session: Data Privacy in a Nutshell        - Definition of data privacy        - Examples of personally identifiable data        - Examples of Sensitive data Laws and Stuff        - Various examples of laws, regulations and policies that influence the definition of data privacy        - General rules of thumb that encompasses most laws Your Data Footprint        - Who has personal information about you?        - What are you exchanging data privacy for?        - The amazing resilience of data        - The cost of data loss Weapons of Mass Protection       - Data classification       - Extended properties       - Database Object Schemas       - An extraordinarily brief introduction of encryption       - The amazing data professional  <-the most important point of the entire session! The subject of data privacy is one that is quickly making its way to the forefront of the mind of many data professionals. Somewhere out there someone is storing personally identifiable and other sensitive data about you. In some cases it is kept reasonably secure. In other cases it is kept in total exposure without the consideration of its potential of damage to you. Who has access to it and how is it being used? Are we being unnecessarily required to supply sensitive data in exchange for products and services? These are just a few questions on everyone's mind. As data loss events of grand scale hit the headlines in a more frequent succession, the level of frustration and urgency for a solution increases. I assembled this session with the intent to raise awareness of sensitive data and remind us all that we, data professionals, are the ones who have the greatest impact and influence on how sensitive data is regarded and protected. Mahatma Gandhi once said "Be the change you want to see in the world." This is guidance that I keep near to my heart as I approached this topic of data privacy.

  • Hopping/Tumbling Windows Could Introduce Latency.

    This is a pre-article to one I am going to be writing on adjusting an event’s time and duration to satisfy business process requirements but it is one that I think is really useful when understanding the way that Hopping/Tumbling windows work within StreamInsight.  A Tumbling window is just a special shortcut version of  a Hopping window where the width of the window is equal to the size of the hop Here is the simplest and often used definition for a Hopping Window.  You can find them all here public static CepWindowStream<CepWindow<TPayload>> HoppingWindow<TPayload>(     this CepStream<TPayload> source,     TimeSpan windowSize,     TimeSpan hopSize,     WindowInputPolicy inputPolicy,     HoppingWindowOutputPolicy outputPolicy )   And here is the definition for a Tumbling Window public static CepWindowStream<CepWindow<TPayload>> TumblingWindow<TPayload>(     this CepStream<TPayload> source,     TimeSpan windowSize,     WindowInputPolicy inputPolicy,     HoppingWindowOutputPolicy outputPolicy )   These methods allow you to group events into windows of a temporal size.  It is a really useful and simple feature in StreamInsight.  One of the downsides though is that the windows cannot be flushed until an event in a following window occurs.  This means that you will potentially never see some events or see them with a delay.  Let me explain. Remember that a stream is a potentially unbounded sequence of events. Events in StreamInsight are given a StartTime.  It is this StartTime that is used to calculate into which temporal window an event falls.  It is best practice to assign a timestamp from the source system and not one from the system clock on the processing server.  StreamInsight cannot know when a window is over.  It cannot tell whether you have received all events in the window or whether some events have been delayed which means that StreamInsight cannot flush the stream for you.   Imagine you have events with the following Timestamps 12:10:10 PM 12:10:20 PM 12:10:35 PM 12:10:45 PM 11:59:59 PM And imagine that you have defined a 1 minute Tumbling Window over this stream using the following syntax var HoppingStream = from shift in inputStream.TumblingWindow(TimeSpan.FromMinutes(1),HoppingWindowOutputPolicy.ClipToWindowEnd) select new WindowCountPayload { CountInWindow = (Int32)shift.Count() };   The events between 12:10:10 PM and 12:10:45 PM will not be seen until the event at 11:59:59 PM arrives.  This could be a real problem if you need to react to windows promptly This can always be worked around by using a different design pattern but a lot of the examples I see assume there is a constant, very frequent stream of events resulting in windows always being flushed. Further examples of using windowing in StreamInsight can be found here

  • Squibbly: LibreOffice Integration Framework for the Java Desktop

    - by Geertjan
    Squibbly is a new framework for Java desktop applications that need to integrate with LibreOffice, or more generally, need office features as part of a Java desktop solution that could include, for example, JavaFX components. Here's what it looks like, right now, on Ubuntu 13.04: Why is the framework called Squibbly? Because I needed a unique-ish name, because "squibble" sounds a bit like "scribble" (which is what one does with text documents, etc), and because of the many absurd definitions in the Urban Dictionary for the apparently real word "squibble", e.g., "A name for someone who is squibblish in nature." And, another e.g., "A squibble is a small squabble. A squabble is a little skirmish." But the real reason is the first definition (and definitely not the fourth definition): "Taking a small portion of another persons something, such as a small hit off of a pipe, a bite of food, a sip of a drink, or drag of a cigarette." In other words, I took (or "squibbled") a small portion of LibreOffice, i.e., OfficeBean, and integrated it into a NetBeans Platform application. Now anyone can add new features to it, to do anything they need, such as create a legislative software system as Propylon has done with their own solution on the NetBeans Platform: For me, the starting point was Chuk Munn Lee's similar solution from some years ago. However, he uses reflection a lot in that solution, because he didn't want to bundle the related JARs with the application. I understand that benefit but I find it even more beneficial to not need to require the user to specify the location of the LibreOffice location, since all the necessary JARs and native libraries (currently 32-bit Linux only, by the way) are bundled with the application. Plus, hundreds of lines of reflection code, as in Chuk's solution, is not fun to work with at all. Switching between applications is done like this: It's a work in progress, a proof of concept only. Just the result of a few hours of work to get the basic integration to work. Several problems remain, some of them potentially unsolvable, starting with these, but others will be added here as I identify them: Window management problems. I'd like to let the user have multiple LibreOffice applications and documents open at the same time, each in a new TopComponent. However, I haven't figured out how to do that. Right now, each application is opened into the same TopComponent, replacing the currently open application. I don't know the OfficeBean API well enough, e.g., should a single OfficeBean be shared among multiple TopComponents or should each of them have their own instance of it? Focus problems. When putting the application behind other applications and then switching back to the application, typing text becomes impossible. When closing a TopComponent and reopening it, the content is lost completely. Somehow the loss of focus, and then the return of focus, disables something. No idea how to fix that. The project is checked into this location, which isn't public yet, so you can't access it yet. Once it's publicly available, it would be great to get some code contributions and tweaks, etc. https://java.net/projects/squibbly Here's the source structure, showing especially how the OfficeBean JARs and native libraries (currently for Linux 32-bit only) fit in: Ultimately, would be cool to integrate or share code with http://joeffice.com!

  • Asp.net MVC ModelState.Clear

    - by Mr Grok
    Can anyone give me a succinct definition of the role of ModelState in Asp.net MVC (or a link to one). In particular I need to know in what situations it is necessary or desirable to call ModelState.Clear(). Can anyone give me a succinct definition of the role of ModelState in Asp.net MVC (or a link to one). In particular I need to know in what situations it is necessary or desirable to call ModelState.Clear(). Bit open ended huh... sorry, I think it might help if tell you what I'm acutally doing: I have an Action of Edit on a Controller called "Page". When I first see the form to change the Page's details everything loads up fine (binding to a "MyCmsPage" object). Then I click a button that generates a value for one of the MyCmsPage object's fields (MyCmsPage.SeoTitle). It generates fine and updates the object and I then return the action result with the newly modified page object and expect the relevant textbox (rendered using <%= Html.TextBox("seoTitle", page.SeoTitle)%) to be updated ... but alas it displays the value from the old model that was loaded. I've worked around it by using ModelState.Clear() but I need to know why / how it has worked so I'm not just doing it blindly. PageController: [AcceptVerbs("POST")] public ActionResult Edit(MyCmsPage page, string submitButton) { // add the seoTitle to the current page object page.GenerateSeoTitle(); // why must I do this? ModelState.Clear(); // return the modified page object return View(page); } Aspx: <%@ Page Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<MyCmsPage>" %> .... <div class="c"> <label for="seoTitle"> Seo Title</label> <%= Html.TextBox("seoTitle", page.SeoTitle)%> <input type="submit" value="Generate Seo Title" name="submitButton" /> </div>

  • SPException: Catastrophic failure (Exception from HRESULT: 0x8000FFF (E_UNEXPECTED) in Sharepoint

    - by BeraCim
    I've been trying to programmatically copy custom content type and its custom columns from one web to another for some time now, and I always get different errors or exceptions every time. After yet more tries, I received more strange and cryptic exception from Sharepoint after clicking onto a newly copied custom column in a custom content type. I checked the logs, and this is what I got: Unknown SPRequest erorr occurred. More information: 0x80070002 Unable to locate the xml-definition for FieldName with FieldId 'guid without braces', exception: Microsoft.SharePoint.SPException: Catastrophic failure (Exception from HRESULT: 0x8000FFF (E_UNEXPECTED)) ---> System.Runtime.InteropServices.COMException... ... at Microsoft.SharePoint.Library.SPRequestInternalClass.GetGlobalContentTypeXml(String bstrUrl, Int32 type, UInt 32 lcid, Object varIdBytes...

It failed to find quite a few content type schema. I'm confused with what Sharepoint is trying to do here, and why a simple process of copying a custom content type from one web to another just wouldn't work in contrast to the information found on the web e.g. this. Appreciate any help to get over this problem. Thanks.

  • Asp.net MVC Route class that supports catch-all parameter anywhere in the URL

    - by Robert Koritnik
    the more I think about it the more I believe it's possible to write a custom route that would consume these URL definitions: {var1}/{var2}/{var3} Const/{var1}/{var2} Const1/{var1}/Const2/{var2} {var1}/{var2}/Const as well as having at most one greedy parameter on any position within any of the upper URLs like {*var1}/{var2}/{var3} {var1}/{*var2}/{var3} {var1}/{var2}/{*var3} There is one important constraint. Routes with greedy segment can't have any optional parts. All of them are mandatory. Example This is an exemplary request http://localhost/Show/Topic/SubTopic/SubSubTopic/123/This-is-an-example This is URL route definition {action}/{*topicTree}/{id}/{title} Algorithm Parsing request route inside GetRouteData() should work like this: Split request into segments: Show Topic SubTopic SubSubTopic 123 This-is-an-example Process route URL definition starting from the left and assigning single segment values to parameters (or matching request segment values to static route constant segments). When route segment is defined as greedy, reverse parsing and go to the last segment. Parse route segments one by one backwards (assigning them request values) until you get to the greedy catch-all one again. When you reach the greedy one again, join all remaining request segments (in original order) and assign them to the greedy catch-all route parameter. Questions As far as I can think of this, it could work. But I would like to know: Has anyone already written this so I don't have to (because there are other aspects to parsing as well that I didn't mention (constraints, defaults etc.) Do you see any flaws in this algorithm, because I'm going to have to write it myself if noone has done it so far. I haven't thought about GetVirtuaPath() method at all.

  • SSRS for Sharepoint, Images in a report from a Sharepoint List URL?

    - by James Polhemus
    Greetings Sabios, I have several reports I run successfully where the data comes from a Sharepoint list in the form of an XML dataset. I am however having trouble with one. I have a report that pulls an image file onto the main body of the report. This data too comes from a Sharepoint list in the form of an XML dataset which sends me the URL to the jpeg or bmp or gif... whatever the case may be. I can successfully pull this off in my own Visual Studio IDE. My Local Report Server will render it as well It won't run on my Sharepoint Report Server (My MOSS runs through https while my Shartpoint Report Server is http might this matter?) When I upload it to Sharepoint and run it through the Sharepoint Report Server, I get back EVERYTHING in the report Header and Footer (dataset text and embedded Images) but just a big RED X where the Main Image should be. I have done everything the boards say: A. I made sure the Unattended Execution Account is running on the Reports Server B. I have insured the URL comes back in clean format (else the images wouldn't render locally either and they do) The report logs throw this exception: e ERROR: Throwing Microsoft.ReportingServices.Diagnostics.Utilities.ContainerTypeNotSupportedException: The target location you specified is not supported by the report server. A report definition (.rdl), report model (.smdl), resource, or shared data source (.rsds) file must be located within a library or a folder within it., ; Info: Microsoft.ReportingServices.Diagnostics.Utilities.ContainerTypeNotSupportedException: The target location you specified is not supported by the report server. A report definition (.rdl), report model (.smdl), resource, or shared data source (.rsds) file must be located within a library or a folder within it. Any takers? Even my Sharepoint Administrator can't help me:) James

  • Web application creation in IIS7 via MS.Web.Admin

    - by Jon Ownbey
    I am attempting to create seperate workflow instances as applications in IIS7 using the Microsoft.Web.Administration dll. When it attempts to add the Application to the Site ApplicationsCollection I get a COM error: "Invalid application path\r\n" using (ServerManager manager = new ServerManager()) { var site = manager.Sites.Where(x => x.Name == Properties.Settings.Default.WorkflowWebsiteName).Single(); StringBuilder stringBuilder = new StringBuilder() .Append(m_workflowDefinition.AccountId) .Append("/") .Append(m_workflowDefinition.WorkflowDefinitionId) .Append("/") .Append(m_workflowDefinition.Version) .Append("/"); string virtualPath = stringBuilder.ToString(); string physicalPath = Properties.Settings.Default.ApplicationPoolString + virtualPath.Replace("/", "\\"); if (!Directory.Exists(physicalPath)) Directory.CreateDirectory(physicalPath); //Create the workflow service definition file using (StreamWriter writer = new StreamWriter(Path.Combine(physicalPath, m_workflowDefinition.WorkflowName + WORKFLOW_FILE_EXTENSION))) { writer.Write(m_workflowDefinition.Definition); } //Copy dependencies string dependencyPath = m_workflowDefinition.DependenciesPath; CopyAll(new DirectoryInfo(dependencyPath), new DirectoryInfo(physicalPath)); //Create a new IIS application for the workflow var apps = site.Applications.Where(x => x.Path == virtualPath); if (apps.Count() > 0) { site.Applications.Remove(apps.Single()); } Application app = site.Applications.Add(virtualPath, physicalPath); app.ApplicationPoolName = "Workflow AppPool"; app.EnabledProtocols = PROTOCOLS; manager.CommitChanges(); } The value assigned to virtualPath is like: "something/something/something" and for physicalPath it is "c:\inetpub\wwwroot\Workflow\something\something\something". Any ideas? Any help is greatly appreciated.
