• Strategies for managUse of types in Python

  - by dave

  I'm a long time programmer in C# but have been coding in Python for the past year. One of the big hurdles for me was the lack of type definitions for variables and parameters. Whereas I totally get the idea of duck typing, I do find it frustrating that I can't tell the type of a variable just by looking at it. This is an issue when you look at someone else's code where they've used ambiguous names for method parameters (see edit below). In a few cases, I've added asserts to ensure parameters comply with an expected type but this goes against the whole duck typing thing. On some methods, I'll document the expected type of parameters (eg: list of user objects), but even this seems to go against the idea of just using an object and let the runtime deal with exceptions. What strategies do you use to avoid typing problems in Python? Edit: Example of the parameter naming issues: If our code base we have a task object (ORM object) and a task_obj object (higher level object that embeds a task). Needless to say, many methods accept a parameter named 'task'. The method might expect a task or a task_obj or some other construct such as a dictionary of task properties - it is not clear. It is them up to be to look at how that parameter is used in order to work out what the method expects.

• Portal And Content – Introduction (1 of 7)

  - by Stefan Krantz

  The coming post over the next two months will be included in a new series. The idea is to help the reader to understand how to enable a versatile and manageable portal. Each post will go through a specific use case or lifecycle group of events that a Content Driven Portal requires the development team to consider. The current planning is to deliver following subjects, each topic will be enclosed in a separate blog post. Introduction – Introduction to the series of posts and what to expect at the end of the series Components, part 1 – UCM, Site Studio and high level introduction to content templates Components, part 2 – Page Templates and  Navigation model Components, part 3 – Applied Customization Framework for Content Presenter Taskflows Scenario 1 – Enable a Portal for runtime administration Scenario 2 – Enable a Portal for Internationalization Scenario 3 – Enable a Portal for Content Workflows Background This post series has been issued to help customers, partners and consultants to understand the concept of a WebCenter Portal project where the main focus or a majority of the portal has content interaction. Today the most portal installations Oracle WebCenter Portal is involved in have a vast majority of content based pages. Many of the Portal projects have or will run into challenges, to mitigate these challenges the portal and content lifecycle has to be well designed. The coming posts will address the main components that should be involved when creating such scenarios; it will also go into details on the process by describing three solution scenarios. The aim with the scenarios is to give the reader a more hands on understanding of the concept of building and architecting a Content Driven Portal. The selected scenarios are selected based on the most common use cases that we have identified until today.

• Cloud Computing - just get started already!

  - by BuckWoody

  OK - you've been hearing about "cloud" (I really dislike that term, but whatever) for over two years. You've equated it with just throwing some VM's in some vendor's datacenter - which is certainly part of it, but not the whole story. There's a whole world of - wait for it - *coding* out there that you should be working on. If you're a developer, this is just a set of servers with operating systems and the runtime layer (like.NET, Java, PHP, etc.) that you can deploy code to and have it run. It can expand in a horizontal way, allowing massive - and I really, honestly mean massive, not just marketing talk kind of scale. We see this every day. If you're not a developer, well, now's the time to learn. Explore a little. Try it. We'll help you. There's a free conference you can attend in November, and you can sign up for it now. It's all on-line, and the tools you need to code are free. Put down Facebook and Twitter for a minute - go sign up. Learn. Do. :) See you there. http://www.windowsazureconf.net/

• Updating an ADF Web Service Data Control When Service Structure or Location Change

  - by Shay Shmeltzer

  The web service data control in Oracle ADF gives you a simplified approach to consuming services in ADF applications, and now with ADF Mobile the usage of this service seems to be growing. A frequent question we get is what happens if the service that I'm consuming changes - how do I update my data control? Well, first we should mention that if you do a good design of your application before you actually code - then things like Web service method signature shouldn't change. The signature is the contract between the publisher and the consumer, and contracts shouldn't be broken. But in reality things do change during development stages, so here is how you can update both method signatures and service location with the Web service data control: After watching this video you might be tempted to not copy the WSDLs to your project - which lets you use the right click update on a data control. However there is a reason why the copy is on by default, it reduces network traffic when you are actually running your application since ADF doesn't need to go to the server to find out the service structure. So for runtime performance, you probably should keep the WSDL local.  I encourage you to further look into both the connections.xml file where your service location is saved, and the datacontrols.dcx file where its definition is kept to get an even deeper understanding of how ADF works underneath the declarative layers.

• Apress "Pro DLR in .NET 4' - ISBN 978-1-430203066-3 - Initial comments

  - by TATWORTH

  The dynamic language runtime (DLR) is a radical development of Dot Net. In some ways it is like the Laser was 40 years, a solution looking for a problem. At the moment the DLR supports languages such as Iron Ruby and Iron Python, together with dynamic extensions for C# and VB.NET. Where DLR will also score is the ability to write your own Dot Net language for specialist areas. So how does this book fare in introducing the DLR? It is a book that will require careful study and perhaps reading several times before fully understanding the subject. You will need to spend time trying out the sample code. So who would I recommend this book to? I recommend it to C# development teams for their library. I recommend it to individuals who not only know C# but have a good history of learning other computer languages. It is not a book that can just be "dipped into", but will require one or more reads from start to finish. This is no reflection on the skill of the author but of the newness of the material.

• Using position function for accessing particular node when using While Activity in SOA 11.1.1.5

  - by AJ

  Hi If you are using while activity in SOA Suite 11.1.1.5 and within loop you have a requirement to access repeating node of XML. You might need to use below XPATH expression for accessing the node. Here is the XML that I am using for this example <?xml version='1.0' encoding='UTF-8'?> David DemoJob 1 2012-04-15 40000 0 10 Steve TestJob 1 2012-04-15 40000 0 10 Here you can notice that Emp node is repeating i.e. EmpCollection node will contain multiple employees. Now in loop one of assign activity you need to access a particular node for e.g. For first time loop runs you want to access first node and second time second node and so on. You need to make use of postion() function like bpws:getVariableData('Receive1_Read_InputVariable','body','/ns4:EmpCollection/ns4:Emp[position()=$loopCounter]/ns4:job') Please Note: Here loopCounter is a variable that we have created of type xsd:int and prior to loop we have initialized a value of 1. Loop will run depending on the number of Emp nodes present at runtime. For that in while Activity you can use below XPATH expression ora:countNodes('Receive1_Read_InputVariable','body','/ns4:EmpCollection/ns4:Emp')=bpws:getVariableData('loopCounter') Do let me know in case of any issues or concern. Cheers AJ

• Calculating 3d rotation around random axis

  - by mitim

  This is actually a solved problem, but I want to understand why my original method didn't work (hoping someone with more knowledge can explain). (Keep in mind, I've not very experienced in 3d programming, having only played with the very basic for a little bit...nor do I have a lot of mathematical experience in this area). I wanted to animate a point rotating around another point at a random axis, say a 45 degrees along the y axis (think of an electron around a nucleus). I know how to rotate using the transform matrix along the X, Y and Z axis, but not an arbitrary (45 degree) axis. Eventually after some research I found a suggestion: Rotate the point by -45 degrees around the Z so that it is aligned. Then rotate by some increment along the Y axis, then rotate it back +45 degrees for every frame tick. While this certainly worked, I felt that it seemed to be more work then needed (too many method calls, math, etc) and would probably be pretty slow at runtime with many points to deal with. I thought maybe it was possible to combine all the rotation matrixes involve into 1 rotation matrix and use that as a single operation. Something like: [ cos(-45) -sin(-45) 0] [ sin(-45) cos(-45) 0] rotate by -45 along Z [ 0 0 1] multiply by [ cos(2) 0 -sin(2)] [ 0 1 0 ] rotate by 2 degrees (my increment) along Y [ sin(2) 0 cos(2)] then multiply that result by (in that order) [ cos(45) -sin(45) 0] [ sin(45) cos(45) 0] rotate by 45 along Z [ 0 0 1] I get 1 mess of a matrix of numbers (since I was working with unknowns and 2 angles), but I felt like it should work. It did not and I found a solution on wiki using a different matirx, but that is something else. I'm not sure if maybe I made an error in multiplying, but my question is: this is actually a viable way to solve the problem, to take all the separate transformations, combine them via multiplying, then use that or not?

• Inside the DLR – Invoking methods

  - by Simon Cooper

  So, we’ve looked at how a dynamic call is represented in a compiled assembly, and how the dynamic lookup is performed at runtime. The last piece of the puzzle is how the resolved method gets invoked, and that is the subject of this post. Invoking methods As discussed in my previous posts, doing a full lookup and bind at runtime each and every single time the callsite gets invoked would be far too slow to be usable. The results obtained from the callsite binder must to be cached, along with a series of conditions to determine whether the cached result can be reused. So, firstly, how are the conditions represented? These conditions can be anything; they are determined entirely by the semantics of the language the binder is representing. The binder has to be able to return arbitary code that is then executed to determine whether the conditions apply or not. Fortunately, .NET 4 has a neat way of representing arbitary code that can be easily combined with other code – expression trees. All the callsite binder has to return is an expression (called a ‘restriction’) that evaluates to a boolean, returning true when the restriction passes (indicating the corresponding method invocation can be used) and false when it does’t. If the bind result is also represented in an expression tree, these can be combined easily like so: if ([restriction is true]) { [invoke cached method] } Take my example from my previous post: public class ClassA { public static void TestDynamic() { CallDynamic(new ClassA(), 10); CallDynamic(new ClassA(), "foo"); } public static void CallDynamic(dynamic d, object o) { d.Method(o); } public void Method(int i) {} public void Method(string s) {} } When the Method(int) method is first bound, along with an expression representing the result of the bind lookup, the C# binder will return the restrictions under which that bind can be reused. In this case, it can be reused if the types of the parameters are the same: if (thisArg.GetType() == typeof(ClassA) && arg1.GetType() == typeof(int)) { thisClassA.Method(i); } Caching callsite results So, now, it’s up to the callsite to link these expressions returned from the binder together in such a way that it can determine which one from the many it has cached it should use. This caching logic is all located in the System.Dynamic.UpdateDelegates class. It’ll help if you’ve got this type open in a decompiler to have a look yourself. For each callsite, there are 3 layers of caching involved: The last method invoked on the callsite. All methods that have ever been invoked on the callsite. All methods that have ever been invoked on any callsite of the same type. We’ll cover each of these layers in order Level 1 cache: the last method called on the callsite When a CallSite<T> object is first instantiated, the Target delegate field (containing the delegate that is called when the callsite is invoked) is set to one of the UpdateAndExecute generic methods in UpdateDelegates, corresponding to the number of parameters to the callsite, and the existance of any return value. These methods contain most of the caching, invoke, and binding logic for the callsite. The first time this method is invoked, the UpdateAndExecute method finds there aren’t any entries in the caches to reuse, and invokes the binder to resolve a new method. Once the callsite has the result from the binder, along with any restrictions, it stitches some extra expressions in, and replaces the Target field in the callsite with a compiled expression tree similar to this (in this example I’m assuming there’s no return value): if ([restriction is true]) { [invoke cached method] return; } if (callSite._match) { _match = false; return; } else { UpdateAndExecute(callSite, arg0, arg1, ...); } Woah. What’s going on here? Well, this resulting expression tree is actually the first level of caching. The Target field in the callsite, which contains the delegate to call when the callsite is invoked, is set to the above code compiled from the expression tree into IL, and then into native code by the JIT. This code checks whether the restrictions of the last method that was invoked on the callsite (the ‘primary’ method) match, and if so, executes that method straight away. This means that, the next time the callsite is invoked, the first code that executes is the restriction check, executing as native code! This makes this restriction check on the primary cached delegate very fast. But what if the restrictions don’t match? In that case, the second part of the stitched expression tree is executed. What this section should be doing is calling back into the UpdateAndExecute method again to resolve a new method. But it’s slightly more complicated than that. To understand why, we need to understand the second and third level caches. Level 2 cache: all methods that have ever been invoked on the callsite When a binder has returned the result of a lookup, as well as updating the Target field with a compiled expression tree, stitched together as above, the callsite puts the same compiled expression tree in an internal list of delegates, called the rules list. This list acts as the level 2 cache. Why use the same delegate? Stitching together expression trees is an expensive operation. You don’t want to do it every time the callsite is invoked. Ideally, you would create one expression tree from the binder’s result, compile it, and then use the resulting delegate everywhere in the callsite. But, if the same delegate is used to invoke the callsite in the first place, and in the caches, that means each delegate needs two modes of operation. An ‘invoke’ mode, for when the delegate is set as the value of the Target field, and a ‘match’ mode, used when UpdateAndExecute is searching for a method in the callsite’s cache. Only in the invoke mode would the delegate call back into UpdateAndExecute. In match mode, it would simply return without doing anything. This mode is controlled by the _match field in CallSite<T>. The first time the callsite is invoked, _match is false, and so the Target delegate is called in invoke mode. Then, if the initial restriction check fails, the Target delegate calls back into UpdateAndExecute. This method sets _match to true, then calls all the cached delegates in the rules list in match mode to try and find one that passes its restrictions, and invokes it. However, there needs to be some way for each cached delegate to inform UpdateAndExecute whether it passed its restrictions or not. To do this, as you can see above, it simply re-uses _match, and sets it to false if it did not pass the restrictions. This allows the code within each UpdateAndExecute method to check for cache matches like so: foreach (T cachedDelegate in Rules) { callSite._match = true; cachedDelegate(); // sets _match to false if restrictions do not pass if (callSite._match) { // passed restrictions, and the cached method was invoked // set this delegate as the primary target to invoke next time callSite.Target = cachedDelegate; return; } // no luck, try the next one... } Level 3 cache: all methods that have ever been invoked on any callsite with the same signature The reason for this cache should be clear – if a method has been invoked through a callsite in one place, then it is likely to be invoked on other callsites in the codebase with the same signature. Rather than living in the callsite, the ‘global’ cache for callsite delegates lives in the CallSiteBinder class, in the Cache field. This is a dictionary, typed on the callsite delegate signature, providing a RuleCache<T> instance for each delegate signature. This is accessed in the same way as the level 2 callsite cache, by the UpdateAndExecute methods. When a method is matched in the global cache, it is copied into the callsite and Target cache before being executed. Putting it all together So, how does this all fit together? Like so (I’ve omitted some implementation & performance details): That, in essence, is how the DLR performs its dynamic calls nearly as fast as statically compiled IL code. Extensive use of expression trees, compiled to IL and then into native code. Multiple levels of caching, the first of which executes immediately when the dynamic callsite is invoked. And a clever re-use of compiled expression trees that can be used in completely different contexts without being recompiled. All in all, a very fast and very clever reflection caching mechanism.

• dynamic 2d texture creation in unity from script

  - by gman

  I'm coming from HTML5 and I'm used to having the 2D Canvas API I can use to generate textures. Is there anything similar in Unity3D? For example, let's say at runtime I want to render a circle, put 3 initials in the middle and then take the result and put that in a texture. In HTML5 I'd do this var initials = "GAT"; var textureWidth = 256; var textureHeight = 256; // create a canvas var c = document.createElement("canvas"); c.width = textureWidth; c.height = textureHeight; var ctx = c.getContext("2d"); // Set the origin to the center of the canvas ctx.translate(textureWidth / 2, textureHeight / 2); // Draw a yellow circle ctx.fillStyle = "rgb(255,255,0)"; // yellow ctx.beginPath(); var radius = (Math.min(textureWidth, textureHeight) - 2) / 2; ctx.arc(0, 0, radius, 0, Math.PI * 2, true); ctx.fill(); // Draw some black initials in the middle. ctx.fillStyle = "rgb(0,0,0)"; ctx.font = "60pt Arial"; ctx.textAlign = "center"; ctx.fillText(initials, 0, 30); // now I can make a texture from that var tex = gl.createTexture(); gl.bindTexture(gl.TEXTURE_2D, tex); gl.texImage2D(gl.TEXTURE_2D, 0, gl.RGBA, gl.RGBA, gl.UNSIGNED_BYTE, c); gl.generateMipmap(gl.TEXTURE_2D); I know I can edit individual pixels in a Unity texture but is there any higher level API for drawing to texture in unity?

• What's the best practice to do SOA exception handling?

  - by sun1991

  Here's some interesting debate going on between me and my colleague when coming to handle SOA exceptions: On one side, I support what Juval Lowy said in Programming WCF Services 3rd Edition: As stated at the beginning of this chapter, it is a common illusion that clients care about errors or have anything meaningful to do when they occur. Any attempt to bake such capabilities into the client creates an inordinate degree of coupling between the client and the object, raising serious design questions. How could the client possibly know more about the error than the service, unless it is tightly coupled to it? What if the error originated several layers below the service—should the client be coupled to those lowlevel layers? Should the client try the call again? How often and how frequently? Should the client inform the user of the error? Is there a user? By having all service exceptions be indistinguishable from one another, WCF decouples the client from the service. The less the client knows about what happened on the service side, the more decoupled the interaction will be. On the other side, here's what my colleague suggest: I believe it’s simply incorrect, as it does not align with best practices in building a service oriented architecture and it ignores the general idea that there are problems that users are able to recover from, such as not keying a value correctly. If we considered only systems exceptions, perhaps this idea holds, but systems exceptions are only part of the exception domain. User recoverable exceptions are the other part of the domain and are likely to happen on a regular basis. I believe the correct way to build a service oriented architecture is to map user recoverable situations to checked exceptions, then to marshall each checked exception back to the client as a unique exception that client application programmers are able to handle appropriately. Marshall all runtime exceptions back to the client as a system exception, along with the stack trace so that it is easy to troubleshoot the root cause. I'd like to know what you think about this? Thank you.

• Android: how do I switch between game scenes in a game? Any tutorials?

  - by Flavio

  I am trying to create a simple game using the Android SDK without using AndEngine (or any other game engine). I have plenty of experience designing games from the past, but I'm having lots of trouble trying to use the Android SDK to make my game. By far my biggest hurdle right now is switching between views. That is, for example, going from the menu to the first level, etc. I am using a traditional model I learned (I think it's called a scene stack or something?) in which you push the current scene onto a stack and the game's main loop runs the top item of the stack. This model seems non-trivial to implement in the Android SDK, mostly because Android seems to be picky about which thread instantiates which view. My issue is that I want the first level to show up when you press a button on the main menu, but when I instantiate the first level (the level class extends SurfaceView and implements SurfaceHolder.Callback) I get a runtime error complaining that the thread that runs the main menu can't instantiate this class. Something about calling Looper.prepare(). I figured at this point I was probably doing things wrong. I'm not sure how to specifically phrase my issue into a question, so maybe I should leave it as either 1) Does anybody know a good way (or the 'proper' way) to switch between scenes in an Android game? or 2) Are there any tutorials out there which show how to create a game that doesn't take place entirely in one scene? (I have googled for a while to no avail... maybe someone else knows of one?) Thanks!

• About shared (static) Members and its behavior

  - by Allende

  I just realized that I can access shared members from instances of classes (probably this is not correct, but compile and run), and also learn/discover that, I can modify shared members, then create a new instance and access the new value of the shared member. My question is, what happens to the shared members, when it comes back to the "default" value (class declaration), how dangerous is it do this ? is it totally bad ? is it valid in some cases ?. If you want to test my point here is the code (console project vb.net) that I used to test shared members, as you can see/compile/run, the shared member "x" of the class "Hello" has default value string "Default", but at runtime it changes it, and after creating a new object of that class, this object has the new value of the shared member. Module Module1 Public Class hello Public Shared x As String = "Default" Public Sub New() End Sub End Class Sub Main() Console.WriteLine("hello.x=" & hello.x) Dim obj As New hello() Console.WriteLine("obj.x=" & obj.x) obj.x = "Default shared memeber, modified in object" Console.WriteLine("obj.x=" & obj.x) hello.x = "Defaul shared member, modified in class" Console.WriteLine("hello.x=" & hello.x) Dim obj2 As New hello() Console.WriteLine("obj2.x=" & obj2.x) Console.ReadLine() End Sub End Module UPDATE: First at all, thanks to everyone, each answer give feedback, I suppose, by respect I should choose one as "the answer", I don't want to be offensive to anyone, so please don't take it so bad if I didn't choose you answer.

• Generated 3d tree meshes

  - by Jari Komppa

  I did not find a question on these lines yet, correct me if I'm wrong. Trees (and fauna in general) are common in games. Due to their nature, they are a good candidate for procedural generation. There's SpeedTree, of course, if you can afford it; as far as I can tell, it doesn't provide the possibility of generating your tree meshes at runtime. Then there's SnappyTree, an online webgl based tree generator based on the proctree.js which is some ~500 lines of javascript. One could use either of above (or some other tree generator I haven't stumbled upon) to create a few dozen tree meshes beforehand - or model them from scratch in a 3d modeller - and then randomly mirror/scale them for a few more variants.. But I'd rather have a free, linkable tree mesh generator. Possible solutions: Port proctree.js to c++ and deal with the open source license (doesn't seem to be gpl, so could be doable; the author may also be willing to co-operate to make the license even more free). Roll my own based on L-systems. Don't bother, just use offline generated trees. Use some other method I haven't found yet.

• ImageResizer - AzureReader2 with Azure SDK 2.2

  - by Chris Skardon

  Originally posted on: http://geekswithblogs.net/cskardon/archive/2013/10/29/imageresizer---azurereader2-with-azure-sdk-2.2.aspxSo Azure SDK 2.2 came out recently, which means I can open my azure projects in VS 2013 (yay), so I decided to do an upgrade of my MVC4 project to MVC5, I followed this link on how to do the upgrade, and generally things went ok. I fire up my app, and run into a ‘binding’ issue, that AzureReader2 was trying to use Microsoft.WindowsAzure.Storage, Version=2.1.0.0 but alas, it couldn’t find it. I am not the only one (see stackoverflow), and one solution is to run ‘Add-BindingRedirect’ from the Package Manager Console, but that didn’t solve the problem for me, as it didn’t pick up on the Azure stuff, so I resorted to adding the redirect manually. So, in short, to get AzureReader2 to work with Azure SDK 2.2, you need to add the following to your web.config: <runtime> <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1"> <!-- Other bindings here! --> <dependentAssembly> <assemblyIdentity name="Microsoft.WindowsAzure.Storage" publicKeyToken="31bf3856ad364e35" culture="neutral"/> <bindingRedirect oldVersion="0.0.0.0-2.1.0.3" newVersion="2.1.0.3"/> </dependentAssembly> </assemblyBinding>

• What stops HTML5 and JS apps to perform as good as native apps?

  - by Amogh Talpallikar

  From what I understand, HTML is a mark-up language, so is the content of XAML, XIB and whatever Android uses and other native UI development frameworks. JavaScript is a programming language used along with it to handle client side scripting which will include things like event handling, client side validations and anything else C#,Java,Objective-C or C++ do in various such frameworks. There are MVC/MVVM patterns available in form frameworks like Sencha's, Angular etc. We have localStorage in form of both sqlite and key-value store as other frameworks have and you have API specification for almost everything that it missing. Whenever a native UI frameworks has to render UI , it has to parse a similar the markup and render the UI. Question break-down What stops from doing the same in HTML and JS itself ? Instead of having a web-control or browser as a layer in between why can't HTML(along with CSS) and JS be made to perform the same way ? Even if there is a layer,so does .net runtime and JVM are in other cases where C++,C are not being used. So Lets take the case of Android, like Dalvik, why Can't Chromium be another option(along with dalvik and NDK) where HTML does what android markup does and JavaScript is used to do what Java does ? So the Question is, Even if current implementations aren't as good, but theoretically is it possible to get HTML5 based applications to work as other native apps specially on mobile ?

• Why do the GNOME symbolic icons appear darker in a running application?

  - by David Planella

  I'm creating an application that uses symbolic icons from the default theme. However, there are a few icons that I need that cannot be represented by those from the default theme, so I'm creating my own ones. What I did was to simply go to /usr/share/icons/gnome/scalable/actions/, copied a few locally into my app's source tree that could serve as a basis, and started editing them. So far so good. But I've noticed the following: all symbolic icons are of a light grey color when looking at the original .svg file, but when they are put onto a widget, they become darker. Here's an example, using the /usr/share/icons/gnome/scalable/actions/view-refresh-symbolic.svg icon from the default theme: Here's what it looks like when opening the original with Inkscape: And here's what it looks like on a toolbar on a running application: Notice the icon being much darker at runtime. That happens both with the Ambiance and Radiance themes. I wouldn't mind much, but I noticed it affects my custom icon, whereby parts of it become darker (the inner fill), whereas parts of it remain the same color as the original (the stroke). So what causes the default symbolic icons to darken and how should implement that for my custom icons?

• Basic AppFabric Service Bus Programming Lifecycle

  - by kaleidoscope

  The tasks required to create an application that access the AppFabric Service Bus are as follows: Create a service namespace. This service namespace contains the resources used by the AppFabric Service Bus to support the application. Define the AppFabric Service Bus contract. A contract specifies the signature of the service, the data it exchanges, and other required inputs, behavior specifications, and object invariants. Implement the contract. To implement a service contract, create a class that implements the interface and specify custom runtime behaviors. Configure the service by specifying endpoint and other behavior information. Build and run the service. Build and run the client application. As with any iterative, service-oriented software development, it may not always be appropriate to follow the preceding steps sequentially, or even start from step 1. For example, if you want to build a client for a pre-existing service, you start at step 5. Or, if you are building a host service that others will use, you can skip step 6.

• Importing tab delimited file into array in Visual Basic 2013 [migrated]

  - by JaceG

  I am needing to import a tab delimited text file that has 11 columns and an unknown number of rows (always minimum 3 rows). I would like to import this text file as an array and be able to call data from it as needed, throughout my project. And then, to make things more difficult, I need to replace items in the array, and even add more rows to it as the project goes on (all at runtime). Hopefully someone can suggest code corrections or useful methods. I'm hoping to use something like the array style sMyStrings(3,2), which I believe would be the easiest way to control my data. Any help is gladly appreciated, and worthy of a slab of beer. Here's the coding I have so far: Imports System.IO Imports Microsoft.VisualBasic.FileIO Public Class Main Dim strReadLine As String Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Dim sReader As IO.StreamReader = Nothing Dim sRawString As String = Nothing Dim sMyStrings() As String = Nothing Dim intCount As Integer = -1 Dim intFullLoop As Integer = 0 If IO.File.Exists("C:\MyProject\Hardware.txt") Then ' Make sure the file exists sReader = New IO.StreamReader("C:\MyProject\Hardware.txt") Else MsgBox("File doesn't exist.", MsgBoxStyle.Critical, "Error") End End If Do While sReader.Peek >= 0 ' Make sure you can read beyond the current position sRawString = sReader.ReadLine() ' Read the current line sMyStrings = sRawString.Split(New Char() {Chr(9)}) ' Separate values and store in a string array For Each s As String In sMyStrings ' Loop through the string array intCount = intCount + 1 ' Increment If TextBox1.Text <> "" Then TextBox1.Text = TextBox1.Text & vbCrLf ' Add line feed TextBox1.Text = TextBox1.Text & s ' Add line to debug textbox If intFullLoop > 14 And intCount > -1 And CBool((intCount - 0) / 11 Mod 0) Then cmbSelectHinge.Items.Add(sMyStrings(intCount)) End If Next intCount = -1 intFullLoop = intFullLoop + 1 Loop End Sub
