• OpenGL: Want to keep gun on top of car and be able to control angle. Having difficulties.

  - by Blair

  So I am making a simple game. I want to put a gun on top of a car so basically like a long rod in the middle of a black is how I am modelling it right now. I want to be able to control the angle of the gun. Basically it can go forward all the way so that it is parallel to the ground facing the direction the car is moving or it can point behind the car and any of the angles in between these positions. I have something like the following right now but its not really working. Is there an better way to do this that I am not seeing? #This will place the car glPushMatrix() glTranslatef(self.position.x,1.5,self.position.z) glRotated(self.rotation, 0.0, 1.0, 0.0) glScaled(0.5, 0.5, 0.5) glCallList(self.model.gl_list) glPopMatrix() #This will place the gun on top glPushMatrix() glTranslatef(self.position.x,2.5,self.position.z) glRotated(self.tube_angle, self.direction.z, 0.0, self.direction.x) print self.direction.z glRotated(45, self.position.z, 0.0, self.position.x) glScaled(1.0, 0.5, 1.0) glCallList(self.tube.gl_list) glPopMatrix() This almost works. It moves the gun up and down. But when the car moves around the angle of the gun changes. Not what I want.

• Startup/Shutdown time in Xubuntu is increasing!

  - by Ankit

  I am a novice Xubuntu user on a dual-boot machine. The other OS I have is Windows 7. When I first began using Xubuntu, I had really fast startup and shutdown (much much faster than Windows 7 :) ). However, as I started using it more and more for my work, these times started rising. I do not have any problems with execution speed of running applications. My main concern is the shutdown time. Now it has gone above Windows shutdown time [startup time has only partially increase compared to shutdown]. I checked some similar questions like this. However, they seem to not answer my concern as I feel that the concerned users there experience a long wait before the screen goes blue. In my case, the screen goes blue (desktop session ends a blue screen with a moving slider appears) pretty fast. However, it remains blue for a long time. Another answer that I saw on google was to use dmesg and then stopping some services that I do not want. However, me being a novice could not completely understand what it meant

• BizTalk: Dynamic SMTP Port: Unknown Error Description

  - by Leonid Ganeline

  Today I investigated one strange error working with Dynamic SMTP Port.   Event Type: Error Event Source: BizTalk Server 2006 Event Category: BizTalk Server 2006 Event ID: 5754 Date: ******** Time: ********AM User: N/A Computer: ******** Description: A message sent to adapter "SMTP" on send port "*********" with URI "mailto:********.com" is suspended. Error details: Unknown Error Description  MessageId:  {********} InstanceID: {********}   My code was pretty simple and the source of the error was hidden somewhere inside it.   msg_MyMessage(SMTP.CC) = var_CC; msg_MyMessage(SMTP.From) = var_From; msg_MyMessage(SMTP.Subject) = var_Subject; msg_MyMessage(SMTP.EmailBodyText) = var_Message;    // #1    msg_MyMessage(SMTP.SMTPHost) = " localhost "; msg_MyMessage(SMTP.SMTPAuthenticate) = 0; When I added line #2, this frustrating error disappeared.    msg_MyMessage(SMTP.EmailBodyTextCharset) = "UTF-8"; // #2 Conclusion: If we use the SMTP.EmailBodyText property, we must set up the SMTP.EmailBodyTextCharset property. To me it looks like a bug in BizTalk. [Maybe it is "by design", but in this case give us a useful error text!!!] And don't ask me how much time I've spent with this investigation.

• Nvidia optimus and Steam (on 12.04)

  - by Seiryuu

  I've obtained a copy of the .deb for the Steam beta, but it was pretty disappointing to see that it simply doesn't run. Hardware - Dell XPS L502, with Nvidia Optimus I have bumblebee installed. Trying to run Steam with the Intel HD 3000 completely fails to start it. Message received Installing breakpad exception handler for appid(steam)/version(1352224866_client) followed by a crash with no other information provided. Trying to optirun steam runs the client, but as soon as it gets to the home screen, it says that the Nvidia drivers I am using are out of date (and Steam requires newer drivers to run). It's probably worth to note that it throws the same Installing breakpad... error when run with optirun, but it doesn't crash the client immediately. Any way to fix this? Also, is there a way of manually updating the drivers in bumblebee without breaking anything? Alternatively, is there a reliable way of completely disabling the Intel GPU (in order to use the Nvidia GPU exclusively)? Note: I am using Xmonad with gnome-fallback, if that makes a difference. However, when I tried everything mentioned with Unity (2d), everything was the same, so I guess it has nothing to do with the window manager in use.

• Can One Get a Solid Programming Foundation Without Going To College/University?

  - by Daniel

  First, I have already searched the site and read all the previous "self-taught vs. college" topics. The majority of the answers defended that going to college was the best choice, for two main reasons: Going to college gives you the paper, which is essential to landing jobs, especially in tough economic times. Going to college gives you a solid programming base, teaching you the principles that will be essential regardless of the language/path you take after. Here comes my question: I am not worried about reason 1 at all, because I already have my own company (I build websites/ do affiliate marketing) and a stable financial situation, so I am pretty sure I won't need to look around for a job. I am worried about reason 2 though. That is, I want to make sure I'll have as solid a programming foundation as anyone else out there, and I am wondering if that is possible with self-learning. Suppose I take my time to study the very basics, like discrete maths, algorithm design, programming logic, computer architecture, Assembly, C programming, databases and data structures - mostly using books,online resources and lots of coding. Say I spend 1-2 years covering those basics. Do you think my foundation would be solid, or still lack in comparison to someone who went to college?

• Enigmail - how to encrypt only part of the message?

  - by Lukasz Zaroda

  When I confirmed my OpenPGP key on launchpad I got a mail from them, that was only partially encrypted with my key (only few paragraphs inside the message). Is it possible to encrypt only chosen part of the message with Enigmail? Or what would be the easiest way to accomplish it? Added #1: I found a pretty convenient way for producing ASCII armoured encrypted messages by using Nautilus interface (useful for ones that for some reason doesn't like to work with terminal). You need to install Nautilus-Actions Configuration Tool, and add there a script with a name eg. "Encrypt in ASCII" and parameters: path: gpg parameters: --batch -sear %x %f The trick is that now you can create file, with extension that would be name of your recipient, you can then fill it with your message, right click it in Nautilus, choose "Encrypt in ASCII", and you will have encrypted ascii file which content you can (probably) just copy to your message. But if anybody knows more convenient solution please share it. Added #1B: In the above case if you care more about security of your messages, It's worth to turning off invisible backup files that gedit creates every time, you create new document, or just remember to delete them.

• SQL Saturday Atlanta: Intro To Performance Tuning

  - by Mike Femenella

  I'm looking forward to speaking in Atlanta on the 24th, will be fun to get back down that way to visit with some friends and present two topics that I really enjoy. First, an introduction to performance tuning. Performance tuning is a very wide and deep topic and we're staying close to the surface. I direct this class for newbie sql users who have less than 2 years of experience. It's all the things I wish someone would have told me in my first 2 years about what to look for when the database was slow...or allegedly slow I should say. We'll cover using profiler to find slow performing queries and how to save the data off to a table as well as a tour of other features. The difference between clustered, non clustered and covering indexes. How to look at and understand an execution plan (at a high level) and finally the difference between a temp table and a table variable and what the implications are of using either one in your code. That pretty much takes up a full hour. Second presentation, Loading Data in Real Time. It's really a presentation about partitioning but with a twist that we used at work recently to solve a need to load some data quickly and put it into production with minimal downtime. We'll cover partition functions, schemes,$partition, merge, sys.partitions and show some examples of building a set of partitioned tables and using the switch statement to move it from one table to another. Finally we'll cover the differences in partitioning between 2005 and 2008. Hope to see you there! And if you read my blog please introduce yourself!

• Help to organize game cycle in Java

  - by ASIO22

  I'm pretty new here (as though to a game development). So here's my question. I'm trying to organize a really simple game cycle in my public static main() as follows: Scanner sc = new Scanner(System.in); //Running the game cycle boolean flag=true; while (flag) { int action; System.out.println("Type your action please:"); System.out.println("0: Exit app"); try { action = sc.nextInt(); switch (action) { case 0: flag=false; break; case 1: break; } } catch (InputMismatchException ex) { System.out.println(ex.getClass() + "\n" + "Please type a correct input\n"); //action = sc.nextInt(); continue; } What's wrong with this cycle: I want to catch an exception when user types text instead of number, show a message, warning user, and the continue game cycle, read user input etc. But instead of that, when users types wrong data, it goes into a eternal cycle without even prompting user. What I did wrong?

• Is Oracle certified to run on VMWare?

  - by Mike Dietrich

  This question in similar occurences gets asked during every Upgrade Workshop at least once. People would like to know if they can run an Oracle Database or Oracle Real Application Clusters or Oracle Grid Control or Oracle Fusion Middleware or ... in an VM environment with VMWare's virtualisation products. And the answer is: Yes, you can!! But ... there's a fine print you should take care on before setting up virtual environments with a different solution than XEN based Oracle VM. Please read Note:942852.1 - VMWare Certification for Oracle Products and Note:249212.1 - Support Position for Oracle Products Running on VMWare Virtualized Environments for further details: Support Status for VMware Virtualized Environments Oracle has not certified any of its products on VMware virtualized environments. Oracle Support will assist customers running Oracle products on VMware in the following manner: Oracle will only provide support for issues that either are known to occur on the native OS, or can be demonstrated not to be as a result of running on VMware. If a problem is a known Oracle issue, Oracle support will recommend the appropriate solution on the native OS. If that solution does not work in the VMware virtualized environment, the customer will be referred to VMware for support. When the customer can demonstrate that the Oracle solution does not work when running on the native OS, Oracle will resume support, including logging a bug with Oracle Development for investigation if required. If the problem is determined not to be a known Oracle issue, we will refer the customer to VMware for support. When the customer can demonstrate that the issue occurs when running on the native OS, Oracle will resume support, including logging a bug with Oracle Development for investigation if required. NOTE: Oracle has not certified any of its products on VMware. For Oracle RAC, Oracle will only accept Service Requests as described in this note on Oracle RAC 11.2.0.2 and later releases.

• Alternatives for the Snippet Compiler

  - by Marko Apfel

  It seems that the Snippet Compiler is not maintained anymore. So I need an alternative – also for getting syntax highlighting for code in publications. Preferable with the possibility to conserve this highlighting by copying selections to clipboard. Snippet Compiler does not allows this for selections – only by exporting the whole file content to clipboard with HTML- or RTF-formatting (File > Export > HTML to clipboard respectively RTF to clipboard). Today I switched to LINQPad. This application offers constructing LINQ-statements as well as compiling arbitrary code snippets. But there are some other alternatives too: CS-Script - The C# Script Engine CS-Script is a CLR (Common Language Runtime) based scripting system which uses ECMA-compliant C# as a programming language. CS-Script currently targets Microsoft implementation of CLR (.NET 2.0/3.0/3.5. sharpsnippetcompiler C# Snippet Compiler is a tiny IDE to create, debug and run your C# programs CsharpRepl C# interactive shell that is part of Mono's C# compiler. An interactive shell is usually referred to as a read eval print loop or repl. The C# interactive shell is built on top of the Mono.CSharp library, a library that provides a C# compiler service that can be used to evaluate expressions and statements on the flight. What I miss is an alternative with syntax highlighting like in my Visual Studio: Instead of:

• If You Include the Groovy Editor...

  - by Geertjan

  ...in a NetBeans RCP application, what additional JARs will you need to include for the Groovy Editor to work? Leaving aside the debate on the current state & quality of the NetBeans Groovy Editor, so, assuming you need the Groovy support that the NetBeans Groovy Editor provides, you would check the Groovy Editor checkbox in the Project Properties dialog of your application: As you can see, however, the Groovy Editor depends on other modules, some of which, in turn, depend on yet other modules, and so on. So, I clicked the "Resolve" button above and then created a ZIP distribution, to see which additional JARs had been included. Until that point, I had only been using the "platform" cluster, which means that absolutely everything found in the ZIP's "ide" cluster and "java" cluster have only been included so that the Groovy Editor could be included, i.e., all thanks to clicking the "Resolve" button above. Let's first look at what that means for the "java" cluster: That's not so bad and kind of a side effect of Groovy being Java, i.e., a lot of Java functionality is needed. Now let's look at the "ide" cluster: So, in answer to the original question, if all you want in your NetBeans Platform application, in terms of editor functionality, is the Groovy Editor, then you have a pretty high price to pay. At the very least, I would have assumed that the project support JARs and the debugger support JARs would not be so tightly coupled with the Groovy Editor. That would be a cool thing to separate out from the editor support.

• How can I use iteration to lead targets?

  - by e100

  In my 2D game, I have stationary AI turrets firing constant speed bullets at moving targets. So far I have used a quadratic solver technique to calculate where the turret should aim in advance of the target, which works well (see Algorithm to shoot at a target in a 3d game, Predicting enemy position in order to have an object lead its target). But it occurs to me that an iterative technique might be more realistic (e.g. it should fire even when there is no exact solution), efficient and tunable - for example one could change the number of iterations to improve accuracy. I thought I could calculate the current range and thus an initial (inaccurate) bullet flight time to target, then work out where the target would actually be by that time, then recalculate a more accurate range, then recalculate flight time, etc etc. I think I am missing something obvious to do with the time term, but my aimpoint calculation does not currently converge after the significant initial correction in the first iteration: import math def aimpoint(iters, target_x, target_y, target_vel_x, target_vel_y, bullet_speed): aimpoint_x = target_x aimpoint_y = target_y range = math.sqrt(aimpoint_x**2 + aimpoint_y**2) time_to_target = range / bullet_speed time_delta = time_to_target n = 0 while n <= iters: print "iteration:", n, "target:", "(", aimpoint_x, aimpoint_y, ")", "time_delta:", time_delta aimpoint_x += target_vel_x * time_delta aimpoint_y += target_vel_y * time_delta range = math.sqrt(aimpoint_x**2 + aimpoint_y**2) new_time_to_target = range / bullet_speed time_delta = new_time_to_target - time_to_target n += 1 aimpoint(iters=5, target_x=0, target_y=100, target_vel_x=1, target_vel_y=0, bullet_speed=100)

• Adventures in MVVM &ndash; My ViewModel Base &ndash; Silverlight Support!

  - by Brian Genisio's House Of Bilz

  More Adventures in MVVM In my last post, I outlined the powerful features that are available in the ViewModelSupport.  It takes advantage of the dynamic features of C# 4.0 (as well as some 3.0 goodies) to help eliminate the plumbing that often comes with writing ViewModels.  If you are interested in learning about the capabilities, please take a look at that post and look at the code on CodePlex.  When I wrote about the ViewModel base class, I complained that the features did not work in Silverlight because as of 4.0, it does not support binding to dynamic properties.  Although I still think this is a bummer, I am happy to say that I have come up with a workaround.  In the Silverlight version of my base class, I include a PropertyCollectionConverter that lets you bind to dynamic properties in the ViewModelBase, especially the convention-based commands that the base class supports. To take advantage of any properties that are not statically defined, you can bind to the Properties property of the ViewModel and pass in a converter parameter for the name of the property you want to bind. For example, a ViewModel that looks like this: public class ExampleViewModel : ViewModelBase { public void Execute_MyCommand() { Set("Text", "Foo"); } } Can bind to the dynamic property and the convention-based command with the following XAML. <TextBlock Text="{Binding Properties, Converter={StaticResource PropertiesConverter}, ConverterParameter=Text}" Margin="5" /> <Button Content="Execute MyCommand" Command="{Binding Properties, Converter={StaticResource PropertiesConverter}, ConverterParameter=MyCommand}" Margin="5" /> Of course, it is not as pretty as binding to Text and MyCommand like you can in WPF.  But, it is better than having a failed feature.  This allows you to share your ViewModels between WPF and Silverlight very easily.  <BeatDeadHorse>Hopefully, in Silverlight 5.0, we will see binding to dynamic properties more directly????</BeatDeadHorse>

• How do I structure code and builds for continuous delivery of multiple applications in a small team?

  - by kingdango

  Background: 3-5 developers supporting (and building new) internal applications for a non-software company. We use TFS although I don't think that matters much for my question. I want to be able to develop a deployment pipeline and adopt continuous integration / deployment techniques. Here's what our source tree looks like right now. We use a single TFS Team Project. $/MAIN/src/ $/MAIN/src/ApplicationA/VSSOlution.sln $/MAIN/src/ApplicationA/ApplicationAProject1.csproj $/MAIN/src/ApplicationA/ApplicationAProject2.csproj $/MAIN/src/ApplicationB/... $/MAIN/src/ApplicationC $/MAIN/src/SharedInfrastructureA $/MAIN/src/SharedInfrastructureB My Goal (a pretty typical promotion pipeline) When a code change is made to a given application I want to be able to build that application and auto-deploy that change to a DEV server. I may also need to build dependencies on Shared Infrastructure Components. I often also have some database scripts or changes as well If developer testing passes I want to have an manually triggered but automated deploy of that build on a STAGING server where end-users will review new functionality. Once it's approved by end users I want to a manually triggered auto-deploy to production Question: How can I best adopt continuous deployment techniques in a multi-application environment? A lot of the advice I see is more single-application-specific, how is that best applied to multiple applications? For step 1, do I simply setup a separate Team Build for each application? What's the best approach to accomplishing steps 2 and 3 of promoting latest build to new environments? I've seen this work well with web apps but what about database changes

• Best algorithm for recursive adjacent tiles?

  - by OhMrBigshot

  In my game I have a set of tiles placed in a 2D array marked by their Xs and Zs ([1,1],[1,2], etc). Now, I want a sort of "Paint Bucket" mechanism: Selecting a tile will destroy all adjacent tiles until a condition stops it, let's say, if it hits an object with hasFlag. Here's what I have so far, I'm sure it's pretty bad, it also freezes everything sometimes: void destroyAdjacentTiles(int x, int z) { int GridSize = Cubes.GetLength(0); int minX = x == 0 ? x : x-1; int maxX = x == GridSize - 1 ? x : x+1; int minZ = z == 0 ? z : z-1; int maxZ = z == GridSize - 1 ? z : z+1; Debug.Log(string.Format("Cube: {0}, {1}; X {2}-{3}; Z {4}-{5}", x, z, minX, maxX, minZ, maxZ)); for (int curX = minX; curX <= maxX; curX++) { for (int curZ = minZ; curZ <= maxZ; curZ++) { if (Cubes[curX, curZ] != Cubes[x, z]) { Debug.Log(string.Format(" Checking: {0}, {1}", curX, curZ)); if (Cubes[curX,curZ] && Cubes[curX,curZ].GetComponent<CubeBehavior>().hasFlag) { Destroy(Cubes[curX,curZ]); destroyAdjacentTiles(curX, curZ); } } } } }

• Distinction between API and frontend-backend

  - by Jason

  I'm trying to write a "standard" business web site. By "standard", I mean this site runs the usual HTML5, CSS and Javascript for the front-end, a back-end (to process stuff), and runs MySQL for the database. It's a basic CRUD site: the front-end just makes pretty whatever the database has in store; the backend writes to the database whatever the user enters and does some processing. Just like most sites out there. In creating my Github repositories to begin coding, I've realized I don't understand the distinction between the front-end back-end, and the API. Another way of phrasing my question is: where does the API come into this picture? I'm going to list some more details and then questions I have - hopefully this gives you guys a better idea of what my actual question is, because I'm so confused that I don't know the specific question to ask. Some more details: I'd like to try the Model-View-Controller pattern. I don't know if this changes the question/answer. The API will be RESTful I'd like my back-end to use my own API instead of allowing the back-end to cheat and call special queries. I think this style is more consistent. My questions: Does the front-end call the back-end which calls the API? Or does the front-end just call the API instead of calling the back-end? Does the back-end just execute an API and the API returns control to the back-end (where the back-end acts as the ultimate controller, delegating tasks)? Long and detailed answers explaining the role of the API alongside the front-end back-end are encouraged. If the answer depends on the model of programming (models other than the Model-View-Controller pattern), please describe these other ways of thinking of the API. Thanks. I'm very confused.

• Developing a mobile application, how to show help if it contains too much data?

  - by MobileDev123

  I am developing a mobile application which has many functionality, and I am pretty sure that the design will confuse the user about how to use some functionality so we decided to include some help as we can see them regularly in desktop applications, but later we found that the help text is too long. We don't think that one screen is enough to describe what a user can do. Moreover the project itself is subjected to evolve based on beta stage and user reports. After a lot of thinking and meetings we have decided three options to show the users what they can do. Create the website or blog, so we can let the users know what they can do with this application, the advantage is that it can provide us a good source of marketing, but for that they have to access the site while most part of the application can be used while being offline in earlier versions. Create a section in the application called demos to show the same thing locally, but we are afraid that it will increase the size, that we think can be avoided (and we are planning to avoid if there is any option) Show popups, but we discarded this thinking that pop ups annoys user no matter what the platform is. I want to know from community that which option will you choose, we are also open to accept other ideas if you have.

• What is a generic term for name/identifier? (as opposed to label)

  - by d3vid

  I need to refer to a number of things that have both an identifier value (used in code and configuration), and a human-readable label. These things include: database columns dropdown items subapplications objects stored in a dictionary I want two unambiguous terms. One to refer to the identifier/value/key. One to refer to the label. As you can see, I'm pretty settled on the latter :) For the former, identifier seems best (not everything is strictly a key, and value and name could refer to the label; although, identifier usually refers only to a variable name), but I would prefer to follow an established practice if there is one. Is there an established term for this? (Please provide a source.) If not, are there any examples of a choice from a significant source (Java APIs, MSDN, a big FLOSS project)? (I wasn't sure if this should be posted here or to English Language & Usage. I thought this was the more appropriate expert audience. Happy to migrate if not.)

• what receives an ajax call?

  - by jbcolmenares

  I'm making a site which should (a) take information from the user in the form of files and forms, (b) take that data to the server to be run on a C application, and (c) take the result back and show it to the user. I was told to look for AJAX for the communication with the server. BTW, I'm using rails. I'm trying to understand how AJAX works. From what I understand so far, with rails is pretty easy to make the call. What I can't figure out is, what waits for that call? what process the call? If I understand correctly, with rails I could make a function in ruby and make it so it's called through AJAX, which means -or so I understand- that it gets executed on the server. If I were using PHP, would I need to make an http server to wait for the AJAX calls? I just don't find information about what waits for the call, and that information is processed. Any links, comments or books are welcome!

• USB Device first mounted as root, then by user

  When I connect my Kindle, it shows up as an usb0 media, which I can read but not write (owner = root). However, if I do sudo umount /media/usb0, usb0 gets unmounted and a Kindle media gets mounted properly (is writable etc.). What can cause such strange behavior?

• Coarse Collision Detection in highly dynamic environment

  - by Millianz

  I'm currently working a 3D space game with A LOT of dynamic objects that are all moving (there is pretty much no static environment). I have the collision detection and resolution working just fine, but I am now trying to optimize the collision detection (which is currently O(N^2) -- linear search). I thought about multiple options, a bounding volume hierarchy, a Binary Spatial Partitioning tree, an Octree or a Grid. I however need some help with deciding what's best for my situation. A grid seems unfeasible simply due to the space requirements and cache coherence problems. Since everything is so dynamic however, it seems to be that trees aren't ideal either, since they would have to be completely rebuilt every frame. I must admit I never implemented a physics engine that required spatial partitioning, do I indeed need to rebuild the tree every frame (assuming that everything is constantly moving) or can I update the trees after integrating? Advice is much appreciated - to give some more background: You're flying a space ship in an asteroid field, and there are lots and lots of asteroids and some enemy ships, all of which shoot bullets. EDIT: I came across the "Sweep an Prune" algorithm, which seems like the right thing for my purposes. It appears like the right mixture of fast building of the data structures involved and detailed enough partitioning. This is the best resource I can find: http://www.codercorner.com/SAP.pdf If anyone has any suggestions whether or not I'm going in the right direction, please let me know.

• Hosting WCF over internet

  - by user1876804

  I am pretty new to exposing the WCF services hosted on IIS over internet. I will be deploying a WCF service over IIS(6 or 7) and would like to expose this service over the internet. This will be hosted in a corporate network having firewall, I want this service to be accessible over the internet(should be able to pass through the firewall) I did some research on this and some of the pointers I got: 1. I could use wsHTTPBinding or nettcpbinding (the client is intended to be .net client). Which of the bindings is preferable. 2. To overcome the corporate I came across DMZ server, what is the purpose of this and do I really need to use this). 3. I will be passing some files between the client and server, and the client needs to know the progress of the processing on server and the end result. I know this is a very broad question to ask, but could anyone give me pointers where I could start on this and what approach to take for this problem.

The new functionality includes: APIs for Import of Contract Templates, Contract Expert rules, Questions and Constants: The three APIs are as follows: API for Templates, API for Rules, and API for Questions and Constants. These can be used to both create entities and update existing templates and rules. The APIs will display error and warning messages which can be processed and analyzed by the customer. Ability to Apply Multiple Templates to a Sourcing, Procurement or Sales Document: The buyer can select and add multiple templates to a quote,sales agreement document, sourcing or purchasing odcument.  All the clauses and deliverables from the new templates are synchronized with the document. The Contract Expert rules are from the original template. The buyer can also view the list of templates that are added to any sales or procurement document. Ability to Define Multi-Row Variables: You can create user defined manual variables that are tables containing one row per line or multiple rows. Contract Preview will print the variable values according to the layout defined for the variable. These variables are not available for Contract Expert Rules and Supplier. Enhancement to Suggested Sections for Clauses by Contract Expert: You can associate multiple default sections with a clause. A clause is associated with multiple values of any system variable and for each such value a section name is associated in Contracts Terms Library. When Contract Expert is run in the contract authoring flow, the clause is automatically placed in the associated section name. Plus many more new features.

• Hotspotting - tying Visualization into Other applications

  - by warren.baird

  AutoVue 20 included our first step towards providing a rich hotspotting capability that will allow visualization capabilities to be very tightly integrated into a wide range of applications. The idea is to have a close link between the visual representation of an object or place, and the business objects associated with that object or place. We've been working with our partner Enigma to enable this capability in their parts catalogue - the screenshot above shows what it looks like - the image on the right is a trimmed down version of AutoVue displaying a drawing of the various parts in an interactive way - when you click on item '6' in the AutoVue drawing, the appropriate item is highlighted in the parts catalogue - making it easy to select the parts you need, and to ensure that the correct parts are selected. The integration works in both directions - when you select a part in the part catalogue, the appropriate part is highlighted in the drawing as well. To get slightly technical for a moment, this is a simple javascript integration - the external application provides a javascript callback that AutoVue calls whenever an item is clicked on, and AutoVue provides a javascript function to call when an item is selected in the external application. There are also direct java APIs available. This makes it easy to tie AutoVue into many types of applications - you can imagine in an asset lifecycle management application being able to click on the appropriate asset in a drawing to create a work-order, instead of finding the right asset ID to enter. Or being able to click on a part or sub-assembly to trigger a change order in a product lifecycle management application. We're pretty excited about the possibilities that this capability opens up, and plan on expanding on it a lot in the future. Would this be useful in your enterprise applications? What kinds of integrations like this would be useful for you? Let us know in the comments below!

• How I use RegExp in my Java program? [migrated]

  - by MIH1406

  I have the following string examples: 00001 1 12 123 00002 3 7 321 00003 99 23 332 00004 192 50 912 In a separate text file. Numbers are separated by tabs not spaces. I tried to read the file and print each line if it matches a given RegExp, but I could not find the suitable RegExp for these lines. private static void readFile() { String fileName = "processes.lst"; FileReader file = null; String result = ""; try { file = new FileReader(fileName); BufferedReader reader = new BufferedReader(file); String line = null; String regEx = "[0-9]\t[0-9]\t[0-9]\t[0-9]"; while((line = reader.readLine()) != null) { if(line.matches(regEx)) { result += "\n" + line; } } } catch(Exception e) { System.out.println(e.getMessage()); } finally { if(file != null) try { file.close(); } catch(Exception e) { System.out.println(e.getMessage()); } } System.out.println(result); } I ended up without any string being printed!!
