• convert a class to byte array + C#

  - by Newbie

  How can I convert a Class to byte array in C#. This is a managed one so the following code is failing int objsize = System.Runtime.InteropServices.Marshal.SizeOf(objTimeSeries3D); byte[] arr = new byte[objsize]; IntPtr buff = System.Runtime.InteropServices.Marshal.AllocHGlobal(objsize); System.Runtime.InteropServices.Marshal.StructureToPtr(objTimeSeries3D, buff, true); System.Runtime.InteropServices.Marshal.Copy(buff, arr, 0, objsize); System.Runtime.InteropServices.Marshal.FreeHGlobal(buff); Thanks

• I need to modify a program to use arrays and a method call. Should I modify the running file, the data collection file, or both?

  - by g3n3rallyl0st

  I have to have multiple classes for this program. The problem is, I don't fully understand arrays and how they work, so I'm a little lost. I will post my program I have written thus far so you can see what I'm working with, but I don't expect anyone to DO my assignment for me. I just need to know where to start and I'll try to go from there. I think I need to use a double array since I will be working with decimals since it deals with money, and my method call needs to calculate total price for all items entered by the user. Please help: RUNNING FILE package inventory2; import java.util.Scanner; public class RunApp { public static void main(String[] args) { Scanner input = new Scanner( System.in ); DataCollection theProduct = new DataCollection(); String Name = ""; double pNumber = 0.0; double Units = 0.0; double Price = 0.0; while(true) { System.out.print("Enter Product Name: "); Name = input.next(); theProduct.setName(Name); if (Name.equalsIgnoreCase("stop")) { return; } System.out.print("Enter Product Number: "); pNumber = input.nextDouble(); theProduct.setpNumber(pNumber); System.out.print("Enter How Many Units in Stock: "); Units = input.nextDouble(); theProduct.setUnits(Units); System.out.print("Enter Price Per Unit: "); Price = input.nextDouble(); theProduct.setPrice(Price); System.out.print("\n Product Name: " + theProduct.getName()); System.out.print("\n Product Number: " + theProduct.getpNumber()); System.out.print("\n Amount of Units in Stock: " + theProduct.getUnits()); System.out.print("\n Price per Unit: " + theProduct.getPrice() + "\n\n"); System.out.printf("\n Total cost for %s in stock: $%.2f\n\n\n", theProduct.getName(), theProduct.calculatePrice()); } } } DATA COLLECTION FILE package inventory2; public class DataCollection { String productName; double productNumber, unitsInStock, unitPrice, totalPrice; public DataCollection() { productName = ""; productNumber = 0.0; unitsInStock = 0.0; unitPrice = 0.0; } //setter methods public void setName(String name) { productName = name; } public void setpNumber(double pNumber) { productNumber = pNumber; } public void setUnits(double units) { unitsInStock = units; } public void setPrice(double price) { unitPrice = price; } //getter methods public String getName() { return productName; } public double getpNumber() { return productNumber; } public double getUnits() { return unitsInStock; } public double getPrice() { return unitPrice; } public double calculatePrice() { return (unitsInStock * unitPrice); } }

• Should enumerators be placed in a separate file or within another class?

  - by Icono123

  I currently have a class file with the following enumerator: using System; namespace Helper { public enum ProcessType { Word = 0, Adobe = 1, } } Or should I include the enumerator in the class where it's being used? I noticed Microsoft creates a new class file for DockStyle: using System; using System.ComponentModel; using System.Drawing.Design; namespace System.Windows.Forms { public enum DockStyle { None = 0, Top = 1, Bottom = 2, Left = 3, Right = 4,. Fill = 5, } }

  Hi, I know i can extract a file's icon using using (System.Drawing.Icon sysicon = System.Drawing.Icon.ExtractAssociatedIcon(filePath)) { icon = System.Windows.Interop.Imaging.CreateBitmapSourceFromHIcon( sysicon.Handle, System.Windows.Int32Rect.Empty, System.Windows.Media.Imaging.BitmapSizeOptions.FromEmptyOptions()); } But how can I extract the icon without a given file?

• Can I use accepts_nested_attributes_for with checkboxes in a _form to select potential 'links' from a list

  - by Ryan

  In Rails 3: I have the following models: class System has_many :input_modes # name of the table with the join in it has_many :imodes, :through => :input_modes, :source => 'mode', :class_name => "Mode" has_many :output_modes has_many :omodes, :through => :output_modes, :source => 'mode', :class_name => 'Mode' end class InputMode # OutputMode is identical belongs_to :mode belongs_to :system end class Mode ... fields, i.e. name ... end That works nicely and I can assign lists of Modes to imodes and omodes as intended. What I'd like to do is use accepts_nested_attributes_for or some other such magic in the System model and build a view with a set of checkboxes. The set of valid Modes for a given System is defined elsewhere. I'm using checkboxes in the _form view to select which of the valid modes is actually set in imodes and omodes . I don't want to create new Modes from this view, just select from a list of pre-defined Modes. Below is what I'm currently using in my _form view. It generates a list of checkboxes, one for each allowed Mode for the System being edited. If the checkbox is ticked then that Mode is to be included in the imodes list. <% @allowed_modes.each do |mode| %> <li> <%= check_box_tag :imode_ids, mode.id, @system.imodes.include?(modifier), :name => 'imode_ids[]' %> <%= mode.name %> </li> <% end %> Which passes this into the controller in params: { ..., "imode_ids"=>["2", "14"], ... } In the controller#create I extract and assign the Modes that had their corresponding checkboxes ticked and add them to imodes with the following code: @system = System.new(params[:system]) # Note the the empty list that makes sure we clear the # list if none of the checkboxes are ticked if params.has_key?(:imode_ids) imodes = Mode.find(params[:imode_ids]) else imodes = [] end @system.imodes = imodes Once again that all works nicely but I'll have to copy that cludgey code into the other methods in the controller and I'd much prefer to use something more magical if possible. I feel like I've passed off the path of nice clean rails code and into the forest of "hacking around" rails; it works but I don't like it. What should I have done?

• Microsoft Templates included in jQuery 1.5!

  - by Stephen Walther

  When I joined the ASP.NET team as the Program Manager for Ajax, the ASP.NET team was working on releasing a new version of the Microsoft Ajax Library. This new version of the Microsoft Ajax Library had several really innovative and unique features such as support for client templates, client data-binding, script dependency management, and globalization. However, we kept hearing the message that our customers wanted to use jQuery when building ASP.NET applications. Therefore, about ten months ago, we decided to pursue a risky strategy. Scott Guthrie sent me to Cambridge to meet with John Resig – the creator of jQuery and leader of the jQuery project – to find out whether Microsoft and jQuery could work together. We wanted to find out whether the jQuery project would be open to allowing Microsoft to contribute the innovative features that we were developing for the Microsoft Ajax Library -- such as client templates and client data-binding -- to the jQuery library. Fortunately, the Cambridge meeting with Resig went well. John Resig was very open to accepting contributions to the jQuery library. Over the next few months, we worked out a process for Microsoft to contribute new features to the open-source jQuery project. Resig and Guthrie appeared on stage at the MIX10 conference to announce that Microsoft would be contributing features to jQuery. It has been a long journey, but I am happy to report success. Today, Microsoft and the jQuery project have announced that three plugins developed by developers on the ASP.NET team – the jQuery Templates, jQuery Data Link, and jQuery Globalization plugins – have been accepted as official jQuery plugins. In addition, the jQuery Templates plugin will be integrated into jQuery 1.5 which is the next major release of jQuery. You can learn more about the plugins by watching the following Web Camps TV episode hosted by James Senior with Stephen Walther: Web Camps TV #5 - Microsoft Commits Code to jQuery! You can read Scott Guthrie’s blog announcement here: http://weblogs.asp.net/scottgu/archive/2010/10/04/jquery-templates-data-link-and-globalization-accepted-as-official-jquery-plugins.aspx You can read the jQuery team’s announcement here: http://blog.jquery.com/2010/10/04/new-official-jquery-plugins-provide-templating-data-linking-and-globalization/ I wrote the original proposal for the jQuery Templates plugin. Dave Reed and Boris Moore were the ASP.NET developers responsible for actually writing the plugin (with lots of input from the jQuery team and the jQuery community). Boris has written a great set of tutorials on the Templates plugin. The first tutorial in his series is located here: http://www.borismoore.com/2010/09/introducing-jquery-templates-1-first.html I want to thank John Resig, Richard Worth, Scott Gonzalez, Rey Bango, Jorn Zaefferer, Karl Swedberg and all of the other members of the jQuery team for working with the ASP.NET team and accepting our contributions to the jQuery project.

• Windows Azure Use Case: Fast Acquisitions

  - by BuckWoody

  This is one in a series of posts on when and where to use a distributed architecture design in your organization's computing needs. You can find the main post here: http://blogs.msdn.com/b/buckwoody/archive/2011/01/18/windows-azure-and-sql-azure-use-cases.aspx  Description: Many organizations absorb, take over or merge with other organizations. In these cases, one of the most difficult parts of the process is the merging or changing of the IT systems that the employees use to do their work, process payments, and even get paid. Normally this means that the two companies have disparate systems, and several approaches can be used to have the two organizations use technology between them. An organization may choose to retain both systems, and manage them separately. The advantage here is speed, and keeping the profit/loss sheets separate. Another choice is to slowly “sunset” or stop using one organization’s system, and cutting to the other system immediately or at a later date. Although a popular choice, one of the most difficult methods is to extract data and processes from one system and import it into the other. Employees at the transitioning system have to be trained on the new one, the data must be examined and cleansed, and there is inevitable disruption when this happens. Still another option is to integrate the systems. This may prove to be as much work as a transitional strategy, but may have less impact on the users or the balance sheet. Implementation: A distributed computing paradigm can be a good strategic solution to most of these strategies. Retaining both systems is made more simple by allowing the users at the second organization immediate access to the new system, because security accounts can be created quickly inside an application. There is no need to set up a VPN or any other connections than just to the Internet. Having the users stop using one system and start with the other is also simple in Windows Azure for the same reason. Extracting data to Azure holds the same limitations as an on-premise system, and may even be more problematic because of the large data transfers that might be required. In a distributed environment, you pay for the data transfer, so a mixed migration strategy is not recommended. However, if the data is slowly migrated over time with a defined cutover, this can be an effective strategy. If done properly, an integration strategy works very well for a distributed computing environment like Windows Azure. If the Azure code is architected as a series of services, then endpoints can expose the service into and out of not only the Azure platform, but internally as well. This is a form of the Hybrid Application use-case documented here.

• Subterranean IL: Filter exception handlers

  - by Simon Cooper

  Filter handlers are the second type of exception handler that aren't accessible from C#. Unlike the other handler types, which have defined conditions for when the handlers execute, filter lets you use custom logic to determine whether the handler should be run. However, similar to a catch block, the filter block does not get run if control flow exits the block without throwing an exception. Introducing filter blocks An example of a filter block in IL is the following: .try { // try block } filter { // filter block endfilter }{ // filter handler } or, in v1 syntax, TryStart: // try block TryEnd: FilterStart: // filter block HandlerStart: // filter handler HandlerEnd: .try TryStart to TryEnd filter FilterStart handler HandlerStart to HandlerEnd In the v1 syntax there is no end label specified for the filter block. This is because the filter block must come immediately before the filter handler; the end of the filter block is the start of the filter handler. The filter block indicates to the CLR whether the filter handler should be executed using a boolean value on the stack when the endfilter instruction is run; true/non-zero if it is to be executed, false/zero if it isn't. At the start of the filter block, and the corresponding filter handler, a reference to the exception thrown is pushed onto the stack as a raw object (you have to manually cast to System.Exception). The allowed IL inside a filter block is tightly controlled; you aren't allowed branches outside the block, rethrow instructions, and other exception handling clauses. You can, however, use call and callvirt instructions to call other methods. Filter block logic To demonstrate filter block logic, in this example I'm filtering on whether there's a particular key in the Data dictionary of the thrown exception: .try { // try block } filter { // Filter starts with exception object on stack // C# code: ((Exception)e).Data.Contains("MyExceptionDataKey") // only execute handler if Contains returns true castclass [mscorlib]System.Exception callvirt instance class [mscorlib]System.Collections.IDictionary [mscorlib]System.Exception::get_Data() ldstr "MyExceptionDataKey" callvirt instance bool [mscorlib]System.Collections.IDictionary::Contains(object) endfilter }{ // filter handler // Also starts off with exception object on stack callvirt instance string [mscorlib]System.Object::ToString() call void [mscorlib]System.Console::WriteLine(string) } Conclusion Filter exception handlers are another exception handler type that isn't accessible from C#, however, just like fault handlers, the behaviour can be replicated using a normal catch block: try { // try block } catch (Exception e) { if (!FilterLogic(e)) throw; // handler logic } So, it's not that great a loss, but it's still annoying that this functionality isn't directly accessible. Well, every feature starts off with minus 100 points, so it's understandable why something like this didn't make it into the C# compiler ahead of a different feature.

• Add Global Hotkeys to Windows Media Player

  - by DigitalGeekery

  Do you use Windows Media Player in the background while working in other applications? The WMP Keys plug-in for Media Player adds global keyboard shortcuts that allow you to control Media Player even when it isn’t in focus. Windows Media Player has a slew of keyboard shortcuts that work only when the media player is active, but these shortcuts stop working once WMP is no longer in focus or minimized. WMP Keys add the following default global hotkeys for Windows Media Player 10, 11, and 12. Ctrl+Alt+Home – Play / Pause Ctrl+Alt+Right – Next track Ctrl+Alt+Left – Previous track Ctrl+Alt+Up Arrow Key – Volume Up Ctrl+Alt+Down Arrow Key – Volume Down Ctrl+Alt+F – Fast Forward Ctrl+Alt+B – Fast Backward Ctrl+Alt+[1-5] – Rate 1-5 stars Note: Tapping Ctrl+Alt+F and Ctrl+Alt+B will skip ahead or back in 5 second intervals. Close out of Windows Media Player and then download and install WMP Keys (link below). After you’ve installed WMP Keys, you’ll need to enable it.

• Control Sysinternals Suite & NirSoft Utilities with a Single Interface

  - by Asian Angel

  Sysinternals and NirSoft both provide helpful utilities for your Windows system but may not be very convenient to access. Using the Windows System Control Center you can easily access everything through a single UI front end. Setup The first thing to do is set up three new folders in Program Files (or Program Files (x86) if you are using a 64bit system) with the following names (the first two need to exactly match what is shown here): Sysinternals Suite NirSoft Utilities (create this folder only if you have any of these apps downloaded) Windows System Control Center (or WSCC depending on your preferences) Unzip the contents of the Sysinternals Suite into its’ folder. Then unzip any individual NirSoft Utilities programs that you have downloaded into the NirSoft folder. All that is left to do is to unzip the WSCC software into its’ folder and create a shortcut. WSCC in Action When you start WSCC up for the first time you will see the following message with a brief explanation about the software. Next the options window will appear providing you an opportunity to look around and make any desired changes. WSCC can access utilities for both suites using a live connection if needed (utilities accessed live are not downloaded). Note: This occurs on the first run only. This is the main WSCC window…you can choose the utility that you want to use by sorting through an all items list or based on category. Note: WSCC may occasionally experience a problem downloading a particular utility if using the live service. We conducted a quick test by accessing two Sysinternals apps. First PsInfo… Followed by DiskView. Both opened quickly and were ready to go. There were no NirSoft Utilities installed on our test system in order to provide a live access example. Within moments WSCC accessed the CurrProcess utility and had it running on our system. Our recommendation is to download your favorite utilities from both suites (in order to always have easy access to them). Conclusion WSCC provides an easy way to access all of the apps in the Sysinternals Suite and NirSoft Utilities in one place. Note: A PortableApps version is also available.

• cannot connect with huawei e173 after upgrade to 12.10 using network manager

  - by user104195

  Since upgrade from 12.04 to 12.10 I can't connect to internet using mobile broadband modem Huawei e173. It worked earlier without problems and now it seems to be properly recognized (at least its connections appear in network manager applet), and after selecting connection manually it starts connection procedure. After about 20 seconds it returns to state disconnected. After browsing internet I've found that running network manager with: NM_PPP_DEBUG=1 /usr/sbin/NetworkManager --no-daemon After inserting modem I get: NetworkManager[507]: <warn> (ttyUSB2): failed to look up interface index NetworkManager[507]: <info> (ttyUSB2): new GSM/UMTS device (driver: 'option1' ifindex: 0) NetworkManager[507]: <info> (ttyUSB2): exported as /org/freedesktop/NetworkManager/Devices/2 NetworkManager[507]: <info> (ttyUSB2): now managed NetworkManager[507]: <info> (ttyUSB2): device state change: unmanaged -> unavailable (reason 'managed') [10 20 2] NetworkManager[507]: <info> (ttyUSB2): deactivating device (reason 'managed') [2] NetworkManager[507]: <info> (ttyUSB2): device state change: unavailable -> disconnected (reason 'none') [20 30 0] where 'failed to look up interface index' seems to be suspicious.

• Oracle’s Sun Server X4-8 with Built-in Elastic Computing

  - by kgee

  We are excited to announce the release of Oracle's new 8-socket server, Sun Server X4-8. It’s the most flexible 8-socket x86 server Oracle has ever designed, and also the most powerful. Not only does it use the fastest Intel® Xeon® E7 v2 processors, but also its memory, I/O and storage subsystems are all designed for maximum performance and throughput. Like its predecessor, the Sun Server X4-8 uses a “glueless” design that allows for maximum performance for Oracle Database, while also reducing power consumption and improving reliability. The specs are pretty impressive. Sun Server X4-8 supports 120 cores (or 240 threads), 6 TB memory, 9.6 TB HDD capacity or 3.2 TB SSD capacity, contains 16 PCIe Gen 3 I/O expansion slots, and allows for up to 6.4 TB Sun Flash Accelerator F80 PCIe Cards. The Sun Server X4-8 is also the most dense x86 server with its 5U chassis, allowing 60% higher rack-level core and DIMM slot density than the competition.  There has been a lot of innovation in Oracle’s x86 product line, but the latest and most significant is a capability called elastic computing. This new capability is built into each Sun Server X4-8.   Elastic computing starts with the Intel processor. While Intel provides a wide range of processors each with a fixed combination of core count, operational frequency, and power consumption, customers have been forced to make tradeoffs when they select a particular processor. They have had to make educated guesses on which particular processor (core count/frequency/cache size) will be best suited for the workload they intend to execute on the server.Oracle and Intel worked jointly to define a new processor, the Intel Xeon E7-8895 v2 for the Sun Server X4-8, that has unique characteristics and effectively combines the capabilities of three different Xeon processors into a single processor. Oracle system design engineers worked closely with Oracle’s operating system development teams to achieve the ability to vary the core count and operating frequency of the Xeon E7-8895 v2 processor with time without the need for a system level reboot.  Along with the new processor, enhancements have been made to the system BIOS, Oracle Solaris, and Oracle Linux, which allow the processors in the system to dynamically clock up to faster speeds as cores are disabled and to reach higher maximum turbo frequencies for the remaining active cores. One customer, a stock market trading company, will take advantage of the elastic computing capability of Sun Server X4-8 by repurposing servers between daytime stock trading activity and nighttime stock portfolio processing, daily, to achieve maximum performance of each workload.To learn more about Sun Server X4-8, you can find more details including the data sheet and white papers here.Josh Rosen is a Principal Product Manager for Oracle’s x86 servers, focusing on Oracle’s operating systems and software. He previously spent more than a decade as a developer and architect of system management software. Josh has worked on system management for many of Oracle's hardware products ranging from the earliest blade systems to the latest Oracle x86 servers.

• Brendan Gregg's "Systems Performance: Enterprise and the Cloud"

  - by user12608550

  Long ago, the prerequisite UNIX performance book was Adrian Cockcroft's 1994 classic, Sun Performance and Tuning: Sparc & Solaris, later updated in 1998 as Java and the Internet. As Solaris evolved to include the invaluable DTrace observability features, new essential performance references have been published, such as Solaris Performance and Tools: DTrace and MDB Techniques for Solaris 10 and OpenSolaris (2006)  by McDougal, Mauro, and Gregg, and DTrace: Dynamic Tracing in Oracle Solaris, Mac OS X and FreeBSD (2011), also by Mauro and Gregg. Much has occurred in Solaris Land since those books appeared, notably Oracle's acquisition of Sun Microsystems in 2010 and the demise of the OpenSolaris community. But operating system technologies have continued to improve markedly in recent years, driven by stunning advances in multicore processor architecture, virtualization, and the massive scalability requirements of cloud computing. A new performance reference was needed, and I eagerly waited for something that thoroughly covered modern, distributed computing performance issues from the ground up. Well, there's a new classic now, authored yet again by Brendan Gregg, former Solaris kernel engineer at Sun and now Lead Performance Engineer at Joyent. Systems Performance: Enterprise and the Cloud is a modern, very comprehensive guide to general system performance principles and practices, as well as a highly detailed reference for specific UNIX and Linux observability tools used to examine and diagnose operating system behaviour.  It provides thorough definitions of terms, explains performance diagnostic Best Practices and "Worst Practices" (called "anti-methods"), and covers key observability tools including DTrace, SystemTap, and all the traditional UNIX utilities like vmstat, ps, iostat, and many others. The book focuses on operating system performance principles and expands on these with respect to Linux (Ubuntu, Fedora, and CentOS are cited), and to Solaris and its derivatives [1]; it is not directed at any one OS so it is extremely useful as a broad performance reference. The author goes beyond the intricacies of performance analysis and shows how to interpret and visualize statistical information gathered from the observability tools.  It's often difficult to extract understanding from voluminous rows of text output, and techniques are provided to assist with summarizing, visualizing, and interpreting the performance data. Gregg includes myriad useful references from the system performance literature, including a "Who's Who" of contributors to this great body of diagnostic tools and methods. This outstanding book should be required reading for UNIX and Linux system administrators as well as anyone charged with diagnosing OS performance issues.  Moreover, the book can easily serve as a textbook for a graduate level course in operating systems [2]. [1] Solaris 11, of course, and Joyent's SmartOS (developed from OpenSolaris) [2] Gregg has taught system performance seminars for many years; I have also taught such courses...this book would be perfect for the OS component of an advanced CS curriculum.

• A Generic Boolean Value Converter

  - by codingbloke

  On fairly regular intervals a question on Stackoverflow like this one:  Silverlight Bind to inverse of boolean property value appears.  The same answers also regularly appear.  They all involve an implementation of IValueConverter and basically include the same boilerplate code. The required output type sometimes varies, other examples that have passed by are Boolean to Brush and Boolean to String conversions.  Yet the code remains pretty much the same.  There is therefore a good case to create a generic Boolean to value converter to contain this common code and then just specialise it for use in Xaml. Here is the basic converter:- BoolToValueConverter using System; using System.Windows.Data; namespace SilverlightApplication1 {     public class BoolToValueConverter<T> : IValueConverter     {         public T FalseValue { get; set; }         public T TrueValue { get; set; }         public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)         {             if (value == null)                 return FalseValue;             else                 return (bool)value ? TrueValue : FalseValue;         }         public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)         {             return value.Equals(TrueValue);         }     } } With this generic converter in place it easy to create a set of converters for various types.  For example here are all the converters mentioned so far:- Value Converters using System; using System.Windows; using System.Windows.Media; namespace SilverlightApplication1 {     public class BoolToStringConverter : BoolToValueConverter<String> { }     public class BoolToBrushConverter : BoolToValueConverter<Brush> { }     public class BoolToVisibilityConverter : BoolToValueConverter<Visibility> { }     public class BoolToObjectConverter : BoolToValueConverter<Object> { } } With the specialised converters created they can be specified in a Resources property on a user control like this:- <local:BoolToBrushConverter x:Key="Highlighter" FalseValue="Transparent" TrueValue="Yellow" /> <local:BoolToStringConverter x:Key="CYesNo" FalseValue="No" TrueValue="Yes" /> <local:BoolToVisibilityConverter x:Key="InverseVisibility" TrueValue="Collapsed" FalseValue="Visible" />

• How to build a 4x game?

  - by Marco

  I'm trying to study how succefully implement a 4x game. Area of interest: 1) map data: how to store stellars systems (graphs?), how to generate them and so on.. 2) multiplayer: how to organize code in a non graphical server and a client to display it 3) command system: what are patters to catch user and ai decisions and handle them, adding at first "explore" and "colonize" then "combat", "research", "spy" and so on (commands can affect ships, planets, research, etc..) 4) ai system: ai can use commands to expand, upgrade planets and ship I know is a big questions, so help is appreciated :D 1) Map data Best choice is have a graph to model a galaxy. A node is a stellar system and every system have a list of planets. Ship cannot travel outside of predefined paths, like in Ascendancy: http://www.abandonia.com/files/games/221/Ascendancy_2.png Every connection between two stellar systems have a cost, in turns. Generate a galaxy is only a matter of: - dimension: number of stellar systems, - variety: randomize number of planets and types (desertic, earth, etc..), - positions of each stellar system on game space - connections: assure that exist a path between every node, so graph is "connected" (not sure if this a matematically correct term) 2) Multiplayer Game is organized in turns: player 1, player 2, ai1, ai2. Server take care of all data and clients just diplay it and collect data change. Because is a turn game, latency is not a problem :D 3) Command system I would like to design a hierarchy of commands to take care of this aspect: abstract Genericcommand (target) ExploreCommand (Ship) extends genericcommand colonizeCommand (Ship) buildcommand(planet, object) and so on. In my head all this commands are stored in a queue for every planets, ships or reasearch center or spy, and each turn a command is sent to a server to apply command and change data state 4) ai system I don't have any idea about this. Is a big topic and what I want is a simple ai. Something like "expand and fight against everyone". I think about a behaviour tree to control ai moves, so I can develop an ai that try to build ships to expand and then colonize planets, upgrade them throught science and combat enemies. Could be done with a finite state machine too ? any ideas, resources, article are welcome!

• Gradle for NetBeans RCP

  - by Geertjan

  Start with the NetBeans Paint Application and do the following to build it via Gradle (i.e., no Gradle/NetBeans plugin is needed for the following steps), assuming you've set up Gradle. Do everything below in the Files or Favorites window, not in the Projects window. In the application directory "Paint Application". Create a file named "settings.gradle", with this content: include 'ColorChooser', 'Paint' Create another file in the same location, named "build.gradle", with this content: subprojects { apply plugin: "announce" apply plugin: "java" sourceSets { main { java { srcDir 'src' } resources { srcDir 'src' } } } } In the module directory "Paint". Create a file named "build.gradle", with this content: dependencies { compile fileTree("$rootDir/build/public-package-jars").matching { include '**/*.jar' } } task show << { configurations.compile.each { dep -> println "$dep ${dep.isFile()}" } } Note: The above is a temporary solution, as you can see, the expectation is that the JARs are in the 'build/public-packages-jars' folder, which assumes an Ant build has been done prior to the Gradle build. Now run 'gradle classes' in the "Paint Application" folder and everything will compile correctly. So, this is how the Paint Application now looks: Preferable to the second 'build.gradle' would be this, which uses the JARs found in the NetBeans Platform... netbeansHome = '/home/geertjan/netbeans-dev-201111110600' dependencies { compile files("$rootDir/ColorChooser/release/modules/ext/ColorChooser.jar") def projectXml = new XmlParser().parse("nbproject/project.xml") projectXml.configuration.data."module-dependencies".dependency."code-name-base".each { if (it.text().equals('org.openide.filesystems')) { def dep = "$netbeansHome/platform/core/"+it.text().replace('.','-')+'.jar' compile files(dep) } else if (it.text().equals('org.openide.util.lookup') || it.text().equals('org.openide.util')) { def dep = "$netbeansHome/platform/lib/"+it.text().replace('.','-')+'.jar' compile files(dep) } else { def dep = "$netbeansHome/platform/modules/"+it.text().replace('.','-')+'.jar' compile files(dep) } } } task show << { configurations.compile.each { dep -> println "$dep ${dep.isFile()}" } } However, when you run 'gradle classes' with the above, you get an error like this: geertjan@geertjan:~/NetBeansProjects/PaintApp1/Paint$ gradle classes :Paint:compileJava [ant:javac] Note: Attempting to workaround javac bug #6512707 [ant:javac] [ant:javac] [ant:javac] An annotation processor threw an uncaught exception. [ant:javac] Consult the following stack trace for details. [ant:javac] java.lang.NullPointerException [ant:javac] at com.sun.tools.javac.util.DefaultFileManager.getFileForOutput(DefaultFileManager.java:1058) No idea why the above happens, still trying to figure it out. Once the above works, we can start figuring out how to use the NetBeans Maven repo instead and then the user of the plugin will be able to select whether to use local JARs or JARs from the NetBeans Maven repo. Many thanks to Hans Dockter who put the above together with me today, via Skype!

• How to integrate Java ME SDK 3.2 with NetBeans

  - by SungmoonCho

  Many people like to use Java ME SDK with IDEs. We provided instructions on how to integrate the SDK with NetBeans through the download page, and also through the release note, however, let me explain it here once again with some screen shots. 1. Download Java ME SDK and NetBeans plugin from here. 2. Install Java ME SDK first. You will have the emulator and the runtime on your machine. Also please unarchive the NetBeans plugin somewhere. 3. Launch NetBeans. 4. Go to "Tools" - "Plugins". 5. Check out the "Installed" tab. Check "Show details". If you see the previous version of Java ME SDK Tools installed already. Check those to uninstall them. 6. Go to "Settings" tab. 7. Click "Add", and provide the location of NetBeans plugin. In my case, it is "file:/C:/Users/sungcho/Downloads/nb-me-sdk-plugins-uc/updates.xml". Don't forget to add "updates.xml" at the end. 8. Click "Okay" 9. Click "Available Plugins" tab. 10. If you scroll down, you will see three Java ME SDK Tools. Check "Java ME SDK Tools" plugin. Also check others as you desire. 11. Follow the instruction and install them. 12. Restart NetBeans 13. That is it. Done. Now you will see Oracle Java ME SDK 3.2 in your Java Platform list.

• Configuring Full-Text Search for pdf and docx files

  - by Lukasz Kurylo

  I think in may I was creating a little filters module based on Full Text-Search. I have configured my dev machine, the same for two testing servers – in our company for internal testing before we deployed it to client, and then on the testing client server. Until last week this build  was still on the testing server and finally we got feedback that we can deploy it on the production one. I only say that, I lost half a day because I had not correctly remembered what I was doing to configure the FTS on the previous servers and I had no notes for that. I foolishly believed in my memory. Lesson learned.   For future reference a bunch of steps to configure the FTS for searching in *.pdf and *.docx files (and by the way in other Office files like *.xlsx).   1. From the page (link) download and install the *.pdf IFilter for FTS. 2. To the PATH global system variable add path to the catalog, where you installed the plugin. Default for this version is: C:\Program Files\Adobe\Adobe PDF iFilter 9 for 64-bit platforms\bin 3. From the page (link) download a FilterPackx64.exe and install it. 4. Now from SSMS execute the following procedures: -sp_fulltext_service 'load_os_resources',1 -sp_fulltext_service 'verify_signature', 0 5. Restart the server 6. Now we must check if the plugins are visible: -select document_type, path from sys.fulltext_document_types where document_type = '.pdf' -select document_type, path from sys.fulltext_document_types where document_type = '.docx' 7. If we see a result, then we can assume that everything is ok*. 8. Right now we can create a catalog for FTS and indexes on appropriate columns.     *I lost a lot of hours to find out, why the plugin for the *.pdf files wasn’t indexed any file in the database, but in the sys.fulltext_document_types table there was available a line for this plugin. After the deeper investigation I found that the *.pdf files actually were indexed. At least the EOF sign was added to the indexes and nothing more for each file. In the end the problem was that, I forgot to add the /bin in the path to the plugin in PATH variable..
