  • using return values from a c# .net made component build as com+

    - by YvesR
    Hello, so far I made a component in C# .NET 4 and use System.EnterpriseServices to make it COM visible. I want to develop business methods in C#, but I still need to access them from classic ASP (vbscript). So far so good, everything works fine (exept function overloading :)). Now I made a test class to get more expirience with return code. using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.EnterpriseServices; using System.Management; namespace iController { /// /// The tools class provides additional functions for general use in out of context to other classes of the iController. /// public class tools :ServicedComponent { #region publich methods public bool TestBoolean() { return true; } public string TestString() { return "this is a string"; } public int TestInteger() { return 32; } public double TestDouble() { return 32.32; } public float TestFloat() { float ret = 2 ^ 16; return ret; } public string[] TestArray() { string[] ret = {"0","1"}; return ret; } public int[][] TestJaggedArray() { int[][] jaggedArray = new int[3][]; jaggedArray[0] = new int[] { 1, 3, 5, 7, 9 }; jaggedArray[1] = new int[] { 0, 2, 4, 6 }; jaggedArray[2] = new int[] { 11, 22 }; return jaggedArray; } public Dictionary<string, string> TestDictionary() { Dictionary<string, string> ret = new Dictionary<string,string>(); ret.Add("test1","val1"); ret.Add("test2","val2"); return ret; } #endregion } } Then I just made a simple vbscript file to run it with cscript.exe for testing porpuse. Dim oTools : Set oTools = CreateObject("iController.tools") WScript.StdOut.WriteLine TypeName(oTools.TestBoolean()) & " - " & oTools.TestBoolean() WScript.StdOut.WriteLine TypeName(oTools.TestString()) & " - " & oTools.TestString() WScript.StdOut.WriteLine TypeName(oTools.TestInteger()) & " - " & oTools.TestInteger() WScript.StdOut.WriteLine TypeName(oTools.TestDouble()) & " - " & oTools.TestDouble() WScript.StdOut.WriteLine TypeName(oTools.TestFloat()) & " - " & oTools.TestFloat() test = oTools.TestArray() WScript.StdOut.WriteLine TypeName(test) WScript.StdOut.WriteLine UBound(test) For i = 0 To UBound(test) WScript.StdOut.WriteLine test(i) Next For Each item IN test WScript.StdOut.WriteLine item Next test = oTools.TestJaggedArray() WScript.StdOut.WriteLine TypeName(test) For Each item IN test WScript.StdOut.WriteLine test & " - " & test.Item(item) Next test = oTools.TestDictionary() WScript.StdOut.WriteLine TypeName(test) For Each item IN test WScript.StdOut.WriteLine test & " - " & test.Item(item) Next What works fine: string, int, foat, double When it comes to array, jaggedarray or dictionaries I get a type mismatch. VarType is 13 object for the dictionary e.g. but this dict seems to be different then the Scripting.Dictionary. I checked codeproject.com and stackoverflow all day and didn't find any hints exept some thread on stackoverflow where someone mentioned there is a need to created a IDispatch interface. So anyone ever had the same issue and can help me or give me some hints I can go on with?

  • What markup languages are good for programming articles/tutorials?

    - by Vilx-
    I very much wish to write a programming tutorial in my native language (Latvian). There are far too few of those. I am however unsure on what markup language to use for writing it. Here are a few things I would like to achieve: The same source can be compiled to both HTML for online viewing and printed form (PDF?). In HTML form it would allow superior interaction and appearance (see below), while the print form would look good on paper (layout etc). I have the idea that the tutorial could be multi-language. Different students have different requirements in their schools. For example, some schools teach Java, some teach C#. You could choose the language on the top of the HTML page and the relevant code snippets (and occasionally pieces of text) would swap out. Most of the text is the same anyway, only the language syntax is a bit different. The text would occasionally contain images too of course and these would need to be included in both the HTML and the printed version In the HTML version the code snippets should get automatic syntax coloring which should ideally be the same as in the recommended IDE for the tutorial. In case there are ambiguities, hints for the syntax colorer should be possible, but I don't want to do the whole coloring by hand. "Output" syntax coloring which would emulate a standard 80x25 text console (since many of the initial programs would be console applicatioins) Collapsible sections for answers to questions (aka "spoiler tags") Automatically generated index/table-of-contents Links to other parts of the tutorial (rendered as links in HTML and as references in print version) "Side note" sections, rendered as separate blocks on the side. Other functions useful in publications that I'm not aware of :) I know this is a bit much to ask, but is there something close enough that I could take it as a starting point and add the necessary features myself? Or is there something in the whole list (like the desire to have both HTML and print versions from the same source) that makes it all fundametally infeasible?

  • Is functional intellisense and code browsing more beneficial than the use of dependency injection containers

    - by Gavin Howden
    This question is really based on PHP, but could be valid for other dynamically typed, interpreted languages and specifically the methods of generating code insight and object browsing in development environments. We use PHPStorm, and find intellisense invaluable, but it is provided by some limited static analysis and parsing of doc comments. Obviously this does not lend well to obtaining dependencies through a container, as the IDE has no idea of the type returned, so the developer loses out on a plethora of (in the case of our framework anyway) rich documentation provided through the doc comments. So we start to see stuff like this: $widget = $dic->YieldInstance('WidgetA', $arg1, $arg2, $arg3, $arg4...)); /** * @var $widget WidgetA */ So that code insight works. In effect the comments are tightly bound, but worse they come out of sync when code is modified but not the comments: $widget = $dic->YieldInstance('WidgetB', $arg1, $arg2, $arg3, $arg4...)); /** * @var $widget WidgetA */ Obviously the comment could be improved by referencing a Widget interface, but then we might as well use a factory and avoid the requirement for the extra typing hints in the comments, and dic complexity / boiler plating. Which is more important to the average developer, code insight / intellisense or 'nirvana' decouplement?

  • Follow point of interest by applying torque

    - by azymm
    Given a body with an orientation angle and a point of interest or targetAngle, is there an elegant solution for keeping the body oriented towards the point of interest by applying torque or impulses? I have a naive solution working below, but the effect is pretty 'wobbly', it'll overshoot each time, slowly getting closer to the target angle - undesirable effect in my case. I'd like to find a solution that is more intelligent - that can accelerate to near the target angle then decelerate and stop right at the target angle (or within a small range). If it helps, I'm using box2d and the body is a rectangle. def gameloop(dt): targetAngle = get_target_angle() bodyAngle = get_body_angle() deltaAngle = targetAngle - bodyAngle if deltaAngle > PI: deltaAngle = targetAngle - (bodyAngle + 2.0 * PI) if deltaAngle < -PI: deltaAngle = targetAngle - (bodyAngle - 2.0 * PI) # multiply by 2, for stronger reaction deltaAngle = deltaAngle * 2.0; body.apply_torque(deltaAngle); One other thing, when body has no linear velocity, the above solution works ok. But when the body has some linear velocity, the solution above causes really wonky movement. Not sure why, but would appreciate any hints as to why that might be.

  • How to make sysctl network bridge settings persist after a reboot?

    - by Zack Perry
    I am setting up a notebook for software demo purpose. The machine has 8GB RAM, a Core i7 Intel CPU, a 128GB SSD, and runs Ubuntu 12.04 LTS 64bit. The notebook is used as a KVM host and runs a few KVM guests. All such guests use the virbr0 default bridge. To enable them to communicate with each other using multicast, I added the following to the host's /etc/sysctl.conf, as shown below net.bridge.bridge-nf-call-ip6tables = 0 net.bridge.bridge-nf-call-iptables = 0 net.bridge.bridge-nf-call-arptables = 0 Afterwards, following man sysctl(8), I issued the following: sudo /sbin/sysctl -p /etc/sysctl.conf My understanding is that this should make these settings persist over reboots. I tested it, and was surprised to find out the following: root@sdn1 :/proc/sys/net/bridge# more *tables :::::::::::::: bridge-nf-call-arptables :::::::::::::: 1 :::::::::::::: bridge-nf-call-ip6tables :::::::::::::: 1 :::::::::::::: bridge-nf-call-iptables :::::::::::::: 1 All defaults are coming back! Yes. I can use some kludgy "get arounds" such as putting a /sbin/sysctl -p /etc/sysctl.conf into the host's /etc/rc.local but I would rather "do it right". Did I misunderstand the man page or is there something that I missed? Thanks for any hints. -- Zack

  • Formating Columns in Excel created by af:exportCollectionActionListener

    - by Duncan Mills
    The af:exportCollectionActionListener behavior in ADF Faces Rich client provides a very simple way of quickly dumping out the contents or selected rows in a table or treeTable to Excel. However, that simplicity comes at a price as it pretty much left up to Excel how to format the data. A common use case where you have a problem is that of ID columns which are often long numerics. You probably want to represent this data as a string, Excel however will probably have other ideas and render it as an exponent  - not what you intended. In earlier releases of the framework you could sort of work around this by taking advantage of a bug which would allow you to surround the outputText in question with invisible outputText components which provided formatting hints to Excel. Something like this: <af:column headertext="Some wide label">  <af:panelgrouplayout layout="horizontal">     <af:outputtext value="=TEXT(" visible="false">     <af:outputtext value="#{row.bigNumberValue}" rendered="true"/>    <af:outputtext value=",0)" visible="false">   </af:panelgrouplayout> </af:column> However, this bug was fixed and so it can no longer be used as a trick, the export now ignores invisible columns. So, if you really need control over the formatting there are several alternatives: First the more powerful ADF Desktop Integration (ADFdi) package which allows you to build fully transactional spreadsheets that "pull" the data and can update it. This gives you all the control that might need on formatting but it does need specific Excel Add-ins on the client to work. For more information about ADFdi have a look at this tutorial on OTN. Or you can of course look at BI Publisher or Apache POI if you're happy with output only spreadsheets

  • Parallel Debugging

    Using Visual Studio 2010 parallel debugging is easy. Two new debugging windows provide a total view of the internals of your PPL and TPL applications with hints on where to start investigations. These are not mere extensions to VS, but tightly integrated with the rest of the debugger experience, so you don't need to learn many new techniques. Use them in your program to eclipse bugs from existence!One of the most FAQ I receive is links to VS2010 parallel debugging content and rather than keep sending many, I decided to gather them all under one permalink, hence this multi link blog post.- MSDN Magazine article on Parallel Debugging.- Screencast of sample code from the article.- MSDN Walkthrough: Debugging a Parallel Application (VB, C++, C#).- Screencast of walkthrough for Parallel Stacks.- Screencast of walkthrough for Parallel Tasks.- MSDN "How To" on Parallel Tasks.- MSDN "How To" on Parallel Stacks.- Detailed blog post on Parallel Tasks.- Detailed blog post on Parallel Stacks.- Detailed blog post on Parallel Stacks - Tasks View.- Detailed blog post on Parallel Stacks - Method View.- Download slides on Parallel Tasks and Parallel Stacks (pptx).If you have questions on these, please post to any of the parallel computing forums or the debugging forum (your question will be routed to me if nobody else can answer it).

  • Gparted resize of an extended partition fails with error "can't have overlapping partitions".

    - by Marcus
    I just decided to install Ubuntu 12.04 alongside Windows 7 on my Dell laptop. However I didn't do this manually but instead used the "Install Ubuntu alongside Windows 7" option during the installation. Now the partition that Ubuntu runs in has very little space and I am getting warning messages. I'm trying to use gparted 0.12.1-5 (via a live CD) to give Windows less space and give Ubuntu more. I've managed to remove 100GB from the Windows partition so I now have some unallocated space between Windows and Ubuntu. This is what it looks like inside Ubuntu (not using the live CD, since it won't let me mount a USB to save a screenshot): So first I take sda4 (extended?) and resize it to the left so it takes up all the unallocated space. Then I resize sda5 (ext4) as well so it takes up all the new space. However, when I hit apply, it fails on the first action (resizing sd4) with the error message can't have overlapping partitions. Any ideas as to why this happens? I also tried resizing sda4 by just a few MB so that it definitely didn't overlap anything, but I still got the same error message. To clarify, I am using gparted from the LiveCD, I just took the screenshot from Ubuntu. I couldn't attach the details file containing the error information from gparted because I can't mount a USB drive when I'm running from the LiveCD. I'm tried following the guide on the gparted website but it says Invalid argument or something like that. If the gparted details are needed, I may need some hints on how to solve the USB issue as well. :)

  • Meta-licensing of applications

    - by Gene
    I'm currently evaluating license management solutions for our customized and project-based applications, which are supported by a single server in the intranet of the customer. The applications use common functionality provided by the server (session handling, data synchronization, management capabilities, etc) and are installed on mobile devices. We allow our customers to run the applications on X devices and want to check on the server, whether the customer sticks to this limit (based on the sessions). We don't want licensing software to be installed on the devices itself (for example providing X serials to the customer) nor do we want to host an additional server for licensing in the intranet of the customer. If a client connects, our server should load the license for the application running on the client and verify, that there are sessions left. The licensing managers I looked at (12 products so far) focus on the application itself and don't allow me to implement such a floating behavior as described above. For example, this software could easily be used to create a "Standard Edition" or a "Professional Edition" of our server software, which is not our intention. In XHEO DeployLX there is a "Session Limit", which allows to limit the license to the currently established sessions in ASP.NET, which comes very close to my needs. I'm currently thinking of implementing a custom solution, which allows me to load and enforce custom-defined licenses per application on the server-side and a simple editor to define such licenses (which would contain a type and the limit itself), but I would appreciate an existing, easy to integrate commercial solution. I think it could be possible to use DeployLX for this task, but I would spend a lot of money for implementing most of the solution myself (except for the editor). Thanks in advance for any suggestions or hints. Gene

  • resolv.conf doesn't get set on reboot when networking is configured for static ip

    - by kenneth koontz
    I'm experiencing, what appears to be a hostname resolution issue in ubuntu 12.04 server edition when configuring my computer to use a static ip. In /etc/network/interfaces: # The primary network interface auto eth0 iface eth0 inet static address 192.168.1.28 netmask 255.255.255.0 gateway 192.168.1.1 Running $ sudo apt-get upgrade, results in a 'Failed to fetch...': . . . W: Failed to fetch http://us.archive.ubuntu.com/ubuntu/dists/precise-backports/universe/i18n/Translation-en_US Something wicked happened resolving 'us.archive.ubuntu.com:http' (-5 - No address associated with hostname) W: Failed to fetch http://us.archive.ubuntu.com/ubuntu/dists/precise-backports/universe/i18n/Translation-en Something wicked happened resolving 'us.archive.ubuntu.com:http' (-5 - No address associated with hostname) E: Some index files failed to download. They have been ignored, or old ones used instead. When I change my /etc/network/interfaces to: auto eth0 iface eth0 inet dhcp Everything works fine. Looking into /etc/resolv.conf provides some more hints...In cases where I was getting the resolving issue, resolve.conf was empty. No nameservers were specified. When I changed to dhcp from static and restarted networking. /etc/resolv.conf gets written to: 'nameserver 192.168.1.1'. Switching back from dhcp to static and restarting doesn't remove the nameserve entry. When I restart the system with static set, resolv.conf is empty. When I restart the system with dhcp set, resolv.conf has nameserver 192.168.1.1. So it appears that the issue is that resolve.conf is not getting written to correctly? Which package/code is responsible for writing to resolv.conf? Is there a particular package that I can take a look at open issues? UPDATE: istream posted a good article discussing changes to resolve.conf in 12.04. http://www.stgraber.org/2012/02/24/dns-in-ubuntu-12-04/

  • Debugging .NET 2.0 assembly from unmanaged code in VS2010?

    - by Rick Strahl
    I’ve run into a serious snag trying to debug a .NET 2.0 assembly that is called from unmanaged code in Visual Studio 2010. I maintain a host of components that using COM interop and custom .NET runtime hosting and ever since installing Visual Studio 2010 I’ve been utterly blocked by VS 2010’s inability to apparently debug .NET 2.0 assemblies when launching through unmanaged code. Here’s what I’m actually doing (simplified scenario to demonstrate): I have a .NET 2.0 assembly that is compiled for COM Interop Compile project with .NET 2.0 target and register for COM Interop Set a breakpoint in the .NET component in one of the class methods Instantiate the .NET component via COM interop and call method The result is that the COM call works fine but the debugger never triggers on the breakpoint. If I now take that same assembly and target it at .NET 4.0 without any other changes everything works as expected – the breakpoint set in the assembly project triggers just fine. The easy answer to this problem seems to be “Just switch to .NET 4.0” but unfortunately the application and the way the runtime is actually hosted has a few complications. Specifically the runtime hosting uses .NET 2.0 hosting and apparently the only reliable way to host the .NET 4.0 runtime is to use the new hosting APIs that are provided only with .NET 4.0 (which all by itself is lame, lame, lame as once again the promise of backwards compatibility is broken once again by .NET). So for the moment I need to continue using the .NET 2.0 hosting APIs due to application requirements. I’ve been searching high and low and experimenting back and forth, posted a few questions on the MSDN forums but haven’t gotten any hints on what might be causing the apparent failure of Visual Studio 2010 to debug my .NET 2.0 assembly properly when called from un-managed code. Incidentally debugging .NET 2.0 targeted assemblies works fine when running with a managed startup application – it seems the issue is specific to the unmanaged code starting up. My particular issue is with custom runtime hosting which at first I thought was the problem. But the same issue manifests when using COM Interop against a .NET 2.0 assembly, so the hosting is probably not the issue. Curious if anybody has any ideas on what could be causing the lack of debugging in this scenario?© Rick Strahl, West Wind Technologies, 2005-2010

  • An introductory presentation about testing with MSTest, Visual Studio, and Team Foundation Server 2010

    - by Thomas Weller
    While it was very quiet here on my blog during the last months, this was not at all true for the rest of my professional life. The simple story is that I was too busy to find the time for authoring blog posts (and you might see from my previous ones that they’re usually not of the ‘Hey, I’m currently reading X’ or ‘I’m currently thinking about Y’ kind…). Anyway. Among the things I did during the last months were setting up a TFS environment (2010) and introducing a development team to the MSTest framework (aka. Visual Studio Unit Testing), some additional tools (e.g. Moq, Moles, White),  how this is supported in Visual Studio, and how it integrates into the broader context of the then new TFS environment. After wiping out all the stuff which was directly related to my former customer and reviewing/extending the Speaker notes, I thought I share this presentation (via Slideshare) with the rest of the world. Hopefully it can be useful to someone else out there… Introduction to testing with MSTest, Visual Studio, and Team Foundation Server 2010 View more presentations from Thomas Weller. Be sure to also check out the slide notes (either by viewing the presentation directly on Slideshare or - even better - by downloading it). They contain quite some additional information, hints, and (in my opinion) best practices.

  • How do I manage the technical debate over WCF vs. Web API?

    - by Saeed Neamati
    I'm managing a team of like 15 developers now, and we are stuck at a point on choosing the technology, where the team is broken into two completely opposite teams, debating over usage of WCF vs. Web API. Team A which supports usage of Web API, brings forward these reasons: Web API is just the modern way of writing services (Wikipedia) WCF is an overhead for HTTP. It's a solution for TCP, and Net Pipes, and other protocols WCF models are not POCO, because of [DataContract] & [DataMember] and those attributes SOAP is not as readable and handy as JSON SOAP is an overhead for network compared to JSON (transport over HTTP) No method overloading Team B which supports the usage of WCF, says: WCF supports multiple protocols (via configuration) WCF supports distributed transactions Many good examples and success stories exist for WCF (while Web API is still young) Duplex is excellent for two-way communication This debate is continuing, and I don't know what to do now. Personally, I think that we should use a tool only for its right place of usage. In other words, we'd better use Web API, if we want to expose a service over HTTP, but use WCF when it comes to TCP and Duplex. By searching the Internet, we can't get to a solid result. Many posts exist for supporting WCF, but on the contrary we also find people complaint about it. I know that the nature of this question might sound arguable, but we need some good hints to decide. We're stuck at a point where choosing a technology by chance might make us regret it later. We want to choose with open eyes. Our usage would be mostly for web, and we would expose our services over HTTP. In some cases (say 5 to 10 percent) we might need distributed transactions though. What should I do now? How do I manage this debate in a constructive way?

  • hdmi AC-3 audio broke after upgrading from 11.10 to 12.04.3

    - by Jim LastName
    I just updated my MythBuntu 11.10 to 12.04.3. Now, when I try to play 5.1 content (ripped DVD), my TV (and receiver) plays a "chattering" sound. I check my receiver and the digital dolby light isn't on--it's in PCM mode. So, either the audio is getting sent as AC-3, but the TV and receiver think it's PCM or the AC-3 audio got converted to multichannel PCM and they can't handle it. My setup: hdmi cable from htpc to TV. TV has an s/pdif output to my receiver. I know TV sends AC-3 audio out correctly because I see digital dolby light come on when I view a digital TV channel and PCM come on when I view an old analog channel. I can connect s/pdif from my htpc to my receiver and the digital dolby light comes on and it can decode the audio just fine. It's just not sending it right over hdmi. Now for some hints to the issue: I noticed in MythTV audio setup when I select alsa:hdmi.... the description only lists 2 channel PCM audio capability. speaker-test -Dhdmi:PCH -c6 errors about a bad channel count (only -c2 works). Finally, I tried vlc and it does the same chattering sound. These all make me think this isn't a MythTV issue, it's something lower than that. I think the best way to troubleshoot this is to start at the drivers and check each layer, one at a time all the way to alsa. I just don't know what the layers are and how to do it. So, I need to find some audio troubleshooting guide to assist me. Or, if one doesn't exist, I'd appreciate some steps. Thanks much, Jim

  • Schedule for my session at MIX10

    - by Laurent Bugnion
    Microsoft has published the schedule for the MIX10 sessions. I have a sweet spot, and I dearly hope that it stays this way (Last year I had a great spot, but it was changed last minute and then I had a much better one, “competing” against Vertigo and their Playboy app… yeah try to explain to a bunch of geeks that MVVM is better than Playboy… good luck with that ;) Anyway, this year my sweet spot is on the very first day of the conference (there are workshops on Sunday, but this qualifies as pre-conference), Monday after the keynote which should get everyone pumped and excited. Schedule and location I would be really happy to meet y’all at Understanding the Model-View-ViewModel Pattern in Lagoon F on Monday at 2:00 PM http://live.visitmix.com/MIX10/Sessions/EX14 See you in Vegas (or in video…) Everything I saw so far hints that this should be a very, very exciting edition of MIX, maybe the most electrifying ever. The great news is that everything will be available even if you cannot make it: The keynotes are typically streamed live, and if you remember last year’s experience at PDC, it is a really good alternative. Built with Silverlight, the feed uses smooth streaming (adjusting the quality according to your bandwidth automatically), possibility to pause and rewind if you miss something, and a great picture quality. As for the sessions, the message at MIX is that the videos will be available online approximately 24 hours after the session is being held. This is a great feat! So, see you in Vegas (or in video)! Cheers, Laurent

  • High load (and high temp) with idle processes

    - by Nanne
    I've got a semi-old laptop (toshiba satellite a110-228), that's appointed 'laptop for the kids' by my sister. I've installed ubuntu netbook (10.10) on it because of the lack-of memory and it seems to work fine, accept from some heat-issues. These where never a problem under windows. It looks like I've got something similar to this problem: Load is generally 1 or higher, sometimes its stuck at 0.80, but its way to high. Top/htop only show a couple of percentage CPU use (which isn't too shocking, as i'm not doing anything). At this point all the software is stock, and i'd like to keep it that way because its supposed to be the easy-to-maintain kids computer. Now I'd like to find out: What could be the cause of the high load? Could it be as this thread implies, some driver, are there other options to check? How could I see what is really keeping the system hot and bothered? How to check what runs, etc etc? I'd like to pinpoint the culprint. further steps to take for debugging? The big bad internet leads me to believe that it might be the graphics drivers. The laptop has an Intel 945M chipset, but that doesn't seem to be one of the problem childs in this manner (I read a lot abotu ATI drivers that need special isntall). I'd not only welcome hints to directly solve this (duh) but also help in starting to debug what is going on. I am really hesitant in installing an older kernel, as I want it to be stock, and easy upgradeable (because I don't live near it, it should run without me ;) ) As an afterthought: to keep the whole thing cooler, can I 'amp up' the fancontrol? Its only going "airplane" mode when the computer is 95 Celcius, which is a tad late for my taste. Top: powertop:

  • how to think like a computer scientist java edition exercise 7.2 [on hold]

    - by James Canfield
    I cannot figure out how to write this program, can someone please help me?! The purpose of this method is to practice manipulating St rings. Create a new program called Name.java. This program will take a name string consisting of EITHER a first name followed by a last name (nonstandar d format) or a last name followed by a comma then a first name (standard format). Ie . “Joe Smith” vs. “Smith, Joe”. This program will convert the string to standard format if it is not already in standard format. Write a method called hasComma that takes a name as an argument and that returns a boolean indicating whether it contains a comma. If i t does, you can assume that it is in last name first format. You can use the indexOf String m ethod to help you. Write a method called convertName that takes a name as an argument. It should check whether it contains a comma by calling your hasComma method. If it does, it should just return the string. If not, then it should assume th at the name is in first name first format, and it should return a new string that contains the name converted to last name comma first format. Uses charAt, length, substring, and indexOf methods. In your main program, loop, asking the user for a n ame string. If the string is not blank, call convertName and print the results. The loop terminat es when the string is blank. HINTS/SUGGESTIONS: Use the charAt, length, substring, and indexOf Str ing methods. Use scanner for your input. To get the full line, complete with spaces, use reader.nextLine()

  • Idea of an algorithm to detect a website's navigation structure?

    - by Uwe Keim
    Currently I am in the process of developing an importer of any existing, arbitrary (static) HTML website into the upcoming release of our CMS. While the downloading the files is solved successfully, I'm pulling my hair off when it comes to detect a site structure (pages and subpages) purely from the HTML files, without the user specifying additional hints. Basically I want to get a tree like: + Root page 1 + Child page 1 + Child page 2 + Child child page1 + Child page 3 + Root page 2 + Child page 4 + Root page 3 + ... I.e. I want to be able to detect the menu structure from the links inside the pages. This has not to be 100% accurate, but at least I want to achieve more than just a flat list. I thought of looking at multiple pages to see similar areas and identify these as menu areas and parse the links there, but after all I'm not that satisfied with this idea. My question: Can you imagine any algorithm when it comes to detecting such a structure? Update 1: What I'm looking for is not a web spider, but an algorithm do create a logical tree of the relationship of the pages to be able to create pages and subpages inside my CMS when importing them. Update 2: As of Robert's suggestion I'll solve this by starting at the root page, and then simply parse links as you go and treat every link inside a page simply as a child page. Probably I'll recurse not in a deep-first manner but rather in a breadth-first manner to get a more balanced navigation structure.

  • NCurses, scrolling of multiline items, "current item" pointer and "selected items"

    - by mjf
    I am looking for hints/ideas for the best (most effective) way on how to scroll multi-line items as well as emphasizing of the "current item" and "selected items" such as: 1 FOO ITEM 1 Foo sub-item 2 Foo sub-item 3 Foo sub-item 2 BAR ITEM 1 Bar sub-item 3 BAZ ITEM 1 Baz sub-item 2 Baz sub-item 4 RAB ITEM 5 ZZZ ITEM 1 Zzz sub-item 2 Zzz sub-item 3 Zzz sub-item 4 Zzz sub-item using NCurses (some combination of windows, sub-windows, pads, copywin? Uff! In fact, the lines could exceed the stdscr's width so that possibility to scroll left/right would be also nice - pads?)... The whole items (including the sub-items) are supposed to be emphasized as full-width window/pad areas. The "current item" (including it's set of lines) should be emphasized (i.e. using A_BOLD), selected set of items of choice (including the set of lines for each the selected item) should be emphasized in another way (i.e. using A_REVERSE). What would you choose to cope with it the most effective NCurses way? (The less redrawals/refreshes the better and terminal is supposed to have the ability to change it's size - such as XTerm running under "floating window" management.) Thank you for your ideas (or perhaps some piece of code where something similar is already solved - I was not able to find anything helpful on the Internet. I mean I am not going to copy/paste foreign code but programming NCurses properly is still somehow difficult to me). P.S.: Would you suggest to "smooth-scroll" +1/-1 screen line or rather "jump-scroll" +lines/-lines of the items? (I personally prefer the latter one.) Sincerely, -- mjf

  • How to find the Fastest DNS servers to host our domain?

    - by Denis Volovik
    The question was born because lately we've seen a pretty odd (well, at least for us, for the first time) - error message in Google webmaster tools - "DNS lookup timeout" ... I was pretty sure that with eNom's 5 DNS servers (dns1... to dns5.name-services.com) we're pretty set... But it appears that from (Europe/Hungary), for example - dns1.name-services.com takes 170ms. to respond on a ping... while GoDaddy's ns75.domaincontrol.com - takes only 40 ms. to respond... and at the same time - dns2 to dns5.name-services.com - each result with a timeout error (on ping)... This issue came to our attention right in the final stages of optimizing our web-site (almost to death) - basically, just in time... I would love to move our domains to a fast (fastest?) and reliable DNS server.. - but how do I find one ? Also - I did the ping tests from various geographic locations (we have servers in many countries) and GoDaddy seemed to be faster than eNom almost in every case. I'd be very thankful for any hints on this! Edited: Well.. maybe this one does not have an answer, after all...
