• Convert ISO-8859-1 to UTF-8

  - by tau

  I have several documents I need to convert from ISO-8859-1 to UTF-8 (without the BOM of course). This is the issue though. I have so many of these documents (it is actually a mix of documents, some UTF-8 and some ISO-8859-1) that I need an automated way of converting them. Unfortunately I only have ActivePerl installed and don't know much about encoding in that language. I may be able to install PHP, but I am not sure as this is not my personal computer. Just so you know, I use Scite or Notepad++, but both do not convert correctly. For example, if I open a document in Czech that contains the character "ž" and go to the "Convert to UTF-8" option in Notepad++, it incorrectly converts it to an unreadable character. There is a way I CAN convert them, but it is tedious. If I open the document with the special characters and copy the document to Windows clipboard, then paste it into a UTF-8 document and save it, it is okay. This is too tedious (opening every file and copying/pasting into a new document) for the amount of documents I have. Any ideas? Thanks!!!

• How do I convert an NSMutableString to NSString when using Frameworks?

  - by BWHazel

  I have written an Objective-C framework which builds some HTML code with NSMutableString which returns the value as an NSString. I have declared an NSString and NSMutableString in the inteface .h file: NSString *_outputLanguage; // Tests language output NSMutableString *outputBuilder; NSString *output; This is a sample from the framework implementation .m code (I cannot print the actual code as it is proprietary): -(NSString*)doThis:(NSString*)aString num:(int)aNumber { if ([outputBuilder length] != 0) { [outputBuilder setString:@""]; } if ([_outputLanguage isEqualToString:@"html"]) { [outputBuilder appendString:@"Some Text..."]; [outputBuilder appendString:aString]; [outputBuilder appendString:[NSString stringWithFormat:@"%d", aNumber]]; } else if ([_outputLanguage isEqualToString:@"xml"]) { [outputBuilder appendString:@"Etc..."]; } else { [outputBuilder appendString:@""]; } output = outputBuilder; return output; } When I wrote a text program, NSLog simply printed out "(null)". The code I wrote there was: TheClass *instance = [[TheClass alloc] init]; NSString *testString = [instance doThis:@"This String" num:20]; NSLog(@"%@", testString); [instance release]; I hope this is enough information!

• What are the reasons to use dos batch programs in Windows?

  - by DVK

  Question What would be a good (ideally, technical) reason to ever program some non-trivial task in dos batch language on a modern Windows system as opposed to downloading either PowerShell, or ActiveState Perl? To be more specific, I make the following two assumptions for the duration of this question: anyone technical enough to be able to write a medium-complexity batch script is technical enough to install either of the scripting interpreters. Neither of those two present enough of a learning curve for basic batch replacement tasks that said curve would outweigh the pain of doing any remotely-non-trivial task in batch. Notes "You need a batch program for autoexec.bat" is not a valid reason. Your autoexec.bat may consist of simply calling non-batch script. If you disagree with either of my 2 assumptions above, that's fine, and I may be wrong. But my question is specifically "assuming those 2 assumptions are correct, what would be the reason to still stick with batch?" If it makes it easier to suspend disbelief (in case you disagree with me), add in a 3rd assumption that the question is limited to people who already posess at least some modicum of PowerShell or Perl experience. To re-iterate - this is not meant to be a subjective question about how easy it is to learn PSh or ASPerl compared to doing advanced batch coding. That is a separate question that is too subjective to be bothered with in this post. Background: I used to do some fairly complicated batch programming back in the elder days, and remember batch as one of the worst possble programming languages I had encountered. The idea for this question came after seeing a bunch of batch questions on SO, and trying to grok the answer of one of them out of sheer curiosity and giving up in pain after a minute, exclaiming mentally "why would anyone go through this pain instead of doing that in 1 line of Perl?" :) My own plausible answer I assume there may be an an likely DOS-compatible system, which has DOS interpreter but has no compatible PowerShell or Perl... I'm not aware of one but not completely impossible.

• Efficient Multiple Linear Regression in C# / .Net

  - by mrnye

  Does anyone know of an efficient way to do multiple linear regression in C#, where the number of simultaneous equations may be in the 1000's (with 3 or 4 different inputs). After reading this article on multiple linear regression I tried implementing it with a matrix equation: Matrix y = new Matrix( new double[,]{{745}, {895}, {442}, {440}, {1598}}); Matrix x = new Matrix( new double[,]{{1, 36, 66}, {1, 37, 68}, {1, 47, 64}, {1, 32, 53}, {1, 1, 101}}); Matrix b = (x.Transpose() * x).Inverse() * x.Transpose() * y; for (int i = 0; i < b.Rows; i++) { Trace.WriteLine("INFO: " + b[i, 0].ToDouble()); } However it does not scale well to the scale of 1000's of equations due to the matrix inversion operation. I can call the R language and use that, however I was hoping there would be a pure .Net solution which will scale to these large sets. Any suggestions? EDIT #1: I have settled using R for the time being. By using statconn (downloaded here) I have found it to be both fast & relatively easy to use this method. I.e. here is a small code snippet, it really isn't much code at all to use the R statconn library (note: this is not all the code!). _StatConn.EvaluateNoReturn(string.Format("output <- lm({0})", equation)); object intercept = _StatConn.Evaluate("coefficients(output)['(Intercept)']"); parameters[0] = (double)intercept; for (int i = 0; i < xColCount; i++) { object parameter = _StatConn.Evaluate(string.Format("coefficients(output)['x{0}']", i)); parameters[i + 1] = (double)parameter; }

• Accessing Yahoo realtime stock quotes

  - by DVK

  There's a fairly easy way of retrieving 15-minute delayed quotes off of Yahoo! Finance web site ("quotes.csv" API). However, so far I was unable to find any info on how to access real-time quotes. The hang-ups with real-time quotes are: Only available to logged-in user No API Non-obvious how to scrape the info - I'm somewhat convinced they are placed on the page by some weird Ajax call. So I was wondering if anyone had managed to develop a publically available solution to retrieve real-time quotes for a stock from Yahoo! Finance. Notes: Implementation language/framework need is flexible but Perl or Excel is highly preferred. Assume that security is not an issue - I'm willing to supply yahoo userid and pasword, even in cleartext. I'm not 100% hung up on Yahoo - they are merely the only provider of free realtime stock quotes I'm familiar with. if the same thing can be done with Google Finance, I'd be just as happy. This is for a personal project, so scalability/fault tolerance/etc... are not important. I'm looking for a "do the whole retrieval" library ideally, but if I'm pointed to partial solutions (e.g. how to retrieve info from Yahoo's user-logged-in pages; how to scrape realtime quotes from Yahoo's page) I can fill in the blanks. I saw Finance::YahooQuote but it does not seem to allow you to supply log-in information and appears to use the lagging quotes.csv API Thanks!

• Why do I get an error 'Cannot resolve symbol <symbolname>' in ReSharper?

  - by drachenstern

  Using VS2008 and R# 5 I'm running into an odd situation, where on an aspx page I keep getting Cannot resolve symbol 'symbolname' But the code compiles and runs fine. While having a fix for this would be great, I'm just trying to figure out if I'm losing my mind. The CodeFile directive and Inherits directives are fine. If I compile the app or just let devenv sit for a bit it'll go away, but as soon as I save the aspx [via ctrl+s] R# suddenly has trouble with the Inherits attribute and flips out on every method in the page (OnClick etc). // Anonymized of course but otherwise intact <%@ Page AutoEventWireup="true" CodeFile="TestPage.aspx.cs" Inherits="TestPage" Language="C#" MasterPageFile="~/MasterPage.master" Title="Test Page Title" %> This is mostly just a grievance, because since the code compiles it doesn't stop me from doing what I need. I would post a bug report to the JetBrains site but first I would like to know I'm not alone. It could be my machine. Maybe when I roll to VS2010 in a couple weeks this will go away?

• How do you prove your cleverness and programming skills?

  - by Sebi

  Lately, there were a lot of questions related to career planning and how to decide which languages to learn, how to learn new languages and so on. But I was thinking about a way, how do you will proof later that you're really learned something. Ok you can mentione it in your application for a job or in the interview, but by just stating that I was learning e.g. C++ at home, I don't think this will really be very sucessful. So some suggested to create something (homepage, application, whatsoever) to prove that you also can use these skills in practice. But still I'm not really sure if this will provide any benefit, because it would require a very special project to show all your skills and I don't think you can easily invent such a project (that sould also be useful). Others suggested to solve for example the Project Euler questions but still I'm not sure how this will be useful in career-planning. Are you going to mention at your job interview that you solved all this question in the company's favorite programming language?? :D I can't imagine. The reason why I'm asking is that I have some spare time and I would really like to learn some new programming languages (C++ and/or Python if this matters) and I'm looking for a smart way to do is while concurrently assure that it will be useful in my future career. (there are 3-4 companies id like to try to get a job andIi know all of them are using mainly C++/Pyhton...)

• How can I get PowerShell Added-Types to use Added Types

  - by Scott Weinstein

  I'm working on a PoSh project that generates CSharp code, and then Add-Types it into memory. The new types use existing types in an on disk DLL, which is loaded via Add-Type. All is well and good untill I actualy try to invoke methods on the new types. Here's an example of what I'm doing: $PWD = "." rm -Force $PWD\TestClassOne* $code = " namespace TEST{ public class TestClassOne { public int DoNothing() { return 1; } } }" $code | Out-File tcone.cs Add-Type -OutputAssembly $PWD\TestClassOne.dll -OutputType Library -Path $PWD\tcone.cs Add-Type -Path $PWD\TestClassOne.dll $a = New-Object TEST.TestClassOne "Using TestClassOne" $a.DoNothing() "Compiling TestClassTwo" Add-Type -Language CSharpVersion3 -TypeDefinition " namespace TEST{ public class TestClassTwo { public int CallTestClassOne() { var a = new TEST.TestClassOne(); return a.DoNothing(); } } }" -ReferencedAssemblies $PWD\TestClassOne.dll "OK" $b = New-Object TEST.TestClassTwo "Using TestClassTwo" $b.CallTestClassOne() Running the above script gives the following error on the last line: Exception calling "CallTestClassOne" with "0" argument(s): "Could not load file or assembly 'TestClassOne,...' or one of its dependencies. The system cannot find the file specified." At AddTypeTest.ps1:39 char:20 + $b.CallTestClassOne <<<< () + CategoryInfo : NotSpecified: (:) [], MethodInvocationException + FullyQualifiedErrorId : DotNetMethodException What am I doing wrong?

• Height of a html window's content (not just the viewport height)

  - by gatapia

  Hi All, I'm trying to get the height of a html window's content. This is the full height of the content not the visible height. I have had some (very limited) success using: document.getElementsByTagName('html')[0].offsetHeight in FireFox. This however fails in IEs and it fails in Chrome when using absolute positioned elements (http://code.google.com/p/chromium/issues/detail?id=38999). A sample html file that can be used to reproduce this is: <html> <head> <style> div { border:solid 1px red; height:2000px; width:400px; } .broken { position:absolute; top:0; left:0; } .fixed { position:relative; top:0; left:0; } </style> <script language='javascript'> window.onload = function () { document.getElementById('window.height').innerHTML = window.innerHeight; document.getElementById('window.screen.height').innerHTML = window.screen.height; document.getElementById('document.html.height').innerHTML = document.getElementsByTagName('html')[0].offsetHeight; } </script> </head> <body> <div class='fixed'> window.height: <span id='window.height'>&nbsp;</span> <br/> window.screen.height: <span id='window.screen.height'></span> <br/> document.html.height: <span id='document.html.height'></span> <br/> </div> </body> </html> Thanks All Guido Tapia

• Zend_Translate scan translation files

  - by nute

  I've trying to use Zend_Translate from Zend Framework I am using "POEdit" to generate "gettext" translation files. My files are under /www/mysite.com/webapps/includes/locale (this path is in my include path). I have: pictures.en.mo pictures.en.po (I plan on having pictures.es.mo soon) It all works fine if I manually do addTranslation() for each file. However I want to use the automatic file scanning method. I tried both of those: <?php /*Localization*/ require_once 'Zend/Translate.php'; require_once 'Zend/Locale.php'; define('LOCALE','/www/mysite.com/webapps/includes/locale'); if(!empty($_GET['locale'])){ $locale = new Zend_Locale($_GET['locale']); } else{ $locale = new Zend_Locale(); } $translate = new Zend_Translate('gettext', LOCALE, null, array('scan' => Zend_Translate::LOCALE_FILENAME)); if ( $translate->isAvailable( $locale->getLanguage() ) ){ $translate->setLocale($locale); } else{ $translate->setLocale('en'); } And this: <?php /*Localization*/ require_once 'Zend/Translate.php'; require_once 'Zend/Locale.php'; define('LOCALE','/www/mysite.com/webapps/includes/locale'); if(!empty($_GET['locale'])){ $locale = new Zend_Locale($_GET['locale']); } else{ $locale = new Zend_Locale(); } $translate = new Zend_Translate('gettext', LOCALE); if ( $translate->isAvailable( $locale->getLanguage() ) ){ $translate->setLocale($locale); } else{ $translate->setLocale('en'); } In both cases, I get a Notice: No translation for the language 'en' available. in /www/mysite.com/webapps/includes/Zend/Translate/Adapter.php on line 411 It also worked if I tried to do directory scanning.

• How to Put Javascript into an ASP.NET MVC View

  - by Maxim Z.

  I'm really new to ASP.NET MVC, and I'm trying to integrate some Javascript into a website I'm making as a test of this technology. My question is this: how can I insert Javascript code into a View? Let's say that I start out with the default ASP.NET MVC template. In terms of Views, this creates a Master page, a "Home" View, and an "About" view. The "Home" View, called Index.aspx, looks like this: <%@ Page Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage" %> <asp:Content ID="indexTitle" ContentPlaceHolderID="TitleContent" runat="server"> Home Page </asp:Content> <asp:Content ID="indexContent" ContentPlaceHolderID="MainContent" runat="server"> <h2><%= Html.Encode(ViewData["Message"]) %></h2> <p> To learn more about ASP.NET MVC visit <a href="http://asp.net/mvc" title="ASP.NET MVC Website">http://asp.net/mvc</a>. </p> <p>Welcome to this testing site!</p> </asp:Content> Adding a <script> tag here didn't work. Where and how should I do it? P.S.: I have a feeling I'm missing something very basic... Thanks in advance!

• consistency of Trigger Procedure (before row trigger) Postgresql

  Using Postgresql. I try to use TRIGGER procedure to make some consistency check on INSERT.

• Roadmap to Android development

  - by Matthew

  Hello, I've done a little research, and am interested in developing for Android. I've never programmed before, and have no idea how to go from zero experience to developing for a mobile device. My interest is in eventually making some sort of 2d game. Is there a lesson plan for starting from the ground up? I would think one would need to learn the Java language to start. Looking at the Sun website, it's a bit daunting. Is there a book, specifically, that would wrap up this knowledge in a bit of a directed lesson plan? I'm not sure if opengl-es is what would be required for 2d games. I've done a little research on this, and it's even far more daunting than Java itself. I can't even begin to figure out where to start with even just opengl, sans -es. My best guess would be that I need further knowledge in Java to continue with this, but even still, is it possible to learn concurrently with Java?

• Jquery cookie plugin - conditional content determined by cookie being set

  - by Dave

  Hello I have a sign up form that is displayed to all new site visitors. If a user fills out the form, the next time they visit the site, I would like to display a "welcome back" message where the form would usually sit. I am trying to do this via the jquery cookie plugin (http://plugins.jquery.com/project/Cookie). My form would look like this: <div id="sign_up_form_wrapper"><form id="sign_up" action="" method="POST" name="form"> <input type="checkbox" name="checkbox" id="checkbox" value="1">&nbsp; I accept the terms and conditions</a> <br /><br /><input type="submit" value="ENTER"> </form></div> And I am setting my cookie here: <script type="text/javascript" language="javascript"> $().ready(function() { $('#sign_upm').submit(function(e) { e.preventDefault(); if ($('#sign_up input[name=checkbox]').is(':checked')) { $.cookie('agreed_to_terms', '1', { path: '/', expires: 999999 }); } }); }); </script> That will set the cookie when a user has checked the box, but now I need to do somehting like this: if the cookie has been set, do this: <div id="sign_up_form_wrapper"> <p>Welcome back, John</p> </div> otherwise do this: <div id="sign_up_form_wrapper"> <!-- full form code here --> </div> Any ideas or pointers would be very appreciated, thanks.

• Using HtmlAnchor for anchor tag that navigates in-page named anchor

  - by Frank Schwieterman

  I am trying to render a simple hyperlink that links to a named anchor within the page, for example: <a href="#namedAnchor"scroll to down</a <a name="namedAnchor"down</a The problem is that when I use an ASP.NET control like asp:HyperLink or HtmlAnchor, the href="#namedAnchor" is rendered as href="controls/#namedAnchor" (where controls is the subdirectory where the user control containing the anchor is). Here is the code for the control, using two types of anchor controls, which both have the same problem: <%@ Control Language="C#" AutoEventWireup="true" CodeBehind="Test.ascx.cs" Inherits="TestWebApplication1.controls.Test" % <a href="#namedAnchor" runat="server"HtmlAnchor</a <asp:HyperLink NavigateUrl="#namedAnchor" runat="server"HyperLink</asp:HyperLink The generated source looks like: <a href="controls/#namedAnchor"HtmlAnchor</a <a href="controls/#namedAnchor"HyperLink</a I really just want: <a href="#namedAnchor"HtmlAnchor</a <a href="#namedAnchor"HyperLink</a I am using the HtmlAnchor or HyperLink class because I want to make changes to other attributes in the code behind. I do not want to introduce a custom web control for this requirement, as the requirement I'm pursuing is not that important and it would be hard to talk the team into abandoning the traditional ASP.NET link controls. It seems like I should be able to use the ASP.NET link controls to generate the desired link.

• What do I do about recurring billing?

  - by phidah

  This might be a subjective question, but I'll give it a go. There are already a number of questions on SO that revolves around subscription billing management. I am currently working on a SaaS solution that will require a fully automated billing system. What I am not looking for when asking this question is not advice on implementing towards a specific payment gateway or stuff like that. Instead I'd like advice on what kind of approach to take. The functionality that I need is a system that can handle upgrades, downgrades, recurring billing, cancellations, etc. Initially for one product only, but it might over time be a requirement that the system can handle multiple products (by products I mean fundamentally different products, not different variations of the same product). As I see it there are a number of possible approaches when you need a solution like this: Code a billing server yourself that supports this and is decoupled from each product so that it can handle multiple independent products. Use a hosted solution like Recurly, Chargify, Spreedly or CheddarGetter. The advantage of using a hosted solution is obviously that you don't need PCI certification, the concern is outsourced and it is a lot faster to get up and running. These advantages come at a cost however: The most important support function for your product - i.e. the billing is not in your control. Additionally you have less control and flexibility. What would you do? If we look beyond the PCI requirements I would definately prefer to have a system coded in-house that could do this kind of job. On the other hand I've heard from numerous sources that coding a system like this is a pain. Any advice is highly appreciated. Also, if you advice to code it yourself, any experiences on how to do it or if there are any opensource projects (no matter the language, what I'm after is not the code but the structure) that I can benefit from would really mean alot. Thanks in advance for your inputs! :-)

I have successfully installed tomcat and jdk using following script !define PRODUCT_NAME "App Deploy" !define PRODUCT_VERSION "1.0" !define PRODUCT_PUBLISHER "ZippySoft" SetCompressor lzma ;!include "UserManagement.nsh" ; MUI 1.67 compatible ------ !include "MUI.nsh" ; MUI Settings !define MUI_ABORTWARNING ;!define MUI_ICON "${NSISDIR}\Contrib\Graphics\Icons\modern-install.ico" ; Welcome page !insertmacro MUI_PAGE_WELCOME ; Components page !insertmacro MUI_PAGE_COMPONENTS ; Instfiles page !insertmacro MUI_PAGE_INSTFILES ; Finish page !insertmacro MUI_PAGE_FINISH ; Language files !insertmacro MUI_LANGUAGE "English" ; Reserve files !insertmacro MUI_RESERVEFILE_INSTALLOPTIONS ; MUI end ------ Name "${PRODUCT_NAME} ${PRODUCT_VERSION}" OutFile "AppDeploy.exe" InstallDir "$PROGRAMFILES\App Deploy" ShowInstDetails show ;Section -SETTINGS ; SetOutPath "$INSTDIR" ; SetOverwrite ifnewer ;SectionEnd ;Section "JDK" SEC01 ; File "Prerequisites\jdk-1_5_0_15-windows-i586-p.exe" ; ExecWait "$INSTDIR\jdk-1_5_0_15-windows-i586-p.exe" ;SectionEnd ;System::Call 'Kernel32::SetEnvironmentVariableA(t, t) i("name", "value").r0' ;StrCmp $0 0 error ; ExecWait ProgThatReadsEnv.exe ; Goto done ;error: ; MessageBox MB_OK "Can't set environment variable" ;done: ;Section "Tomcat" SEC02 ; File "Prerequisites\apache-tomcat-6.0.16.exe" ; ExecWait "$INSTDIR\apache-tomcat-6.0.16.exe" ;SectionEnd Section "Data Submission Tool" SEC03 File "Prerequisites\DataSubmissionToolFinal.war" CopyFiles `$INSTDIR\DataSubmissionToolFinal.war` `c:\DataSubmissionToolFinal.war` StrCpy $0 "$INSTDIR\DataSubmissionToolFinal.war" ;Path of copy file from StrCpy $1 "c:\DataSubmissionToolFinal.war" ;Path of copy file to StrCpy $2 1 ; only 0 or 1, set 0 to overwrite file if it already exists System::Call 'kernel32::CopyFile(t r0, t r1, b r2) l' Pop $0 ; pops a bool. if overwrite is off and there is a file then error will be 1 SectionEnd There are no script errors but war file is not getting copied to c drive . How to do it? Also is it possible to identify path to JDK and Tomcat installation using NSIS ? Sorry if the question is too obvious, I am quite new to NSIS..

• iCal file that will update the attendee list?

  - by Peyton Manning

  So I want to add an iCal file to a web page, so that people can add an event to their calendars. But when I view the event in my calendar (Outlook 2007) I want to see everyone who will be attending. How can I do that? I just started experimenting with this, I used Outlook's Save As to create an iCal file for a single event. That works, I can link to that file and other people can add the event to their calendars. But it doesn't tell me who has added it. Here is the (Outlook-generated) code: BEGIN:VCALENDAR PRODID:-//Microsoft Corporation//Outlook 12.0 MIMEDIR//EN VERSION:2.0 METHOD:PUBLISH X-MS-OLK-FORCEINSPECTOROPEN:TRUE BEGIN:VEVENT CLASS:PUBLIC CREATED:20100413T175736Z DESCRIPTION:I want to see if the attendee list is updated when someone adds this event.\n DTEND:20100421T153000Z DTSTAMP:20100413T175736Z DTSTART:20100421T150000Z LAST-MODIFIED:20100413T175736Z LOCATION:Wherever PRIORITY:5 SEQUENCE:0 SUMMARY;LANGUAGE=en-us:Totally fake event TRANSP:OPAQUE UID:040000008200E00074C5B7101A82E00800000000604A0119F8DACA01000000000000000 0100000004D19467F69BF6041A0B0FAFFECA1864B X-ALT-DESC;FMTTYPE=text/html:\n\n\n\n\n\n\n\n\nI want to see if the attendee list is updated when someone adds this e vent.\n\n\n X-MICROSOFT-CDO-BUSYSTATUS:BUSY X-MICROSOFT-CDO-IMPORTANCE:1 X-MICROSOFT-DISALLOW-COUNTER:FALSE X-MS-OLK-ALLOWEXTERNCHECK:TRUE X-MS-OLK-AUTOFILLLOCATION:FALSE X-MS-OLK-CONFTYPE:0 BEGIN:VALARM TRIGGER:-PT15M ACTION:DISPLAY DESCRIPTION:Reminder END:VALARM END:VEVENT END:VCALENDAR

• Problem creating simple "windows script components" on Windows 7.

  - by Bigtoe

  Hi folks, I'm trying to get a Windows Script Component working on and x64 development machine. Works fine on x32 bit. But can't seem to get it running, I have the same problem with both JScript and VBScript. Here's the most simple wsc component possible. All that it does it pop up "Hello" in a message box. If you save the snippit below to a file called test_lib.wsc, you'll then be able to right click and register it. It's now available as a COM Component. <?xml version="1.0"?> <component> <?component error="true" debug="true"?> <registration description="Test Script Library" progid="TestScript.Lib" version="1.00" classid="{314042ea-1c42-4865-956f-08d56d1f00a8}" > </registration> <public> <method name="Hello"> </method> </public> <script language="VBScript"> <![CDATA[ Option Explicit Function Hello() MsgBox("Hello.") End Function ]]> </script> </component> Next create the following sample vb-script and save it to a file called test.vbs dim o set o = createobject("TestScript.Lib") o.hello() When I run the test.vbs with cscript or wscript I always get the following. "C:\test.vbs(3, 1) Microsoft VBScript runtime error: ActiveX component can't create object: 'TestScript.Lib'" This works perfectly fine on a 32 bit XP. Anyone got any ideas about what could be wrong? Thanks a bunch Noel.

• What is the difference between the Lego Mindstorms 1.0 and 2.0

  - by Gavimoss

  I am thinking about buying a mindstorms kit (I don't currently own one but I have used 1.0 at university) and I am a bit unsure as to the benefits of 2.0 over 1.0. I have seen other posts on the subject all saying generally 2.0 is better but I have some more specific questions about this that I can't seem to find any answers on. Apart from the different lego pieces and sensors you get with the 2.0 kit, is there any difference between a 1.0 nxt brick and 2.0 nxt brick? From what I can determine from other sources, they are the same except for the firmware installed. Am I right in saying I could buy a 1.0 kit and install the same firmware that comes with the 2.0 kit and the bricks would be the same or is the 1.0 brick not compatible with the 2.0 firmware??? Also, I plan to use a different programming language like c or java so I need to install specific firmware for that anyway like librcx or lejos right? So if using c or java as opposed to the provided lego coding methods it doesn't matter if I am using 1.0 or 2.0 (except for the lego pieces in the kit) am I right? In a nutshell, assuming I am using librcx or lejos and I don't care about the sensors and lego pieces included, is there any benefit to buying a 2.0 kit over the 1.0 kit? Thanks in advance
