• NServiceBus Testing Framework and NAnt Issue?

  - by user344775

  Hi Guys, This is my first post here, and I'm new to NService Bus world. After play around for a couple days, and found that it's really powerful framework to creat service and easy to use. :) Now, I came across a small question. I created a project which uses NServiceBus, it got normal message handlers and Saga handlers. And also I created a couple tests around these with NServiceBus.Testing framework. It all works fine when I run the tests via ReSharper Test Runner works and NUnit console, they all works fine, but when I include them into NAnt build script, it throw the following exception: System.Reflection.ReflectionTypeLoadException : Unable to load one or more of the requested types. Retrieve the LoaderExceptions property for more information. at System.Reflection.Module.GetTypesInternal(StackCrawlMark& stackMark) at System.Reflection.Assembly.GetTypes() at NServiceBus.Configure.<c_DisplayClass1.b__0(Assembly a) at System.Array.ForEach[T](T[] array, Action`1 action) at NServiceBus.Configure.With(Assembly[] assemblies) at NServiceBus.Configure.With(String probeDirectory) at NServiceBus.Configure.With() at NServiceBus.Testing.Test.Initialize() Any ideas? Thanks a lot.

• SharePoint 2010: Set Author (CreatedBy) and Editor (ModifiedBy) in SPFile

  - by user1508154

  I am writing a job to migrate documents to SharePoint 2010 and need to set Author and Editor to the original user for the Source System. The way I have done it was dim ImportFile as SPFile dim ImportFolder as SPFolder dim InternalOperatorUser as SPUser ... ImportFile = ImportFolder.Files.Add(ImportFileName, contents, CreatedBy, ModifiedBy, TimeCreated, TimeModified) ... ImportFile.Item("Author") = InternalOperatorUser ImportFile.Item("Editor") = InternalOperatorUser ImportFile.Item.UpdateOverwriteVersion() ImportFile.Item.SystemUpdate(False) ... That is working fine and it is setting Author and Editor on the ListItem level correctly SPFile.Item("Author") SPFile.Item("Editor") BUT (!!!) SharePoint also stores the Editor on the Attachment level which some tools use as display value instead. This value is set to the system user who is running that script SPFile.Versions.Item(1).CreatedBy This field is readonly. Is there a way to modifiy it so I can set InternalOperatorUser to be the Creator for the Attachment as well. SharePoint 2010 Web only uses the values on the ListItem Attribites which are fine but there are thrid party tools that use the ones on the Attahcment level. Using SharePoint Explorer I could confirm that CreatedBy is set to be the system user. Does anyone here know how to change this value as well? Thanks, Wolfgang

• JS: variable inheritance in anonymous functions - scope

  - by tkSimon

  hey guys, someone from doctype sent me here. long story short: var o="before"; x = function() //this needs to be an anonymous function { alert(o); //the variable "o" is from the parent scope }; o="after"; //this chages "o" in the anonymous function x(); //this results in in alert("after"); //which is not the way i want/need it in reality my code is somewhat more complex. my script iterates through many html objects and adds an event listener each element. i do this by declaring an anonymous function for each element and call another function with an ID as argument. that ID is represented by the "o"-variable in this example. after some thinking i understand why it is the way it is, but is there a way to get js to evaluate o as i declare the anonymous function without dealing with the id attribute and fetching my ID from there? my full source code is here: http://pastebin.com/GMieerdw the anonymous function is on line 303

• Can AutoIt scripts run as a scheduled task while not logged in?

  - by muddywater

  I am using Ruby/WATIR/AutoIt to automate a task via Task Scheduler which runs fine as long as I am logged in, but as soon as my account is locked (mandated 10 minute screen lock) or I logout the script stops functioning. When I log back in, it is sitting at the part where AutoIt is supposed to handle a file download dialogue by clicking save and then entering the filename and clicking to save again. The follwing is the code that works while I am logged in. Is AutoIt supposed to work when I am not logged in, and is there some other way to accomplish this? Thanks!! because search has not turned up anything (terms are too generic) prompt_message = "Do you want to save this file, or find a program online to open it?" window_title = "File Download" save_dialog = WIN32OLE.new("AutoItX3.Control") sleep 1 save_dialog_obtained = save_dialog.WinWaitActive(window_title,prompt_message, 25) save_dialog.ControlFocus(window_title, prompt_message, "&Save") sleep 1 save_dialog.Send("S") save_dialog.ControlClick(window_title, prompt_message, "&Save") save_dialog.WinSetTitle(window_title, prompt_message, "This is ForTesting" ) saveas_dialog_obtained = save_dialog.WinWait("Save As", "Save&in", 5) sleep 1 path = fileName puts " Edit the file path" save_dialog.ControlSend("Save As", "", "Edit1",path) sleep 4 puts " Save the file" save_dialog.ControlClick("Save As", "Save &in", "&Save") save_fileAlreadyExists = save_dialog.Send("Y")

• Python - multithreading / multiprocessing, very strange problem.

• Why isn't jQuery automatically appending the JSONP callback?

  - by Aseem Kishore

  The $.getJSON() documentation states: If the specified URL is on a remote server, the request is treated as JSONP instead. See the discussion of the jsonp data type in $.ajax() for more details. The $.ajax() documentation for the jsonp data type states (emphasis mine): Loads in a JSON block using JSONP. Will add an extra "?callback=?" to the end of your URL to specify the callback. So it seems that if I call $.getJSON() with a cross-domain URL, the extra "callback=?" parameter should automatically get added. (Other parts of the documentation support this interpretation.) However, I'm not seeing that behavior. If I don't add the "callback=?" explicitly, jQuery incorrectly makes an XMLHttpRequest (which returns null data since I can't read the response cross-domain). If I do add it explicitly, jQuery correctly makes a <script> request. Here's an example: var URL = "http://www.geonames.org/postalCodeLookupJSON" + "?postalcode=10504&country=US"; function alertResponse(data, status) { alert("data: " + data + ", status: " + status); } $.getJSON(URL, alertResponse); // alerts "data: null, status: success" $.getJSON(URL + "&callback=?", alertResponse); // alerts "data: [object Object], status: undefined" So what's going on? Am I misunderstanding the documentation or forgetting something? It goes without saying that this isn't a huge deal, but I'm creating a web API and I purposely set the callback parameter to "callback" in the hopes of tailoring it nicely to jQuery usage. Thanks!

• jQuery - .Ready fires on div tag not in the page

  - by Anders Juul

  Dear all, I have implemented below function in a separate .js script file which I load in my main page (Asp.net mvc). The call back to server is rather costly but ok if specifically requested on the sub-page / content page on which my div tag needs to be filled. My problem is that the code runs on every page, including pages where the div tag is not present. How can I remedy my code? Any comments welcome, Thanks, Anders, Denmark jQuery("divStatWrapper").ready(function() { jQuery.getJSON("/Statistics/GetPointsDevelopment", function(json) { jQuery("#divStatWrapper #divStatLoading").fadeOut(1000); var jsonPoints = new Array(); jQuery.each(json.Points, function(i, item) { jsonPoints.push(item.PlayerPoints ); }); jsonPoints.reverse(); var api = new jGCharts.Api(); jQuery('<img>') .attr('src', api.make({ data : jsonPoints, type : "lc", size : "600x250" })) .appendTo("#divStatContents"); jQuery("#divStatWrapper #divStatContents").fadeIn(1000); }); });

• How to get around batch file processing limit

  - by Patrick Cuff

  I have a Windows batch file that processes all the files in a given directory. I have 206,783 files I need to process: for %%f in (*.xml) do call :PROCESS %%f goto :STOP :PROCESS :: do something with the file program.exe %1 > %1.new set /a COUNTER=%COUNTER%+1 goto :EOF :STOP @echo %COUNTER% files processed When I run the batch file, the following output is written: 65535 files processed As part of the processing, an output file is created for each file procesed, with a .new extension. When I do a dir *.new it reports 65,535 files exist. So, it appears my command environment has a hard limit on the number of files it can recognize, and that limit is 64K - 1. Is there a way to extend the command environment to manage more than 64K - 1 files? If not, would a VBScript or JavaScript be able to process all 206,783 files? I'm running on Windows 2003 server, Enterprise Edition, 32-bit. UPDATE It looks like the root cause of my issue was with the built-in Windows "extract" command for ZIP files. The files I have to process were copied from another system via a ZIP file. My server doesn't have a ZIP utility installed, just the native Windows commands. I right-clicked on the ZIP file, and did an "Extract all...", which apparently just extracted the first 65,535 files. I downloaded and installed 7-zip onto my server, unzipped all the files, and my batch script worked as intended.

• 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!

• Hyphen vs Dash : Replace Dash with Hyphen

  - by soldieraman

  Alright so we had a problem recently In reporting services some of the String Columns were appearing as gibberish Chinese characters. On further investigation we found it is the hyphen. Well that's what we though first. On further investigation we found it a dash (or en dash) . Basically the reason this has happened is people copy pasting values into this column from word which converts hyphens into dashes automatically. But if you look at the database they both look the same. Though on the application side you can see the difference. How do I replace the dash with a normal hyphen. If you copy the value in put it in SQL server. A hyphen is gray while a dash is black but they both look exactly the same (i.e not bigger or smaller). Problem is I can't write a REPLACE script then (they are the freakin same) REPLACE ('-' with '-') is there a way special characters like the dash can be identified in SQL server? SQL Server v 2005

• Objective-C : Fowler–Noll–Vo (FNV) Hash implementation

  - by Dough

  Hi ! I have a HTTP connector in my iPhone project and queries must have a parameter set from the username using the Fowler–Noll–Vo (FNV) Hash. I have a Java implementation working at this time, this is the code : long fnv_prime = 0x811C9DC5; long hash = 0; for(int i = 0; i < str.length(); i++) { hash *= fnv_prime; hash ^= str.charAt(i); } Now on the iPhone side, I did this : int64_t fnv_prime = 0x811C9DC5; int64_T hash = 0; for (int i=0; i < [myString length]; i++) { hash *= fnv_prime; hash ^= [myString characterAtIndex:i]; } This script doesn't give me the same result has the Java one. In first loop, I get this : hash = 0 hash = 100 (first letter is "d") hash = 1865261300 (for hash = 100 and fnv_prime = -2128831035 like in Java) Do someone see something I'm missing ? Thanks in advance for the help !

• Fastest way to remove non-numeric characters from a VARCHAR in SQL Server

  - by Dan Herbert

  I'm writing an import utility that is using phone numbers as a unique key within the import. I need to check that the phone number does not already exist in my DB. The problem is that phone numbers in the DB could have things like dashes and parenthesis and possibly other things. I wrote a function to remove these things, the problem is that it is slow and with thousands of records in my DB and thousands of records to import at once, this process can be unacceptably slow. I've already made the phone number column an index. I tried using the script from this post: http://stackoverflow.com/questions/52315/t-sql-trim-nbsp-and-other-non-alphanumeric-characters But that didn't speed it up any. Is there a faster way to remove non-numeric characters? Something that can perform well when 10,000 to 100,000 records have to be compared. Whatever is done needs to perform fast. Update Given what people responded with, I think I'm going to have to clean the fields before I run the import utility. To answer the question of what I'm writing the import utility in, it is a C# app. I'm comparing BIGINT to BIGINT now, with no need to alter DB data and I'm still taking a performance hit with a very small set of data (about 2000 records). Could comparing BIGINT to BIGINT be slowing things down? I've optimized the code side of my app as much as I can (removed regexes, removed unneccessary DB calls). Although I can't isolate SQL as the source of the problem anymore, I still feel like it is.

• How to make Chrome redraw SVG dynamically added content?

  - by Adrian

  I've dynamacally added the circle elements to the svg displayed in a iFrame. Chrome isnt showing the new elements, not tried FF yet. Is there somekind of redraw/refresh I need to call? The first circle is actually in the svg document, the rest come from script. <iframe id="svgFrame" src="xmlfile1.svg" width="300" height="300"> <svg xmlns="http://www.w3.org/2000/svg" id="SVG1" width="200" height="200"> <circle cx="20" cy="20" r="5"/> <circle cx="165" cy="80" r="32"/> <circle cx="15" cy="38" r="32"/> <circle cx="140" cy="39" r="30"/> <circle cx="178" cy="32" r="22"/> ...etc <circle cx="166" cy="130" r="16"/> </svg> </iframe> The javascript which creates the elements: function RandomNumber(min, max) { var r; r = Math.floor(Math.random() * (max - min + 1)) + min; return r; } var svg = document.getElementById("svgFrame").contentDocument; for (var i = 0; i < 99; i++) { var n = svg.createElement("circle"); n.setAttribute("cx" , RandomNumber( 0 , 200) ); n.setAttribute("cy" , RandomNumber(0, 200) ); n.setAttribute("r" , RandomNumber(5, 35) ); svg.documentElement.appendChild(n); }

• how do I "ajaxify" my php code?

  - by dot

  I have divs that I want to display at specific times throughout the day. I have it working in PHP, but it requires refreshing the browser manually. I would like my script to automatically load the right div when the time is right. Am I on the right track? Perhaps there is a jquery plugin for this sort of thing that would handle the refreshing? Any help is greatly appreciated... Thanks! <?php $time = date("H\:i"); if (($time > "16:59") && ($time < "18:59")) { echo "<div>1</div>"; } elseif (($time > "18:59") && ($time < "20:59")) { echo "<div>2</div>"; } elseif (($time > "20:59") && ($time < "22:59")) { echo "<div>3</div>"; } else { echo "<div id='out'><p>Outside the specified point in time.</p></div>"; } ?>

• MSBuild 2010 - how to publish web app to a specific location (nant)?

  - by Mr. Flibble

  I'm trying to get MSBuild 2010 to publish a web app to a specific location. I can get it to publish the deployment package to a particular path, but the deployment package then adds it's own path that changes. For example: if I tell it to publish to C:\dev\build\Output\Debug then the actual web files end up at C:\dev\build\Output\Debug\Archive\Content\C_C\code\sawadee\frontend\IPP-FrontEnd\Source\ControllersViews\obj\Debug\Package\PackageTmp And the C_C part of the path changes (not sure how it chooses this part of the path). This means I can't just script a copy from the publish location. I'm using this nant/msbuild command at the moment: <target name="compile" description="Compiles"> <msbuild project="${name}.sln"> <property name="Platform" value="Any CPU"/> <property name="Configuration" value="Debug"/> <property name="DeployOnBuild" value="true"/> <property name="DeployTarget" value="Package"/> <property name="PackageLocation" value="C:\dev\build\Output\Debug\"/> <property name="AutoParameterizationWebConfigConnectionStrings" value="false"/> <property name="PackageAsSingleFile" value="false"/> </msbuild> Any ideas on how to get it to send the web files directly to a specific location?

• Asp.net MVC jQuery Ajax calls to JsonResult return no data

  - by Maslow

  I have this script loaded on a page: (function() { window.alert('bookmarklet started'); function AjaxSuccess(data, textStatus, xmlHttpRequest) { if (typeof (data) == 'undefined') { return alert('Data is undefined'); } alert('ajax success' + (data || ': no data')); } function AjaxError(xmlHttpRequest, textStatus, errorThrown) { alert('ajax failure:' + textStatus); } /*imaginarydevelopment.com/Sfc*/ var destination = { url: 'http://localhost:3041/Bookmarklet/SaveHtml', type: 'POST', success: AjaxSuccess, error: AjaxError, dataType: 'text',contentType: 'application/x-www-form-urlencoded' }; if (typeof (jQuery) == 'undefined') { return alert('jQuery not defined'); } if (typeof ($jq) == 'undefined') { if (typeof ($) != 'undefined') { $jq = $; } else { return alert('$jq->jquerify not defined'); } } if ($jq('body').length <= 0) { return alert('Could not query body length'); } if ($jq('head title:contains(BookmarkletTest)').length > 0) { alert('doing test'); destination.data = { data: 'BookmarkletTestAjax' }; $jq.ajax(destination); return; } })(); when it is run locally in VS2008's cassini the ajax success shows the returned string from Asp.net MVC, when it is run remotely the ajax success data is null. Here's the controller method that is firing both locally and when run remotely: [AcceptVerbs(HttpVerbs.Post | HttpVerbs.Get)] public string SaveHtml(string data) { var path = getPath(Server.MapPath); System.IO.File.WriteAllText(path,data); Console.WriteLine("SaveHtml called"); Debug.WriteLine("SaveHtml called"); //return Json(new { result = "SaveHtml Success" }); return "SaveHtml Success"; } Once i have it working I was going to remove the GET, but currently accessing the SaveHtml method directly from the webbrowser produces the expected results when testing. So there's something wrong in my javascript I believe, because when I step through there with chrome's developer tools, I see the data is null, and the xmlHttpRequest doesn't appear to have the expected result in it anywhere either. I'm loading jquery via http://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js

• Rails Fixtures Don't Seem to Support Transitive Associations

  - by Rick Wayne

  So I've got 3 models in my app, connected by HABTM relations: class Member < ActiveRecord::Base has_and_belongs_to_many :groups end class Group < ActiveRecord::Base has_and_belongs_to_many :software_instances end class SoftwareInstance < ActiveRecord::Base end And I have the appropriate join tables, and use foxy fixtures to load them: -- members.yml -- rick: name: Rick groups: cals -- groups.yml -- cals: name: CALS software_instances: delphi -- software_instances.yml -- delphi: name: No, this is not a joke, someone in our group is still maintaining Delphi apps... And I do a rake db:fixtures:load, and examine the tables. Yep, the join tables groups_members and groups_software_instances have appropriate IDs in, big numbers generated by hashing the fixture names. Yay! And if I run script/console, I can look at rick's groups and see that cals is in there, or cals's software_instances and delphi shows up. (Likewise delphi knows that it's in the group cals.) Yay! But if I look at rick.groups[0].software_instances...nada. []. And, oddly enough, rick.groups[0].id is something like 30 or 10, not 398398439. I've tried swapping around where the association is defined in the fixtures, e.g. -- members.yml -- rick name: rick -- groups.yml -- cals name: CALS members: rick No error, but same result. (Later: Confirmed, same behavior on MySQL. In fact I get the same thing if I take the foxification out and use ERB to directly create the join tables, so: -- license_groups_software_instances -- cals_delphi: group_id: <%= Fixtures.identify 'cals' % software_instance_id: <%= Fixtures.identify 'delphi' $ Before I chuck it all, reject foxy fixtures and all who sail in her and just hand-code IDs...anybody got a suggestion as to why this is happening? I'm currently working in Rails 2.3.2 with sqlite3, this occurs on both OS X and Ubuntu (and I think with MySQL too). TIA, my compadres.

• array retain question

  - by Cosizzle

  Hello, im fairly new to objective-c, most of it is clear however when it comes to memory managment I fall a little short. Currently what my application does is during a NSURLConnection when the method -(void)connectionDidFinishLoading:(NSURLConnection *)connection is called upon I enter a method to parse some data, put it into an array, and return that array. However I'm not sure if this is the best way to do so since I don't release the array from memory within the custom method (method1, see the attached code) Below is a small script to better show what im doing .h file #import <UIKit/UIKit.h> @interface memoryRetainTestViewController : UIViewController { NSArray *mainArray; } @property (nonatomic, retain) NSArray *mainArray; @end .m file #import "memoryRetainTestViewController.h" @implementation memoryRetainTestViewController @synthesize mainArray; // this would be the parsing method -(NSArray*)method1 { // ???: by not release this, is that bad. Or does it get released with mainArray NSArray *newArray = [[NSArray alloc] init]; newArray = [NSArray arrayWithObjects:@"apple",@"orange", @"grapes", "peach", nil]; return newArray; } // this method is actually // -(void)connectionDidFinishLoading:(NSURLConnection *)connection -(void)method2 { mainArray = [self method1]; } // Implement viewDidLoad to do additional setup after loading the view, typically from a nib. - (void)viewDidLoad { [super viewDidLoad]; } - (void)didReceiveMemoryWarning { // Releases the view if it doesn't have a superview. [super didReceiveMemoryWarning]; // Release any cached data, images, etc that aren't in use. } - (void)viewDidUnload { mainArray = nil; // Release any retained subviews of the main view. // e.g. self.myOutlet = nil; } - (void)dealloc { [mainArray release]; [super dealloc]; } @end

• easy_install ReviewBoard [Errno 104] Connection reset by peer

  - by blastthisinferno

  I have a Kubuntu 10.04 VM image and am trying to install ReviewBoard by following The Linux Installation Wiki. When I get to the step to easy_install ReviewBoard, I encounter a problem I cannot find a solution to.

Has anyone encountered a problem like this? If there is any missing information that would help troubleshoot this, please let me know.

• ASP.NET MVC - Parent-Child Table Relation - how to creat Children in MVC (example request)

  - by adudley

  Hi All. In a standard setup of Parent Child relation, lets say Project and Task. Where a Project is made up of lots of Tasks. So in a standard RDB, we have a Project (ID, Name, Deadline) Task (ID, FK_To_Project, Name, Description, isCompleted) this is all very straight forward. We have an MVC View that views Projects, so we get a nice list of all the project Names next to each deadline. Now we want to CREATE a new PROJECT. The Edit view opens, we type a name, say, 'Make a cup of Tea', with tomorrow as the deadline! Still in this view/web page, I would like a list of all the Child Tasks, in a standard list, with Edit, Delete, and a Create/Add Task button too, just below the 'parent table' details. The simplest way to describe this, is the Parents Table Create/Edit view, with the Childes List View Below it. 1) The ideal solution will also allow my Child Table (Tasks) to have Children also (for more complex scenarios) , and so on, and on, and on. 2) If I navigate away from my Created Project, I don’t want all sorts of random stuff laying around, they went away, it’s gone! 3) I’d expect all the same functionality when Editing an existing project. I’m struggling with the ‘Add New Child’, I had a model dialog (jquery) and all was well, but now when editing an existing child/task, I need to populate the Child Edit, which is a pain and will need loads of java script I think :( How can this be achieved in MVC, does anybody have any examples?

• What is the worst programming language you ever worked with? [closed]

  - by Ludwig Weinzierl

  If you have an interesting story to share, please post an answer, but do not abuse this question for bashing a language. We are programmers, and our primary tool is the programming language we use. While there is a lot of discussion about the best one, I'd like to hear your stories about the worst programming languages you ever worked with and I'd like to know exactly what annoyed you. I'd like to collect this stories partly to avoid common pitfalls while designing a language (especially a DSL) and partly to avoid quirky languages in the future in general. This question is not subjective. If a language supports only single character identifiers (see my own answer) this is bad in a non-debatable way. EDIT Some people have raised concerns that this question attracts trolls. Wading through all your answers made one thing clear. The large majority of answers is appropriate, useful and well written. UPDATE 2009-07-01 19:15 GMT The language overview is now complete, covering 103 different languages from 102 answers. I decided to be lax about what counts as a programming language and included anything reasonable. Thank you David for your comments on this. Here are all programming languages covered so far (alphabetical order, linked with answer, new entries in bold): ABAP, all 20th century languages, all drag and drop languages, all proprietary languages, APF, APL (1), AS400, Authorware, Autohotkey, BancaStar, BASIC, Bourne Shell, Brainfuck, C++, Centura Team Developer, Cobol (1), Cold Fusion, Coldfusion, CRM114, Crystal Syntax, CSS, Dataflex 2.3, DB/c DX, dbase II, DCL, Delphi IDE, Doors DXL, DOS batch (1), Excel Macro language, FileMaker, FOCUS, Forth, FORTRAN, FORTRAN 77, HTML, Illustra web blade, Informix 4th Generation Language, Informix Universal Server web blade, INTERCAL, Java, JavaScript (1), JCL (1), karol, LabTalk, Labview, Lingo, LISP, Logo, LOLCODE, LotusScript, m4, Magic II, Makefiles, MapBasic, MaxScript, Meditech Magic, MEL, mIRC Script, MS Access, MUMPS, Oberon, object extensions to C, Objective-C, OPS5, Oz, Perl (1), PHP, PL/SQL, PowerDynamo, PROGRESS 4GL, prova, PS-FOCUS, Python, Regular Expressions, RPG, RPG II, Scheme, ScriptMaker, sendmail.conf, Smalltalk, Smalltalk , SNOBOL, SpeedScript, Sybase PowerBuilder, Symbian C++, System RPL, TCL, TECO, The Visual Software Environment, Tiny praat, TransCAD, troff, uBasic, VB6 (1), VBScript (1), VDF4, Vimscript, Visual Basic (1), Visual C++, Visual Foxpro, VSE, Webspeed, XSLT The answers covering 80386 assembler, VB6 and VBScript have been removed.

• java Processbuilder - exec a file which is not in path on OS X

  - by Jakob

  Okay i'm trying to make ChucK available in exported Processing sketches, i.e. if i export an app from Processing, the ChucK VM binary will be executed from inside the app. So as a user of said app you don't need to worry about ChucK being in your path at all. Right now i'm generating and executing a bash script file, but this way i don't get any console output from ChucK back into Processing: #!/bin/bash cd "[to where the Chuck executable is located]" ./chuck --kill killall chuck # just to make sure ./chuck chuckScript1.ck cuckScriptn.ck then Process p = Runtime.getRuntime().exec("chmod 777 "+scriptPath); p = Runtime.getRuntime().exec(scriptPath); This works but i want to run ChucK directly from Processing instead, but can't get it to execute: String chuckPath = "[folder in which the chuck executable is located]" ProcessBuilder builder = new ProcessBuilder (chuckPath+"/chuck", "test.ck"); final Process process = builder.start(); InputStream is = process.getInputStream(); InputStreamReader isr = new InputStreamReader(is); BufferedReader br = new BufferedReader(isr); String line; while((line = br.readLine()) != null) println(line); println("done chuckin'! exitValue: " + process.exitValue()); Sorry if this is newbie style :D
