• Batch : list all the subfiles with their absolute path

  - by subtenante

  I want to generate a classpath automatically with al the *.jar files contained under my lib folder. I can't find a way to list all these files with their absolute path, so that I can build my classpath variable. It seems the dir command do not allow to get the absolute path, even when you go recursively with a /s. Basically what I had in mind was something like : set classpath = ./conf for %%i in (`dir /s /withaboslutepath *.jar`) do set classpath = %classpath%;"%%x" Is there a way to achieve this ?

• NetBeans Web-Services Client Project - repeated WSDL parsing

  - by RedGrittyBrick

  I created a new project thus ... File, New Project... Java, Java Application. Right-click project icon in "Projects" tree-view panel. Choose New, Web Service Client... Specify WSDL file e.g. ( ) Project (*) Local file D:\temp\Foo\Bar.wsdl ( ) WSDL URL [Set Proxy...] client-style JAX-WS [ ] Generate Dispatch code It parsed the WSDL and generated lots of java files. I created a main class and used Netbeans to insert a WS client call Now whenever I run my code (Desktop app), it again parses the WSDL (which doesn't ever change) and regenerates about 78 java files and compiles them. How do I stop Netbeans performing this uneccessary and time-consuming action?

• Using LaTeX, how can I have a list of references at the end of each section?

  - by celenius

  I want to generate the bibliography for each section, and have it at the end of the section. When I do this at the moment it generates the full bibliography and places it after each section. Is there a way that this can be done? The advice here says "The chapterbib package provides an option sectionbib that puts the bibliography in a \section* instead of \chapter*, something that makes sense if there is a bibliography in each chapter. This option will not work when natbib is also loaded; instead, add the option to natbib. " I don't understand what this means, and I've tried experimenting with what I thought the options are. Specifically, what does "add the option to natbib" mean? Thank you for your help.

• Fossil gpg workflow for teams

  - by Alex_coder

  I'm learning fossil and trying to reproduce a workflow for two people modifying the same source code tree. So, Alice and Bob both have local repositories of some source code. Both have autosync off. Alice hacks some more, does some commits signing check-ins with her gpg key. This part is fine, as Alice I've managed to generate gpg keys, fossil asked me the key password when commiting. I'm also aware of gpg-agent but don't use it yet, because I'm trying to keep things as simple as possible for now. Now, at some point Bob pulls changes from Alice's fossil repo. How would he verify Alice's signed check-ins?

• How to set probability for a targetSprite shooting accuracy in shooting game ?

  - by srikanth rongali

  Hi, My code is ion cocos2D. I have written code for generating the bullets from the enemy gun for every 0.3seconds. The enemySprite is in right side of the screen in (land scape mode) at winSize.height/2. the bullet starts from the same point and reach the player's end. I used rand() to generate y-coordinate for the bullet to hit on player side. Now, if the bullet bounded rectangle meets the player bounded rectangle the enemy won. If it misses enemy shoots again after 0.3 seconds. Every thing is fine up to here for me. But I have 10 enemies and each have accuracy of hitting player of probabilities ranging from 0.80 to 1.0. First enemy probability is .80 and 10 enemy's is 1.0. How can I adjust the probability for enemy such that it runs according to its probability. Player also hits the enemy.

• TinyMCE or HTML5's contentEditable attribute?

  - by Mike

  I have always hated wysiwyg editors but most of the applications I develop they are necessary for our clients to edit their content. After trying out a few different ones I seemed to like tinyMCE the best. Although powerful and seems to generate fairly good HTML it is not without its issues. Recently I have been thinking about creating a custom wysiwyg that suits my needs perfectly taking advantage of the contentEditable attribute. Is this HTML5 feature ready? Will I have many cross browser issues? What are its limitations? I guess my question finally boils down to; Will it be worth throwing in the towel on 3rd party wysiwygs and moving to contentEditable regions?

• Writing an app with Perl and Ruby?

  - by Jeff Erickson

  I am working on a project that is mostly Ruby on Rails. However, I need to generate and parse Excel files in this project (I know, I know...), so I've been using Perl's Spreadsheet::WriteExcel and Spreadsheet::ParseExcel which work well. However, what is the best way to combine this use of Perl with the larger Ruby on Rails app? Is calling the Perl script with backticks the kosher way to go about this? It feels a little hacky to me, but if that is the only (or best) way, then that's what I'll do. I wanted to reach out and see if anyone else has some suggestions or advise. Thank you!

• Urlredirect in MVC2

  - by Ken

  In global.asax routes.MapRoute( "Test_Default", // Route name "test/{controller}/{action}", // URL with parameters new { } ); routes.MapRoute( "Default", "{universe}", new { controller = "notfound", action = "error"} ); I have a controller: Home, containing an action: Index Enter the url in browser: h**p://localhost:53235/test/home/index Inside the index.aspx view in <body> tag: I want to link to the second route. <%=Html.RouteLink("Link", new { universe = "MyUniverse" })%> Shouldn't this generate a link to the second route in Global.asax? The generated url from the above is: h**p://localhost:53235/test/home/index?universe=MyUniverse. I can only get it to work, if I specify the name of the route: <%=Html.RouteLink("Link", "default", new { universe = "MyUniverse" })%> Am I missing something?

• raising a vb6 event using interop

  - by Steve

  Hi, I have a legacy VB6 component that I've imported into VS using tlbimp.exe to generate my interop assembly. The VB6 component defines an event that allows me to pass messages within VB6. Public Event Message(ByVal iMsg As Variant, oCancel As Variant) I would really like to be able to raise this even in my C# program, but its getting imported as an event, not a delegate or something else useful. So, I can only listen, but never fire. Does anyone know how to fire an event contained within VB6? The C# event looks like [TypeLibType(16)] [ComVisible(false)] public interface __MyObj_Event { event __MyObj_MessageEventHandler Message; } I unfortunately cannot change the VB6 code. Thanks.

• phpDocumentor alternative consuming less memory

  - by Michal Cihar

  Okay, I'm fed up with phpDocumentator. It consumes way much more memory and time than I'm willing to give it. Does there exist some really compatible program to generate documentation for PHP code? I've tried PHPDoctor, which looks nice, but it has some missing features. I've also tried PhpDocGen, but it just bails out with some Perl errors, which I'm too lazy to study. Doxygen also does not seem to play well with our sources. PS: The documentation would be for phpMyAdmin, a little bit outdated documentation is here.

• How to View Android Native Code Profiling?

  - by David R.

  I started my emulator with ./emulator -trace profile -avd emulator_15. I then tracked down the trace files to ~/.android/avd/rodgers_emulator_15.avd/traces/profile, where there are six files: qtrace.bb, qtrace.exc, qtrace.insn, qtrace.method, qtrace.pid, qtrace.static. I can't figure out what to do with these files. I've tried both dmtracedump and traceview on all of the files, but none seem to generate any output I can do anything with. How can I view the proportion of time taken by native method calls on Android?

• Creating a customized video using Flash and XML

  - by Aaron Ladage

  The problem: I have to create a Flash video (in CS3) that will query a MySQL database and display that data at certain points in the video. The bigger problem: I'm not a Flash/ActionScript developer, so this is all very foreign to me! I've divided this project into two parts: a.) dynamically generate an XML feed from the data using PHP (using an ID number passed in the URL's query string), and b.) be able to work with it in Flash. I've got the first part working, but am pretty lost in Flash. I can parse the XML, but I'm not sure how to set the data up as variables and attach it to a video's cue points. Can anyone point me in the direction of a good tutorial or offer some advice?

• Using Cepstrum for PDA

  - by CziX

  Hey, I am currently deleveloping a algorithm to decide wheather or not a frame is voiced or unvoiced. I am trying to use the Cepstrum to discriminate between these two situations. I use MATLAB for my implementation. I have some problems, saying something generally about the frame, but my currently implementation looks like (I'm award of the MATLAB has the function rceps, but this haven't worked for either): ceps = abs(ifft(log10(abs(fft(frame.*window')).^2+eps))); Can anybody give me a small demo, that will convert the frame to the power cepstrum, so a single lollipop at the pitch frequency. For instance use this code to generate the frequency. fs = 8000; timelength = 25e-3; freq = 500; k = 0:1/fs:timelength-(1/fs); s = 0.8*sin(2*pi*freq*k); Thanks.

• Video Synthesis - Making waves, pattern, gradients...

  - by Nathan

  I'm writing a program to generate some trippy visuals. My code paints each pixel with a random blue value which loops at 0.04 second intervals. for (y = 0; y < 5.5; y += 0.2) { for (x = 0; x < 7.5; x += 0.2) { b = rand() / ((double) RAND_MAX); setPixelColor(x,y,r,g,b); } } I'd like to do more than just make blue noise... but my maths is a bit rusty, and Google isn't helping me much today, so it would be great if you could share anything you know about making waves, patterns, gradient animations, etc or links to such material.

• How to avoid manual editing of manifest file

  - by Atara

  My application uses isolated activeX (outer), that depends on another activeX (inner), both are using registration-free-com. The generated manifest file contains only the information for the outer activeX. (probably because vs cannot know that the outer activeX is using inner activeX ) When I re-build my project, I always need to manually add the information for the inner activeX to the manifest file, otherwise the application only shows the outer, without the inner. Is there a way to inform visual studio (2008) that I do not want it to re-generate the manifest file for each build? Will I have such option if I upgrade to VS2010 ? Thanks, Atara

• Android programmatically add buttons to layout from string array

  - by Luke Batley

  Does anyone know how to programatically add buttons to the layout from an array? I have an array of titles and icons that i have used for a list view and now i'm wanting to reuse the same arrays to create a layout as displayed here so the layout adds a button for each item in the array and arranges them in 3's according to device width. is this possible to do? I have tried using a custom Array Adapter to generate the Grid but getting a null pointer error at the point menuGrid = (GridView) findViewById(R.id.gridView1); MenuItemsSetup menuData[] = new MenuItemsSetup[] { new MenuItemsSetup(R.drawable.ic_menu_icon1, "menuItem1"), new MenuItemsSetup(R.drawable.ic_menu_icon2, "menuItem2"), new MenuItemsSetup(R.drawable.ic_menu_icon3, "menuItem3"), new MenuItemsSetup(R.drawable.ic_menu_icon4, "menuItem4"), new MenuItemsSetup(R.drawable.ic_menu_icon5, "menuItem5"), new MenuItemsSetup(R.drawable.ic_menu_icon6, "menuItem6"), new MenuItemsSetup(R.drawable.ic_menu_icon7, "menuItem7"), new MenuItemsSetup(R.drawable.ic_menu_icon8, "menuItem8") }; String[] menuBgColours = {"#FFFFFF","#FFFFFF", ,"#888888", "#FFFFBB", "#BBFFFF","#000000", "#666666"}; CustomArrayAdapter adapter = new CustomArrayAdapter(this, R.layout.drawer_list_item, menuData, menuBgColours); menuList.setAdapter(adapter); menuGrid.setAdapter(adapter);

• Rails 3.1 assets not recognizing new images uploaded by rmagick until server restart

  - by Mr_Nizzle

  I have my Rails 3.1.0 application running with passenger in production environment and I have a section where the application allows the user to change his profile picture so I upload the image using an ajax uploader and in my controller I upload the file and generate different sizes for the image with rmagick then I render the new image with an image_tag but the application won't show the image till I restart the server. What I get is No route matches [GET] "assets/path/to/image.png" If I restart the server It will show the image, but obviously I can't be restarting the server every once a user uploads a new image. How can I solve the keeping the assets working the right way?

• Creating get/set method dynamically in javascript

  - by portoalet

  I am trying to create a UserDon object, and trying to generate the get and set methods programmatically ( based on Pro Javascript book by John Resig page 37 ), and am testing this on Firefox 3.5 The problem is: in function UserDon, "this" refers to the window object instead of the UserDon object. So after calling var userdon = new UserDon(...) I got setname and getname methods created on the window object (also setage and getage). How can I fix this? function UserDon( properties ) { for( var i in properties ) { (function(){ this[ "get" + i ] = function() { return properties[i]; }; this[ "set" + i ] = function(val) { properties[i] = val; }; })(); } } var userdon = new UserDon( { name: "Bob", age: 44 });

• Does any one know of a packet generator?

  - by Benoit

  We have a networked device, and we would like to perform some tests on how it handles malformed packets. Is there a product out there that can generate arbitrary packets and packet sequences? I would like to be able to specify a set of TCP/IP payloads and it would open a connection and send the data. Obviouly, the TCP/IP checksum should be calculated correctly, etc... Kind of like a wireshark in reverse. Note that I am not interested in network loading and blasting millions of packet.

• AJAX with Web services and ASP.NET SessionState

  - by needhelp1

  We have an application which uses ScriptManager to generate a client-side proxy which makes AJAX calls to web services. The web services being invoked live in a separate appDomain(separate cluster altogether). The problem is that our application uses a State server for storing session. I want the web services to be able to access session also. First off, does anyone see anything wrong with the client making web service calls to a separate cluster(we're hoping this would be a better approach for scalability)? I was thinking that possibly anytime there is an update to the session dictionary in one appDomain, automatically update the session in the other appDomain also(referring to the web service appDomain, don't know how to do this, only theoretical). What do others think? Thanks!

• Is it possible to bundle a unique file for each copy of iPhone app downloaded from App Store?

  - by futureelite7

  Hi, I would like to verify the identity of each instance of the iPhone application that a user might use to connect to my service. To that end, I would like each instance of the iPhone app downloaded to include a certificate that I generate, or even some sort of UUID that I have generated. Does the App Store support the inclusion of unique files in an app bundle? Or, must such identifiers be downloaded only after the app is installed? If that is the case, is there a mechanism to ensure that the app downloaded is trusted (from me), instead of from an impersonator?
