• Screenshot of the Nexus One from adb?

  - by Marcus

  My goal is to be able to type a one word command and get a screenshot from a rooted Nexus One attached by USB. So far, I can get the framebuffer which I believe is a 32bit xRGB888 raw image by pulling it like this: adb pull /dev/graphics/fb0 fb0 From there though, I'm having a hard time getting it converted to a png. I'm trying with ffmpeg like this: ffmpeg -vframes 1 -vcodec rawvideo -f rawvideo -pix_fmt rgb8888 -s 480x800 -i fb0 -f image2 -vcodec png image.png That creates a lovely purple image that has parts that vaguely resemble the screen, but it's by no means a clean screenshot.

• implementing ioctl() commands in FreeBSD

  - by thecoffman

  I am adding some code to an existing FreeBSD device driver and I am trying to pass a char* from user space to the driver. I've implemented a custom ioctl() command using the _IOW macro like so: #define TIBLOOMFILTER _IOW(0,253,char*) My call looks something like this: int file_desc = open("/dev/ti0", O_RDWR); ioctl(file_desc, TIBLOOMFILTER, (*filter).getBitArray()); close(file_desc); When I call ioctl() I get: Inappropriate ioctl for device as an error message. Any guess as to what may be doing wrong? I've defined the same macro in my device driver, and added it to the case statement.

• My HttpHandler doesn't want to create directory on a network

  - by Daok

  I use this simple line of code inside my HttpHandler: Directory.CreateDirectory(@"\\srv-001\dev\folderToCreate\"); I receive an UnauthoridezAccessException telling me that the access to the path is denied. From here, I create a little Dos application in C# doing the same thing and I was able to create the folder. So, I thought that it might be that IIS is running on a different user than myself. I went to IIS and changed the Application pool to a Custom user, myself. But, unfortunately, I got the same exception. I have try to create a Share folder on my computer and I can create directory. Also, when debugging I can see that System.Threading.Thread.CurrentPrincipal.Identity have its AuthenticationType to "", IsAuthenticated to false and name to "". So, with all those tests I can conclude that the HttpHandler that receive the file cannot create a directory because of some security access. How can I grand access to my HttpHandler to be able to create a directory (and files) to a network folder?

• Why is the form action attribute empty on production server?

  - by Ozzy

  After deploying a ASP.NET WebForms application to a production server some of the ajax calls has stopped working for me. After some debugging I found out that the following statement (in the internal client-method WebForm_DoCallback) was causing the problem: xmlRequest.open("POST", action, true); The problem seemed to be that the action-variable was empty so after checking the rendered html I found out that the form-tag rendered on the production server looks like: <form method="post" action="" id="Form1"> However, on my developer machine I get the following: <form method="post" action="default.aspx" id="Form1"> So, why would the action-attibute render on my dev.machine but not on the production server? This seems to be the case only for one specific web form, when I look on other pages the action-attribute renders correctly. Any suggestions or ideas would be helpful!

• Cannot Extend Django 1.2.1 Admin Template

  - by jcady

  I am attempting to override/extend the header for the Django admin in version 1.2.1. However when I try to extend the admin template and simply change what I need documented here: http://docs.djangoproject.com/en/dev/ref/contrib/admin/#overriding-vs-replacing-an-admin-template), I run into a recursion problem. I have an index.html file in my project's templates/admin/ directory that starts with {% extends "admin/index.html" %} But it seems that this is referencing the local index file (a.k.a. itself) rather than the default Django copy. I want to extend the default Django template and simply change a few blocks. When I try this file, I get a recursion depth error. How can I extend parts of the admin? Thanks.

• Experiences with "language converters"?

  - by Friedrich

  I have read a few articles mentioning converters from one language to another. I'm a bit more than skeptical about the use of such kind of tools. Does anyone know or have experiences let's say about Visual Basic to Java or vs converters? Just one example to pick http://www.tvobjects.com/products/products.html, claims to be the "world leader" or so in that aspect, However if read this: http://dev.mysql.com/tech-resources/articles/active-grid.html There the author states: "The consensus of MySQL users is that automated conversion tools for MS Access do not work. For example, tools that translate existing Access applications to Java often result in 80% complete solutions where finishing the last 20% of the work takes longer than starting from scratch." Well we know we need 80% of the time to implement the first 80% functionality and another 80% of the time for the other 20 %.... So has anyone tried such tools and found them to be worthwhile?

• Preferred way of using UiBinder with multiple screens

  - by arinte

  We have a GWT app that has multiple screens, based off of a menu. So App loads user sees Do This Do That Each menu item loads a different screen. What is the best way to switch the screens. Right now what I do roughly is RootPanel.get(CONTENT).remove(menu); RootPanel.get(CONTENT).add(new DoThisScreen()); I ask this because it seems on IE 8 (and I am sure 7,6) that the DoThisScreen is basically not recognize by IE's Developer Tool (wannabe firebug tool, when you press F12). Using IE's dev tool I tell it to highlight a textbox in the DoThisScreen, for some reason it won't highlight it or list it in the html.

• X-Domain and P3P Headers

  - by Jackson

  Hi, I have a website A.com and a domain at B.com with a widget inside an iframe getting data from A.com. I want to allow x-domain cookies to be passed from a.com to inside the iframe using ASP.NET My understanding is that - I can do this in IE using P3P Headers - such that the A.com cookie is passed to the iframe and session | cookie data is preserved. The P3P headers have to be sent from the A.com and from the iframe. Is this correct ? In dev, my understanding is if I "accept all cookies" in IE - then P3P headers won't matter anyway and so this should all just work. If I put on Medium Security then P3P is required.

• Managing multiple .NET languages in a web application

  - by tomfanning

  I am part of a development team building a new ASP.NET 3.5 web application. Two of us are C# coders, and the other is a VB.NET coder. I know that we can mix languages on a per-project basis, and one can build classes in one language that inherit from classes written in the other language in a different project (which we are already doing), but I can see us getting into a situation where we might well end up with cyclic dependencies between our various project DLLs. Other than simply having a high number of projects (more seperation of concerns into more libraries), how have you managed this situation on your own projects? Note - I believe this question to be different enough from the only similar match I could find (this one) on the basis that we are not wanting to use different languages in order to take advantage of their specific features per se, but rather to make use of what developer resource is available to us (i.e. one dev just happens to be VB.NET only).

• Web Service URL change is not recognized

  - by ila

  I deployed in a production environment a .net solution that consumes a web service added as "Service reference" in visual studio. Today the endpoint URL has changed, and I modified that URL in web.config. But when I run the solution I get the error: System.ServiceModel.FaultException: Server did not recognize the value of HTTP Header SOAPAction: http://93.62.150.200/LogEvent. Now that sound strange to me. As you can see, the IP is 93.62.... but the new value is different. The web.config entry (with the new value or the URL) is: <client> <endpoint address="http://213.92.50.215/sawfc/WS_SAWFC_Int.asmx" binding="basicHttpBinding" bindingConfiguration="wsSAWFCInterfaceSoap" contract="it.datasphere.ws.wsSAWFCInterfaceSoap" name="wsSAWFCInterfaceSoap" /> </client> I cannot reach the new web service from dev environment, so I cannot modify the Service reference there. Any idea? Thanks a lot!

• Downloading Eclipse's Source Code

  - by digiarnie

  I'm doing a study on large Java projects and would like to view the source code for Eclipse. I have gone to this url (http://wiki.eclipse.org/index.php/CVS_Howto) and figured that the most useful cvs repository for me to look at would be this one: :pserver:[email protected]:/cvsroot/eclipse (The Eclipse platform project) However, when looking at this repository, it has so many modules! Which modules should I be trying to check out? I don't necessarily want to build the IDE from source, however, I just want to get the core Eclipse code base to perform some analysis. Would I just check out any modules starting with "org.eclipse..."? Should I be checking out any of the others? Or is there an easier way to get the source? I read somewhere that you can get the source from the binary version of Eclipse but I am unsure where to find the source.

• GAE API to find where the app is running - local machine OR gae cloud

  - by Jayesh

  Hi, I have a Google App engine application that I want to work differently depending upon if it is running in my local dev environment (i.e. with dev_appserver.py) as against running in actual GAE cloud. Currently I use a flag variable that I manually toggle to achieve that. But I am sure one day I will forget to change it and will lead to problem. So I would like to know if there is an API or some other way to figure out where the GAE app is actually running? Thanks.

• Reviving a deleted file for use in my workspace

  - by John Cowan

  Greetings We run perforce with several users. Each user has their own development website that shows files in their workspace. This is great for making and viewing changes to webpages before submitting them. Sometime ago, we deleted a few pages in Perforce. I would like to revive these pages, but not to make them visible on our live site. I want to view them in my workspace and on my dev site, but I do want to push them out to our live server. In the "depot" tab of my P4 client, I can see the deleted files. I cannot see them in the "Workspace" tab of my client. How can I revive them for use in my Workspace, but not make them live to the world? I'm not a P4 admin so I could use a little guidance. Thanks for any help,

• Using makecert for Development SSL

  - by John

  Here's my situation: I'm trying to create a SSL certificate that will be installed on all developer's machine's, along with two internal servers (everything is non-production). What do I need to do to create a certificate that can be installed in all of these places? Right now I've got something along these lines, using the makecert application in Microsoft Visual Studio 8\SDK\v2.0\Bin: makecert -r -pe -n "CN=MySite.com Dev" -b 01/01/2000 -e 01/01/2033 -eku 1.3.6.1.5.5.7.3.1 -ss Root -sr localMachine -sky exchange -sp "Microsoft RSA SChannel Cryptographic Provider" -sy 12 mycert.cer However, I'm not sure as to how to place this .cer file on the other computers, and when I install it on my local machine IIS, everytime I visit a page via https:, I get the security prompt (even after I've installed the certificate). Has anyone done this before?

• Sending data remotely from iPhone native apps to Rails apps

  - by jpartogi

  Dear all, I have decided to develop a native iPhone apps as a compliment to our webapps. Now I am wondering what are my options to send data remotely from the iPhone apps - since the database is online - to our online database. What I can think of on top of my head - since I come from web dev background - is JSON. My webapps is built using Rails, so I figure it would not be difficult to accept JSON request from the iPhone apps. But the next question is, is it difficult to send JSON data remotely from the iPhone apps? If JSON is not recommendable, what are my other options? Thank you so much for the assistance. Really appreciate it.

• jQuery autocomplete not always working on elements

  - by PoweRoy

  I'm trying to create a greasemonkey script (for Opera) to add autocomplete to input elements found on a webpage but it's not completely working. I first got the autocomplete plugin working: // ==UserScript== // @name autocomplete // @description autocomplete // @include * // ==/UserScript== // Add jQuery var GM_JQ = document.createElement('script'); GM_JQ.src = 'http://jquery.com/src/jquery-latest.js'; GM_JQ.type = 'text/javascript'; document.getElementsByTagName('head')[0].appendChild(GM_JQ); var GM_CSS = document.createElement('link'); GM_CSS.rel = 'stylesheet'; GM_CSS.href = 'http://dev.jquery.com/view/trunk/plugins/autocomplete/jquery.autocomplete.css'; document.getElementsByTagName('head')[0].appendChild(GM_CSS); var GM_JQ_autocomplete = document.createElement('script'); GM_JQ_autocomplete.type = 'text/javascript'; GM_JQ_autocomplete.src = 'http://dev.jquery.com/view/trunk/plugins/autocomplete/jquery.autocomplete.js'; document.getElementsByTagName('head')[0].appendChild(GM_JQ_autocomplete); // Check if jQuery's loaded function GM_wait() { if(typeof window.jQuery == 'undefined') { window.setTimeout(GM_wait,100); } else { $ = window.jQuery; letsJQuery(); } } GM_wait(); function letsJQuery() { $("input[type='text']").each(function(index) { $(this).val("test autocomplete"); }); $("input[type='text']").autocomplete("http://mysite/jquery_autocomplete.php", { dataType: 'jsonp', parse: function(data) { var rows = new Array(); for(var i=0; i<data.length; i++){ rows[i] = { data:data[i], value:data[i], result:data[i] }; } return rows; }, formatItem: function(row, position, length) { return row; }, }); } I see the 'test autocomplete' but using the Opera debugger(firefly) I don't see any communication to my php page. (yes mysite is fictional, but it works here) Trying it on my own page: <body> no autocomplete: <input type="text" name="q1" id="script_1"><br> autocomplete on: <input type="text" name="q2" id="script_2" autocomplete="on"><br> autocomplete off: <input type="text" name="q3" id="script_3" autocomplete="off"><br> autocomplete off: <input type="text" name="q4" id="script_4" autocomplete="off"><br> </body> This works, but when trying on another pages it sometimes won't: e.g. http://spitsnieuws.nl/ works but http://nu.nl and http://dumpert.nl don't work. Trying the autocomplete of jquery ui has more problems: // ==UserScript== // @name autocomplete // @description autocomplete // @include * // ==/UserScript== // Add jQuery var GM_JQ = document.createElement('script'); GM_JQ.src = 'http://ajax.googleapis.com/ajax/libs/jquery/1.4/jquery.min.js'; GM_JQ.type = 'text/javascript'; document.getElementsByTagName('head')[0].appendChild(GM_JQ); var GM_CSS = document.createElement('link'); GM_CSS.rel = 'stylesheet'; GM_CSS.href = 'http://ajax.googleapis.com/ajax/libs/jqueryui/1.8/themes/base/jquery-ui.css'; document.getElementsByTagName('head')[0].appendChild(GM_CSS); var GM_JQ_autocomplete = document.createElement('script'); GM_JQ_autocomplete.type = 'text/javascript'; GM_JQ_autocomplete.src = 'http://ajax.googleapis.com/ajax/libs/jqueryui/1.8/jquery-ui.min.js'; document.getElementsByTagName('head')[0].appendChild(GM_JQ_autocomplete); // Check if jQuery's loaded function GM_wait() { if(typeof window.jQuery == 'undefined') { window.setTimeout(GM_wait,100); } else { $ = window.jQuery; letsJQuery(); } } GM_wait(); // All your GM code must be inside this function function letsJQuery() { $("input[type='text']").each(function(index) { $(this).val("test autocomplete"); }); $("input[type='text']").autocomplete({ source: function(request, response) { $.ajax({ url: "http://mysite/jquery_autocomplete.php", dataType: "jsonp", success: function(data) { response($.map(data, function(item) { return { label: item, value: item } })) } }) } }); } This will work on my html page, http://spitsnieuws.nl and http://dumpert.nl but not on http://nu.nl. (dumpert didn't work on the plugin autocomplete) //http://spitsnieuws.nl <input class="frmtxt ac_input" type="text" id="zktxt" name="query" autocomplete="off"> //http://dumpert.nl <input type="text" name="srchtxt" id="srchtxt"> //http://nu.nl <input id="zoekfield" name="q" type="text" value="Zoek nieuws" onfocus="this.select()" type="text"> Anyone know why the autocomplete functionality doesn't work? Why the request to the php page is not being made? And why I can't add my autocomplete to google.com?

• CFSocketConnectToAddress and unrecognized selector sent to instance

  Hello, I am somewhat new to iPhone dev and I have been getting unrecognized selector when I call CFSocketConnectToAddress in this code. I think it might be something basic that I am doing wrong. Any idea? this is the complete error I get.

• How do I ignore the Perl shebang on Windows with Apache 2?

  - by nbolton

  I have set up a local Perl web environment on my Windows machine. The application I'm working on is originally from a Linux server, and so the shebang for source .pl files look like so: #!/usr/bin/perl This causes the following error on my Windows dev machine: (OS 2)The system cannot find the file specified. Is it possible to change my Apache 2 conf so that the shebang is ignored on my Windows machine? Of course I could set the shebang to #!c:\perl\bin\perl.exe, that much is obvious; but the problem comes to deploying the updated files. Clearly it would be very inconvenient to change this back on each deploy. I am using ActivePerl on Windows 7. Update: I should have mentioned that I need to keep the shebang so that the scripts will work on our shared hosting Linux production server. If I did not have this constraint and I didn't have to use the shebang, the obvious answer would be to just not use it.

• Facebook calling Google App Engine code using GET instead of POST

  - by Nick Gotch

  I've been developing a Facebook app using Google App Engine in Python and the pyfacebook bindings. For weeks everything worked fine but suddenly it stopped. At first I thought it was a code change so I rolled back the entire dev directory to a version I knew worked, but still it failed. It's possible a change I made to the application's settings caused the issue but, if so, I can't figure out what. I've figured out that the problem is that instead of calling the post(self) method of my Main class, Facebook is calling using a GET. Does anyone know why Facebook would use a GET method instead of a POST? It's an IFrame app. Thanks,

• ASP.NET SetAuthCookie weird behaviour

  Hello SO, I'm trying to do user impersonation for a web application we have. The user selects the user they'd like to emulate/impersonate and then clicks the button which fires this: protected void uxImpersonate_Click(object sender, EventArgs e) { ... FormsAuthentication.SetAuthCookie(uxUserToEmulate.SelectedValue, false); Response.Redirect("Impersonation.aspx"); //reload page manually } We have a dev - test - production server environment and on two servers this works just fine, but on another one, in all browsers, it kicks me to the login screen. What's going on and how can I fix it? We're on ASP.NET 2.0

• .NET: Preserving some, but not all query params during redirect

  - by kasper pedersen

  Hi all, Could someone tell me if the code below would achieve what I want, which is: Check if the query parameters 'return_path' and/or 'user_state' are present in the query string, and if so append them to the query string of the redirect URI. As I'm not a .NET dev and don't have a server to test this on, I was hoping someone could give me some feedback. ArrayList vars = new ArrayList(); vars.Add("return_path"); vars.Add("user_state"); string newUrl = "/new/request/uri" + "?"; ArrayList params = new ArrayList(); foreach ( string key in Request.QueryString ) { if (vars.contains(key)) { params.Add(key + "=" + HttpUtility.URLPathEncode(Request.QueryString[key])); } } String[] paramArr = (String[]) params.ToArray( typeof (string) ); String queryString = String.join("&", paramArr); Response.Redirect(newUrl); Thank you :)

• Netbeans Editor Library?

  - by Jeremybub

  Netbeans seems to say in several places that it supports a library to just host the "Netbeans editor" widget in some other program. It has some weird documentation that seems to say a lot, but doesn't really say much about how to use it: http://bits.netbeans.org/dev/javadoc/org-netbeans-modules-editor-lib2/architecture-summary.html I can't seem to find any download for the "Netbeans editor library" (1 or 2), and the documentation they provide says to download the entire mercurial repository, which doesn't really help me, since it doesn't tell me what is part of this "library" and what is not. If someone could point me to a download for this library, or some minimal documentation about how to use it, that would be great. I've already seen the blog post here, but it doesn't really help with getting the library, and it seems to be talking about classes which I can't find in the Netbeans sources I downloaded (Maybe a different version?)

• Using clojure.contrib functions in slime REPL

  - by Tyler

  I want to use the functions in the clojure.contrib.trace namespace in slime at the REPL. How can I get slime to load them automatically? A related question, how can I add a specific namespace into a running repl? On the clojure.contrib API it describes usage like this: (ns my-namespace (:require clojure.contrib.trace)) But adding this to my code results in the file being unable to load with an "Unable to resolve symbol" error for any function from the trace package. I use leiningen 'lein swank' to start the ServerSocket and the project.clj file looks like this (defproject test-project "0.1.0" :description "Connect 4 Agent written in Clojure" :dependencies [[org.clojure/clojure "1.2.0-master-SNAPSHOT"] [org.clojure/clojure-contrib "1.2.0-SNAPSHOT"]] :dev-dependencies [[leiningen/lein-swank "1.2.0-SNAPSHOT"] [swank-clojure "1.2.0"]]) Everything seems up to date, i.e. 'lein deps' doesn't produce any changes. So what's up?

• Coordinating the logging output from a web app installed in a SharePoint farm.

  - by Kelly French

  We are deploying web parts to SharePoint 2007 and would like to include logging (log4net). The ideal solution would be to use a database appender to avoid the problems with knowing which actual server is executing the web part. This questions has been helpful: http://stackoverflow.com/questions/219668/sharepoint-and-log4net. I've got log4net working in a stand-alone web app using Visual Studio dev server using the web.config for the log4net settings and a file appender for the output. I'd like to transition to SharePoint and still use the log file output so I can make sure it's all working first, then change the config around to log to a database. Is this going to be too much trouble? How have other developers added log4.net into their solutions for SharePoint?
