• repair window-xp - access denied for "document and settings" through command line

  - by Or A

  hi, i'm trying to repair my windows xp and it fails to reboot (bad sector or something). i'm using my dell recovery disk and then select the "Repair" option which takes me to the command line application when i can browse my files and folders (like with cmd.exe). however, when i'm trying to access the "Documents and settings" folder, it gives me access denied. is there any way to override it? is there any other way to access my documents and settings through other method? I'm just trying to recover some files and copy them to another drive on my computer and then reinstall my winxp. Thanks for the help

• Restore open applications, documents, and window state

  - by rfeague

  When working on a project, I generally have a couple of Explorer windows open to relevant folders and a couple of applications (e.g. Eclipse and a form development tool) open to specific project-related documents. There's a lot of value in that context, and I'd like to find a way to save a set of open apps under a project name, then restore that state at a later date. Thus far all of the utilities I've found are virtual desktop products that don't save/restore state. I'm specifically looking for something that will run the applications I had running, open the documents I had open, and position the windows as they were. I'm amazed that such a seemingly simple concept as "Save my workspace state" doesn't seem to be available. I'm on Windows 7. Any suggestions?

• ubuntu 10.04 span window across workspaces

  - by jakerman999

  I'm using an old server machine as a linux box desktop, and as such I have a lot of power but not a lot of display options. I cannot increase my resolution past 800x600 and recently this has become just to small. I have mostly been able to workaround windows being to large for a workspace by moving them with the alt key, but I would like to use something a little more versatile. My plan is to have a setup where I can open a windows (say firefox) on the top-left workspace and then resize it so that it fills four workspaces in an emulated "wall of monitors" fashion. I already have my workspaces arranged like this, but I am not seeing any options for allowing programs/windows to exist on more than one workspace at a time, I know that what I am trying to accomplish is possible (or was at some point in time) because when I google my solution pages appear with people trying to do the opposite (windows already appear on more than one workspace and they dislike it). Any help is much appreciated.

• Create taskbar shortcut to website in Window 7

  - by BJ292

  I'd like to create a shortcut to a website in Windows 7 on the taskbar that is not pinned to the default web browser. Currently if I drag the favicon from the left end of the firefox address bar to the Win 7 taskbar it will pin a shortcut to the firefox browser icon. Similarly if I create a shortcut on the desktop to a website and drag it to the taskbar it will also end up pinned to the firefox icon. The problem with this is to get to that shortcut I have to right click on the firefox icon and then select the pinned shortcut. That is workable for me but I want to do this for a child - so the shortcut needs to be right there on the taskbar as a stand-alone item. There is a workaround that pretty much solves the problem - create a new folder somewhere safe - create the shortcut to the website in the new folder - right click the taskbar and select toolbars - new toolbar - then browse to the folder you created and select it as the new toolbar. The contents of the folder will now appear on the taskbar as shortcuts. You need to drag it from the right hand end of the taskbar into the middle - turn off show titles and show text and make the icon large. I'd call this a 75% solution. Anyone know how to make a web shortcut that looks and operates just like any of the other shortcuts on the taskbar?

• Is there a Windows equivalent for eventfd?

  - by Leaurus

  I am writing a cross-platform library which emulates sockets behaviour, having additional functionality in the between (App-mylib-sockets). I want it to be the most transparent possible for the programmer, so primitives like select and poll must work with accordingly with this lib. The problem is when data becomes available (for instance) in the real socket, it will have to go through a lot of processing, so if select points to the real socket fd, app will be blocked a lot of time. I want the select/poll to unblock only when data is ready to be consumed (after my lib has done all the processing). So I came across this eventfd which allows me to do exactly what I want, i.e. to manipule select/poll behaviour on a given fd. Since I am much more familiarized with Linux environment, I don't know what is the windows equivalent of eventfd. Tried to search but got no luck. Anyone can help me, please?

• 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.

• Get seconds since epoch in any POSIX compliant shell

  - by mattbh

  I'd like to know if there's a way to get the number of seconds since the UNIX epoch in any POSIX compliant shell, without resorting to non-POSIX languages like perl, or using non-POSIX extensions like GNU awk's strftime function. Here are some solutions I've already ruled out... date +%s // Doesn't work on Solaris I've seen some shell scripts suggested before, which parse the output of date then derive seconds from the formatted gregorian calendar date, but they don't seem to take details like leap seconds into account. GNU awk has the strftime function, but this isn't available in standard awk. I could write a small C program which calls the time function, but the binary would be specific to a particular architecture. Is there a cross platform way to do this using only POSIX compliant tools? I'm tempted to give up and accept a dependency on perl, which is at least widely deployed. perl -e 'print time' // Cheating (non-POSIX), but should work on most platforms

• Add/remove xml tags using a bash script.

  - by sixtyfootersdude

  I have an xml file that I want to configure using a bash script. For example if I had this xml: <a> <b> <bb> <yyy> Bla </yyy> </bb> </b> <c> <cc> Something </cc> </c> <d> bla </d> </a> (confidential info removed) I would like to write a bash script that will remove section <b> (or comment it) but keep the rest of the xml intact. I am pretty new the the whole scripting thing. I was wondering if anyone could give me a hint as to what I should look into. I was thinking that sed could be used except sed is a line editor. I think it would be easy to remove the <b> tags however I am unsure if sed would be able to remove all the text between the <b> tags. I will also need to write a script to add back the deleted section.

• Processing a log to fix a malformed IP address ?.?.?.x

  - by skymook

  I would like to replace the first character 'x' with the number '7' on every line of a log file using a shell script. Example of the log file: 216.129.119.x [01/Mar/2010:00:25:20 +0100] "GET /etc/.... 74.131.77.x [01/Mar/2010:00:25:37 +0100] "GET /etc/.... 222.168.17.x [01/Mar/2010:00:27:10 +0100] "GET /etc/.... My humble beginnings... #!/bin/bash echo Starting script... cd /Users/me/logs/ gzip -d /Users/me/logs/access.log.gz echo Files unzipped... echo I'm totally lost here to process the log file and save it back to hd... exit 0 Why is the log file IP malformed like this? My web provider (1and1) has decide not to store IP address, so they have replaced the last number with the character 'x'. They told me it was a new requirement by 'law'. I personally think that is bs, but that would take us off topic. I want to process these log files with AWstats, so I need an IP address that is not malformed. I want to replace the x with a 7, like so: 216.129.119.7 [01/Mar/2010:00:25:20 +0100] "GET /etc/.... 74.131.77.7 [01/Mar/2010:00:25:37 +0100] "GET /etc/.... 222.168.17.7 [01/Mar/2010:00:27:10 +0100] "GET /etc/.... Not perfect I know, but least I can process the files, and I can still gain a lot of useful information like country, number of visitors, etc. The log files are 200MB each, so I thought that a shell script is the way to go because I can do that rapidly on my Macbook Pro locally. Unfortunately, I know very little about shell scripting, and my javascript skills are not going to cut it this time. I appreciate your help.

• best way to authenticate and consume web service using phonegap (html5/javascript)

  - by Raiss

  I am going to develop a phonegap application which is pretty simple. I need to implement an authentication and some simple data transfer back and forth to the phone and server. I prefer to use ASP.NET as a web service and our database is MS SQL but I am not sure what approach should I take to create a secure communication between Phonegap App and webservice. The problem with a simple AJAX request is limitation in cross-domain and I’m not sure if JSONP is a good option. I was wondering if someone can tell me what technology I should use in order to make a semi secure connection which works with PhoneGap (html5, javascript ) and .Net webservice. I understand that it’s a general question but I need to know what technology is the best in such a case. thanks

• Changing Render Kits in Browser

  - by John

  I'm working on a project to develop a cross-browser testing web app. Simply put, I'm tired of having to maintain multiple browsers on the same system and IE in VMware solely for the purpose of testing. Does anyone know if there is any way to change the render kit programmatically? For example, if I insert a URL, I would be able to load the URL and switch the browser render within a frame of some assortment. I am experienced with PHP, JS, and RoR if there is a solution using any of those. Thank you! John

• How to split a path platform independent?

  - by Janusz

  I'm using the following code to get an array with all sub directories from a given path. String[] subDirs = path.split(File.separator); I need the array to check if certain folders are at the right place in this path. This looked like a good solution until findBugs complains that File.separator is used as a regular expression. It seems that passing the windows file separator to a function that is building a regex from it is a bad idea because the backslash being an escape character. How can I split the path in a cross platform way without using File.separator? Or is code like this okay? String[] subDirs = path.split("/");

• silverlight for .NET / CLR based numerical computing on osx

  - by Jonathan Shore

  I'm interested in using F# for numerical work, but my platforms are not windows based. Mono still has a significant performance penalty for programs that generate a significant amount of short-lived objects (as would be typical for functional languages). Silverlight is available on OSX. I had seen some reference indicating that assemblies compiled in the usual way could not be referenced, but not clear on the details. I'm not interested in UIs, but wondering whether could use the VM bundled with silverlight effectively for execution? I would want to be able to reference a large library of numerical models I already have in java (cross-compiled via IKVM to .NET assemblies) and a new codebase written in F#. My hope would be that the silverlight VM on OSX has good performance and can reference external assemblies and native libraries. Is this doable?

• Game Programming - GUIs

  - by Spencer

  I've been coding for a while now and would like to start looking into programming games. I know the industry's standard language is C++, for 3D graphics the main choice is between Direct 3D and OpenGL, but what is the most widely used GUI framework? I'm currently on a Mac so if native Windows API is the answer, then what is the cross platform choice? To be clear, I'm not looking for people's favourites but simply what the common or standard game industry's choice is so that I can learn and familiarize myself with it. Thanks, Spencer

• Detecting a image 404 in javascript.

  - by xal

  After a user uploads a file we have to do some additional processing with the images such as resizing and upload to S3. This can take up to 10 extra seconds. Obviously we do this in a background. However, we want to show the user the result page immediately and simply show spinners in place until the images arrive in their permanent home on s3. I'm looking for a way to detect that a certain image failed to load correctly (404) in a cross browser way. If that happens, we want to use JS to show a spinner in it's place and reload the image every few seconds until it can be successfully loaded from s3.

• Make two servers talk to each other

  - by Maksim

  I have application written in GWT and hosted on Google AppEngine/Java. In this application user will have an option to upload video/audio/text file to the server. Those files could be big, up to 1gb or so and because GAE/J does not support large file I have to use another server to store those files. This would be easy to implement if there was no cross-domain security feature in browsers. So, what I'm thinking is to make GAE Server talk to my server (Glassfish or any other java servers if needed) to tell url to the file and if possible send status of uploaded file (how many percent was uploaded) so I can show status on clients screen. Here is what I'm thinking to do. When user loads GWT page that is stored on GAE/J he/she will upload file to my server, then my server will send response back to GAE and GAE will send response to the client. If this scenario is possible what would be the best way to implement GAE to Glassfish conversation?

• How can I detect if the browser has encountered a JavaScript error ... in JavaScript?

  - by RichH

  For automated testing reasons I want to detect if the browser has encountered JavaScript errors for a page. The type of things that would cause the red numbers in the bottom right in Firebug or yellow warning icon in the Internet Explorer status bar. These JS errors could come from any one of a large numbers of scripts. How in JavaScript can I detect these browser errors? Cross browser solutions prefered, but hey, I'll take anything! As a bonus it would also be great to know the script that caused the error.

• I write barely functional scripts that tend to not be resuable and make the baby jesus cry. Please h

  - by maxxpower

  I received a request to add around 100 users to a linux box the users are already in ldap so I can't just use newusers and point it at a text file. Another admin is taking care of the ldap piece so all I have to do is create all the home directories and chown them to the correct user once he adds the users to the box. creating the directories isn't a problem, but I'd like a more elegant script for chowning them to the correct user. what I have currently basically looks like chown -R testuser1 testgroup1 /home/tetsuser1; chown -R testuser2 testgroup2 /home/testgroup2; chown -R testsuser3 testgroup1 /home/testuser3 bascially I took the request that the user name and group name popped it into excel added a column of "chown -R" to the front, then added a column of "/", copied and pasted the username column after it and then added a column of ";" and dragged it down to the second to last row. Popped it into notepad ran some quick find and replaces and in less than a minute I have a completed request and a sad empty feeling. I know this was a really ghetto method and I'm trying to get away from using excel to avoid learning new scripting techniques so here's my real question. tl;dr I made 100 home directories and chowned them to the correct users, but it was ugly. Actual question below. You have a file named idlist that looks like this (only with say 1000 users and real usernames and groups) testuser1 testgroup1 testuser2 testgroup2 testuser3 testgroup1 write a script that creates home directories for all the users and chowns the created directories to the correct user and group. To make the directories I used the following(feel free to flame/correct me on this as well. ) var= 'cut -f1 -d" " idlist' (I used backticks not apostrophes around the cut command) mkdir $var

• AJAX vs ActiveX/Flash for browser-based game

  - by iconiK

  I have been following the usage of JavaScript for the past few years, and with the release of extremely fast scripting engines (V8, SquirrelFish Extrene, TraceMonkey, etc.) the possibilities of JavaScript have increased dramatically. However, the usage share of Internet Explorer coupled with it's total lack of support for recent standards makes me want to drop a bomb on Microsoft's HQ, as it creates a huge amount of problems for any website. The game will need to be pretty dynamic client-side, with animations and other eye-candy things, but not a full-blown game like those that run directly in the OS using DirectX or OpenGL. However, this might be a little stretch for JavaScript and will certainly feel extremely slow in Internet Explorer (given that the current IE engine can be hundreds of times slower than SFX; gotta see what IE9 will bring), would it be better to just do the whole thing in Flash? I know this means requiring the plug-in AND I have no experience whatsoever with Flash (other than browsing YouTube :P). It also means I can't just output directly from PHP, I would have to use XML or some other format to pass data to it (JSON is directly integrated in JS and PHP can deal with it easily). Another idea would be to provide an alternative interface just for IE, though I don't know how (ActiveX maybe? or with Flash, then why not just provide it to all browsers) or totally not supporting it and requiring the use of other browsers, although this is plain stupid from a business perspective. So here am I, wondering what approach to take and thus asking for your advice. How should I build the client-side? AJAX in all browsers, Flash in all browsers or a mix (AJAX for "modern" browsers and something else for the "grandpa": IE).

• EasyXDM passing data issue

  - by Jeff Ryan

  I'm using rpc with XDM, and I can send simple data back and forth easily between child and parent window. But it seems to be limited to simple strings and numbers. The demos on the site only use numbers. When I try to send a json ecoded string, I get a cross domain error. When I use cors, I can make ajax requests fine, but I can't display the child page in the iframe, because the data is returned and not rendered. My question is, how can I render an iframe, and pass complex data back and forth. Or maybe I am doing something wrong?

• restrict script inside iframe to run only within pages of same top-level domain?

  - by Justin Grant

  I'd like to enforce a requirement that client script inside a page (which in turn is loaded inside an iframe of another page) will only run when the parent page is on the same top-level domain as the framed page (although it may be on another hostname in that domain). Is this do-able? I assume that the easy solution of looking at top.location.host won't be available due to cross-site scripting limitations, but I'm wondering if other javascript hackery could suffice. Constraints on any potential solution inculde: I need to be able to run XmlHttpRequest calls inside the child page, and I need to validate that the hostname is in the same domain before I make those calls. (this makes a document.domain solution challenging because AFAIK setting document.domain disables the ability to make XmlHttpRequest calls. I can control client-side script and HTML on both parent or child (and I can create new pages if needed), but I can't make any server-side code changes. I can't simulate the above via server-side calls or proxies, because the child page's hostname uses a forms auth system with hostname-scoped cookies that I can't get access to from the parent page since it's on a different hostname. I don't have enough control over the child-frame site to be able to put both sites behind the same reverse-proxy or load-balancer (which would enable me to put both sites on the same hostname). I don't actually need to access any UI inside the IFrame-- the iframe is invisible and I'm only using it to run javascript within the security context of a site on a different hostname from the parent page. So at this point I'm stumped. Got any ideas? I want to make sure I'm not overlooking an easy solution before giving up.
