• Laptop charger dying after plugging in?

  - by Corey

  My laptop charger's transformer has a green light on it that indicates that it's plugged in and working. When I plug it into the wall, the light goes on as expected. As soon as I plug it into the laptop, the light immediately turns off and my laptop doesn't get any charge. After that, the charger's light doesn't turn green again, even though it is still plugged into an outlet. I need to unplug it from the wall and wait a few minutes. It's strange - unplugging and immediately re-plugging it does not bring back the charge; I have to wait. Is this a charger issue or a laptop issue? Edit: Hooked the charger into a voltmeter and power went through fine. I guess this means that it's a short in my laptop itself. What are my options now?

• Excel crashes when opening Excel files from Internet Explorer

  - by Rob Z

  I have been running into some issues when opening Excel files from Internet Explorer, generally the first document or two will open fine but after that trying to open a file will cause Excel and Internet Explorer to crash to the desktop without any notifications being given. This doesn't happen for users who are running Excel 2007, but for users with Excel 2003 it may or may not happen to them. The files in question are Excel XML files and Internet Explorer 6 and Excel 2003 are being use. At this time it would not be possible to upgrade Internet Explorer, but it would be able to upgrade to Excel to version 2007 if that would resolve the issue. Overdue Update: We recently upgraded to Firefox at the office which has rendered this error a non-issue; however, it is still unresolved from the standpoint that we haven't been able to come up with an explanation to the issue. Since IE6 is still installed on the systems, a fix to the problem (or explanation of why it's happening) would be appreciated.

• Why can't I 'justify' text that I have copied from PDF into MS Word?

  - by Uday Kanth

  I find it really annoying that when I copy text that looks good in Adobe Reader into Word, the sentences which are left-aligned by default won't change accordingly when I press 'Justify'. The only way I could get the result I need is to press back-spaces and Delete key to align the right border. Why is this? Here's an example from the Word document. The text is right- and center-aligning perfectly but Justify does not seem to work.

• Getting Synergy+ to work with Windows 7 64bit and Windows XP 32bit?

  - by john crisp

  My Windows XP box is Dell 4550 dimension. Windows 7 box is Home Premium. Synergy + installs fine on the Windows 7box, but using Windows xp as the client, it won't work? Do I need to disconnect the vga connection from my monitor and control entirely from the win7 dvi connection? In setting up ( links ) on Windows 7 as the server, I have NO way of inputing info? The setup on the Windows xp box is simple and does so OK, but I can't connect to the Windows xp box! It must be the vga connection on the Windows XP box. In order to use both machines, I have to turn one off and the other on. Hence-the VGA is needed on Windows XP. Any info/help most appreciated.

• How can I print from my lion mac mini to my windows XP, with simple file sharing?

  - by Jules

  I have quite a complicated setup, perhaps. And a lot of history on this issue, I'm hoping that I don't have to buy a new printer. I've got a HP Wireless USB Print Server, which requires client software, I can't just use it as an IP Printer. The HP software is pretty poor on the mac and is no longer supported and often locks up the printer server and takes some considerable effort to actually print something. Let alone if a windows machine attaches to it first. My printer is an Epson Stylus R285. However, the windows client software is fine and we can print from windows 7 / XP without problem. We have simple file sharing setup as this is the only way I could get windows XP to talk to windows 7. However, I can't seem to get my mac mini to connect as anything other than a guest to my xp machine, to connect to the shared printer. I'm not considering some kind of internet printing as this would seems the simplest solution. But I'm not sure what will work with my setup ?

• Lightest Linux Desktop supporting Firefox/graphic browser

  - by Susan Mayer

  I am on Windows and I have a remote server with Ubuntu 10.10. I want to use Firefox or other graphic browser on that remote server. The problem is, the server's memory is only 512MB, so I can install larger desktop environment. I used to use XFCE and NoMachine NX, but they consume too much memory on that Ubuntu server. The only thing I want to use is a graphic browser (for example firefox) on that server. Nothing else. Do you have any good suggestions? Thanks a lot!

• Is it safe to use any USB charger for charging any USB device?

  - by Vineet Menon

  I have an apple USB AC charger which is rated to provide 5V, 1A output and a Sony mp3 player NWZ B143F. I don't know the spec of Sony audio player. But I have another mp3 player from Transcend which is rated to take 5V, 1A input voltage. So, is it safe to assume that Sony or for that matter any mainstream mp3 player would take 5V, 1A as input? Is it safe to use the apple charger with Sony mp3 player?

• How to search with Spotlight more effectively

  - by Chris Adams

  I'm used to using various flags to modify the results of Google searches, to only show results from a particular site, or only certain kinds of files. For example you can restrict Spotlight searches to only look for pdf files like this example, when I'm looking for a pdf cheatsheet for using YUI's grid system css framework on my computer. YUI grid kind:pdf I'd be amazed if Apple's Spotlight didn't have loads of other handy flags to fine tune a search in the same way - what tricks do you use, or where do you look to find more tips to improve your Spotlight-fu?

• DIrect videos and slideshows fullscreen from another display

  - by neurino

  I have 3 displays: 1 control display I can see 2 40" Full HD displays I can't see my need is to play videos and presentations fullscreen on the two 40" screens while being able to control them from the control display. So far I am able to achieve this with a cumbersome set of keyboard shortcuts like: open VLC on control display send to left display with Win + Shift + Left go fullscreen with f and more combinations to restore, get VLC on control display etc. This is really error prone and not professional. Also I wish I have a media player and a slideshow player that can: send the same video / slideshow to the two 40" displays at the same time send two different videos / slideshows, one each 40" display having all controls on the central display, the only one I can see. Any advice welcome, thank you for your support.

• How can I prototype my app better?

  - by uber_llama

  A few weeks ago I saw a story about a master app designer showing how he worked with good old pen and paper to do effective prototyping before writing code. I'm unable to dig up that story (and I think it was a video) but if you could recommend any other useful resources I'd appreciate them. I know roughly what I want to build, but want a useful framework for thinking about how the screens should flow together. The app I want to build is for the iOS platform, but I think the video might have been about creating a web app. Thanks!

• How to properly structure a project in winform?

  - by user850010

  A while ago I started to create a winform application and at that time it was small and I did not give any thought of how to structure the project. Since then I added additional features as I needed and the project folder is getting bigger and bigger and now I think it is time to structure the project in some way, but I am not sure what is the proper way, so I have few questions. How to properly restructure the project folder? At the moment I am thinking of something like this: Create Folder for Forms Create Folder for Utility classes Create Folder for Classes that contain only data What is the naming convention when adding classes? Should I also rename classes so that their functionality can be identified by just looking at their name? For example renaming all forms classes, so that their name ends with Form. Or is this not necessary if special folders for them are created? What to do, so that not all the code for main form ends up in Form1.cs Another problem I encountered is that as the main form is getting more massive with each feature I add, the code file (Form1.cs) is getting really big. I have for example a TabControl and each tab has bunch of controls and all the code ended up in Form1.cs. How to avoid this? Also, Do you know any articles or books that deal with these problems?

• Was API hooking done as needed for Stuxnet to work? I don't think so

  - by The Kaykay

  Caveat: I am a political science student and I have tried my level best to understand the technicalities; if I still sound naive please overlook that. In the Symantec report on Stuxnet, the authors say that once the worm infects the 32-bit Windows computer which has a WINCC setup on it, Stuxnet does many things and that it specifically hooks the function CreateFileA(). This function is the route which the worm uses to actually infect the .s7p project files that are used to program the PLCs. ie when the PLC programmer opens a file with .s7p the control transfers to the hooked function CreateFileA_hook() instead of CreateFileA(). Once Stuxnet gains the control it covertly inserts code blocks into the PLC without the programmers knowledge and hides it from his view. However, it should be noted that there is also one more function called CreateFileW() which does the same task as CreateFileA() but both work on different character sets. CreateFileA works with ASCII character set and CreateFileW works with wide characters or Unicode character set. Farsi (the language of the Iranians) is a language that needs unicode character set and not ASCII Characters. I'm assuming that the developers of any famous commercial software (for ex. WinCC) that will be sold in many countries will take 'Localization' and/or 'Internationalization' into consideration while it is being developed in order to make the product fail-safe ie. the software developers would use UNICODE while compiling their code and not just 'ASCII'. Thus, I think that CreateFileW() would have been invoked on a WINCC system in Iran instead of CreateFileA(). Do you agree? My question is: If Stuxnet has hooked only the function CreateFileA() then based on the above assumption there is a significant chance that it did not work at all? I think my doubt will get clarified if: my assumption is proved wrong, or the Symantec report is proved incorrect. Please help me clarify this doubt. Note: I had posted this question on the general stackexchange website and did not get appropriate responses that I was looking for so I'm posting it here.

• Java(standard, non standard) or Non Java based Web developement [closed]

  - by LivingThing

  I am new to web development. Initially i thought i would be learning LAMP or WAMP to acquire web developement skills but recently i came across Standard Java based (JSP, servlets) and Non standard Java based (GWT). My question is related to if and how LAMP can be compared with Java (standarad or non stadard) technologies. Is LAMP even comparable to Java based tech or it does something else or something more or less ? what requirement for a web developement projects require the choice that which of these 'technologies' should be choosen ?

• Designing complex query builders in java/jpa/hibernate

  - by Ramraj Edagutti

  I need to build complex sql queries programatically, based on large filter conditions. For example, below are few sample/hypothitical filter conditions, based on which i need to fetch users Country: india States: Andhra Pradesh(AP), Gujarat(GUJ), karnataka(KTK) Districts: All districts in AP except 3 district, 5 any districts from GUJ, all district from KTK except 1 district Cities: All cities in AP, all cities except few, include only 50 specific cities from KTK Villages: similar conditions like above with varies combinations... Currently, we have a query builder, which is very complex in nature, and not easy to modify/re-factory for improvements. So, thinking of complete re-design of it. Any suggesations on how to build this kind of complex query builders programmatically using some best practices/deisgn patterns?

• Which architecture should I choose for this project?

  - by Jichao

  I have a project. The server which based on a phone PCI-board is responsible for received phone calls from the customer and then redirect the phone calls to the operators. I have decided to code the server using c++ programming language and qt framework because the PCI-board SDK's interface is c/c++ originated and for the sake of portability. The server need to send the information of the the customer to the operator while ringing the operator and the ui interface of the operator client should be browser-based. Now the key problem is how could the server notify the operator that there is a phone call for he/she. One architecture I have considered is like this, The operator browser client use ajax pooling the web server to check whether there is call to the client; the web server pooling the database server to check whether there is call; the desktop server(c++) wait for the phone calls and set the information in the database. The other operations such as hang up the phone call from the client, retransfer the phone call to the other operator also use this architecture. Then, is there any way other than pooling the server(js code setInterval('getDail', 1000)) to decide whether there is a call to the operator? Is this architecture feasible or should I use some terrific techniques that I do know such as web services,xml-rpc, soap???

• Are there advantages to using a DVCS for a solo developer?

  - by SnOrfus

  Right now, I use visual svn on my server, and have ankhsvn/tortoise on my personal machine. It works fine enough, and I don't have to change, but if I can see some benefits of using a DVCS, then I might give it a go. However, if there's no point or difference using it without other people, then I won't bother. So again, I ask, are there any benefits to using a DVCS when you're the only developer?

• Audio comes out of both headphone and speaker at the same time.. Ubuntu 12.04LTS [closed]

  - by pst007x

  I have the same issue on an Aspire. Ubuntu 12.04LTS 64bit realtek audio sound chip onboard If I plug in a headset, audio does not switch from internal speaker to headset, instead plays out of both at the same time. I have looked at the alsamixer setting, all on. I installed gnome-alsamixer, and I noticed headphone was ticked, if I untick the main audio mutes, and the headphone no longer works.

• RabbitVCS displaying unchanged files on commit

  - by misterjinx

  I have a strange problem with RabbitVCS. I'm inside a working copy directory and I want to commit some files. When I click the commit button, the commit window shows up, but there is a strange situation. Even though I have modified just a few files, the commit window is displaying all the files and directories inside working copy and the checkbox is ticked for each of them, like those files need to be committed. But those files were not changed and already exist in the repo. Please see the image below to understand what I'm saying (the only file that is unversioned/was changed is .htaccess, therefore it should have been the only file listed there). Has this happened to anyone ? It is a bug with RabbitVCS (and probably a solution exists) or am I doing something wrong ?

For example user A got mapped to home folder of user B User B got mapped to home folder of user C User C got mapped to home folder of user A How do I change this so that the users get mapped to their correct account.
