• Is there a way to make 7zip temporarly uncompress the whole archive when double-clicking on an exe?

  - by Gnoupi

  In WinRAR, one feature which I like is the fact that you can set it to uncompress the whole archive in a temporary place, if you double-click on an .exe file inside the archive opened in WinRAR. Typically, I often download small games, which I just want to try, without the hassle of creating a folder for it, etc. Same for archives containing an installer with its own separate files. In the 7-zip window, if I double-click an exe, it will just extract the exe in a temporary location and launch it. In the small game context (or installer), it means that it will simply fail, because it will miss required files in the same folder. So my question is: Is there a way to make 7-zip extract the whole archive in a temporary folder when launching an exe from inside the archive?

• Thoughts on exception handling.

  - by AndyScott

  Was working on a windows form app (something I haven't done in a while), adding threading and logging so that it would work a little more smoothly and have a record of who did what.  I was just about at the point where I was going to check it into source control when I noticed that the Output window was showing "A first chance exception of type 'System.InvalidCastException' occurred in mscorlib.dll", so I googled it.  In reading some threads about the error, I came across the following comment and it got me thinking: "In addition, while they should be avoided if possible, exceptions are a quite legitimate part of program execution. It's their going unhandled that is a real issue, because that means crashy, crashy." How do you normally use exception handling?  I feel that exceptions are intended to handle errors in code (in my experience generally related to bad data making its way into the system).  Now don't get me wrong, I understand that exceptions happen and should be dealt with, but I feel that they are a "last resort" to keep a program from crashing, but should never be a way to pass data or continue logical processing that could be handled in standard code flow. I mention this, because I have seen it done. What do you think?

• How to revert to Eclipse's old behavior when double-clicking on frames or windows, in Juno?

  - by mattquiros

  I find Eclipse Juno very counter-intuitive. In my workspace, I used to just have the package view at the left, my code on the right, and whenever I'm printing something in the console, that's only when the console frame shows up from the bottom right. When you double click on a particular window, it either only goes fullscreen within Eclipse, or back to its original size together with the size of the other frames. In Juno, however, it seems that frames are put on layers on top of each other. When I print something to the console, the output frame only shows up as a small, useless square to my right. When I double-click, it goes full screen. When I double-click again, it occupies the full right frame, hiding my code. I double-click again and it goes full screen, then it double-clicks before it shares the right frame with my code on top of it. Then when I minimize it, it goes to the side. Any way to go back to the good old days of Eclipse? Thanks.

• How do I tell if my Windows server is swapping?

  - by churnd

  I'm using Process Explorer to monitor my windows server while it reconstructs some data. It's primarily a CPU intensive process, but I want to make sure it's not swapping. How can I tell if it is using Process Explorer? My initial guess is in the System Information window, it's Paging File Write Delta. Yes? No? I'm an idiot? *Screenshot is not of the server... just an example.

• Using VLC to Unicast High Definition Webcam over local gigabit LAN with low/zero delay

  - by Robin Day

  We're setting up a webcam "window" between two offices in the same buildilng. The two PC's are connected to the same gigabit switch. We're using VLC to stream the webcam over HTTP using the following commands. vlc dshow:// :dshow-caching="0" :dshow-size="640x480" :sout=#transcode{vcodec=h264,vb=0,scale=0}:http{mux=ffmpeg{mux=flv},dst=:8080/} :no-sout-rtp-sap :no-sout-standard-sap :ttl=1 :sout-keep vlc http://192.168.0.1:8080 :http-caching="0" Even with the caching set to zero, the delay in the image is a good 2-3 seconds. The CPU usage of each pc is also maxed. I'm guessing it's the transcoding that's causing much of the delay. Can anyone give me some changes to these command lines that will reduce the transcoding power, or send the webcam over a different protocol, or anything that will reduce the delay of the cameras? Bandwidth is not an issue at all as the pc's can be connected to a dedicated switch/vlan if required.

• Force Windows 8 to search indexed files

  - by Hrvoje

  When using search files in Windows 8 (win+f) I don't get expected results. For example, I installed VLC, it's in Program Files (86) folder, and that folder is selected for indexing. Search for files (win+f) gives 0 results. If I pin to start that exe, then it's found - but I don't want to do this, that's not the point. Where does it search for files? Is there any way to specify search locations? It doesn't use Indexing Options settings, at least it seams so. Also, searching from explorer window is kinda slow - I tried entering VLC.EXE in search box (when in c:\ root), and it takes some time to give correct results. It works, but it looks like it doesn't use indexing, rather scan all files/folders, which is slow.

• Netbook Remix 10.04 to 10.10 upgrade using alternate iso

  - by Suman Subramonian

  I'm using Netbook Remix 10.04 now. I'm having the 10.10 alternate iso with me. If I use that iso to upgrade, will I lose my netbook version? I've seen in some forums that the upgrade resulted in a change from netbook version to desktop version. Updated on 15/12/2010 I upgraded the OS from 10.04 to 10.10. But I'm getting an error like this after restart: modprobe: FATAL: Could not load /lib/modules/2.6.35-22-generic/modules.dep: No such file or directory I searched in the forums and got a solution like this: Open Terminal gksudo gedit /etc/initramfs-tools/initramfs.conf change the line MODULES=most to MODULES=dep Then use Synaptic (SystemAdministrationSynaptic Package Manager) to reinstall initramfs-tools. I'll be definitely trying this later. After that when the system tries to login, my screen starts flashing with just the ubuntu netbook desktop wallpaper on the screen. No other options will be available. It will be flashing continuosly. If I press the power button then one window comes up with options like Shut down, Restart, Hibernate etc. And the screen won't stop flashing either. I've uploaded a 1 min video. Please go through it as it will give you a clear idea of the error which I'm facing now Video Link Here

• Windows 7: enabling navigation of subfolders in pinned Start Menu folders

  - by AspNyc

  I'm just about to move from Windows XP to Windows 7, and I'm struggling with some of the interface changes. In XP, I was able to throw a folder intoC:\Documents and Settings\username\Start Menuand have it appear on the Start Menu, complete with the ability to navigate through subfolders. I've figured out how to pin a folder onto the Start Menu in Windows 7, which required a registry hack. However, I am unable to view the subfolders of the pinned folder without opening a new Windows Explorer window. Is there any way to replicate the old XP behavior I'm used to? I'd like to be only a single click away from these handful of application links and folders, since I use them all the time throughout the day.

• BoundingSpheres move when they should not

  - by NDraskovic

  I have a XNA 4.0 project in which I load a file that contains type and coordinates of items I need to draw to the screen. Also I need to check if one particular type (the only movable one) is passing in front or trough other items. This is the code I use to load the configuration: if (ks.IsKeyDown(Microsoft.Xna.Framework.Input.Keys.L)) { this.GraphicsDevice.Clear(Color.CornflowerBlue); Otvaranje.ShowDialog(); try { using (StreamReader sr = new StreamReader(Otvaranje.FileName)) { String linija; while ((linija = sr.ReadLine()) != null) { red = linija.Split(','); model = red[0]; x = red[1]; y = red[2]; z = red[3]; elementi.Add(Convert.ToInt32(model)); podatci.Add(new Vector3(Convert.ToSingle(x), Convert.ToSingle(y), Convert.ToSingle(z))); sfere.Add(new BoundingSphere(new Vector3(Convert.ToSingle(x), Convert.ToSingle(y), Convert.ToSingle(z)), 1f)); } } } catch (Exception ex) { Window.Title = ex.ToString(); } } The "Otvaranje" is an OpenFileDialog object, "elementi" is a List (determines the type of item that would be drawn), podatci is a List (determines the location where the items will be drawn) and sfere is a List. Now I solved the picking algorithm (checking for ray and bounding sphere intersection) and it works fine, but the collision detection does not. I noticed, while using picking, that BoundingSphere's move even though the objects that they correspond to do not. The movable object is drawn to the world1 Matrix, and the static objects are drawn into the world2 Matrix (world1 and world2 have the same values, I just separated them so that the static elements would not move when the movable one does). The problem is that when I move the item I want, all boundingSpheres move accordingly. How can I move only the boundingSphere that corresponds to that particular item, and leave the rest where they are?

• Moving windows using keyboard...faster?

  - by Alois Mahdal

  I like using keyboard shortcuts because it's faster as it does not force me to move my hands off the keyboard. In Windows I can use them to move windows around desktop: Press Alt+Space to open common windows menu Press M to choose "Move" command Navigate window position by cursor keys Confirm new position with Enter Additionally, to achieve better accuracy, I can hold Ctrl while navigating. Now the problem is that the normal "step" when moving is about 20px, and my desktop is quite large, so "walking" all the way across takes quite a long time. This kind of defeats the purpose of using keyboard for these tasks. Is it possible to change size of this step so that takes less steps to walk the same distance? (I imagine a hidden setting in Windows registry...?) I tried holding Alt while navigating, but it does not seem to have influence on speed.

• Navigate to a virtual member from the member that overrides it

  - by axrwkr

  Using visual studio, in the editor window, I am able to navigate from the usage of a member to the line and file where it is declared by pressing F12 while the cursor is over that member by or right clicking on the member and selecting "Go To Definition". I would like to find a way to navigate from an override member to the base class member that it overrides. For example, if I have the following class with one method public class SomeClass { public virtual void TheMethod() { // do something } } An I override that method somewhere else in the project or solution similar to the following public OtherClass : SomeClass { public override void TheMethod() { // do something else } } I want to navigate from the declaration of TheMethod in OtherClass to the declaration of TheMethod in SomeClass Is there a way to do this? I've found that I can find the definition of the member in the base class by pressing Shift + F12 (Find all References) and then looking through the list occurances, this works fine most of the time, since the list isn't usually that long but it would be much better to have a way to go there directly.

• How to disable discrete GPU using NVIDIA drivers?

  - by penzoiders

  I have a DELL studio XPS 13 (aka 1340) as of 12.04 most things run smoothly out of the box, but I have some power draining and warmness issues (if not to be called terrible heat issues) The system came with a NVIDIA GeForce 9500M (which has Hybrid SLI) and it shows up in "lspci" as these 2 cards 02:00.0 VGA compatible controller: NVIDIA Corporation G98 [GeForce 9200M GS] (rev a1) 03:00.0 VGA compatible controller: NVIDIA Corporation C79 [GeForce 9400M G] (rev b1) I had to install nvidia-current over noveau driver 'cause noveau does freeze the system after suspension. By installing nvidia-current and running nvidia-xconfig the resume process after suspension is fixed. By the way both with nvidia-current and noveau the system drains a lot of battery and heats up a lot. I suppose this is because the discrete GPU is always on. I don't really need 3D graphics on this system, if not the minimal to run unity and compiz for window management. So my question is: How do I disable, using nvidia-current, the discrete GPU 9200M and use only the integrated one 9400M? notes: In BIOS I have no option to disable discrete GPU This I think is not applicable because of the suspension-freeze issue (with noveau): https://help.ubuntu.com/community/HybridGraphics I've found this but I don't know which --sli option I should choose to fit my needs: http://manpages.ubuntu.com/manpages/hardy/man1/nvidia-xconfig.1.html My system has not optimus or cuda, but anyone can tell me if bumblebee can work for me?

• Is (Ubuntu) Linux file copying algorithm better than Windows 7?

  - by Sarath

  Windows Copying is a real mess ever since Windows Vista. Even Microsoft claims they've improved the performance, from a user perspective, it's not quite visible. Even with single file the copying window appears too much time for 'Calculating' and then finishing the copy(Even after 100% completion some times the dialog remains active). At the same time, I was backing up some files in Ubuntu Linux. I felt it's really fast. Might be a feeling caused by faster UI updates. I read an informative post from Jeff Atwood few years back on Windows File Copying. but what my specific questions are Is (Ubuntu) Linux file performance is better than Windows-7? Are both algorithms, Windows and Linux is making use of multiple threads and pipelining mechanism to improve the speed? If yes, which one is better?

• Possible to change the order of the shortcut locations in windows explorer

  - by Codezilla

  When you open a new explorer window by default it loads from the starting position "Computer" which shows your drives, etc. This is all well and good except when explorer loads it bumps the scroll bar down so that half the favorites are cut off. I can scroll up to get to the ones I want but that gets really old doing that 50 times a day. I do clean out my favorites frequently but more are added all the time and used. In trying to come up with a fix for this problem I thought maybe it would be possible to move the link to "Computer" to be at the very top and the "Favorites" area directly under that but I can't figure out a way to do that. Anyone have an idea? Or maybe another solution I haven't thought of?

• Google Chrome passphrase : where is it?

  - by danielson

  Every time I do a fresh install, Google Chrome asks me for my passphrase. Have searched high and low in Google's help forum and have yet to receive or find any form of response. When I do a fresh install, if I try to enter the passphrase (with all possible passwords i can recall) nothing works and I can't recover my extensions, bookmarks etc. On the other hand, if I wait a bit, everything falls to place. I close that window asking for passphrase and all my extensions, bookmarks are back. The failure to enter a proper passphrase code gets me a message to change my passphrase in my account settings. Who knows where that is! No one at Google's forum seems to know anything about this "passphrase".

• Game engine lib and editor

  - by luke

  I would like to know the best way/best practice to handle the following situation. Suppose the project you are working on is split in two sub-projects: game engine lib editor gui. Now, you have a method bool Method( const MethodParams &params ) that will be called during game-level initialization. So it is a method belonging to the game engine lib. Now, the parameters of this method, passed as a reference the structure MethodParams can be decided via the editor, in the level design phase. Suppose the structure is the following: enum Enum1 { E1_VAL1, E1_VAL2, }; enum Enum2 { E2_VAL1, E2_VAL2, E2_VAL3, }; struct MethodParams { float value; Enum1 e1; Enum2 e2; // some other member } The editor should present a dialog that will let the user set the MethodParams struct. A text control for the field value. Furthermore, the editor needs to let the user set the fields e1 and e2 using, for example, two combo boxes (a combo box is a window control that has a list of choices). Obviously, every enum should be mapped to a string, so the user can make an informed selection (i have used E1_VAL1 etc.., but normally the enum would be more meaningful). One could even want to map every enum to a string more informative (E1_VAL1 to "Image union algorithm", E1_VAL2 to "Image intersection algorithm" and so on...). The editor will include all the relevant game egine lib files (.h etc...), but this mapping is not automatic and i am confused on how to handle it in a way that, if in future i add E1_VAL3 and E1_VAL4, the code change will be minimal.

• Time tracking similar to Paymo Plus on Debian

  - by aditya menon

  PaymoPlus is free (closed source but no fees) PaymoPlus sits in my System Tray all day, and records every window/tab I open I would like to know if a similar app exists for Debian. Paymo for Windows/Mac has the additional sweet feature of being able to drag and drop working windows/tabs and the time spent into the tasks, but one can live without this. I would at least need to know which tasks got how much time in a 'sum total' calculation so I can enter that time into my Paymo reporting. Any ideas? Paymo does have a desktop widget for Linux but it is a dumb (non-sentient) manual time entry tool, not like Paymo Plus automatically recording everything being done.

• Network print to brother MFC-7420

  - by trampster

  I am trying to pint to a Brother MFC-7420 from my ubuntu 10.04 machine. The brother is attached to a windows XP machine and is shared. This is what I have tried: System-Administration-Printing, Add, Expand Network Printer, Windows Printer via SAMBA, Browse (I can find the printer no problems here), Foward, Choose Driver Dialog, Brother, My printer is not in this list So the next thing I tried was to download the printer driver from here http://welcome.solutions.brother.com/bsc/public_s/id/linux/en/download_prn.html The driver installed fine but my printer still does not appear in the list. I also tried installing the cups wrapper but that gave the following error. Restarting Common Unix Printing System: cupsd [ OK ] cp: cannot stat `/usr/share/cups/model/MFC7420.ppd': No such file or directory dpkg: error processing cupswrappermfc7420 (--install): subprocess installed post-installation script returned error exit status 1 Errors were encountered while processing: cupswrappermfc7420 I tried connecting the printer directly but even though I have installed the driver, when I go to printers and click on the printer (it shows up fine as a USB printer) then it say searching for drivers and then gives me a list, this is the same list as before which doesn't have my printer. It really shouldn't be this hard. on window you don't have to installing anything it just works and the same is true for my brothers Mac. How do I print to my printer?

• SQL Server Authentication vs Windows Authentication

  - by Nandu

  Hi, I am a SQL Server newbie and would really appreciate any help. I have created a new login (test2) with sql server authentication and granted select & vierw definition permission on another schema (test1) to test2. I am however not able to see the objects of test1 in the object explorer. However I can select the objects from the Query Window. Since this new login is being used to develop reports the user would like to view the objects in the Object Explorer. Another user test3 created using windows authentication and similar permissions is able to see test1's objects in the explorer. Please let me if this is the cause and if not how can help test2 see the objects in Object Explorer.

• Facebook Like javascript related to Time Spent Downloading a page Increase in GWT?

  - by donaldthe

  Hi, I installed the Facebook Like button Javascript version on my website on December 15th. Take a look at this report from Google Webmaster Central. Crawl stats Googlebot activity in the last 90 days The crawl stats are from Googlebot which as far as I know doesn't execute Javascript. Could the Facebook Like Javascript code, "The XFBML version" be related to large spike in Time spent downloading a page? (By the way the huge spike in November was caused by a mistake where every image request was getting a 301.) I'm not sure what caused the spike to go down by half somewhere in December. It may have been related to a faulty setting in web.config. I'm at a loss as to what I can do about this or even how to tell if this is my problem or Googlebots crawl problem. Here is the Facebook code I am using to create the like button. It is right after the opening body tag <div id="fb-root"></div> <script> window.fbAsyncInit = function() { FB.init({appId: 'xxxxx', status: true, cookie: true, xfbml: true}); }; (function() { var e = document.createElement('script'); e.async = true; e.src = document.location.protocol + '//connect.facebook.net/en_US/all.js'; document.getElementById('fb-root').appendChild(e); }()); ` and this creates the like box: <fb:like show_faces="false"></fb:like> If the Javascript can't be the problem any ideas on where to start looking would be appreciated.

• Old Fglrx Driver - AMD Radeon HD 3200 - ubuntu won't start

  - by Yohannes

  I've been using Ubuntu 12.04 64 bit for about 2 weeks now and I installed the latest Fglrx driver (Graphics Card- AMD HD 3200, PC- Acer Aspire 5336, 4GB RAM, 500GB Harddrive). The problem is that sometimes video's lag and play out of sync sometimes the windows take long to show up after I've clicked them etc. After looking around I found a video on Youtube by Ubuntu help guy and in the video he recommended using an older driver if you have an older graphics card, his was about 4 years old (same as mine) and he used the 11.10 catalyst driver so I decided to try it. I removed the previous installation of the driver and then installed the 11.10 driver. However, when I restarted it instead of going to the GUI it goes to a terminal like window and asks for my login. Now its pretty clear I need to remove the old driver and go back to using the latest one. The only problem is I'm not sure where I saved the latest driver and in order to connect to the Internet I need to change /etc/resolv.conf (I use a static IP). So what should I do? Also anyone from personal experience, what propitiatory driver works best with my graphics card? As in the version. Thanks

• A software to lock regions of a screen to prevent any windows from overlapping

  - by cybervaldez

  I've just installed nexus dock (a similar application like rocketdock), after playing with the preferences i've come across a very curious option (under position & behavior) that says: Prevent maximized windows from overlapping the dock. With it enabled, any application I maximize(and i do mean any) won't overlap the dock, it's really great. So i'm thinking perhaps there's a software that does this kind of feature which is really ideal for keeping my workspace really organized. I really hate repositioning and resizing my windows everytime. Of course there's always the manual way of doing these but it's just too much of a bother when someone from the family uses the computer. Do you know any software that does this? even a software that can just save/remember window positions would also be nice too.
