• How can I remove LibUSB on Windows 7?

  - by Cokegod

  I've installed LibUSB, a software that modifies your USB driver so that programs can access it easily. I didn't know that in Windows 7 you have to run it in compatibility mode for Windows XP, so now my Windows 7 can't access any USB port (including keyboard and mouse). Now I can't access my computer at all, and I don't have any PS2 connection in my computer. I tried to run it in Safe Mode but it didn't change anything. I tried to run a system restore from before the installation of LibUSB, but all the restore points give me an error: "The instruction at 0x73888f18 referenced memory at 0x00000004. The memory could not be read." I also tried to run Hiren's Boot CD and remove all the files associated with LibUSB, but that didn't change anything. So how can I remove LibUSB and access my computer again without formatting my hard drive? (I have important things on it)

• Why doesn't Spotlight find Applications on OS X Server?

  - by Clinton Blackmore

  On our Mac OS X Server 10.5.x boxes, using spotlight (ie. the magnifying glass in the top corner) does not find applications and utilities, but it does on Mac OS X client (and so, we all use the keyboard shortcut and end up frustrated -- it either gives us nothing, or, without us realizing it until later, an application from another partition.) It isn't clear to me if we've done something strange setting up our servers, but they are all like this. Any idea what caused it and how we fix it? Everything (including Applications) are set to show up in a spotlight search in System Preferences).

• Computer Locks Up Completely When Resuming From Standby

  - by kcoppock

  Okay, so I'm having a strange issue lately with my desktop, and off the top of my head I'm not sure what the problem is, so I'm hoping for some ideas on how to track down the cause. First, my PC: AMD Phenom 9600 Quad-Core 2.4 GHz 4 GB DDR2 160 GB boot HDD 1 TB & 120 GB secondary HDD Nvidia GeForce 8600 GTS Windows 7 Professional 64-bit I have my power settings as follows: Turn off the display: 10 minutes Turn off hard disk: 20 minutes Sleep after: Never After a while, I'll come back to use my computer again, wiggle the mouse, and the screen comes back on like normal, but the desktop is unresponsive. I can move the cursor, but nothing responds to clicks or keyboard entry. If I click a few times with the mouse, the computer eventually locks up completely and the mouse cursor stops moving as well. After I restart, everything works just fine. Is there a log you recommend checking or really any suggestions would be welcome at this point. Thanks!

• Is it a good idea to work on header files only, just at the start of the project?

  - by m4design

  To explain my point further, I'm a beginner in programming, and I'm working on a small project. Instead of separating the .cpp file from the header file, I'm implementing the code in the header files, and making one .cpp file for testing. I do this to have less files, hence easier navigation. Then later I'll separate the code as it should be. Will this cause any problems? should I continue doing that? Thanks.

• Gnome 3 screensaver (not suspend) resume hook?

  - by Daniel

  Since whenever my laptop screen resumes sleeping (i.e. wakes up from screensaving) some settings are reset, such as keyboard backlight, I'd like to run some scripts each time this happens. I'm using gnome 3 with fedora 17 by the way. When researching this issue I came across pm-utils which allows one to hook anything to events handled by pm-utils but it seems to me monitor sleeping (i.e. screensaving) is not one of them. Looks like pm-utils only handles suspend and hybernate. So is there a way to hook up custom programs to screensaver?

• OSX Lion - Stuck in Drag mode and mouse click events are not going through. Can I manually generate a mouseup event?

  - by Yuji Tomita

  My mouse is stuck in "drag" mode. This generally happens in Photoshop, but happens dragging files and such as well. Clicking rapidly here and there generally solves the problem. Sometimes though, it won't go away until a restart. Unplugging devices, etc., doesn't do anything. For example, right now, my mouse moves but can not click anything so I am using the keyboard to navigate this site. Is there a way to "reset" however the OS stores mouse states? Can I manually fire off a MouseUp event? It's strange that even when human input devices are unplugged, the files are still in drag state.

• Did anyone see the spasticNav.js Menu for jQuery ?

  - by Ricky

  Helooo all, If anyone doesn't know what i'm talking about, this is the link: http://net.tutsplus.com/tutorials/html-css-techniques/how-to-build-a-lava-lamp-style-navigation-menu/ How can i click the menu, and make it “stick” :) without reloading the whole page ? The plugin takes a static state of the tag UL – and run the plugin on it. which mean that if i move the “currentPageItem” from the first LI tag and give it to the next LI tag – the spasticNav doesn’t run for each object again. it still “remembers” the old state. ( because the .js file run only once at the top of the page ) So what should I add to the code in order to get dynamic “Click” event ? ( without reloading the whole page [ ajax ] ) Does anyone have any ideas about this specific plugin ? Thanks.

• iphone sdk: Table view not working in the first 5 tabs but in the more view

  - by LHT

  Hi, I only started with sdk but this problem is bugging me now for a view days: I created a UITableView and added it to my Tabs. When this TableView is in the first 4 Tabs and u go look at it, it only shows the items on the table but when clicking on them nothing happens (it doesn't go to the next view). BUT when i put this same tab behind the 5th so it goes in the automatic MORE view everything works fine. I'm assuming this is because this more view is implementing some kind of table class. But i can't figure it out. I compared all the files with a working example but it seems to be all the same. ah ya my current project is a window based application. Though i copied most of the code from a navigation based application. Any ideas?

• Remote desktop solution for controlling a remote OS X machine in Linux

  - by synic

  The "server" (the host I'm trying to connect to) is Snow Leopard. The "client" is Ubuntu 10.04. I want something like a remote desktop server running on OS X that I can connect to and control from the Linux machine. Something cheap or free would be best. Something that always runs on the OS X machine so that I never have to attach a monitor or a keyboard. I don't want to use VNC, because, well, VNC sucks over this network. Any ideas?

• Dell D630 - Touchpad does not move the mouse cursor

  - by Dean McKenzie

  Windows XP - Dell D630 - Synaptics Touch Pad driver installed. The system tray icon that shows the movement of your finger on the touchpad registeres movement. The scroll feature of the touchpad works on any window with a scroll bar. The double click works even. But it never actually moves the cursor on the screen. An external mouse works with out problems, and I've replaced the palm-rest/touchpad and it continues to happen. The touch stick in the middle of the keyboard works without problems. Does anyone have any ideas?

• How do I start silverlight on netflix in full screen automatically?

  - by KronoS

  I know that there this great big button that I can click for full screen on the bottom left of the screen. What I'm doing though is launching the direct movie/tv episode in chrome from XBMC using XBMCflicks. It's like pasting the video html address in the address bar and going directly to the video feed. Here's my dilemma, I want a fully working, no need for a keyboard/mouse HTPC, which means I don't want to have to click on the 'full screen' button. Is there a way to run chrome and silverlight automatically in full screen mode when launched?

• JQuery Selector - Select this, not that?

  - by JasonS

  Hi, I have created a script which is surprisingly working. (I do not do much JavaScript) What I have is a load of images listed within a div. These images are hidden. JQuery gets the properties of the images and puts them into an array. When the body is clicked, the background image of the page changes. This works nicely. However, I now have a problem. There are several elements which I shouldn't change the background when they are clicked. Namely, navigation, footer and caption. How do I create a selector which makes the body clickable, yet ignores clicks on the above 3 div's?

• Flex 4.5 - to long build process

  - by Idob

  We are developing an app using flex 4.5. The app runs just fine (no performance issues at all) but it takes us forever to compile and build it. A minor change, like just add a comment or press enter in an mxml file and rebuild takes about 3 minutes. You just cant work that way. It is a large project with about 1300 files. We also use Parsley as IOC container and a beat of cairngorm navigation. We also use Maven (Flex mojos) but I am talking about a normal eclipse build (Ctrl + B). We separated some of the code to a different SWC and all of our graphics are stored in a different resource SWF. Please, Do you have any suggestions? Regards, Ido

• Problems with Black Box KVM

  - by MrWizard54

  I just recieved a shipment of equipment orderd by my predicessor that includes brand new Dell Optiplex 990 computers, with standard mice and keyboards. Also included were Black Box ServSwitch Secure KVMs. I've worked with KVMs before and hypothetically they should be the easiest thing in the world to deal with, plug it all together, push the button, go. However, for the life of me I can't get the computers to recognize the mouse or keyboard when plugged into the KVM. We've seen this with multiple KVMs across the order. Any one know what I'm missing? Computers are all Dell 990 with Windows 7.

• What's the best way to cancel an asynchronous WCF request?

  - by Pwninstein

  (Assuming a WCF method called "MyFunction") Currently, to support canceling a WCF request, I'm using the BeginMyFunction/EndMyFunction methods generated by svcutil (and handling an isCanceled flag when dispatching the results to the main thread). I'd like to use the MyFunctionAsync method (and hooking into MyFunctionAsyncCompleted event instead) for async calls instead of Begin/End. What is the best/supported way to handle canceling WCF requests if using MyFunctionAsyncCompleted, and still ensuring that the event doesn't get fired on a page that's no longer loaded (i.e. page navigation within a frame). Thanks!

• Invoke host's workspace switcher from inside VM

  - by Paul

  When I start a virtual machine (like VMware or VirtualBox) and set it full screen then, from the host OS (in this case Ubuntu), I can beautifully switch to it with the Workspace Switcher. So I switch to the VM like I switch to a virtual screen. But switching back -- from the VM to the host's virtual screens -- seems to be impossible because by entering the VM I loose the host's workspace switcher. Is there a nifty workspace switcher program that runs inside the VM and is able to switch workspaces of the host machine? Edit in light of Frank Thomas' answer, can we configure VirtualBox (or VMware) to not send certain key combinations to the VM, but keep them to the host? Like Super+S. In that approach I would sadly have to miss the nice workspace switcher icon in the guest OS, but that's OK if at least the keyboard trick would work.

• changing src reference based upon https

  - by spody

  I'm adding a facebook comment widget to a website. I'm placing this widget in a file that is included on everypage. The navigation is relatively linked so it switches back and forth from http and https. But for some reason the comment widget only shows up if both the src linked file and webpage is secure or both the src linked file and webpage is NOT secure. The widget does not display of the src file is secure and the webpage is not secure. So... I've tried this but doesn't work. if (window.location.protocol == 'https:') script.setAttribute('src', 'https://ssl.connect.facebook.com/js/api_lib/v0.4/FeatureLoader.js.php'); } else { script.setAttribute('src', 'http://static.ak.connect.facebook.com/connect.php/en_US') }

• How to refresh an activity?

  - by poeschlorn

  Hi Guys, after implementing some Android Apps, including several Map activities, I try to refresh the activity when the GPS listener's onLocationChanged() mehtod is called. I have no Idea how to tell the map activity to refresh on its own and display the new coords... the coords to store will have to be in global values, so that the location listener will have access to it. In my sample GPS-class (see code below) I just changed the text of a text view....but how to do that in map view? private class MyLocationListener implements LocationListener { @Override public void onLocationChanged(Location loc) { final TextView tv = (TextView) findViewById(R.id.myTextView); if (loc != null) { tv.setText("Location changed : Lat: " + loc.getLatitude() + " Lng: " + loc.getLongitude()); } } I think the solution of this Problem won't be very difficult, but I just need the beginning ;-) This whole app shall work like a really simple navigation system. It would be great if someone could help me a little bit further :) nice greetings, Poeschlorn

  I am trying to construct a navigation menu using a Categories table from my db. I have a similar layout as below in Categories table. public List<Category> CategoryData = new List(new Category[] { new Category{ CategoryId = 1, Name = "Fruit", ParentCategoryId = null}, new Category{ CategoryId = 2, Name = "Vegetables", ParentCategoryId = null}, new Category{ CategoryId = 3, Name = "Apples", ParentCategoryId = 1}, new Category{ CategoryId = 4, Name = "Bananas", ParentCategoryId = 1}, new Category{ CategoryId = 5, Name = "Cucumber", ParentCategoryId = 2}, new Category{ CategoryId = 6, Name = "Onions", ParentCategoryId = 2} ); } The above should return something like Fruit (parent) "===Apples, Bananas (child) Vegetables (parent) "===Cucumber, Onions (child) I need to be able to pass this as some kind of 'grouped' (grouped by parentid) collection to my View. How to do this?

• Server 2008 unresponsive after SP2 install.

  - by Dan

  I have a dev server that has an exact image of a production web server. The prod server only has SP1 installed on it. When I first fired up the dev box, the first thing I did was install SP2, and let it be. Almost every morning when I came in, the server was unusable. It would respond to ping, but RDP and the web site running on it were down. On the screen the screen saver was bouncing around, so it wasn't hard locked. But it was unresponsive to keyboard and mouse. So now I have to hard shut it down, but when it comes back up, the only thing in the event viewer is the unexpected shutdown, nothing else. I've since taken a fresh image of my prod box and put it on the dev server, and not installed SP2, and the dev box is humming along perfectly. I should also note that this is Server2k8 Web, 64bit Has anyone else seen anything like this?

• Loading UINavigationController from another nib automatically by UITabBarController

  - by porneL

  I think I've found the cause: Document Info window in IB has a warning: "'Selected Navigation Controller (Second)' has nib name property set to 'SecondView.nib', but this view controller is not intended to have its view set in this manner." Bummer. I've built nib in Interface Builder that has UITabBarController at top level and switches between UINavigationControllers. It works fine when everything is in a single nib file, but I'd like to use separate nib files for UINavigationControllers. Starting with Apple's TabBar template, if I just change class of SecondView to UINavigationController, it all breaks: and all I get is this: Is it possible to have separate file for UINavigationController without programmatically setting everything? I would like TabBarController to handle loading and unloading of nibs.

• Find and raise a window in KDE4 with shortcut

  - by Andre_112

  Hi all! I was wondering about a possibility to find and raise some window in KDE4 with shortcut. Currently in KDE 4.4 there is a possibility to switch to window from krunner (Alt-F2). Say, I have an open konsole widow somewhere and to switch to it, I can Alt-F2, write konsole and choose konsole window I need from the list. This is great, but too much typing. I would like to have a keyboard shortcut to do the same. Maybe some DBUS magic can do that? Any ideas? Thaks! Andre

• Looking for framework for plotting scientific data: 2d/3d ...

  - by Ivan

  I need to visualize some scientific calculations. I generally prefer reusing code if there is already a good available instead of inventing wheels each time, that's why I am asking. I need a C# code to draw charts (just outputting a bitmap is ok) of 2d (y=f(x)) and 3d (z=f(x,y)) digital data sets (where any axis can be float, int or datetime), sometimes combined. If I go here and click 3D in the navigation bar on the left, there I can see what I need. But the cheapest version costs $759 there, looks scary for a hobby project of an east-european student :-(
