• Internet Connectivity... Help please!

  - by James

  Hi. My Laptop is having trouble connecting to my wireless router. Other laptops are using the wireless, but it's not reached capacity. The laptop recognises (with a strong signal) that there is wireless internet, and I can connect via the router with a cable because this happens automatically. My problem is this... When I click "connect" (for example in the network and sharing centre), the dialogue box closes and nothing else happens - as though "connect" is being read as "exit". I am running Vista on a Toshiba Satellite Pro P300. Any help would be very much appreciated, Thanks

• Find a common element within N arrays

  - by kunjaan

  If I have N arrays, what is the best(Time complexity. Space is not important) way to find the common elements. You could just find 1 element and stop. Edit: The elements are all Numbers. Edit: These are unsorted. Please do not sort and scan. This is not a homework problem. Somebody asked me this question a long time ago. He was using a hash to solve the problem. I was thinking if SO has solved similar problems.

• Use Amazon EC2 as a backup server

  - by MikeMurko

  I would like to use Amazon EC2 as an emergency backup database+web server in the event our primary host becomes unavailable. I feel like I wouldn't have trouble setting up a Windows instance, install SQL Server and get the web server up and running (would take a few hours, plus installing various libraries, our source code, etc). My question relates to pricing. If I simply "stop" the instance rather than "terminate" it, does that stop counting "instance-hours"? I would prefer not to terminate the instance and lose all that work I spent setting it up. If I must "terminate" in order to stop the billing - is it possible to make an image of the server after I have set it all up, then save that image somewhere (S3?) Is this something that people do regularly? Ideally this instance would just be waiting in the wings for an issue with our host, but costing us nothing except perhaps data storage costs.

• Word 2007 cell formatting

  - by Michelle Grant

  I have created a form template in Word 2007 which include various fields. Some of the fields are to show time (i.e. 15:47:32). I've set the text field properties as "Date" HH:mm:ss. The trouble arises when the form is them completed. If I input 15.47.32 it correctly reverts to 15:47:32 but if I input 12.12.31 it reverts to 00:00:00. This also happens if I input 12:12:32. Please help as I've looked at this all afternoon now and it's driving me insane

• ViewSonic LCD Monitor Touch-input

  - by Synetech inc.

  I bought a used 15" ViewSonic LCD monitor (VP150m) and noticed that it has a 3.5mm connector on the back labeled “touch i/o”. I’m trying to figure out how to use the touch function but am having trouble finding anything useful. First, I cannot find any information on what kind of cable it uses (TS, TRS, TRRS, etc.), or how to connect it to the computer. Second, I cannot find touch drivers for it—though I can find a page that mentions how easy it is to install them. Does anyone have any information on using the touchscreen function of the VP150m? Thanks a lot.

• Good scalaz introduction

  - by Easy Angel

  Recently scalaz caught my eye. It looks very interesting, but I have not found any good introduction to the library. Seems that scalaz incorporates a lot of ideas from haskell and mathematics. Most articles that I found assume that you already feel comfortable with these concepts. What I'm looking for is gradual introduction to the library and underlying concepts - from simple and basic concepts to more advanced (which basesd in basics). I also looked to the examples, but it's hard for me to find the point where I should start to learn library. Can somebody recommend me some good scalaz introduction or tutorial (that covers basics and advanced concepts)? Or give me starting point in the answer. Thank you in advance!

• Should I still use querystrings for page number, etc, when using ASP.NET 4 URL Routing?

  - by Scott

  I am switching from Intelligencia's UrlRewriter to the new web forms routing in ASP.NET 4.0. I have it working great for basic pages, however, in my e-commerce site, when browsing category pages, I previously used querystrings that were built into my pager control to control paging. An old url (with UrlRewriting) would be: http://www.mysite.com/Category/Arts-and-Crafts_17 I now have a MapPageRoute defined in global.asax as: routes.MapPageRoute("category-browse", "Category/{name}_{id}", ~/CategoryPage.aspx"); This works great. Now, somebody clicks to go to page 2. Previously I would have just tacked on ?page=2 as the querystring. Now, How do I handle this using web forms routing? I know I can do something like: http://www.mysite.com/Category/Arts-and-Crafts_17/page/2 But in addition to page, I can have filters, age ranges, gender, etc. Should I just keep defining routes that handle these variables, or should I continue using querystrings and can I define a route that allows me to use my querstrings like before?

• Why do I have inconsistent network issues with my laptop's wireless?

  - by Jason

  I'm having trouble with my laptop Internet connection. It's patchy at best and resets or freezes a lot. The signal strength is also random. I thought it might be a driver issue but now I don't know. Three other computers using the same wireless network run well. I've switched out wireless routers so I don't think it's the router. I thought it might be the laptop's internal wireless card but I just bought an external USB network card and I'm still having problems. Specs Lenovo T-60p Windows 7 Ultimate Edition Patches/drivers are up to date I only use one of the below at a time, disabling the other: Intel PRO/Wireless 3945ABG v. 13.3.0.137 (Internal wireless) Medialink Wireless-N USB 2.0 Adapter (USB wireless) Any ideas on what might be the problem?

• How do I get the NextVal from an oracle Sequence thru NHibernate

  - by trainer

  I am working on c# .net 4.0 and using NHibernate to talk with an Oracle DB. You would think something as simple as this is already addressed somewhere but sadly its not. I need the NextVal from an Oracle sequence. I do not need to insert it a database as part of an Id or Primary key. I just need to use the next val on the c# side. Can somebody help me out with xml mapping and C# file(or a link) to achieve this. Thanks. Something like int NextValueOfSequence = GetNextValueofSequence(); public int GetNextValueOfSequence() { // Access NHibernate to return the next value of the sequence. }

• sudo rejects password that is correct

  - by Ryan

  sudo (Which I have configured to ask for a password) is rejecting my password (as if I mis-typed it) I am absolutely not typing it incorrectly. I have changed the password temporarily to alphabetic characters only, and it looks fine in plaintext, in the same terminal. I have my username configured thus: myusername ALL=(ALL) ALL I am using my password, NOT the root password, which are distinct. Just to be sure, I've tried both (even though I know the root password is not what I should use) - neither work. I have added myself to the group 'wheel' additionally, and included the following line: %wheel ALL=(ALL) ALL I'm kind of at the end of my rope here. I don't know what would cause it to act as though it was accepting my password, but then reject it. I have no trouble logging in with the same password, either at terminal shells, or through the X11 login manager.

• Cannot access internal network on OSX 10.6.6

  - by cabuki

  Last week, I began having trouble connecting to our internal web servers. Usually, a refresh would take care of it or switching to a different wireless network, but as of yesterday, this wasn't enough. We have an internal DNS server using dnsmasq and a private internal host name (us.lcl). Once I started having more issues with the names not resolving, I tried pinging the server. Using the internal host name (s1.us.lcl), it failed. I tried using the IP address, but that also failed. I have no problems accessing external sites with the exception of it being a bit slower than normal. A reboot yesterday at lunch time after following the instructions here seemed to fix the issue, but when I came into the office this morning, it had stopped working. As of this posting, I cannot ping, ssh or access the web server using the internal host name or ip address. I'm the only one running 10.6 in my office and none of my colleagues has this issue.

• Google Play: how dev can give (already purchased) app to customer as a gift?

  - by Tertium

  Yes, SO, I know, it's not a "programmer's" question:) But customers sometimes help us (devs) with our code, so we (devs) shold be grateful. I think answer to my question will be useful for all fellow android devs. User has purchased my app. Refund period (15min) is over of course. Now I'd like to return money to him as a gift, because he helped me in testing a little. If I refund the entire order in Checkout-Orders will user keep my app 'purchased'? I mean will he be able to uninstall and install it again from GooglePlay-MyApps and will app be marked "purchased"? Will Google LVL accept him to run the app? I've done such refunds before, but then they called it "Android Market", and refund was 12h, and there were no LVL. Maybe somebody know another way to make a small gift using Google Play?

• OS Isolation: Virtualization or Dual-Boot Duplication, a General How To?

  - by Mr_CryptoPrime

  I want to isolate my windows 7 operating system and I have looked into virtualization. This should work with Linux, however, I do want to still have a way to run windows 7 securely, but without significant performance loss, thus eliminating virtualization for that. I know that you can dual boot because I currently do so with my XP/Linux system. Is there a way that I can duplicate my windows 7 system so I can select one at bootup? This way I can ensure that each OS is isolated and not worry about performance loss. However, I am having a lot of trouble finding a solid method for OS duplication?! Is this even possible or must I buy two versions of win7 and somehow install them separately? Any information regarding this would be helpful, thanks! Essentially I want, Two instances of win7 (not necessarily simultaneously running) Each are isolated from one another so that a security breach in one doesn't affect the other. There is no performance loss in either from doing so

• Having onFocus do several things.

  - by Jakob

  So I have this input tag <input ... onFocus=...> and what I want is for a warning popup to come up if somebody clicks to write in the input field. After the person has read the warning he/she closes the popup and can continue to write in the field. I have managed to implement the popup just fine but my problem is that I lose focus on the input field when the popup comes up so the next time I click the field the popup comes back again and im back on square one. The system I work on uses php and javascript so and I cannot use anything other than that to solve the problem and my experience with both php and javascript is limited.

• How do I run perfmon against a remote machine?

  - by WindyCityEagle

  For starters I'm trying to do this from a Windows 7 box to a Windows 7 box. I know the simple answer should be to enter \\computername where it says "Select Counters From Computer". Trouble is, every time I do that I get an error message that says "Unable to connect to machine" I know the machine is out there and accessible, because I can bring up windows explorer and enter \\computername\c$ in the explorer bar and then can browse their c drive. So the machine is out there. Are there special permissions for perfmon? Is here a service which needs to be running on the remote machine?

• In Selenium IDE, can I store an element to use in subsequent asserts?

  - by Colin Fine

  I've just started using Selenium-IDE (not looked at selenium-RC yet: if somebody tells me that that is the answer to my question I'll look at it) One of the operations I'm testing generates some output in a table in the next HTML page, but the order of the rows is not predictable. I can obviously use 'assertTextPresent', but I want to do a bit more, and check that various bits of text are in the same row. What I would like to be able to do is to identify a tr by some content, and then use that tr in subsequent asserts; something like storeExpression //table[@id='TABLE_6']/td[.='case_1']/.. row assertText ${row} 'Some text' assertText ${row} 'Some other text' to check that 'Some text' and 'Some other text' occur in the same table row as 'case_1'. I haven't got this to work so far, and I'm not sure whether it is possible, or what syntax to use if it is. Has anybody managed to do this?

• Resolution is Being Stupid. Help me?

  - by One Terrorist

  I'm having trouble with a new computer I bought a few days ago. I have come to the conclusion that the resolution of the screen is too small, at the moment it is 1024x768 and I think it should be 1280x960, due to a message given at the resolution tab of the control panel. It states: (!) If your resolution is below 1280x960, some items on the screen may not fit on the screen. The computer is an Asus A54H and runs 64-bit operating system with Windows 7 Home Premium. This link has a screenshot of the screen at the moment, the icons and font are too big and are a little stretched. Thank you in advance!

• IB z-order on simulator 6.0

  - by Stanley

  Consider the above's IB objects listing. Siblings further down the list should be on top of the siblings listed further up when rendered on the screen. Under Xcode 4.5.2, everything is ok if iphone simulator 5.1 is used. But for simulator 6.0 the map just covers everything. The same if using actual devices (phones) for testing. Hope that somebody knowledgeable could help. Please also add comments if you do not find such a problem on simulator 6.0. Because chances are the problem is related to how my project is setup. Update : Have setup a test project with the iOS 6 map view. There seems to be no problem with the z-order. So the problem should relate to my code.

• Problem with Xcode and iPhone preference files

  - by CyDummy

  Hi, I created four language files for my app: two for the preferences and two for the strings. I added them into Xcode and it works great on the phone but the string files are shown as "Localizable.strings (de)" and "Localizable.strings (en)", while I have two files called "Root.plist" under the "Settings.bundle" in the groups "de.lproj" and "en.lproj" (see screenshot).When I don't add the two "Root.plist" files instead of "Settings.bundle", I get what I want ("Root.plist (de)" and "Root.plist (en)") but I have no "Settings.bundle" in Xcode. Is somebody out there who can help me to a get what I want?

• Flex: Problem with CollectionEvent on ArrayCollection

  - by dasnervtdoch

  Hi there, got a reference to an arrayCollection and add event listener like this: collection.addEventListener(CollectionEvent.COLLECTION_CHANGE, onCollectionChange); that´s fine. Now some other component does have the same reference and is adding items to and removing items from that collection. Each time the handler is called: private function onProjectPersonsChange(event:Event):void { if (event.kind == CollectionEventKind.ADD) { //do something } else if (event.kind == CollectionEventKind.REMOVE) { //do something //here is the problem: event.items.length = 0 } else { trace('CollectionEvent: kind not handled!'); } } Does somebody know why the removed item is not in 'items'? Thanks in advance!

• Android application: showing overlay items in AsyncTask

  - by user1707887

  I am building an android application that uses google maps to overlay items. The latitude and longitude for the items I get from a MySQL database. To do this I connect to a php script using HTTP in Async Task. My code for displaying items on the map is in the onPostExecute() method of Async Task. Everything works fine but when I for example rotate the phone all my overlayed items disappear. How can I resolve this issue? Should overlaying the items happen in the main thread? If so, I need to somehow pass the information from the async taks to the main thread, which I have looked into but have not been able to get that working. If somebody knows a good and right way to do this, I would really appreciate the help.
