  • unable to apply jquery filter

    Hi I m un-animating a list using this code... function unanimate_li(){ $li.filter(':last') .animate({ height: 'hide', opacity: 'hide' }, 1000, function(){ unanimate_li(); }); $li = $li.not(':last'); } I have set up the li using this code $li = $("ol#update > li"); $li = $li.filter(':gt(4)').filter(':lt('+ size + ')'); Now when i try to do this i cannot get the 5th li(4th on zero based) to remove It removes the sixth li The example here And when the second time i do the update it goes on to infinite loop I cannot understand why

  • Single HTML Table from multiple MySQL tables

    - by David Chouinard
    Hi! I've been struggling for a while with this one; I'll try to explain it here as simply as possible. Consider this MySQL table: +----------+-----------+---------+--------+ |status_id |session_id |pilot_id |present | +----------+-----------+---------+--------+ |1 |61 |901 |1 | |2 |63 |901 |1 | |3 |62 |901 |0 | |4 |62 |902 |1 | |5 |63 |903 |1 | +----------+-----------+---------+--------+ Both session_id and pilot_id are foreign keys making reference to a primary key in another table. The same pilot_id can be associated with different session_id, but every pilot_id-session_id combination is unique. I need to make an HTML table (in PHP) that would display the data like this: +----------+---------+---------+---------+ | |61 |62 |63 | +----------+---------+---------+---------+ |901 |X | |X | |902 | |X | | |903 | | |X | +----------+---------+---------+---------+ Hence, rows are pilot_id and columns are session_id. When a pilot_id-session_id combination has a present value of 1, the corresponding cell should be checked. (ie. when the row-combination is zero or the combination does not exist in the MySQL table, nothing should appear in the HTML table) Phew. Any ideas? Thanks!

  • Function arguments VBA

    - by user1068249
    I have these three functions: When I run the first 2 functions, There's no problem, but when I run the last function (LMTD), It says 'Division by zero' yet when I debug some of the arguments have values, some don't. I know what I have to do, but I want to know why I have to do it, because it makes no sense to me. Tinn-function doesn't have Tut's arguments, so I have to add them to Tinn-function's arguments. Same goes for Tut, that doesn't know all of Tinn's arguments, and LMTD has to have both of Tinn and Tut's arguments. If I do that, it all runs smoothly. Why do I have to do this? Public Function Tinn(Tw, Qw, Qp, Q, deltaT) Tinn = (((Tw * Qw) + (Tut(Q, fd, mix) * Q)) / Qp) + deltaT End Function Public Function Tut(Q, fd, mix) Tut = Tinn(Tw, Qw, Qp, Q, deltaT) - (avgittEffektAiUiLMTD() / ((Q * fd * mix) / 3600)) End Function Public Function LMTD(Tsjo) LMTD = ((Tinn(Tw, Qw, Qp, Q, deltaT) - Tsjo) - (Tut(Q, fd, mix) - Tsjo)) / (WorksheetFunction.Ln ((Tinn(Tw, Qw, Qp, Q, deltaT) - Tsjo) / (Tut(Q, fd, mix) - Tsjo))) End Function

  • Chipmunk warning still present with --release

    - by Kaliber64
    I'm using Python27 on Windows 7 64-bit. I downloaded the source for Chipmunk 6.2.x and compiled Pymunk with --release and -c ming32. Almost zero problems. Lots of path not found cause I'm bad. All prints seem to have disappeared but I get spammed with EPA iteration warnings. I've seen a couple discussions but no solutions. Possible chipmunk betas to fix the float errors causing the double truths causing the warning. I picked the latest stable version I think. My program is seriously bogged down with all the prints. class NullDevice(): def write(self, s): pass sys.stdout=NullDevice() Does not disable the C prints .< Any help?

  • Finding the intersection of two vector equations.

    - by Matthew Mitchell
    I've been trying to solve this and I found an equation that gives the possibility of zero division errors. Not the best thing: v1 = (a,b) v2 = (c,d) d1 = (e,f) d2 = (h,i) l1: v1 + ?d1 l2: v2 + µd2 Equation to find vector intersection of l1 and l2 programatically by re-arranging for lambda. (a,b) + ?(e,f) = (c,d) + µ(h,i) a + ?e = c + µh b +?f = d + µi µh = a + ?e - c µi = b +?f - d µ = (a + ?e - c)/h µ = (b +?f - d)/i (a + ?e - c)/h = (b +?f - d)/i a/h + ?e/h - c/h = b/i +?f/i - d/i ?e/h - ?f/i = (b/i - d/i) - (a/h - c/h) ?(e/h - f/i) = (b - d)/i - (a - c)/h ? = ((b - d)/i - (a - c)/h)/(e/h - f/i) Intersection vector = (a + ?e,b + ?f) Not sure if it would even work in some cases. I haven't tested it. I need to know how to do this for values as in that example a-i. Thank you.

  • How do I check the validity of the Canadian Social Insurance Number in C#?

    - by user518307
    I've been given the assignment to write an algorithm in C# that checks the validity of a Canadian Social Insurance Number (SIN). Here are the steps to validate a SIN. Given an example Number: 123 456 782 Remove the check digit (the last digit): 123456782 Extract the even digits (2,4,6,8th digith): 12345678 Double them: 2 4 6 8 | | | | v v v v 4 8 12 16 Add the digits together: 4+8+1+2+1+6 = 22 Add the Odd placed digits: 1+3+5+7 = 16 Total : 38 Validity Algorithm If the total is a multiple of 10, the check digit should be zero. Otherwise, Subtract the Total from the next highest multiple of 10 (40 in this case) The check digit for this SIN must be equal to the difference of the number and the totals from earlier (in this case, 40-38 = 2; check digit is 2, so the number is valid) I'm lost on how to actually implement this in C#, how do I do this?

  • SQL Server 2008 - Conditional Range

    - by user208662
    Hello, I have a database that has two tables. These two tables are defined as: Movie ----- ID (int) Title (nvchar) MovieReview ----------- ID (int) MovieID (int) StoryRating (decimal) HumorRating (decimal) ActingRating (decimal) I have a stored procedure that allows the user to query movies based on other user's reviews. Currently, I have a temporary table that is populated with the following query: SELECT m.*, (SELECT COUNT(ID) FROM MovieReivew r WHERE r.MovieID=m.ID) as 'TotalReviews', (SELECT AVG((r.StoryRating + r.HumorRating + r.ActingRating) / 3) FROM MovieReview r WHERE r.MovieID=m.ID) as 'AverageRating' FROM Movie m In a later query in my procedure, I basically want to say: SELECT * FROM MyTempTable t WHERE t.AverageRating >= @lowestRating AND t.AverageRating <= @highestRating My problem is, sometimes AverageRating is zero. Because of this, I'm not sure what to do. How do I handle this scenario in SQL?

  • Using a ControlParameter in FilterParameters when the property is null

    - by end-user
    I have a DataList and FormView; they have separate datasources, though they pull the same info. The FormView's datasource has a FilterExpression to pull whatever's been selected on the DataList. On first load, the SelectedValue of the DataList is null (naturally). I expect the FilterExpression to result in zero rows, but it doesn't. If I set the DefaultValue to 0, it does, but then the parameter never updates when I select something from the DataList. Am I doing it wrong?

  • Private IP getting routed over Internet

    - by WernerCD
    We are setting up an internal program, on an internal server that uses the private 172.30.x.x subnet... when we ping the address 172.30.138.2, it routes across the internet: C:\>tracert 172.30.138.2 Tracing route to 172.30.138.2 over a maximum of 30 hops 1 6 ms 1 ms 1 ms xxxx.xxxxxxxxxxxxxxx.org [192.168.28.1] 2 * * * Request timed out. 3 12 ms 13 ms 9 ms xxxxxxxxxxx.xxxxxx.xx.xxx.xxxxxxx.net [68.85.xx.xx] 4 15 ms 11 ms 55 ms te-7-3-ar01.salisbury.md.bad.comcast.net [68.87.xx.xx] 5 13 ms 14 ms 18 ms xe-11-0-3-0-ar04.capitolhghts.md.bad.comcast.net [68.85.xx.xx] 6 19 ms 18 ms 14 ms te-1-0-0-4-cr01.denver.co.ibone.comcast.net [68.86.xx.xx] 7 28 ms 30 ms 30 ms pos-4-12-0-0-cr01.atlanta.ga.ibone.comcast.net [68.86.xx.xx] 8 30 ms 43 ms 30 ms 68.86.xx.xx 9 30 ms 29 ms 31 ms 172.30.138.2 Trace complete. This has a number of us confused. If we had a VPN setup, it wouldn't show up as being routed across the internet. If it hit an internet server, Private IP's (such as 192.168) shouldn't get routed. What would let a private IP address get routed across servers? would the fact that it's all comcast mean that they have their routers setup wrong?

  • VPN Client solution

    - by realtek
    I have several VPN's that I need to establish on a daily basis but from multiple workstations. What I would like to do it have either a server or vpn router that can perform this connection itself and that I can then route traffic through this device or server depending on the subnet I am trying to reach. The issue is that I only use VPN Clients to connect, so I am basically trying to achieve almost a site to site VPN but by using basically a VPN Client type connection from my network. The main VPN Client I use is the Sonicwall Global VPN Client where I initially use a Preshared Key and then it always prompts me for a username and password (not RSA key). My question is, is there any type of linux distro or even a hardware vpn router that can do this and connect to a Sonicwall device as if it were a client? I have tried pfSense which is very good but it fails to connect, probably due to a mismatch of settings. I have tried many others. Even dd-wrt on my router but it does not support whatever protocol Sonicwall uses. (I thought L2TP/IPSec) but it appears it may not be that. Any advice would be great! The other other thing I have thought of that I have not tried yet is Windows Server Routing and Remote Access but I have a feeling that won't work either. Thanks

  • AWS VPC ELB vs. Custom Load Balancing

    - by CP510
    So I'm wondering if this is a good idea. I have a Amazon AWS VPC setup with a public and private subnets. So I all ready get the Internet Gateway and NAT. I was going to setup all my web servers (Apache2 isntances) and DB servers in the private subnet and use a Load Balancer/Reverse Proxy to pick up requests and send them into the private subnets cluster of servers. My question then, is Amazons ELB's a good use for these, or is it better to setup my own custom instance to handle the public requests and run them through the NAT using nginx or pound? I like the second option just for the sake of having a instance I can log into and check. As well as taking advantage of caching and fail2ban ddos prevention, as well as possibly using fail safes to redirect traffic. But I have no experience with their ELB's, so I thought I'd ask your opinions. Also, if you guys have an opinion on this as well, would using the second option allow me to only have 1 public IP address and be able to route SSH connections through port numbers to respective instances? Thanks in advance!

  • PHP File Serving Script: Unreliable Downloads?

    - by JGB146
    This post started as a question on ServerFault ( http://serverfault.com/questions/131156/user-receiving-partial-downloads ) but I determined that our php script was the culprit. So I'm issuing an updated question here about what I believe is the actual issue. I am using a php script to verify permissions and then serve up a file for users of my website to download. Most of the time, this works, but recently one user has been seeing problems with larger downloads. He is only getting ~80% of downloads for files that are 100MB in size. Also, all downloads from this script fail to report a filesize. Further, tests revealed that the same user COULD reliably download each of the failed files if given a direct link (at which point the filesize is reported). Here's the relevant snippet of code that we are using to serve the file: header("Content-type:$contenttype"); $len = filesize($filename); header("Content-Length: $len"); header("Content-Disposition: attachment; filename=".$title.".".$ext); readfile($filename); Note that $contenttype, $filename, $title, and $ext are all set correctly before we get here. These have been triple-checked. None of them are the problem. Also, $len does provide the correct filesize. While researching this issue, I came across this post: http://stackoverflow.com/questions/1334471/content-length-header-always-zero It seems that I am encountering the same issue. When I use the script, I get chunked encoding on the file and no size is set for content-length. I'm hypothesizing that something is going wrong on the large downloads, leading him to get a zero-length chunk before the end of the file. Here's what the headers look like for a direct request: http://www.grinderschool.com/videos/zfff5061b65ae00e8b21/KillsAids021.wmv GET /videos/zfff5061b65ae00e8b21/KillsAids021.wmv HTTP/1.1 Host: www.grinderschool.com User-Agent: Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.2.3) Gecko/20100401 Firefox/3.6.3 (.NET CLR 3.5.30729) Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 Accept-Language: en-us,en;q=0.5 Accept-Encoding: gzip,deflate Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7 Keep-Alive: 115 Connection: keep-alive Referer: http://www.grinderschool.com/phpBB3/viewtopic.php?f=14&p=29468 Cookie: style_cookie=printonly; phpbb3_7c544_u=2; phpbb3_7c544_k=44b832912e5f887d; phpbb3_7c544_sid=e8852df42e08cc1b2250300c2897f78f; __utma=174624884.2719561324781918700.1251850714.1270986325.1270989003.575; __utmz=174624884.1264524375.411.12.utmcsr=google|utmccn=(organic)|utmcmd=organic|utmctr=low%20stakes%20poker%20videos; phpbb3_cmviy_k=; phpbb3_cmviy_u=2; phpbb3_cmviy_sid=d8df5c0943863004ca40ef9c392d371d; __utmb=174624884.4.10.1270989003; __utmc=174624884 Pragma: no-cache Cache-Control: no-cache HTTP/1.1 200 OK Date: Sun, 11 Apr 2010 12:57:41 GMT Server: Apache/2.2.14 (Unix) mod_ssl/2.2.14 OpenSSL/0.9.8l DAV/2 mod_auth_passthrough/2.1 FrontPage/5.0.2.2635 Last-Modified: Sun, 04 Apr 2010 12:51:06 GMT Etag: "eb42d6-7d9b843-48368aa6dc280" Accept-Ranges: bytes Content-Length: 131708995 Keep-Alive: timeout=10, max=30 Connection: Keep-Alive Content-Type: video/x-ms-wmv And here's what they look like for the request answered by my script: http://www.grinderschool.com/download_video_test.php?t=KillsAids021&format=wmv GET /download_video_test.php?t=KillsAids021&format=wmv HTTP/1.1 Host: www.grinderschool.com User-Agent: Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.2.3) Gecko/20100401 Firefox/3.6.3 (.NET CLR 3.5.30729) Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 Accept-Language: en-us,en;q=0.5 Accept-Encoding: gzip,deflate Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7 Keep-Alive: 115 Connection: keep-alive Cookie: style_cookie=printonly; phpbb3_7c544_u=2; phpbb3_7c544_k=44b832912e5f887d; phpbb3_7c544_sid=e8852df42e08cc1b2250300c2897f78f; __utma=174624884.2719561324781918700.1251850714.1270986325.1270989003.575; __utmz=174624884.1264524375.411.12.utmcsr=google|utmccn=(organic)|utmcmd=organic|utmctr=low%20stakes%20poker%20videos; phpbb3_cmviy_k=; phpbb3_cmviy_u=2; phpbb3_cmviy_sid=d8df5c0943863004ca40ef9c392d371d; __utmb=174624884.4.10.1270989003; __utmc=174624884 HTTP/1.1 200 OK Date: Sun, 11 Apr 2010 12:58:02 GMT Server: Apache/2.2.14 (Unix) mod_ssl/2.2.14 OpenSSL/0.9.8l DAV/2 mod_auth_passthrough/2.1 FrontPage/5.0.2.2635 X-Powered-By: PHP/5.2.11 Content-Disposition: attachment; filename=KillsAids021.wmv Vary: Accept-Encoding Content-Encoding: gzip Keep-Alive: timeout=10, max=30 Connection: Keep-Alive Transfer-Encoding: chunked Content-Type: video/x-ms-wmv So the question is...what can I do to make downloads from the script work properly?

  • Making change recursively: How do I modify my algorithm to print all combinations?

    - by cb
    I have an algorithm that recursively makes change in the following manner: public static int makeChange(int amount, int currentCoin) { //if amount = zero, we are at the bottom of a successful recursion if (amount == 0){ //return 1 to add this successful solution return 1; //check to see if we went too far }else if(amount < 0){ //don't count this try if we went too far return 0; //if we have exhausted our list of coin values }else if(currentCoin < 0){ return 0; }else{ int firstWay = makeChange(amount, currentCoin-1); int secondWay = makeChange(amount - availableCoins[currentCoin], currentCoin); return firstWay + secondWay; } } However, I'd like to add the capability to store or print each combination as they successfully return. I'm having a bit of a hard time wrapping my head around how to do this. The original algorithm was pretty easy, but now I am frustrated. Any suggestions? CB

  • Resize an asp.net panel width based on a checkboxlist?

    - by larryq
    Hi everyone, I have an asp.net panel that contains a checkboxlist. I'd like to resize it so that its width fits the list's contents snugly. Right now I'm handling the panel's pre rendering event, setting its width to match that of the checkboxlist. However it appears the checkboxlist's width property reads zero (at least in this pre render method) so the panel's width is set identically, which leads to inconsistent renderings in Firefox vs IE. Does anyone have a better approach to doing what I'm attempting here? Many thanks.

  • Unable to access network resources through VPN

    - by fbueckert
    I'm currently attempting to connect one of our computers in the office to a client VPN. My development machine is running Windows 7, and can connect and see resources just fine. The problem computer is running Windows XP. They're both within the same network. Using the same credentials at both computers, the VPN connection (using the built in Windows network connections) works just fine. So far, so good. An IP address is assigned, and comparing both machines shows they're still in the same subnet. The problem is that the XP machine cannot see ANY of the computers in the client network. I tried a tracert to a target machine on the Windows 7 box, and the first item that comes up is the .0 address. Pinging it gives responses. Trying it on the Windows XP machine, however, comes up with just timeouts. Trying to trace to www.google.com allows the address to resolve (probably part of the cached resolutions), but results in just timeouts. I double-checked to make sure that the Windows firewall was not on, and trying to open the settings brings up a notification that the firewall service wasn't running, which leads me to believe that it's definitely not on. From my best guess, I've managed to connect the XP machine to a black hole of some sort. There's obviously something strange going on, but I'm not sure where I should be looking.

  • Can't authorize a server for Amazon RDS

    - by Parris
    We are attempting to slowly migrate a website over to AWS among other things. We decided the first thing to move was the database. We have some dedicated server with a different hosting provider. We only have one IP. I am having trouble authorizing the ip so that the old server can connect to RDS. It simply hangs for a while while using the mysql cli, then responds: ERROR 2003 (HY000): Can't connect to MySQL server on 'db.address.us-east-1.rds.amazonaws.com' (110) It did work on my laptop though. I am not quite sure what is wrong. I have a feeling I don't quite understand CIDR/IP. I simply took the ip address and tacked on /32 at the end. Then I gleaned some information that it also has to do with subnet mask? ifconfig reports: 255.255.255.0 I found a calculator and the IP changed a bit and had /24 at the end. That still didn't work. One other note... perhaps i dont know enough about the differences between OS. The hosting provider is using centOS, while our development machines are all ubuntu. Any insight would be extremely helpful! THANKS :)

  • WiFi & GbE Slow while Both Active.

    - by Mark Tomlin
    I'm having a problem with my WiFi network connection when I use my wired GbE connection concurrently on my Laptop. I'm using my WiFi for Internet access, and general web surfing and I'm using my GbE connection to connect to my PlayStation so I can stream media. The WiFi connection is via a Linksys 610N connected to my Cable Modem. Where as the GbE connection is a direct connection from my Ethernet port to the Ethernet port of the PS3 via a Cat-5 cable (no router in between this connection). As soon as I connect the cable from the PS3 to my Ethernet port on my Laptop the WiFi connection slows to a halt, but then allows for a connection to the web as normal but at much slower speeds for the things like BitTorrent that stops completely. It seems to me that Windows can't handle both connections at once. It will have both active but it can only accept and send packets on one device at one time. I can get WiFi connections to work to go to websites and the like, but once I use my GbE connection to share media between my Laptop and my PS3 the Wifi connection dies out and I no longer have access to the internet. I setup my connection on the PS3 and the Laptop following the insturctions posted here: http://forums.finalgear.com/problems/s14e01-ps3-size-problem-40642/#post1188132 And the following is the results of my ipconfig.

  • Window screenshot using WinAPI

    - by Evl-ntnt
    How to make a screenshot of program window using WinAPI & C#? I sending WM_PAINT (0x000F) message to window, which I want to screenshot, wParam = HDChandle, but no screenshot in my picturebox. If I send a WM_CLOSE message, all waorking (target window closes). What I do wrong with WM_PAINT? May be HDC is not PictureBox (WinForms) component? P.S. GetLastError() == "" [DllImport("User32.dll")] public static extern Int64 SendMessage(IntPtr hWnd, uint Msg, IntPtr wParam, IntPtr lParam); ..... SendMessage(targetWindowHandle, 0x000F, pictureBox.Handle, IntPtr.Zero);

  • cross-user C# mutex

    - by Martin
    My app is forced to use a 3rd party module which will blue-screen Windows if two instances are started at the same time on the same machine. To work around the issue, my C# app has a mutex: static Mutex mutex = new Mutex(true, "{MyApp_b9d19f99-b83e-4755-9b11-d204dbd6d096}"); And I check if it's present - and if so I show an error message and close the app: bool IsAnotherInstanceRunning() { if (mutex.WaitOne(TimeSpan.Zero, true)) return (true); else return (false); } The problem is if two users can log in and open the application at the same time, and IsAnotherInstanceRunning() will return false. How do I get around this?

  • std::map default value for build-in type

    - by Qifa Zhao
    Recently, I was confused by the std::map operator[] function. In the MSDN library, it says: "If the argument key value is not found, then it is inserted along with the default value of the data type." I tryed to search much more exactly explanation for this issue. For example here: std::map default value In this page, Michael Anderson said that "the default value is constructed by the default constructor(zero parameter constructor)". Now my quest comes to this:"what the default value for the build-in type?". Was it compiler related? Or is there a standard for this issue by the c++ stardard committee? I did a test on visual studio 2008 for the "int" type, and found the "int" type is construted with the value 0.

  • When are you truly forced to use UUID as part of the design?

    - by Pyrolistical
    I don't really see the point of UUID. I know the probability of a collision is effectively nil, but effectively nil is not even close to impossible. Can somebody give an example where you have no choice but to use UUID? From all the uses I've seen, I can see an alternative design without UUID. Sure the design might be slightly more complicated, but at least it doesn't have a non-zero probability of failure. UUID smells like global variables to me. There are many ways global variables make for simpler design, but its just lazy design.

  • C++/MFC: Handling multiple CListCtrl's headers HDN_ITEMCLICK events

    - by raph.amiard
    I'm coding an MFC application in which i have a dialog box with multiple CListCtrls in report view. I want one of them to be sortable. So i handled the HDM_ITEMCLICK event, and everything works just fine .. Except that if i click on the headers of another CListCtrl, it does sort the OTHER CListCtrl, which does look kind of dumb. This is apparently due to the fact that headers have an ID of 0, which make the entry in the message map look like this : ON_NOTIFY(HDN_ITEMCLICK, 0, &Ccreationprogramme::OnHdnItemclickList5) But since all the headers have an id of zero, apparently every header of my dialog sends the message. Is there an easy way around this problem ?
