• Accessing non-static combbox property in the static method.

  - by Harikrishna

  I have one combobox on the window form and I have one method which is declared with static like private static DataTable ParseTable(HtmlNode table) Now I want to use combobox in that method for using combobox property but I can not access any property of combobox or combobox itself.If I made the combobox declaration as static then it can be accessed in that static method.But any alternative way to access combbox property in that static method because I don't want to make combobox declaration as static.

• Are variables in the main methods static.

  - by vaibhav

  Its a well known fact that a static method can work only on static members. public static void Main() { Test t1 = new Test(); } Here the Main method is static, but I haven't declared t1 as static. Is it implicitly static?

• Static member object of a class in the same class

  - by Luv

  Suppose we have a class as class Egg { static Egg e; int i; Egg(int ii):i(ii) {} Egg(const Egg &); //Prevents copy-constructor to be called public: static Egg* instance() {return &e} }; Egg Egg::e(47); This code guarantees that we cannot create any object, but could use only the static object. But how could we declare static object of the same class in the class. And also one thing more since e is a static object, and static objects can call only static member functions, so how could the constructor been called here for static object e, also its constructors are private.

• SH404SEF URLs in Joomla 1.5

  - by Tao Bellamine

  I have two modules to play with urls, the global configuration module and the sh404sef module. The global config is set to "Sef urls: YES" and "mod rewrite enabled: YES" and the sh404sef is set "url optimization: NO". My problem is, even with "Sef urls" set in the global config, my urls still don't seem to be that "user friendly" so I turn on the "Url optimization" using the sh404sef module, and I get better descriptive urls. However, the problem I inherit from doing this is that my dynamically populated chronoforms get messed up (only the chrono forms, other forms are fine); These forms are now showing up at the homepage instead of their own reserved page. Here's an example: Old form "GOOD" url: http://www.mycraftwork.com/index.php?option=com_content&view=article&id=94 New optimized "BAD" URL: http://www.mycraftwork.com/handthrown-pottery/alladin-teapot/index.php?option=com_content&view=article&id=94 Any help would be GREATLY appreciated! I can even turn the sh404sef on and off if some people are interested in seeing the issue LIVE. Thanks!! Tao Bellamine

• One to many problem with implementing 301 redirect after changed urls

  - by user16136

  I have a problem. I had an old dynamic url which I have now split into multiple static urls. e.g. www.mydomain.com/product.php?type=1&id=2 www.mydomain.com/product.php?type=2&id=3 www.mydomain.com/product.php?type=2&id=4, etc which I have changed to something like www.mydomain.com/electronics/radio www.mydomain.com/electronics/television www.mydomain.com/mobile/smartphone, etc. Google has previously indexed the dynamic urls and search results show the old urls. I want search to point to the new urls. I have kept the old url active, so both urls work. How can I set up a 301 redirect in this case? I run IIS and it only allows a page to be redirected to 1 url. Should I deactivate the old dynamic url? In that case I lose all the previous seo rankings..

• static readonly field initializer vs static constructor initialization

  - by stackoverflowuser

  Below are 2 different ways to initialize static readonly fields. Is there a difference between the 2 approaches? If yes, when should one be preferred over the other? class A { private static readonly string connectionString = WebConfigurationManager.ConnectionStrings["SomeConnection"].ConnectionString; } class B { private static readonly string connectionString; static B() { connectionString = WebConfigurationManager.ConnectionStrings["SomeConnection"].ConnectionString; } } Thanks.

  Class Test{ int value; static void* thread_func(void* args){ value++; } void newthread(){ pthread_create(&thread_func,...); } } I'm trying to create a thread in Class Test. Therefore compiler forces me to make thread_func static. However I cannot access the non-static member "value" anymore. It says: invalid use of member 'Class::value' in static member function Is there a way around it?

• Static IPv6 address in Windows unused for outgoing connections

  - by Luc

  I'm running a Windows server and trying to get it to use a static IPv6 address for outgoing connections to other IPv6 hosts (such as Gmail). I need this because Gmail requires a ptr record, and I can't set one for random addresses. The static address is configured on the host, but it also has a temporary privacy address as well as a random address from the router it seems. By default Windows uses the privacy address; it seems this is the expected behavior (and it makes perfect sense for people/users that did not set a static address, but I did!). I've tried disabling the privacy address with: netsh int ipv6 set privacy disabled This indeed gets rid of the privacy address, but I still have the random address that the router assigned. To disable this, it was said I needed to disable "router discovery" using this command: net interface ipv6 set interface 14 routerdiscovery=disabled Upon doing this, all IPv6 connectivity is lost. If I do this while pinging Gmail, it will report "Destination host unreachable" as soon as I enter the command. In the static IPv6 configuration, I did configure the default gateway and prefix length, so I don't see why it's unable to connect. Probably has something to do with the lack of ARP in IPv6 and somehow being unable to resolve the router's MAC, but I wouldn't know how to fix this. Finally I've tried disabling the DHCPv6 lease with these commands: netsh interface ipv6 set interface "IDMZ Team" managedaddress=disabled netsh interface ipv6 set interface "IDMZ Team" otherstateful=disabled Which was to no avail; the host continues to obtain and use the router-assigned IPv6 address. The router is a FritzBox 7340, which shows me all the IPv4 and IPv6 addresses that the host (identified by MAC) utilizes, but I'm unable to change the assigned address. Maybe this could be done over the telnet interface of the router somehow, but again, I wouldn't know how to do this even if it's the way to go. In short, any of the following would probably solve my problem: Change Windows' source address selection behavior. Have Windows not get an address from the router and not generate a privacy address; Have the router hand out a static address and make Windows use that as source address. Recover connectivity after disabling router discovery on Windows. Alternatively I might use some (batch, perl, ...) script to throw away all IPv6 addresses except the desired one, but this feels rather hacky. If it's the only way (or less hacky than another hacky solution), it might be an option though. Thanks!

• Swap static public IPs without creating DNS conflicts?

  - by Jakobud

  Our ISP is Comcast and we have 5 static public IPs from them that we use for various services, including customers connecting to our network, VPN, web, DNS, etc... We need more IP addresses from Comcast. Unfortunately, Comcast is telling us that they can't just simply give us 5 more addresses. They only give static IP addresses in blocks of 1, 5 or 13. In order for us to get more static IPs, they have to take away our current 5 static IPs and give us 13 new ones. How do we make this transition without causing all sorts of DNS chaos? We run public DNS servers, so we can make the DNS changes ourselves, but it will take some time obviously for those DNS changes to propagate throughout the internet. Are there any easy ways to make this transition? Like create some type of fallback DNS entry or something? Surely there must be some sort of procedure for this kind of thing. The Comcast support guy was useless.

• How to handle URLs with diacritic characters

  - by user359650

  I am wondering how to handle URLs which correspond to strings containing diacritic (á, u, ´...). I believe what we're seeing mostly are URLs where diacritic characters where converted to their closest ASCII equivalent, for instance Rånades på Skyttis i Ö-vik converted to ranades-pa-skyttis-i-o-vik. However depending on the corresponding language, such conversion might be incorrect. For instance in German, ü should be converted to ue and not just u, as seen with the below URL representing the Bayern München string as bayern-muenchen: http://www.bundesliga.de/en/liga/clubs/fc-bayern-muenchen/index.php However what I've also noticed, is that browsers can render non-ASCII characters when they are percent-encoded in the URL, which is the approach Wikipedia has chosen, for instance http://de.wikipedia.org/wiki/FC_Bayern_M%C3%BCnchen which is rendered as: Therefore I'm considering the following approach for creating URL slugs: -(1) convert strings while replacing non-ASCII characters to their recommended ASCII representation: Bayern München - bayern-muenchen -(2) also convert strings to percent encoding: Bayern München - bayern_m%C3%BCnchen -create a 301 redirect from version (1) to version (2) Version (1) URLs could be used for marketing purposes (e.g. mywebsite.com/bayern-muenchen) but the URLs that would end being displayed in the browser bar would be version (2) URLs (e.g. mywebsite.com/bayern-münchen). Can you foresee particular problems with this approach? (Wikipedia is not doing it and I wonder why, apart from the fact that they don't need to market their URLs)

• How to 301 redirect from old query string urls to CakePHP Canonical urls?

  - by Daniel Bingham

  I currently have a .htaccess file that looks like this: RewriteCond %{QUERY_STRING} ^action=view&item=([0-9]+)$ RewriteRule ^index\.php$ /index.php?url=item/%1 [R=301] RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{REQUEST_FILENAME} !-f RewriteRule ^(.*)$ index.php?url=$1 [QSA,L] It is meant to 301 redirect my old query string based URLs to new CakePHP urls. This will successfully send users to the correct page. However, Google doesn't seem to like it (see below). I previously tried doing this: RewriteCond %{QUERY_STRING} ^action=view&item=([0-9]+)$ RewriteRule ^index\.php$ /item/%1 [R=301] RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{REQUEST_FILENAME} !-f RewriteRule ^(.*)$ index.php?url=$1 [QSA,L] But that fails. The second rewrite rule doesn't seem to catch the rewritten URL. It goes straight through. Using the first version wouldn't be a problem, except that I suspect that is what is choking up Google. It hasn't indexed my sitemap full of the new URLs. My old sitemap had been fully indexed and all the URLs are in Google's index. But it isn't following the redirects from the old URLs to the new. I have a 'not followed' error for every one of the query urls that was in my old sitemap. Am I properly using a 301 redirect here? Is it the weird rewrite rule? What can I do to send both Google and users to the proper page and save my page rank?

Thanks.

• Clean URLs for images

  - by Albert

  I'm unable to get a working .htaccess that should accept clean URLs to load images. I mean, for example, if a user type this: http://mysite.com/image/example It works perfectly, as my PHP process and parse it. However, if the user type: .../image/example.jpg It doesn't work. I mean, if a user writes that, I want to load the module with the example.jpg as a parameter, I don't want to load the image at all! Thanks in advance.

• Why should I use "Web 2.0"-style URLs?

  - by hydrapheetz

  In short, why use something like http://stackoverflow.com/badges/6/supporter instead of something "simpler" (and subjectively, at that) like http://stackoverflow.com/badges/6/. Even on my own site I've just been using /post/6/ to reference posts (by IDs, even though I still store a slug.) Instead of /post/6/small-rant-on-urls, and in some cases, they can get even more absurd, much more so than is really necessary.

• Ubuntu 8.04 server is not retaining a static IP address

  - by James Pierce

  I recently setup a linux box running Ubuntu 8.04 (to match another server with 8.04). I need to insure that this box has a static IP address and I changed /etc/network/interfaces to set up the static IP address and when I run sudo /etc/init.d/networking restart it works fine for a while, but always reverts back to 10.0.1.24 after being idle for a while. I also tried stopping/removing the dhcp client, but that didn't help. sudo /etc/init.d/dhcp stop sudo apt-get remove dhcp3-client Here is my /etc/init.d/networking: # The loopback network interface auto lo iface lo inet loopback # The primary network interface auto eth0 iface eth0 inet static address 10.0.1.4 netmask 255.255.255.0 broadcast 10.0.1.255 gateway 10.0.1.1 Any thoughts? Thanks.

• Static route in conflict with a default route

  Hi guys, I have a default route configured. 192.168.1.0/24 dev eth1 proto kernel scope link src 192.168.1.1 I'd like to add a static route to pass traffic destined for 192.168.1.51 via a load balancer's redundant virtual interface at 192.168.1.2. ip route add 192.168.1.51 mask 255.255.255.255 via 192.168.1.2 When I try to add the static route I get this error. Error: either "to" is duplicate or "default" is garbage." It doesn't want to add the static route because it's in conflict with the default route. Is there a way around this? Regards Ossan

• Why is this static routing not working ?

  - by geeko

  Greeting gurus, I'm trying to develop a DHCP enforcement extension like Microsoft NAP. My trick to block dynamic-IP requesting machines (that don't meet certain policy) is to strip the default gateway (no default gateway) stated in the IP lease and set the lease subnet mask to 255.255.255.255. Now I need the blocked machines to be able to reach some specific locations (IPs) on the network. To allow for this, I'm including some static routes in the lease. For example, I'm including 10.10.10.11 via router 10.10.10.254 (the one to which the blocked machine that needs to access 10.10.10.11 is connected). Unfortunately, as soon as I set the default gateway to nothing, blocked machines cannot reach any of the added static routes. I also tried classless static routes. Any ideas ? any one knows how MS NAP actually do it ? Geeko

• Modify static variables while debugging in Eclipse

  - by sleske

  As an extension the the question "Modify/view static variables while debugging in Eclipse", I'd like to be able to modify static variables while debugging in Eclipse. For instance and local variables, I can just choose the variable in the "Variables" view of Eclipse, and use the context menu "Change value..." to change the value. This is not possible for arbitrary static variables, because they do not appear in the "Variables" view. What I tried: If you choose "Java / Show static variables" from the triangle menu in the "Variables" view, you can see and modify static member variables of the variables listed in the "Variables view". However, I did not find how to access a static member of a class whose instance does not appear in the "Variables view". You can of course enter a static member as an expression into the "Expression view" (using fully qualified name). Then you can see the value, but the "Expression view" does not have an option to modify the value (it does allow to modify members of an expression, but not the expression itself, even if the expression is a field). So, if I have a static variable like a boolean MyClass.disableAllBugs, is there a way to change MyClass.disableAllBugs during debugging? As an aside: I realize that even having public mutable static fields (i.e. mutable global variables) is very bad style. But some codebases have it, and then it's sometimes useful to modify it while debugging.

It seems that the ip address have set successfully. However, when I plug out the lan cable and then plug it back, the ip address is not set. How can I make it automatically set the static ip when the lan cable is connected?
