• How do you configure recycle bins on roaming profiles?

  - by Zombian

  I copied the following from a post on the Spiceworks forum which remained unanswered: Is there any way to place the Recycle Bin back on the desktop of a Roaming Profile with the Desktop being redirected? I have used Google and can't find a straight forward answer. I am asking for people with experience in this. This is for a Windows XP machine. I saw mention of needing to use a program such as Undelete but I'm hoping that is not the case. Further explanation: I use redirected folders and whenever a user deletes something from their desktop,my documents it doesn't show up in the recycle bin. It doesn't appear in the recycle bin on the server either. Where is this data? I doubt it is permanently deleted. Is there a way to change the recycle bin on the users' desktop to display those files? Thank you!

• Can I set Windows default second-monitor behaviour to "Extend these displays"?

  - by MT_Head

  I travel to multiple offices (and multiple desks in those offices), and whenever possible I plug an external monitor into my laptop. Whenever I plug in a monitor I haven't used before, Windows defaults to "Duplicate these displays" - which messes up the arrangement of icons on my desktop if the external monitor is a different shape from my laptop's monitor. I then select "Extend these displays", and my laptop screen returns to its original shape - but my icons don't go back to their original arrangement. Grrrrr. Fast-forward a few days or weeks; I've got my icons arranged so I can find stuff again - then I go to a new office and it starts all over again. I'm tired of this. Is it possible to make "Extend these displays" the default behavior? I'm using Windows 8 x64 Home Premium, but I had the same complaint under Windows 7 x64 Ultimate. (Prior to that, I hadn't discovered the joy of dual displays. Ah, the time I wasted...)

• C++, generic programming and virtual functions. How do I get what I want?

  - by carleeto

  This is what I would like to do using templates: struct op1 { virtual void Method1() = 0; } ... struct opN { virtual void MethodN() = 0; } struct test : op1, op2, op3, op4 { virtual void Method1(){/*do work1*/}; virtual void Method2(){/*do work2*/}; virtual void Method3(){/*do work3*/}; virtual void Method4(){/*do work4*/}; } I would like to have a class that simply derives from a template class that provides these method declarations while at the same time making them virtual. This is what I've managed to come up with: #include <iostream> template< size_t N > struct ops : ops< N - 1 > { protected: virtual void DoStuff(){ std::cout<<N<<std::endl; }; public: template< size_t i > void Method() { if( i < N ) ops<i>::DoStuff(); } //leaving out compile time asserts for brevity } struct test : ops<6> { }; int main( int argc, char ** argv ) { test obj; obj.Method<3>(); //prints 3 return 0; } However, as you've probably guessed, I am unable to override any of the 6 methods I have inherited. I'm obviously missing something here. What is my error? No, this isn't homework. This is curiosity.

• application specific seed data population

  - by user339108

  Env: JBoss, (h2, MySQl, postgres), JPA, Hibernate 3.3.x @Id @GeneratedValue(strategy = IDENTITY) private Integer key; Currently our primary keys are created using the above annotation. We expect to support a large number of users (~million users), what key should be used. Should it be Integer or Long or should I use the unsigned versions of the above declarations. We have a j2ee application which needs to be populated with some seed data on installation. On purchase, the customer creates his own data on top of the application. We just want to make sure that there is enough room to ship, modify or add data for future releases. What would be the best mechanism to support this, we had looked at starting all table identifiers from a certain id (say 1000) but this mandates modifying primary key generation to have table or sequence based generators and we have around ~100 tables. We are not sure if this is the right strategy for this. If we use a signed integer approach for the key, would it make sense to have the seed data as everything starting from 0 and below (i.e -ve numbers), so that all customer specific data will be available on 0 and above (i.e. +ve numbers)

• Disable Control-L hotkey on YouTube

  - by Heptite

  I am used to using Ctrll to access my address bar. Unfortunately YouTube "helpfully" defines Ctrll as a hotkey to jump forward several seconds in the currently playing video, so I need a way to stop YouTube from adding that key binding. A Greasemonkey/Scriptish userscript that disables the binding after page load would be acceptable. To be clear, this is while I am on a YouTube video's page, not on a third-party site that has embedded a YouTube video, and the behavior occurs when the Flash player does not have focus. Note: I am aware that Altd does the same as Ctrll in Firefox, but I'm too used to Ctrll and I'd rather not be forced to switch. Edit: OS-specific solutions are less desirable since I use multiple OSes; in-browser solutions are preferred.

• WHY JSLint complains: "someFunction() was used before it was defined"?

  - by 7hi4g0

  Searching for the JSLint error "was used before it was defined" i've found these: JSLint: Using a function before it's defined error Function was used before it was defined - JSLint JSLint: was used before it was defined jsLint error: “somefunction() was used before it was defined” jslint - Should we tolerate misordered definitions? Problem None of those answers WHY the error is shown. Elaboration According to the ECMA-262 Specification functions are evaluated before execution starts, hence all functions declared using the function keyword are available to all the code idenpendent of the place they were declared (assuming they are acessible on that scope). This is otherwise known as hoisting. Douglas Crockford seems to think it is better to declare every function before the code that uses it regardless of the hoisting effect. According to StackOverflowNewbie in his question, this raises some code organization problems. Not to mention some people, like me, prefer to declare their functions underneath the main/init code. On those questions there are some ways to avoid or fix the error, such as using function expressions vs function declarations. But none of them showed me the reason of the error. Not even Crockford's site. Question(s) Why is it an error to call a function before the declaration, even if it was declared using the function keyword? Is it better to use function expressions instead of function declaration in the JSLint context? If one is preferred, why? Note Not looking for answers like: Crockford is a tyrant Is just Crockford's opinion Thank you :*

• Proxy - Some general questions

  - by user68802

  Is it possible to accomplish the following scenario with a proxy server? We are having one internet facing server that we want to put behind a proxy for some reasons. We want everything to work as before. When they do a request all connections will be forward to the internal server which will send back the information through the proxy. We want to be able to change to proxy to show an maintenance page whenever we are doing maintenance and change it back to forwarding traffic when we are done. We do also want to be able to keep forwarding all users that are using the sites but show an maintenance page for all new users for a time before showing the maintenance page for everyone in order to give the users some time to finish their work before kicking them out.

• What is an interface in C (COM) is it the same as a interface in C#

  - by numerical25

  Ok, I know what a interface is, but since I got into C and working with COM objects, it seems an interface in COM is a little different from the interface I know of. So what I am trying to do is bridge the gaps here cause since I been learning C, alot of things have been sounding very familiar to me but are not exactly what they seem. The interface I know of are like contracts. They are objects that have only method declarations, with no body. All classes that implement an interface must include the methods of the interface. The interface I hear about in COM seems to be just pointers. They can not retrieve objects directly but only can retrieve objects through the means of a method. Is this what a COM Interface is ?? If so, then why did they give them the same names if they are completely different. Also I just wanted to add that headers in C++ kind of remind me of the C# Interfaces. Not sure if their are any relations. But anyways, I am just trying to clear that up.

• howt setup remote access into computer behind 2 routers?

  - by Steve Wasiura

  I can setup remote access to a pc behind a single router/firewall by using NAT and Port Forwarding, simples! But there is a customer that shares an internet connection with another office, and they are behind a second router firewall. I drawed a picture with my crayons but I can't attach it because I'm a new account on SF. see it here: http://i.imgur.com/b3FDx.png So how would I setup remote access to the pc that is beind the second firewall? It must be something about static routes, i.e. if I hit the wan ip on port 4905 I want it to forward it to 10.0.0.30 by going through 192.168.1.10 so a route statement like for all requests to 10.0.0.30, use 192.168.1.10 ? and ass u me router 2 has a static gateway ip of 192.168.1.10 and need a standard NAT on router 2 to point port 4905 to 10.0.0.30 is this the right way, any tips? both routers are netgear consumer equipment. thanks

• Win Server 2008 R2 - Mapped shared folder hanging?

  - by M-Tech

  I have recently built a windows 2008 server R2 machine. This is purely for file server purposes and is very much a basic build. All windows updates installed and part of domain. I have setup a shared folder on the C:Drive and added permissions for domain users as co-owners. The client machines run XP SP3 and are part of the domain also. We have a few servers running the same setups on a few of our sites but this one is particular crashes users machines (explorer.exe hangs for at least a few mins) when attempting to access the shared folder. I have turned off the option on the network card for power save aswell still no change. Any help with this is very much appreciated and i look forward to hearing from you ;)

• JBoss behind NAT hostname problem

  - by z0mbix

  My company has a JBoss cluster sitting behind a firewall that performs NAT. We forward ports to JBoss from the firewall, so that our client application can access the server. We are having trouble when JBoss replies it tells the clients to connect to the internal hostname, not the external one with which the initial connection was made. Is this something that is easily resolved/configured? How are other JBoss app servers configured behind NAT firewalls? Split-horizon DNS? Many Thanks

• Is there any way to remotely configure a Microsoft Lync account?

  - by John O

  There are no perl modules for Lync. No open source clients. Windows Powershell can do some things with it, but only on the server on which the server software is installed. It would be useful to be able to forward a certain desk phone number (we use Lync for voip) to a personal cell phone. We can do this from our own desktop machines, but only using the Lync client. It would be nice to be able to have a cron script run that just did rotations, I wouldn't have to carry around the lousy on-call phone with me. communicator.exe doesn't take any useful parameters. Nor are there any obvious function names in the DLLs that would let me just use rundll32.exe to accomplish this. There is a Lync SDK, but no examples of changing phone forwarding, and my Windows 7 machine refuses to install the Silverlight SDK dependency for some reason I can't fathom. Does anyone have any other ideas how I might accomplish this?

• Running multiple lines through a server.

  - by Kevin Roberson

  I am looking to buy numbers in bulk on DIDx.net. After I purchase the numbers in a particular area code, I want to forward those numbers to other numbers that are outside of that area code. This way it will be seen as a local call versus long distance. I have the customers but I don't have the system I need. I have read about Asterisk, VOIP, SIP, and BYOH. But I have no clue what will be the best system for me. Does anyone have any idea what my next step should be when it comes to hardware and software? Or what type of operating system I should use? I basically want to set up a system like GoogleVoice & Phonebooth.

• Serialization of Queue type not working

  - by Soham

  Consider this piece of code: private Queue Date=new Queue(); //other declarations public DateTime _Date { get { return (DateTime)Date.Peek();} set { Date.Enqueue(value); } } //other properties and stuff.... public void UpdatePosition(...) { //other code IFormatter formatter = new BinaryFormatter(); Stream Datestream = new MemoryStream(); formatter.Serialize(Datestream, Date); byte[] Datebin = new byte[2048]; Datestream.Read(Datebin,0,2048); //Debug-Bug Console.WriteLine(Convert.ToString(this._Date)); Console.WriteLine(BitConverter.ToString(Datebin, 0, 3)); //other code } The output of the first WriteLine is perfect. I.e to check if really the Queue is initialised or not. It is. The right variables are stored etc. (I inserted a value in that Queue, that part of the code is not shown.) But the second WriteLine is not giving the right expected answer: It serializes the entire Queue to 00-00-00.

• How do I organize C# classes that inherit from one another, but also have properties that inherit from one another?

  - by Chris

  I have an application that has a concept of a Venue, a place where events happen. A Venue is owned by a Company and has many VenueParts. So, it looks like this: public abstract class Venue { public int Id { get; set; } public string Name { get; set; } public virtual Company Company { get; set; } public virtual ICollection<VenuePart> VenueParts { get; set; } } A Venue can be a GolfCourseVenue, which is a Venue that has a Slope and a specific kind of VenuePart called a HoleVenuePart: public class GolfCourseVenue { public string Slope { get; set; } public virtual ICollection<HoleVenuePart> Holes { get; set; } } In the future, there may also be other kinds of Venues that all inherit from Venue. They might add their own fields, and will always have VenueParts of their own specific type. My declarations above seem wrong, because now I have a GolfCourseVenue with two collections, when really it should just have the one. I can't override it, because the type is different, right? When I run reports, I would like to refer to the classes generically, where I just spit out Venues and VenueParts. But, when I render forms and such, I would like to be specific. I have a lot of relationships like this and am wondering what I am doing wrong. For example, I have an Order that has OrderItems, but also specific kinds of Orders that have specific kinds of OrderItems.

• Running Tomcat 7 and Apache 2 on the same server

  - by Thorn

  Part of my site needs to run over HTTPS and I'm creating a sub-domain for that part. I have apache httpd 2 AND Tomcat 7 running on the same server with the same IP, Apache is on port 80 of course, while Tomcat is running on port 8080. Right now I am doing domain forwarding for requests that need to run off tomcat. For example, mathteamhosting.com/mathApp can forward to mathteamhosting.com:8080/mathApp. I would like to have Tomcat handle the https requests for that subdomain. I don't think this forwarding technique can work in this case. How do I set that up so that Tomcat receives the requests on port 443 while apache handles port 80. To be more specific: http://proctinator.com == request goes to Apache web server https://private.proctinator.com == request goes to Apache web server

• In Java, is there a performance gain in using interfaces for complex models?

  - by Gnoupi

  The title is hardly understandable, but I'm not sure how to summarize that another way. Any edit to clarify is welcome. I have been told, and recommended to use interfaces to improve performances, even in a case which doesn't especially call for the regular "interface" role. In this case, the objects are big models (in a MVC meaning), with many methods and fields. The "good use" that has been recommended to me is to create an interface, with its unique implementation. There won't be any other class implementing this interface, for sure. I have been told that this is better to do so, because it "exposes less" (or something close) to the other classes which will use methods from this class, as these objects are referring to the object from its interface (all public methods from the implementation being reproduced in the interface). This seems quite strange to me, as it seems like a C++ use to me (with header files). There I see the point, but in Java? Is there really a point in making an interface for such unique implementation? I would really appreciate some clarifications on the topic, so I could justify not following such kind of behavior, and the hassle it creates from duplicating all declarations. Edit: Plenty of valid points in most answers, I'm wondering if I won't switch this question for a community wiki, so we can regroup these points in more structured answers.

• iptables block everything except http

• JSF h:outputStylesheet doesn't work everywhere

  - by s3rius

  I'm currently learning Icefaces, now I'm trying to integrate a css file via h:OutputStylesheet into my code. I have a main page and a second page. Using outputStylesheet in my main page works well (and then I can also access the css in the second page, which I guess is intended). But when I try to integrate it in my second page it doesn't work at all. The code for both pages is basically identical. main page: <h:head></h:head> <h:body> <!-- this line works --> <h:outputStylesheet library="css" name="style.css" /> <!-- this line is only shown in red if the outputStylesheet from above is there --> <div class="red">This is red color in main page</div> </h:body> second page: <h:head></h:head> <h:body> <!-- this line doesn't work --> <h:outputStylesheet library="css" name="style.css" /> <!-- this line is only shown in red if the outputStylesheet in main page is there --> <div class="red">This is red color in second page</div> </h:body> I've made sure that I have h:body and h:head tags in both files. There's nothing more in the html pages except the standard doctype and xml version declarations. I've tried packing everything into h:forms, but that doesn't change anything. Can anyone explain to me what's going on?

• C#: at design time, how can I reliably determine the type of a variable that is declared using var?

  - by Cheeso

  I'm working on a completion (intellisense) facility for C# in emacs. The idea is, if a user types a fragment, then asks for completion via a particular keystroke combination, the completion facility will use .NET reflection to determine the possible completions. Doing this requires that the type of the thing being completed, be known. If it's a string, it has a set of known methods; if it's an Int32, it has a separate set of methods, and so on. Using semantic, a code lexer/parser package available in emacs, I can locate the variable declarations, and their types. Given that, it's straightforward to use reflection to get the methods and properties on the type, and then present the list of options to the user. The problem arrives when the code uses var in the declaration. How can I reliably determine the actual type used, when the variable is declared with the var keyword? Just to be clear, I don't need to determine it at runtime. I want to determine it at "Design time". So far the best idea I have is: extract the declaration statement, eg var foo = "a string value"; concatenate a statement foo.GetType(); dynamically compile the resulting C# fragment it into a new assembly load the assembly into a new AppDomain, run the framgment and get the return type. unload and discard the assembly This sounds awfully heavyweight, for each completion request in the editor. Any better ideas out there?

  I'm trying to get Synergy working running as client on my Mac with SynergyKM Preferences panel. It's performing generally fine (just some real slow downs when my network is under heavy use, usually from youtube videos). The main thing I want to get working is none of the special buttons on my mouse are working on the client.. just the scroll and middle click.. but I have back/forward buttons I'd like to have working. Also my Windows Comfort Curve Keyboard has some extra keys and I'd like to know how to set those up to perform operations on my Mac client. I could have sworn that home/end weren't working but they seem to be now.. perhaps it's application specific..
