* Analyze assemblies for any web references. The drawback here is that not everything is a web reference and I'm not sure how WCF connections are listed. However, this would at least be a start for finding 80% of the connections. Does anyone know of any tools that can do that analysis? Like I said, I've used Reflector for assembly references but can't find anything for web references.

out what is being called and where from. We are looking at enterprise tools that could help but it would be a while before they are implemented (and cost a lot). But is there anything out there that could help out quickly and cheaply? One tool in particular (AmberPoint) can tap into IIS on the servers and monitor inbound and outbound traffic, adds a little special sauce and begin to build a map of the traffic. Very nice, but costs a bundle.

You need a service registry (UDDI??)... If you had a means to catalog these services and their consumers, it would make this job of dependency discovery a lot easier. That is not an easy solution, though. It takes time and documentation to get a catalog in place.
I think the quickest solution would be to query your IIS logs and find source URLs which originate from your own servers. You would at least be able to track down which servers your consumers are coming from.

You are right about AmberPoint. There are other tools that catalog the service traffic and provide reports showing what is happening to your services. Systinet, SOA Software and Actional also has a products similar to Amberpoint but Amberpoint has a free-ware version, I believe. | [

In C++, what alternatives do I have for exposing a collection, from the point of view of performance and data integrity?
My problem is that I want to return an internal list of data to the caller, but I don't want to generate a copy. Thant leaves me with either returning a reference to the list, or a pointer to the list. However, I'm not crazy about letting the caller change the data, I just want to let it read the data.

[RichQ's answer](https://stackoverflow.com/questions/44693/in-c-what-alternatives-do-i-have-for-exposing-a-collection-from-the-point-of-vi#44734) is a reasonable technique, if you're using an array, vector, etc.
If you're using a collection that isn't indexed by ordinal values... or think you *might need to* at some point in the near future... then you might want to consider exposing your own iterator type(s), and associated `begin()`/`end()` methods:

that into your own data structures. The problem is somewhat simplified if you only care about a subset of time zones, for example just in the USA, but if you need all global time zones, you have a lot of work to do, and then the code has to be updated every few years when the laws change. Even the new time zone objects in the latest version of .NET will require windows updates to keep them correct as laws change.

We're currently building an application that executes a number of external tools. We often have to pass information entered into our system by users to these tools.
Obviously, this is a big security nightmare waiting to happen.
Unfortunately, we've not yet found any classes in the .NET Framework that execute command line programs while providing the same kind of guards against injection attacks as the IDbCommand objects do for databases.

Has anyone used ADO.NET Data Services as a data source for Adobe Flex applications? If so, any success stories or tragedies to avoid? If you did use it, how did you handle security?
I use WebORB for .NET to do Flex remoting and then use DLINQ on the server. One tricky thing about using LINQ with WebORB is that WebORB uses Reflection to automatically retrieve all the relationships of the object(s) you return to Flex. This causes severe time penalties as LINQ uses lazy loading to load relationships. To prevent this from happening, I do something like the following:
Override your DataContext's | [

constructor and add the following code:
```
this.DeferredLoadingEnabled = false;
DataLoadOptions dlo = new DataLoadOptions();
dlo.LoadWith<Order>(q => q.Payments);
dlo.LoadWith<Order>(q => q.Customer);
this.LoadOptions = dlo;
```
This tells the DataContext to disable deferred loading of relationships and specifically instructs it to load just the relationships you want, without lazy loading. That way, WebORB isn't causing any lazy loading to happen through Reflection and the number of relationships being transferred to Flex is kept at a minimum.
Hope this helps you in some way. It's definitely one of those little "gotchas" when working with Flex/WebORB and LINQ. | [

Is there any efficiency difference in an explicit vs implicit inner join?
For example:
```
SELECT * FROM
table a INNER JOIN table b
ON a.id = b.id;
```
vs.
```
SELECT a.*, b.*
FROM table a, table b
WHERE a.id = b.id;
```
Performance wise, they are exactly the same (at least in SQL Server).
PS: Be aware that the `IMPLICIT OUTER JOIN` syntax is deprecated since SQL Server 2005. (The `IMPLICIT INNER JOIN` syntax as used in the question is still supported)

Can you cast a `List<int>` to `List<string>` somehow?
I know I could loop through and .ToString() the thing, but a cast would be awesome.
I'm in C# 2.0 (so no [LINQ](http://en.wikipedia.org/wiki/Language_Integrated_Query)).
.NET 2.0 has the `ConvertAll` method where you can pass in a converter function:
```
List<int> l1 = new List<int>(new int[] { 1, 2, 3 } );
List<string> l2 = l1.ConvertAll<string>(delegate(int i) { return i.ToString(); });

Is it currently possible with pre release of ironruby to run rubygems? It seems as if I have to set an environment variable to find them?
You've been able to run rubygems under IronRuby for quite a while now. Simply download and install the latest [IronRuby from codeplex](http://www.codeplex.com/Wikipage?ProjectName=ironruby), and run `igem` on the command line

I have a "showall" query string parameter in the url, the parameter is being added dynamically when "Show All/Show Pages" button is clicked.
I want the ability to toggle "showall" query string parameter value depending on user clicking the "Show All/Show Pages" button.
I'm doing some nested "if's" and `string.Replace()` on the url, is there a better way?
All manipulations are done on the server.
**p.s.** Toran, good suggestion, however I HAVE TO USE URL PARAMETER due to some other issues.
Just to elaborate on Toran's answer:
Use:
`<asp:HiddenField ID="ShowAll" Value="False" runat="server" />`
To toggle your state:

I'm wanting to parse a string into a nullable int in C#. ie. I want to get back either the int value of the string or null if it can't be parsed.
I was kind of hoping that this would work
```
int? val = stringVal as int?;
```
But that won't work, so the way I'm doing it now is I've written this extension method

public static int? ParseNullableInt(this string value)
{
if (value == null || value.Trim() == string.Empty)
{
return null;

but it worked out about the same. I'm more interested in knowing if there is a built-in framework method that will parse directly into a nullable int?
`int.TryParse` is probably a tad easier:
```
public static int? ToNullableInt(this string s)
{
int i;
if (int.TryParse(s, out i)) return i;
return null;
}
```
**Edit** @Glenn `int.TryParse` is "built into the framework". It and `int.Parse` are *the* way to parse strings to ints. | [

Ok, I asked a question earlier about Flex and ADO.NET Data Services but didn't get much response so I thought I'd rephrase. Does anyone have any experience building Adobe Flex applications with a .NET back-end? If so, what architecture did you use and what third-party tools if any did you employ. I've read a little about doing Flex remoting with WebORB but it seems more complicated than it should be, are web services an adequate alternative?
I've mainly used plain ASP.NET pages that return XML for situations that are mainly one-way (data from ASP.NET --> Flex/Flash) communication. The Flex side just | [

uses a URLLoader to hit the ASP.NET page and loads the result as XML.
If the communication needs to be a little more two-sided (sending more than a couple parameters to ASP.NET lets say), I have used standard ASP.NET webservices.
I've never used WebOrb or Flex remoting because I've never really needed that type of interaction between the server and the SWF.

public interface ISomething{
void method();

void method2();

Ideally, you shouldn't be changing your interfaces very often (if at all). If you do need to change an interface, you should reconsider its purpose and see if the original name still applies to it.

still feel that the interfaces will change, and the interfaces changes are small (adding items) and you have control of the whole code base, then you should just modify the interface and fix all the compilation errors.
If your change is a change in how the interface is to be used, then you need to create a separate interface (most likely with a different name) to support that alternative usage pattern.
Even if you end up creating ISomething, ISomething2 and ISomething3, the consumers of your interfaces will have a hard time figuring out what the differences are between the interfaces. When should | [

I have a small local network. Only one of the machines is available to the outside world (this is not easily changeable). I'd like to be able to set it up such that ssh requests that don't come in on the standard port go to another machine. Is this possible? If so, how?
Oh and all of these machines are running either Ubuntu or OS X.
Another way to go would be to use ssh tunneling (which happens on the client side).
You'd do an ssh command like this:
```
ssh -L 8022:myinsideserver:22 paul@myoutsideserver
```
That connects you to the machine that's accessible from the outside (myoutsideserver) | [

and creates a tunnel through that ssh connection to port 22 (the standard ssh port) on the server that's only accessible from the inside.
Then you'd do another ssh command like this (leaving the first one still connected):
```
ssh -p 8022 paul@localhost
```
That connection to port 8022 on your localhost will then get tunneled through the first ssh connection taking you over myinsideserver.
There may be something you have to do on myoutsideserver to allow forwarding of the ssh port. I'm double-checking that now.

Short version: What is the cleanest and most maintainable technique for consistant presentation and AJAX function across all browsers used by both web developers and web developers' end-users?
* IE 6, 7, 8
* Firefox 2, 3
* Safari
* Google Chrome
* Opera
Long version: I wrote a [web app aimed at other web developers](http://con.appspot.com). I want my app to support the major web browsers (plus Google Chrome) in both presentation and AJAX behavior.
I began on Firefox/Firebug, then added conditional comments for a consistent styling under IE 6 and 7. Next, to my amazement, I discovered that jQuery does not behave identically in IE; so | [

I [changed my Javascript to be portable on FF and IE](http://github.com/jhs/app-engine-console/commit/4fe7741ad1856208b565eeab4260a64933929c01) using conditionals and less pure jQuery.
Today, I started testing on Webkit and Google Chrome and discovered that, not only are the styles inconsistant with both FF and IE, but Javascript is not executing at all, probably due to a syntax or parse error. I expected some CSS work, but now I have more Javascript debugging to do! At this point, I want to step back and think before writing piles of special cases for all situations.

as understandable and maintainable as possible. I prefer if this works with no server-side intelligence; however if there is a advantage to, for example, check the user-agent and then return different files to different browsers, that is fine if the total comprehensibility and maintainability of the web app is lower. Thank you all very much!
I am in a similar situation, working on a web app that is targeted at IT professionals, and required to support the same set of browsers, minus Opera.
Some general things I've learned so far:

Make sure you have time for this in your development schedule.
* Toolkits can get you part of the way to cross-browser support, but will eventually miss something on some browser. Plan some time for debugging and researching fixes for specific browsers.
* If you need something that's not in a toolkit and can't find a free code snippet, invest some time to write utility functions that encapsulate the browser-dependent behavior.
* Educate yourself about known browser bugs, so that you can steer your implementation around them.
A few more-specific things I've learned:
* Use conditional code based on the user-agent only as a last | [

resort, because different generations of the "same" browser may have different features. Instead, test for standards-compliant behavior first — e.g., `if(node.addEventListener)...`, then common non-standard functions — e.g., `if(window.attachEvent)...`, and then, if you must, look at the user-agent for a specific browser type & version number.

document.createElement and element.setAttribute. While not standard (and kinda yucky), using node.innerHTML with strings that contain bits of HTML seems to be more reliable across browser types. I have yet to find a toolkit that will let you use element.setAttribute to add a 'name' to a form element in IE.
* CSS differences (and bugs) are just as important as JS differences.
* The 'core' Javascript features (String, Date, RegExp, Array functions) seem to be pretty reliable and consistent across browsers, especially relative to the DOM/CSS/Window functions. There's some small joy in the fact that the language isn't entirely different on every platform. | [

I have a Tomcat Filter that delegates requests to the a handling object depending on the URL. This is the only filter in the `FilterChain`. I have an Ajax app that hammers this filter with lots of requests.
Recently I noticed an issue where the filter's `doFilter` method is often called with a committed response as a parameter (Internally, it is the coyote response that is marked committed).
It seems to me that the only way that this can happen is if the `recycle()` method is not called on this coyote response. I have checked to make sure that I am not | [

Let's say that I want to have a table that logs the date and the number of columns in some other table (or really any sort of math / string concat etc).
```
CREATE TABLE `log` (
`id` INTEGER NOT NULL AUTO_INCREMENT ,
`date` DATETIME NOT NULL ,
`count` INTEGER NOT NULL ,
PRIMARY KEY (`id`)
);

Is it possible to have the count column calculated for me whenever I do an insert?
e.g. do something like:
```
INSERT INTO log (date='foo');
```
and have count calculated by mysql.
Obviously I could do it myself by doing a query to get the count and inserting it, but this would be better.

What's the recommended source control system for a very small team (one developer)?
Price does not matter. Customer would pay :-)
I'm working on Vista32 with VS 2008 in C++ and later in C# and with WPF. Setting up an extra (physical) server for this seems overkill to me.
Any opinions?

* good enough (see disadvantages below),
* simple,
* works fine on Windows (and Linux too),

* You don't have to worry about maintenance of one more box.

that SVN has a few disadvantages :).
It is slow on large repositories
--------------------------------
SVN (or its client -- TortoiseSVN) has one **big** disadvantage -- it terrible slow (while updating or committing) on large (thousands of files) repositories unless you have [SSD](http://en.wikipedia.org/wiki/Solid-state_drive) drive.
Merging can be difficult
------------------------
Many people complain about how hard merging is with SVN.
I do merging for about 4 years (including about 2 years in CVS -- that was terrible, but doable) and about 2 years with SVN.
And personally I don't find it hard -- on the other hand -- any merge is easy after merging branches in CVS :).

of large repository (two repositories in fact) once a week and rarely I have conflicts which are hard to solve (most of conflicts are solved automatically with *diff* software which I use).
However in case of project of a few developers merging should not be problem at all if you keep a few simple rules:
* merge changes often,
* avoid active development in various branches simultaneously.

Many devs recommended [Distributed Version Control](http://en.wikipedia.org/wiki/Distributed_revision_control_system) like [Git](http://git-scm.com/) or [Mercurial](https://www.mercurial-scm.org/).
From **single developer** perspective there are only a few important advantages of DVCS over SVN:
* DVCS can be faster.
* You can commit to local repository | [

without access to central one.
* DVCS is hot thing and fancy to use/learn (if someone pay for your learning).
And I don't think merging is a problem in case of single developer.
Joel Spolsky wrote [tutorial about Mercurial](http://hginit.com/) which is definitively worth to read.
So, despite of many advantages of DVCS I would stay with SVN if merging or speed is not a problem.
Or try Mercurial, which according to [this](https://stackoverflow.com/questions/995636/popularity-of-git-mercurial-bazaar-vs-which-to-recommend) and [this](https://stackoverflow.com/questions/2550091/best-support-now-on-windows-mercurial-or-git) SO questions, is better supported (in July 2011) on Windows.

branches for each Euler problem are really nice feature -- exactly as it is described as advantage of DVCS.
Today Git tooling on Windows is much, much better then 2 or more years ago.
You can use remote repo (like GitHub or ProjectLocker and many others) to keep
copy of your project away from your workstation with no extra effort/money.
However I use GUI client only to looks at diffs (and sometimes to choose files to commit),
so it's better to not afraid of command line -- it's really nice.
So as of today I would go with Git. | [

I'm using Eclipse 3.4 and have configured the Java code formatter with all of the options on the *Comments* tab enabled. The problem is that when I format a document comment that contains:
```
* @see <a href="test.html">test</a>
```
the code formatter inserts a space in the closing HTML, breaking it:
```
* @see <a href="test.html">test< /a>
```
Why? How do I stop this happening?
This is not fixed by disabling any of the options on the *Comments* tab, such as *Format HTML tags*. The only work-around I found is to disable Javadoc formatting completely by disabling both the *Enable Javadoc comment formatting* and *Enable block comment formatting* options, | [

which means I then have to format comment blocks manually.
I can only assume it's a bug in Eclipse. It only happens with *@see* tags, it happens also for all 3 builtin code formatter settings.
There are some interesting bugs reported already in the neighbourhood, but I couldn't find this specific one.

When we create stored procedures in Visual Studio (with the extension .sql) the file encoding is automatically set to 'Unicode (UTF-8 with signature) - Codepage 65001'.
This causes ours DBA's problems as their scripts don't like it.
We have to manually go in and change them to 'Western European (windows) - Codepage 1252'.
This only seems to be happening since we upgraded to VS 2008 from 2005. Can anyone explain whats going on and how to stop it?

How can you do a streaming read on a large XML file that contains a xs:sequence just below root element, without loading the whole file into a XDocument instance in memory?
Going with a SAX-style element parser and the [XmlTextReader](http://msdn.microsoft.com/en-us/library/system.xml.xmltextreader.aspx) class created with [XmlReader.Create](http://msdn.microsoft.com/en-us/library/system.xml.xmlreader.create.aspx) would be a good idea, yes.

Are there conventions for function names when using the Perl Test::More or Test::Simple modules?
I'm specifically asking about the names of functions that are used to set up a test environment before the test and to tear down the environment after successful completion of the test(s).

I dont think there are any such conventions out there.
The only way you can do it is perhaps use BEGIN/END blocks, if the resources are to be used over the whole file.
The general approach I take is to put related tests in one code block and then initialize the variables/resource etc there. You can perhaps keep | [

an easy count of how many tests you have for each function.
Something like ...

# If you want to set some global db setting/file setting/INC changes etc

# Tests functionality 1...
{
# have fun ....
}
# Tests functionality 2...
{

C# doesn't require you to specify a generic type parameter if the compiler can infer it, for instance:

//the type is inferred from the lambda expression
//the compiler knows that it's taking an int and

Why doesn't C# support this class level generic type inference?
Actually, your question isn't bad. I've been toying with a generic programming language for last few years and although I've never come around to actually develop it (and probably never will), I've thought a lot about generic type inference and one of my top priorities has always been to allow the construction of classes without having to specify the generic type.
C# simply lacks the set of rules to make this possible. I think the developers never saw the neccesity to include this. | [

Actually, the following code would be very near to your proposition and solve the problem. All C# needs is an added syntax support.
```
class Foo<T> {
public Foo(T x) { … }
}
// Notice: non-generic class overload. Possible in C#!
class Foo {
public static Foo<T> ctor<T>(T x) { return new Foo<T>(x); }
}
var x = Foo.ctor(42);
```
Since this code actually works, we've shown that the problem is not one of semantics but simply one of lacking support. I guess I have to take back my previous posting. ;-) | [

Example
I have `Person`, `SpecialPerson`, and `User`. `Person` and `SpecialPerson` are just people - they don't have a user name or password on a site, but they are stored in a database for record keeping. User has all of the same data as `Person` and potentially `SpecialPerson`, along with a user name and password as they are registered with the site.

How would you address this problem? Would you have a `Person` table which stores all data common to a person and use a key to look up their data in `SpecialPerson` (if they are a special person) and User (if they | [

There are generally three ways of mapping object inheritance to database tables.
You can make one big table with all the fields from all the objects with a special field for the type. This is fast but wastes space, although modern databases save space by not storing empty fields. And if you're only looking for all users in the table, with every type of person in it things can get slow. Not all or-mappers support this.
You can make different tables for all the different child classes with all of the tables containing the base-class fields. This | [

is ok from a performance perspective. But not from a maintenance perspective. Every time your base-class changes all the tables change.
You can also make a table per class like you suggested. This way you need joins to get all the data. So it's less performant. I think it's the cleanest solution.
What you want to use depends of course on your situation. None of the solutions is perfect so you have to weigh the pros and cons. | [

In Java, what would the best way be to have a constantly listening port open, and still send upon receipt of a packet. I am not particularly savvy with network programming at the moment, so the tutorials I have found on the net aren't particularly helpful.
Would it make sense to have the listening socket as a serversocket and run it in a separate thread to the socket I'm using to send data to the server?

If you can afford the threading, try this (keep in mind I've left out some details like exception handling and playing nice with threads). You may want to look into `SocketChannels` and/or NIO async sockets / selectors. This should get you started.

int port = 10000;

I use TortoiseSVN to access file based local repo. In all my commits an author is my Windows login name. Is it possible to use different name?
I know how to change author after commit but how to change before? Installing apache/svnserver is not an option.
Yes, it's possible.
*TortoiseSVN* and the [*svn*](http://subversion.tigris.org/) command line client share the same settings location in your profile folder. So you may simply checkout one version using *svn.exe*:

I wrote an Active X plugin for IE7 which implements IObjectWithSite besides some other necessary interfaces (note no IOleClient). This interface is queried and called by IE7. During the SetSite() call I retrieve a pointer to IE7's site interface which I can use to retrieve the IHTMLDocument2 interface using the following approach:

IUnknown *site = pUnkSite; /* retrieved from IE7 during SetSite() call */
IServiceProvider *sp = NULL;
IHTMLWindow2 *win = NULL;
IHTMLDocument2 *doc = NULL;

I am working in Visual Basic 6 and need to sort by multiple columns in a ListView. For example, sorting a list of music tracks by artist, then album, then track number. As far as I know, VB6 does not support this out of the box. Here are the suggestions I have already heard:
* Sort the data in a SQL table first and display the data in the resulting order
* Sort the data in an ADO recordset object in memory
* Sort by the primary column and then perform a sort algorithm on the items, moving them around into the correct | [

I want to use the [Publish.GacRemove](http://msdn.microsoft.com/en-us/library/system.enterpriseservices.internal.publish.gacremove(VS.80).aspx) function to remove an assembly from GAC. However, I don't understand what path I should pass as an argument.
Should it be a path to the original DLL (what if I removed it after installing it in the GAC?) or the path to the assembly in the GAC?
**UPDATE:**
I finally used [these API wrappers](http://blogs.msdn.com/junfeng/articles/229649.aspx).
I am using the `GacInstall` to publish my assemblies, however once installed into the gac, I sometimes delete my ‘temporary’ copy of the assemblies.

the original path. This is causing a problem since I cannot seem to get the `GacRemove` method to uninstall the assemblies unless I keep the original files.
Conclusion: Yes, you need to specify the path to the original DLL. (And try to not move/delete it later). If you delete it, try to copy the file from the GAC to your original path and you should be able to uninstall it using `GacRemove`. | [

How would you dynamically subscribe to a C# event so that given a Object instance and a String name containing the name of the event, you subscribe to that event and do something (write to the console for example) when that event has been fired?
It would seem using Reflection this isn't possible and I would like to avoid having to use Reflection.Emit if possible, as this currently (to me) seems like the only way of doing it.
**/EDIT:** I do not know the signature of the delegate needed for the event, this is the core of the problem

contravariance seems like a good plan, I can not make the assumption necessary to use this solution
You can compile expression trees to use void methods without any arguments as event handlers for events of any type. To accommodate other event handler types, you have to map the event handler's parameters to the events somehow.
