Well, it all comes down to how we define what a unit is, a method, a class or a module? I often find class is a good candidate as a unit, but the granularity really is relative.
Also, it would be desirable to test a method in the context of an object, as the object state often has decisive effect on the method itself. Maybe that is one area where C++ differs than C.
Best,
Jun

I see this is new in .NET 2.0. This would have been handy on a post-hoc unit testing assignment I worked on a few months back.

I actually tried that - It looked extremely promising, however it didn't seem to work. It threw up a warning about not being able to find the assembly referenced in the Attrbute and when I tried to access it from the test class it still complained that it was private.
The assemblies are all strong named, so I'm guessing I'm just not doing something right when I give it the strong name of the "friend" assembly.

I'm not sure this solution will work for you, Colin, but one thing I've done for classes that are typically single instance only classes is something like this:
public class SomeClass()
{
private static SomeClass instance = new SomeClass();
private SomeClass()
{
}
public SomeClass Current
{
get
{
return instance;
}
}
}
This way, SomeClass can still implement interfaces necessary for using mocks (whereas static classes cannot implement interfaces), it can be instanciated (using reflection or Activator.CreateInstance), and is quite easier to test than a pure static class. In fact, I only use static classes for places that have totally, 100% "functional" functions; where each function relies only on itself or other functions in the same static class; no variables or shared state at all. If you find yourself requiring lots of state and shared data; go with an instance class, IMO.
If you need static access to the instance class and you need only 1 instance of the class, the above code works well.

You could inherit the singleton and put the [Test] blocks on the new class which does have a public method. Or you could wrap the public constructor of your singleton within #if DEBUG directives causing a compile time error on release mode if someone misused your class.

You want a font combo box. I'm sure there are some on this site, if you do a search.

Ok, now I think I see what you mean.
I've never bothered to look at the "Script" combobox in the FontDialog, but I think the only effect of selecting a different value from the combobox is to show a different set of characters in the preview window.
Unicode charsets contain ranges of special characters (for example, Greek, Kyrillic (sp?) or Hebrew characters) and I think the "Script" refers to one of these groups.
But I don't have an idea if you can get a list of these groups with .NET, sorry...

You can use FontDialog
FontDialog dlg = new FontDialog();
if (dlg.ShowDialog()==DialogResult.OK)
{
selectedFont = dlg.Font;
}

Hi People,
I would like to write a program in c# which will interogate all incoming webpages for bad language etc before allowing it to displayed by the browser.
Trouble is I have no idea where to begin. Can anyone point me in the right direction with articles or advice?
cheers

Well, I would begin by ignoring the browser entirely.
You should start any project like this with the "engine" part. In your case this engine takes a string (which may later be the HTML sent to the browser), and parses that string for a known database of "bad words" or phrases.
It might remove these bad words from the input string, replace them with something, or totally dis-allow the entire input string....that is the bit you decide.
When your engine works to your satisfaction, start to think about how to implement your engine - you suggest you could intercept incoming HTML and do something with it before it hits the browser. That is certainly possible, but will require a good solid knowledge of the inner workings of the OS, the browser and HTTP.
In addition, if you are writing a contant filter, much work is done internationally around standardising such protocol. Many websites, for example, include a header with some form of content rating. You should research this as appropriate to your project.

Thanks for your help. Im not too concerned about writing the engine part at the moment but more the actual intercepting of HTTP and stopping it from reaching IE is more of a concern. Any idea how to do this?

You can try to hook WINSOCK calls and change the content or prevent it.

Apparently you do know where to "begin" since you already decided on the platform (.NET) and language you will use.

This is a huge subject. If you want to create a "filter" for a specific browser like I.E. then you can create a plug-in. For other browsers I don't know, they probably support something similar. If you want to "filter" the entire machine you need something more like a fire wall process.

Your application will be the proxy to the web. Then setup will be as simple as having the user change the connection settings. The proxy would listen, on oh lets just say localhost:27002 then you can be the intermediary filtering all relevent information.

Search the web for simple HTTP proxy servers. An excelent sample in your case would be Privoxy, altough it's not coded in C#.

Hi,
My worker thread looks a bit like this:-
private void CacheThread()
{
while (true)
{
lock (myobject)
{
myobject.DoSomeWork();
}
try
{
System.Threading.Thread.Sleep(100);
}
catch (ThreadInterruptedException)
{
}
}
}
The thread spends the majority of it's time sleeping. Another thread uses Thread.Interrupt() to wake it up when it is necessary to DoSomeWork().
The majority of the time, it's fine - the thread is in the sleep and is interrupted.
But sometimes, I get an unhandled ThreadInterruptedException on the lock() line.
I presume that internally, CLR is using a win32 WaitFor... function, and is interupted. But I don't want my thread to wake up until it can claim the lock.
Is there an alternative? I want to wake the thread from my sleep, but not from a lock()-induced sleep.
Thanks
Jon

You get the exception because you are trying to interrupt the thread while it's not sleeping. If you want to handle that, you will have to catch the exception while the thread is working too.
-- modified at 7:02 Tuesday 11th July, 2006
On second thought, that could be a bit messy. A better way would be to add a flag to the class that you set while the thread goes into sleep mode, and a property that returns the flag so that you can use it to determine if the thread is sleeping or not, so that you don't interrupt it while it's not sleeping.
