Yay thanks for your quick reply! 
So, if my application 'knows' about plugins that conform to a particular interface for example a "Drawing Interface"...? I could create plugins that enable the user to View a photo and another to Edit a photo..? I mean, my application only needs to know what "type" of plugin it will be, correct? Not "exactly" what it will do?
Thanks for yout time

Hmmm... That's very interesting. I'm always on CodePlex, I'm surprised I haven't already found it. Thanks for that Wes Aday!
I'm reading about it now and will check it out. Oh the excitement!!

I nearly posted this in the Lounge as I think it's far enough from a Programming QuestionTM but decided last minute to put it here:
Is the C# keyword var a good thing or not? Was it added just to make C# closer to VB.NET or is it actually a good thing in its own right? Does it make it easier to write programs or are the actually harder to maintain because the code doesn't make it clear what type the variable is?

I think it's good. It allows me to use anonymous types in queries. And they get converted to normal variables at compile-time, so there's no runtime overhead. As for the variable types, most good IDEs will tell you what type a variable is by hovering the cursor over it.
So I think it's good. 'dynamic' on the other hand -

It still generates a strong type internally, and without it Linq wouldn't really work - so, it's a good thing. It's not really akin to a variant.

Linq is new to me but I can see its advantages in anonymous queries.

Hi,
in my view it is as good as "continue" (or even "goto"): you can use it to your advantage and be fortunate to have it; and you can easily abuse it, it is all up to you.

It was added for Linq.
It gets abused too much.
Only weak programmers use it.

i want to delete a string from right of 10 places
Eg..
String = http://www.bharathretail.com/cyberwing/update_ip.php?gid=4274725472424242
but i want
string = http://www.bharathretail.com/cyberwing/update_ip.php
plz help..

string = string.substring(0,string.length -11)

Instead of removing 10 char from right you can use split function
Because not necessary that always you have 10 characters after “?”,
string path = "http://www.bharathretail.com/cyberwing/update_ip.php?gid=4274725472424242";
string[] ar = path.Split('?');
MessageBox.Show(ar[0]);

either you count in base 21 (that would be unumvigintal), or your example is wrong.
if you want to get rid of the querystring in string s, use s=s.Split('?')[0];

Hi,
I am working on Windows application and I created the validation for English language by using “RegularExpressions”. Now my application need to support Spanish language and my English validations are not working in Spanish.
Please help me what should I do.
Thanks in Advance

If you're just using regexes, then you simply add Spanish-validating regexes to your Resources. Then use something like this:
if(Spanish)
RegexValidate(SpanishRegex);
else if(English)
RegexValidate(EnglishRegex);

Hi
Thanks for reply, but how to write "Spanish-validating regexes".
Because in English we use
"Regex objAlphaPattern = new Regex("[^a-zA-Z]");"
But what I need to write for Spanish.
Thanks

To be honest, I've not gone into regexes in detail. Spanish seems to use the same alphabet, plus some, so you could in theory use the same regex. I just don't know how to include the vowels with an acute accent and diaeresis. Perhaps this link may help

I don't think so. Rather than having lots of conditionals, just pull the regex expressions from a string resource, same as the GUI stuff.

I hadn't thought of that. Thanks for the tip. But how would you handle the case that a user wanted to change languages on the fly, apart from recompiling the application with the correct regex expressions?

I don't know the details and have no experience with the subject, however I do vaguely remember an article showing how a GUI language can be changed on the fly; it was based on those regional DLLs Visual Studio and/or .NET support for internationalization.
One probably would have to come up with another solution if one needed multiple languages on a Form, independent of the GUI language itself. Say a translator app.
