Yeah me too. Actually, C# generics should be an improvement over our C++ templates; templates are nothing but "exalted macros" as I once read, with the compiler swapping values in at compile time. C# generics will have a JIT'd version of the actual generic code you write, and reuse that JIT'd code across all the types of that generic class.
Fun fun fun stuff. I just hope it will be released in the spring or summer this year.

You can always use a generic collection or list class like ArrayList. It won't give you strongly-typed params (also, C# isn't strongly-typed, .NET is), but .NET is a true object-oriented framework and adding, for example, a Control to an ArrayList (which accepts Objects) is still a Control in the list. GetType (inheritted from Object) will always return the right Type.
I realize this is probably not what you want and as Colin said, .NET 2.0 (due to release in late 2004 I would imagine, since the end of the year was the release date for 1.0 and 1.1) will include generics. I just wanted to point out that you don't need to worry about using appropriately Typed parameters. After all, when you extend the CollectionBase class and use either List or InnerList (and if you don't, then don't waste time by deriving from CollectionBase), both of those are an instance of the same ArrayList.

You can also use Chris Sells' excellent CollectionGen in the meantime.

You can create a windows control and put a button+datagrid in it or subclass datagrid or datagridcolumn and start from there.

Is there any build in functionality to parse standard query string like this:
string1=hello+dear+friend%21&string2=otherdata+here+%25%26
Anything in the framework?
If not I'll write it, should I put it here as an article?

If you're trying to parse the query string from an ASP.NET page (like an .aspx file), you can use Request.QueryString or Request.Params (combination of POST and GET variables). When getting the value from the parameter dictionary, the values are automatically decoded.
Otherwise, there is many ways this can be parsed, like using String.Split with the &, the doing the same to split the key/value pairs using the = character. The HttpUtility class has both a UrlDecode and UrlEncode method, both overloaded.

Thanx for the tip, but unfortunatly "UrlDecode" didn't work ok with some national characters like 'Ö'. So I wrote my own, and it works ok, using Uri.HexDecode.

The problem is simple:
I need to launch the default mail client (mailto: won't help here), open a new message and add some attachments to it. I need to do the same as when the user right-clicks a file and selects "Send to->Mail recipient". I need a solution that works for all mail clients and not just Outlook... and I need it quickly

Thanks, but your solution is not the answer which I wished.

This is what the items in the Send To menus of most application work. It uses MAPI, and that's the only way to talk to multiple mail clients because it's a set of interfaces (contracts) by which supporting clients communicate. If his solution isn't what you want, then read about MAPI and implement your own solution, but you won't find another abstract way; MAPI is the abstract API that Microsoft developed for this very purpose.

Hi there,
I have started to learn C# last week for a project. I'm starting to get the philosophy of the language. It's not so hard.
I have a project to design that will run Excel 2003.
I have installed the Office 2003 extensions for VS .NET 2003.
For my project, I want to use the following Excel 2003 functionnalities:
- read/write Excel files (worksheets and workbooks) and also use the file import manager (for reading formatted text files, like excel does)
- Input data in a sheet (from a grid in the application)
- insert and retrieve data in sheets (to display them in a grid in the app)
- use Excel 2003 statistical functions
- display an Excel 2003 chart (this chart is calculated by excel, and the application displays the result in a dialog box for example)
- communicate with Excel WITHOUT the fact that excel is running
I wanna do all of these in a stand alone application while Office 2003 will be installed on the target machine.
This application won't RUN Excel!!! It will USE it!
I see that Excel 2003 can be accessed via C#.
Can any one tell me if it's possible to do these things?
And also, can you show me where I can get links with sample code to do basic calls to Excel 2003 functionalities and retrive the results via C#? 
Thanks to all.
Best regards.

Have you try to import Outlook Express Message List/Mail Object or other COM component which exist and usable in c# too?
