Thanks. I have that link already. But explanation in that is not clear enough.

the "where TYPE : BuisnessBase<type,key>"
says that the TYPE-parameter must be a "BuisnessBase<type,key>" object or derived from this.
the "where TYPE : new()" just says that the TYPE-parameter does have an constructor without arguments (default-constructor) - therefore you can create TYPE-objects with new.
If you delete the new() - option you will not be able to compile somthing like
TYPE obj = new TYPE(); so if you need to create TYPE-objects in you class you have to provide the new()-where clause.

Great. It worked.. Thanks for clearing that. BTW, can you point out some uses of generics other than implementing collections ?
|
|
|
|

Well everywhere you have some functionality that is common for more than one object.
Of course the major uses are collections and in most cases you might use interfaces instead of type-parameters but if you keep it in mind you will find plenty of uses.
As an example: imagine you want to implement some sorting-algorithm that is independent of the objects to sort.
You can use the generic interface IComparable<t> to do this.

Collections are certainly the most common use for generics. However, they can be used in a lot of different domains. Take the case of a custom business object that needs to declare a "key". All of your objects derive from an abstract base type whose "key" field is a generic type. This allows you the flexibility of each concrete object to use it's own data type for that "key" field.
Another example is in the .NET Framework itself with the use of EventHandler<T> which allows you to declare an event handler and define it in terms of the EventArgs class that it uses.

Hello,
I want to create word files and also want to track changes in WORD from DOT NET. How can I achieve this.

Either integrate word into your application or use something like ASPOSE.Word.
|
|
|
|

ASPOSE.WORD seams to be a paid version. I am thinking of writing my own code. Could you please direct me some URLs where they show to "Integrate word" in the application.

Hi all... I have a strange issue since a couple of days.
here is my code:
<br />
DataRow row = MyDataView[Position].Row;<br />
row["LastName"] = "r";<br />
Now the strange thing is that row.RowState is always set on "Unchanged"... And naturally that means I can't update my modification to the database...
Does somebody have an idea where to look for?

But I still have the problem that when I go to my Update on the dataset, I retrieve a ConcurrencyException... but I'm the only one using this database...

this might be not related to C#, but i would like to know the reason why ALOGOL-60's assign operator (x:=5,//not x=5) was not followed by the other languages like C# and java .

I think (in fact someone told me some time ago) because C language's (i.e. the grandfather of both Java and C#) assignment, equality test operator pair ({=, ==}) is smarter than ALGOL-60 one (({:=, =}): it implies less typing since assignments are statistically more frequent than equality tests.
If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

Possibly because they were based on C style syntax. Pascal use the := syntax, C doesn't.

Maybe Bell Labs didn't have a colon on their keyboards? (Or card punch systems?)
BCPL uses := for assignement and = for equality.
B uses = for assignment and == for equality.
and it all goes downhill from there.
In my opinion, assignment should be := and equality should be == and a bare = should not be a valid token.
