Vista - Best practices

Hi everybody.
I´m starting with C# and .NET. So, I have some difficulties with some codes.
I´m already a programmer and I´m migrating from Delphi to C#. My questions
are:

1) Into a form I´ve made my connection string and my SqlConnection variable.
Now, I want use this connection to insert data from the form into table and,
of course, get some data from a table for a search. My doubt is that to much
people adviced me to don´t use DataSets ´cause they´re slow and get to much
system´s memory. So, how do I retrieve and insert this data without
DataSets? I read a lof ot tutorials but each of show a differente manner and
opinion.

2) Is there a manner to use dataBingding without DataSet?

Thanks for help!

William,

The Best practise is not to multipost in dotNet newsgroups.
Use crossposting if you want.

I have answered in an other newsgroup on this message.

Hi Willian,

Answering the first:

You can create a LIST<> of object that can be bindable into some data
components.

Answering the second:

Yes, there is!
The same mentioned above.
