If your application has only one user, ever, then there's no issue with data traffic. So, ask the database. If your app has more than one user, then this approach is a disaster, so you need to ask the database to assign a number, and create the record, so the number doesn't get used twice.

you could do 'select' to get your last entry or have somewhere in your database where you keep localID value

The new id is probably an identity field in your data set. The best way to get the correct id value will be to commit the updates to the database, otherwise you will have concurrency issues.
If you really want to get the last id value from the DataTable look into the Select method.

what do you think 'Add' takes as parameter? It got to be an Image Object. Don't you think?

ListView is just a collection of, well, items. You got your selected index, kewl, now go get your Item. What kind of object is your item? Is it am image? if not not what do you need to do to convert it to Image? Now take that Image object and give it Add().
I'm not working on windows forms, but it does not take much to figure it out. What I said may not be entirely correct, but should give you general idea.

Buy a book on C#, read it, and start with the basics. Abandon what you're doing now, you obviously don't know enough to do it well. I assume you're not being paid for it ?

You may want to go back and read what Christian wrote.
There is nothing wrong with been new and wanting to learn. But the way to learn is first to read and understand the basics.

Either you're biting off more than you can chew, or you're trying to do paid work before you know your basics. Either way, stop it.

Hi..
I have a form which is like following:
Sup.Id: tbox1
S.Name:tbox6 ->When i select 1 it should populate the textbox6 with the proper name? how to do that?
Prod_Name: listbox1...It should only show product name once not twice how to do that?
Prod_Type: listbox2 -> How to view only product type e.g. F,H and T
CostPrice: tbox4 -> It should calculate from product table?
Prod.TradePrice:tbox5
Now as you see i have two tables Suppliers and Products..
In products table i have e.g.
p.name=prodA
p.type=F
p.Price=100
p.name=prodA
p.Type=H
p.Price=50
Suppliers Table:
S.id=1
S.Name=InStock
I will be very thankful to you pls help out...

I have many applications which are using a named instance of SQL Server. They all worked fine until the DBAs reinstalled the sql server. Now the apps can not create connection to the sql server. The exception does not really help--even googling. Exception is Instance Failure.
I tried everything but nothing seems to work. It is a C# app and the config file does not contain double slashes. Here it is:
connectionString="Data Source=MainServer\NamedInstance;Initial Catalog=Shipping;Integrated Security=True";
I replace the MainServer by the IP address as some people suggested but no luck. Any ideas? What causes this?
