That is something that's best left up to the database. If you're using a Integer for a primary key, there are autonumbering columns you can use. The only other acceptable method of generating a key would be if it was gen'd from the database being inserted into the table.
Again, this question belongs in the SQL forum, not the VB.NET forum.

Hi Friends,
How to transfer datas from one computer to another computer using VB.NET.Kindly help me please.
Thanks in Advance

Your question does not make any sense. You need to give us some more detail before anyone can help.
Why use VB, why not use:
Mapped drive
Sneaker net - disk
sneaker net - USB key
print it and give it to the other user.
Secure FTP
Never underestimate the power of human stupidity

How can i use VB.Net or C# to make a touch screen application?

Assuming your touch screen hardware acts like a mouse, sure. I do it all the time. Failing that, you'll need a driver and could probably access it with interop.
(I'm not being sarcastic; I really do work on applications that run on XPe and Windows Mobile based system which use touch screens. I'm so used to it, that when I was working on my daughter's laptop, I kept touching the screen and wondering why it didn't work. Odd since I never do that with a desktop--it must be the portable mindset.)
Anyone who thinks he has a better idea of what's good for people than people do is a swine.

How is that.
I mean how it can be done

Magic.
(Many touch screens act just like a touch pad on a laptop--the drivers are part of the OS. You don't worry about it.)

System.Magic is only in .NET 3.5 though. I could really use Shazaam() in my current windows app. As it stands, I'm having to use some workarounds in System.Illusion. And we all know Illusion is not as good as Magic.

Okey dokey - did you miss that honking great piece of red text at the top when you posted this question? I mean - it's obviously very difficult to see; what with saying "No programming questions in the lounge". Perhaps it was a little bit too subtle.

Now you've done it. His tiny excuse for a brain won't be able to cope with all these metaphors and sarcastic remarks - it will overheat and explode.

Did this jerkoff really first post this in the lounge?!?

He's so pathetic most of the time I think it's a joke account.

What I find amusing is the assumption that the VB forum is the best place to help someone who asks in the lounge ( OK, he said VB or C#, and so it had to be one or the other )

Why would you ask this ? You plainly don't have access to a touchscreen, or you'd know it just acts like a mouse. I rolled out a touch screen version of our app without even having access to one, all I had to do was make places you need to click all big enough to be fingertip friendly.

Does anyone know how to add buttons to a form dynamically.
Ex:
I am getting information from a database. It could return 1 item or 50. I want to be able to created a button on the screen no matter how many items are returned.
Right know I have this but it does not work. It only creates one button because I have not figured out a way to change the new Button's name.
For Each row In Me.UwPdataset.Level1.Rows
btn = New Button
cmbobxLevel1.Items.Add(row(0).ToString)
btn.Location = New Point(lastbtnX + 120, lastbtnY)
Controls.Add(btn)
btn.Text = row(0).ToString
btn.Width = 120
btn.Height = 120
lastbtnX = lastbtnX = 120
Next
Does anyone know how to do this.
