I built a little function:
function CashVal (byRef Intext as object, byRef ErrInd as boolean) as double
1. Check Intext to be sure it's not nothing
2. Check Intext to be sure it's not null
3. Check Intext to be sure it's numeric (and in my case, > 0...)
4. Return CDbl(Intext) and an appropriate ErrInd.
I invoke this (x = CashVal(textboxname.text,Error_Indicator) )when the "leave" event is fired, so the user can type anything, and it's evaluated as a whole. The event handler checks to see if there was an error. If not, it sets the text property of the text box to format (x, "currency"). If there's an error, obviously, it can react appropriately.

One of easy ways....
Private Sub TextBox1_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles TextBox1.KeyPress<br />
If (AscW(e.KeyChar) < 48 Or AscW(e.KeyChar) > 57) And Not e.KeyChar = Chr(Keys.Back) Then<br />
e.KeyChar = Nothing<br />
End If<br />
End Sub

Too bad the system doesn't differentiate between them. When a key is pressed, there is nothing in the message to say which keyboard it came from. You'd have to write your own filter driver that sits just above the keyboard drivers to expose something like this. You can't do this in Managed Code. This is the domain of C++ and the Windows Device Driver Development Kit.

If you are going to post all your interview questions why do you post them one at a time? Just post the whole thing and be done with it.

Sorry, I guess I pressed the wrong post. My mistake, I won’t do it again, please forgive me for this if you can possible find it in your heart to do so.

I will, but only if you can forgive me for my impatient replies.
This guy has really stirred me up.
Cheers.

Beacuse I don't know anything about the job, so that I have to ask questions on forums even to be able to fill in the interview form.

If you can't fill this question in yourself, toss the application in the trash and walk away.
Only YOU know if your bringing any skills to the project they can use.

1. Google
2. Google
3. Google
4. Google Groups
5. MSDN
6. Workmates
7. Alternate solution
8. Code Project (so far no need to reach this stage)

In what order?? You're kidding, right?
Do you not know how to do research or tech yourself stuff? You absolutely need this skill if you're going to be a developer, at any level. If you don't have it, your peers are not going to waste their time doing it for you, in ANY job.
