u can also do this on keypress event of text box
Private Sub txt1_KeyPress(KeyAscii As Integer)
dim strValid as string
strValid = "1234567890"
if instr(strValid , chr(keyAscii)) = 0 then
keyAscii = 0
end if
end sub
It would help u not to enter any character other than numeric values

Rather than annoy the user with a popup message which theyneed to discard every time they type an incorrect character, you should really restrict the characters that can be entered in the first place.
There are plenty of articles/posts on this subject here at CP if you search.

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.

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.
