hey!

I need help with my VB programme! I was wondering if any of you guys know how to validate a text box?

I need to validate a text box so it only excepts numbers.

Thanks

use either the _validate event or _lostfocus

then put this in it

if Not IsNumeric(text1.text) THen
Msgbox("Must be numeric")
text1.setfocus
end if

alternatively, you could say:

Private Sub txtText1_KeyPress(KeyAscii As Integer)
Select Case KeyAscii
Case 48 To 57, 8 'allows numbers and backspace
Case Else
KeyAscii = 0
MsgBox "Please Enter a Number"
End Select
End Sub
