Pop up box ?

[TheOneWhoLearns]

Hello People,

i have a text box which only allows 2 digits to be entred, is there any way i can have a message box show if the user tries to enter 3 numbers?

or put some code on my button which checks to see if there is a value in the text box, at the moment if i click the enter button it crahses my programe, i would like it to say u have to enter a value first, so this cannot happen

Thank you people!!!

Put this code in the change Event of the textbox

If textbox1.text.length > 2 then 
messagebox.show("you're not allowed to enter more than 2 digits")
end if

Thanks thats working great now, also could i limit the field size so only numbers 1 to 49 can be inputted?

do u know how i could validate the button cos at the moment if the user clicks the enter button without putting any data into the text boxes it crashes my programe?

Thanks

In the keypress event , paste this code .

Dim KeyAscii As Integer
KeyAscii = Asc(e.KeyChar)
'only allow numbers, a single decimal point, backspace or enter 
 
Select Case KeyAscii
Case Asc("0") To Asc("9"), Asc(ControlChars.Back)
'acceptable keys 
e.Handled = False
 
Case Asc(ControlChars.Cr)
'enter key - move to next box
txtInterest.Focus()
e.Handled = False
 
Case Asc(".")
'check for existance of decimal point
If InStr(txtDeposit.Text, ".") = 0 Then
e.Handled = False
Else
e.Handled = True
End If
Case Else
e.Handled = True
End Select

'Handled' is not a member of 'System.EventArgs'.

Yeah got that working now, if i click the button now without any entries in the text boxes then it doesn't crash the programe, although if i put one entry into the textbox and then leave the others empty and click it, it still crashes!

Is there any way i can do this so that, it only performs its fucnction once all the textboxes have data in them, and if not it puts a pop up saying you must fill in all the text boxes?


Thank You!

Lose that message box about not entering 3 digits and just set the textbox's MaxLength property to 2.

Then you can query the number without worrying about the length of the data.
