Pop up box ?

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!!!

:wave:

Put this code in the change Event of the textbox

VB Code:

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

:wave:

In the keypress event , paste this code .

VB 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

thanks i get this error back now

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

Where did you put this code ?

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.
