Formating data input

[darksirius]

Hi everyone..

I need help how to accept data in certain input, for example if user input string it will give error msg ( i already got that ), but I need to set it to only accept 6 integer only, not more than that, really hope someone can help figure this out. Cheers

There are several tricks to do that. Here's one of them:

If IsNumeric(TextBox1.Text) Then
   If TextBox1.Text.Trim.Length = 6 Then
      Messagebox.Show("Valid")
   Else
      Messagebox.Show("Numeric but not long enough")
   End If
Else
   Messagebox.Show("Not a 6 digit numeric input.")
End If

Regards,

I got it, i tried like this

If cboDocType.Text = "New IC Num" Then
If txtDocNo.Text.Length <> 14 Then
MessageBox.Show("Please input valid new I.C. number", "Testing", MessageBoxButtons.OK, MessageBoxIcon.Information)
Else
..........

it works fine wif me, but I just wondering if I could combine both the character length and to check the data whether is it numeric or not, should I use or for that purpose. Thanx

the textbox also has a maxlength propertie. So you could use that just set it to 6 or whatever you need.
