No coding necessary. In design set the maxlength property to the desired length.

Edit: After re-reading your question, I'm not sure about number 1. I don't know if you want it to be a maximum length of 100, or only allow numbers up to 100, so in case it is the latter, I'll add this.

VB Code:

Private Sub Text1_KeyPress(KeyAscii As Integer)
If (KeyAscii < 48 Or KeyAscii > 57) And KeyAscii <> 46 And KeyAscii <> 13 Then
    MsgBox "Only numbers are allowed for this entries"
    KeyAscii = 0
    Exit Sub
End If
If Val(Text1.Text) > 100 Then
    Msgbox "A maximum value of 100 is allowed"
   Text1.Text = 100
End If
End Sub
 
'also, in the change event put this code
'to prevent pasting in non numeric text
Private Sub Text1_Change()
If Not IsNumeric(Text1.Text) Then
   MsgBox "Only Numbers Are Allowed"
   Text1.Text = ""
   Exit Sub
End If
If Val(Text1.Text) > 100 Then
    Msgbox "A maximum value of 100 is allowed"
   Text1.Text = 100
End If
End Sub

the first one is a textbox only allow numeric from 0 to 100 only.

the second one is a textbox to validate only 50 characters are allow.
