Simple Is numeric statement :mad:

Hi guys,

Want 2 know some simple code for stopping alphabetical data being entered into a textbox. And allowing numerical data :thumb:

Got any ideas, my last try was:

VB Code:

Private Sub txtContactno_KeyPress(KeyAscii As Integer)
    If IsNumeric(Chr(KeyAscii)) Then    ' For some reason this doesn't work
        KeyAscii = 0
    End If
End Sub

You need to pass two parmameters first one is "keyascii" and second is textbox name

VB Code:

Public Sub OnlyNumeric(ByRef KeyAscii As Integer, Txt As TextBox)
        Select Case KeyAscii
            Case 48 To 57
                IntPosition = InStr(1, Txt.Text, ".")
                If IntPosition > 0 Then
                    If Len(Txt.Text) - InStr(1, Txt, ".") = 4 Then
                        KeyAscii = 0
                    Else
                        KeyAscii = KeyAscii
                    End If
                End If
            Case 8
            Case 46
                    If InStr(1, Txt, ".") Then
                        KeyAscii = 0
                    Else
                        KeyAscii = KeyAscii
                    End If
                
            Case 45
                    
                    If InStr(1, Txt.Text, "-") Then
                        KeyAscii = KeyAscii
                    Else
                        KeyAscii = 0
                    End If
            Case Else
                KeyAscii = 0
            End Select
End Sub

the above code is backwards, it stops numerics
try

VB Code:

If Not IsNumeric(Chr(KeyAscii)) Then
        KeyAscii = 0
    End If

You might want to try the link to my NumberBox control in my signature.

Dear Martin

Ya it is true, said codes are belong to your control exactally, but it is clear in my mind only to help some one and i hav't the reference of these code.
