Hi,
On a keypress of textbox write this code

Private Sub TextBox1_KeyPre ss(ByVal sender As Object, ByVal e As System.Windows. Forms.KeyPressE ventArgs) Handles TextBox1.KeyPre ss
if( e.KeyChar.IsDig it = False) then
e.KeyChar=""
end if
End Sub

hi i hope you still need this one,

in txtbox1 view code:

if isnumeric(txtbo x1.text) then
messagebox.show ("Please enter a valid format")
txtbox1.focus
txtbox1.text="" ' to delete or remove the current character entered by the user,

Hi,

i think you should also think whether the user will be able to enter backspace or not.

In the key press event handler, you can check to see if (e.KeyChar != (char)8)...

Cheers
