You need a function that returns a result indicating whether you want to continue with your call procedure.

Public Function check_fill_for_New() as Boolean
    If tb_UserName.Text = "" Then         
        MsgBox("Please Insert User Name Field", _
                MsgBoxStyle.OkOnly,_
                "Error")   

        tb_UserName.Focus()          
        return True 
    Else
        return False
    End If
End Sub 


Private Sub bt_Ok_Click(ByVal sender As System.Object, _
                        ByVal e As System.EventArgs) Handles bt_Ok.Click   

    If maintain_department = "Admin" Then
        If (check_fill_for_New()) Then
            MsgBox("nooooooooo")        
         End If
    End If
 End Sub
