Answer 1

Use the resizable option

var elem = $("#mydiv");
            elem.dialog({       
            modal: true,
                resizable: false,
            title: 'title',
            buttons: {
                Ok: function() {
                    $(this).dialog('close');                                
                } //end function for Ok button
            }//end buttons
                });  // end dialog  
                elem.dialog('open');

Add resizable: false option.

 var elem = $("#mydiv");
    elem.dialog({       
    modal: true,
    title: 'title',
    resizable: false,
    buttons: {
        Ok: function() {
            $(this).dialog('close');                                
        } //end function for Ok button
    }//end buttons
        });  // end dialog  
        elem.dialog('open');
