Some jQuery to check button disabled attach keydown event and trigger click

$(document).keydown(function (event) {
if (globalPageMode == 'edit') {
if (event.ctrlKey && event.keyCode == 83) {
if ($("#ButtonSave").is(':disabled') == false) // is the button enabled

Java Script Mouse position for IE, FF, Safari

function eventHandler(e){
// IF NOT IE then e else if IE then window.event
var event = e || window.event;
var IE = document.all ? true : false;
if (IE) { // grab the x-y pos.s if browser is IE
tempX = event.clientX + document.body.scrollLeft;
tempY = event.clientY + document.body.scrollTop;
}

else { // grab the x-y pos.s if browser is NS, Safari, Firefox... from e [event]
tempX = e.pageX;
tempY = e.pageY;
}
// catch possible negative values in NS4
if (tempX < 0) {tempX = 0; }
if (tempY < 0) {tempY = 0; }

var X = tempX;
var Y = tempY;
position = [X , Y ];
//return the array
return position;
}
access values by position.X or position.Y

Event, KeyPress in IE and firefox and preventDefault or return false

var event = e || window.event;

WebRequest AND HttpWebRequest to get Image from Server

Get the Web respose if you want an HTTP content out put

HttpWebRequest request = (HttpWebRequest)WebRequest.Create(uri);
 

HttpWebResponse response = (HttpWebResponse)request.GetResponse();

Stream str = response.GetResponseStream();

response.Close();

For something else (Example an Image or a file stored in Server )use the Regular webRequest

WebRequest request = WebRequest.Create(uri);

using (WebResponse response = request.GetResponse())

{

using (Stream responseStream = response.GetResponseStream())

{

// then use the image.

str = responseStream;

}

}

Linq JOIN

//var o = from p in db.t1
// join p2 in db.t2 on new { f1 = p.c1, f2 = “n” } equals new { f1 = p2.c2, f2 = p2.c3 } into temp
// from x in temp.DefaultIfEmpty()
// select new { f1 = p.c1, f2 = x.c2, f3 = x.c3 };

//var q = from ps in dcPeopleStatus.GetAll()
// join kd in dcKeyDetail.GetAll() on ps.pesStatus equals kd.Intern into kdTmp
// from x in kdTmp
// where x.RefValue.Equals(stat)
// select ps;

var q = from ps in PeopleStatus
join kd in dcKeyDetail.GetAll() on new { k1 = ps.pesStatus, k2 = keyId }
// equivalent to ps.pesStatus = kd.Intern AND kd.RefValue = keyId in SQL
equals new { k1 = kd.Intern, k2 = kd.RefValue }
where ps.pesRefPeople == peopleId && ps.pesIsCurrent == true
select new { ps.pesLocation, ps.pesStart, ps.pesStop, kd.ValueEn, kd.ValueGe, kd.ValueFr };

SQL Update and JOIN

UPDATE D
set D.feed_id = S.feed_id
from DEST D, Source S
where D.feed_id = 0
and S.invc_item_id = D.invc_item_id
and S.feed_id > 0
