Get viewport size (width and height) with javascript

Source : http://andylangton.co.uk/articles/javascript/get-viewport-size-javascript/

<!–

var viewportwidth;
var viewportheight;

// the more standards compliant browsers (mozilla/netscape/opera/IE7) use window.innerWidth and window.innerHeight

if (typeof window.innerWidth != 'undefined')
{
viewportwidth = window.innerWidth,
viewportheight = window.innerHeight
}

// IE6 in standards compliant mode (i.e. with a valid doctype as the first line in the document)

else if (typeof document.documentElement != 'undefined'
&& typeof document.documentElement.clientWidth !=
'undefined' && document.documentElement.clientWidth != 0)
{
viewportwidth = document.documentElement.clientWidth,
viewportheight = document.documentElement.clientHeight
}

// older versions of IE

else
{
viewportwidth = document.getElementsByTagName('body')[0].clientWidth,
viewportheight = document.getElementsByTagName('body')[0].clientHeight
}
document.write('

Your viewport width is ‘+viewportwidth+’x'+viewportheight+’

How to Perform SQL Server Row-by-Row Operations Without Cursors

Orignal Post: http://www.sql-server-performance.com/articles/per/operations_no_cursors_p2.aspx

But i have modfiy the sql as below:

DECLARE @iNextRowId int,
@iCurrentRowId int,
@iLoopControl int,
@rowValue nvarchar(255)

– Initialize variables
SELECT @iLoopControl = 1
SELECT @iNextRowId = MIN(id) FROM #table

– Make sure the table has data.
IF ISNULL(@iNextRowId,0) != 0
BEGIN

– start the main processing loop.
PRINT ‘START’
WHILE @iLoopControl = 1
BEGIN
— This is where you perform your detailed row-by-row
— processing.
— Reset looping variables.

SELECT @iCurrentRowId = id, @rowValue = value FROM #table WHERE id = @iNextRowId
PRINT @rowValue + ‘ (ID: ‘ + CAST(@iCurrentRowId as varchar(1000)) +’, Next Row ID: ‘+ CAST(@iNextRowId as varchar(1000)) +’)’

–SELECT @iNextRowId = NULL
– Get the next iRowId
SELECT @iNextRowId = MIN(id) FROM #table WHERE id > @iCurrentRowId

IF ISNULL(@iNextRowId,0) = 0
BREAK;

END –END WHILE LOOP
END –END Check table has data

讓Browser的「上一頁」無效（網頁已過期）

Response.Cache.SetCacheability(HttpCacheability.NoCache);

先了解一下Brower「上一頁」的原理，
Browser「上一頁」是一種Cache機制，將WebPage暫存在Browser端，以省下loading的時間。
若只是瀏覽Web，「上一頁」機制是很讚的。可處理敏感性資料就頭痛了。

解法就是把該Cache關掉就行了。

Regex match html content without screwing up the tags

private string replaceString = “”;
public string Parse(string content)
{
const string regTagName = @”<.[^>]*>”;

Regex reg = new Regex(@”(” + regTagName + “)|(geekzilla)”,

// this is what I’d like to replace the match with
replaceString = “$1“;

// do the replace
content = reg.Replace(content, new MatchEvaluator(MatchEval));

return content;
}

protected string MatchEval(Match match)
{
if (match.Groups[1].Success)
{
// the tag
return match.ToString();
