Javascript: Proper case validation

I am just posting a Javascript sample which I created for answering a question in dotnetspider.

<html>
<head>
<title>Proper Case Validation -- Sample by Vadivel</title>
<script>
<!--

function ConvertToProperCase()
{
strTemp = document.form1.txtString.value
strTemp = strTemp.toLowerCase()

var test=""
var isFirstCharOfWord = 1

for (var intCount = 0; intCount < strTemp.length; intCount++)
{

var temp = strTemp.charAt(intCount)
if (isFirstCharOfWord == 1)
{
temp = temp.toUpperCase()
}

test = test + temp
if (temp == " ")
{
isFirstCharOfWord = 1
}
else isFirstCharOfWord = 0
}
document.form1.txtString.value = test
}
// -->
</script>
</head>

<body>

<form name=form1>
<input size=50 name=txtString>
<input type=button onClick=ConvertToProperCase() value="Convert It Now">
</form>

</body>
</html>

Update: I have tested it with IE 6.0 alone. May be for working in other browsers you need to do little bit of tweaking. For ex: need to put semi-colons at the end of each statements.

After verifying javascript with javascript verifier i found no. of errors... even i would suggest you to run the same page with firefox and you find the same... so after removing error with jslint.com i found the valid equivalent javascript as under:

function ConvertToProperCase()
{
strTemp = document.form1.txtString.value;
strTemp = strTemp.toLowerCase();

var test="";
var isFirstCharOfWord = 1;

for (var intCount = 0; intCount < strTemp.length; intCount++)
{

var temp = strTemp.charAt(intCount);
if (isFirstCharOfWord == 1)
{
temp = temp.toUpperCase();
}

test = test + temp;
if (temp == " ")
{
isFirstCharOfWord = 1;
}
else
{
isFirstCharOfWord = 0;
}
}
document.form1.txtString.value = test;
}

How do you make it so certain words in a string are not affected by the function?

Registry manipulation from SQL

Registry Manupulation from SQL Server is pretty easy. There are 4 extended stored procedure in SQL Server 2000 for the purpose of manupulating the server registry. They are: 1) xp_regwrite 2) xp_regread 3) xp_regdeletekey 4) xp_regdeletevalue Let us see each one of them in detail! About xp_regwrite This extended stored procedure helps us to create data item in the (server’s) registry and we could also create a new key. Usage: We must specify the root key with the @rootkey parameter and an individual key with the @key parameter. Please note that if the key doesn’t exist (without any warnnig) it would be created in the registry. The @value_name parameter designates the data item and the @type the type of the data item. Valid data item types include REG_SZ and REG_DWORD . The last parameter is the @value parameter, which assigns a value to the data item. Let us now see an example which would add a new key called " TestKey ", and a new data item under it called TestKeyValue :

Screen scraping using XmlHttp and Vbscript ...

I wrote a small program for screen scraping any sites using XmlHttp object and VBScript. I know I haven't done any rocket science :) still I thought of sharing the code with you all. XmlHttp -- E x tensible M arkup L anguage H ypertext T ransfer P rotocol An advantage is that - the XmlHttp object queries the server and retrieve the latest information without reloading the page. Source code: < html > < head > < script language ="vbscript"> Dim objXmlHttp Set objXmlHttp = CreateObject("Msxml2.XMLHttp") Function ScreenScrapping() URL == "UR site URL comes here" objXmlHttp.Open "POST", url, False objXmlHttp.onreadystatechange = getref("HandleStateChange") objXmlHttp.Send End Function Function HandleStateChange() If (ObjXmlHttp.readyState = 4) Then msgbox "Screenscrapping completed .." divShowContent.innerHtml = objXmlHttp.responseText End If End Function </ script > < head > < body > &l

Script table as - ALTER TO is greyed out - SQL SERVER

One of my office colleague recently asked me why we are not able to generate ALTER Table script from SSMS. If we right click on the table and choose "Script Table As"  ALTER To option would be disabled or Greyed out. Is it a bug? No it isn't a bug. ALTER To is there to be used for generating modified script of Stored Procedure, Functions, Views, Triggers etc., and NOT for Tables. For generating ALTER Table script there is an work around. Right click on the table, choose "Modify" and enter into the design mode. Make what ever changes you want to make and WITHOUT saving it right click anywhere on the top half of the window (above Column properties) and choose "Generate Change Script". Please be advised that SQL Server would drop actually create a new table with modifications, move the data from the old table into it and then drop the old table. Sounds simple but assume you have a very large table for which you want to do this! Then it woul
