Seems you are building some kind of CMS (Content Management System), anyway in such cases where you store too much paragraphs and they are localized I think you should go toward database. If you designed the app very well and took in consideration all minor details trust me performance will eliminate it self on the spot. having Xml is something horrible for large texts that you will have to live with through the development and maintenance life cycles of the your app.

Hi there,
Why would you use the ProviderUserKey property to get the user name ?! you can simply use the UserName property to get it.
And try making sure which object is null ? is it the returned MembershipUser object or the ProviderUserKey, my guess is ProviderUserKey.

Hi,
I am either looking for a Javascript function, or a regular expression that I can use in Javascript. I have been struggling to get mine to work, so I am asking if someone can please help me write a function.
What it must do is to allow only 3 decimal places. While I type the textbox must be validated. Something like 123.456 is valid. It should not allow anything after .456 It must accept a number or a float.
It must also allow a - and a +.
This is what I currently have (but it accepts lots of decimals):
var regex = /^(\d|-)*\.?\d*$/;
Please can someone help?
Thanks
Brendan

Hi Brendan,
This might help:
^[-+]?[0-9]\d{0,2}(\.\d{1,3})?$ - this will allow numbers like 1, -1.1, 123.456 but not 1234.234, 123.4567 or 1234.4567.
^[-+]?[0-9]\d{2}(\.\d{3})?$ - this will only allow numbers like 123.456 or -123.246.
I hope this helps.

Thanks Ryan, I will check it out soon. Just another question:
RyanMorris wrote:
but not 1234.234, 123.4567 or 1234.4567.
What's wrong with 1234.234?
You don't by any chance have some formatting script that when the textbox looses its focus that it formats the numbers to something like 1234.560 even if 1234.56 was typed in? I want it to be formatted to 3 digits. 123 becomes 123.000, 123.4 becomes 123.400 etc.
Does the above regular expressions accept only digits?

Sorry, I think I slightly misunderstood your question, I thought you wanted 3 digits each side of the decimal place. If that's not the case then you might want to try this instead:
^[-+]?\d+(\.\d{3})?$ - this will allow you to have as many numbers as you like in front of the decimal place but only 3 after it.
To be honest I wouldn't have a clue how to reformat the number after losing focus on the text box, my javascript isn't very good. Sorry.
All the expressions I've given you only except numbers.
Thanks,
Ryan

Hi,
I have a frameset based site I am modifying for a friend.
In one of the frames, in an block, I have an onClick handler assigned like so :
onClick= "window.parent.forumButtonClicked();"
In IE7/8 this works fine : I click on the image in the frame and it calls the function defined in the "master" page (index.htm).
But in Safari Beta 4, this does work. I have debugging enabled in Safari, but get no error message.
Ideas ? Is using "window.parent" not strictly W3c compliant here ?
I assume I'm going to have use some other way of referring to the enclosing master page ?
thanks !

This is the html file.
function beg()<br />
{<br />
var toggle ='on'<br />
var obj = document.getElementById('test')<br />
<br />
EC();<br />
<br />
<br />

{<br />
obj.src= "images/tbl_expand.gif";<br />
toogle = 'on';<br />
}<br />
}<br />
<br />
<br />
<br />
And this is the javascript file. What I need right now is when you click on the image. It toggles to the next image. Later on will be a drop down menu, something like show/hide. An example of this is on the website http://blog.movalog.com/a/javascript-toggle-visibility/[^

one other thing is that is has to be on the same page so its not going from page to page.
|
|
|
|
|
Try this:
function beg()
{
var obj = document.getElementById('test')
if(obj.src == "images/tbl_expand.gif")
{
obj.src = "images/tbl_collapse.gif";
}
else
{
obj.src = "images/tbl_expand.gif";
}
}

Please, you need to get a book on web development and start at page 1. You don't seem to know what html is or how it works, never mind the finer points of web development. I don't think you even understand what you are asking. If you are being paid for this work, come clean and say you lied about your ability, otherwise go and buy a book.

If you want code writing go to rentacoder.com or similar. Now, go buy a book............

Hi all,
This is senthil. I got a project(with codes and design) from my client to upgrade.
The project is mainly developed in vb.net (from the design pages i got this information).
In the project code-behind files are separated files.
But the project is not having these code-behind files. And the pages is also running without any failure in the server (with absence of these code-behind files). For upgrade purpose i opened the pages through vb.net IDE, But the code-behind files are not founded.
How this is possible.
Is anything i need to know.
I need these help urgently....
Note* - I didnt convert/migrate the project.
And the developed .Net IDE is VS 2005.
Thanks in advance

Did you check whether the inline code has been written inside the aspx itself or not?
Either you love IT or leave IT...

|

|

Thanks for your reply.
yes I Checked, But the vb.net code is writen in code behind file. Not in inline code.

Try to find the code-behind file specified in the page directive. If the page is using any code-behind then it must have been specified over there.
Either you love IT or leave IT...

To execute a simple NVP Operation to paypal such as:
<br />
https:
&cmd=_express-checkout&token=tokenValue<br />
&AMT=amount<br />
&CURRENCYCODE=currencyID<br />
&RETURNURL=return_url<br />
&CANCELURL=cancel_url<br />
Should I initiate an AJAX request? It is stated in REF doc below that:
<br />
Executing NVP API Operations<br />
You execute an PayPal NVP API operation by submitting an HTTP POST request to a PayPal<br />
API server.<br />
...<br />
Interpret the Response<br />
PayPal processes your request and posts back a reponse in NVP format. Add code to your web<br />
application to do the following tasks:<br />
1. Receive the HTTP post response, and extract the NVP string.<br />
2. URL-decode the parameter values as described in "URL-Encoding" on page 14.<br />
3. Take appropriate action for successful and failed reponses.<br />
For instance:
<br />
REF: http:
<br />
<html><br />
<body><br />
<script type="text/javascript"><br />
function SubmitOrderToPaypal()<br />
{<br />
var xmlhttp;<br />
var strUrl;<br />
<br />
strCmd = "https://www.sandbox.paypal.com/webscr&cmd=_express-checkout&token=tokenValue&AMT=amount<br />
&CURRENCYCODE=currencyID&RETURNURL=return_url&CANCELURL=cancel_url";<br />
<br />
if (window.XMLHttpRequest)<br />
{<br />
xmlhttp=new XMLHttpRequest();<br />
}<br />
else if (window.ActiveXObject)<br />
{<br />
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");<br />
}<br />
else<br />
{<br />
alert("Your browser does not support XMLHTTP!");<br />
}<br />
xmlhttp.onreadystatechange=function()<br />
{<br />
if(xmlhttp.readyState==4)<br />
{<br />
document.myForm.time.value=xmlhttp.responseText;<br />
}<br />
}<br />
xmlhttp.open("POST",strURL,true);<br />
xmlhttp.onreadystatechange=handleResponse;<br />
xmlhttp.send(null);<br />
}<br />
<br />
function handleResponse()<br />
{<br />
if (xmlhttp.readyState==4)<br />
{<br />
document.getElementById("txtPaypalResponse").innerHTML=xmlhttp.responseText;<br />
}<br />
}<br />
</script><br />
<br />
<form name="myForm"><br />
<input type="image" name="submit" onclick="SubmitOrderToPaypal();" border="0"<br />
src="https://www.paypal.com/en_US/i/btn/btn_buynow_**.gif"<br />
alt="PayPal - The safer, easier way to pay online"><br />
</form><br />
</body><br />
</html><br />
And now, how can I retrieve response from PayPal?
Many thanks
