I want to prevent users from entering an existing code in my database.
I have a middle tier that checks and return whether a Code exists or not.
Which validation control do i need to tell user that the code they
entered is already existing

Use the CustomValidator control. Then you need to write code for its ServerValidate event
You write something like
ars.IsValid = IsValidCode(args.Value)
where IsValidCode() is a function for you to implement, which it looks like you already have from your middle tier.
Then in your Submit or OK button click event
If Page.IsValid Then
...
End If

can anyone give me the approach to download a file from a ftp server using multithreding. (i.e. separate threads for downloading simultaneously USING JAVA)

Hi, I dont use java... but... what you need to do is incorporate your pasv port process inside a thread.. i dont know for sure about the rest.. they may or may not have to be in a thread...
|
|
|
|
|
sorry pasv port is ftp socket.... basically just the socket which connects must be in a thread and possibly even the file write process...

How Can I assign the js variable to php variable?
Programistebo saqartvelosi sheertdit

You have to pass a variable to a server side script (PHP) using one of the following methods:
1) GET
2) POST
3) Cookie
HTML FORM's are typically sent using POST (as the amount of data you are allowed to submit is likely virtually infinite) however if you have a variables passed in Javascript, you will likely want to use GET.
var jscript_var = "Some value";<br />
<br />
location.href="index.php?jscript_var="+jscript_var;
YYou could also use cookie or post, but POST would be awkward without AJAX and Cookies are more permanent...
The above code shows you how to pass a variable though 
HTH

In .Net 2.0 you have a login control. You may develop a page to change the password.

Shared DLL assembly that will be used by 100's of web apps.
What is the best way to deploy this shared assembly, considering the shared assembly version is not fixed... it is still in ongoing development and may need to be updated once per month with new functionality.
GAC? this would mean regression testing the dependent apps(100's) for each new version.
/bin folder? this would mean multiple versions of the shared assembly in use at any 1 time.
Any other methods?
What deployment method is best?
thanks.

Hi all,
I have a very weird problem:
I have a web page (myfeeder.asp) to generate very simple xml content. I use ie to navigate to the page, I can see the xml content on MOST of the pc. the xml like:
<?xml version="1.0"?>
<ads>
<ad>
content here.
</ad>
</ads>
My problem is, I CAN NOT get the xml content from some of web server's IE. what I got is nothing or just the structure, like below. It also happpends to some linux server.
<?xml version="1.0"?>
<ads>
<ad>
</ad>
</ads>
I know the server/pc that can not get the xml content is using re-writing.
I have no idea what cause the problem!!
Does any one have the same experience!!! Please help me to solve the problem!!!!
Thanks in advance!!

Hi, folks!
I'm building a table of data, retrieved from a database. One of the fields is boolean and I want to set/unset a checkbox in my table depending upon the value in the data table (which is of type bit).
Here's what I have so far...
<br />
oCell = oRow.insertCell();<br />
oCell.align = "center";<br />
oCell.style.fontSize = "12";<br />
oCell.style.fontWeight = "normal";<br />
oCell.style.border = "thin black solid";<br />
sTag = "<INPUT type='checkbox' id='cb" + i++ + "'>";<br />
aElement = document.createElement (sTag);<br />
aElement.checked = Rs("AllowEmail");<br />
oCell.appendChild(aElement);<br />
but this does not work. I get the checkboxes ok, but I can't set them, even if I explicitly say aElement.checked = true; So, how do I access the checked property?
TIA!!
'til next we type...
HAVE FUN!! -- Jesse

Hmmm, seems like that should work, but.....have you tried:
<code>
sTag = "<INPUT type='checkbox' id='cb" + i++ + "'";
if (Rs("AllowEmail"))
sTag += " checked";
sTag += ">";
aElement = document.createElement (sTag);
oCell.appendChild(aElement);
</code>
