Alphanumeric characters only.<br />
Must have at least 4 numeric characters.<br />
Must have no more than 2 alphabetic characters.<br />
The third and fourth characters must be numeric.

Sounds like a regular expression to me.

Yeah, it COULD be any of those things, but I imagine that a regex is the most logical. expresso is a great tool if you need help working out a regex.

Hi Vasudevan Deepak Kumar,

Thanks for response. I have "Expresso". I have tried this. But I can't figure out the correct expression. I can't make expression with numeric and alphabetic. somewhere I am wrong. I am still playing with "Expresso"..... Confused | :confused:

U can try out for Javascript posted below
Expresso cannot work for the expressions like this. That becomes tough for Expresso.

Try this.. put the code in ur jscript

<br />
function nx(obj)<br />
{<br />
	var str = document.getElementById(obj).value;<br />
	if(str.length > 3 && str.length < 10)<br />
	{<br />
		if((str.charCodeAt(2) > 47 && str.charCodeAt(2) < 58) && (str.charCodeAt(3) > 47 && str.charCodeAt(3) < 58)) <br />
		{<br />
				var c = 0;<br />
				var n = 0;<br />
				for(i = 0 ; i < str.length ; i++)<br />
				{<br />
					if(str.charCodeAt(i) > 47 && str.charCodeAt(i) < 58)<br />
					{<br />
						n++<br />
					}<br />
					else<br />
					{<br />
						c++<br />
					}<br />
				}<br />
				if(n < 4 && c > 2)<br />
				{<br />
					return false<br />
				}<br />
				else<br />
				{<br />
					return true;<br />
				}<br />
		}<br />
		else<br />
		{<br />
			return false;<br />
		}<br />
	}<br />
	else<br />
	{<br />
		return false;<br />
	}<br />
	return false;<br />
}<br />

The ASCII part is very Improtent to do the task.
I hope that will help
If work let me know. Smile | :)

I have a directory 'UploadFiles' in my website, and I can forbidden users to visit via *.ASPX page.
(check users right in *.aspx.cs), but i can not forbidden user to visit via directly input URL in browser. like http://localhost/mywebiste/uploadfiles.jpg

I know the MembershipProvider in .NET Framework, but i think it too complex than i wanted.
and i didn't find any document to help me write a good web.config file.
so how can i solve it?

I prefer to write a HTTPHandler which handles JPG extension. Inside the handler, do user authorizations. If user is unauthorized, display relevant messages.

thanks for your reply.
the JPG files just a kind of 'UploadFiles', it contains many different file types, like bmp, txt, doc, xls, mp3, avi, and so on.
i do not want to add a HTTPHander for all file types.... Sigh | :sigh:

Are you getting this error when you refer it ? What this COM control is doing ?

Why do you need to use a com component on the server side ? Have you tried taking your code out of the ASP.NET code behind and put it in a windows app to see if that works ? Have you looked up the error code to see what it means ?

It's bad idea to block the keys. You might be able to do this with JS, but it's not reliable. Why you need to block users opening pages in new window ?

Some of the financial applications expect this sort of weird behavior.You need to have yeoman patience and skillset to convince those dumb managers.

Yes. But a better approach would be the following.

1 - When user opens the page, we set a flag in DB
2 - Page load, this flag is checked to ensure only one page is running.
3 - When user finishes the operation, reset the flag.
4 - A scheduled job should run frequently which checks the flag value and the time it has started. if it is more than timeout limit, reset the flag.

What do you think ?

You may need to entrap the keycode for CTRL+N in keydown event and NULL it.
