very unlikely. You'd need a lossless compression routine to do that, but a cryptographic hash should be essentially random and largely incompressible as a result.

Not gonna happen. SHA256 encodes in blocks of 256 bits (or 32 bytes) so that is the smallest output you will get. If you want the string to be reversible then your output will be of comparable size to the input string (it will be rounded up to the next block boundary)

Hi to all,

I am developing a web application on ASP.Net using C#. In this i have used one listbox for containing list of files. Whenever i select the item from this list box i want to display the details of that file from the database, so for that purpose i used ListBox1.SelectedIndexChanged event to perform this task. but at the runtime when i select item from the listbox this event does not occurs, it occurs at the PageLoad event.

Anybody can tell me how can i remove this problem.

you should check for handles clause.
missing handles clause in event handler might be the reason

Hello experts,

I make a DLL named maths.DLL. In that I include all the possible
functions related to maths.

But what I see other user can add this DLL as a reference and use my functions... Frown | :-(

I want to make My DLL password protected so no one can import it and
use it.

How I can do that...?

Please help...

Cry | :((

Why don't you use obfuscater.Vs 2005 comes with one . you can use it to obfuscate your code so no one can use your class library

Thx for reply sir,

What i see the obfuscater is the third party component and we have to buy it.
I want to make security using .net. Is their any way to use .Net Securities ?
So I can make my DLL secure i.e no one use it or you can say password protected DLL Dead | X|

I want to search a file from server and want to copy it to the local disk.
how it is done? This is working if the file is in my hard disk itself.But not when it comes to server. If i map the server i can search.like y:\\serverfolde\\folder am tring to make an exe. different people will map to different drive. so i cant give like that.should give like @\\server\\serverfolde\\folder\\ but it is not working.
My code is

<br />
searchfolder="y:\\Template\\else";<br />
				destination ="D:\\Princy\\My Documents\\project\\";<br />
				string source=searchfolder+"\\"+"mod501_"+filetosearch+".3d";<br />
				string target=destination+"mod501-"+filetosearch+".3d";<br />
				string[] files = Directory.GetFiles(searchfolder, "mod501_"+filetosearch+".3d");<br />
				//string[] files = Directory.GetFiles(searchfolder, filetosearch+"*");<br />
				if(files.Length==1)<br />
				{<br />
					foreach (string dir in files) <br />
					{<br />
						lblcnt.Text="Selected File: "+ dir;<br />
						string[] search = Directory.GetFiles(destination,"mod501-"+filetosearch+".3d");<br />
						if(search.Length>0)<br />
						{<br />
							lblcnt.Visible=true;<br />
							lblcnt.Text="File already exist";<br />
						}<br />
						else<br />
						{<br />
							File.Copy(source,target);<br />
							lblcnt.Visible=true;<br />
							lblcnt.Text="File copied";<br />
						}<br />
					}<br />

what to give insted of
searchfolder="y:\\Template\\else";

If am using
searchfolder="@books\\template\\Template\\else";
am geting error:
System.IO.DirectoryNotFoundException:Could not find a part of the "@books\template\Template\els".
Otherwise its working perfectly.
