Understanding the basics of algorithms and basic security applications. @ Articles -> Encryption May 28 2002 - 20:32 EST gregory_a_e writes: Simply put, this article is a brief overview of algorithms. What they are, how they tie into computers. By no means is this a technical article, nor an obscure tutorial of some sort, so if you're expecting to learn the specifics of cryptography and algorithms, I'm sorry to say you won't find it here. If you do become interested in the subject, I would suggest some reading material that is suitable. Applied Cryptography and Digi...

Trying to understand
Ok, I'm been trying to understand the new ADO.net thing, and it seems pretty simple, as long as your using databound controls.Unfortunatly, I have a lot of pages that I can just ad a grid view to and make the things look right, so I'm trying to understand how to programatically access ADO.net.Below is an example of some of the simplest code I need to convert and any help would be aprreciated.set connectionToDatabase=server.createobject("adodb.connection")connectionToDatabase.connectiontimeout=60connectionToDatabase.open "DSN=ServiceCalls"set rc=server.CreateObject...

Basic understanding
Hi all, trying to get a basic understanding. I have a few home pcs that connect to a wireless router which is in turn attached to a Cable modem and thence the Internet. I am told that the wireless router acts as a hardware firewall. However it fails Leaktest. In fact when I run Leaktest I am not prompted as expected to answer yes or no to any request for permission for access to the Internet (as the documentation suggests I should expect) , but it just goes right ahead and fails the test. Q: Is this expected behaviour, given that I am not running any other software-based...

Trying to understand...
Someone just hit me over 70 times inside 3 minutes on TCP ports over 63700 from 200.192.240.8. I dropped my connection and picked up a new IP, but is there really anything other than an attempt to invade my box that this kind of activity could be?

Trying to understand TStringDynArray
I've been away from programming a while. While coding a simple project, I've come across TStringDynArray. The below code snippet I've entered magically works (I'm using XE4), no errors, no warnings, no hints. In the (distant) past, I recall having to set the length of a dynamic array. That's no longer needed? Am I creating some memory leak with the below code? No need to free up memory? Thanks, Bob Lincoln ================================================== procedure TForm1.btnZipFolderClick(Sender: TObject); var DirToZip: string; ZipLi...

Still trying to understand..
Hey fellow Linux users! Let me introduce myself to all of you, my name is Ben and I'm a recent Suse 11.0 installer/user/novice. Let me start by saying Linux is so amazing. I love the interface and its super stable and quick. I'd choose this over windows anyday! I recently got a little interested in linux about 3 years ago when one of my Compute teachers gave me a Live Knoppix Cd. And I thought it was the coolest thing ever. But I still have a little dificulty understanding how linux works. I mean I read alot of websites and everything but its still a little confusing to me....

Trying to understand NPS
I am running a Novell SBS 6.0 SP4 server with NDPS running. From the books I have been reading, NDPS printers should show up in the NWADMIN list. I have no printers, I have the broker and manager objects. I can see the printers using the TOOLS -> Public Access NDPS printers under NWADMIN. Is there something I am doing wrong? Just wondering, Ken@rlmrlm.com No, this is correct. Public Access printers are viewed in this fashion. You may be looking for Controlled Access printers which will show up in NWAdmin under the context they are created. <ken@rlmrlm.com> wro...

Trying to understand backup
I'm trying to figure out how a database backup works. Suppose I back up the database and transaction log, and truncate the log. The next day I back up just the log. A couple of days later I want to restore to the second backed-up version. I restore the first backup database and log, then run the engine with '-a' to apply changes from the second log. First, is that the correct procedure? Second, did I really need the first backup log to do that? In other words, if I back up a database and truncate the log, is there anything in the pre-truncate log that I need to rest...

Trying to understand the stylesheet
If we give so many font names in the style sheet, which font is taken into consideration. Could any one explain me what this means. .Default { font-size:12px; font-family: Verdana, Arial, Helvetica, Geneva, Swiss, SunSans-Regular; } The font-family declaration is a list of "preferred" fonts, listed in order of preference. If the visitor's computer has Verdana installed, then Verdana will be the font used to render the page. If the visitor's computer does not have Verdana installed but has Arial installed, then Arial will be the font used to render the page. If the visitor's comp...

Trying to understand FormsAuthentication
First off, I'd like to note what a great resource this site is.  I've enjoyed browsing through it during my endevors of getting a handle on ASP2.0That being said, I'm working on setting up Forms Authentication on my site.  I'm a bit confused though.  Here's my setup:  I have certian parts of this site I'd like to have open to the public, no authentication necessary.  The option to login is always  going to be in my Master page as a custom form I created that authenticates with a sql database (this is functional).  As of right now authentication just redirec...
