can anyone provide me with good links Visual Basic tutorials ? thanks in advance

question as above.........more over, it is about setting up DNS server.. Albert

How many times does the print statement execute? for i[1] = 1 to n do for i[2] = 1 to min(i[1], n - 1) do for i[3] = 1 to min(i[2], n - 2) do . . for i[n - 1] = 1 to min(i[n - 2], 2) do for i[n] = 1 to 1 do print i[1], i[2], ..., i[n] I get a headache just from looking at it...

I need to highlight the background of some text, but I don't know the code! HELP!!!!

Does anyone know anything about W32.Beagle.AC@mm. Norton keeps finding it but can't fix it and every few minutes it pops up saying so. I tried deleting the file it says the problem is in, but it just comes right back. So we now have a premanent Norton window saying "you're computer is infected and you can't fix it. Hahahahaha."

You always seem to be defending windoze...

I was reading through my parallel comp. book when I came across this sentence: If the bisection bandwidth of a network is w, the lower bound on the area in a two-dimensial packaging is Θ(w2), and the lower bound on the volume in a three-dimensional packaging is Θ(w3/2). This is where I stopped since I have no idea how and where they got these lower bounds from. Anybody here familiar with this? Maybe I should just stop reading this weird book.

Weird. I keep seeing favicons on tabs, seemingly at random. Sometimes it's an "S", sometimes a "B". I know these are not part of the site, because they sometimes appear on domains I control. Anyone know what they are? Are they a feature of some extension I didn't bother to read the documentation for?

I was looking around to find something to do over the summer, when I came across the idea of learning how to do computer animations. I saw two classes, one for Flash and one for "Basic Director." I'd like to know which you think is better, and what each does over the other. Thanks in advance!

I have a dynamic IP address, and is there any free DNS server software that automatically change the IP of domain name, so I dont have to change it my self every time I re start my computer? Albert

I hope this isn't to over-the-top for this forum. I have some comments on the following example from a book of mine on parallel computing: Consider a computation running on a machine with a 1 GHz clock, 4-word cache line, single cycle accesss to the cache, and 100 ns latency to DRAM. The computation has a cache hit ration of 1 KB of 25% and 32 KB of 90%. Consider two cases: first, a single threaded execution in which the entire cache is available to the serial context, and second, a multithreaded execution with 32 threads where each thread has a cache residency of 1 KB. If the computation makes one data request in every cycle of 1 ns, in the first case the bandwi…

Hi, I'm confused there! ADSL and N-ISDN use extra frequency bands for more capacity, right? BUT, they are still analogue like dial-up? Am I right? David

Can anyone tell me if there is a simple way to open a program but not have it show up on the stutus bar (or whatever it is called) in XP.

Most open source softwares are designed under Linux/Unix system... and some of them are being compiledin on Windows so it makes it compatible with..... but it is only the majority of Linux/Unix users using the Open Source softwares in tendancy, that even the OS itself is open.... What I want to ask is: Is there a tendancy that Mancintosh uses Open Source softwares, and any thing on Open Source development? Albert

I have just installed FreeBSD on my laptop....... and when I insert my PCMCIA network card after reboot, it shows this message: card bus 0: <network> at device 0.0 (no driver attached) vbb0: cardbus card activation failed I have search on the Internet for this, and people say there is NetBSD, which runs on just everything, but does that mean every platform, or every hardware? Secondly, is it possible to make a driver ourselves for FreeBSD? Albert

I have recently experienced problems between my Hewlett Packard psc 750 printer-scanner-copier and Microsoft Word XP. Whenever I print a document through File menu and print 1 copy, several (eg. 36 copies) are printed. I have looked at HP's site and Microsoft's site and can find no help on this subject. Have you had this problem? I really need answers. I am wasting a lot of paper and ink with thsi issue.

I think this problem is better explained by Mandrake users.... Buffer I/O error on device hdc Media error Above is the message while I am installing Mandrake v10 It takes a long time on repeating this message, and finally Mandrake cannot recover this... Any help? Albert

Does any one know about Neural Networks and their current applications in the research field

I have searched on the Internet and see that BBC has media News, but those are too short, like only seconds!!! Does any one know where to see various kinds of Media News freely? like the whole match of Euro Cup 2004 Greece vs Portugal for example..... Albert

I am not meaning multi-window appz. i mean real multitasking... how does the OS manage to let the programs have the control of the machine; having them all active; and pushin and poping the values of the pointers (ip,di,si...) from the stack, and manage to regain control when one of those programs get frozen...
