Hello,
I'm a newbie in computer programming.
I'm looking for a program help me to change file attributes(Created time,Modified time and last access) like FileDate By T.YogaRamanan.
Here is link :
http://www.codeproject.com/file/FileDate.asp[^]
But I want to ignore its user interface.(No Dialog box , No Text box)
I want to choose file as coding and change file attribute as coding too.
I have tried to read source code of FileDate above.
I still can't do.
Can you help me ? 
Thank you.

This is not the right forum for your question. And dont re-post same topics all over the place.

Hi guys,
I 'm a student of computer science from Indonesia
and newbie in vb6 programming. please, help me to
learn the algorithm of vb6. the following is algorithm
question.
1) Present the prime number between 1 up to 10 that use
"Mod" and "Print" function. the Object is only 1 command
button.
Note: forbidden use "int" function
thank's for helping me.
your sincerely
IRWAN

Which part don't you understand? Ask a specific question, otherwise people here aren't going to do your homework for you.

Lately it seems like most of them come from third world countries where the powers that be want to ship US jobs. They're too lazy to even try to do their homework and they get rewarded for it.

Maybe so on this site... have you recently checked Rent A Coder? I see a lot of US students posting homework questions there...

Are you sure they really are in the US? Could be somewheres else in the world and making it look like they are in the US...

Have you actually looked for yourself?

They can go ahead and do so. Any company that feeds these people will be in for a rude awakening when they find out their IT staff is so incompetent they leech off of people like us.

It is sad to read this kind of statements here. Helping each other is the main purpose of these forums. Not comparing IT staffs

well, looks like no one here will help with the homework...
try this
private sub Commad1_click()
dim i as integer
for i=2 to 10 'why 2 cos 1 is not prime number
if i mod 2 =0 then debug.print i
next i
end sub
selamat berjuang....

Because most of us here don't do people's homework for them. Your code does not work 100%.

ups my mistake, the code suppose to be something like this, sorry.. sorry..
for i=2 to 10
if i mod 2<>0 then debug.print i
next i

Hi I have spent the day looking at implementing RSA on the client side with javascript and on the server side with C#.NET.
I think I am overlooking something very simple and this is my problem. To make a key of 1024 bits requires a datatype to store it in. What datatype should i use, i considered byte[] but surely byte[]*byte[] is undefined (to create the key).
Any help will be greatly appreciated
Thanks
Dan

You need to find a library for integers of arbitrary length or write one yourself.
Cheers,
Sebastian

Write or find the class that will handel the 1024(or biger) bit long number.
if write see some algoritms like:
1) Baret reduction
2) Montgomeri multiplay
. . . .
you will ned them in class.
[ It will better if you write class]

My new project, I'm working on some path-finding algorithms for little AI
people. I have a grid of terrain heights and I have a pathing algorithm. The
trouble I'm having is how to weight the movement cost from one square to the
next. If moving across level terrain from one square to another is 1, how do
I cost uphill and downhill travel? I'm kinda stumped.
Also, moving diagonally is technically 1.41 in distance, should I cost it as such or just leave it as one for simplicity's sake? What are the pros and cons?
Any thoughts?

I think you should leave it as 1.41, otherwise you'll have funny results 
Regarding height, maybe a cost formula like sqrt(deltaX^2 + deltaY^2 + (k*deltaZ)^2) might do
You could change the k coeff if climbing is more or less expensive than moving horizontally.

Wow. It never occured to me that the Pythagoreum thing worked in three dimensions. Thanks. That helps a lot.
My question is though, what to change the value of k to? If the target square is n higher or n lower, how do you cost it for the expense of climbing uphill, or downhill as compared to walking over level ground? I thought about giving it an arbitrary value based on the difference in terrain heights, but that seemed kinda clunky to me.
What I should do I suppose is find a chart on the internet of the amount of calories burned in walking as opposed to stair-climbing and wall-climbing. That might help.
Thanks again.
----------------------
...ten minutes later
Okay, I looked up the calorie charts and it turns out that stair-climbing is approximately double straight walking, and wall-climbing is approximate triple straight walking. So if I convert that to angles:
0 = 1
45 = 2
90 = 3
Now how do I convert that into a formula so that values in between return their appropriate costs?
I'll assume the values are the same for going down in terrain as well, though they might be slightly cheaper.

cost = 1 + (angle / 45)
d'uh. I better get some coffee. Thanks all.

I felt curious about the calories issue, i think it is a good idea of giving values to k I've found this link:
http://www.calorie-count.com/calories/activities/17.html

I figured it out. Thanks, kind sir.
k = 1 + (angle / 45)
Now to figure out how to calculate the angles...

Just remember your trig functions:
/|
h / |
/ | o
/ |
/ θ |
------
aI remember them with the mnemonic SOHCAHTOA:
SOH -> sin(θ ) = opposite / hypotenuse
CAH -> cos(θ ) = adjacent / hypotenuse
TOA -> tan(θ ) = opposite / adjacent
Then, to find the angle, you can use the inverse trig functions:
θ = asin(opposite / hypotenuse) = acos(adjacent / hypotenuse) = atan(opposite / adjacent)
In standard Cartesian coordinates, if the triangle is oriented as above with the origin located where θ is, then the adjacent side (a) is x, and the opposite side (o) is y. So, since you usually know x and y, there is no need to calculate the hypotenuse to find the angle, since you can then do θ = atan(y/x).
Be aware that the above identities are true only for radian angles. If you need degrees, then you must convert at the end using the identity 180 degrees = π (should be a pi, but it looks funny in my font) radians.

I kinda wish I took Trig. I suck.
Thanks anyway.
