1. ## Looking for a string policy search API

That's what I figured I'd have to use. I was put off from them because I had to use one in another project I worked on and I had no idea exactly how it worked. I guess I'll have to take the time to learn about them. Thanks!
2. ## Looking for a string policy search API

I'm looking for an API that would allow you to search strings for certain policies. For example, I would want to return strings that have a number pattern of a social security number, xxx-xx-xxxx, or maybe just a keyword(s) search. It would be nice to combine multiple policy searches into one search. Does an API like this exist out there free or paid? Preferably in C#? And if not, could you recommend where I should start looking to implement something like this myself?   Thanks!
3. ## Vector Rotation Problem

Any help guys? I don't understand the orientation matrix. I looked up the perpdot product and apparently it returns a scalar. How do you stick a vector d' and a scalar p into a matrix? !

Probably need to put the .dll's you're using into the same directory as your exe
5. ## Vector Rotation Problem

It is usually not necessary to compute an angle and from that to compute an orientation. Often it is suitable to build the orientation directly from the direction. E.g. if t denotes the target point and a the anchor point of the character, then d := t - a denotes the difference vector from the character to the target, and d' := d / |d| denotes the belonging normalized direction vector. Using the perpDot operator you can get a perpendicular vector to that. E.g. p := perpDot( d' ) = [ d'[sub]y[/sub] -d'[sub]x[/sub] ][sup]t[/sup] is a solution if the positive y is 90° counterclockwise to the positive x axis. With this, the orientation matrix is simply [ d' p ] (assuming that the "forward" vector is located at the first column). Much easier than using angles, isn't it? [/quote] I hate to ask, but would you mind giving a code example of this? Also, I don't understand what the perpendicular dot operator is. >_<

Thanks for your reply! I'll look through all of this tomorrow after work

8. ## unreal development kit

Click File->New, then click inside the perspective viewport (the one that shows a world full of black), click the red builder brush (the red box), hit space twice to switch to scaling mode, drag one of the cubes to change the size of the brush, and then click the top left button under CSG on the left toolbar (CSG Add).
9. ## Calculus Help!

It's not meant to be mathematically true, it's meant to be a fun brain teaser .
10. ## Calculus Help!

Anyway, here's what I got for your problems. 1. Simplify (1/x - 1/x)/(x - 2) to (2-x)/(2x^2 - 4x). Next, factor a -1 out of the numerator and a 2x out of the denominator resulting in [-(x - 2)]/[2x(x - 2)]. This simplifies to -1/2x. The limit of -1/2x as x approaches 2 is -1/4. 2. First, multiply out (4 + h)^3. This results in h^3 + 12h^2 + 48h + 64. Which, in the whole problem results in (h^3 + 12h^2 + 48h + 64 - 64)/h. This of course simplifies to h^2 + 12h + 48. The limit of h^2 + 12h + 48 as h approaches 0 is 48. For those that are curious, these answers check out using L'Hopital's rule. Kubapl, if you have any questions, feel free to ask.
11. ## Calculus Help!

L'Hopital's rule is soooo convenient isn't it? However, there's a problem. I assume that he/she is taking Calculus 1, and limits are done a week or two before derivatives. If he/she does not know how to take a derivative of a function, he/she certainly cannot do L'Hopital's rule . Also, most teacher's don't really like L'Hopital's rule to be used (except when they're teaching it) when other methods are possible because it hides what's really going on.

Thank you.
13. ## Visual Studio 2005 Annoying Problem

Somehow I turned on a feature in Visual Studio 2005 where, for instance, it shows arrows on every indention, and little *'s in every space. How do I turn this off? Thanks.
14. ## Classes, Header Files, and SDL - Help!!!

0 errors! Thanks for the help.
15. ## Classes, Header Files, and SDL - Help!!!

Quote:Original post by Juanxo hey again: I have found the error. You cannot create structs like you are doing in your constructor ( {255,255,255}) Also, in your constructor implementation, you need to use std::string, instead of just string Woot, your first solution cut it down to 47 errors! Let me see if I can wade through these and get it working. I'll be back if I can't figure it out. The std::string thing was an isolated error, I have std::string in all other files where it's used. >_<
