What Do You Need Help With? V6

[pyschomc]

The work I'm doing right now for java
For the first assignment [quote]Suppose you buy 100 shares of a stock at $12 per share, then another
100 at $10 per share, and then sell 150 shares at $15. You have to pay
taxes on the gain, but exactly what is the gain? In the United States,
the FIFO rule holds: You first sell all shares of the first batch for
a profit of $300, then 50 of the shares from the second batch, for a
profit of $250, yielding a total profit of $550. Write a program that
can make these calculations for arbitrary purchases and sales of
shares in a single company. The user enters commands buy quantity
price, sell quantity (which causes the gain to be displayed), and
quit. Keep a queue of objects of a class StockBlock that contains the
quantity and price of a block of shares. Do not break the block apart
into separate stocks. The example above should store 2 blocks, not
200. For the draft, your program should work for a single purchase
and sale. For both versions, you should use the Queue interface, and
you can assume integer prices. There will be no short-sale attempts.
(I will never try to sell more than I own.)[/quote]

[B]I have already written the draft and I got the it to buy one share, but now I have to buy 2 shares[/B]
How would I go with this?

How do i set a in game chat command so when people type !donate it opens their in game browser to a specified donation page? Please help, for TTT Gmod, with ULX admin mod

[Gulen]

Wrong forum buddy, [URL="http://facepunch.com/forumdisplay.php?f=65"]Garry's mod Developer Discussion[/URL] is what you're looking for.

[Insight]

I have

[img]http://puu.sh/2si2F[/img]

Basically it is a custom class in a DLL that has runs commands and makes it its own element inside of a winform, inheriting Label.

Basically instead of it drawing right there on the winform in the editor view, I am wanting so in place of all the stuff rendering is just a simple image stating that that box is an item that I created. Or not having anything drawn inside that custom element box.

How do I do a MySQL statement that selects rows ending in 'st' or 'rd'?

[QUOTE=SammySung;40127987]How do I do a MySQL statement that selects rows ending in 'st' or 'rd'?[/QUOTE]

Does this have to be pure sql?

SELECT * FROM herp WHERE derp LIKE '%st';

Like that?

[SammySung]

[QUOTE=eternalflamez;40128497]Does this have to be pure sql?[/QUOTE]

It's alright, I figured it out. And I'm not really sure, it's part of my uni course.

So I have query that looks like this

SELECT C.CITYNAME, W.CAPACITY
FROM CITY C
INNER JOIN WAREHOUSE W
ON C.CITYCODE = W.CITYCODE
WHERE W.CAPACITY >=10000

Which presents this: [img]http://puu.sh/2spff[/img]

How can I make it add up all the cities population respectively to arrive at each city being presented once?

For example, it would show Melbourne as 50,000 (20,000+30,000)

[mobrockers2]

[cpp]
SELECT DISTINCT(C.CITYNAME), W.CAPACITY
FROM CITY C
INNER JOIN WAREHOUSE W ON C.CITYCODE = W.CITYCODE
WHERE W.CAPACITY >=10000
[/cpp]

[QUOTE=mobrockers2;40128972][cpp]
SELECT DISTINCT(C.CITYNAME), W.CAPACITY

WHERE W.CAPACITY >=10000
[/cpp][/QUOTE]

I've tried that before, just tried it again to make sure it doesn't work. I get this:

Btw why are your database elements in uppercase?

I meant something like "Are you using php or something of the likes to achieve this, or just mysql"

I kinda thought he meant it like selecting rows that have names that end with 'st' or 'rd'.

Wouldn't you need to select SUM( W.CAPACITY ) ? If not could you explain why it works?

[mobrockers2]

I have an IDE problem...

    public partial class Form1 : Form
    {

        public Form1()
        {
            InitializeComponent();
        }

        private void Form1_Load(object sender, EventArgs e)
        {

        }
    }

So when I copy paste it's { and }, but in IDE it shows [ and ], and when I try to type { or } it transforms into [ and ]...

Might want to tell us which IDE perhaps?

Need some help with this rotation... I have 2 16x16 sprites, a player and a weapon, I am setting the weapons position and rotation to the same as the player, but I am not getting the expected result. This is what it looks like without rotation, but position ( correct ):

[IMG]http://i.imgur.com/I3pxBDR.png[/IMG]

this is what happens as I rotate around. I suspect it has something to do with the center of rotation but changing it didn't seem to do much.

maybe you should blit the player model and its weapon onto a seperate sprite and then just rotate and blit that

At first I was stumped why it happened in 2 different IDEs but then it hit me - the IDEs weren't broken, it was the font that was broken... Apparently something messed up Courier New font IDEs were using.

I haven't done this before, but you could take 3 points along the path, and add in points between the two outermost ones along a curve (spline? bezier?) that uses the middle point as the curve extent. Depending on how sharp the curve is, the result could either turn into an amorphous blob of green, or something that still resembles the original shape.

Gonna ask a question.

Where should I start learning Python? I only want to learn the basic shit so I have sort of a headstart when I start learning it at school.

I have some experience with doing things in Batch.

[Blasphemy]

So, I'm trying to re-create Terraria in Python ( Lol I know, Python, really? ) but yeah, I'm mostly doing it since everyone seems to think it'd be impossible. Anyway, I have it functioning with over 20 million blocks rendering at 60 FPS right now, but it's only a flat terrain. My issue is, I have no idea how to go about generating mountains, caves, etc. If anyone could point me in the right direction, it'd be greatly appreciated.

I had it, but Visual Studio decided to hide it again. It is the control where you can take a table from the DB, and drag it into the form, as either a table adapter or binded textboxes / lables, and adds all the necessary table adapters, binding sources etc. Do any of you know where the hell M$ hides it?[/QUOTE] Forgot I posted this, the solution is View - Other Windows - Data Sources or Shift + Alt + D

You can blend noise and gradients to create terrain. [URL="http://http.developer.nvidia.com/GPUGems3/gpugems3_ch01.html"]This chapter from GPU Gems 3[/URL] is in 3D but you can apply the same principle to 2D.
