C++ :: Distributing Quantity R In M Boxes
Feb 24, 2014
I have an array of size m and r resources. What would be an efficient (or just any) way of distributing them in the way shown in the table? The highest amount of resources must be concentrated in the middle of the array and all the resources must be distributed.
I'm not really set on exactly how steep the "slope" must be, I just need a way of approaching the problem.
Example with m=9 and r=13
box resources
0 0
1 0
2 2
3 2
4 4
5 2
6 2
7 1
8 0

i have a program that is a Mediastore and i have 4 classes. Produkt: which is a class with a few variables that i use to add products to my List.
public class produkt
{
public string Name;
public string price;
[Code]....
then i have my Lager class which i use to add my products to my list and Listbox. This is done by having 3 textfields where i say what the Name,SerialNumber and Price of the object i created should have.
In this class i also have 2 more textfields and a button that make it possible to add a quantity of the selected listbox object of my product Class. if the item im trying to add a quantity to dosent exist i get a question if i wanna add that product and it adds that product to the list. if however the product allready exist its suposed to add the quantity with the selected amount from my textbox.
Then I have my Class Kassa which is a Form with 2 Listboxes. The first listbox share the same List as the one in my Lager class and the other listbox is the listbox which i use to take items from my produktlist and put it in my checkout "basket" then i am suposed to be able to choose one of these items from my checkout basket put the amount i want of that item into a textfield called KvantLEv and press the checkout button to be able to simulate a checkout and then this selected item's quantity is suposed to be lowerd by the specified amount and is to be removed from the checkoutlistbox but this aint working... this is my checkout function so far
private void cashout()
{
produkt p = new produkt();
int a = VaruKorg.Items.Count - 1;
[Code]....

I am attempting to write some code for a flow meter and LEDs using my Arduino. I need the flow meter to count a certain quantity of fluid, then light up an LED which corresponds to that quantity. I found this code on the internet and it was exactly what I needed but when I opened up the serial monitor to see if it worked it didn't. I have finally fixed the issue with it not counting anything at all, but it is still acting as if it was measuring the rate. how it counts and keeps track of how much fluid in total has passed through the flow meter ?
volatile int NbTopsFan; //variable to accumulate the number of pulses
float Calc = 0; //the volume flowed since measurement started, liters
void pulse() //This is the function that the interupt calls
int hallsensor = 2; //The pin location of the sensor
const int led1Pin = 3; //pin for LED corresponding to volume1
const int led2Pin = 4; //pin for LED corresponding to volume2
[Code] .....

Basically, I am designing a form that shows all of the services a mechanic performs, and then it is supposed to calculate the total based on the selections made.
HOW do I use those check boxes to calculate a total? I am supposed to use value-returning methods that solve for the parts cost, flush charges, tax charges, misc costs, etc. Ive attached a picture of the form thus to make sense of what I'm trying to describe.

So I am writing a multiform multiclass project for a class and I initially set out to create a validate class to check all of my text boxes. However after writing a few simple boolean functions to check if the box was empty or not, or if it was indeed an integer, decimal ect. I realized I was going to have to call these functions for every text box and also have all of my decision making based on the returned boolean variable still in the code portion of my form. I was wondering how do most people do it, should I write a class that validates the entire form at once(one form has 7 text boxes, one has 9). I suppose I am asking what would the industry standard be, how would a professional do it? While my simple functions would work, and while I could write one large function that validates them all at once both paths leave something to be desired in terms of re-usability for the entire form validation, and compact/cleanliness of code for the simple functions.
My validate class currently stands like this:
class Validate {
bool isValid = true;
int trash;
bool valid_string(string input) //parameter is textbox.text property {
if (input == string.Empty)

Here's what i'm searching for: I have a form with 3 pictureBoxes (pictureBox1,2,3). The form also contains one button.
What I want is that when the user clicks the button (so button_click event) that the 3 pictureBoxes each show a different picture. And when I click the button again again 3 different pictures will load.
I already found out that I need to make an arraylist for the pictures (there are about 100 pictures). A System.Random
to select random images. But I have absolutely no clue on how to write this code.

How would I make it so that I can have someone input the length, width and height for all 3 boxes and then have it output the sum and average volume? Here's an example of what I would like:
INPUT - Enter Box 1 (Length, Width, Height): 10.1 11.2 3.3
INPUT – Enter Box 2 (Length, Width, Height): 5.5 6.6 7.7
INPUT – Enter Box 3 (Length, Width, Height): 4.0 5.0 8.0
OUTPUT – The sum of the volume is 812.806
OUTPUT – The average volume is 270.935
Here's my original code:
#include <iostream>
using namespace std;
double box(double length, double width, double height); // use double data
int main() {
double sum;
sum = box(10.1, 11.2, 3.3) + box(5.5, 6.6, 7.7) + box(4.0, 5.0, 8.0);

I've finally managed to do something with the combo box but knock down one wall it's like there's another one five inches behind it. What I mean is I've figured out how to add items to the combo box and have them show images in my picture box. Only problem is when I went to debug my combo box kept looping it's options over and over and over.
Private Sub
xpmaleskincolorselect.Items.Add("Tone1"); malesprite.Image = My.Resources.Resources.XP_Female_clear;
xpmaleskincolorselect.Items.Add("Tone2"); malesprite.Image = My.Resources.Resources.XP_Male_tan;
xpmaleskincolorselect.Items.Add("Tone3"); malesprite.Image = My.Resources.Resources.XP_Male_dark;
End Sub
The subs, I know they aren't right but its just to show I know where they go. Anyway using Private Sub and End sub doesn't seem to work. I'll type them in then at the error box at the bottom it'll say that it doesn't exist in the namespace. Same thing happened when I tried to add public class beforehand to see if that would work same thing about the name space.

I've recently started creating a bingo caller application. I need in changing numbers to different text boxes. When a number is called it will be displayed in a text box and the last four numbers previous to that. However the oldest number needs to delete and for the remening numbers to move when a new number is called.

I'm using CStatic inherited class in my code and creating static text boxes dynamically. Now for assigning unique control ID I'm creating a static control from resource editor and destroying it before calling CStatic::Create() and using its control ID say ID_STATIC_SAMPLE.
If I do not use this parameter of Create(), the static control is also being created, so what is the use of this unique ID. And any other better way to assign a ID for dynamically created static controls.
