C# :: Update Initial Values Once User Has Added To Inventory
Apr 10, 2015
I am having some trouble creating a listbox in visual studio. I declared an array, set initial values, and now I would like to be able to update those values. It is a pizza inventory app, so I need to update the initial values once the user has added inventory. This is the code I have for the "Update Inventory" button:
// read in value and convert to double
double dblInput = Convert.ToDouble(txtInput.Text);
// loop through ingredients and add inventory to selected ingredient
for (int i = 0; i < dblInventory.Length; i++) {
// is item at i checked for update?
if(lstInventory.GetItemCheckState(i) == CheckState.Checked)
[Code]....

Write a constructor that initializes a new inventory object with the values passed as arguments, but which also includes a reasonable default value for each parameter.
#include "stdafx.h"
#include <iostream.h>

I have a program that is reading six characters from a text file, swapping every other character(ABCD would read BADC), and then adjusting their value based on a user's adjusted value input. If the adjusted value is 5 then letter A becomes F.
The final output line should print the initial six characters followed by the final six characters after the swap and encrypt adjustment.
I can only manage to print the final characters. Am I far off thinking I need to use pointers to point to the original character values?
One more thing: instructor wants us to complete this project as simply as possible meaning without the use of arrays, loops, switch statements, etc.
#include <iostream>
#include <string>
#include <fstream>
using namespace std;
int main() {
//declarations

Goal: Write a program that compares the values stored in the first array to the user inputted values in the second array.
In order to fix this error: [URL]...
I had to change my array initialization to one with a star in front of it:
char a1[]={"a","d","b","b","c","b","a","b","c","d","a","c","d","b","d","c","c","a","d","b"};
to:
char *a1[]={"a","d","b","b","c","b","a","b","c","d","a","c","d","b","d","c","c","a","d","b"};
I also changed my 2nd array to one with a star in front of it: char *a2[20];
What does this mean exactly? Putting a star in front of an array?
Also, I am now getting an "unhandled exception" when I try to get input for my 2nd array:
cin>>a2[i];

I have a semi-working program for doing this task. Here it is:
char c = 0, flag = 0, c_ = 0;
while ((c = getchar()) != '.') {
if ((c >= '0'&& c <= '9') && (c_ <'0' || c_ >'9')) {
if (c == '0')
flag = 1;
} else putchar(c);
[code].....
But when I enter "000000a123000500" the program returns "0a23000500" instead of "0a123000500". Please change my program to have it do what it need to or give me some hint. Using getchar and putchar only! No massives and pointers!

I've been trying to store the inital size of a list in an int variable, so I can access it later in case I modify the list size. For example, I did the following:
std::list<AType *> myList;
myList.push_back(anATypeobject);
int initListSize = myList.size(); //initial list size
myList.push_back(anotherATypeobject);
myList.push_back(yetanotherATypeobject);
while(myList.size > initListSize)
myList.pop_back();
What this is supposed to do is to get an initial size of a list, and then be able to return to that initial size. However, when I try to do it in my code, initListSize always change if myList.size() changes. Is there a way to change that?

Define a constant PI that has a value of 3.14159
- Create a double variable, Radius with an initial value of 10
- Create two double variables. Circum and Area, without initialization
- Using the following formulas, compute circumference and area of the circle:
circumference = pi * r * 2 (here, r means radius)
area = pi * r * r
- Display the result using three variables (numbers must come from variables)
- Expected output: (Don’t forget to display the period at the end of the first line)
Circle with radius of 10.
Circumference = 62.8318 Area = 314.159

So I'm writing an RPG and I'm in need of an inventory system. Of course as an relatively old member of the forum I know best than just come here and ask so I've already researched quite a bit and I've formulated this idea.
I've kind of conceptualized it like so: I'll have some sort of STL container of a unique_ptr of my base item class. There will be derived item classes. Taking advantage of polymorphism I can then call the new Derivedclass when inserting it in the STL container.
My questions are: What STL container should be used for the inventory(fixed sized)?

There was an "impovement" since Windows 7 in algorithm for selecting the initial directory, which is described here OPENFILENAME structure. Briefly:
Windows 7:
If lpstrInitialDir has the same value as was passed the first time the application used an Open or Save As dialog box, the path most recently selected by the user is used as the initial directory. Otherwise, if lpstrFile contains a path, that path is the initial directory.
Otherwise, if lpstrInitialDir is not NULL, it specifies the initial directory. If lpstrInitialDir is NULL and the current directory contains any files of the specified filter types, the initial directory is the current directory. Otherwise, the initial directory is the personal files directory of the current user. Otherwise, the initial directory is the Desktop folder.
The problem that this behavior is not what users of my program expect. Another constraint is that I need to use old CFileDialog dialog, not Common File Dialogs. I've tried to use advises described on StackOverflow and on MSDN. This solution by EllisMiller works perfectly:
Specifying a full path (including filename) in lpstrFile. The filename of course shows up in the filename box which is annoying. I ended up using a filename of "." and adding a bit of code to clear the filename combobox once the dialog is open.
BUT I can't figure how to clear the filename combobox. I've tried to add hook procedure, enumerate windows and clear text, but this didn't work for me. So, my question is: how can I clear text in the filename combobox of CFileDialog?

#define WEAPONBEGIN_WOODENSTICK (1)
Which will go instant ( when u create character ) to inventory. And:If i have 1, 2, 3, 4, 5, 6, 7, 8, 9 slots ( example ) and i sell item which was on 3rd slot, what will happen with others ? will they just go back for one slot or ?

How would i do this? Im trying to create an inventory but this just will not work, when i do it how i have it originally (as shown below):
cout << "Do you have weapons and armor?: ";
cin >> yEquip;
if (yEquip == 'y') {
cout << endl;
string invintory2[6] =
[Code] ....
the program outputs this:
cout << "Do you have weapons and armor?: ";
cin >> yEquip;
if (yEquip == 'y'){
cout << endl;
string invintory1[6];
[Code] ....
however programing it like this seems very... time consuming.
my other arrays (normal ones that just hold a set of int's) look like this:
int *player[] = {&yhp,&ymp,&ypatk,&ymatk,&yratk,&ypdef,&ymdef,&yrdef,&ydb,&yacc,&ycr,&yas};
Is there any way to do a string array in this way?

I'm trying to create an inventory system in C++ using classes and objects. Here is what I have now
Item.h
#pragma once
#include <iostream>
#include <allegro5/allegro.h>
#include <allegro5/allegro_image.h>
[Code]....
Basically what I want my inventory system to become is this: [URL] Each slot can hold an item.
Basically this inventory system should be able to do what RS Inventory system can do. (Hold items, Use items, Equip Items (No need for moving item))

So my inventory program runs fine as far as I can tell. Except when entering "Amounts" with more that 1-precision . ie
Amount Entered : 25.99 // Problem
Amount Entered : 25.9 // No Problem
When entering say 25.99, the rest of the file is jibberish. but 25.9, the rest of the file is fine
Code:
#include <stdio.h>
typedef struct toolRecord{
int record_num;
char tool_name[16];
int quantity;
double price;

You are requested to create an inventory control application for a drink stall (give a name to the stall). The application is used to show the list of drinks the stall sells, how many of each item on‐hand and the cost of each item. The records are to be saved and retrieved to/from a binary file called “drinks.txt”. For each drink in the stall, your program is to keep the information as a Record Structure called DrinkRecord. The structure should at least consist of the following:
(1) Item Number
(2) Item Name
(3) Quantity
(4) Unit Price
Your application should have the following features:
(a) Display a drink information
(b) Add a new drink information
(c) Update a new drink information
(d) Delete a drink information
(e) Display all drink information
#include <string>
#include <fstream>
#include <vector>
#include <iterator>
#include <algorithm>
#include <stdlib.h>
#include <iomanip>
[code].....
Everything works fine with minor issues, but I'm having trouble with the editing function. I need to be able to search for a specific drink then be able to edit its contents and print the new contents to the file. I have not created a structure yet. I will do that as soon as possible.
