C# :: How To Stack List Items

Nov 18, 2014

I do some research about getting the coordinates from the list items but without success. I would like to make that when i press down my mouse button that little blocks fall "out" my mouse and stack on top of eachother.

that first works. When i press the mouse button i draw squares and the fall to the bottom of the screen, but the stack part not.

here is my code:

using System;
using System.Collections.Generic;
using System.ComponentModel;

C++ :: Program To Save List Of Items With Associated Attributes

Nov 22, 2012

I'm supposed to write a program that is able to save a list of items such as books, CDs, or DVDs. The items that are saved must have attributes associated with them. For example a book has a title, author, publisher, and ISBN.

I'm supposed to create a program that is able to save the database of items to a file on the hard drive and also retrieve it from the hard drive.

The user should be able to

1. Enter items
2. Display a list of the items
3. Save the list to disk
4. Read the list from disk
5. Sort the list
6. Exit the program

I know I should use arrays and structs but I don't where to start.

C++ :: Stack Based Linked List

Oct 23, 2014

I am trying to program a stack based linked list. Something very weird is happening with my program. Whenever i want to print with cout<< in specific places, it actually changes the data of the stack. Also, using endl after the cout also changes the data of the program.

#include <iostream>
using namespace std;
class node {
public:
int number;
node* nextPtr=NULL;

C/C++ :: Implementing Stack Using A Double Linked List

May 12, 2014

So im trying to write a code that will take data in from a user and when that user enters specific character then i want to pop the top of the stack and place that node on a new stack. Then if the user enters a different specific character then i want to place what was just popped off the stack back on to the original stack. Anyways i'm just testing what i have without all the complicated stuff with the specific characters, but i get an error and i'm not not well versed in exception handling. So this is what i have so far. the push seems to work well but the pop seems to be giving me problems.

Stack::Stack(){
top = NULL;
bottom = NULL;
}
//method to push a line of text onto the stack
void Stack::push(string data)

C/C++ :: Linked List Implementation Of Stack For ReverseRows In Matrix

Nov 29, 2014

I had the following question in my exam paper and only got 2.5 out of a possible 7 marks.

Given the Matrix class:

class Matrix {
public:
Matrix(unsigned r, unsigned c);
Matrix(const Matrix<T>& rhs);
~Matrix();
const Matrix<T>&operator=(const Matrix<T>& rhs);

[code]....

Use the linkedStackType class (Linked list implementation of stack) and write a function reverseRows to reverse the order of rows in the matrix. Note that reverseRows is not a member function of the Matrix class therefore only the public interface of matrix can be used.

template<class Type>
struct nodeType {
Type info;
nodeType<Type> *link;

C++ :: 2D Array To Simulate Linked List For Stack Construction

Feb 13, 2013

I'm trying to implement 2d array to simulate linked list for stack and I faced several difficulties doing so.

How do I implement from Top to Bottom ordering? How do I check random index value for validity?

Source-code:

Code:
#include <iostream>
using namespace std;
int myTop, index, nex = -1;
int twoDimentionalArray[25][3], L[25];

[Code].....

And one more thing: how do I get straight 0 from 25 index in the first coulumn?

C/C++ :: How To Access Linked List Functions From Stack Class Without Functions

Mar 20, 2014

I'm a little confused by my programming assignment this week. I've been working at it Wednesday and I've made progress but I'm still confused as to how I'm supposed to do this. The class I made is called Stack, and it's derived from a template class called StackADT. We also utilize a class called unorderedLinkedList, which is derived from a class called linkedList.

We're supposed to implement all of the virtual functions from stackADT in the Stack class. The Stack data is stored in a an unorderedLinkedList, so what I'm confused by is how to implement a few of the Stack functions because there are no functions in unorderedLinkedList which we could call to manipulate the data.

As you can see from my attached code, I'm really confused by how I'm supposed to implement the pop() and top() functions, and I also think my initializeList() function is wrong. We don't have any similar functions in unorderedLinkedList to call, so I'm at a loss of how i'd access my unorderedLinkedList. My initial thought was to call the similar functions in the class that unorderedLinkedList was derived from, linkedList, but I'm unsure of this is what we're supposed to do, or if theres actually a way to access my unorderedLinkedList without having to use the functions from the base class.

NOTE: We're not allowed to modify stackADT, unorderedLinkedList, and linkedList.

Stack.h

#include "stackADT.h"
#include "unorderedLinkedList.h"
template<class Type>
class Stack: public stackADT<Type>{
template <class T>
struct nodeType
{
T info;
nodeType<T> *link;

But when i try to ptint id of second item std::cout<<"Item Id ->>>>>>>>>>>>>" << collection[2].GetId() << std::endl; it gets a blank value. but size of the collection is 82, get the correct value for the collection size.

C# :: Removing Items From ListBox

Mar 5, 2014

I'm working on creating a windows form with a listbox, textbox, and 2 buttons (add,remove). I need a way of removing every string matching the contents of the textbox from the listbox. Here's what I have:

for (int i=0;i<listBox1.Items.Count;i++)
{
//...
listBox1.RemoveAt(i--)
}

Seems to work, but I need a way to show a error message once the user clicks 'remove' and no items in the listbox match.

C# :: Display Items From Dictionary

Jan 18, 2014

I am creating a student management system (using classes) for my assignment and am stuck with designing UI. I made the classes but am not sure what the best control is to display items from a Dictionary<> object. Right now I am using the ListView because of the columns in details view...just want to know if there is a better, simpler control I could use if i want to display data (without using sql)...or is the good old "next" and "previous" option the simplest?

C++ :: Switch Statement - Summing Items

Nov 6, 2014

I'm creating a program that is combining functions to show a menu to a user then the user picks numbered items which results in the totalling of a bill for them.

Where I'm stuck is after they're entered their selections, how to take them and sum them up. I've been trying with a switch statement, but I'm not sure if this is the right method. Is it even possible to sum separate cases of a switch statement together? Below is the code I've gotten so far:

#include <iostream>
#include <iomanip>
using namespace std;
void showMenu ();
void showBill (double, double, float, double);
void changeDue (double, int);

C++ :: Using A Textbox And Other Items Between Multiple Forms

Oct 31, 2013

I am writing a program in Visual C++ 10 with 2 forms.

In the first form I have a textbox and a button. The button opens the second form.

In the second form, I have a button that changes the text in the textbox in form1 to an item from a listbox in form2.

Here is my problem. When I do the code for the button in form2 to change the textbox in form1 I get the errors:

error C2065: 'textBox1' : undeclared identifier
error C2227: left of '->Text' must point to class/struct/union/generic type

I thought maybe I should just include the "Form1.h" file but I can't do that because I already included "Form2.h" in form1 in order to be able to open the second form. If I try to include form1 in form2, it says that the code to open form2 is an error now.

My question is, how can I access identifiers such as "textbox1" from other forms and other files when I already used the first form to open the second form? I also want to know how to do this for all identifiers between all files.

how to print the selecteditem from a listbox into a textbox because that doesn't work by just setting them equal either.

Here is my code:

#pragma once
#include "Form2.h"
namespace Test1 {
using namespace System;

C++ :: Dynamically Deleting Items Out Of Vector

Aug 31, 2014

I have the following code in which I wish to dynamically delete items out of a vector based on the condition of the item in the vector.

The below code works but throws the error: "vector iterator not incrementable" at certain times.

It seems like this happens when the last item in the vector get's deleted. How do I solve this problem?

for (std::vector<PhysicsObject*>::iterator it = CurrentBoxes.begin(); it != CurrentBoxes.end();/*it++*/) {
(*it)->CalculatePhysicsOrientation();
(*it)->DrawMe();
glm::vec3* CurrentBoxPosition = (*it)->GetCurrentPosition();
if (CurrentBoxPosition->y < -750.0f) {
it = CurrentBoxes.erase(it);
}
++it;
