I decided to make a linked list program using classes and templates.I implemented my linked list and added some basic functions, everything worked just fine. Then I proceeded to add templates...First, the error list:
#pragma once
template<class T>
class Node {
private:
Node* next;
[code]....
To sum up: Something's wrong with the templates that I used in "List.cpp" and what it could be.
I am having problems implementing ArrayList using templates. I was given a program and I have to create this implementation to make it work. It keeps giving me an error "invalid operands to binary expression" .....

#include "List.hpp"

I am trying to implement a linked list using a class template, however each of my classes that I want in the list all inherit from an Account class. I have attempted to template the linked list class as account however Ive come into errors I can't resolve. How I can go about this?
The error exists within the customer.cpp class where it says
14IntelliSense: a value of type "Account *" cannot be assigned to an entity of type "CurrentAccount *"f:Further C++Assignment with TemplatesAssignmentCustomer.cpp229Assignment
Customer class:
#ifndef CUSTOMER_H

If I wanted an int connected to a float connected to a string connected to a POD, would all I have to do is :
Code:
template<class T, class X>
struct node {
T data;
node<X> *next;
};
Or would I be forced into using polymorphism?

I have a table in my database that has a 3 fields.
RuleID | RuleName | Rule
the ruleID is a randomly generated string of characters, RuleName is the name the user gives to the rule, and the Rule field is about 600 characters long and is just XML text.
I want to read that Rule field from the database and use it inside the function below.
private static List<MenuItem> LoadRules(bool evaluationType)
{
//string path = HttpContext.Current.Server.MapPath(string.Format("/Rules/{0}/{1}/", ip, evaluationType ? "Evaluation" : "Execution"));

This function loads an xml file from a static location and parses out some information to a context menu.

I am currently having issues with the following code when trying to create a excel file using C#. This is the code that I have at the moment.
oXL = new Microsoft.Office.Interop.Excel.Application();
oXL.Visible = false;
oWK = (Microsoft.Office.Interop.Excel._Workbook)(oXL.Workbooks.Add(System.Reflection.Missing.Value));
oWK.SaveAs(path + "" + fileName);
oWS = (Microsoft.Office.Interop.Excel._Worksheet)oWK.Worksheets.get_Item(1);
oWS.Cells[1, 1] = "Student ID";
oWS.Cells[1, 2] = "Student Name";
oWK.Save();
The line that I am having issues with is
oWS = (Microsoft.Office.Interop.Excel._Worksheet)oWK.Worksheets.get_Item(1);
If I remove it, I am able to create and save teh workbook in the directory. However, I want to make some changes on a worksheet, and that is where the issue is. I have also tried using the line of code:
oWS = (Microsoft.Office.Interop.Excel._Worksheet)oWK.Worksheets[1];
This line had no luck either. The issue I am having is the error regarding InvalidOperationException: Dynamic operations can only be performed in homogenous AppDomain.

I am trying to create a linked list and then reverse it. So far I have created the link list however I am having difficulties figuring out the steps to reverse it. What is the logic behind reversing this linked list. I am not able to use recursion. I am supposed to create a copy of the linked list with the nodes reversed.
Code:
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
struct charNode {
char data;
struct charNode *nxtNode;

I'm working on a list of functions that can create a unique ID for a computer. Here's what i have so far:

Are there any other functions that do this?
Basically, the program is just sort of a soundboard. The way it is now, it just reads all the names of the files in a particular folder (all .wav files), and then adds an entry to a listBox for each file found. What I would like to do, is instead of a listBox, have buttons for each one. Is there any way to iterate through a list of items and create a button for each one? The main problem I see is placing the buttons. It would have to have some sort of grid to place them in I would imagine...

I am need to compare 2 items from 2 separate drop down lists. These values are of int type. Say for example 2 drop down lists showing years. Now i need to find out these 2 years selected is greater or nearer to the current year.
I tried converting the values i receive from the drop down lists to int variables. But i am getting error then. I gave it like below.
int tmp = Convert.ToInt32(ddl_1.SelectedItem.Text);
this gives an error like this - Input string was not in correct format.
I need to know how to put an item from a drop down list to a variable of int data type.
I am trying to query an Informix database using a List<T> collection's elements as variables. I can build the list and connect to the database, but I am unsure how to iterate through the list and query the database for each item in the collection.

I have to create a 2D link list with 2 level hierarchy
some thing like that
Code:
head nodes level 1: 0 1 2
/| / /|
Sub node level 2: 0 1 2 0 1 0 1 2
Real Data under |
each sub node: |
int **join=Null;
int unique = 0;
int col;
int ptr;
int *tmp_perm=Null;
int col_elem;
I know how to deal with 1 level link list structure. But i don't know how to access, delete, nodes and sub nodes from this 2 level hierarchy. C
Linked lists seem to be the most erroneous and most frequent thing I use and post about nowadays. I've been wanting to handle data structures in my own library of functions, but I'm not sure how to imitate polymorphism without too many ambiguities. I could just pass some character or string value to represent a type, but I wanted to see if there was actually something more elegant I could use before I dive in.
View 4 Replies View RelatedMy colleague and I have been given a task to create a list with the employes of a company using binary trees. Each employee/node has to contain the following information:
- Employe name
- Rank
- ID Number
- monthly Salary
We have to write a C program (using Codeblocks) which builds the company tree with the information above and afterwards lists all the employes who have a salary bigger then a number specified by the user.
So far so good. We've had a look on the examples on the internet and after finding one which looked friendly enough we started working on that one to suit our needs. Credits for the original source code to: C Program to Implement Binary Search Tree Traversal - Basic C Programs | C Programming Examples
We've reached the point where we're able to insert the required information but being able to list all the employes who's salary is bigger then the number given by the user seems to be rather difficult to achieve. I'll include the code next. We have left almost the entire pieces of the original code and we are aware that the are still things which are not required for our assignment, which only requires to enter the 4 information above and afterwards display the employes with the before mentioned condition concerning their salary.
Code:
# include <stdio.h>
# include <conio.h>
# include <stdlib.h>
typedef struct BST

I want to display the content of my database in list view. The table has 5 columns however when I tried this code
string view = "Select * from cust_infor";
SqlCommand cmd = new SqlCommand(view,FL.clsconnection.opencon());
SqlDataReader dr = cmd.ExecuteReader();
listView1.Items.Clear();
while (dr.Read()) {
listView1.Items.Add(dr[0].ToString()).SubItems.Add(dr[1].ToString());
}
It limits the display to 2 columns. List view will only show the first 2 columns. The code above won't let me add more indexes or subitems. Only up to 2 columns.
I am grabbing data from three entities and want to grab a field value in each of the entites and place it in an arraylist. What I would like to do is loop through the arraylist for all the values and do something for each value only once. If the value in the array list is repeated, I want to not do anything for it and continue till the end. Basically, I loop through all the values do something for each value and skip over the repeated value if I already did something.
