C/C++ :: How To Use Node Struct In Test Driver

Jul 24, 2014

I have a file system class that has a struct named Node declared private as so:

class FileSys{
private:
struct Node {
Node* next;
Node* prev
Node* parent;
int key;

[Code] ....

But how would I get to the Node struct? I tried to do this in the main but of course I received an error:

FileSys FS_Obj;
FS_Obj Node* T = new Node;

With errors:

Error: expected ; before Node
Error: Statement has no effect

C :: Unable To Return Struct Node Without Using Pointers

Jul 20, 2014

I'm quite new to C and these days I have been playing around with a linked list. I managed to make a working version using pointers, ad only for the sake of learning I was trying to do the same thing just passing the "Object reference" Here is the method that apparently doesn't work..

Code:

struct Node addNode(struct Node head){
int value;
struct Node *n;
printf("Please enter the value
");
scanf("%d", &value);

[Code]...

when I return the function i have something like: head=addNode(head)

Unfortunately it does not work the way I aspect. I suppose that there is something I have left out..

Code:
like n->next=&head
// passing the address of the head at the next pointer of the struct
head =*n
//copy the values of the new node to the old head..

There must be something wrong with this line.. return head; What have I done wrong?

C# :: Treeview Node Selection Show First Node Of Tree Instead Of Selected

Apr 22, 2015

I am working on C# Project [Windows Form Application], to update treeview nodes from excelsheet [xls] Cell [row i, Column 3] Values, while on selecting treenode, it should update corresponding Column 4 Value [row i, Column 4]. For me, Treenode are populated successfully, but on selecting the treenode, it always display first Element of treenode [Not selected one].

Populated Treenode from Excel as: [ Update Child Nodes from Column 3 elements [Column 2 Contain Parent node name and Column 3 have Child Node name], if Column 2 Value is same as Parent node name [My Module], update the child nodeunder same Parent node.]

for (int i = 0; i < worksheet.UsedRange.Rows.Count; i++) {
string mynode = ((Excel.Range)worksheet.Cells[i + 1, 3]).Value2.ToString();
string mynode2 = ((Excel.Range)worksheet.Cells[i + 1, 2]).Value2.ToString();

[Code] ....

On selecting the Child Node, it always give 1st Parent node. Instead of Selected Node.

for (int i = 0; i < worksheet.UsedRange.Rows.Count - 2; i++) {
string mynodetext = ((Excel.Range)worksheet.Cells[i + 2, 3]).Value2.ToString();
string mynodetext1 = ((Excel.Range)worksheet.Cells[i + 2, 4]).Value2.ToString();
if (treeView1.SelectedNode.FirstNode.Text == mynodetext) {
this.richTextBox1.SelectedText += Environment.NewLine + mynodetext1 + Environment.NewLine;
}
}

How to get correct selected Node.

C/C++ :: How To Use UMDF Driver Request Buffers

Feb 18, 2015

I am trying to create "dummy" drivers for testing purposes of another program of mine.

I want to be able to Call DeviceIoControl and pass a string in as the buffer and then receive that string in the driver, change it and return it. But right now I am not able to receive the string, when i get the buffer and print it out it is garbage. Where am I going wrong?

TEST

int _tmain(int argc, _TCHAR* argv[]) {
BOOL freeResult, runTimeLinkSuccess = FALSE;
HANDLE RTC_IOControlHandle = NULL;
HINSTANCE FRS_IOControlHandle = NULL;
RTC_IOControlHandle = CreateFile(L"\.ROOT#SAMPLE#0000#{db3d5a0e-63aa-4b97-9d05-b50d5093a20f}",

C++ :: Implementing Classes And Creating A Driver Function?

Nov 30, 2012

For this problem, you will design and implement 2 classes and then write a driver function to test these classes. The first will be a C++ class for an abstract data type color with a public enumeration type colorType that has the color values shown in Listing 10.8. Your abstract data type should have an attribute for storing a single value of type colortype and member functions for reading (readColor) and writing (writeColor) a color value as well as setting and accessing it. The function readColor should read a color as a string and store the corresponding color value in the value attribute of a type color object. The function writeColor should display as a string the value stored in the value attribute of a type color object (see Figure 7.5). Modify class circle and the driver function in Listing 10.9 to include and use this class. You'll need to remove the declaration for color in class circle. Test your modified driver function with the new color and circle classes.

The second class will be to design and implement a rectangle class similar to class circle. Be sure to incorporate the new color class you have written and tested in the first part of the programming exercise. Write a client program that asks the user to enter a shape name (circle or rectangle) and then asks the user for the necessary data for an object of that class. The program should create the object and display all its attributes.

The circle class .h and .cpp files as well as the original driver function will be supplied. You are to provide the .h and .cpp files for the new color class and the modified driver function as well as the .h and .cpp files for the rectangle class and the client program that uses all three classes.

What I have so far, and I'm pretty lost;

color.h

Code:

Code:
//color.h
//Color class definition
#include "stdafx.h"
#ifndef COLOR_H
#define COLOR_H
class color {
public:
enum colorType {black, blue, green, cyan, red, magenta, brown, lightgray, nocolor};

C/C++ :: Sizeof (struct) Returns 6 More Bytes Than Actual Struct Size?

Sep 14, 2014

#include <stdio.h>
#define MAX_USERS 20
struct {
char ID[10];
char Name[40];
int Pos;

[Code] .....

I was attempting something weired with address to move data around when I discovered that the size of the array is not what I expected. I am passing this structure as &Users to a function that declares it as a void *, then I can deal with chunks of data (memmove) and not have to worry about index or things like that. However...sizeof is returning something I do not understand.

C# :: GUI Based Test Automation

Aug 7, 2014

I am new to C# and just want to understand if an entire Test Automation Framework can be built using only C#. I would not want any dependency on available commercial tools in the market for executing the Test Action steps. Though a few points that i see will need to be taken care of at the onset.

1. creating and maintaining Object repository in some form of file extension
2. preparing a GUI for capturing user Test Action Steps
3. retrieving the respective test objects from Object Repository and firing the respective Action commands on those objects
4. handling test data within the Automation Framework Solution folder.

I have been exploring a series of blogs and found that point # 2 and 4 are achievable. However points 1 & 3 above looks a big challenge.

C++ :: How To Criticize Code And Test It For Efficiency

Jan 12, 2015

- When I need to code something, what is the process I should go through to design any algorithm(s), and solve the problem in the most efficient/flexible way? At the moment, I just think up a way of solving it and if it works I will use the code in my current project, but as I have found out from some of my larger projects, this definitely is not the way to go!

- How can I criticize my own code? Again, if I write some code that works I'll keep it. Go through the code and look out for optimizations or refactor the code? Which leads to my last question...

- How can I test my code for efficiency? What are the best ways of testing algorithms (etc) that I have added to see if they are fast enough? Of course, it will probably involve some kind of timer, but how will I be able to tell if X milliseconds is a good enough time?

These codes give these errors:

These errors are related to

C++ :: Writing Test Programs Involving Constructors

I am currently trying to write a test program involving constructors. I know what I am about to ask is pretty basic stuff but Visual Studio is not recognizing when I declare strings for some reason. My code isn't completed yet but as I am typing string in to declare the variable in the class Visual Studio is not recognizing string as a usable value.

Code below:

#include <cassert>
#include <iostream>
#include <stdio.h>
#include <string>

using namespace std;
class college {

Like I said... this is completely unfinished I just need to understand why my strings aren't being recognized.
