I've been working on a homework assignment that randomly generates integers and populates them into an array (array1). The program is then supposed to:
1.) copy those values to a second empty array (array2)
2.) sort the values already in array1 (using an inline function)
3.) enqueue the unsorted integers from array2 into a heap vector
4.) a third empty array (array3) is supposed to be populated with those unsorted integers (by dequeuing them from the heap), sorted in reverse order.
But no matter what I do, I always get garbage values like these:
I've tried using both a standard random number generator:
array1[i] = rand()%100+1;
And the d_random.h file my instructor gave us, but nothing works.
Here's the code from all 3 files:
HeapTester.cpp
Code:
#include <iostream> // Provides cin, cout
#include <cstdlib> // Provides EXIT_SUCCESS, rand, srand
#include "d_random.h"//Provides random number generator
#include "Heap.h"
using namespace std; // Use C++ Standard namespace
//Elements in each array.
const int arrayLength = 15;//100;
[Code] ....
Why I'm getting those garbage values?

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)
[Code] ......
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.

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.

View 1 Replies View RelatedI have a submit button, where users are clicking after entering text into textboxes and (hopefully) check boxes (for yes/no).
Here is my code, and when I run it and press submit, there is no action. It just continues to loo.
string ConnectionString = @"Data Source=.SQLEXPRESS;
AttachDbFilename=|DataDirectory|ASPNETDB.MDF;Integrated Security=True;User Instance=True";

Note: I took out the Checkboxes in the code to hopefully get a successful run, to no avail.

I made 2 forms and Form2 has buttons with images like planets and game wallpapers etc. When I write the code for button:
this.BackgroundImage = new Bitmap(Properties.Resources._8_8008_by_amplifier404);
this.BackgroundImageLayout = ImageLayout.Stretch;
// where _8_8008_by_amplifier404 is name of the image located in resources
It only changes background in form which has those buttons as long the form is used. Once I go back to form1 it's changed to null. How to set background in all forms with a button click which will be there until another button with an image is clicked.

In my class I'm trying to display the elapsed time as my label on a windows form. I've been reading up on all the different articles online and have tried these three methods all with the same result:
1. Using the System.Timers class
2. Built in Timer sub-class
3. Defining directly inside of my class the StartTime, etc. variables.
All of these still result in the following error:
Cross-thread operation not valid: Control 'User_Interface' accessed from a thread other than the thread it was created on.
Currently, my windows form is being called by another class, but I'm not sure if this is the cause of the problem.
This is a sample of the code that I'm currently using to show the elapsed time:
private void OnTimedEvent (object source, ElapsedEventArgs c)
{
TimeSpan time;
currentTime = DateTime.Now;
