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;
}

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;

Is there a way to set the height of a listBox to show all of the items without having to kick in the vert scrollbars? I've searched on this question but can't find how to do this.

I want to kind of auto-size my listBox height to accommodate my items (within reason and perhaps set a max height which would kick in the vert scroll bars.

C Sharp :: Move Items In ComboBox?

May 17, 2012

I have a data-bound ComboBox and I populate a DataSet with the values returned from a SQL query.
 
        public DataSet CompanyArray(DataSet dataSet) {
            SqlConnection connection = InstancesTest.IDataInterface.DefineConnection();  
            SqlCommand command = new SqlCommand();
            command.CommandText = "usp_CompanyArray";
            command.CommandTimeout = 20000;

[code]....

All this works fine. The reason I populated it in an array was so that I could sort the items alphabetically. I know I could just do an "order by" in SQL but I chose this route.

What I'm after is putting a "Please Select" at index 0 in the ComboBox. How can I move this value to the top of the list, without reordering the sorted list?And I don't really want to insert a "Please Select" as a first row in a database table.

C++ :: Read N Data Items Into Two Arrays (X And Y) Of Size 20

Apr 1, 2013

Trying to do a homework assignment for a class and how to read a file into an array. I've looked in our book and on several other forums and cant seem to find any examples of this. Below is the assignment I'm working on. I have a shell of the program that I can get to run, but getting a .txt file to read into an array is something I cant seem to figure out how to do.

Write a program to read N data items into two arrays, X and Y, of size 20. Store the product of the corresponding pairs of elements of X and Y in a third array Z, also of size 20. Print a three column table that displays the arrays X, Y, and Z. Then compute and print the square root of the sum of the items in array Z. Compute and print the average of the values in array Z and print all values above the average of array Z. Determine the smallest value in each array using only one function.

Use the two data files named DATAX.TXT and DATAY.TXT.

You must use functions for the reading of the data, computing the average, printing the three column table and printing the values above average.

C++ :: How To Enable Array To Count Items From A Group

Dec 27, 2013

Arrays are by far the most fun to work with and I really need see if its possible to enable an array to count apples, pears, peaches, from a group of three each.

If any of the fruit groups were chosen how might an algorithm be put together to count how many were chosen from each group. But lets take into consideration that these fruit groups are not supposed to be randomly generated, instead they belong as an array with certain amount of chosen occurrences. To show how many fruits were chosen from each group example, 1 from group 1, 2 from group 2, 3 from group 3 the out put is the important part because it shows the group and the occurrence of that group. the algorithm should be able to display the group with an occurrence as well

C++ :: How To Properly Concatenate Two Items That Contain Binary Data

Mar 30, 2015

I have two std::string data items that contain binary data (so it may have the null character!). What is the proper way to concatenate them to preserve all of the data? I am guess a simple:

string string3 = string1 + string2;

Will not work, as it will terminate string3 on the first NULL character it encounters.
