Feb 24, 2014My assignment for class was to create a Student ADT. I have three files. First one is Student.h which defines a Student record and has the prototypes of the functions that can be used with Student. I have Student.cc which is where the functions are actually declared. And my final file is testStudent.cc where the "main" function is that is creating a Student and callign all of the functions to make sure they work properly.
I have all of the functions working properly, except for my destroyStudentRecord function. It is supposed to deallocate the record, but I am unsure of how to actually do this. The current implementation appears to only deallocate the firstName field, as when you display the record after deallocationg it, everything still shows up except the first name. I have tried deallocating each field of the record before deallocating the record itself and that gave me the biggest list of errors I have ever seen.
I realize the implementation of some things in here might be a bit odd, but this is exactly how we are required to do things for this assignment and nothing about the implementation can really be changed unless something is actually just plain wrong(which is of course a possibility as I am quite new to this!). As I said though, everything else is working exactly as it should be, so my only issue at all is with actually deleting the record once I have created one.
Student.h:
#include <iostream>
#include <cstdlib>
using namespace std;
#ifndef _STUDENT_H_
#define _STUDENT_H_

1) output in text/.exe file display random characters.
2) Data obtained from New_Staff unable to pass into Export_Profile.
3) a new output will overwrite the existing information in the text/.exe file
4) the delete function unable to delete correctly after the first time i delete a staff information in text file.
The code is as follows:

C Sharp :: Display SQL Database Record In List View Using C#
Oct 6, 2012I 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.

May 22, 2013I have created a shared object in Ubuntu (libMYLIB.so). I am now trying to compile a simple test program (testmylib.c) to see if the shared object is properly built. I am getting an error that the build cannot find the shared object. My build command is:

where /dir/mylib is where my source and libMYLIB.so reside.

Jan 13, 2015I have been given a task of checking the size of file in Linux machine using C Program. Below is what I came up with
Code:
#include <stdio.h>
void main(int argc, char **argv) {
FILE *fp;
char ch;
int size = 0;
[Code] .....
But Now I have been asked to modify this code in a way that instead of passing the file name as parameter, I have to make a database connection and fetch the value of the filename and location from the database table and check the size . My program has to repeat this process every ten minutes, which means every ten minutes my program has to hit the database, fetch the value and check the size in the file system.
I heard like I Have to create a Fork Call, and have the child instance run every ten minutes.
C++ :: How To Create A Database
Feb 28, 2013I'm trying to make a database that stores the information without overwrite it. I want this program to store the client’s selection in somewhere that doesn't change and also that creates a new storage for the new value any time the client enters a new selection instead of overwriting it. I did something like that in my code but any time the program runs again and the client enters a new selection, the client’s selection is overwritten with the new value. I don’t know if it’s possible to do that (store the client’s selection in somewhere where doesn't change) with C++. I've been reading and I think I can create a database for my program.
THIS IS MY CODE:
#include <iostream>
#include <string>
using namespace std;

View 1 Replies View RelatedC++ :: Create Null Pointer After Using Delete
Aug 7, 2014In jumping into C++ it says something like this: It's not necessary but when you delete a pointer it's a good idea to reset it as a null pointer. That if your code try's to dereference the pointer after being freed, your program will crash. This happens to a lot of experienced programmers.
This could corrupt users data. delete p_int;
p_int = NULL;
1. If you can deference a pointer after the memory is freed, why can't you just delete the pointer?
2. If you can do 1, how do you delete the pointer using code?
3. Every thing I've read says that free memory is handed out in a sequenced order. I don't believe that is true at all. I may be wrong. Why can't you put the data in any number of places if it will fit. Isn't the compiler smart enough to know where bytes (bits)and pieces are stored?
4. If you storing anything in free memory must use a pointer to it?
5. Can a pointer or something similar be used with stack memory?
C :: Program Crashing When Deleting A Record
May 5, 2013Code:
#include<stdio.h>
//bookData structure
struct bookData {
int recordNum;
char description[ 15 ];
int booksBought;
double bookCost;
[code]...
I am able to add records and show records, no problem. But when I go to delete a record, it crashes immediately after inputting the record number I want to delete. I don't see why. I've set it up exactly like the example in my book, having of course changed the variable names for my program. Does it have something to do with the pointer?
C# :: Create Online Application Without Revealing Database Credentials
Jan 26, 2014I want to make an online application which will connect to my database to do the stuff, but I don't want the credentials to be stored somewhere in the program or in an external file somewhere in the computer or hardcored in anyway in the code.
I think that a good solution is (but I don't know how to implement it): on program execution, the credentials will be downloaded from my website somehow in an encrypted type maybe, from an api or so.
I've not tried before to make an online application, it's the first time. But I do have knowledge of SQL and PHP and I want to try a project like this.
The technology I am going to or can use is:
* Visual C# (in Visual Studio 2010 Ultimate)
* MySQL Connector/NET
* MySQL Database on a shared host
* PHP (if needed)
