C++ :: Application To Load Other Applications In A Secure Shell Based On User Interaction
Jul 9, 2013
I will sketch the scenario I would like to get working below. I have one main application.
That application, based on user interactions, can load other applications in a secure shell. This means these child applications cannot interact with the OS anymore, nor with each other.
The parent program can at any time call functions of these child programs.
The child program can at any time call functions of these parent programs.
How to implement this in C++? Preferably both parent and child should be written in C++.
The performance of loading the child applications doesn't matter. The only thing that matters is the performance of the communication between child and parent.
I dumped all symbols into C:WindowsSymbols folder, It takes more than 2 minutes to load an application which really surprises me. Why and when should I use those symbols?
Now i want to be able to change some settings at runtime using a normal Winforms App. Is there a good and easy way to change the user.config of a different application directly? I tried with ConfigurationManager but that does not seem to work.
I'm using VS 2012. Installed MYSQL 5.6, C++ Connector 1.1.3. Created a sample table using mysql. Now i like to create a connect between mysql and MFC dialog. Using this, i was try to connect.
Server Explorer -> Data Connection -> Add Connections ->MYSQL Database -> Addconnection
To get the connection, i want to enter the connection settings like:
server host name = localhost, user name =root, password=
If I pressed any letter in the keyboard means add connection dialog was closed automatically.
I create the dialog based application and draw the line inside the picture box. if line is drawn then display the msgbox, if not close the msg box and resize the window then the line is disappear and blank area is shown in picturbox.blem
i have to create a console based application in c language that can join and split bitmap images. the requirements of the application are as follows :
1. Split Image Enter number of parts: Enter source image path: Enter destination folder: 2. Join Images (all images should be of same width and height) Enter image path: Join more Image (y/n): 3. Exit
Take care of following things:
- Application should show number of images processed while running. - Acceptable Image format is BMP only. - Application should give all the validations for correct image name, type, size, path, etc.
We've been tasked write a code which would mimic a secure entry keypad.. Only recognising the digits 0-9 for the passcode, and non-numerics S (start again) C (clear last digit) and E (enter) for the control. All other key strokes are to be ignored.
The passcode has to be <10 digits and represented on the screen by "****", with any keystrokes >10 ignored. The valid passcode being 4 digits (1234).
With 3 attempts to get the correct pass code, after each fail attempt as please try again message show, where after the 3rd attempt a specific message is displayed and an alarm sounds..
I am doing an assignment that is to calculate the federal tax based on the users input. I am not entirely sure what it is doing, but it is definitely not what I want it to do. I commented out the loops because they seemed to have caused a problem, but there is still problems that are making the program do something else. Here is my code:
#include<iostream> #include<string> using namespace std; double getData(); double taxAmount();
[Code] ....
Functions just seem like they are not my thing. It never gets to the second function to do the calculations and then return to main to display the results.
I tried changing the code to a switch(status) with a default: at the end that looped the "please try again" but for some reason, that was a fail, it created an endless loop.
My assignment is to pixelate an image based on users input. I have a structure that stores the image, and in this structure I'm storing the height and width and a dynamic array of RGBA struct.
This is my function. my main issue (that I've found) is offsetting and figuring out a way to handle the "edge" if the dimensions don't add up to the set pixelation size.
I am preparing for an exam, and I am being told there will be, "1 multiple-choice question about reading a piece of code about objects interacting with functions and deciding the output."
There are a few ways I can think of:
- Passing an object into a function as an argument - An object calling a function with a dot operator - Creating a new object through a Constructor and Class(Does that count?)
Are there other ways that objects interact with functions that I am not thinking of?
It is commonly seen that computational applications accept data in notepad or excel formats to do the process on. The question is how would they do that? Do they store the notepad data somewhere in the application memory or they interact with the notepad file all the time program is running? This is my first try developing a small application .
how to stop outputting data based on a user input. The text file is as follows:
1. a 2. b 3. c
and the code I'm using is as follows:
int main (){ string line; int search; cout << "Enter a number from 1-3" << endl; cin >> search; search++; ifstream myfile ("example.txt");
[Code]...
What I want to do is to just output number 1 (the whole line) if the user enters number 1. However, I get an error on the second condition w/c is the "&& line!= search"
I'm trying to create a function where it allows the user to type in multiple amounts of integers, so if the user wanted to have 3 different storages that hold different integers, the input would look something like this:
5 97 12 31 2 1 //let's say this is held in variable "a" 1 3 284 3 8 // "b" 2 3 482 3 4 // "c" 2 3 4 2 3 // "d" 99 0 2 3 42 // "e"
Since we don't know what number the user will input every time, I'm not sure how to create a dynamically allocated array that will create an x amount of arrays every time.. I want to be able to access each index of a, b, c, d, e or however many arrays there are.
So far, this is what I have, but I'm having trouble creating the arrays since it's unpredictable. I'm purposely not using vectors because I don't really get how pointers work so I'm trying to play around with it.
int* x; int length, numbers; cin >> length; x = new int[length] for (int i=0;i<length;i++) { cin >> numbers; //this doesn't work because it only grabs the first line for some reason x[i] = numbers }
I am trying to create a program that will calculate pi based on a user input for accuracy. If the user input .3 then when the leibniz infinite sum value at a particular i becomes less then the input of .3 then the loop will exit.
I have looked at a number of examples on the internet but I feel lost. I have put together working code that will infinitely output sums but I need the loop to stop when the sum value is less then the accuracy value.
My question is what is wrong with my while loop, why will it only give me infinite summations? How do I make it so that the loop will exit when my accuracy input is greater then the sum?
int main () { double accuracy; cout<<"Give an accurate number." << flush;//looks nice cin>>accuracy; int d;//initialize denominator double pi = 0.0; while(accuracy < d){
i can't seem to get my program to save the Set.savv file and encrypt it and decrypt it when user logs back on to there virtual file on a CD and writing it to the disk its self and closing the session
I am developing an application which can be used for digitize a geographical map through GUI and mouse interaction. Well, here are the list of objects that need to be created using mouse clicks.
What will be the best design which can be used to store the data(objects) more efficiently? So that both accessing objects and rendering them will be easier and faster? I have started with Composite Design pattern to store the objects and Visitor Design pattern to render these objects.
[Code] .....
But everytime rendering is done sequentially. Will not this take more time if the number of objects increases?
Code: #include <algorithm> #include <winsock.h> void some_func() { int result = std::min (0, 16384); }
Okay, but the above code consistently gives me error C2589: '(' : illegal token on right side of '::'. I'm building with VC8. If I don't #include <winsock.h> the code compiles correctly but it doesn't matter if I #include <winsock.h> before or after including <algorithm>
I guess it might be due to one of my #defines but I've tried the code in a very minimal program and I still get the error.
I'm trying to get the hang of the declaration and use of char. I'm trying to write a program that reads sentences from the user and changes them based on their character choices, I keep getting load of compiler errors.......am I off to a good start or am I way off?
#include<iostream> #include<string> #include<cstring> #include<cctype> using namespace std; int main() { char *quit*; char sentance [100];
i want to display all the contents of a file excluding one based on user input say i have 4 records in the file numbered 1 to 4....the user chooses 2 to exclude it outputs records 1,3,4,4 when it should be records 1,3,4 what am i doing wrong here is the code.its basically displaying the last record in the file twice
I have an extra credit project where I'm supposed to calculate an approximate the user's age based on the current date and their birthday. My problem is that I am not getting the proper date and time. C++ keeps giving me some random date. I looked up c++ time format on the internet because this is extra credit and not in my book.
I am currently using dev C++ 4.9.9.2. Here is my current code :
// included libraries #include <cstdlib> #include <iostream> #include <iomanip> #include <time.h> #define cls system("cls") #define pauseOutput system("pause") void printM(int x); void age(int m, int d, int y, int &yearAge, int &monthAge, int &dayAge);
I need to create a program that prints a certain number of asterisks based on user input. The user inputs 5 and I want my program to output "*****". How would I do this in C? I've tried printf("%#**", myvariable) but this does not work it only prints "*".
Write a program to generate a report based on input received from a text file. Suppose the input text file student_status.txt contains the student’s name (lastName, firstName middleName), id, number of credits earned as follows :
Doe, John K. 3460 25 Andrews, Susan S. 3987 72 Monroe, Marylin 2298 87 Gaston, Arthur C. 2894 110
Generate the output in the following format :
John K. Doe 3460 25 Freshman Susan S. Andrews 3987 40 Sophomore Marylin Monroe 2298 87 Junior Arthur C. Gaston 2894 110 Senior
The program must be written to use the enum class_level :
The function deriveClassLevel should derive the class_level of the student based on the number of credits earned.
The first namespace globalType tys should derive the class level based on a two year school policy. and the second namespace globalType fys should derive the class level based on a four year school policy.
Four Year School Policy: Freshman 0-29 creditsSophomore 30-59 credits Junior 60-89 creditsSenior 90 or more credits
Two Year School Policy: Freshman 0-29 creditsSophomore 30 or more credits
NOTE : use ignore() function with ifstream objects whenever you want to ignore the newline character.
For example : ifstream transferSchoolFile ; transferSchoolFile.open("student_status.txt", ios::in);
while( !transferSchoolFile.eof()) { getline(transferSchoolFile,name) ; transferSchoolFile >> id >> credits; transferSchoolFile.ignore(); //Used here to ignore the newline character. …. }
I did this in parts so I got it working with a four year criteria without the user defined name spaces.
include <iostream> #include <fstream> #include <string>
