C++ :: Console Application Should Be Like A Command Prompt
Feb 10, 2015
my C++ console application should be like a command prompt. There are "command lines" to execute in the command prompt.Here are my main prompts for spotlight:
Encode - New data entry
View - Read data from text file
Search - Find record from text file
Update - Save changes per text line from the existing text file
Delete - Delete lines from the text file
Now, I manage to do the tasks for Encode, View, and Search..But unfortunately, not in Update..I've been working this for a week already..
#include "stdafx.h"
#include "iostream"
#include "string"
#include "fstream"
using namespace std; //to omit the std
}
i want to know how to copy data from already written text on console?
i am actually making a program that reads texts already printed over console so i want to capture that data again but i must not have a copy version of every thing behind the scenes i.e. in the background. I need to know how to capture data or amount of some data from console output? for example:
[console started]
It's imaginative console for the purpose of understanding.
I will make a very impressive program which will wow! you and to my instructor. |
[/console ended]
Now i have no copy of any data printed on console/command prompt or whatever you say it. My question is how can i copy following strings from console?
1) It's imaginative console for the purpose of understanding.
2) It's imaginative console for the purpose of understanding.

3) very impressive program
4) understanding.

Moreover in case you need about my IDE, i am using : Windows 7 Ultimate Service Pack 1. Microsoft Visual Studio 2013 Ultimate. Architecture 64bit.
I have created a MFC dialog based application. Now I want to implement such a functionailty that I will be closing my application through command prompt. And while closing of my application the ExitInstance() method of my application should get called. What is the command which I should put in the command prompt to close my application in such a way.
I am making an application that processes multiple files (typically > 500) through a command prompt call. The way I start the command prompt app is by looping using a call to CreateProcess for each file that is to be processed. It works fine, except that I somehow loose 'connection' to my app so that
1: Windows says that the app. is 'Not Responding' 2: The Cprogress bar in my app is not updated before all files have been processed, even though there is a CreateProcess call and a Cprogress.StepIt() from the app for each file that needs processing.
I somehow suspect that the CPU gets swamped... I do not want that Windows starts to say that my app is 'not responding' and I want my Cprogress dialog bar to update according to the number of files that are progressed through.
I wonder if multithreading is the OK way to go instead of just kicking of series of CreateProcess calls? Maybe my CreateProcess is not ending correctly? It seems as if my app is 'not regaining control' before very late. The app never crashes though.
My CreateProcess code is listed below, maybe there can be a problem with it, or maybe I should do things in a different way? My app basicaly works as it never crashes, but with above mentioned problems it is NOT a pro solution...
void CMultiFilerDlg::ProcessFile(CString pdfFile) { int i=0; DWORD ProcID; // Open file in text mode: STARTUPINFO si; PROCESS_INFORMATION pi; char cmdArgs[2052];
I am facing a problem in C++,I want to execute a command in Command prompt from a specific path.I am able o select a path and execute cmd.exe using the function ShellExecute but the problem is after selecting the path I am not able to execute the command, the command is appearing on another command prompt.
I am looking to make a program for C++ that has a GUI other than command prompt. The program I am trying to create will ask certain questions and display the results at the end after all questions are asked and have 2 copies of the results one over the other that can be printed as a receipt. Basically I am wondering can I do this using C++. Also I want another GUI other than command prompt as well. Something close to what windows uses if possible.
Im writing program for a rail fence cipher that should run from the command prompt and take in two .txt files, one containing the key for how many rails there should be (between 1 and 25) and the other containing the message to be encrypted. Both of those txt files should be entered from the command prompt, taken in with the program's arguments, not asking the user for input I think I have the logistics of how to get the program to encrypt it worked out, but every time I try to run the program it keeps on crashing.
The program should run when I enter this:./railcipher samplekey.txt samplemessage.txt
I'm pretty sure my issue lies within my first few lines of code, with the main(), or with the FILE*, but I dont know what I would need to change it to for it to work properly.
Code: #include<stdio.h> #include<string.h> #include <stdlib.h> int main(int argc, char **argv[])
If I compile code which uses cin using the command prompt, then run the compiled program a new window opens when it reaches the cin line of code, for the input. If there is no cin used then all printing happens in the original window. Is there a way to stop this behavior of the opening of a new window?
I am having a problem with my c++ code. I am attempting to clear the text off of the command prompt screen in a text based game program. I put a restart option using a goto in my program. How would I be able to clear all previously displayed text.
Code: cout << "Put in the names of people, press q to exit" << ' '; while((cin >> people_inp) && (people_inp != "q")){ Person *p = newPerson(people_inp);
[Code] ....
The problem of this code is when you put in the names(via cin) and press enter command prompt will disappear. What should I do so that Command prompt will not disappear after I input some names? I mean it disappears without you pressing a key.
How can I send information and receive from external command prompt from my program??. I want to run an external command prompt, a code that's is not mine, to send information to this command prompt, then make my program hit enter at the command prompt and then receive back information from the command prompt.
I have had experience in programming from python (slightly related, html/css) and the computercraft from minecraff (basic i think it is).
My question is mainly about the C and past experience with the computercraft.
1. Is it possible to split the command console into 2 parts (a visual area and a text area) 2. Is it possible to use any form of pixel art or custom characters within any command console using C.
I have a question about to run an MFC dialog based C++ application from console: if I run my application from console, I see the application start and the console immediately back to prompt. I need that console wait the application exit before show me the prompt again. I tried on Visual Studio 6, 2005 and 2010 but the behavior is the same.
I'm thinking of making a horror text-based game, which would use sounds, if you could also tell me of an API to display images in an alternate window that would be nice.
I am stuck in visual studio 2010 file I/O ... i placed file1 file2 using the following program under VS2010/projects/projectname/file, file1 and also in debug also once......I am actually using cmd line arguments in debug mode
Code: // feof files.cpp : Defines the entry point for the console application. //
#include "stdafx.h" #include<stdio.h> #include<stdlib.h> #include<conio.h> int main(int argc, char* argv[])
[Code] ....
I dont think in C++ forum the printf will do any problem...when i run the program it says "cannot open source file" and a window appears saying"Debug assertion failed"....and other details such as Expressionstream!=NULL).perror
