C :: Program To Hide Files Behind Other Files Using Alternate Data Streams
Apr 5, 2013I am writing a program to hide files behind other files using Alternate Data Streams in Windows NTFS file systems.
The program is as follows:
Code:
#include <stdio.h>
#include <stdlib.h>
int main(void){
char hostfile[75], hiddenfile[75], hiddenFileName[15] ;
printf("Enter the name(with extension) and path of the file whose behind you want to hide another file: ");
scanf("%75s", hostfile);
[Code]...
The complier is showing error as "Extra Perimeter in call to system" but I am not getting where?
C++ :: Display Last 1000 Lines From Multiple Text Files (log Files)
Jan 16, 2014I am writing a piece of code that requires me to display the last 1000 lines from a multiple text files (log files). FYI, I am running on Linux and using g++.
I have a log file from which - if it contains more than 1000 lines, I need to display the last 1000 lines. However, the log file could get rotated. So, in case where the current log file contains less than 1000 lines, I have to go to older log file and display the remaining. For e.g., if log got rotated and new log file contains 20 lines, I have to display the 980 lines from old log file + 20 from current log files.
What is the best way to do this? Even an outline algorithm will work.

C++ :: How To Prevent Loop Running Over
Feb 18, 2014i am writing a function that takes a delimited string and splits the strings into it's respective words according to the delimeter.
1) iterate through string and store delimeter position in vector array.
2) iterate through again and use substr to split into words and store again in a vector.
I then have a dictionary file, and am comapring each values in the string with each in the dictionary, problem is that it overruns the loop and obviously gives a subscript out of range error.
Code:
#include <iostream>#include <fstream>
#include <vector>
using namespace std;
//Start with string inputString
//Find delimeters ::pos as ints and stores positions in vector <int> array
//Run though string using 'find' and seperate string by positions of char32s
//Build vector<string> array of individual words in string
//Open dictionary file and loop though testing each words in vector string array against each word in dictionary

C/C++ :: Running Array In Less Complexity
Feb 9, 2015Giving a dynamic array, we want to pass the array elements from a file. The first number in the file N gives us the array length. They follow N numbers, the actual elements of the array.
Three brothers are going to work in the shop of their father for a time. The shop is doing well and every day generates profit which the three brothers may provide. The brothers agreed that they would divide the total time in three successive parts, not necessarily equal duration, and that each one will be working in the shop during one of these parts and collects the corresponding profit on his behalf. But they want to make a deal fairly, so that one received from three more profit someone else. Specifically, they want to minimize the profit the most favored of the three will receive.
I first created a program that WORKS! with complexity O(n3).
#include <stdio.h>
#include <stdlib.h>
#include <limits.h>
int sum_array(int* array, int cnt){
int res = 0;
int i;
for ( i = 0; i < cnt ; ++i)
[Code] .....
Let's assume that we have the following input:
10
1 1 8 1 1 3 4 9 5 2
The ouptut should be 15 -> A = 1 + 1 + 8 + 1 + 1 + 3 = 15 , B = 4 + 9 = 13 , C = 5 + 2 = 7.
But the ouptut is 16!
How can I reduce the complexity of my first working! C code?
C/C++ :: How To Determine If Application Is Already Running On Mac OSX
Dec 18, 2014I have a service A, and an application B. Service A needs to launch application B only if it's not running currently. This can be easily done in Windows by calling GetExitCodeProcess function. I cannot find an equivalent method for doing so in Linux/Mac.
So my current code says:
system("open /Users/adsmaster/client/client &"); // to launch the application from the service in a new shell
I read that on a Linux-line machine you can use $ cal to get the exit value of the recently run process but I am not sure how can get the exit value of a particular process?
C++ :: Monitor Cpu Usage While App Is Running
Jul 15, 2012I am working on a parallel processing server/client app with a multi-threaded server and several data processing clients, each their own process. I am trying to optimize some of the parameters, such as the size of the chunks that are read, processed, and output, and also some of the timeout values and such. I can track the time to finish a given task well enough, but it would be really nice to be able to track the cpu use. When CPU use is near 100% (on all cores) for the entire run, that is a good sign. I have noticed that with some combinations of parameters, CPU drops quite a bit for long stretches, which is not such a good sign. This app process large input files (2.5GB-65GB so far) and needs to be stable for long periods of time.
Other than sitting and staring at the task manager all day, is there a good way to track/log the CPU usage over runs that take many hours? I know that there are some apps like Everest that chart CPU use, but it would be nice to have something that would write to the same log file I am already using for other program output.

C :: Running Linear Actuator Without Feedback
Jan 4, 2014I am trying to do single axis solar tracker with linear actuator /rtc/ UNO. I have already done with feedback sensor.
Now Here I am trying to without feedback. Linear actuator specification: 24v , 3.2mm/sec as speed , 600mm stoke.
Desired angle calculation:
tracking start from 7am to 18PM, 11hours
Assumed degree: 7AM as -45 deg , 12.30 as 0 degree and 18 pm as 45 degree.
static float slope= 0.00227272727273;
static float intercept=- 102.272727273;

How can i put time here. Coding for calculating Ton time and solve above equation. below i posted my code . I need it has to be modified little bit. i need to implement ton time actuator here.
I need function takes desired and actual angle , where actuator try to move to its actual desired position.
Code below in arduino version
Code:
double Desire_Degree;

C :: Running A VBS Script Int Without Command Window
Dec 19, 2014I have created an scientific calculator application and I have a VBS script that runs some of the files. I want to create a C program that runs that VBS script. however, a command window flashes before the application opens. So basically I need a short C (or C++) program that runs a VBS script without a command window popping up. I am on Windows 8 and my compiler is GCC/G++ under cygwin. Here is what I have now that DOES NOT work.
Code:
#include <windows.h>
int main()

ShellExecute( NULL, NULL, "StartUp.vbs", NULL, NULL, SW_HIDE);
return 0;

C/C++ :: Running Multiple Terminal In Xcode
Oct 5, 2014I am using Xcode to do c++ programming and I have a c++ code, with different input arguments. I want to achieve that in Xcode, I could run multiple simultaneous running of my c++ code. However, the current problem is that once one code finishes, its terminal window automatically closed and I do not have time to look at its result. Thus computer time is wasted. Is there a way to run multiple same c++ code with different arguments input?

Aug 7, 2014I have a Class called 'DataManager' which contains a list of my 'DataItem' objects (this are created by an XML file).
I have also created some custom controls which, among other things, has a property to link it to a "DataItem" object.
My question is, is it possible to create an instance of my DataManager class at design time (which runs all the code as it would at run time to create all the DataItems from the XML)?
I want to do this so that I can update my DataItem property in my custom controls to use a UITypeEditor which then allows me to link to a DataItem at design time.
