C :: Program For Infinitely Looping After And Testing For Active Process
Mar 23, 2013
What I have: A basic program for infinitely looping after and testing for an active process. It has a delay system built in to make it so it is not constantly iterating.
What I need: A way to get process IDs from other Processes other than my program. With a way to use that ID to detect if that process is active on the computer or not.
Parts of my code that need changing:
/* Code for handling the process would go here */
/* Code for detecting the target would go here */
What the goal of my program is: Perform operations to terminate the process of cmd.exe when it is active on the user's computer. Then output the status of the process and the time it took to find that process to the user.
It contained functions that I needed, but I need more information on how to apply them to other processes instead of the parent of my program and its' children.
Here is the code I prewrote for this so far:
Code:
#include <stdio.h>
#include <stdlib.h>
#include <time.h>
#define ZERO 0
#define INFINITE 1000000000000000
[Code] .....

Why this program keeps looping infinitely when i run it and try to put some input...
#include <iostream>
#include <iomanip>
#include <cstring>
#include <string>
using namespace std;
struct Account {
[Code] ....

You are to create a program using nested looping. Your program is to have a menu asking the user to select which pattern to create and how many rows to use (it should accept 1 to 10 rows and keep the aspect ratio of the pattern). The patterns are 1 - Box, 2 - V, 3 - Inverted V. Note, if I select pattern 1 with 10 rows, the box will have 10 asterisks in the first row.
Okay so i came up with the box but i have been getting stuck at getting the V or inverted V.

You pros are once newbies like us. Hoped you might take a little time sharing your expertise. Got freaked out when our teacher gave us this activity, where she haven't taught this to us yet. So this is the activity (LOOPING) :
Write a program that accepts a positive integer. The program should be the same from the given output. Use do while to allow the user to continue or not.
OUTPUT must be:
n = 5
0
1==0
2==1==0
3==2==1==0
4==3==2==1==0
5==4==3==2==1==0
if n = 6
0
1==0
2==1==0
3==2==1==0
4==3==2==1==0
5==4==3==2==1==0
6==5==4==3==2==1==0

I have a program that I can only run one instance of. When I try to start it a second time, it doesn't do anything. I would like to create a script that loads the program in a way that I can run multiple instances. Since I assume the program checks the process tree on startup to see if an other instance is already running, I figure disabling access to the process tree could do the trick.

I am trying to create a program that would execute a foreground process. I have this code for the foreground process
Code:
#include <stdio.h>
#include <signal.h>
int main() {
int temp;
printf("We are in the current program
[Code] ....
And this is my main program
Code:
#include <unistd.h>
#include <signal.h>
#include <stdio.h>
int main() {
signal(SIGINT, SIG_IGN);
[Code] ....
My main program stops executing after the process "./scanf" executes and there fore does not print the line "How are You"...
I want to main program to continue executing after "./scanf" finishes. How to achieve that?

I have a logined user and my running program as system process (not user process).
I want to get user name and surname from AD.
1. GetUserName() dont useful becouse it gets name for current process owner(for SYSTEM in my case).
2. There are userLogin, userName, userSurname and userDisplayedName in user properties of AD. Its possible to get userDisplayedName by NetUserGetInfo(), but
I want to know is it possible to get userName and userSurname?

how to get a list of the active processes on a computer?
What I need to do is check for a specific process to see if it's running on the system.
I just need to know if a certain process is present.

I have a general question on Call Stack of Embedded uCs.
The Call Stack should include all the Active Sub-routines.
For example, in the following sequence:
Func 1 Starts -- Call Func2 --> Func 2 Starts -- Call Func3 --> Func 3 Starts --> YOU ARE HERE
The Stack should include the Return Addresses of Func 2's Body and Func 1's Body, Right?
At any certain moment (e.g. when the uC experiencing a SW Bug), Is it possible to have the uC to get all the Active Sub-Routines from the Stack and print them (e.g. for knowing it at the moment of Bug)?
It'd debug failures, when I don't work with a Debugger.
I know that Debuggers do that - i.e. show you the Call Stack at each moment - So I am wondering if I can get the uC to to it for me every time a bug occurs.

I can select the textbox #2 text with this.
this.tB2.Click += new System.EventHandler(tB2_Click);
private void tB2_Click(object sender, System.EventArgs e) {
tB2.SelectAll();
}
What would be the simplest way to do the same for all textboxes on the form, preferably on both click and enter events.

I have a DLL developed using pure VC++ (all unmanaged code that doesn't use .NET framework). This DLL will be deployed in different client PCs within a network and will act like an agent.
Now I have establish a communication between this DLL and a WCF web service, that will be deployed in a server PC. The Service will first get a list of PCs either name or IP Address within a network using LDAP (Active Directory) and once, we get the PCs, I have to establish a communication between the web service and the agents that reside in these client PCs,
How can I accomplish this?

Say I have something lke
Code:
#define FOO BAR
#if FOO == BAR
doX();
#else
doY();
#endif
This causes doX(); to be executed. But the intent is to have doY(); be run. I'm guessing this is because BAR is undefined and therefore blank, so blank equals blank. Is there some way to compare the symbol FOO was set to instead of its value, BAR?

In the below program, when we have 4 consecutive spaces, the following comparison will not be equal: (x / tabstop != (x + spaces) / tabstop). If we have, let's say, only 2 consecutive spaces, then the comparison will be equal. So we know to print a tab with 4 consecutive spaces and not print a tab otherwise. How do we know this kind of division comparison would work in every case?
#include <stdio.h>
#define TABSTOP 4
int main(void) {
size_t spaces = 0;
int ch;
size_t x = 0; /* position in the line */
size_t tabstop = TABSTOP; /* get this from the command-line

I developed this simple sample program to test cos():
Code:
#include <cmath>
#include <iostream>
using namespace std;
int main() {
const float radiansToDegrees = 180.0f / 3.141592653589793f;
float c = sqrt(2.0f);
float a = 1;
float angleRadians = cos(a/c);
float angle = radiansToDegrees*angleRadians;
}
I expected angle to be 45 exactly, but it's value is: angle = 43.558804
Why is the angle not 45 degrees? What did I do wrong?

I'm working on collision detection for a game in SFML. I successfully designed a Spatial Partition grid to speed up the collision test, in the following of this tutorial: [URL] ....
But now I have an issue with one aspect of it: Going through a vector of objects and testing all the OTHER objects in the vector against said object. The author puts it into psueudocode here:
For each tick of the clock
For every object in the game
Get all the other objects in the same grid square
For each other object in the same grid square
I have trouble with the last line, because in iterating through a vector I am not sure how to skip over the current object. Here is my own code (a couple of sysntax errors but this is a c++ question not an SFML question):
//for every moveable object
for(int i = 0; i < rects_.size(); i++){
std::vector<sf::RectangleShape> posibleObjects_; //this will be a vector of WorldObjects in a real game
//for every object in that object's gridsquare
for(int j = 0; j < rects_.size(); j++){
if(rects_[i].intersects(rects_[j])){
//collision
} } }
The problem is, a collision will always be reported because somewhere in the vector the object will eventually check against itself which is always a true collision. What is the correct way to do this?

I am checking to see if two references are bound to the same object. My instincts tell Me, "Check their addresses. If they match, they are bound to the same." At the same time, I have not found anything in the C++ standard which would support this approach. Am I missing something? Is there wording which backs up My instincts? Is there a standard function to do this?

I have a text file with state names, and state abbreviations, thusly:
ALASKA
AK
ARKANSAS
AR
..and so on.
I have to load the abbreviations ONLY from the file into an array of char[ - (already done and tested).
I have to get a 2 char abbreviation as a string,then test it against the state array to make sure it is a valid abbreviation. As it stands, my test is never finding an invalid abbreviation..
Here is where I get the input:
void getState() {
char state[10];
getString("Please enter the state as a 2 char abbreviation:",state,10);
printf("State Entered:%s", state);
validState(state);

I was wondering what function was the C++ equivalent for testing to see if a user input is numeric.
I have equivalents in Ruby, Java, Python, VB, VBA, php, but being a novice in C++, I have yet to find one - even with Google.
And I know C++ is such a wonderful language, that its extensive library must have one somewhere - considering it's already 2013!
