C# :: Running PowerShell Cmdlets From Application
Feb 26, 2015
I'm fairly new to PowerShell and I'm trying to run this command from my application to return the 25 newest entries in the application event log and save them to a file on my desktop. Here's the code. I get an Common Language Runtime error with no real information.
PowerShell ps = PowerShell.Create();
ps.AddCommand("Get-EventLog");
ps.AddArgument("application");
ps.AddParameter("Newest", 25);
ps.AddScript("Format-List > ~\Desktop\samplelog.txt");
ps.Invoke();
Here is the Method: [URL] ....
Here is the Error: [URL] ....

I 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?

For my project I need to check whether my application instance is already running or not. I got the following code from Net ..
Code :
HANDLE mutex;
mutex = CreateMutex( NULL, TRUE, _T("MYAPPNAME"));
if ( GetLastError() == ERROR_ALREADY_EXISTS ) {
// There's another instance running. What do you do?
AfxMessageBox(_T("Application Already Exists"));
PostQuitMessage(0);
ExitThread(0);
return;
}
The code works fine .. but the code even works fine , even if I pass any string as a parameter to CreateMutex. E.g.
mutex = CreateMutex( NULL, TRUE, _T("QQQQ"));
How it is working fine ?

I'm trying to simulate a ctrl+ keypress into a running application.
Code:
#include <stdio.h>
int main (void) {
system("/usr/local/bin/rundb");
}
My problem is that the rundb program needs the user to type ctrl-b then s to actually start executing. What is the best way to handle this automatically? Some sort of fork/pipe?

I want to create an application that starts an application and passes input to that application. I know how to start a process using the classes in System.Diagnostics, but I don't know how to pass data to the process.
For example, and this is just an example, I would like to be able to automatically start an application that requires a username and password and automatically enter the username and password. Of course, that might open the door to security vulnerabilities, but that's not the point of the exercise.
How to implement the functionality I described? Is there a general way to go about doing this or does it depend entirely on the idiosyncrasies of the application in question?

I have a COM exe which runs fine on all machines that I have used except one. On a particular machine, the COM exe does not start even after trying to execute it manually (do a double click on the file from explorer).
There are no error messages as well. what could be happening ?

i 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

Giving 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?

I 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.

I need to run a program that makes a SLR Parser Table.
Here is the code :
Code to find first and follow:
saved as SLR.h
#include<stdio.h>
#include<ctype.h>
#include<conio.h>
#include<stdlib.h>
#include<string.h>
#include<iostream.h>
#define epsilon '^'
since I didn't know how to type epsilon symbol temporarily I am using ^
char prod[20][20],T[20],NT[20],c[10][10],foll[10][10],fir[10][10];
int tt,tnt,tp,a;
int follow[20][20],first[20][20];
void first_of(char);
int count(int j);
void rhs(int j);

I 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;
[Code] ....
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;
unsigned int TS;
static float slope= 0.00227272727273;
static float intercept=- 102.272727273;
static int length;
double Actual_Degree;

I 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;
}

This program is meant as practice. However, it is not working as intended. The for loop is meant to take the argument from the user and use it as the amount of times to loop. Instead it simply outputting: . It is supposed to output i++ but does not.
Here is the code:
main.cpp:
#include <iostream>
#include <stdlib.h>
int main(int main, char* arg[], char* arg2[]) {
int iterator = atoi(arg2[0]);
std::string z = "-c";

I 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?
