May 20, 2013
I want to execute one command using batch file but non of below code is working. Following are codes for executing batch file, First trial:-
STARTUPINFO si;
PROCESS_INFORMATION pi;
ZeroMemory( &si, sizeof(si) );
si.cb = sizeof(si);
ZeroMemory( &pi, sizeof(pi) );
if( !CreateProcess( NULL,
"cmd /C sa.bat",
[Code]....
Non of above code is working for me but when open same batch file using double click it work like I expected.

I'm working on a project that's got a lot of moving parts, from feedback from a position sensor to real-time video editing. The script that runs the sensor is in C++, and the API for the video editing software (vMIX) is executed with HTTP protocol. I'm hoping to use that C++ script to control the video software (as some of the editing is dependent on particular feedback from the sensor), and wanted to see how to execute a HTTP command from a C++ script.

I am trying to use a combination of windows batch scripts as well a C++ program to put users data into one single .CSV file. Right now, I have a batch file that will output data from the command line into multiple .txt files. These files are mac.txt, serialnumber.txt, computermodel.txt, and computer name.txt. What I want to do, is to have users run the batch file, which will in turn run the .exe C++ file which will concatenate all their data into one file, computerinfo.csv. The file format for this file would be to have the mac address, serialnumber, computer model, and computer name all in their own column.
My main issue is that these individual files don't have the format that I would like, but based on the command prompt functions, there isn't really any good format. For example, the mac.txt file has the following format:
Physical Address Transport Name
=================== ==========================================================
xx-xx-xx-xx-xx-xx DeviceTcpip_{xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx}
yy-yy-yy-yy-yy-yy Media disconnected
zz-zz-zz-zz-zz-zz Media disconnected
but all I really want is xx-xx-xx-xx-xx-xx
The other files have other issues with format, but if I can figure out this one then the others should be a piece of cake.
Also, I want the output of this to all go in one row, and as other users run this file, they will go into new rows without touching the rows above.

I'm creating simple console application using Code::Blocks to allow me to pass parameters from other application to replace string within text/registry file before execute the registry merge. Passing parameters to console already success. Now I only have problem with reading file. Example of first line in the registry file is as below.
Windows Registry Editor Version 5.00
However when read into string and output to console using 'cout', it will be show as below with spaces in between.
W i n d o w s R e g i s t r y E d i t o r V e r s i o n 5 . 0 0
Below is my code.
ifstream f("install.reg");
string s((istreambuf_iterator<char>(f)), istreambuf_iterator<char>());
cout << s;

I'm trying to read in a file specified in the command line but I'm having some trouble. The command line entry specifies the inputfile preceded by '<' and the output file preceded by '>' like so
./program -v < input_file.cmd > output_file.cmd
This is what I've got so far.
int main(int argc,char* argv[]){
string strv="-v";
string input="<";
string output=">";
string str;
string input_file;
const char* in=input_file.c_str();
[Code] .....
This compiles ok, but when i run it using :
./program -v < test1.cmd
I get a segfault, if i cout argc it returns '2' where i would expect for this command line entry, I 'd get 4.
I'm not yet outputting to file, just to the screen so im not specifying an output file yet.

I'm currently working on making a program that is run through a GUI run through the command line. The program basically takes an app file and a boot file and runs it through a bunch of functions and generates a new outfile. Anyway I'm new to C and can't figure out how to code it so I can type the two file paths into the command line and read them into the function. Is it possible to do this within the "if else" statement?
Code:
int main(int argc, char *argv[]){
const char * const SrcFilePath;
const char * const SRecordPath;
const char * const FopIspFilePath;

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[])

I'm working on windows and I'd like to know how to compile the C file to a different path.
What I mean is : the basic compile command is :gcc Hello.c -o Hello_E
I'd like to create the "hello_E" in a different path.Something like this:
gcc Hello.c -o C:Program FilesPellesCC_programsExe_filesHello_E

i would like to read the content of a text file data.txt (line by line ) directly from the command line using this command: a.exe < data.txt.
What could be the c++ code to read/get the content of these lines (without using ifstream). The treatment of the lines is not a problem for me but i really don't know how to access the content of the file from the c++ code

I am using stat command to check the existence of a file in a directory.
The directory is having some 10K files. I feel the stat() call is expensive as i do not need the structure to be populated.
I want only the existence of the file.
Is there any other alternative faster way to do this in C.

My program takes in an input file from the command line and converts the string from the file into a linked list and then depending on the command it will manipulate the string to either reverse the list, print the list, or take a character out...I'm having trouble taking a character out, my code compiles fine but doesn't change the string at all
Code:
#include <stdio.h>
#include <stdlib.h>
#define SIZE 1024

I have code that creates an index file created from a data file of records.
#include <iostream>
#include <fstream>
#include <map>
#include <sstream>
#include <string>
#include <iomanip>
using namespace std;
class Record {
[Code]...
I now need to write a second program that allows the user to enter a command on the Linux command line such as
search 12382 prog5.idx
and returns the information for the record with that key. The code I included for the index file is correct and works properly, but how to write the second program.
Here is the index file created by the first program:
8: blank 0 $ 0.00
12165: Item16 30 $ 7.69
12345: Item06 45 $ 14.20
12382: Item09 62 $ 41.37
12434: Item04 21 $ 17.30
16541: Item12 21 $ 9.99
21212: Itme31 19 $ 8.35
34186: Item25 18 $ 17.75
41742: Item14 55 $ 12.36
The top line is a dummy record, the first number is the size of the file.

Actually the below program is for Dispersal Algorithm called Rabin-IDA; this algorithm divided the data into N pieces and then recombine it from M pieces (such that M<N).
Thus, the below program needs command line arguments,which entering by Project properties/Debugging. this argument is file name, where the program performing spitted the file into N files, and then recombine it from M divided files, and put it on another file which should also passing its name as argument .
Now my question is, How can i make this program enter the file name by keyboard??(i mean enter the files name by user from screen not as command line arguments) ... In another word, How I can exchange ?
Code:
argc == 3
and
Code:
argc == 2
To enter file name ? i mean what i should do to in
Code:
rabin.split(argv[1])
To pass my file name by use keyboard not Project properties/Debugging?)
the below code is just the main function of program, and the whole of it in this link [URL] .... Information Dispersal Algorithms Rabin-IDA.
Code:
#include "include.h"
void __cdecl _tmain(int argc, TCHAR *argv[]) {
DWORD ini=GetTickCount();
try {
if( argc == 3 ) //recombine
[Code] ....
I know I should use getline() function but how exchange argv[] ?

Is it possible to write a program such that it will automatically execute the function in queue base on their priority even if user programmed it randomly?
Code:
function1(){ very_important; }
function2(){ important; }
function3(){ less_important; }
int main() { // Programmed by user
function3;
function1;
function2;
//Output: Program will execute function1, 2 and lastly 3.
}

For easier debugging, I would like to execute an own (predefined) function while beeing in a breakpoint (e.g. print some variables to a file).
Does there exists such a feature?
e.g.
- run program to a breakpoint
- a) press a keyboard-function-key (which calls that predefined function)
- b) or hover with cursor over a variable (and modify somehow the routine which shows its content on the screen)?

i need to create an small windows form, with some buttons, and then those buttons will "exectute" an action on a remote webserver.
Im searching with http requestings and didn't find nothing useful for what i need.
The basic thing is that i just need to press "EXECUTE" and then c# will press one link in the Webserver. I do not need any feedback from the page. I just need that C# execute a link like localhost/startbackup.php then the actions from the startbackup.php will run.
I do not need any information regarding if the page was successful executed or not, or even if it opens one window. Nothing.

I'm wondering whether it's possible to implement MPI to execute a process in parallel from deep within a C++ solution.
I've created a solution on VS2005 that links to several static libraries, and within one of these libraries there is a set series of tasks that require execution many times - they're independent so I'd like them to execute them using MPI if possible to speed up the run time.
The pseudo-code is:
Code:
for(i = 0; i < n; i++) // n is number of times to execute process {
PerformTask(data[i]); // perform the tasks required for each iteration of process
}
So, instead of conducting the tasks within PerformTask() in series n times, I want to split the array data between multiple processes such that they can each be allocated an even proportion of data to perform the tasks on. Pretty textbook reason for wanting MPI, right?
Now, I've read up and understood the basics of MPI implementation, but all the examples I've seen are called within the main() function of the program. But I need to do all this from within a static library, is this possible?
I've made some early attempts at implementing this, but get an error indicating the process wasn't initialised: "Error encounted before initializing MPICH", which I assumed would be due to trying to make the MPI calls outside of the main() function.

I have a condition and I would like to instead change the condition so that it would execute the previous statements after else statement.
It seems hard to explain but I'll try my best to illustrate anyway
if (condition)
<statement1>
else
<statement2>
So I would like to change the condition so that
if (condition)
<statement2>
else
<statement1>
And the condition is
Code:
if(!lightStateAtNextLink || !bIsLightEnAtConnection && nLinkNext.IndexToAttachedNode() != pVeh->_.stAutopilot.m_dwNextNode || bIsLightEnAtConnection && nLinkNext.IndexToAttachedNode() == pVeh->_.stAutopilot.m_dwNextNode)
And I have changed that to this. Is this correct?
Code: if(lightStateAtNextLink && bIsLightEnAtConnection || nLinkNext.IndexToAttachedNode() == pVeh->_.stAutopilot.m_dwNextNode && !bIsLightEnAtConnection || nLinkNext.IndexToAttachedNode() != pVeh->_.stAutopilot.m_dwNextNode)
