I have:
int _tmain(int argc, char* argv[])
{
printf("drive name: %s
", argv[1]);
It displays only the first character of the first argument on the command line.
Yet the following works as expected:
static char* myArg[2] = {"first arg","second arg"};
printf("drive name: %s
", myArgv[1]);
That displays the entire string "second arg".
So what's wrong with my reference to argv[1]?
I have this piece of code that causes segmentation fault:
Code: .... check argv[2] exists ....
std::string* op_file;
...
std::cout << "argv[2] is: " << argv[2] << std::endl;
op_file = new std::string(argv[2]);
...
The result I am getting is:
Code: argv[2] is: somefile.txt
Segmentation fault (core dumped)
How to open my two files with argv[1] and argv[2] as the parameters . Heres my code:

I have written a program to calculate delay between nodes using link.
Code:
//sim.cc
#include<stdlib.h>
#include <iostream>
#include <fstream>
#include <math.h>
#include <cstdio>
int main(int argc, char* argv[]) {
[Code] ....
then I compiled it as follows
g++ -o sim sim.cc
when i run $./sim 2 5
it gives packet delay is 0.0
where is the error?

I mainly code plugins for Cinema 4D .... I used to code in COFFEE (a javascript like language, only for Cinema 4D) and python. But, recently, I started coding in C++.
I start my development on a Mac, using Xcode. But then, to generate Windows versions of my plugins, I take my source code to Visual Studio, perform the necessary adjustments, and create Win32 and Win64 code.
Lately, I was trying to devise a scheme to protect my plugins from being pirated. Yes, I know it is virtually impossible, but if I could make it harder for hackers to crack my plugins, it would be fine.
I made it work fine in python and in C++, but only in Xcode.
In Windows it is difficult. I only need to be able to access a username/password protected folder in my server and check if there is a file there. I don't even need to read the content of the file (but it would be nice to be able to do that too).
I started out using the cURL library but it is so complicated to make it work. I need 32 and 64 bit versions. Then I also have to include three .dll files in the folder of the application (that means that I would have to ask to the people who buy my plugins to copy three additional files to the main application folder... not a good thing )
So, any way to access a username/password protected folder on the net? (the username/password is generated in my code so, of course, I know what are the username/password to provide).
Also, I would need a way for the code to be completely self-contained, meaning that the users would not have to manually add any other files (libraries), besides the folder containing my plugin.
I have been given a task to debug a C++ project. I have not written a single line of code in this project!!
This project executes for about 5 minutes without problem. Then it ends with an exception "Unhandled exception at (some .dll name) in EITos.exe: 0xC0000005: Access violation reading location "
Now every time I execute the program. The error is from a different dll. Sometimes it is a dll created by other programmers, sometimes it is related to QT. So I don't think this is a code problem. Is there any project setting that would affect this?
I am trying to use PCA, but it gives memory access violation error. Here is my sample code.

I tried installing Java Accesss Bridge for a few hours now. But with no success. The installer from ORACLE does not work (rolls back at the end without error message). Many tries of patching some libs together failed.
What do I need for an application that makes use of JAB. Do I really need some sort of installation or can I simply put some headers and libs together?

I have written a class "FileSet " in program's Document class.
This class contains other Four classes as
"Machine1" , "Machine2", "Machine 3" and "Machine 4".
Now my problem is Machine 1 can not access variables from Document class or other variables from FileSet.
How to access them ?
I'm trying to make an application for ELM327 trouble code scanning device for my own educational purpose. Most of my app code is done. however, I am stuck at one point. And I need finding relationship between two hex strings.
I have logged some communication between ECU and a chinese code scanning device for carrying out car's fuel pressure test. However there is one message (that is sent from the user side) that keeps on changing each time which is dependent upon the last message received from the ECU which is also varying every time.
Code:
RECEIVED (07E8) SEND (07E0)
05 67 03 0C 17 6A 00 00 05 27 04 8F 45 37 00 00
05 67 03 0C DB 68 00 00 05 27 04 B0 70 6B 00 00
05 67 03 10 3B 87 00 00 05 27 04 3B BC 10 00 00
[code]....
as it can be seen 3 bytes are always changing with each test, both, in the message received from the ECU, and the one sent back to the ECU from the diagnostic scanner. Trying to figure out relationship between these two strings?
P.S: about 16 million combinations for 3 byte data are possible... there must be some link between them...

I want to make a funny and simple game in cmd with visual studio and here is my plan, here are the steps that I wanna accomplish:
The program asks the person for
1: 4 girl names
2: 4 boy names
3: What they do? (4 actions)
4: Where they do this? (4 locations)
5: Random linked things
And from here I want to randomly get 1 line of a random girl name + random boy name + random action + random place. and followed by the second, third, and fourth line of random chosen things.
Like this:
Girl 1 - Boy 3 - Action 2 - Location 4;
Girl 3 - Boy 4 - Action 4 - Location 1;
Girl 2 - Boy 1 - Action 3 - Location 3;
Girl 4 - Boy 2 - Action 1 - Location 2;
And it can get funny like: Amber and John are jumping from a bridge. a game where you can play with your friends and have fun.
Here is my code so far:
#include<iostream>
#include<string>
#include<ctime>
#include<cstdlib>
int main (void) {

And from here I don't know what to do!!
I need to be able to disable the items on a CCheckListBox but I can't change the code that calls AddString. I know I can use the CCheckListBox::Enable function to disable an item if I have an index but I don't have the index which would be provided by AddString.
I've tried intercepting the LB_ADDSTRING message and then looping through the items in the control but the string has not been added at this point so the last item in the list is never disabled.
I used Spy++ to see what messages were being sent and I noticed that LB_GETTEXT was sent so I tried intercepting this message (ugly hack) but this caused my app to hang - I assume because of the number of times the message is sent. Is there a way to disable the items?
I would like to copy one bmp file to another using plain fstream (none 3-rd party library). I've managed to come up with something but I keep getting error:
Unhandled exception at 0x504A3442 (msvcr120d.dll) in ConsoleApplication1.exe: 0xC0000005: Access violation reading location 0x00380000.
when i try to write the content of the bmp files not the header, namely error occurs in this line:
Code : ofs_differential.write((char*)&picture, (bfh_warm.bfSize - bfh_warm.bfOffBits));
Also i am not sure if i am doing it in a right way, meaning that even after solving this error i will copy the bmp file successfully.
Code:
// ConsoleApplication1.cpp : Defines the entry point for the console application.
//
#include "stdafx.h"
#include <iostream>
#include <fstream>
using namespace std;
struct BITMAPfileHEADER {
unsigned short bfType;
