when i run the compieled .exe-file it shows the commandline, and I wish to remove it.. But I don't know nothing about C++, so I wonder how one can do it?
This is not my script... Just so you know.
#include <iostream>
#include <windows.h>

GetFunctionCount count = (GetFunctionCount) GetProcAddress(libsmart, "GetFunctionCount");
GetFunctionInfo info = (GetFunctionInfo) GetProcAddress(libsmart, "GetFunctionInfo");
int exports = count();
cout << "#Exports = " << count() << '\n';
for (int i = 0; i < exports; i++) {
char* def = new char[1024];
void* addr;
info(i,addr,def);
cout << '\t' << addr << " = " << def << '\n';
delete def;
}
cout << "Starting SMART...\n";
Setup setup = (Setup) GetProcAddress(libsmart, "std_setup");
setup((char*)"http://world19.runescape.com/", (char*)",f5", 765, 503,(char*)"");
while (true) Sleep(1000);
return 0;
}

Should work. Don't forget the definition at the top.
If you wish to remove the part that shows the commandline, any line that starts with cout << is showing something to the screen.
However, the command line is primarily stored in argv, and I don't see any reference to that in your program.
You will want to compile and link it to the windows subsystem, rather than the console subsystem.

From the console i am asking for a hexadecimal string to convert to a pointer to reference an item in memory.
#include <iostream>
#include <sstream>
#include <Windows.h>
int char_to_pointer(std::string input);
int main() {
int sample = 100; // lets say this address is 0xc1f1
std::string input_;
std::cout << "addr:" << &sample << std::endl;
std::cout << "what is the memory address?:" << std::endl;
std::cin >> input_;
unsigned int inp = char_to_pointer(input_);
std::cout << "imp: " << inp << std::endl;
Sleep(10000);
return 0;
}
int char_to_pointer(std::string input) {
return std::stoul(input, nullptr, 16);
}
My problem is that char_to_pointer only converts the hex string into a decimal.
this is what i want:
input: "0xc1f1"
output: 100
I found the solution:
#include <iostream>
#include <sstream>
#include <Windows.h>
#include <string>
int *char_to_pointer(std::string input);
int main() {
int sample = 100; // lets say this address is 0xc1f1
std::string input_;
std::cout << "addr:" << &sample << std::endl;
std::cout << "what is the memory address?:" << std::endl;
std::cin >> input_;
int *inp = char_to_pointer(input_);
std::cout << "imp: " << inp << std::endl;
std::cout << "imp*: " << *inp << std::endl;//This was my solution
std::cout << "imp&: " << &inp << std::endl;
Sleep(10000);
return 0;
}
int *char_to_pointer(std::string input) {
return (int *)std::stoul(input, nullptr, 16);
}
So I recently decided to pick up programming again and went with C++. Tried to make an adventurer class, but I seem to be running into some trouble. Here are my files:
Adventurer.h:
#ifndef __Adventurer_H_INCLUDED__ //if Adventurer.h hasn't been included yet...
#define __Adventurer_H_INCLUDED__ //#define this so the compiler knows it has been included
class Adventurer
{
private:
int hp, mp, str, agi, magic, armour;
public:
Adventurer(){}
void printStats();
}
#endif
Adventurer.cpp:
#include <iostream>
#include "Adventurer.h"
Adventurer::Adventurer()
{
hp = 50;
mp = 25;
str = 5;
agi = 5;
magic = 5;
armour = 5;
}
void Adventurer::printStats()
{
cout << "HP = " << hp << "\n\n";
cout << "MP = " << mp << "\n\n";
cout << "str = " << str << "\n\n";
cout << "agi = " << agi << "\n\n";
cout << "magic = " << magic << "\n\n";
cout << "armour = " << armour << "\n\n";
}
RPG_Game.cpp:
// my first program in C++
#include <iostream>
#include <string>
#include "Adventurer.h"
;using namespace std;
int main()
{
cout << "Hello Adventurer! What is your name? \n";
string advName;
cin >> advName;
cout << "\nYour name is " << advName << "!";
Adventurer *adv = new Adventurer();
cout << adv.printStats();
delete adv;
system(pause);
}
Let's look at the errors in your code
First, in your Adventurer.h, put a semicolon (;) after the class.
Next, in that same class, you have
Adventurer(){}
change this to
Adventurer();
Then, in your RPG_Game.cpp , change
cout << adv.printStats();
to
adv->printStats() ;
When using pointers, you need to use -> and not .
And lastly,
system(pause);
should be
system( "pause" );
Now, try running your code.
Also, you might find this helpful.
What's meaning of field uc_stack in struct ucontext_t？Who use it? The coroutine or the coroutine's signal handler? How can I test it? For example
#include <iostream>
#include <ucontext.h>
#include <queue>
#include <signal.h>
using namespace std;
void sigHandler(int signo)
{
printf("sigHandler:%x\n", &signo);
exit(-1);
}
queue<int> qProduct;
void consumer(ucontext_t* pConsumer, ucontext_t* pProducer)
{
char a[SIGSTKSZ] = {0};
while(1)
{
if(qProduct.size() > 0)
{
cout << __FUNCTION__ << "|" << qProduct.front() << endl;
qProduct.pop();
}
else
{
cout << pConsumer << "|" << pProducer << endl;
swapcontext(pConsumer, pProducer);
}
}
}
void producer(ucontext_t* pConsumer, ucontext_t* pProducer, bool* pFinished)
{
for(int i=0; i<10; i++)
{
if(qProduct.size() < 5)
{
qProduct.push(i);
cout << __FUNCTION__ << "|" << i << endl;
}
else
{
cout << pConsumer << "|P|" << pProducer << endl;
swapcontext(pProducer, pConsumer);
}
}
cout << pConsumer << "|P|" << pProducer << endl;
swapcontext(pProducer, pConsumer);
*pFinished = true;
}
int main(int argc, char* argv[])
{
ucontext_t Main, Consumer, Producer;
/* The stack for the iterator function. */
char consumer_stack[SIGSTKSZ];
char producer_stack[SIGSTKSZ];
cout << "SIGSTKSZ:" << SIGSTKSZ << endl;
/* Flag indicating that the iterator has completed. */
volatile bool bFinished = false;
getcontext(&Consumer);
Consumer.uc_link = &Main;
Consumer.uc_stack.ss_sp = consumer_stack;
Consumer.uc_stack.ss_size = sizeof(consumer_stack);
makecontext(&Consumer, (void (*)(void))consumer, 2, &Consumer, &Producer);
getcontext(&Producer);
Producer.uc_link = &Main;
Producer.uc_stack.ss_sp = producer_stack;
Producer.uc_stack.ss_size = sizeof(producer_stack);
makecontext(&Producer, (void (*)(void))producer, 3, &Consumer, &Producer, &bFinished);
if(!bFinished)
{
swapcontext(&Main, &Producer);
}
return 0;
}
Who use the stack "consumer_stack", "consumer" or "sigHandler"?How to prove it?
so i have this code for checking crc file named map.spak and compare the result with my specified crc result which stored in variable "compare"
int main(int iArg, char *sArg[])
{
char sSourceFile[MAX_PATH];
memset(sSourceFile, 0, sizeof(sSourceFile));
CCRC32 crc32;
crc32.Initialize(); //Only have to do this once.
unsigned int iCRC = 0;
strcpy(sSourceFile, "map.spak");
int compare = 399857339;
ifstream checkfile(sSourceFile);
if (checkfile){
cout << "Checking file " << sSourceFile << "..." << endl;
crc32.FileCRC(sSourceFile, &iCRC);
if(iCRC == compare){
cout << "File " << sSourceFile << " complete!\nCRC Result: " << iCRC << endl;
}else{
cout << "File " << sSourceFile << " incomplete!\nCRC Result: " << iCRC << endl;
}
}else{
cout << "File not found!" << endl;
}
system("pause");
return 0;
}
and now i want to make this code for multiple file
let's say the file name list stored in filelist.txt
the filelist.txt structure:
id|filename|specified crc
1|map.spak|399857339
2|monster.spak|274394072
how to make the crc check, loop for each file name
i'm not really good at c++ i only know some algorithm because i know PHP
c++ is too complicated
this is the full source included CRC source Source Code
or pastebin
TestApp.cpp link
I made several changes to your code. I removed guard headers since we use it only in header files. Old-fasioned memset has been replaced by operation on strings. I suspect that you need to pass char* to CCRC32 object hence sSourceFile is still const char*. I compiled code except parts with CCRC32.
#include <iostream>
#include <fstream>
#include <string>
#include <vector>
#include "../CCRC32.H"
int main(int iArg, char *sArg[])
{
std::vector<std::string> filenames;
// TODO - populate filesnames (paths?)
CCRC32 crc32;
crc32.Initialize(); //Only have to do this once.
for (unsigned int i = 0; i < filenames.size(); i++) {
const char* sSourceFile = filenames[i].c_str();
unsigned int iCRC = 0;
int compare = 399857339; // TODO - you need to change this since you are checking several files
std::ifstream checkfile(sSourceFile);
if (checkfile) {
std::cout << "Checking file " << sSourceFile << "..." << std::endl;
crc32.FileCRC(sSourceFile, &iCRC);
if(iCRC == compare){
std::cout << "File " << sSourceFile << " complete!\nCRC Result: " << iCRC << std::endl;
} else {
std::cout << "File " << sSourceFile << " incomplete!\nCRC Result: " << iCRC << std::endl;
}
} else {
std::cout << "File tidak ditemukan!" << std::endl;
}
}
return 0;
}
What do I have to do to make my program use a file that has been dragged and dropped onto its icon as a parameter?
My current main method looks like this:
int main(int argc, char* argv[])
{
if (argc != 2) {
cout << "ERROR: Wrong amount of arguments!" << endl;
cout << "\n" << "Programm closed...\n\n" << endl;
exit(1);
return 0;
}
Converter a(argv[1]);
// ...
cout << "\n" << "Programm finished...\n\n" << endl;
// cin.ignore();
return 0;
}
What I'd really like to be able to do is select 10 (or so) files, drop them onto the EXE, and process them from within my application.
EDIT:
The incomming parameter is used as filename, constructed in the cunstructor.
Converter::Converter(char* file) {
// string filename is a global variable
filename = file;
myfile.open(filename.c_str(), ios_base::in);
}
The method where the textfile gets read:
string Converter::readTextFile() {
char c;
string txt = "";
if (myfile.is_open()) {
while (!myfile.eof()) {
myfile.get(c);
txt += c;
}
} else {
error("ERROR: can't open file:", filename.c_str());
}
return txt;
}
EDIT2:
deleted
Update:
I got again to this point.
Actual Main method:
// File path as argument
int main(int argc, char* argv[]) {
if (argc < 2) {
cout
<< "ERROR: Wrong amount of arguments! Give at least one argument ...\n"
<< endl;
cout << "\n" << "Programm closed...\n\n" << endl;
cin.ignore();
exit(1);
return 0;
}
vector<string> files;
for (int g = 1; g < argc; g++) {
string s = argv[g];
string filename = "";
int pos = s.find_last_of("\\", s.size());
if (pos != -1) {
filename = s.substr(pos + 1);
cout << "argv[1] " << argv[1] << endl;
cout << "\n filename: " << filename << "\n pos: " << pos << endl;
files.push_back(filename);
}
files.push_back(s);
}
for (unsigned int k = 0; k < files.size(); k++)
{
cout << "files.at( " << k << " ): " << files.at(k).c_str() << endl;
Converter a(files.at(k).c_str());
a.getATCommandsFromCSV();
}
cout << "\n" << "Programm finished...\n\n" << endl;
cin.ignore();
return 0;
}
Actually the console window apears for maybe 0.5 sec and closes again.
It doen't stop on any of my cin.ignore(); Maybe it doesn't get there?
Can anyone help?
Your program does not need to do anything special apart from handling command-line arguments. When you drag-drop a file onto an application in Explorer it does nothing more than to pass the file name as argument to the program. Likewise for multiple files.
If all you expect is a list of file names, then just iterate over all arguments, do whatever you want with them and be done. This will work for zero to almost arbitrarily many arguments.
Maybe you could write a test program like this:
int main(int argc, char* argv[])
{
// argv[0] is not interesting, since it's just your program's path.
for (int i = 1; i < argc, ++i)
cout << "argv[" << i << "] is " << argv[i] << endl;
return 0;
}
And see what happens after you throw different files at it.
EDIT: Just look at Joey's answer.
Answer to the main question
TO SEE THE ANSWER TO YOUR LAST PROBLEM SEE BOTTOM OF THIS ANSWER
All drag&dropped files are get-able as argv[orderOfTheFile] (orderOfTheFile is from 1-n),
however how does windows create that order, now that is a real mystery...
Anyway let's say I would create 26 plain text files ( *.txt ), from a.txt to z.txt on my Desktop,
now if I would drag&dropped them on my ArgsPrinter_c++.exe located directly on C:\ drive,
an output would be similar to this:
argc = 27
argv[0] = C:\ArgsPrinter_c++.exe
argv[1] = C:\Users\MyUserName\Desktop\c.txt
argv[2] = C:\Users\MyUserName\Desktop\d.txt
argv[3] = C:\Users\MyUserName\Desktop\e.txt
argv[4] = C:\Users\MyUserName\Desktop\f.txt
argv[5] = C:\Users\MyUserName\Desktop\g.txt
argv[6] = C:\Users\MyUserName\Desktop\h.txt
argv[7] = C:\Users\MyUserName\Desktop\i.txt
argv[8] = C:\Users\MyUserName\Desktop\j.txt
argv[9] = C:\Users\MyUserName\Desktop\k.txt
argv[10] = C:\Users\MyUserName\Desktop\l.txt
argv[11] = C:\Users\MyUserName\Desktop\m.txt
argv[12] = C:\Users\MyUserName\Desktop\n.txt
argv[13] = C:\Users\MyUserName\Desktop\o.txt
argv[14] = C:\Users\MyUserName\Desktop\p.txt
argv[15] = C:\Users\MyUserName\Desktop\q.txt
argv[16] = C:\Users\MyUserName\Desktop\r.txt
argv[17] = C:\Users\MyUserName\Desktop\s.txt
argv[18] = C:\Users\MyUserName\Desktop\t.txt
argv[19] = C:\Users\MyUserName\Desktop\u.txt
argv[20] = C:\Users\MyUserName\Desktop\v.txt
argv[21] = C:\Users\MyUserName\Desktop\w.txt
argv[22] = C:\Users\MyUserName\Desktop\x.txt
argv[23] = C:\Users\MyUserName\Desktop\y.txt
argv[24] = C:\Users\MyUserName\Desktop\z.txt
argv[25] = C:\Users\MyUserName\Desktop\a.txt
argv[26] = C:\Users\MyUserName\Desktop\b.txt
My ArgsPrinter_c++.exe source code:
#include <iostream>
using namespace std;
int main(int argc, char* argv[]) {
cout << "argc = " << argc << endl;
for(int i = 0; i < argc; i++)
cout << "argv[" << i << "] = " << argv[i] << endl;
std::cin.ignore();
return 0;
}
Your last problem
I have created a simple program that creates only a sceleton of your class so it can be used, and the program's main itself ran JUST FINE => if your program exits too soon, the problem will be in your class...
Tested source code:
#include <iostream>
#include <vector>
using namespace std;
class Converter{
public:
Converter(const char* f){ cout << f << endl; }
void getATCommandsFromCSV(){ cout << "called getATCommandsFromCSV" << endl; }
};
int main(int argc, char* argv[]) {
vector<string> files;
for (int g = 1; g < argc; g++) {
string s = argv[g];
string filename = "";
int pos = s.find_last_of("\\", s.size());
if (pos != -1) {
filename = s.substr(pos + 1);
cout << "argv[1] " << argv[1] << endl;
cout << "\n filename: " << filename << "\n pos: " << pos << endl;
files.push_back(filename);
}
files.push_back(s);
}
for (unsigned int k = 0; k < files.size(); k++)
{
cout << "files.at( " << k << " ): " << files.at(k).c_str() << endl;
Converter a(files.at(k).c_str());
a.getATCommandsFromCSV();
}
cout << "\n" << "Programm finished...\n\n" << endl;
cin.ignore();
return 0;
}
