I looked around for a while. I'm going to use SendInput now. It works.

If the file is in the same directory couldn't you just do this?

#include <conio.h>
#include <fstream>
#include <iostream>
#include <string>
using namespace std;

int main(int argc, char* argv[])
{
string FileName;
cout << "Enter the file name: ";
cin >> FileName;

cout << endl << endl;

ifstream in(FileName.c_str());
while (!in.eof())
{
char ch;
in.get(ch);
cout << ch;
}
getch();
return 0;
}

Example:
Enter the file name: Stuff.txt

Stuff.

Never mind. I found out how to do it. Thanks anyway.

Hi, how would I use mouse_event to simulate the mouse wheel? I can only do clicks.

void Left_Click(const long x, const long y)
{
    mouse_event(MOUSEEVENTF_LEFTDOWN, x, y, 0, 0);
    mouse_event(MOUSEEVENTF_LEFTUP,x,y,0,0);
}
void Right_Click(const long x, const long y)
{
    mouse_event(MOUSEEVENTF_RIGHTDOWN, x, y, 0, 0);
    mouse_event(MOUSEEVENTF_RIGHTUP, x, y, 0, 0);
}

Hi, I need a way to see if a mouse button is up or down, if the wheel is being used, and if so, which direction the wheel is moving using a hook or something like that. MSDN didn't help me much. Also, I'm using Dev-C++ 4.9.9.2.:yawn:

This is a little long, but it works!

#include <string>
      #include <iostream>
      using namespace std;
      
      int main()
      {
      string word1, word2, word3;
      
      cout << "Enter word1: " <<endl;
      cin >>word1;
      cout <<"Enter word2: " <<endl;
      cin >>word2;
      cout << "Enter word3: " <<endl;
      cin >>word3;

      int Longest, Shortest;
      
      // Get the longest word 
      if (word1.length() > word2.length() && word1.length() > word3.length())
      {
      Longest = 1;
      cout << "\nLongest word: " << word1;
      }
      if (word2.length() > word1.length() && word2.length() > word3.length())
      {
      Longest = 2;
      cout << "\nLongest word: " << word2;
      }
      if (word3.length() > word1.length() && word3.length() > word2.length())
      {
      Longest = 3;
      cout << "\nLongest word: " << word3;
      }
      
      // Get the shortest word
      if (word1.length() < word2.length() && word1.length() < word3.length())
      {
      Shortest = 1;
      cout << "\nShortest word: " << word1;
      }
      if (word2.length() < word1.length() && word2.length() < word3.length())
      {
      Shortest = 2;
      cout << "\nShortest word: " << word2;
      }
      if (word3.length() < word1.length() && word3.length() < word2.length())
      {
      Shortest = 3;
      cout << "\nShortest word: " << word3;
      }
      
      // Get the word in the middle
      if (Shortest == 1 && Longest == 2)
      {
      cout << "\nOther word: " << word3;

Hi, i need to make a very large char array (char array[10000000]). How would I do this without getting a stack overflow error?

That works perfectly! Thank you.

Thanks, I'll revise my code and try it.

Hi i have been making two programs: one that sends a file's filebuf made into a char*, and another that receives that and writes it to a file. They're like exe sending programs. I can send the char* and write it onto the console using cout.write(), but when I try to copy it onto a file, it will only be like 3 bytes in size while the original file is 500kb. How would I write it correctly? I don't want to show all of my code because that would take up space, and most of it is irrelevant. I will just show the sending, receiving, and writing.

Sending:

ifstream in(FileName,ios::binary);

if (in)
    {
    filebuf *pbuf;
    pbuf = in.rdbuf();
    long size;
    size = pbuf->pubseekoff(0,ios::end,ios::in);
    char * buffer;
    buffer = new char[size];
    pbuf->pubseekpos(0,ios::in);
    pbuf->sgetn(buffer,size);
    if (send(sClient, buffer, strlen(buffer), 0) != SOCKET_ERROR)
    {
    cout << "\nSent file successfully!";
    }
    else
    {
    cout << "\nError sending file!\n";
    }
    }

Receiving and Writing:

char cClientMessage[500000];
recv(sClient, cClientMessage, 499999, 0);

ofstream out(TempFileName.c_str(), ios::binary);
string ConfirmString;
    if (out)
    {
    out.write(cClientMessage, strlen(cClientMessage));
    ConfirmString = "Successfully copied file! New file name is ";
    ConfirmString += TempFileName;
    out.close();
    }
    else
    {
    ConfirmString = "Error copying file!";
    }  
    send(sClient, ConfirmString.c_str(), ConfirmString.length(), 0);
    }

I just looked it up on google. It said it was a "Bell Character" or something like that.

Hi, I have a question: What is the mysterious beep on a console program? I made a program that reads a *.exe file then displays it on the screen. I got a massive amount of beeps! Another example of a mysterious beep is: Open Command Prompt, Press Ctrl+G, then hit enter. It will beep? Why does this happen and how can I make it stop?

Thanks!

Hi, I made a simple program that copies files. I tried to copy an exe file, but after I tried to run the copied version, it doesn't work properly. Please help:?:

Here's the code for the test file to copy:

#include <iostream>

int main()
{
    std::cout << "Hello!";
    std::cin.get();
    return 0;
}

And the copier:

#include <fstream>
#include <conio.h>
#include <iostream>
#include <string>
using namespace std;

int main()
{
    string OldFile, NewFile, OldContents;
    cout << "Enter file to copy: ";
    cin >> OldFile;
    cout << "\nEnter a new file name: ";
    cin >> NewFile;
    
    ifstream in(OldFile.c_str(),ios::binary);
    if (!in) return 0;
    
    char temp[100000] = {0};
    
    in.read(temp, 100000);
    
    OldContents = temp;
    in.close();
    
    cout << "\nDone reading!";
    ofstream out(NewFile.c_str(), ios::binary);
    
    if (!out) return 0;
    
    out.write(OldContents.c_str(), OldContents.length());
    
    cout << "\nSuccessfully copied file!";
    getch();
    return 0;
}

Thanks, that helps a lot! =)

Ok, how would I put the date at the end of the *.exe file? I want it to bee as secure as possible. I have heard of a lot of programs that can decode a hash, so I don't want to use the registry or a file.

How would I store it in the *.exe file?

Hello, I have been wondering how to keep a value even after a program ends. An example could be a countdown of days on a trial of a product. It must be able to not be changed by the user. How would I do this?

Hi, i'm finally able to respond. I have a 2.50 mghz Intel Celeron CPU 479 mb ram. I am using Dev-C++ 4.9.9.2. Ill make the loop shorter, but how long does it need to be?

I have made someyhing like this before.
Here it is:

bool CheckPrime(unsigned long num)
{
     unsigned long long int x = 2;
     bool prime;
     
     if (num < 4)
     {
     switch (num)
     {
     case 1:
     prime = false;
     break;
     
     case 2:
     prime = true;
     break;
     
     case 3:
     prime = true;
     break;
     
     case 4:
     prime = false;
     break;
     }
     }
     
     else
     {
while (x < (num / 2) + 1)
{
      if (num % x == 0)
      {
      prime = false;
      break;
      }
      else 
      {
      prime = true;
      x++;
      }
}
      }

return prime;
}

Hi, I have been making a program that searches in another process's memory for a value from the user. It works, but it's very slow. I have used other searchers like TSearch that are really fast. If anyone has a way to make it faster, please help.:-/

Here's my code

#include <windows.h>
#include <iostream>
using namespace std;

int Memory(HWND MyWindow, int long Address, int Value, bool _w)
{
    DWORD PROC_ID;
    HANDLE PROC_HANDLE;

    GetWindowThreadProcessId(MyWindow, &PROC_ID);
    PROC_HANDLE = OpenProcess(PROCESS_ALL_ACCESS, false, PROC_ID);
    if(_w)
        WriteProcessMemory(PROC_HANDLE, (LPVOID)Address, &Value, sizeof(long int), NULL);
    else
        ReadProcessMemory(PROC_HANDLE, (LPVOID)Address, &Value, sizeof(long int), NULL);
    CloseHandle(PROC_HANDLE);
    return Value;
}

int main()
{
    SetConsoleTitle("Memory Search");
    unsigned long long int x;
    LPVOID MyLPVOID;
    
    char Caption[1000];
    cout << "Enter the caption of the window: ";
    cin.getline(Caption, 1000);
    HWND Test = FindWindow(NULL, Caption);
    if (!Test)
    {
    cout << "\nCannot find window \"" << Caption << "\"!";
    cin.get();
    return 0;
    }
    
    LPVOID Address;
    cout << "\nEnter the address to start at: ";
    cin >> Address;
    
    int WhatToFind;

    cout << "\nWhat number are you trying to find: ";
    cin >> WhatToFind;
    
    for (x = 0; x < 2000000000; x++)
    {
    int AtAddress = Memory(Test, ((int long)Address + x), 0, false);
    if (AtAddress == WhatToFind)
    {
    cout << "\n\nFound it at address: " << (LPVOID)((int long)Address + x);
    cin.ignore();
    cin.ignore();
    }
    }
    cout << "\nDone!";
    cin.ignore();
    cin.ignore();
    return 0;

I have Dial-up so i have no router and my gateway is myself and sry for replying so long, i had to go

Hi, i have been making a server for a client I made to connect to. I don't have a static IP, so I need a way for someone on another computer to connect to me without me telling the user what it is every time.
I have tried to just enter another IP in the inet_addr() funtion but then it can't bind.

Please Help...:confused:

SOCKET sServer;
	sServer = socket(AF_INET, SOCK_STREAM, IPPROTO_TCP);
	if(sServer == INVALID_SOCKET || iError == 1){
		MessageBox(NULL, (LPCTSTR)"Invalid Socket!", (LPCTSTR)"Server::Error", MB_OK|MB_ICONERROR);
		WSACleanup();
		return 0;
}

SOCKADDR_IN sinServer;
	memset(&sinServer, 0, sizeof(sinServer));
	sinServer.sin_family = AF_INET;
	sinServer.sin_addr.s_addr = inet_addr("127.0.0.1"); // Where to start server?
	sinServer.sin_port = htons(1000); // Port 

if(bind(sServer, (LPSOCKADDR)&sinServer, sizeof(sinServer)) == SOCKET_ERROR){
		/* failed at starting server */
		MessageBox(NULL, (LPCTSTR)"Could not bind the server!", (LPCTSTR)"Server::Error", MB_OK|MB_ICONERROR);
		WSACleanup();
		return 0;
}

Could anyone tell me if there is a function like the InputBox() function in Visual basic? I have googled it and come up with nothing. Thanks.

Hi again, i'm making a macro building pogram. I have got mouse movement down, but now i have no idea how to do mouse clicks or keyboard input. Please help! I'm also using dev-c++ 4.9.9.2.

}
else if (MousePoint.x < 100)
{
std::ofstream SaveFile(FileName, ios::app);
SaveFile << "00" << MousePoint.x;
SaveFile.close(); …

OH!, I figured it out!!! thanks everyone, nowi got it.

whoops! Mine doesn't work either!
I dont know what to do now.........

Thank you all for your help!!

I made my own code based on your idea though.

it's right here:

#include <iostream>
using namespace std;

int main()
{
       int factor1, factor2;    
       bool prime = true;   
       cout << "Enter a number";
       int num;
       int x=2;
       char stopchar;
       cin >> num;

while (x < (num / 2) + 1)
{
      if (num % x == 0)
      {
      prime = false;
      }
      else 
      {
      prime = true;
      }
      cout << x;
      x++;
}
switch (prime)
{
       case true:
       cout << "it's prime";
       break;
       case false:
            cout << "it's not!";
            break;
}
cin >> stopchar;
       return 32;
       }

Why make your code so complicated? The most basic concept of finding prime is to test from 2 until number-1. Once you find the divisor number of that number, then you are also able to find the factor of that number.

int factor1, factor2;
    bool prime = true;
    for(int i=2; i<num; i++) {
        if (num%i==0) {
            prime = false;
            factor1 = i;
            factor2 = num/i;
            break;
    }

To improve the proformence speed, you don't need to test from 2 to number-1; you can simply test it until number/2

bool prime = true;
    temp = num/2;
    for(int i=2; i<=temp; i++) {
        if (num%i==0) {
            prime = false;
            factor1 = i;
            factor2 = num/i;
            break;
    }

To improve even more proformence speed, you can test it only test it until sqrt(number).

bool prime = true;
    temp = sqrt(temp);
    for(int i=2; i<=temp; i++) {
        if (num%i==0) {
            prime = false;
            factor1 = i;
            factor2 = num/i;
            break;
    }

I just tried that.
Whenever i entered an odd number, it said it was prime.....
Maybe it's just me or someting, but it didn't work

Thanks, and sorry for getting back so long, I had to go.

I have been making a prime number generator.
It works, but it's considerably slow if a user enters a high number. If anyone has any suggestions on how to make it faster, please post it.

Here's the genrator code:

unsigned long int theNumber;
unsigned long int Factor1 = 1, Factor2 = 1;

//-----------Find the prime number-----------------
  do
  {
  Factor2 = 1;
  Factor1 += 1;
  
  if (Factor1 * Factor2 != theNumber)
  {
  isPrime = FALSE;
  } // End if
  else
  {
  isPrime = TRUE;
  } // End else
  
  while (Factor1 < (theNumber / 2) + 1 && Factor2 < theNumber && Factor1 * Factor2 != theNumber)
  {
  Factor2++;
  
  if (Factor1 * Factor2 != theNumber)
  {
  isPrime = FALSE;
  } // End if
  else
  {
  isPrime = TRUE;
  } // End else
  
  } // End while
  } while (Factor1 * Factor2 != theNumber); // End do
  //-------------------Done finding------------------
  
  // Display the results
  switch (isPrime)
  {
  case TRUE:
  cout << "\n Hurray! It's a Prime Number!";
  break;
  
  case FALSE:
  cout << "\n Sorry, It's Not a Prime Number.\nThe two factors we found were: " << Factor1 << " and " << Factor2 << ".";
  break;
  } // End switch

oops nvm

Apparently my code has smileys in it. ifnore tham plz

Hi, i have been making a program that tests a computer owner's firewall. It gets input from the client i made, and does a system() with it. Is there any way to make the firewall not block the program right when i make a scocket?
Oh, im using Dev-C++ 4.9.9.2 also.
