#include <windows.h>
#include <iostream>

using namespace std;

int main()


{
		cout << "Hello World"; 
	

HKEY hKey;


	// The path of your exe file. If you have a long path, 
	// change the number of elements in the array.  
	unsigned char PathToFile[100]="C:\\Users\\dhayalan\\Desktop\\junk\\clco.exe";

	
	// The directory of registry to be opened.
	//RegOpenKeyEx(HKEY_LOCAL_MACHINE,"Software\\Microsoft\\Windows\\CurrentVersion\\Run",0,	KEY_SET_VALUE,&hKey );

	
	// Set the Value which iHKEY hKey ; 
    DWORD disp ; 
    DWORD createError = RegCreateKeyEx( 
        HKEY_LOCAL_MACHINE,   // handle of an open key 
        "Software\\Microsoft\\Windows\\CurrentVersion\\Run",   // subkey name 
        0,          // reserved 
        NULL,       // class string 
        REG_OPTION_NON_VOLATILE, // permanent entry 
        KEY_READ | KEY_WRITE,   // desired security access 
        NULL,       // security attributes (default) 
        &hKey,     // handle for opened key returned 
        &disp ) ;   // created new vs. opened existing 
    if ( createError == ERROR_SUCCESS ) 
    { 
        // now can use hKey in other APIs 
    } 
    else 
    { 
        // createError is an error code which can be looked up 
        // in WINERROR.H or fed into FormatMessage. 
    } 
//directory of your exe file. 
	RegSetValueEx(hKey, "hello world",0,REG_SZ,PathToFile,sizeof(PathToFile));

	
	//Close key.
	RegCloseKey(hKey);
