hey

for sum reason when i run my program it doesnt work as expected.

this is what i do.
1.load cursor co ords from txt file.
2.set cursor pos (to the ones from the file) and right click.

unfortuantly it doesnt do what i want it to, it doesnt move to the correct cursor position. it just goes to the top left hand of my monitor.

heres my code


Code:
#include <iostream>
#include <tchar.h>
#include <fstream>
#include "stdafx.h"
using namespace std;

DWORD SCP = (DWORD)GetProcAddress(LoadLibraryW(L"user32.dll"), "SetCursorPos") + 5;

__declspec(naked) BOOL WINAPI SetCursorPosX(int X, int Y)
{
   __asm
   {
      push   ebp
      mov    ebp, esp
      jmp    dword ptr [SCP]
   }
}

DWORD PMA = (DWORD)GetProcAddress(LoadLibraryW(L"user32.dll"), "PostMessageA") + 5;

__declspec(naked) BOOL WINAPI PostMessageX(HWND hWnd, UINT Msg, WPARAM wParam, LPARAM lParam)
{
   __asm
   {
      push   ebp
      mov    ebp, esp
      jmp    dword ptr [PMA]
   }
}

int righ[3];//r

HWND MuWndt = FindWindow("MU", NULL);
void load()
{

   ////////////right click
   ifstream toad("dw_dk.txt");
   int yucky;
   int rats = 0;
   while(toad >> yucky)
   {
      righ[rats] = yucky;
      rats++;
   }
}


int zop = 0;
DWORD WINAPI rightclick(LPVOID)
{
   if(zop == 0)
   {
      zop = 1;
      int i;
      while(1)
      {
         SetCursorPosX(righ[0], righ[1]);
         Sleep(100);
         PostMessageX(MuWndt, WM_RBUTTONDOWN, NULL, MAKELPARAM(righ[0], righ[1]));
         for(i = 0; i < 1000; i++)//100000
         {
            Sleep(10);
             if(GetAsyncKeyState(VK_NUMPAD2) || GetAsyncKeyState(VK_NUMPAD0) & 0x8000)
             {
               zop = 0;
               PostMessageX(MuWndt, WM_RBUTTONUP, NULL, MAKELPARAM(righ[0], righ[1]));
               return 0;
            }
         }
         PostMessageX(MuWndt, WM_RBUTTONUP, NULL, MAKELPARAM(righ[0], righ[1]));
         Sleep(1500);
         SetCursorPosX(righ[2], righ[3]);
         Sleep(500);
      }
   }
   return 0;
}

int main()
{
   load();
   while(1)
   {
      Sleep(10);
      if(GetAsyncKeyState(VK_NUMPAD2))
      {
         CreateThread( NULL, 0, (LPTHREAD_START_ROUTINE)&rightclick, 0, 0, NULL);
      }
          }

return 0;
}


thanks for any help!!!

You have to convert the strings to integers.

it's declared as an int though isnt it?

in the line
Code:
int righ[3];//r


because an int cannot store a string?

thanks

You assigned a string into an integer.

Edit: Oh, you used the >> operator... so I guess the the coordinates in the text file are incorrect.

Oh, my bad, I didn't see you used the >> operator.

Well, you tried reading righ[3] which is out of the array bounds, that's your first mistake.
Also check that the coordinates are correct, try debugging.

thats fine

all of the co ords printed fine.

i wasnt sure if it was being converted properly like u said about the string stuff, and i thought that was the reason it isnt working properly. but i really have no clue :/

Your array size is only 3 and you're accessing the 4th cell (righ[3]), so if all the coordinates are correct it means you read more than 3 integers - index is out of range.

And what's SetCursorPosX? some hooked function? maybe the problem is in there.

yeh i fixed teh array stuff,still isnt working

heres setcursorposx and postmessagex


Code:
DWORD SCP = (DWORD)GetProcAddress(LoadLibraryW(L"user32.dll"), "SetCursorPos") + 5;

__declspec(naked) BOOL WINAPI SetCursorPosX(int X, int Y)
{
   __asm
   {
      push   ebp
      mov    ebp, esp
      jmp    dword ptr [SCP]
   }
}

DWORD PMA = (DWORD)GetProcAddress(LoadLibraryW(L"user32.dll"), "PostMessageA") + 5;

__declspec(naked) BOOL WINAPI PostMessageX(HWND hWnd, UINT Msg, WPARAM wParam, LPARAM lParam)
{
   __asm
   {
      push   ebp
      mov    ebp, esp
      jmp    dword ptr [PMA]
   }
}
