hi:

im having some troubles with detecting pointer using my dll dialog.
i want to use MapID in maplestory to see if im inside the game or not
8824cc + 5D8 is the MapID ptr.

so here is what i did.
Code:
int ID;
ID  = *((int *) (*((unsigned long *) 0x008824cc) + 0x5D8));
SetDlgItemInt(hWnd,IDC_INPUT,value,TRUE );// print out the ID in an edit control IDC_input.


if im ingame, it works perfectly by returning the ID of my current map.
but if im in cashshop, login screen, it crashed automatically.
i thought maybe its the SetDlgItemInt that made the crash, so i take it out, but i got crashed too with just setting up the value ID.

is there anyway to detect if im ingame or at login screen without getting crashed.
cuz i remember if i add the ptr+offset in CE, it returned value ?? when im in loginscreen.
help is appreciated Razz
