CHAR name[MAX_PATH]="ET.exe";
int StatusET()
{  
	ET=NULL;
 	hSnap = CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS,0);
	ZeroMemory(&proc,sizeof(proc));
	proc.dwSize=sizeof(proc);
	if(Process32First(hSnap,&proc)){

	}	
	if(ET==NULL)
	{		
		SendMessage(lists,LB_ADDSTRING,0,(LPARAM)"ET не найден!");
		return 0; 
	}
	return 1;
}

ну и потом 

int ReadPS(int address,HANDLE HWD){
	DWORD rw;
	ZeroMemory(&buf,5);
	ReadProcessMemory(HWD,(void*)address,(void*)&buf,1,&rw);
	return 1;
}
