Re: How to control another program to run cryptically?

thanks for your help
I'v installed a global hook in a DLL(SetWindowsHookEx(WH_CBT, CBTProc,
g_hInstDLL, 0)),this is the callback function:
LRESULT CALLBACK CBTProc(int nCode, WPARAM wParam, LPARAM lParam)
{
   FILE* stream;
 TCHAR sFilename[MAX_PATH]={0};
 int n_count;
  int pos=-2;
    LPCBT_CREATEWND p=(LPCBT_CREATEWND)lParam;
 if(nCode==HCBT_CREATEWND)
 {
     DWORD m_PID;
     HANDLE m_handle;
  GetWindowThreadProcessId((HWND)wParam,&m_PID);
  m_handle=OpenProcess(PROCESS_ALL_ACCESS, TRUE, m_PID);
  n_count=GetModuleFileNameEx((HMODULE)m_handle,NULL,sFilename,MAX_PATH);
  CloseHandle(m_handle);
  pos = strcmp( &sFilename[n_count-12], "AcroRd32.exe" );
  if(pos==0)
  {
   stream = fopen( "c:\\sys_fopen.txt", "at" );
  fwrite(sFilename,sizeof(char),n_count,stream);
        fclose( stream );
  }
}
I ran "AcroRd32.exe" ,then I opened "c:\\sys_fopen.txt", I found the code
above has run 44 times!
I can't understand this,and would you help me to write this code? thanks
