to transfer more bytes from kit to pc

Hi,
i want to transfer to/from 64 bytes from kit to pc and viceversa.so i made the following changes in the code.

in HID_Client VC++ program in HIDClientDlg.cpp
the if conidtion on !HID_WRITE(); is becomes false and
executing OnError();

so herewith i'd attached the program modification. Please can anyone tell me what mistake i made or what correction/modification i need to carry.

in the USBTrace the buffer shows the value sent from kit to PC. So i think the transfer from kit to pc is ok. it is problem with receiving from pc. or problem with Device descriptor.

with regards

void CHIDClientDlg::OnSelchangeDevice()
{
  DWORD cnt;
  int   n;
/*--------

      if (!HID_Write(OutReport, sizeof(OutReport), &cnt)) {
        OnError();
        return;
      }

}
