void ByteToStr(
     DWORD cb, 
     void* pv, 
     LPSTR sz)
//--------------------------------------------------------------------
// Parameters passed are:
//    pv is the array of BYTES to be converted.
//    cb is the number of BYTEs in the array.
//    sz is a pointer to the string to be returned.

{
//--------------------------------------------------------------------
//  Declare and initialize local variables.

BYTE* pb = (BYTE*) pv; // local pointer to a BYTE in the BYTE array
DWORD i;               // local loop counter
int b;                 // local variable

//--------------------------------------------------------------------
//  Begin processing loop.

for (i = 0; i<cb; i++)
