Packaging Values in Dword

Question

How would I package two unsigned short (WORD) values into one unsigned long (DWORD) value?

I know how to get them using HIWORD and LOWORD macros but is there a ... sort of reverse macro for storing them into a DWORD quickly?

I'm programming in C++ with Microsoft Visual Studio 2012 IDE.

Accepted Answer

MAKELONG takes two WORDs and combines them into a single DWORD:

DWORD MAKELONG(
  WORD wLow,
  WORD wHigh
);

No idea why it isn't called MAKEDWORD...

Answer 2

Something like:

 DWORD x = (lo) | (hi << 16);

should do it.

Answer 3

What about this MAKELONG macro?

DWORD MAKELONG(
  WORD wLow,
  WORD wHigh
);
