Bit Question from a Newbie 2

[japhy]

Probably a very easy question...thanks for your patience in answering it.

I'm trying to combine two 16 bit words into 1 32 bit DWORD...the two 16 bit words are contained in unsigned ints.

which operator can combine these in this way?

Thanks very much

If you want them side by side, you need to use the left shift operator on one of them. Ex.

unsigned short one = 0x1234;
unsigned short two = 0x5678;
unsigned int combined = (one << 16) | two;
// Now combined is 0x12345678.

Option 2:

WORD one=0x1234;
WORD two=0x5678;

DWORD three;
HIWORD(three)=one;
LOWORD(three)=two;

result -> 0x12345678
