HIWORD and LOWORD equilavents

I was looking through a C++ file and saw that to find the high-order bit of a value, like wParam or lParam, they used HIWORD and to find the low-order bit they used LOWORD.

(At least, that's what I assume these functions do ;) )

I think to find the HIWORD - equivalent in VB you use &HFFFF (I'm not sure how many f's) but I don't know if this is what you use for the LOWORD, or it is the other way around or maybe you use

God this is starting to sound like an Eminem single.

Okay. How do you find the HIWORD and LOWORD of a value?

I think this is what you are looking for.

Hope it is of some help

Public Function HiWord(wParam As Long) As Integer

If wParam And &H80000000 Then
HiWord = (wParam \ 65535) - 1
Else
HiWord = wParam \ 65535
End If

End Function


Public Function LoWord(wParam As Long) As Integer

If wParam And &H8000& Then
LoWord = &H8000 Or (wParam And &H7FFF&)
Else
LoWord = wParam And &HFFFF&
End If

End Function

BTW, HIWORD and LOWORD are macros (note the capital letters - instant giveaway), and you can get at the definitions (I think they're in winbase.h).

macros, shmacros

Thanks for the help.
