i wan't to get the mouse position when i receive a WM_RBUTTONDOWN message in
VB. To do that in C++ i can use the LOWORD and HIWORD functions to retrieve
the low-order/high-order word from the lparam value. Is there any equivalent
function to LOWORD/HIWORD in Visual Basic.

Tony...

There are essentially two ways to do this -- with pure VB code, and with API
calls. I'll show both methods:

Pure VB:

Public Function LOWORD(lValue As Long) As Integer
If (lValue And &HFFFF&) > &H7FFF Then
   LOWORD = (lValue And &HFFFF&) - &H10000
Else
   LOWORD = lValue And &HFFFF&
End If
End Function

Public Function HIWORD(lValue As Long) As Integer
HIWORD = (lValue And &HFFFF0000) \ &H10000
End Function

With API:

Private Declare Sub CopyMemory Lib _
 "kernel32" Alias "RtlMoveMemory" _
 (Destination As Any, Source As Any, _
 ByVal Length As Long)

Public Function LOWORD(ByVal LongIn As Long) As Integer
Call CopyMemory(LOWORD, LongIn, 2)
End Function

Public Function HIWORD(ByVal LongIn As Long) As Integer
Call CopyMemory(HIWORD, ByVal (VarPtr(LongIn) + 2), 2)
End Function
