wParam
The high-order word indicates the distance the wheel is rotated, expressed in multiples or divisions of WHEEL_DELTA, which is 120. A positive value indicates that the wheel was rotated forward, away from the user; a negative value indicates that the wheel was rotated backward, toward the user.

How do I obtain this value?

Knowing VB, it probably uses the "and" keyword. So replace & with "and". Then use whatever VB uses to signify hex values. I think it was the # last time my friend showed me something in VB, not sure though. Just look it up with google.

Testing now.....

not working. I've tried different combinations. Help file shows Hex() statement, that didnt work either.

I get 3 digit numbers for .paramL and .paramH, and trying to add the hex number to it yields a 0

Public Type EVENTMSG
message As Long
paramL As Long
paramH As Long
time As Long
hwnd As Long
End Type

When I get a wm_mousewheel event, I copy the memory to the eventmsg structure. From what I understand I think paramH, should contain this >>>>>>>>>>>

I just got this code from microsoft forum Rolling Eyes

and don't forget to shift 16 bits to the right

I know nothing about manipulating bits/bytes/ whateva's, so i'm at the complete mercy of my lack of knowledge.

I tried this

Private Function HighWord(ByVal i As Long) As Integer
HighWord = ((i And &HFFFF0000) \ &H10000)
End Function

the variable i = 312 and the function returns 0. Something not right ...... I dont see how you can extract what I"m looking for from the number 312

just make it into one 32-bit integer and then divide by 65536, and the whole value is what you need

and yes, i=312 has as result 0

Didn't I say to use google? ...

Here, search "vb extracting high word from dword"

and get:

http://www.geocities.com/practicalvb/vb/math/words.html

as second link. It explains everything you need.

That took me 30 secs...

I see now, that the function requires a double word value for input. However the value I have from the eventmsg structure is a long. Every sample code I've found that uses this structure to capture windows events has the paramL and ParamH values as LONG.... however the structure accurately records all the wm_mouse and keyboard events correctly, except for what it seems the wm_mousewheel
