Forwaring mousewheel Messages

[Ben Reese]

Hello all

When a DataGrid has the focus moving the mouse wheel will scroll the DataGrid.
this does not happen (unsuprisingly) when some control other than the
datagrid has the focus.
However I would like the DataGrid to scroll with the mouse wheel regardless
of which control has the focus. I can obviously trap a mouse wheel event on
the form or the datagrid but i cannot see a way to programatically scroll the
datagrid.

I thought I might be able to intercept mouseWeel messages in WndProc and
forward them as scroll messages onto the datagrid but I cannot make this work.
I have overriden wndProc in my form and in an inherited version of the
DataGrid in an attempt to work out which message makes it scroll, but there
are too many and i can't see the wood for the trees.

Is there a resorce I can get (like the API Text viewer in VB6) with a
comprehensive list of message constants or is there a better way to do this
anyway?
Thanks
Ben
