hi,

i get Event from Form this Way

PROCEDURE Main()
   CREATE EVENT PROCNAME Main_Event() HWND Form_1.HANDLE STOREINDEX nIndex

Code: Select all

PROCEDURE Main_Event()
LOCAL nHWnd   := EventHWND()
LOCAL nMsg    := EventMSG()
LOCAL nWParam := EventWPARAM()
LOCAL nLParam := EventLPARAM()

   DO CASE
      CASE nMsg = WM_HSCROLL
      CASE nMsg = WM_MOUSEWHEEL

---

under 32 Bit i got both Event but under 64 bit WM_MOUSEWHEEL seems to increase / decrease "Speaker Volume"

what might be the Difference of 32 Bit vs 64 Bit in this Situation

got it

have to do with Mouse Settings

Click mouse and touchpad settings.

In devices highlight 'mouse and touchpad' settings if not already.

Next turn off "scroll inactive windows when I hover over them"

This should fix mouse scroll issues.
