How I can detect if mouse is over the scrollbar?

Hi all. How I can detect if the mouse is over the scrollbar?

Thx in advance.

Using timer perhaps:

VB Code:

Option Explicit
 
Private Type RECT
   Left As Long
   Top As Long
   Right As Long
   Bottom As Long
End Type
 
Private Type POINTAPI
    X As Long
    Y As Long
End Type
 
Private Declare Function GetCursorPos Lib "user32" _
    (lpPoint As POINTAPI) As Long
 
Private Declare Function GetWindowRect Lib "user32" _
    (ByVal hwnd As Long, lpRect As RECT) As Long
 
Private Sub Form_Load()
    Timer1.Enabled = True
    Timer1.Interval = 100 '1/10 of a second
End Sub
 
Private Sub Timer1_Timer()
'==================================
Dim Rec As RECT, Point As POINTAPI
Dim cbOpen As Boolean
 
    DoEvents
    GetWindowRect HScroll1.hwnd, Rec
    GetCursorPos Point
    
    'check if cursor is over combobox
    If Point.X >= Rec.Left And Point.X <= Rec.Right And Point.Y >= Rec.Top And Point.Y <= Rec.Bottom Then
        Debug.Print "MousePointer is over Horizontal Scrollbar"
    Else
        Debug.Print "MousePointer is outside Horizontal Scrollbar"
    End If
 
End Sub
