Crash on Mousewheel scroll 64-bit

Hello,

the problem occurs on a 64-bit system if you scroll down in the editControl via the mousewheel.
We using a hack to prevent the division by 0 but the bug should be fixed in the syncfusion api.
We just want to inform you because this bug is now occuring for a longer time.

Our hack fix:
Public Class ScrollWheelFilter
    Implements IMessageFilter

    Public Const WM_MOUSEWHEEL As Integer = &H20A
    Public Const MK_CONTROL As Integer = &H8

    <SecurityPermission(SecurityAction.LinkDemand, Flags:=SecurityPermissionFlag.UnmanagedCode)> _
    Public Function PreFilterMessage(ByRef m As System.Windows.Forms.Message) As Boolean Implements System.Windows.Forms.IMessageFilter.PreFilterMessage
        If m.Msg = WM_MOUSEWHEEL Then
            Dim wParamLong = m.WParam.ToInt64
            If wParamLong > Integer.MaxValue Or wParamLong < Integer.MinValue Then
                Return True
            End If
        End If
        Return False
    End Function
End Class

The error seems to happen because intptr is a 64bit type.

Hi Christian, 
 
Thank you for contacting Syncfusion support. 
 
We hope reported behavior as bug. Since it reproducing in 64-bit Operating System alone, a support incident has been created under your account to track this requirement. Please log on to our support website to check for further updates. 
 
 
Regards, 
 
Kannan
