Title: FF3 - Suspicious Pointer Assignment
Post by: SeaVipe on July 17, 2019, 07:42:07 PM
Hello,


I can't get rid of the compiler warning "Suspicious Pointer Assignment" generated by the code below:


Code: [Select]

Function FRMTASKEDITOR_CUSTOM ( _
                              hWndForm      as HWnd, _      ' handle of Form
                              wMsg          as UInteger,  _  ' type of message
                              wParam        as WPARAM, _    ' first message parameter
                              lParam        as LPARAM   _   ' second message parameter
                              ) as Long
    Select Case wMsg
        Case WM_NOTIFY
            Dim lpNmh  as NMHDR Ptr
            lpNmh => lParam ' <- Suspicious Pointer assignment warning.
            ' or
            lpNmh = lParam ' <- Suspicious Pointer assignment warning.


The code works correctly but the warnings are there regardless of what I try. Researched on FB forum also.
Using this line as an example resulted in a syntax error:
Code: [Select]
LPWSTR = Cptr(LPWSTR, RT_RCDATA)
Any ideas would be helpful, thanks...
Clive

Use lpNmh = CAST(NMHDR PTR, lParam)

Works! Thanks Josť,


I tried (almost) that code previously but got an error because I didn't use PTR correctly.
