[AccessD] 64 Bit Access and comdlg32.dll

[Stuart McLachlan]

You don't have Ptrsafe here:

Private Declare Function GetOpenFileName _
Lib "COMDLG32.DLL" Alias "GetOpenFileNameA" _
(pOpenfilename As OPENFILENAME) As Long

Also, you need to modify OPENFILENAME by changing LONG to LONGPTR for

hWndOwner and hInstance since they are handles.
