Dear Jimmy,

Please use hb_retnl() (and hb_retnll()) instead of hb_retni()

YES, that work without Warning

---

Question :
now i have hb_retnll() for 64 Bit and 32 Bit and it also seems to work under 32 Bit ... do i need to change it :?:

normal ListView_GetSelectedCount() or ListView_GetSelectionMark() will not have a "big" Number ...

Jimmy

Dear Jimmy,

You can safely use hb_retnll() in 32 bits
