Window Notify NMHDR\idFrom

[mk-soft]

If gadgets are created with #PB_Any, the wrong DialogID is entered, so the wrong IdFrom comes in the Notify NMHDR.

With X64 this is 64bit.

The issue occurs because Windows uses the GetDlgCtrlID function to obtain the control ID value, and its return value is always a 4-byte integer.
If a valid 64-bit ID value is set when a gadget is created, it is not a bug in PB.
Therefore, there is no general solution, and you must use a workaround as shown below.

Code: Select all

*hdr.NMHDR = lParam
Gadget = GetWindowLongPtr_(*hdr\hwndFrom, #GWLP_ID)
; Is it a valid PB gadget?
If GadgetID(Gadget) = *hdr\hwndFrom
  ...
EndIf
