lCustData property

Pointer<NativeType> lCustData
getter/setter pair

Application-defined data that the system passes to the hook procedure identified by the lpfnHook member. When the system sends the WM_INITDIALOG message to the hook procedure, the message's lParam parameter is a pointer to the OPENFILENAME structure specified when the dialog box was created. The hook procedure can use this pointer to get the lCustData value.

Implementation

external Pointer lCustData;
