How to distinguish syslink?

[Gintaras]

Function dlg_link

Code:

Copy      Help

\Dialog_Editor

;SysLink control.
;The control shows text with links that can open web pages, files, or execute any other code.
;Link click notifications can be received in two ways:
;;;The easy way: In recent QM versions, if the link does not have id/href attributes, on click the dialog procedure receives WM_COMMAND message where wParam is link control id and lParam is 0-based index of the link in that control.
;;;The standard way: In any QM version, on click the dialog procedure receives WM_NOTIFY message with code NM_CLICK. It then can get link control id, link index and link attribute text. More info in MSDN Library.
