[SHELL32]
Implement the usage of the STARTF_TITLEISLINKNAME flag (in a STARTUPINFO structure, it
signals that the program was started from a shell link, and therefore its lpTitle member
holds the path of the link).
What I do is that, in CShellLink::InvokeCommand (called when a shortcut is being
executed), I initialize the SHELLEXECUTEINFO structure such that we know that we are
starting from a shortcut (use the
SEE_MASK_HASLINKNAME flag), and to hold the path to the flag I use its lpClass member
(which is not used for other things in this code path). Then the whole thing is passed to
ShellExecuteExW which, in turn,
calls the SHELL_ExecuteW function. This function reads the SHELLEXECUTEINFO structure and,
if it has the flag SEE_MASK_HASLINKNAME (or SEE_MASK_HASTITLE too, if somebody also uses
lpClass to pass a particular
title for the startup), we use the forementioned lpClass member, holding the link path, as
the title (lpTitle member) of a new STARTUPINFO object used when calling CreateProcess
(and thus, launching the
new application). So that this application will be aware that she was launched via a link
(therefore we become compliant with the STARTF_TITLEISLINKNAME documentation).
