Hi,
I have some problem. Example:
I created some exec using free pascal and lazarus. It is placed on
http server. User in webbrowser click download, and server should
attach link from where it is clicked into this exec. So when user run
downloaded exec, this exec can read this link. The idea is that
everything is in one file (and must be). My question is, exists any
commandline tool which can edit executable file for edit some resource
(like ResEdit or Restorator for Windows) which can be used by http
server? By resource I mean some const (or resourcestring section, free
pascal binary can replace it in runtime, can some tool do this same
outside?). So main problem is in server side. Finally we can use free
pascal compiler and compile modified source by server, but this
solution we use when everything fails (admins, restrictions etc.). I
need this only for windows (for now), so I'm considering some
commandline installer makers like InnoSetup or something. Any idea?
Let's see if we can get this straight. What you're basically looking for
is something which can take one or more of the environment variables (or
equivalent) that the web server knows about, and use it to "brand" the
executable.
This is probably going to be very much specific to the version of
Windows that the client is running: it used to be possible to simply
append data to an executable since there was an unambiguous file length
in the header, but this obviously won't work if the file is checksummed
or signed.
Unless you're doing it by re-linking the program when sending it to the
client, this is probably outside the remit of FPC and you'd be better
off looking for non-specific tools.
In any case, you've obviously got the problem of copying the unbranded
binary to a working area before manipulating it, unless you can
serialise the CGI or whatever you're using.
