I wan't to open a file, if it is a dropped shortcut from the WIN95-Explorer.
At the moment I receive a file namend xxxx.lnk. I think I could use IShellLink.
I found examples how to create a shortcut, but none to resolve it.
If a *.lnk is dropped, I want to know the path and filename to which it points to.

Hi volkerloges,

I use a free component that manipulates shortcuts. Yes, it creates shortcuts, but also READS it, with a ... Read method and properties that give you all the information about the source of the link. simple like that:

  PBShellLink1.FileName := OpenDialog1.FileName;
  PBShellLink1.Read;
  Edit1.Text := PBShellLink1.Description;
  Edit2.Text := PBShellLink1.WorkingDir;
  Edit3.Text := PBShellLink1.Target; //<<< This is the one

It's freeware and the source code is included. Give it a try:

IHTH,
Itamar

Hello itamar,

thank you for your answer.
Unfortunately the recommended files doesn't contain any information about how to 'resolve' a shortcut. I think about that automatic Dialog that opened, if the file the shortcut points to was moved. Do you have any information how to do a resolve?

Hi Volker,

You mean a lost shortcut, i.e., if someone moves a sorce file from the original path that was set in shortcut ? No way !!!

The dialog you mentioned must be launched by YOUR application when it cannot open the target file !

It will be just a warning with a Open dialog option to the user find the file himself, and/or a procedure that will search the entire Hard-disk(s). There is nothing else. Believe me !

Tell me if you want some help with this dialog !

Bye,
Itamar

hello itamar,
after fiddling with the source you mentionend earlier, i found
a simple solution: psl.resolve(Application.Handle, SLR_UPDATE)
does the job. BTW: The Source works also for older Delphi
releases and because of this fact is loaded with code for that
releases. With Delphi 3, the resolve function fits in 82 lines.
Thank your for your comments.
