Generating PIF files

In our application we still have a lot of DOS-based applications.  These DOS-apps can be runned one after the other and in that case we have to make sure that for every EXE there's a PIF with the 'Close on exit' checkbox marked, so the DOS-window is closed when the application finishes.
PIF files made under NT don't work under 95/98, so before starting the DOS EXE we'd like to create a PIF file beside it at run time and place the checkbox 'Close on exit' marked.  Can this be done programatically???

Not with documented APIs. But you can use this one...  :-)

function CreateLink(pathObj, pathLink: string; closeOnExit: boolean) : HRESULT;
var sl : IShellLink;
    s1 : string;
  sl:=CreateComObject(CLSID_ShellLink) as IShellLink;
  result:=(sl as IPersistFile).Save(PWideChar(wideString(pathLink)),true);
  with TFileStream.Create(pathLink,fmOpenReadWrite) do
      if closeOnExit then byte(s1[$64]):=ord(s1[$64]) or       $10
      else                byte(s1[$64]):=ord(s1[$64]) and (not $10);
    finally Free end;


Regards, Madshi.

P.S: You need D3 or D4 to compile it...

But after looking on MSDN we found a more simple solution, create a _default.pif (with the 'Close on exit' checked) in de windows system directory.  This is the default

Yes, but this effects the whole system, not only your app. Don't know if your costumers like that...
