Hello,
I've made a program in Object Pascal which works ok. I was wondering if the Pascal code below could be done with newLisp. That would for me a more convenient solution for my project, that already uses newlisp.dll (see http://www.mcmusiceditor.com). Here the central part of the Pascal code that does the job (the complete code is at the end of the email). The idea: if there is no default PDF viewer, invoke MCMsumatrapdf.exe only if the loaded file is test2.pdf; otherwise show a message. Of course, if there is a default PDF viewer, then the file will be shown.
SetCurrentDirectory(pchar(ExtractFilePath(paramstr(0))));
result:=ShellExecute(0, 'open', pchar(paramstr(1)), nil, nil, SW_SHOWNORMAL);
if result = SE_ERR_NOASSOC
then
begin
(* if no duplicates as in case of calling the help file helptest2.ppx, invoke MCMsumatrapdf.exe; in other cases like View PDF show the message box *)
if paramstr(1) = 'helptest2.pdf'
then
begin
cmd:='MCMsumatrapdf.exe ';
cmd:=cmd+'"'+paramstr(1)+'"';
WinExec(pchar(cmd),SW_SHOWNORMAL);
end
else
MessageBox(0,'There is no application associated with a PDF file. ...','No PDF file association!',MB_OK or MB_ICONINFORMATION)
end
except
end;
end.
Thanks in advance.
Regards,
Reinier

Conceptually, yes, you can do this in newLISP. There is, though, the question of how much of the current functionality you want to remain in a newLISP version. For instance, I don't know what
But I also wonder that, if you (presumably) already have Sumatra PDF, why don't you just use that to open *all* PDFs?
In any case, good hacking to ya!
