How can I create a txt file with Inno Setup?

Question

How can I create a txt file in a folder with Inno Setup?

[Run]
SaveStringToFile('c:\filename.txt', #13#10 + 'the string' + #13#10, True);

The code doesn't work, what's the problem here?

Answer 1

You need to call the code (SaveStringToFile) from an event function or possibly from a UI-control handler. You didn't specify when you want the file to be created. Assuming you want to create it as part of the installation, you can use CurStepChanged event function in ssInstall (pre-install) or ssPostInstall steps.

[Code]
procedure CurStepChanged(CurStep: TSetupStep);
begin
  if Step = ssPostInstall then
  begin
    SaveStringToFile('c:\filename.txt', #13#10 + 'the string' + #13#10, True);
  end;
end;

Though hard-coding C: drive seems like a bad idea.
