Save Inno Setup Custom Form field values to an INI file

Question

Hi,

How do I read and store the values of two form field values to an INI file? I created two key pairs at the INI section using ISTool. Now how do I link this up?

I am assuming I should write some Pascal script in here, but don't know exactly what, yet

{ AuthForm_NextkButtonClick }

function AuthForm_NextButtonClick(Page: TWizardPage): Boolean;
begin
  Result := True;
end;

The INI Section looks like this:

[INI]
Filename: {app}\prefs.ini; Section: AUTH; Key: USERNAME; String: 
Filename: {app}\prefs.ini; Section: AUTH; Key: PASSWORD; String: 

Page is created like this:

  AuthPage := CreateInputQueryPage(wpWelcome,
    'Account Information', 'Please enter your Account Information',
    '');
  AuthPage.Add('Username:', False);
  AuthPage.Add('Password:', True);

EDIT:

I made the following additions. It doesn't work for some reason:

SetIniString('AUTH', 'USERNAME', AuthPage.Values[0], '{app}\prefs.ini')
SetIniString('AUTH', 'PASSWORD', AuthPage.Values[1], '{app}\prefs.ini')

Answer 1

I believe you need to write ExpandConstant('{app}\prefs.ini') to expand the {app} constant.

This should work:
