Question

如何读取两个页面字段值的值并将其存储到INI文件中？我使用ISTool在INI部分创建了两个密钥对。现在我如何将其链接起来？

INI部分如下所示：

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

页面是这样创建的：

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

编辑：

我做了以下补充。它由于某种原因不起作用：

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

这应该有效：

; Script generated by the Inno Setup Script Wizard.

[Setup]
; NOTE: The value of AppId uniquely identifies this application.
; Do not use the same AppId value in installers for other applications.
; (To generate a new GUID, click Tools | Generate GUID inside the IDE.)
AppId={{82C8C949-44A8-49C4-8CED-8DD0ACD0DCCF}
AppName=My Program
AppVerName=My Program 1.5
AppPublisher=My Company, Inc.
AppPublisherURL=http://www.example.com/

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


[code]
var
AuthPage : TInputQueryWizardPage;

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

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

function GetUserName(Param: String): string;
begin
result := AuthPage.Values[0];
end;

function GetPassword(Param: String): string;
begin
result := AuthPage.Values[1];
end;

Answer 2

使用[INI]部分条目中的scripted constant：

[INI]
Filename: {app}\prefs.ini; Section: AUTH; Key: USERNAME; String: {code:GetAuth|0}
Filename: {app}\prefs.ini; Section: AUTH; Key: PASSWORD; String: {code:GetAuth|1}

[Code]

var
  AuthPage: TInputQueryWizardPage;

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

function GetAuth(Param: String): string;
begin
  Result := AuthPage.Values[StrToInt(Param)];
end;

如果将用户输入的值转换为INI文件条目的逻辑很复杂，您可能更愿意使用[Code]部分中的SetIniString。通常来自CurStepChanged事件函数：

procedure CurStepChanged(CurStep: TSetupStep);
var
  IniFileName: string;
begin
  if CurStep = ssPostInstall then
  begin
    IniFileName := ExpandConstant('{app}\prefs.ini');
    SetIniString('AUTH', 'USERNAME', AuthPage.Values[0], IniFileName);
    SetIniString('AUTH', 'PASSWORD', AuthPage.Values[1], IniFileName);
  end;
end;

Answer 3

我认为您需要编写ExpandConstant('{app}\prefs.ini')来扩展{app}常量。
