InnoSetup:是否可以打开我的自定义Delphi表单(来自DLL)而不是标准设置向导

Question

我需要使用自己的组件(有点OneClick安装程序)创建一个复杂的表单,并将其用作标准InnoSetup向导的替代品.可能吗？

我的表单被放入DLL,这个DLL将可用于InnoSetup进程.

这就是我试图这样做的方式:

Delphi DLL代码

library OneClickWizard;

uses
  SysUtils,
  Classes,
  Wizard in 'Wizard.pas' {FormWizard};

{$R *.res}

exports
  CreateWizardForm,
  DestroyWizardForm;

begin
end.

德尔福形式

unit Wizard;

interface

type
  TFormWizard = class(TForm)
  private
    { Private declarations }
  public
    { Public declarations }
  end;

var
  FormWizard: TFormWizard;

procedure CreateWizardForm(AppHandle: THandle); stdcall;
procedure DestroyWizardForm; stdcall;

implementation

{$R *.dfm}

procedure CreateWizardForm(AppHandle: THandle);
begin
  Application.Handle := AppHandle;
  FormWizard := TFormWizard.Create(Application);
  FormWizard.Show;
  FormWizard.Refresh;
end;

procedure DestroyWizardForm;
begin
  FormWizard.Free;
end;

InnoSetup脚本(iss)

[Setup]
;Disable all of the default wizard pages
DisableDirPage=yes
DisableProgramGroupPage=yes
DisableReadyMemo=true
DisableReadyPage=true
DisableStartupPrompt=true
DisableWelcomePage=true
DisableFinishedPage=true

[Files]
Source:"OneClickWizard.dll"; Flags: dontcopy

[Code]
procedure CreateWizardForm(AppHandle: Cardinal); 
  external 'CreateWizardForm@files:OneClickWizard.dll stdcall';
procedure DestroyWizardForm;
  external 'DestroyWizardForm@files:OneClickWizard.dll stdcall';


procedure InitializeWizard();
begin
  CreateWizardForm(MainForm.Handle);
end;

表单出现在屏幕上,但它对我的输入没有反应.似乎它超出了主要的消息周期.怎么做到这一点？

Answer 1

在我的设置中,我做了类似的事情.InnoSetup代码我传递句柄StrToInt(ExpandConstant('{wizardhwnd}'))(我的猜测MainForm.Handle是零)

在DLL中:

OldAppHandle := Application.Handle;
try
  Application.Handle := hAppHandle; // hAppHandle the handle from InnoSetup
  F := TfmZForm.Create(Application);
  try
    F.Caption := lpTitle;
    F.ShowModal;
    Result := F.ErrorCode;
  finally
    F.Free;
  end;
finally
  Application.Handle := OldAppHandle;
end;

我对InnoSetup一无所知,但你肯定需要使用ShowModal而不是Show here.安装UI总是模态的,你想要的是等到用户在返回Inno之前完成对表单的迭代.否则,Inno将如何知道何时继续？ShowModal运行一个消息循环来为表单提供服务,这样接收输入就没有问题了.

您还将更改您的DLL以删除DestroyWizardForm,因为调用ShowModal的函数可以创建和销毁表单.
