forms - InnoSetup : Is it possible to open my custom Delphi form (from the DLL) instead of the standard setup wizard

Question

我需要使用自己的组件(有点像 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中，这个DLL将可供InnoSetup进程使用。

这就是我尝试这样做的方法:

Delphi DLL代码

library OneClickWizard;

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

{$R *.res}

exports
  CreateWizardForm,
  DestroyWizardForm;

begin
end.

德尔菲形式

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。似乎它超出了主消息周期。如何正确执行此操作？

在我的设置中我做了类似的事情。InnoSetup 代码我将句柄传递为 StrToInt(ExpandConstant('{wizardhwnd}')) (我的猜测是 MainForm.Handle 为零)

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;
