我已经在InnoSetup脚本的"其他任务"页面中添加了一个复选框

[Tasks]
Name: "StartMenuEntry" ; Description: "Start my app when Windows starts" ; GroupDescription: "Windows Startup"; MinVersion: 4,4; 

我希望在wpSelectTasks页面显示时初始化此复选框,并在Next单击按钮时读取值.我无法弄清楚如何访问复选框`checked'值.

function NextButtonClick(CurPageID: Integer): Boolean;

var
  SelectTasksPage : TWizardPage ;
  StartupCheckbox : TCheckbox ;

begin
Result := true ;
case CurPageID of

    wpSelectTasks :
        begin
        SelectTasksPage := PageFromID (wpSelectTasks) ;
        StartupCheckbox := TCheckbox (SelectTasksPage... { <== what goes here??? }
        StartupCheckboxState := StartupCheckbox.Checked ;
        end ;
    end ;    
end ;
