通过Inno Setup中的任务启动自定义代码 [英] Launch custom code via tasks in Inno Setup

问题描述

如果用户在安装过程中选中了相应的复选框，我想执行一些代码.通过阅读帮助文件，看来使用该任务的唯一方法是将其与Files/Icons/etc中的条目相关联.部分.我真的很想将它与Code部分中的过程相关联.可以这样做吗?如果可以，怎么办?

I want to execute some code if a user checks a corresponding checkbox during the install. From reading the help file, it looks like the only way to use the task is to associate it with an entry in the Files/Icons/etc. section. I'd really like to associate it with a procedure in the Code section. Can this be done and if so, how?

推荐答案

您可以通过添加一个具有复选框的自定义向导页面来执行此操作，并在用户单击下一步"时为所有选中的复选框执行代码.在该页面上:

You do that by adding a custom wizard page that has check boxes, and execute the code for all selected check boxes when the user clicks "Next" on that page:

[Code]
var
  ActionPage: TInputOptionWizardPage;
  
procedure InitializeWizard;
begin
  ActionPage := CreateInputOptionPage(wpReady,
    'Optional Actions Test', 'Which actions should be performed?',
    'Please select all optional actions you want to be performed, then click Next.',
    False, False);
    
  ActionPage.Add('Action 1');
  ActionPage.Add('Action 2');
  ActionPage.Add('Action 3');
  
  ActionPage.Values[0] := True;
  ActionPage.Values[1] := False;
  ActionPage.Values[2] := False;
end;

function NextButtonClick(CurPageID: Integer): Boolean;
begin
  Result := True;
  if CurPageID = ActionPage.ID then begin
    if ActionPage.Values[0] then
      MsgBox('Action 1', mbInformation, MB_OK);
    if ActionPage.Values[1] then
      MsgBox('Action 2', mbInformation, MB_OK);
    if ActionPage.Values[2] then
      MsgBox('Action 3', mbInformation, MB_OK);
  end;
end;

这些复选框可以是标准控件，也可以是列表框中的项目，有关详细信息，请参见Pascal Scripting上的Inno Setup文档.

The check boxes can either be standard controls or items in a list box, see the Inno Setup documentation on Pascal Scripting for details.

如果要根据是否选择了某个组件或任务来执行代码，请改用WizardIsComponentSelected()和WizardIsTaskSelected()函数.

If you want your code to be executed depending on whether a certain component or task has been selected, then use the WizardIsComponentSelected() and WizardIsTaskSelected() functions instead.
