我正在编写一个脚本,要求用户选择要安装的应用程序的哪些部分：
仅限应用程序,仅限DataBase Engine,仅限数据或这些的任意组合.
我知道我应该使用[Components]部分来定义这些,但是我对类型,组件和任务之间的相互作用感到困惑 – 首先,我认为[Tasks]是为了“额外”安装,但后来我看到了代码明确地链接三个.
谁能指点我对这些如何协同工作的一个很好的解释？ – 我相信有一个……
谢谢

组件由一种或多种类型组成.在脚本中,您将使用组件作为选择器,具体取决于最终用户选择的类型.组件可以在任务中使用,因为根据用户选择的类型,任务将被执行或不被执行.
例如：
; 'Types': What get displayed during the setup
[Types]
Name: "full"; Description: "Full installation";
Name: "app"; Description: "Fapplication only";
Name: "dbengine"; Description: "Database engine only";
Name: "data"; Description: "Data only";
; Components are used inside the script and can be composed of a set of 'Types'
[Components]
Name: "full"; Description: "Full installation"; Types: full app dbengine app
Name: "app"; Description: "Fapplication only"; Types: app
Name: "dbengine"; Description: "Database engine only";Types: dbengine
Name: "data"; Description: "Data only"; Types: data
; Defines which files are setup,based on the differents components
[Files]
Source: "MyApp.exe"; DestDir: "{app}"; Flags: ignoreversion; Components: full app
Source: "ADll.dll"; DestDir: "{app}"; Flags: ignoreversion; Components: full app
Source: "Engine.dll"; DestDir: "{app}"; Flags: ignoreversion; Components: full dbengine
Source: "data_0"; DestDir: "{app}"; Flags: ignoreversion; Components: full data
Source: "data_1"; DestDir: "{app}"; Flags: ignoreversion; Components: full data
; In the same fashion,a task can be set for a specific component
[Tasks]
Name: desktopicon; Description: "Create a &desktop icon"; GroupDescription: "Additional icons:"; Components: full app
