制作部署安装包：Inno Setup

前一篇尝试Office 2003 VSTO的开发、部署有提到用VS开发一个简单的VSTO程序。打包C/S程序，我首先想到的是VS里自带的Setup Project。很遗憾，VS2012及后面的版本都剔除了Setup Project，改用InstallShield Limited Edition。

Setup Project配置起来N麻烦，如：配置完成了之后，一旦修改了项目的东西然后重新生成，只有移除原来定义好的快捷方式、主输出，然后重新设置才能应用修改。而ISLE，对于一些简单的打包，基本上都是满足了的，而且整个操作过程都有界面，动动鼠标就行了；里面有部分功能是可以写代码定制的，不过要授权收费！这是我个人的使用心得，安装打包用得不多，有误之处，还请多多指教。

无意中发现了Inno这个小东西（官网地址），然后深深地被它吸引了。麻雀虽小，五脏俱全，可以完全免费使用，最主要的是它允许自己使用Pascal语言编写定制脚本。

网上挺多资料的，但很多都是雷同，且测试时部分有bug。下面贴上自己的一个代码栗子，参考了网上的几篇文章，然后修改整理的。

需要注意的：

1、打包指定文件（夹）时，该文件（夹）必须存在文件，不然编译时提示错误。路径（可使用相对路径）CheckOfficeConsoleDotNetFramework必须要存在文件，可以是任何类型的。

Source: "CheckOfficeConsoleDotNetFramework*"; DestDir: "{tmp}"; Flags: ignoreversion 

2、检测.net framework，如果不存在则从指定网址下载安装包时，需要用到isxdl.dll。这个dll需要下载并安装ISTool。

3、.net framework 的下载地址，我找到了除v3.0、v1版本以外的安装包地址，测试时都可用。未来微软网站也许会对这些资源包地址更新，所以不保证一直可用。

4、安装过程中，可通过Inno的函数读取指定目录的.ini文件，并获得文件里的参数值。这个太赞了有木有！一来可以减少在Inno脚本里硬编码，二来可以在安装过程中初始化相关数据。如：Output目录有一个setup.ini文件，里面的内容为：

[Custom]
dotNetVersion =  v4.5

Inno的读取代码：

function GetCustomConfig(key:string):string;
var 
  myValue:string;
begin
  myValue:=ExpandConstant('{ini:{src}Setup.ini,Custom,'+key+'}')
  result := myValue;
end;

//使用
//.....
 GetCustomConfig('dotNetVersion');
//.....
