使用Inno SetUp脚本打包Winform程序

在开发桌面程序时，往往需要用到打包工具将程序打包为exe可执行文件。

之前在项目中用了下 InstallShield Limited Edition for Visual Studio  2015，它的功能很强大，但是需要付费使用，而且有些细粒度的操作比较复杂。

后来，我发现了一款简单方便的打包工具，即我们今天的主角Inno Setup

Inno Setup 支持pascal脚本，这样我们就能通过直接写脚本来实现功能了。

下面我们来看看我们打包过程中常见功能需求：

1. 创建安装exe文件
2. 创建卸载exe文件
3. 创建各种快捷方式，桌面、快速启动栏等
4. 安装、卸载Windows 服务
5. 添加注册表信息
6. 打包.Net framework 环境
7. 安装时不能同时运行两个安装程序
8. 安装/卸载时检测程序(或服务)是否在运行，如果在运行则先关闭程序。

程序的使用方法就不多做介绍了，打开程序新建脚本，会创建出一个基本的框架，然后我们就可以修改脚本添加功能了。

上面的1、2、3 条功能基本的脚本已经帮我们实现了。

关于操作windows服务，我这里收藏了一个极好用的脚本。

有了这个脚本，windows 服务怎么玩都可以了，在[code]  下把这个文件加上就可以使用其中的方法了。

接下来要操作注册表了，在[Registry]下写脚本我们就可以操作注册表了，格式如下：

[Registry]
Root: HKLM; Subkey: "SOFTWARE\ODBC\ODBC.INI\bsjdw101100";ValueType: string; ValueName: "AutoStop"; ValueData: "Yes"
Root: HKLM; Subkey: "SOFTWARE\ODBC\ODBC.INI\bsjdw101100";ValueType: string; ValueName: "Debug"; ValueData: "No"

修改的东西包括，注册表路径、值类型、key和value。

再往下，我们就要写打包.Net framework 进安装包。XP 没有自带.Net framework 环境，有的可能会带 2.0 。win 7 自带 .Net framework 3.5（包含 .NET 2.0 and 3.0） ,Windows 8 默认安装了 .NET Framework 4.5 (包含 4.0)。但是.Net 4.0是不向下兼容.Net 3.5的，所以即使你装了4.0 你的程序可能还是用不了。感兴趣可以参考Net
Framework各个版本区别

下面我们来看看这些脚本怎么写？

首先我们要把.Net 环境加入到打包程序中

[file]
Source: "D:\NetFx20SP2_x86.exe"; DestDir: "{tmp}"; Flags: ignoreversion {#IsExternal}; Check: NeedsFramework
<pre name="code" class="plain">//添加执行操作

[Run]
Filename: {tmp}\NetFx20SP2_x86.exe; Parameters: "/q:a /c:""install /l /q"""; WorkingDir: {tmp}; Flags: skipifdoesntexist; StatusMsg: "Installing .NET Framework if needed"
Filename: {win}\Microsoft.NET\Framework\v2.0.50727\CasPol.exe; Parameters: "-q -machine -remgroup ""{#MyAppName}"""; WorkingDir: {tmp}; Flags: skipifdoesntexist runhidden; StatusMsg: "Setting Program Access Permissions..."
Filename: {win}\Microsoft.NET\Framework\v2.0.50727\CasPol.exe; Parameters: "-q -machine -addgroup 1.2 -url ""file://{app}/*"" FullTrust -name ""{#MyAppName}"""; WorkingDir: {tmp}; Flags: skipifdoesntexist runhidden; StatusMsg: "Setting Program Access Permissions..."

检查目标系统中是否有.Net 环境（以2.0为例），有则安装，无则不装。

//判断是否需要安装.NET Framework 2.0 SP1（或以上）
function NeedsFramework(): Boolean;
begin
  Result := (IsDotNET20Detected = false);
end;

function IsDotNET20Detected(): boolean;
var
    success: boolean;
    sp: cardinal;
begin
    
    success := RegQueryDWordValue(HKLM, 'SOFTWARE\Microsoft\NET Framework Setup\NDP\v2.0.50727', 'SP', sp);
    Result :=  success and (sp >= 1);
end;

接着，我们要建立互斥变量来限制只能运行一个安装程序。

function InitializeSetup():boolean;
var bResult:boolean;

begin
    Result := true;

    //检测是否有另一个安装程序在运行
    bResult :=  CheckForMutexes('MutexBugskySetup');
    if  bResult = true then
    begin
       MsgBox('另一安装程序已经在运行，此安装程序将退出。',mbInformation,MB_OK);
       Result := false;
       Exit;
    end else
    begin
        //没有就创建互斥量
        CreateMutex('MutexBugskySetup');
    end;
end;

接下来我们要检查安装和卸载时是否程序正在运行，为了提示用户保存数据，所以要关闭程序后再安装。

<pre name="code" class="plain">function InitializeSetup():boolean;

var ResultCode:Integer;
var hwnd:HWND;
var CloseNum:integer

begin //先检测进程中程序是否在运行 hwnd := FindWindowByWindowName('{#MyAppName}'); CloseNum := 0; if hwnd <> 0 then begin ResultCode := MsgBox('检测程序正在运行，是否关闭程序继续安装？'#13 #10'选择“是”继续安装；选择“否”，退出安装。',mbInformation,MB_YESNO); //继续安装 if ResultCode = IDYES then begin Result := true; end else begin Result := false; Exit; end; end; while ((hwnd <> 0) and (CloseNum < 5)) do begin //关闭服务程序，尝试5次。 PostMessage(hwnd,18,0,0); Sleep(100); CloseNum := CloseNum + 1; hwnd := FindWindowByWindowName('{#MyAppName}'); end; if IsServiceRunning('{#MyAppServiceName}') then begin StopService('{#MyAppServiceName}'); end end;

end;

卸载的时候，只要在CurUninstallStepChanged（）方法中做同样的事就行了。

好了，就写到这里了，具体的语法和API请参考Inno Setup帮助文档。
