在后台运行程序 Wix

Question

我编写了一个简单的安装程序，当我使用以下命令时，它会获取属性的值：

msiexec /i file.msi /l*v output.txt IPADDRESS="192.168.2.1"

我在 C# 自定义操作中提取了 IPADDRESS 的值，并创建了两个文件夹 output 和 config。在配置中，我写了 IPADDRESS 的内容，输出用于记录。这是我的 C# 代码：

namespace SetupCA
{
    public class CustomActions
    {
        [CustomAction]
        public static ActionResult WriteFileToDisk(Session session)
        {
            session.Log("Begin WriteFileToDisk");
            string ipAddress = session["IPADDRESS"];
            string path = session["LocalAppDataFolder"]; //With trailing slash
            path = path.Replace(@"\", @"\\").ToString();
            string log_path = path + @"lpa\\output\\";
            string config_path = path + @"lpa\\config\\";
            session.Log("Local App Data Modified Path is: " + path.ToString());
            session.Log("Logging Folder Path is: " + log_path.ToString());
            string temp = @"
{{
 ""logpoint_ip"" : ""{0}"" 
}}";
            string config = string.Format(temp, ipAddress);
            session.Log("Config Generated from property is: " + config);
            System.IO.Directory.CreateDirectory(config_path);
            try
            {
                System.IO.File.Delete(path + "lpa.config");
            }
            catch (Exception e)
            {
                session.Log(e.ToString());
            }
            System.IO.File.WriteAllText(config_path + "lpa.config", config);
            session.Log("Confile file is written");
            System.IO.Directory.CreateDirectory(log_path);
            session.Log("Logging Folder is Created");
            return ActionResult.Success;
        }
    }
}

现在我创建了一个 Visual C++ 应用程序，用于检查程序在启动期间是否已注册。如果没有，它会在注册表中添加 exe 文件并进入无限循环。如果我运行安装的 exe，它会出现在命令窗口中。我想要的是在后台运行exe，用户可以在任务管理器的进程中查看exe。我不想通过显示一个似乎什么都不做的空白终端窗口来打扰用户。这可以在 Wix 中完成还是应该更改我的代码？ 我附上了我的 C++ 代码和 Wix 文件。

我应该如何安装 MSI 文件并在后台运行程序。？请帮忙。 PS：我已经尝试过提供服务。如果我将程序作为服务运行，我不会获得 GetLocalAppDataPath 真实值。

Answer 1

直接的方法是在项目设置中将 C++ 应用程序子系统类型更改为 windows：Linker->System->SubSystem 并将 main 函数替换为 WinMain - 它本身不会创建任何窗口，您可以忽略它的参数和做你目前在main做的事情。

Answer 2

“RegisterMyProgramForStartup”所做的只是写入一个注册表值。这是由 RegistryValue 元素公开的基本 Windows Installer 101 功能。所有这些自定义操作代码都是反模式。
