Session.Message在产品安装屏幕上未显示弹出消息

问题描述

我有一个customActions类:

I have a customActions class:

public static ActionResult Register(Session session)
{
     try
     {
         Do SOmething
     }
     catch (Exception ex)
      when (ExceptionManager.catchGenericExcetion(ex))
      {
         var responseMessage =ex.ResponseMessage;
         if (responseMessage.Contains("Maximum apps created"))
         {
             session.Log("maximum limit reached");
             using Record record = new Record(0);
             record[0] = "This is an error!Max apps reached";
             session.Message(InstallMessage.Error, record);
         }
                return ActionResult.Failure;
       }
       return ActionResult.Success;
     }
}

在这里，我的UI没有显示任何与session.Message(InstallMessage.Error，record)相对应的弹出窗口；但是，在MSI日志中，我可以看到打印的消息:达到最大限制

Here my UI doesn't show any popup corresponding to session.Message(InstallMessage.Error, record);However, in the MSI logs, I can see the message printed:maximum limit reached

MSI (s) (30!F4) [21:26:05:047]: Product: MyApp -- This is an error!Max apps reached

任何人都可以帮助我为什么无法在UI上看到此消息吗?我希望在安装过程中将其显示在最终用户的UI上.

Can anyone help that why I am unable to see this message on UI ? I want it to be displayed on the UI for the end user during the installation process.

推荐答案

调试或发布消息 :不确定您真正需要的是-是调试还是做想在安装过程中为最终用户交互式地显示一些东西?

Debugging or Release Message: Not sure what you really need - are you just debugging or do you want to show something interactively during installation for actual end users?

调试 :如果您要调试:将调试器附加到您的自定义项操作，如下所示显示自定义操作的消息框.然后，您可以正确地执行代码-用于快速演示的视频(也许已经为您工作):

Debugging: If you are debugging: Attach the debugger to your custom action after you show a message box from the custom action like below. Then you can step through the code properly - video for quick demo (perhaps this is already working for you):

using System.Windows.Forms;

<..>

[CustomAction]
public static ActionResult TestCustomAction(Session session)
{
   MessageBox.Show("Hello from TestCustomAction");
   return ActionResult.Success;
}

Session.Message :我并没有真正使用这个概念(我喜欢将信息放入日志中，而不是显示给最终用户)，但是我发现了这一点工作(从这里清除- 准备好的搜索" ):

[CustomAction]
public static ActionResult TestCustomAction(Session session)
{
    Record record = new Record(0);
    record[0] = "This is an error! Max apps reached";

    session.Message(InstallMessage.User | (InstallMessage)MessageButtons.OK | (InstallMessage)MessageIcon.Information, record);

    return ActionResult.Success;
}
