Question

在玩TestBA Bootstrapper from Bryan时，我首先安装了1.0.0.0。然后我将版本增加到1.0.0.1并记录该过程。以下是升级期间传递-uninstall -quite命令行的部分：

问题：它会显示“卸载”对话框，而不是安静地卸载。如果我单击卸载，它将卸载1.0.0.0然后应用程序将升级到1.0.0.1。

问题：如何让它了解其命令行参数并执行该过程而不显示“卸载”对话框？

我还从Wix 3.7源代码中查询了WixBA项目，但其命令行处理仅处理InstallFolder参数。

我真的很感激任何帮助，因为这个升级方案阻止了我的Bootstrapper项目。

非常感谢。

Answer 1

关键是选取-quiet标志，不显示用户界面，而只是执行所请求的操作。

使用DisplayMode属性通过Bootstrapper基类公开，该属性使用Display枚举值。选项是

public enum Display
{
  Unknown,
  Embedded,
  None,
  Passive,
  Full,
}

然后，您可以通过使用Command.Action枚举的LaunchAction值（再次在Bootstrapper基类中）确定要执行的操作。选项包括：

public enum LaunchAction
{
 Unknown,
 Help,
 Layout,
 Uninstall,
 Install,
 Modify,
 Repair,

}

所以，我使用了一个名为RunningSilent的自定义属性来检测我不应该显示UI的模式，然后使用它，如下所示：

    /// <summary>
    /// True if running in silent display mode (ie: no UI).
    /// </summary>
    public virtual bool RunningSilent
    {
        get
        {
            return (DisplayMode != Display.Full && DisplayMode != Display.Passive);
        }
    }

    protected override void Run()
    {
        if (RunningSilent)
        {
             Log("Running without UI");
             LaunchAction requestedAction = Command.Action;
             //... this is an async call, so handle it accordingly.
             Engine.Plan(requestedAction);
             //... followed by Engine.Apply();

        }
        else
        {
            Log("Showing UI window");
            //.. Run your Managed UI
        }
    }

Answer 2

感谢@John的提示。它在您的提示的帮助下工作。这是我在启动Dialogs（表单视图）之前在Run（）中添加的内容：

if (Command.Display != Display.Full && Command.Action == LaunchAction.Uninstall)
{
   //MessageBox.Show("Let's do Uninstall silentley ");
   MyViewModel.PlanAction(LaunchAction.Uninstall);
}

BTW，就我而言，Command.Display是Display.Embeded，这是预期的行为。

我真的很感激你的提示。再次感谢。
