从CA到Wix的Wix自定义操作设置值 [英] Wix Custom action set value from CA to wix

问题描述

在延迟（使用impoersonate = no）将值发送到WIX到CA的过程中，我正在使用set属性和值

In deferred ( with impoersonate = no) to send the Value to the WIX to CA, i am using set property and value

并使用session.CustomActionData [ key];

and collecting the data in CA using session.CustomActionData["key"];

有没有办法将数据从CA发送回WIX

Is there any way to send back the data to the WIX from CA

<Property Id="RESTART" Secure="yes" Value="false" />

在我刚使用时，

session["RESTART"] = "true" 

。如何在延迟的CA中实现此目的

... how to achieve this in deferred CA

推荐答案

您无法通过延迟的自定义操作修改会话；那时，MSI正在执行其脚本，因此没有会​​话可言。因此您无法设置媒体资源。您需要其他某种机制来传达状态。 WiX的本机库包含功能 WcaDeferredActionRequiresReboot 来标记需要重新启动，而功能 WcaDidDeferredActionRequireReReboot 用于在 InstallFinalize 来检测重新启动状态。

You cannot modify the session from a deferred custom action; at that point, MSI is executing its script and there's no session to speak of. So you can't set a property. You need some other mechanism to communicate status. WiX's native library includes the functions WcaDeferredActionRequiresReboot to flag that a reboot is required and WcaDidDeferredActionRequireReboot for an immediate custom action scheduled after InstallFinalize to detect the reboot status.
