在用户提示“手动关闭"之前，WiX会在卸载时调用应用程序 [英] WiX call app on uninstall before User prompt "close manually"

问题描述

我有一个安装程序，可以安装应用程序，并在安装完成后立即启动该程序.这对我来说正常工作.

I got an installer which installs an application and starts this one right after the installation was finished. This works properly for me.

但是现在我想在卸载应用程序时停止该应用程序，我不希望提示用户手动关闭应用程序.这将是全自动的.

But now I want to stop that application while uninstalling the application, i don't want the user to be prompted to close applications manually. This shall work full automatic.

我需要使用自定义操作来执行此操作，WM_CLOSE消息在我的方法中不起作用(确实，我尝试了几次).

I ned to do this using a custom action, the WM_CLOSE message will not work in my approach (really, i tried it a couple of times).

我认为这不是那么困难，但是我没有使它起作用.我到目前为止所做的:

I thought that this can't be that difficult, but I don't get it to work. What I did so far:

我定义了一个CustomAction:

I defined a CustomAction:

<CustomAction Id="CloseTrayApp" ExeCommand="-exit" FileKey="TrayApp" Execute="immediate" Return="asyncNoWait" />

并称其为:

<InstallExecuteSequence>
...
    <Custom Action="CloseTrayApp" Before="InstallValidate" />
...
</InstallExecuteSequence>

但这不起作用.我猜我在错误地执行了自定义操作，但是我找不到正确的时间来执行此操作.

But this does not work. I guess that I'm sheduling my custom action wrong, but I can't figure out the correct time to do it.

是否有建议解决自定义动作的时间/地点?我不确定

Are there any suggestions regarding the time/place to shedule the custom action in? I'm quite unsure if

Before="InstallValidate"

是正确的选择.

推荐答案

每个

Per the FilesInUse Dialog help topic, before InstallValidate is the correct place to schedule the custom action. But I'm confused as to why the WM_CLOSE won't work for you. I saw you asked another question and accepted it as the answer. Perhaps your TrayApp could have a "hidden" form that the user never sees but is running to receive the WM_CLOSE message. This is a trick I've done many times over the years.

否则，如果您确实要调用EXE，建议不要使用EXE自定义操作.而是使用安静执行自定义操作.出于某些原因，请参见 EXE自定义操作的集成障碍.

Otherwise, if you really want to call your EXE, I suggest never using an EXE custom action. Instead use the Quiet Execution Custom Action. For some reasons on why to do this see Integration Hurdles for EXE Custom Actions.
