使用wix卸载之前，请关闭systemtray应用程序 [英] Close a systemtray app before uninstalling using wix
问题描述
我知道过去曾问过类似的问题，但到目前为止我仍然没有找到解决问题的方法。
I know similar questions have been asked in the past but I still haven't managed to find a solution to my problem as of yet.
我有一个正在运行的系统任务栏应用程序，我想在卸载开始之前将其关闭，并显示 FileInUse对话框，但我正在执行的操作似乎无效。为了关闭我的系统任务栏应用程序，我需要在安装文件的文件夹中创建一个文件。然后，应用程序将删除文件并自行关闭。
I've got a system tray app that's running and I want to close it before uninstall begins and displays the "FileInUse" dialog but whatever I'm doing doesn't appear to work. In order to close my system tray app, I need to create a file in the folder where it is installed. The app then deletes the file and closes itself.
根据我的尝试，我遇到以下问题：
I'm getting the following issues depending on what I've tried:
1）显示 FileInUse对话框。不好
1) The "FileInUse" dialog gets displayed. No good
2）无法调用我的自定义操作，该操作创建了一个文件来通知我的系统任务栏应用程序应关闭。
2) Failing to call my custom action which create a file to notify my system tray app that it should close.
Error 1 ICE77: CloseAgentMonitor is a in-script custom action. It must be
sequenced in between the InstallInitialize action and the InstallFinalize action in
the InstallExecuteSequence table
3）如果将我的应用程序文件夹设置为立即 CustomAction >代替立即，但是如果将其设置为 Deferred ，则会出现2）中提到的错误
3) Fails to pass my application folder as a CustomData parameter to the CustomAction if I set it to Immediate instead of Immediate but if I set any it to Deferred, I get the error mentioned in 2)
4）我尝试了不同的场景，不同于在 RemoveFiles ， InstallValidate ， InstallFinalize 。
4) I've tried different scenarios from calling the custom action before RemoveFiles, InstallValidate, InstallFinalize.
由于我不确定正确的顺序是什么，有人可以告诉我如何以及何时调用我的CustomAction，以便触发它， Remove按钮已关闭，或者在文件开始被删除之前。
As I'm not sure what are the correct sequences, can someone tell me how and when to call my CustomAction so that it is triggered the "Remove" button is closed or before the files starts to get removed.
我想在卸载文件时并且在显示 FileInUse 对话框之前执行此操作。
I want to do this when uninstalling the files and before the FileInUse dialog is displayed.
请注意，无论是静默卸载还是可视卸载，我都非常重要。
Note that it's really important that I can handle this in both silent or visual uninstall.
谢谢。
更新：
我可能应该发布我的wix代码：
I probably should have posted my wix code:
<!-- Set variables required by the CloseAgentMonitor CustomAction -->
<CustomAction Id="CloseAgentMonitorSetProp"
Return="check"
Property="CloseAgentMonitor"
Execute="immediate"
Value="APPLICATIONFOLDER=[APPLICATIONFOLDER]" />
<!-- Define CustomAction to close the Agent on uninstall -->
<CustomAction Id="CloseAgentMonitor"
Return="check"
Execute="immediate"
BinaryKey="CustomActions.CA"
DllEntry="CloseAgentMonitor" />
<InstallExecuteSequence>
<!- Make sure to set the props before the CloseAgentMonitor custom action -->
<Custom Action="CloseAgentMonitorSetProp" Before="CloseAgentMonitor">
<![CDATA[(Installed AND NOT UPGRADINGPRODUCTCODE)]]>
</Custom>
<Custom Action="CloseAgentMonitor" Before="InstallValidate">
<![CDATA[(Installed AND NOT UPGRADINGPRODUCTCODE)]]>
</Custom>
...
更改 CustomAction 立即进行设置，并将其设置为在 InstallValidate 整理出2中提到的问题之前被调用，但是它带回了第3点中提到的错误，在那里我的<没有设置code> CustomActionData ，甚至认为应该这样，因为它是在 CustomAction 之前调用的。
Changing the CustomAction to immediate and set it to be called before InstallValidate sorts out the problem mentioned in 2, but it brings back the error mentioned in point 3, where it appears that my CustomActionData is not being set, even thought it should be since it is called before the CustomAction.
您可以从我的日志中清楚地看到它是：
You can clearly see from my logs that it is:
MSI (s) (30:08) [16:22:47:148]: Doing action: CloseAgentMonitorSetProp
MSI (s) (30:08) [16:22:47:148]: Note: 1: 2205 2: 3: ActionText

但是您可以看到我的 CustomAction 被调用，尝试访问 APPLICATIONFOLDER 时会触发错误。
But as you can see when my CustomAction is called, it triggers an error when trying to access the APPLICATIONFOLDER.

推荐答案
我知道了！
我简直不敢这么简单！我需要做的所有工作都花了几个小时，将 session.CustomActionData [ APPLICATIONFOLDER] 更改为 session [ APPLICATIONFOLDER] 。
I can't believe it was that simple! Spend hours looking into it when all I had to do, was change the session.CustomActionData["APPLICATIONFOLDER"] to session["APPLICATIONFOLDER"].
我最初开始使用会话变量，但是遇到了各种问题，所以我最终使用了 CustomActionData ，但是我只是
I originally started using the session variables but hit various problems so I ended up using CustomActionData but I've just checked and all my custom action were deferred up to now.
因此，如果我正确获取Wix，则应使用 CustomActionData 延后的 CustomAction ，则应在直接 CustomAction 中使用会话的变量。
So if I get Wix correctly, you should use CustomActionData in deferred CustomAction and you should use the session's variables in immediate CustomAction.
因此您自定义操作中的代码应为：
So code in your custom action should be:
string applicationFolder = session["APPLICATIONFOLDER"];
而不是
string applicationFolder = session.CustomActionData["APPLICATIONFOLDER"];
希望这对其他人有帮助！
