This should be in the wix-users list, not on wix-devs. wix-devs is for development of the toolset itself.

Subject: [wix-devs] Custom action at cancel uninstallation

Hello, my question is:

How to define a custom action to execute when the cancel button (at
uninstallation) is pressed in WiX Toolset?

I have found that the cancel button should be defined like this:

    <Control Id="Cancel" Type="PushButton" X="304" Y="243" Width="56"
Height="17" Cancel="yes" Text="Cancel">
        <Publish Event="SpawnDialog" Value="CancelButton"/>

And a publish event is defined to the custom action, which could be defined

    <CustomAction Id="CancelButton" Execute="immediate"
ExeCommand='Program.exe"   Return="ignore"/>

An error shows up:  **Unresolved reference to symbol

A Dialog element in WiX cannot have a custom action as child, so where
should be defined that custom action?
