You're welcome.<g>
Every custom action that modifies the machine is tied, directly or
indirectly, to a component. The compiler extension and schema make the
authoring be a child of Component or a grandchild of Component such as
File, CreateFolder, etc. Then the custom table in the .msi includes that
component so the custom action can query for it and then use
WcaGetComponentTodo (etc) to see if the component is active and if so,
what's happening to it:
enum WCA_TODO
{
WCA_TODO_UNKNOWN,
WCA_TODO_INSTALL,
WCA_TODO_UNINSTALL,
WCA_TODO_REINSTALL,
};
I'm biased, but I'd suggest looking at ca\wixca\dll\netshortcuts.cpp;
it's a lot simpler than IIS but has the same kinds of things in it.
