Hi,

I'm having trouble finding the right news group for this posting so here
goes...

I am attempting to execute some special actions within an installation
project for a standard .Net Windows application. I have a custom
Installer class that needs to access a disk file installed during the
installation in a directory relative to the application directory. The
file name is known but I don't know how to access the target
installation folder during the AfterInstall event of the Installer
class. I'm certain this information is available, I just don't know
where it is. Any suggestions?

On a related note, I'm a little fuzzy on the linkage between an
installer class library and the install project itself. It appears you
do not explicitly instantiate the custom installer in code but reference
the class name under a special action and the special action uses
Reflection to locate and instantiate an instance of the class at
install/uninstall time. Is that correct?

Thanks in advance.

.VB = VB Classic Groups

.dotnet = .Net groups.

It's rare that you would need to post to both

Pass TARGETDIR into your custom action CustomActionData like this:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vsintro7/html/v
xgrfcustomactiondataproperty.asp

You get it from the IDictionary item associated with name if you used /name.

You should just pass it into the Install custom action. There's no practical
difference between Install and AfterInstall, even though the names imply
that one is at the beginning and one at the end.

Visual Studio adds a shim Dll to your setup. Windows Installer calls this in
a standard custom action way (as in the WI SDK) and the shim Dll then finds
your assembly, uses reflection etc as you say.

In a scant hundred years, I'm certain I would have found that. Thanks
for saving me a lot of time.
