Calling Dll function from Custom Action

Hi All,

I am using MSI for installing my application.
I have created a custom action dll and added custom actions from it.
I want to call some functions of dll present in binary table from custom
actions.
Is it possible to do it? How can I achieve this?

If any one have idea about it, then please tell me.
Waiting for your reply.

Thanks & Regards,
Pariksheet.

There are APIs to extract data from binary tables, from which you can create
the Dll. I can only find this right now:

http://makemsi-manual.dennisbareis.c...stall_time.htm

which is VBScript, but there are equivalent Win32 calls.

Alternatively you could just install those Dlls to [TempFolder]. When your
custom action runs (if it's deferred and after files are installed) you
could do LoadLibrary of the Dlls in the temp folder and call functions. If
they have null ComponentIDs in theitr Components you can remove them later
without fear of restoring them from a repair.
