I am using Dev7.02 Basics on W2K.
I am to create a package, the package install services using an external install.dll, but I got problem to load the dll. Since I need to call multiple funcitons in one CA, so I can't stream the dll into binary table, I have to do something like calling UseDLL(..). Here is what I am doing:
1) Create a component, which contains the dll file and will be installed to INSTALLDIR/setup folder.
2) In the IScript CA, I load the dll using UseDLL(INSTALLDIR^"setup"^"mydll.dll").
3) Call the functions of the dll.
4) At the end of CA, call UnUseDLL(INSTALLDIR^"setup"^"mydll.dll").
I got error on loading the dll ...
Here is the problem I guess, my script CA points to the correct location (C:\Program files\mycompany\myproduct\setup) on target machine, but when the CA executed, the folder hasn't been created and there is nothing it can load, even I changed the CA to a deferred one (I read a while ago that there is no 'deferred' CA in Dev7? But I still have the option with CustomAction wizard), it still doesn't work.
It seems the CA can't load dlls from the target folders (if I'm wrong, please correct me here - and let me know how I can do it), so how can I make the CA executed after the files (including dll and other files) have been installed?
