In Installshield 5, you could pass lists to external DLLs as described in Knowledge Base article Q102820 (http://support.insta...ticleid=Q102820). Does this still work in some way in Installshield 7? I can't seem to get it to -- when I pass a string list from InstallScripts to a C++ DLL and try to read it, all I get is gibberish. The code I have works fine in Installshield 5.5 Pro. Does anybody know how to get this working? Yeah, I guess I could encode the list as a string and pass that, or write the list to a file and pass that, but I'd like a more sane solution if possible.
