I have a C++ app in VS2005 and import a VB DLL. IntelliSense shows me all the symbols in the DLL as expected but it also shows all (or nearly all) of them again with an underscore prefix (no @s in them though). Why is this? What are the differences between the underscored items and the normal items?
Assuming you’re talking VB6, the leading underscore version _Klass is the Vb-generated default interface for the class Klass. This site has a nice explanation: http://www.15seconds.com/issue/040721.htm
