I've been trying to solve this issue for a long time, and nothing seems to work. I have a COM DLL written in vb6. I add a reference to this DLL in .net, with the 'isolated' and 'copy local' properties set to true on the reference. Apparently this is supposed to enable reg-free com. But it doesn't work. If I try on another computer, or ...
We have a proprietary macro language in one of our products, edited through our Windows software. I would like to add intellisense, but I have no idea how to go about this (at least not without completely reinventing the wheel).

Is there any way to Highlight Properties/Functions on your custom classes in intellisense? It's used lots in the Framework and it really helps show main features of a class.

I've read a fair number of questions on how to upgrade a database for developer and such, and I'm leaning towards using migratordotnet or something similar, however it seems the the upgrades need to be run with something like MSBuild or NAnt. These are not things I should expect an end-user to have installed. Ideally the process should...
Hello! Since I'm just learning C# with .NET, (I have more experience with the XNA framework), I might not use it just the right way. My problem is from my view very strange.

If the primary key is named ...

I'm having a problem when trying to pass an array back to a COM caller. Basically, I have a generic List of classes, that I want to return to the COM caller, you can't use generics in COM, so it's got to be strongly typed. I figured just returning a .ToArray() on the List would give me what I need. When I use it in VB6, it works perfe...
