Call non-registered .NET dll from Excel VBA

Question

I need to write a .NET dll that can be called directly from an Excel\'s VBA Module such that the dll and .xls are simply deployed in the same directory without any COM regis

Have you seen this MSDN article? Basically you register functions from a DLL, not a DLL itself. I don't know if it is put very clear in the article, but the syntax is:

[Public | Private] Declare Function name Lib "libname" [Alias "aliasname"] [([arglist])] [As type]

where "libname" can contain full path e.g. "C:\tmp\algo.dll" or only a name e.g. "algo.dll". In the second case the local path will be searched for a matching binary.
