What is a TLB file?

What are tlb files?

A TLB file is a small file to help accessing a DLL. This is true for COM or DCOM object. You will use TLB files if for example you make a DLL with Visual Studio 2010 (C# or VB) and want to make if COM visible.
And the best example is when you make a DLL from Visual Studio using any new Framework such as NET 2.0, 3.0, 3.5, 4.0 or 4.5 and wish to make if useable inside any VBA editor (from Excel , Autocad, MicroStation, …)
