When you work with COM DLLs, you will typically ask Visual Studio to add a reference to that DLL. Behind the hood, Visual Studio will automatically generate a wrapper around that DLL to let you access it easily.
And it works fine !
However, in some cases, you may want to generate yourself this wrapper, specially if you need to control the creation's options.
You will see here how you can use the tlbimp.exe tool to generate the DLL. [Plus]
