Import the functions from your executable and use it as if it were a local function. Have a look at LoadLibrary(), GetProcAddress(). You will get started then.

Almost all your questions are urgent. But unfortunately, you will get your query resolved only if you follow the guidelines[^] while asking a query. :)

The simplest way to use such DLLs is via load time linking: Add the corrensponding import library as linker input: select Project->Properties menu item, then Configuration Properties->Linker node and add, for instance, comdlg32.lib to Additional Dependecies line. Usually you have also to include the library header file in you project (it is not the case of comdlg32.dll: windows.h is enough) and make sure that loader is able to find the DLL at runtime (again nothing to do for comdlg32.dll, since it is already in the loader search path). :)

I think it was the four seasons, (orginal title: "le quattro stagioni"). I don't remeber if I have it, since Vivaldi is not my favourite composer (I like very much Verdi and Bach). I will look for at home. :)

Nope. I like Giuseppe Verdi[^], I think he was the best Italian composer (I like so much the Aida opera), however I'm far of being a musician, hence my opinion maybe irrelevant (simply I like very much his brilliant usage of winds and percussions).

I hope, once at home, to remember about (don't blame me if I forget, I'm very absent-minded) :)
