I'm very curios If I develop an algorithm in c++ or vb, would I be able to backtest it using mt4 (I'm referring to the EA backtesting feature, which from my knowledge has a few years of tick database)
My second question would be if someone has coded a VB dll?
Thank you very much

Yes, you should be able to backtest it. You will need to write an EA to be the main "interface" to the DLL, but once you have that, you'll be able to test it much like you would any other EA.
What do you mean? As long as you compile to a DLL (regardless of language) you should be able to use it. I'm pretty sure both VB6 and VB.NET can make DLLs

.NET Dlls (both C# and VB) use a different file format then unmanged C++ dlls. MT4 expects to find the later. To call a VB.NET DLL, you need to add a shim layer in C++ that exports the functions you want to call. Do a goolge search on calling .NET from C++ for details.
Another option that I use successfully is using named pipes. You can import these calls directly into a MQL4 EA from kernel32.dll and past information back and forth to a seperate application. This makes testing and debugging much easier.
