It's my understanding that FreeBasic is like VB in that it's compiled to "fake" code and is then executed by an interpreter. So, using a C library to do this will be faster.

I tried to make a lump.dll for Fyre for VB, but I don't > think he got it working - VB seems to require special activex dlls or > something. DLLs work fine. You have to use Declare Function. Something like this: In C: int function_name(int &var1, int var2); In VB: Declare Function function_name Lib "dllname.dll" (ByRef var1 As Integer, ByVal var2 As Integer) As Integer If you actually want to associate the DLL with the project, it has to be an ActiveX DLL. It's easier to do it using Declare Function. Or, option #2 is to write a .ocx (ActiveX Control) in VB that executes stuff in the DLL and then have VB users use the VB OCX.
