Hi,

Does that mean that the resulting file can be used just as if it were an ordinary VCX file and can issue SET CLASSLIB TO?
<<

No. You get a COM dll which can be called from any app (VFP,VB,ASP,Word whatever). You *can* us this from VFP using 'CREATEOBJECT('dllname.classname') but if you don't need to expose your classes functionality outside of VFP then you don't need to build a DLL.

>>And will it be 'encrypted' (as if in an EXE)?<<
Yes

>>
As developers we don't distribute our VCX files right?

Normally no - if you're building an .EXE from your project then class libraries added to the project will be compiled into the .EXE.

Hope this makes sense, Regards,
