Using .Net classes

[phishguy]

I was browsing the BCX forum and ran across this post.
http://basic-compiler.com/forum/index.p ... topic=35.0

So, it appeared as though it's possible to convert .Net classes to work with a COM interface. There was an example posted for PB and BCX. I converted for use with Freebasic.

Code: Select all

I suppose it is not possible to use Mono this way. Disphelper is a Windows only library. It would be nice to design GUIs etc. with Mono on Linux.
I'll try when I'm on Windows though. Thank you.

Perhaps this will help a bit:
http://www.mono-project.com/Embedding_Mono

So what you do is embed the Mono interpreter and then:
- call Mono routines from FB;
- call FB routines from Mono.

You'll need some C header files to get the embedding done (I don't think FB comes with Mono header files).

Or you can try cilc.

cilc is the Mono CIL-to-C binding generator. It takes a CIL assembly as input and generates a directory of C sources which, when compiled, provide a C interface to the classes contained within that assembly by means of a shared object library.

Generated sources make use of the Mono embedding API. Thus a complete Mono development environment must be available on the development system and a complete Mono runtime environment must be available on target systems.

You'd need a C compiler to produce the library (not a problem on Linux). The routines inside the library should be callable from FreeBASIC.
