I've posted a RDNZL port of the .NET Picture Viewer tutorial on github, https://github.com/rdparker/cl-picture-viewer. This was mostly a learning experience for me but I thought it might come in handy for others. It's neither great Lisp nor highly informed .NET code, but it is a complete application.
Basically I worked through the C# demo, then peered into the code and hand translated it to what is in the repo. But now I have an idea of how to approach creating a .NET interface for a personal research project.
In the course of writing this a couple questions arose.
1. Is there anyway to call BeginInit on a PictureBox without resorting to C++?
Attempting [BeginInit (cast picture-box "ISupportInitialize")] results in a cast error similar to the IConvertible message referred to in http://lists.common-lisp.net/pipermail/rdnzl-devel/2007-April/000390.html.
2. Is it possible to override random method in .NET object via RDNZL?
As an example in the C# code there is an implementation of Dispose, which I was uncertain if I needed to or how to duplicate it:
protected override void Dispose(bool disposing) { if (disposing && (components != null)) { components.Dispose(); } base.Dispose(disposing); }
Edi thank you for writing RDNZL. It has already saved me a lot of time. I'd looked into the managed-unmanaged C++ interop bits of .NET and was not looking forward to writing it all myself.
Thanks,
Ron Parker
Ron, thanks for the info and the link. Good to hear that RDNZL is useful to you. I'm afraid that due to my new job I'm not able to work on RDNZL anymore and in fact there weren't any significant updates in eons because I never used it in earnest. I'm rather surprised that it still works at all after all the .NET updates that came after I initially wrote it. Maybe it'd be a good idea if someone else took over maintenance of RDNZL like Hans did for Hunchentoot and other libs of mine.
Cheers, Edi.
