Gook to know you're developing in gambas.
The thing to do to get your application in the Vector stream is to post an announcement describing what the application does and where to get it.
If you are developing in gambas, you may want to make sure you have created a source package that other users can build the your binary from.
To do this, follow this instructions. In the gambas IDE, with your project open
Project -> Make -> Installation Package.
Follow the wizard, and fill in any necesary information.
When you get to the step labeled "Target Distribution", select "Autotools"
When you finish, you will end up with a package that can be compiled using the standard autotools of the GNU system.
Upload that source package somewhere and post the announcement. I'll try to build it and upload it. But you gotta give us an introduction to the application
This is how I've done it in the past, but my apps are vl-exclusive toolshttp://forum.vectorlinux.com/index.php?topic=4875.0
And I started this back in the days... as a cli app then made a gui for it using gambas2http://forum.vectorlinux.com/index.php?topic=2661.0
