I'm new to Mapinfo and Mapbasic as well. I need to build a tool like in ArcMap (pythonaddins). The goal is to have a gui application which has three dropdown lists. First is a list of layers in workspace. Second one is a set of fields inside the selected table This Third is a list of values that have to be written in a specific field (according to selected features).
I already discovered that Mapbasic can make dialog windows but things that I tested were working for one time while I needed a tool to be like an instrument which will stay always in Mapinfo window. Any suggestions?
