I need to make the queries from vb.net form with code in visual basic ... I know it depends on B4Xserializator.dll but I can't get it to work ... If anyone is interested we look at the work and the price of the library.
PD. Webservice is working for mobile (Android and iphone)
Best option is to switch to B4J. Another option is to create a non-ui B4J program that is started from the .Net program, as a shell process, and downloads the data.
