c# open a new form then close the current form?
...intuitive way in my opinion is to simply close form1 and then create form2 from an outside location (i.e. not from within either of those forms). In the case where form1 was created in Main, form2 can simply be created using Application.Run just like form1 before. Here's an example scenario:

The finally tries to close from the outside of any decorated stream first, so if you had a BufferedWriter wrapping a FileWriter, we try to close the BuffereredWriter first, and if that fails, still try to close the FileWriter itself. (Note that the def...
Why would I use a templating engine? jsp include and jstl vs tiles, freemarker, velocity, sitemesh
...s far simpler than JSP EL or tag libraries
