This page is dodgy. The contents may not be useful for Vim 7. If you think this tip is useful, please edit it to make the problem and its solution more understandable, and remove the {{Dodgy}} tag.

This functionality ought to be covered by syntax folding files. See Tip 108: Folding for more information. However it appears the vb.vim syntax file lacks any folding information. It would best be handled with an extension to or an alternate syntax script, not this awkward method.

If you are using Microsoft Visual Studio .NET for editing Visual Basic .NET files, the Window Form Designer Generated Code is folded by default. If you want to have the same nice feature when editing the same file in Vim, put this code in your vimrc file so you can switch between the folded and unfolded mode:

function! NetFold()
  set foldmethod=syntax
  syn region myFold start="#Region" end="#End Region" fold
  syn sync fromstart
  set foldcolumn=2
endfunction

function! NetUnFold()
  set foldmethod=manual
  set foldcolumn=0
  norm zE
endfunction

So when your are editing a *.vb file, you simply have to call the function like this:

:call NetFold()
or
:call NetUnFold()

Also, if you want that little function to be called automatically when you edit a *.vb file, put these two lines in your _vimrc file:

autocmd BufNewFile,BufRead *.vb setfiletype vb
autocmd BufNewFile,BufRead *.vb call NetFold()
