vb.net - Remove the windows form controls on exit -


i'm adding form controls on loading form manually:

me.fieldi = new textbox() me.fieldi.location = new system.drawing.point(50, 10) me.fieldi.name = "fieldi" me.fieldi.size = new system.drawing.size(40, 20) me.fieldi.tabindex = 5 me.conversion.controls.add(me.fieldi) [..]

when close form window , reopen it, control still there (with old .text content , because textbox in case).

i remove controls have been created while form loading on form close event, prevent doubling elements on form.

how can achieve this?

edit

form closing code looks following (just showing main form back):

private sub form1(byval sender system.object, byval e system.eventargs) handles me.formclosing     main.show() end sub

the problem here form not being disposed, when open again controls still there last time opened.

try following:

using frm = new subform()   frm.showdialog() end using

the variable frm disposed after using.

also...

you can provide feedback dialog, check whether form successful or not. example:

dim frm new subform() if frm.showdialog = dialogresult.ok   'yay! else   'something failed end if

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers ...
