vb.net - Error when closing my application in the middle of the loop -


here code loop:

do while potsstatus = true dim foregroundhwnd intptr = getforegroundwindow dim mysearchwinow intptr = findwindow(nothing, searchwindow) if foregroundhwnd = mysearchwinow     if rbq.checked = true         keybd_event(vbkeyq, 0, 0, 0)         keybd_event(vbkeyq, 0, keyeventf_keyup, 0)         thread.sleep(1)     elseif rbw.checked = true         keybd_event(vbkeyw, 0, 0, 0)         keybd_event(vbkeyw, 0, keyeventf_keyup, 0)         thread.sleep(1)     elseif rbe.checked = true         keybd_event(vbkeye, 0, 0, 0)         keybd_event(vbkeye, 0, keyeventf_keyup, 0)         thread.sleep(1)     elseif rbr.checked = true         keybd_event(vbkeyr, 0, 0, 0)         keybd_event(vbkeyr, 0, keyeventf_keyup, 0)         thread.sleep(1)     end if end if

the problem when loop running , exit/close application encounters errors, process remains , loop never ends. thing can manually stop process in task manager. hope can me this.

edit: solved. made loop false in form closing event. thanks.

looking @ code can't see anywhere set potsstatus false (on aside don't need do while potsstatus = true, can do while potsstatus). need have mechanism letting loop know needs stop.

so on form close event set potsstatus false (assuming form wide variable). kind of looks thread candidate although without having better idea of code can't sure.

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 ...
