vb.net - Update Proxy settings from VB application, only works the first time -


i've been trying create simple program change proxy setting, enable/disable proxy. changes setting first time.

i've searched forum , internet, no luck.

i've managed make program work once, when calling toggleproxy() function secound time, first changes registry accordingly, when wininet.dll called refresh setting in internet explorer, old value put registry.

so, when changing proxy , updating ie settings, works fine, when trying change secound time, put backs settings first call.

do need close or clear something? if closing application , starting again, works 1 time again.

is wininet.dll/internetsetoption storing first call somehow?

attaching dll declaration , toggleproxy() function below:

'refresh internet options webbrowsers public declare auto function internetsetoption lib "wininet.dll" (hinternet intptr, dwoption integer, lpbuffer intptr, dwbufferlength integer) boolean public const internet_option_settings_changed = 39 public const internet_option_refresh = 37   'toggle proxy on/off public sub toggleproxy()     'declare temp variable integer     dim setvalue integer     ' if enableproxy regkey 1, set setvalue 0, else set 1.     if proxyregkey = "1"         setvalue = "0"     else         setvalue = "1"     end if       ' change value in enableproxy regkey value set in setvalue         dim autoshell = my.computer.registry.currentuser.opensubkey("software\microsoft\windows\currentversion\internet settings", true)      'set value fo enableproxy according setvalue     autoshell.setvalue("proxyenable", setvalue)     autoshell.close()     messagebox.show("value is:" & setvalue)      're-read proxy regkey.     readproxyregkey()      'refresh internet settings     internetsetoption(intptr.zero, internet_option_settings_changed, intptr.zero, 0)     internetsetoption(intptr.zero, internet_option_refresh, intptr.zero, 0) end sub

appriciate help, seems simple thing, drives me crazy. regards joaqim

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 ...
