vb.net - Sending PictureBox Contents to MsPaint -


how go sending contents of picturebox edited in paint? i've thought of saving temporarily sending temp address loaded, i'd think cause minor saving issues.

unfortunately i'm providing answer in c# @ time. luckily, syntax , not content have change.

assuming picturebox control, take contents (as bitmap) , put on clipboard. can paste mspaint you'd sendmessage or sendkeys if make foreground, etc.

bitmap bmp = new bitmap(picturebox1.image); clipboard.setdata(system.windows.forms.dataformats.bitmap, bmp);

a poor example, optional opening of mspaint , waiting appear, using sendkeys paste.

    [dllimport("user32.dll", setlasterror = true)]     public static extern intptr findwindowex(intptr parenthandle, intptr childafter, string classname, string windowtitle);      [dllimport("user32.dll")]     private static extern intptr getforegroundwindow();      [dllimport("user32.dll")]     [return: marshalas(unmanagedtype.bool)]     static extern bool setforegroundwindow(intptr hwnd);       private static void testsendpicturetomspaint()     {         bitmap bmp = new bitmap(picturebox1.image);         clipboard.setdata(system.windows.forms.dataformats.bitmap, bmp);          //optional#1 - open mspaint         //var proc = process.start("mspaint");          intptr mspaint = intptr.zero;         //while (mspaint == intptr.zero) //optional#1 - if opening mspaint yourself, wait appear         mspaint = findwindowex(intptr.zero, new intptr(0), "mspaintapp", null);          setforegroundwindow(mspaint); //optional#2 - if not opening mspaint          intptr currforeground = intptr.zero;         while (currforeground != mspaint)         {             thread.sleep(250); //sleep before exit loop , send             currforeground = getforegroundwindow();         }         sendkeys.sendwait("^v");     }

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 ...
