Emacs Copy Current Line -


for reason, copying lines in emacs unintuitive , difficult. if i'm doing wrong here, please let me know. surprising emacs not have default somewhere.

i trying write function copies line. used have:

(global-set-key (kbd "c-x c") "\c-a\c- \c-n\m-w")

this little annoying since copies new line after line. decided change to:

(global-set-key (kbd "c-x c") "\m-m\c- \c-e\m-w")

now, saw: http://www.emacswiki.org/emacs/copyingwholelines , appears copy-line function prints message number of lines copied. trying insert message global-set-key above not working. basically, unable run raw sequence above in function. conveyed each keystroke function , did this:

(defun copy-line ()    (interactive)    (kill-ring-save     (back-to-indentation)     (move-end-of-line 1))     (message "1 line copied")) ;; optional key binding                  (global-set-key "\c-c\c-k" 'copy-line)

this however, throws wrong number of arguments error.

my first question: how can put (message "1 line copied") global-set-key above?

my second question: using standard copy-line found in link above:

(defun copy-line (arg)       "copy lines (as many prefix argument) in kill ring"       (interactive "p")       (kill-ring-save (line-beginning-position)                       (line-beginning-position (+ 1 arg)))       (message "%d line%s copied" arg (if (= 1 arg) "" "s")))

from message, appears can have multiple lines copied. however, when selecting multiple lines , copying, 1 copied. why message structured in way? how can select multiple lines?

here's function, fixed:

(defun copy-line ()   (interactive)   (save-excursion     (back-to-indentation)     (kill-ring-save      (point)      (line-end-position)))      (message "1 line copied"))

the problem back-to-indentation doesn't return point.

as other function, copy multiple lines when called prefix argument, e.g. c-u or m-5.

vb.net - Virtual Keyboard commands -

i wondering difference between virtual these keyboard commands is: keyeventf_extendedkey , keyeventf_keyup is. everywhere have looked gives me description based off integers , not want know each of them does. you've tagged question vb.net, these have nothing @ vb.net. they're constants defined in windows header files, use win32 api functions. as far difference, can't tell looking @ values. individual values not particularly important, that's why named identifiers used. what's important used , documentation functions tells mean. the first one, keyeventf_extendedkey , used keybdinput structure (which used along e.g. sendinput function) pass information synthesized keyboard input. if flag used, means scan code should interpreted extended key. technically, means scan code preceded prefix byte value 224 (&he0 in hexadecimal notation). the second one, keyeventf_keyup , 1 of flags available use structure. means key being released (going up)...
