excel - Formula to use current value of a cell, which won't update in the future -

-

is there function use current value of cell, won't update in future if change value of target cell?

for example: a1 = 5

a3 = a1 (which equals 5)

now, when change value of a1 6 a4 = a1 (should equals 6, a3 should remain 5)

is possible in excel?

say start a1 , a4 both empty. following event macro allow enter value in a1 , have appear in a4. each time value in a1 changed, new value copied first empty cell below a4.

enter following event macro in worksheet code area:

private sub worksheet_change(byval target range)     dim a1 range, a4 range, n long     set a1 = range("a1")     set a4 = range("a4")     if intersect(a1, target) nothing exit sub     application.enableevents = false         if a4.value = ""             a4.value = a1.value         else             n = cells(rows.count, "a").end(xlup).row + 1             cells(n, "a").value = a1.value         end if     application.enableevents = true end sub

because worksheet code, easy install , automatic use:

  1. right-click tab name near bottom of excel window
  2. select view code - brings vbe window
  3. paste stuff in , close vbe window

if have concerns, first try on trial worksheet.

if save workbook, macro saved it. if using version of excel later 2003, must save file .xlsm rather .xlsx

to remove macro:

  1. bring vbe windows above
  2. clear code out
  3. close vbe window

macros must enabled work!

C# random value from dictionary and tuple -

-
i have following code, , need random item contains string "region_1" dictionary. public static dictionary<int, tuple<string, int, currencytype>> itemarray = new dictionary<int, tuple<string, int, currencytype>>() { { 0xb3e, new tuple<string, int, currencytype>("region_1", 1500, currencytype.fame) } }; public static int generateitemid(string shopid) { var generateditem = itemarray.elementat(new random().next(0, itemarray.count)).key; } how select this? it's not possible efficiently... first create static random @ class level... prevent non-random behaviour if run query on short period of time... (it's seeded discrete clock) static random rnd = new random(); then: var item = itemarray.values .where(t => t.item1 == shopid) .orderby(_ => rnd.next()) .firstordefault()

cgi - How do I interpret URLs without extension as files rather than missing directories in nginx? -

-
so i'm trying install zoneminder , have run under nginx, has few compiled files need run using fast-cgi. these files lack extension. if file has extension, there no issue , nginx interprets file , return 404 if can't find it. if has no extension, assume it's directory , return 404 when can't find sort of index page. here have now: # security camera domain. server { listen 888; server_name mydomain.com; root /srv/http/zm; # enable php support. include php.conf; location / { index index.html index.htm index.php; } # enable cgi support. location ~ ^/cgi-bin/(.+)$ { alias /srv/cgi-bin/zm/; fastcgi_pass unix:/run/fcgiwrap.sock; fastcgi_param script_filename $document_root/$1; include fastcgi.conf; } } the idea is, under cgi-bin directory goes through fastcgi pipe. any idea on howi can fix this? upon closer inspection, realized zoneminder has 2 cgi sc...
