vba - ms access form closing ask save yesnocancel -

-

i have put vba in unload form event in ms access 2010 

private sub form_unload(cancel integer)  dim strmsg string    dim iresponse integer     ' specify message display.    strmsg = "do wish save changes?" & chr(10)    strmsg = strmsg & "click yes save or no discard changes."     ' display message box.    iresponse = msgbox(strmsg, vbquestion + vbyesnocancel, "save record?")     ' check user's response.    if iresponse = vbyes        ' undo change.       docmd.runcommand accmdsave    end if     if iresponse = vbno         ' undo change.       docmd.runcommand accmdundo       end if       if iresponse = vbcancel        ' undo change    cancel = true      end if    end sub

if data changed above code working fine, yes save & close, no undo & close , cancel cancel event , remain on form when data unchanged yes button working fine, no button not close form

where m mistaking ?

your question vague because state "no button not close form."

you can do:

docmd.close

see here:

private sub cmdcloseform_click()  on error goto err_cmdcloseform_click    docmd.runcommand accmdundo  'or me.undo - test works best situation  docmd.close   exit_cmdcloseform_click:   exit sub   err_cmdcloseform_click:   msgbox err.description   resume exit_cmdcloseform_click   end sub

on me.undo allen browne:

me.undo cancels edits in specific form, no longer dirty. once form no longer dirty, no further undo possible, because has reached desired state. however, me. represents form in focus, form must have focus perform me.undo command.

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...
