when accessing form or query string value code-behind in asp.net, pros , cons of using, say: // short way string p = request["param"]; instead of: // long way string p = request.querystring["param"]; // if it's in query string or string p = request.form["param"]; // posted form values i've thought many times, , come with: short way: shorter (more readable, easier newbies remember, etc) long way: no problems if there form value , query string value same name (though that's not issue) someone reading code later knows whether in urls or form elements find source of data (probably important point) . so other advantages/disadvantages there each approach? the long way better because: it makes easier (when reading code later) find where value coming from (improving readability) it's marginally faster (though isn't significant, , applies first access) in asp.net (as equivalent concept in p

we using web-ehcache's net.sf.ehcache.constructs.web.filter.simplepagecachingfilter, configured xml, cache page json message, message can changed administrator. how invalidate cache when administrator changes changes json message? i figured out how make it: cachemanager.getinstance().getehcache("cachename").removeall(); it gets singletone cachemanager, gets ehcache depending on name of cache, removes elements. in next request cached page, filter looks ehcache, finds, without elementx , updates elements!

i'm experimenting drawable backgrounds , have had no problems far. i'm trying change gradient background color @ runtime. unfortunately, there's no api change @ runtime, seems. not trying mutate() drawable, explained here: drawable mutations the sample xml looks this. works, expected. <shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle"> <gradient android:startcolor="#330000ff" android:endcolor="#110000ff" android:angle="90"/> </shape> sadly, want list various colors, , they'd have programatically altered @ runtime. is there way create gradient background @ runtime? perhaps not using xml altogether? yes! found way! had forget xml, here's how did it: on getview() overloaded function (listadapter) had to: int h = v.getheight(); shapedrawable mdrawable = new shapedrawable(new rectshape());

we have form in ms-access can viewed either in form or datasheet mode. the form arranged in such way labels aren't required of textboxes. in datasheet mode however, kind of column heading required , default behaviour takes control name (as in txtretailprice ) ugly. is there way set datasheet column header text without putting labels on underlying form . i've said, form nicely laid out , adding labels in there confusing. i'm hoping there solution preferably doesn't involve adding redundant labels form. i know old post , question answered, answer might helpful you. you didn't mention version of access, in access 2010 there's textbox property called datasheet caption. when insert space value property, column header in datasheet show blank. hope helps.

i want write logging http module stores list of log events single request in thread local storage while request executes. on end_request want write events persistent storage. question is, 1 request match 1 thread? i.e. can assume anywhere in code can add items ienumerable , @ end of request. no. asp.net can potentially switch threads while processing request. known thread-agility. there points can/will this. can't remember off top of head - searching reference now... but short answer no : can't rely on same thread-local storage being accessible entire duration of request.

i'm looking easy way convert variables , function names lower_case uppercase in java code. there's lot of code, refactoring names 1 one isn't idea. it means function public void create_table(string table_name) { int useless_var = 0; useless_function("string_param"); // comment should not altered, even_if_i_use_some_underscores } should become public void createtable(string tablename) { int uselessvar = 0; uselessfunction("string_param"); // "string_param" must not become "stringparam" // comments should left untouched, even_if_i_use_some_underscores } and on. i know can python script, take time , can make mistake converting not identifier. that's why want know if there's tool or this. most java ides can cascade changes make 1 variable ever used. believe tools pmd can find these cases might not in fixing them. if working application, might want make corrections perform maint

here concern, my problem not powershell, way have use implement persistence. cases there more 4 commands logic or apply persistence. for example: when configuring dns zone, normal new/get/set/remove-dnszone and suspend/unsuspend-dnszone. how teammates handling make method on repository handle commands. it seems me behavior should instead on object , suspend/unsuspend-dnszone should called when create or update executed on repo. what think? edit requested, i'll put code demonstrate talking about. this fake example similar implementation of our powershell wrapper. method on repository teammates do: public void suspend(dnszone zone) { _powershell.execute("suspend-zone", new dictionary<string, object>{{"name", zone.name}}); } so somewhere in logic, suspend zone have call var myzone = new dnszone{ name= "xyz"}; _zones.suspend(myzone); instead, prone dnszone should have property or method. logic not in repo in object i

i need redistribute gdiplus.dll v.1.1 app , sure particular version used. e.g. windows xp has system version of gdiplus.dll can not upgraded (v.1.0). if put gdiplus.dll application folder, system 1 still used. why? how resolve this? msdn says : if redistributing gdi+ downlevel platform or platform not ship version of gdi+ natively, install gdiplus.dll in application directory. puts in address space, should use linker's /base option rebase gdiplus.dll prevent address space conflict. but have no clue how rebase gdiplus.dll , what, can explain this? [edit] seems microsoft decided not ship gdi+ 1.1 windows xp, vista , on. nice move. thank all you don't need rebase it. if don't dll rebased automatically whenever loaded. have mild impact on start-up speed guess won't detectable. however, seems cannot redistibute gdi+ 1.1 xp: how install gdi+ version 1.1 on windows xp?

"potential leak of object allocated on line n , stored ' variable '." normally helpful analyzer warning, there few situations annoying false positives suppress keep analyzer results clean. in analyzer's defense, it's noticing memory leak not release in path of execution (to blind). i'll elaborate on situation. happens in various flavors, general pattern follows: an object allocated , delegate set. something done object. (a task started, view displayed, etc). execution of current method ends. (enter clang warning). object decides task complete, sends delegate message. delegate releases object. this not @ esoteric design pattern, i'm hoping suppression possible. know can avoided storing offending object in ivar later released, prefer not add ivar pollution. clang has few new source annotations . in specific, may interested in ns_consumed attribute.

how can test ios application on ipod touch without registering apple developer program or jailbreaking ipod? neither viable option @ moment. i'd test on device instead of onscreen emulator, see how performs on actual ipod. seven years after inception of app store (july 10, 2008), apple has introduced new feature in xcode 7 allows deploy , run number of apps on of devices, logging in apple id. you no longer need paid program membership deploy apps on own device (and no longer have jailbreak device if you're not comfortable doing so). well, not majority of use cases anyway. obvious reasons, capabilities , entitlements require program membership such game center , in-app purchases not available apps deployed using method. apple's developer documentation : launch app on devices using free provisioning (ios, watchos) if don’t join apple developer program, can still build , run app on devices using free provisioning . however, capabilities available

in haskell, i'd generate list of random integers of undetermined length. (however, less 1 million.) i'm not need elements of list immediately, i'd generate lazily. however, once generated, i'll need access elements in list random access. so, assume best technique copy infinite list array. however, don't know if arrays can "interchanged" lists -- instance, once want generate more items of list, want start left off expand array. anyways, perhaps should settle log(n) tree structure instead of array? think? does haskell have tree structure sequential elements can accessed using list-like api? if have prng, values generated seeds close should independent, can choose initial seed, each cell i in array prng(seed+i) . this using hash function :p if way, don't need array, can have function getrandomvalue seed = prng (seed+i) . whether or not better array of lazy values depend on complexity of prng, either way you'll o(1) access.
