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!

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 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?

"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.
