i have code in vb6 creates moderately-large tree structure (a few thousand nodes). performance adequate except when destroying last reference tree. can take second or more. i've tried killing internal references within each node before deleting node itself, doesn't seem help. there trick speed whatever vb6 doing reference counters? there seems significant n^2 aspect performance. incidentally, know vb6 obsolescent, have complaining code wrote quite time ago still in use. btw, tree not binary tree, instead allows each node have arbitrary number of children, held in collection , accessed name (so 1 node might thetree!this!that!theotherthing!whatever, aka thetree("this")("that")("theotherthing")("whatever")). vb6 collection objects notorious being slow release contents, esp when there's lot of contained references. you might try replacement collection, this . there's number of other replacement collections vb6

i have submit button, created - when clicked want groupbox appear below submit button is....any suggestions? i've tried request given of click doesn't me. thought logic similar this: <form> <input type="checkbox" name="group" value="yes" />yes <input type="checkbox" name="group" value="no" /> no <input type="submit" value="submit" /> </form> <% string[] select = request.getparametervalues("group"); /* add code creation here */ %> any suggestions or examples can think of? thanks greatly, u. first replace checkboxes radio buttons. right it's possible check both yes , no . makes no sense. <form> <input type="radio" name="group" value="yes" /> yes <input type="radio" name="group" value="no" /> no <input type="submit"

is there way use pre-compiled headers in vc++ without requiring stdafx.h? regarding first answer question above, i tried implement solution using visual studio 2010, , failed: fatal error c1010: unexpected end of file while looking precompiled header. did forget add '#include "stdafx.h"' source? any ideas? the objective not use #include "stdafx.h" anywhere, instead decide on whether or not use during compile time. if /yc or yu not used, #pragma hdrstop has no effect if yu used, #pragma hdrstop replaced #include "stdafx.h", or @ least thats claimed behavior. the error message indicates had option /yu "stdafx.h" when compiling. answer suggested leave "stdafx.h" part of /yu option blank.

when compare 2 versions of ms word doc/excel book in team foundation server source explorer, result boring "binary filles differ" dialog. it not have way though. relevant apps (word/excel) have excellent built-in diff interface. can witness when work versioning-enabled sharepoint file library , compare previous version. also, tortoisesvn brings when diffs. question - can enable in tfs? you can configure comparison (diff) , merge tools per file type (extension). available via tools -> options -> source control -> visual studio team foundation server -> configure user tools" button or via command-line tf diff /configure in order set comparison tool, you'll specify extension (use .* if want used files not otherwise specified), operation you're setting (compare or merge), command invoke , arguments command. arguments, variables available use following: %1 = original file (in diff, pre-changes file, in merge, "server" or

why memory in silverlight? data: i having many check boxes , others on user interface sometimes. matter of course, removing check boxes , other controls visuals, memory usage of silverlight increases; never decreases. how ensure memory released? is problem garbage collection? how find root of remaining objects no reference not yet collected? i can provide more data if needed. the memory management engine silverlight uses similar 1 clr uses wpf , other traditional .net applications. based on garbage collection , if maintain references objects, accidentally, prevents them being garbage collected, memory consumption continue increase. if have problem in silverlight application can around leaks or can try use tools leaks , find of memory being allocated. quickest way memory profiler. unfortunately there not lot of memory profilers work silverlight ants profiler, has free trial version, supposedly does: ants memory profiler 7.0

how sum of fibonacci sequence using code: fibs= 0 : 1 : zipwith (+) fibs (tail fibs) edit: take 5 fibs gives list of [0,1,1,2,3], value of 5th element 3, extract have type : 'last(take(5 fibs))' , 3. , on if use interpreter seek 5th element list of [ 0, 1, 2, 3] last element same value of 5th element, how last element of list? can 'make' using last , have ideas, you? i'm not entirely clear you're asking, if have non-empty non-infinite (i.e., not fibs but, example, take n fibs n ) list, can indeed obtain last element applying last it. alternatively, if want n-th element of list (starting @ 0 , assuming list has @ least n+1 elements), can listname !! n extract it.

suppose have following table: state companytypes year sales az a, c 2008 ca b, c, d 2009 tx c 2007 wa a, d 2008 i need fill out sales column, based on sum of sales across company types particular state in particular year. the source table data looks this: year state companytype totalsales 2008 az 100 2008 az c 500 2009 ca b 9000 2009 ca c 15664 2009 ca d 12351 2008 tx c 5 2009 wa 789 i familiar sumif , not know how fill in sales column of first table because of comma separated values in companytypes column. does know?? ray, notice sales table has following property: in each row, state , year combination unique in sense "az" , "2008"

i have following lines in vclinkertool section of project: outputfile="$(outdir)\bin\engine.dll" importlibrary="$(outdir)\lib\engine.lib" programdatabasefile="$(outdir)\pdb\engine.pdb" stripprivatesymbols="$(outdir)\pbs\engine.pdb" the directories "bin", "lib", , "pdb" automatically created in $(outdir) directory, "pbs" directory not. any ideas why happening? have no custom-, pre-, or post-build sections. because not stripping private symbols pdbs. you need explicitly set in property pages (linker -> debug) if want pbs versions of pdb files.

i have situation print out runs of "discount cards" unique code printed on card user can redeem on online store discount. we create many of these cards, few of them being used, i'd use form of way identify valid code using method rather storing each individual code in database. create 5,000 of these codes @ time. 5 times year. ideally i'd able like: $coupons->generate(5000, 'unique_salt', 'prefix_'); which generate 5,000 "random" codes like: prefix-23-3424-4324-3344 or prefix-4h-34re-22k3-pe3w the unique salt , prefix_ saved database. these codes able verified using prefix_ lookup salt , identify code valid or not. i have form of working using number salt, find numbers divisible salt, , reorder digits appears random. long enough codes, take work figure out pattern. i'd think there's better way... there's many numbers yield large amounts of codes divisible salt . (for example, salt of 2 yield 5,000 cod

the canonical example here twitter's api. understand conceptually how rest api works, query server particular request in receive response (json, xml, etc), great. however i'm not sure how streaming api works behind scenes. understand how consume it. example twitter listen response. response listen data , in tweets come in chunks. build chunks in string buffer , wait line feed signifies end of tweet. doing make work? let's had bunch of data , wanted setup streaming api locally other people on net consume (just twitter). how done, technologies? node js handle? i'm trying wrap head around doing make thing work. twitter's stream api it's long-running request that's left open, data pushed , when becomes available. the repercussion of server have able deal lots of concurrent open http connections (one per client). lot of existing servers don't manage well, example java servlet engines assign 1 thread per request can (a) quite expens
