so working in site sores cuneiform tablets info. use semitic chars transliteration. in script, create term list translittaration of tablet. my problem Š, script created 2 different terms because thinks there space in word because of way cake treats special char. exemple : partial contents of tablet : utu-diŠ-nu-il2 terms tablet when treated script : utu-diŠ, -nu-il2 it should : utu-diŠ-nu-il2 when print contents of array in course of treatment of contents, see : utu-di� -nu-il2 so means uncorrect parsing of text creates space interpreted in script 2 words instead of one. in database, text fine... i these errors : warning (512): sql error: 1366: incorrect string value: '\xc5' column 'term' @ row 1 [core\cake\libs\model\datasources\dbo_source.php, line 684] query: insert terms ( term , lft , rght ) values ('utu-di�', 449, 450) query: insert terms ( term , lft , rght ) values ('a�...

some of dates in column of dates recorded wrong. i'd make query subtracts 1 day each date if days in date range. i know i'll have use dateadd , update, can't seem figure out. in advance. this should it: update [sometable] set [datecolumn] = dateadd(d, -1, [datecolumn]) [datecolumn] between [date1] , [date2] here's msdn doc's on dateadd function: http://msdn.microsoft.com/en-us/library/ms186819.aspx when performing updates on data this, it's best run select statement first same criteria ensure you're updating correct records. helps reduce stress level of updating (especially if you're unfamiliar sql). select *, --depending on columns see, wildcard replaced dateadd(d, -1, [datecolumn]) proposeddate [sometable] [datecolumn] between [date1] , [date2]

i programming windows application (in qt 4.6) - @ point - inserts number of datasets between 1 , around 76000 oracle (10.2) table. application has retrieve primary keys, or @ least primary key range, sequence. store ids in list used batch execution of prepared query. (note: triggers shall not used, , sequence used other tasks well) in order avoid calling sequence x times, increment sequence x instead. what have found out far, following code possible in procedure: alter sequence my_sequence increment x; select my_sequence.curval + 1, my_sequence.nextval v_first_number, v_last_number dual; alter sequence my_sequence increment 1; i have 2 major concerns though: i have read alter sequence produces implicit commit. mean transaction started windows application commited? if so, can somehow avoid it? is concept multi-user proof? or following thing happen: sequence @ 10,000 session sets increment 2,000 session selects 10,001 first , 12,000 last session b sets increment...

eventhough write in python think abstract concept more interesting me , others. pseudocode please if :) i have list items 1 of classes. lets strings , numbers here, doesn't matter. nested depth. (its not list container class based on list.) example : [1, 2, 3, ['a', 'b', 'c'] 4 ['d', 'e', [100, 200, 300]] 5, ['a', 'b', 'c'], 6] note both ['a', 'b', 'c'] same container. if change 1 change other. containers , items can edited, items inserted , important containers can used multiple times. avoid redundancy not possible flatten list (i think!) because loose ability insert items in 1 container , automatically appears in other containers. the problem: frontend (just commandline python "cmd" module) want navigate through structure cursor points current item can read or edited. cursor can go left , right (users point of view) , should behave list not nested list flat one. for h...

i trying bind copy of datatable gridview, not display it. here sample code: var clonedata = originaldata.clone(); gvtable.datasource = clonedata; gvtable.databind(); if bind originaldata instead of clonedata, works.. what's wrong copy? asp.net c#. you need use copy() instead of clone() both copy , clone methods create new datatable same structure original datatable. new datatable created copy method has same set of datarows original table, new datatable created clone method not contain datarows. source

i have following code: var templist = new brandcollection(); if (httpcontext.current.cache["cacheddevicelist"] == null) { templist = provider.getdevicedata(info); httpcontext.current.cache.insert(...); } else { templist = } cache.insert() method overloaded can set dependencies, sliding , absolute expiration. want make cache expire @ midnight. how do that? thank in advance! absolute expiration way - it's shorthand 'this expires @ absolute point in time' opposed 'in twenty minutes now'. when put item cache, need calculate when midnight , use expiration point e.g. var templist = new brandcollection(); if (httpcontext.current.cache["cacheddevicelist"] == null) { templist = provider.getdevicedata(info); // find out when midnight taking today , adding day datetime expirationtime = datetime.today.ad...

in vb.net, there way of auto-detecting culture of string representation of number? i'll explain situation: our asp.net web site receives xml data feeds boat data. of time, number format prices use either simple non-formatted integer e.g. "999000". that's easy process. occaisionally, there commas thousands separators , periods decimal point. also, that's fine our data import understands this. example "999,000.00". we're starting data france of prices have been entered periods , thousands separators other way around that's way it's done in many european countries. e.g. "999.000,00". our system interpret 9 hundred , ninety 9 pounds instead of 9 hundred , ninety 9 thousand pounds intended. unfortunately, data feed contains prices in mixture of formats without culture indicator on each one. know of in-built .net functions auto-detect culture of string number based on period , comma are? there no built-in way determin...

i'm writing opengl game, , want native looking gui elements. wondering if has hacked gtk+ using gtkoffscreenwindow , gtk_offscreen_window_get_pixbuf render opengl texture, , whether have reasonable performance, considering repeated re-uploading of texture data every time gui updated while possible, i'd instead use real opengl widget toolkit clutter. if want render gtk+ opengl, i'd start creating new gdk backend (x11/opengl or that), (re-)implements gdk drawing functions using opengl. nice side effect be, gtk+ windows allow ordinary opengl rendering, too, i.e. no more need gtkglwidget class.
