i have specified columns searchable through colmodel , can't find way specify default column when search box opened. any appreciated. there option columns not documented in the list of searching options . wrote the answer , the demo demonstrate how can implement requirement. updated : if use multiplesearch: true option can follow referenced answer , specify columns option described. corresponding demo find here . if don't multiplesearch: true option don't display searching rule per default can add default rule in filters property of postdata . example the next demo identical previous 1 uses additionally postdata: { filters: {groupop: "and", rules: [{field: "amount", op: "eq", data: ""}]} } option. if don't want use multiplesearch: true option 1 have fix small bug in jqgrid able use columns option. 1 have modify the lines (see line 7009 in jquery.jqgrid.src.js ) from } else { columns = p....

i've got multiple rows in result query: for example, table "extras": id_extras - id_order - id_size - name_extra - price 1 1 3 teddy 4 2 2 8 balloon 8 3 2 9 wine 2 4 2 1 choco 9 5 6 1 bag 4 what want is: id_extras - id_order - id_size - name_extra - price - name_extra1 - name_extra2 - price1 - price2 1 1 3 teddy 4 2 2 8 balloon 8 wine choco 2 9 3 6 1 bag 4 so need name_extra , price in columns instead of rows, have now. select * , max(case when id_order = id_order name_extra else null end) name_extra1, max(case when id_order = id_order name_extra else null end) name_extra2, max(case when id_order = id_order price e...

there known issue ios safari ignore content-disposition: attachment headers. big problem when trying trigger downloads single page application (i'm using iframe hack open suggestions if has others). i can test ios directly: var iosmobile = (function(useragent){ return !!(useragent.match(/ipad/i) || useragent.match(/iphone/i) ); })(window.navigator.useragent); but i'd rather not browser-sniff. know how can feature detect whether content-disposition handled properly??

what trade-offs, advantages , disadvantages of each of these implementations ? different @ ? want achieve store vector of box'es, protobuf. impl 1 : package foo; message boxes { message box { required int32 w = 1; required int32 h = 2; } repeated box boxes = 1; } impl 2: package foo; message box { required int32 w = 1; required int32 h = 2; } message boxes { repeated box boxes = 1; } impl 3 : stream multiple of these messages same file. package foo; message box { required int32 w = 1; required int32 h = 2; } 1 & 2 change / how types declared. work identical. 3 more interesting: can't just stream box after box after box , because root object in protobuf not terminated (to allow concat === merge). if only write box es, when deserialize have 1 box last w , h written. need add length-prefix; arbitrarily, but: if happen choose "varint"-encode length, you're close repeated gives - except repeated i...

i want create function (symfun), , want divide cases, i.e if t> then answer , if t<0 answer b. thing is, matlab wont allow me put if statements after sym function. >> l = symfun(0, [m]); >> l(m) = if m>0 3 also tried create function: function [x1] = xt_otot_q3(t) and tried connect between 2 functions: >> l(m) = xt_otot_q3(m) conversion logical sym not possible. is there way break symfun cases? not sure understand want. code 'combines' functions symfun , xt+otot_q3 defined below: function test; m=randn(4); % n(0,1) random numbers l=xtotot_q3(symfun(0,m)) % combine xt_otot_q3 , symfun l=symfun(0,xtotot_q3(m)) % combine symfun , xt_otot_q3 return function lval=symfun(thr,rval); lval=ones(size(rval)); % output, size of input, = 1 lval(rval<thr)=-1; % output = -1 if input < thr return function lval=xtotot_q3(rval); lval=3*rval+1; % function, in case 3 * input + 1 re...

i'd reference .ts file in .ts file. in real project, need type safety (overriding inherited member correct compilation). my sample: test1.ts: export class test1 { } test2.ts: /// <reference path="test1.ts" /> export class test2 { abc: test1; // error: test1 not found } is not possible? i'd avoid importing overhead don't need in outputted javascript file. update: use test1 amd module class test1 instanciated , injected instance of class test2 underlying framework. why need export keyword don't want directly import module type1 - need reference class avoid compiler errors , have type safety etc.. without using module loader the export keyword @ root level of file relevant if using module pattern (amd / commonjs). if not following work: test1.ts: class test1 { // not use export } test2.ts: /// <reference path="test1.ts" /> class test2 { abc: test1; // no error } however if responsible ensur...

i making 2d game ios using kobold2d/cocos2d. i've decided try , add 3d buildings (think gta1/2 2d except buildings). i know how opengl works im getting sorts of errors when try implement this. my questions is: cocos2d prevent me using normal opengl calls ?,or should work fine if done correctly? every tutorial/example i've found uses cocos2d wrapper mixing opengl , cocos.. if have done before (mix own opengl es 2.0 code cocos2d) point me in right direction? as long you're using cocos2d/kobold2d v2.x can use opengl es 2.0. can override/implement ccnode class' -(void) draw method , hack away. there's 1 caveat: should prefer use cocos2d provided "ccstuffstuff" methods (for example ccdrawcolor) instead of opengl es methods because wrap behind scenes stuff performance reasons , compatibility. check existing cocos2d drawing code examples. 1 such example gles-render.cpp cocos2d+box2d projects, or ccdrawingprimitives.m file.

so given database , im trying solve trigger bug (it's pretty small change) i've looked @ every function/trigger did a: select * sys.triggers name = 'name' and returned this: name 1181247263 1 object_or_column 2053582354 tr sql_trigger 2012-11-13 09:41:13.707 2013-03-19 14:08:22.583 0 0 0 0 what mean? there literally folder/function called object_or_column because can't see it? im doing in sql server management studio btw. this tell associated table... select t.name triggername, ss.name schemaname, so2.name tablename sys.triggers t join sysobjects on t.object_id = so.id join sysobjects so2 on so.parent_obj = so2.id join sys.schemas ss on so2.uid = ss.schema_id t.name = 'name'
