i'm using js-data (and js-data-angular) in conjunction sockets via sails.js. when new item created/updated via sockets want call attention in ui. i'd add "updated" property object, don't want inadvertently persist db. is there way hang non-persisting properties on js-data object? yes. you can set globally on data store or per-resource using omit configuration setting. instance, when instancing data store, can instruct jsdata ignore properties begin underscore: var store = new jsdata.ds({ omit: [ /^_/ ] });

i'm writing vba functions in excel compute word values , cross sums of input. i'm passing input public function cross_sum(myrange range) integer them take cell references input, e.g. =cross_sum(a1) . works fine. however when try chain 2 functions =cross_sum(word_value(a1)) run th value error because word_value() returns integer value , not range cross_sum() set expect. did not find way cast integer (or string) range. as excel's built-in functions support chaining range input wonder how. unfortunately first vba project wonder if , how cast or type choose working both ways. any pointers appreciated! tia, jbq you can pass variant function , function can determine type of input: public function inputs(v variant) string if typename(v) = "range" msgbox "you gave me range" else msgbox "you gave me string" end if inputs = "done" end function sub main() dim st string dim

i think i'm missing fundamental nullable types. example open new understanding, @ least, maybe can 1 thing working right. in class (a dialog form), declare: property productstructureheaderkey int32? in class, declare instance of dialog , attempt set property line: dr.productstructureheaderkey = if(parentrow.cells(1).value nothing, nothing, int32.parse(parentrow.cells(1).value)) when line assigns nothing property, property equal 0. (and later, it's passing 0 db when want passing null.) that's not expect , keep finding code (so, msdn, etc) looks i'm doing things right, clearly, i'm not. so, friends, doing wrong? how employ nullable types meet needs? that's 1 of differences between c# , vb.net. in vb.net nothing not mean null default . assigning default value of int32 property 0. caused if -operator has infer type 2 values not property want assign. instead use either if...else : if parentrow.cells(1).value nothing dr.product
