i have dollar amount in database column. can place data in column based on whether or not amount negative or positive, produces "0.00" in false column. how leave column blank? the code have follows. dim query = t in ds.hnbsavings order t.date descending, t.id descending select t.id, t.date, t.desc, debit = if(t.amount >= 0, t.amount, 0), credit = if(t.amount < 0, t.amount, 0) dgbank.itemssource = query.tolist() so results 5.0000 under debits if it's positive , 0.0000 under credits functionality works, results little difficult read. i have tried changing false declaration null, , works returns 1.0000 in false column. changed empty string " ".tostring(), runtime exception. thanks in advance. you returning numbers if(...) statements , there no such thing blank number. closest 0, why see result. return strings instead can show empty string. dim query = t in ds.hnbsavings order t.date desce

i thinking of using template engine generate web.xml , other things. is there way to run java file or script before maven install command ? or before war generated. i not sure phase should be, before else looks @ web.xml can touch make new valid one . you can use exec-maven-plugin run either program/script (using exec goal ) or java program (using java goal ). the phase before package prepare-package (see default lifecycle in lifecycle reference ), use that. might prefer generate web.xml earlier in lifecycle (even generate-resources ). putting these together, might try this: <plugin> <groupid>org.codehaus.mojo</groupid> <artifactid>exec-maven-plugin</artifactid> <version>1.3.2</version> <executions> <execution> <phase>prepare-package</phase> <goals> <goal>exec</goal> </goals> </execution> </exec

i have think should simple design i'm having trouble coming solution doesn't involve rtti (or methods return type). have generic shape interface contains pure virtual draw method only. elsewhere in program, have vector of pointers shapes, , invoke draw call on each shape. now, extend functionality of shape allow shapes compare 1 , return whether or not overlap. obviously, code depends on specific type of subclass of shape -- is, code determine whether 2 circles overlap different code determine whether circle , rectangle overlap. right now, using typeid followed dynamic cast dispatch 2 objects correct overlap code, seems kludgy. there pattern or technique can use avoid use of typeid , static_casts?

i've seen in great ko manual example of creating new class within self invokation function, in way "should not pollute global namespace". not understand why send myapp (the current namespace) "inner scope", if anyways existed in outer scope. far know, if send object js function, passed ref, change reflected outside of function either. why 'injecting' myapp inside? : window.myapp = {}; (function (myapp) { function product() { var self = this; self.sku = ko.observable(""); self.description = ko.observable(""); self.price = ko.observable(0.00); self.cost = ko.observable(0.00); self.quantity = ko.observable(0); } myapp.product = product; }} (window.myapp)); thanks !!! i can think of these reasons scope variable. let minifiers replace variable shorter name inside function. keep reference original object if global variable overwritten. prevent local variables

one of constructors shown on msdn , takes int32 parameter representing initial capacity. there remark on above documentation page states following: if count less capacity of stack, push o(1) operation. if capacity needs increased accommodate new element, push becomes o(n) operation, n count. pop o(1) operation. i'm in situation don't know how initial capacity give stack. better overestimate think need ? because surely low initial capacity make performance suffer? what drawback in passing in high initial capacity in terms of performance? internally, storage array inside stack<t> grows exponentially , implies amortized o(1) cost add element . so, if don't know correct initial capacity, don't worry , use default constructor , performance anyway.
