i when necessary prevent null pointer exception : // example #1 if (cats != null && cats.count > 0) { // } in #1, i've assumed cats != null needs first, because order of operations evaluate left right. however, unlike example #1, want if object null or if count zero, therefore i'm using logical or instead of and: // example #2 if (table == null || table.rows == null || table.rows.count <= 0) { // } does order of logical comparisons matter? or can reverse order , same results, such in example #3? // example #3 if (table.rows.count <= 0 || table.rows == null || table == null) { // } (btw, realize can rewrite #2 below, think it's messy, , i'm still curious or operators) // example #4 if (!(table != null && table.rows != null && table.rows.count > 0)) { // } yes, short-circuiting happens in both cases, difference being && stops if lhs false (because overall expression must false) while || ...

is true asp.net mvc doesn't use sessions [sessions varibale] , hence there it's performance better asp.net webform. if not case why speed of asp.net mvc faster asp.net webform? it's not use viewstate ,since viewstate data doesn't transmit , fro between client , server,the mvc pages load bit faster.

how can evaluate string in c# windows application because need dynamically select object in form based on combination of 2 string give me name of needed object you can try controlcollection.find method find control name. example: myform.controls.find("foobutton", true); method returns array of control element name property set "foobutton". there no c# eval equivalent . link can find useful answers. ofc, if want find or evaluate winform controls update: think better control key directly. example: control control = this.controls["footxtbox"]; if(control==null) { messagebox.show("control not found"); } control.text = "something";

let's manage multidimensional array (pseudo-code): array $colors * wine,red * cheese,yellow * apple, green * pear,brown what code used avoid following notation, initialize array (assuming there hard-coded list of elements=?: $colors[x][y] = 'something'; $array = array( array('wine', 'red'), array('cheese', 'yellow'), array('apple', 'green'), array('pear', 'brown') ); upd: foreach ($array $v) { echo $v[0]; // wine, cheese... echo $v[1]; // red, yellow... }

first of all, state facts know 'inline', don't bother restate them. an inline function special kind of function definition must available in every translation unit in function used. it hint compiler (which free ignore) omit function call, , expand body instead of call. the pro know of (2.) may make code faster. the con know if (1.) increases coupling bad. now let's consider templates. if have template library, need provide definitions of function templates in every translation unit, right? let's forget controversial 'export' while, since doesn't solve problem anyway. so, come conclusion there no reason not make template function inline because con of inline know of there priori. please correct me if wrong. in advance. the pro know of (2.) may make code faster. may being operative word. inlined functions may make code paths faster, yes. but inlined function puts additional pressure on instruction cache on modern cpus. i...
