code near-identical blocks makes me cringe. plus adds have thousand lines of code half suffice. surely there way make loop make happen , not have code looks unsophisticated , brainless. offhand seems adding code seek reduce: loop make 5 buttons, array of labels buttons, array of backgrounds... maybe more. if turned out acceptable, how make loop handle listeners? i can't have array of methods, can i? guess such loop have include switch . yes? i'd if didn't want seek better solution. i'm asking... what code listen entire group of buttons , take action based on 1 pressed? component assign single listener? , how? (there's chance answer question make me cringe more repetitive nature of code, if realize know how , needn't have asked in first place, i'm asking anyway. i'm @ 1 of i've-had-it-for-today points brain wants out.) private void makescoremasterbonuses(){ pnlbonuses = new jpanel(new gridlayout(1, 6)); pnlbonuses.setsize(6,1); ...

i need match regex uses backreferences (e.g. \1) in go code. that's not easy because in go, official regexp package uses re2 engine , 1 have chosen not support backreferences (and other lesser-known features) there can guarantee of linear-time execution, therefore avoiding regex denial-of-service attacks . enabling backreferences support not option re2. in code, there no risk of malicious exploitation attackers, , need backreferences. what should do? regular expressions great working regular grammars, if grammar isn't regular (i.e. requires back-references , stuff that) should switch better tool. there lot of tools available parsing context-free grammars, including yacc shipped go distribution default. alternatively, can write own parser. recursive descent parsers can written hand example. i think regular expressions overused in scripting languages (like perl, python, ruby, ...) because c/asm powered implementation more optimized languages itself, go is...

i have code this: foreach (datarow row in datatable.rows) { if ((string)row["forename"] != record.forename) { // } } works great if row["forename"] null in database, dbnull here , can't cast dbnull string, or perform comparison between dbnull , string . values nullable<int> , , can't compare dbnull int? is there helper method let me nice comparisons or have write extension method myself? you can use datarow.field extension method supports nullable types: foreach (datarow row in datatable.rows) { int? id = row.field<int?>("id"); if(id.hasvalue) { console.write("id: " + id.value); } } since string reference type null default. can use datarow.isnull instead check whether dbnull.value or not: foreach (datarow row in datatable.rows) { if(row.isnull("forename")) { // ... } else { string for...

i can't dynamic method on expandoobject directly callable in vb.net. in c# following works: dynamic obj = new system.dynamic.expandoobject(); var called = false; obj.forcerefresh = new action(() => called = true); obj.forcerefresh(); i'd have thought same thing in vb.net be: dim called = false dim obj object = new dynamic.expandoobject obj.forcerefresh = new action(sub() called = true) obj.forcerefresh() 'no default member found type 'action'. obj.forcerefresh.invoke() 'this works the obj.forcerefresh throws 'no default member found type 'action' it works if put invoke, that's not option (this simplified example of moq unit test, objects being tested call functions can't change them) is there way of setting dynamic method in vb.net can call without invoke? there doesn't seem way around - need use "invoke" call dynamically-added methods in vb. the following microsoft link showing c# vs vb ...
