microsoft's visual basic 1 of first languages started learning, , helped build interest in programming. recently, have been reading around language impractical or considered joke. i've been branching out other languages, java. in long run, worth me keep using visual basic write applications? or should move on , try , learn language. main interest developing gui applications, why liked visual basic because creating gui extremely easy. "visual basic joke" , old cliche no longer actual. visual basic.net first-class citizen .net platform , @ end produces same managed code c# , other clr languages. so if have used vb before - continue using vb.net, keep in mind has full support oop (inheritance, encapsulation etc.) while can simple migrate old code vb.net - learn new capabilities , use them.

this scenario apply whole bunch of ui widgets, simple example i'll use slider (e.g. jquery ui slider). i have jquery slider notifies backbone.model when 'slides' when stops. views update in both cases. want add undo/redo functionality listen changes in model, , create undo objects each change, using previous() values. however, want create undo objects when slider stops, not on every change during sliding. so, need slider notify model of changes slider value in 2 different ways can distinguished undo code. at moment, i'm doing model.trigger('slidevalue', [newvalue]) while sliding , views listen , update on trigger. when slider stops, model.set('slidevalue', newvalue) , undo functionality listens these change events create new undo object , add queue. the reason i'm doing model.trigger('slidevalue', [newvalue]) allows me notify views model changing (so can render change), when come model.set('slidevalue', newvalue) when slid...

i having issue trying select specific columns exec statement on stored procedure. trying find count(*) stored procedure returns doing : insert #temp exec dbo.my_sp set @count = (select count(*) #temp) delete #temp however, works if columns returned match table columns , since trying find count of many different stored procedures (each of return different columns), cannot use method without creating new table each stored procedure. is there way can select specific columns exec dbo.my_sp ? would @@rowcount work you? if object_id('someproc') null exec ('create procedure dbo.someproc select 1 somevalue union select 2 somevalue;') exec dbo.someproc select @@rowcount rowsaffected http://technet.microsoft.com/en-us/library/ms187316(v=sql.105).aspx

how multiply 2 64-bit integers 2 64-bit integers? didn't find instruction can it. you need implement own 64 bit multiplication routine using 32 bit multiply operations. it's not going more efficient doing scalar code though, particularly there lot of shuffling of vectors required operations.

my question regarding ftpclient . need detailed reply statistics. when use getreplystring() part of information. example: code is ftpclient ftp = new ftpclient(); //some code here ftp.storefile(hostdir + filename, input); system.out.println(ftp.getreplystring());// prints "226 transfer ok" when sucessful but need statistics when ftp manually using command prompt in 226 transfer ok ftp: 50 bytes sent in 0.09seconds 0.55kbytes/sec. how these stats using ftpclient? idea or link refer to? you can make manually, recording start , end of process. after, calculations, like: filelength / timeend - timestart. should work little more in these calculations.
