service - How to catch specific Exception in VB.NET -


vb.net 2010, framework 3.5

not catch exception identify type of error is. create error write pc's event log when event log full. sample below throws system.componentmodel.win32exception. that's great , doesn't tell me 'event log full', other errors encompassed system.componentmodel.win32exception. safe @ errorcode = -2147467259 or nativeerrorcode = 1502 determine event log full?

sub main()     try          while true ' loop overflow event log             eventlog.writeentry("source", "message")         loop      catch w system.componentmodel.win32exception         if w.errorcode = -2147467259             ' errorcode = -2147467259 when event log file full?         end if         if w.nativeerrorcode = 1502             ' nativeerrorcode = 1502 when event log file full?         end if         if w.message = "the event log file full"             ' code event log full         end if          if w.errorcode = -2147467259             if w.nativeerrorcode = 1502                 if w.message = "the event log file full"                     ' code event log full if 3 conditions true?                  end if             end if         end if     end try end sub

java - IntelliJ - No such instance method -

using intellij's 12 ultimate, i'm running following code in debugger: java import play.api.libs.json.jsvalue; public class foo { ... public jsvalue tojson() { ... } public class fooexample { ... foo foo = new foo(); system.out.println("...); //<-- breakpoint at breakpoint, right-clicked source code , picked "evaluate expression," typing in: foo.tojson() . but following error showed up: no such instance method: play.api.libs.json.jsvalue$class.com.foo.foo.tojson () am doing wrong? foo#tojson calls scala code, if matters. edit had breakpoint after instantiation of foo. downvoted it, deserved it. edit my answer no longer valid after op modified question (i.e. moved breakpoint actual is).. a breakpoint hit before line executed. in case foo has not yet been declared or instantiated (i.e. foo constructor has not yet been called). you'll need put breakpoint @ next line (or step on current line) if want evaluate foo .

[dom] the value must unique amongst ids in element's home subtree , must contain @ least 1 character. the value must not contain space characters. note: there no other restrictions on form id can take; in particular, ids can consist of digits, start digit, start underscore, consist of punctuation , etc. note: element's unique identifier can used variety of purposes, notably way link specific parts of document usin
