which better in gwt interface, using normal mvp javacode, or uibinder?? performance, editing, simplicity aspects. this google says : besides being more natural , concise way build ui doing through code, uibinder can make app more efficient. browsers better @ building dom structures cramming big strings of html innerhtml attributes bunch of api calls. uibinder naturally takes advantage of this, , result pleasant way build app best way build it. so judging points mentioned, uibinder provides more advantages. however, wouldn't everything in uibinder. start it, , you'll find out, little bit of pure code might better (or only) choice!

as title says, is y = x = x + 1; undefined behavior in c? answer question no. what happen happen: int x = 1; /* assume */ y = x = x + 1; /* results: */ y == 2; x == 2; how compiles same as: x += 1; y = x; why not undefined because not writing x in same expression read it. set + 1 , assign y value of x . your future if find code confusing can use parentheses readability: y = x = (x + 1);

i have looked @ autofills firefox. not designed developers' needs in mind. general internet surfers need tool fill in many different forms constant values each form. developers need opposite, when want test part of app you'll need fill single (or couple of) forms many times different (but valid , sensible) data. so, such thing exist? autofill fill form inputs based on perhaps class name (email, password, address, url, ...)? i feel if doesn't exist should roll sleeves , make one! 1 put in share if others want team up. right now, desperately in need of 1 if exists one way use greasemonkey. example script: "auto fill forms custom information": http://userscripts.org/scripts/show/39313 edit: link may broken i'm sure capable of finding many greasemonkey references.

in wpf 4 binding expression list on binding group, passed validationrule 's validate method, empty. it same whether autogeneratecolumns true or false, whether datagridboundcolumns explicitly has been added datagrid. in wpf 3.5 sp1 using datagrid toolkit binding expression list filled excepted binding expressions (1 each column in data grid) i consider bug , has posted on microsoft connect site: https://connect.microsoft.com/wpf/feedback/details/642815/bindingexpressions-on-bindinggroup-passed-to-validationrule-in-datagrid-rowvalidationrules-is-empty but have workaround can correct binding expression within validationrule ? in order support "proposed values" not committed target of two-way binding until validation succeeds, wpf 4.0 datagrid redesigned take advantage of the new bindinggroup.sharesproposedvalues feature of wpf 4.0. because of change, no longer necessary use two-way bindings in binding group of display templates. you can use bindi...

when create socket: socket socket = new socket(ipaddress, port); it throws exception, ok, because ip address not available. (the test variables string ipaddress = "192.168.0.3" , int port = 300 .) the problem is: how set timeout socket? when create socket, how reduce time before unknownhostexception , socket timeout? use socket() constructor , , connect(socketaddress endpoint, int timeout) method instead. in case like: socket socket = new socket(); socket.connect(new inetsocketaddress(ipaddress, port), 1000); quoting documentation connect public void connect(socketaddress endpoint, int timeout) throws ioexception connects socket server specified timeout value. timeout of 0 interpreted infinite timeout. connection block until established or error occurs. parameters: endpoint - socketaddress timeout - timeout value used in milliseconds. throws: ioexception - if error occurs during connection socke...

would safe use mysql database record positions of players on screen? then second, flash retrieves new position data in database , sets players' positions of map new positions? i'm not sure how slow be. i know php. know sql. not experienced in actionscript, can basic things set positions of objects. not know how retrieve information database via flash. not know how make flash send out queries. do think give me bit of help? it safe use mysql. but, wouldn't recommend using php + mysql game server though, or server tend lock influx of requests. http protocol not designed this. it might take bit of time, learn easy programming language (especially java or c#) create basic server. can store user information within ram, instead of accessing database repeatedly. but, have server updates database every n amount of minutes, in case server shutdown , needs started same data.

the version information, displayed when mouse cursor hovers on file in windows explorer, set file built visual studio in version resource. set version in 1 place files built solution, preferably when change version in install properties. there way this? the motivation if version not updated file, installer leave previous versions of files instead of replacing them new files. happens when 'removepreviousversions' property set. in order save tedious , error prone task of updating version in every file built , installed, remove version resource files - not elegant. the second answer in stack overflow topic how programatically change project's product version? features solution setting version number common header file in c++. place header file containing hard-coded version numbers in folder each project can find it. the above answer describes means of incrementing version number. alternate approach c++ version incrementing available microsoft's arti...
