c# - Stop WPF animation, storyboard begin in xaml but stopping it in codebehind? -

-

i created animation storyboard in xaml file. story board begins on button.click. stop animation trying stop storyboard on custom event in code behind. code not throwing exception when event got fired animation still goes continue.

i think issue stop method. stop required same object begins animation stop it. here storyboard begin in wpf xaml , stopping in code behind.

any solution, how xaml object in code behind or alternative solution this??

xaml code:

<canvas.triggers>             <eventtrigger routedevent="button.click" sourcename="scanbutton">                 <eventtrigger.actions>                     <beginstoryboard >                         <storyboard  name="movingserver" storyboard.targetname="imagemove" repeatbehavior="forever" >                             <doubleanimation storyboard.targetproperty="(canvas.left)" duration="0:0:2" from="30" to="300" begintime="0:0:0" />                             <doubleanimation storyboard.targetproperty="(canvas.left)" duration="0:0:5" from="300" to="300" begintime="0:0:5" />                             <doubleanimation storyboard.targetproperty="(canvas.left)" duration="0:0:2" from="300" to="600" begintime="0:0:7" />                             <doubleanimation storyboard.targetproperty="opacity" duration="0:0:2" from="1" to="0" begintime="0:0:7" />                         </storyboard>                     </beginstoryboard>                 </eventtrigger.actions>             </eventtrigger>

code behind:

    private void eventpublisher_onscanningfinish(object sender, eventargs args)     {         dispatcher.invoke(dispatcherpriority.normal, (action)delegate() { this.stopscanninganimation(); });     }      private void stopscanninganimation()     {          serverview.storyboardserverscrolling.stop(this); //---------- not working          //this.serverview.server1static.visibility = system.windows.visibility.hidden;         //this.serverview.server2static.visibility = system.windows.visibility.hidden;         //this.serverview.server3scrolling.visibility = system.windows.visibility.hidden;         //this.serverview.searchingglass.visibility = system.windows.visibility.hidden;     }

define storyboard static resource, 

<mycontrol.resources>                         <storyboard key="movingserver" storyboard.targetname="imagemove" repeatbehavior="forever" >                             <doubleanimation storyboard.targetproperty="(canvas.left)" duration="0:0:2" from="30" to="300" begintime="0:0:0" />                             <doubleanimation storyboard.targetproperty="(canvas.left)" duration="0:0:5" from="300" to="300" begintime="0:0:5" />                             <doubleanimation storyboard.targetproperty="(canvas.left)" duration="0:0:2" from="300" to="600" begintime="0:0:7" />                             <doubleanimation storyboard.targetproperty="opacity" duration="0:0:2" from="1" to="0" begintime="0:0:7" />                         </storyboard> </mycontrol.resources>

and reference backend code follows :

storyboard board = (storyboard)this.findresource("movingserver"); board.stop();

start animation 'click' event of button (i don't know if defined in xaml, here's how done if did)

<button x:name="scanbutton" onclick="scanbutton_click"></button>   protected void scanbutton_click(object sender, eventargs e) {     storyboard board = (storyboard)this.findresource("movingserver");     board.start(); }

php - What is the difference between $_SERVER['PATH_INFO'] and $_SERVER['ORIG_PATH_INFO']? -

what’s difference between $_server['path_info'] , $_server['orig_path_info'] ? how use them? when run print_r($_server) , path_info , orig_path_info not present in array. why not? how can enable them? i have read php manual on them, still don’t understand them. the path_info variable present if invoke php script this: http://www.example.com/phpinfo.php/hello_there it's /hello_there part after .php script. if don't invoke url that, there won't $_server["path_info"] environment variable. the porig_ prefix uncommon. path_info standard cgi-environment variable, , should never prefixed. did read that? (there issues around php3/php4 if invoked php interpreter via cgi-bin/ - hardly has such setups today.) for reference: http://www.ietf.org/rfc/rfc3875

fortran - Function return type mismatch -

i'm attempting recode old c++ program in fortran make use of lapack (i'm aware c++ have lapack++, i'm having lot of trouble installing it, gave up). i didn't have problems compilation, when had variables declared real . when started coding section of program required lapack, found parameters passed dsyev need double precision . tried change double precision (including changing hard coded numbers double precision counterparts, i.e. 0.0 -> 0.0d0) when try compile, following error of functions , subroutines i've written: error: return type mismatch of function <function> @ (1) (real(4)/real(8)) i'm not sure coming from, in program has been changed double precision. for example, i've declared following: double precision :: alpha(3),d(3),zeta1,zeta2 double precision :: a1(3),a2(3),d1(3),d2(3) double precision :: pi pi = 3.14159265359d0 alpha = (/0.109818d0, 0.405771d0, 2.22766d0/) d = (/0.444635d0, 0.535328d0, 0.154329d0 /) 10 i=1,3 ...

queue - mq_receive: message too long -

-
i implementing communication between 2 processes using queue. problem when call function mq_receive, error: message long. i have done following: struct mq_attr attr; long size = attr.mq_msgsize; .... // initializing queue "/gateway" int rc = mq_receive(gateway, buffer, size, &prio); if print size value, size=1, while when print same size program (got same mechanism), not long integer ( -1217186280 )... how can solve error?....so while size = 1, believe it's right "message long" why 1? p.s. have tried put : int rc = mq_receive(gateway, buffer, sizeof(buffer), &prio); but no result. it seems need read docs more carefully. when call mq_receive should pass size of destination buffer. this size must greater mq_msgsize attribute of queue . in addition, seems have error in queue attributes initialisation makes proper mq_receive call impossible. here standard message queue session: fill mq_attr struct ( doc ): struct mq_a...
