c# - Attach Image/ImageBrush from code behind -

-

i'm trying add image background of usercontrol. depending on value of variable need change background whatever path or uri format use, background not change.

i've seen lots of questions here in stackoverflow none fixes single problem. let code below:

            if (callback.liveuvis.containsuvi(uvi))             {                 this.status.text = "live";                   imagebrush imgb = new imagebrush();                 bitmapimage btpimg = new bitmapimage();                                     btpimg.urisource = new uri(@"///img///live///bck_frame_info_video_live.png", urikind.relative);                 //imgb.imagesource = new bitmapimage(new uri("~/img/live/bck_frame_info_video_live.png", urikind.relativeorabsolute));                 //imgb.imagesource = new bitmapimage(new uri("ms-appx:///img/live/bck_frame_info_video_live.png"));                 imgb.imagesource = btpimg;                 this.background = imgb;             }

i'm facing same problem when trying attach image... guess it's uri format also, let code in case :)

    private void seticon_desc(string dd)     {         try         {             image img = new image();             img.source = new bitmapimage(new uri(this.baseuri, "img/pictos_small/white/160dpi/" + dd + ".png"));             img.stretch = stretch.none;             this.icon = img;             this.sport.text = callback.disc.getdescription(dd).toupper();         }         catch(exception ex)         {             callback.exception.writeexceptions(ex);         }      }

thanks in advance!

i can reproduce issue when changing background of user control.

the current workaround used changing background of root uielement in control.

<grid x:name="container">     <grid.background>         <imagebrush stretch="fill" imagesource="images/bg-blue.png"/>     </grid.background>     <stackpanel>         <textblock>hello world</textblock>         <button click="button_click">change background</button>         <image x:name="display"></image>     </stackpanel> </grid> 

public sealed partial class myusercontrol : usercontrol {     public myusercontrol()     {         this.initializecomponent();     }      private void button_click(object sender, routedeventargs e)     {         imagebrush imgb = new imagebrush();          bitmapimage btpimg = new bitmapimage();          btpimg.urisource = new uri(@"ms-appx:///images/bg-light-blue.png");          imgb.imagesource = btpimg;          container.background = imgb;     } }

suddenly have started receiving above error without changes having been made script. host 1and1 (i know...) the script still works fine on different server, , suspicion there must have been server config change has lead this, although hosts plead ignorance. there's no information on above error @ in google can find - have ideas? server running apache if helps. had similar problem. came out of blue. no php code changed. what changed: php upgraded 5.5.25-1 5.5.26. a security risk in php mail() function has been fixed , newlines in additional_headers allowed no more. because newlines mean: starts email message (and surely don't want inject newlines through headers followed evil message). what have worked fine, e.g. having newlines after headers or passing whole message additional_headers , function no more. solution : sanitize headers. no multiple newlines in additional_headers argument. these count "multiple or malformed newlines":...
