c# - How to handle a BitmapImage when giving a image URI that doesn't exist? -

-

I am trying to download an image and it is a source of a bitmap image I'm setting in But there is potentially a case where the image does not exist, that is, the reaction is a 404. I am currently doing this: 

  Bitmap image bitmap image = new bitmap image (new yuri ("link_ to_ iTage"));   
 Although there is no error, I prefer to show the message or something instead of handling the case and displaying a blank code  BitmapImage  Is there a way to get the code? Or is there a different approach?   
 
 
 Subscribe to the bitmap image. accident. The reason for the failure can be read from the event handler.

php - proc_open Too many open files in long running Symfony Console app -

-
I have created a console app with a SIM console console component. It was going to run for 5 hours but after running 2 hours I have a proc_open (): Many open files in the pipeline error Symfony \ Component \ Console \ Application.php On-line 985. I tried to gc_collect_cycles in my code, but got the same error. Is this a Symphonic Console component bug or should I not run any app for this long time (but I have to)? This problem relates to: Obviously you have many resources in your app It's not a symphony console bug, but it's a PHP bug. You can modify your program by using another programming language to open fewer files.
