vb.net - Convert InvokeRequired to Dispatch in VB WPF -


hello i'm stuck on last section of code in i'm converting standard vb vb wpf using invoke commands i'm struggling use them within vb wpf. i'm on final 2 lines can't seem figure out how rewrite it, possibly help?

 if me.invokerequired         me.invoke(new methodinvoker(addressof accesspicture))

i'm using vb wpf

you can know if invocation required checking if current thread ui thread , invoke dispatcher thread if it's required here give example in c# , it's totally same logic in vb 

public void eventhandler(object object,eventargs e) { if (this.dispatcher.thread != system.threading.thread.currentthread) {  // invoke using this.dispatcher.invoke(new eventhandler(eventhandler),object,e) } else {    //execute code }  }

Unlimited choices in BASH case statement -

consider simple bash snippet: case $option in 1) image=${options[0]%.tar} ;; 2) image=${options[1]%.tar} ;; 3) image=${options[2]%.tar} ;; 4) image=${options[3]%.tar} ;; *) echo "invalid option" exit 1 esac in real script numbers goes 30. makes pretty long. can somehow specify cases variable? something this: case $option in $i) image=${options[$(($i-1))]%.tar} any pointer appreciated. you can match against multiple patterns in single clause: case $option in 1|2|3: echo "$option one, 2 or three" ;; esac if still typing you, can use simple pattern matching: case $option in # following matches # - single-digit numbers 0-9 # - two-digit numbers starting either 1 or 2 # - number 30 [0-9]|[12][0-9]|30) image=${options[$(($option-1))]%.tar} ;; *) echo "invalid option" 1>&2 exit 1 esac
