As the WebDriver UDF - Help & Support thread has grown too big, I started a new one. The prior thread can be found here.

No problem, $aArray[0] creates an empty array, you were using $aArray[1] which was creating an array with a single element/row, by default all variables are strings so that one element translated into an empty string, this is why you were seeing a single "" in the outputted JSON

No junkew, It's definitely not just a matter of personal preferences. AddPropertyChangedEventHandler can detect hundreds of property events per second from multiple properties. Your code cannot.

trying to work up a simple example...

kartune, You have sets of variables containing the control id's of sets of controls that you wish to manipulate as a set without repeating code for each individual variable in each set. When you create a control that you wish to manipulate you create a corresponding control id. That control id can be stored in a simple variable, e.g. $myctl = something or in an array, e.g. $checkbox[$1] = something. The problem you have is program organization, in that you need to manage control id's in sets. Arrays are perfect for that. Without example code or more detail I can't really comment in more detail. I would caution you to stay away from eval/assign if possible. Good Luck, kylomas

Could it be that the linux is refusing the connection? What is the result in $code1?

you can do assignments with variables, if this is headed down your mental path we probably just need to work out where in your script it would best suit, which depends a lot on how you are initially creating the controls and storing IDs as @kylomas inquired. for $i = 1 to 3 assign("var" & $i , $i) next msgbox(0, '' , eval("var1")) msgbox(0, '' , eval("var2")) msgbox(0, '' , eval("var3"))

Advantages using the CLR UDF are mainly no depencies needed. When compiling your Au3 scripts you can have everything in 1 EXE and it will be very portable to other machines... When using the commandline you need to involve 2 dependencies I have not compared speed between the 2 approaches though ... ?
