2. I need to create a Custom Property and set it to ValueX ONLY if it doesn't already exist, if it does exist then I want it to be left untouched.
So for number 1, I just need to set the Custom Property, but for number 2, how can I tell if the Custom Property exists?
An existing property returns a value. So you could ask for it like this: get the MyCustomProp of this stack if it = emtpy then //does not exist or is empty end if
Of course this does not help when you have lots of empty properties that you want left untouched. Alternatively you could thus get the customKeys, and query if your property is already there:
get the customKeys of this stack
if MyCustomProp is not among the lines of it then // no such property
end if
Also, what is the intended use of the "customKeys" and what does it actually save in "myCustomKeys" after executing this line:
put the customKeys of this stack into myCustomKeys
Specifically, does it return a list/array or a string or what? How Can I appended to it and then set is back again using the following line:
set the customKeys of this stack to myCustomKeys
The customKeys is a list of items, delimited by lineendings. So if you want to append something you would do it like this:
put the customKeys of this stack into myCustomKeys put return & "myNewCustomProp" after myCustomKeys set the customKeys of this stacj to myCustomKeys
Thanks a lot, what is the item delimiter for this list? Is it always the same an all lists? I typed in "list" and "array" in the Transscript Dictionary, but there is nothing there that tell me anything, even though when looking at commands (like "customKeys") it mentions things like "propertylist". Just wish they would give a definition of the parameters in commands etc.
Thanks a lot Dave _______________________________________________ use-revolution mailing list [EMAIL PROTECTED] http://lists.runrev.com/mailman/listinfo/use-revolution
