Question
Pass javascript variable by reference to OCX
I have an OCX (developed by myself) to be used in a web page using javascript / vbscript.
I would like to pass a variable to the OCX and then change the value of the parameter inside the OCX and then pass the new value back to the JavaScript function. It would be great if the parameter can be of type string.
Is it possible to pass the address (pass by reference) of a javascript parameter to OCX.
thank you

However, your question requested changing a (preferably) string type by reference...which is not possible, last I heard. If you've got new information on this, do share. :)
If you passed a javascript object and changed a property inside the object, then that's really a different way of solving your problem but it is not a new answer to the question. :-P
Regards.
Thanks. Yes I wanted to pass a variable to an ActiveX control and then change the value of that variable inside the ActiveX control and then pass the new value back to JavaScript. What I have done now is to leave the parameter route and rather return a BSTR* from the ActiveX control function to the calling JavaScript function. So I don't think I am changing a property of the object.
Is this what you guys said I shoud I do?

No. All javascript parameters are by value only.
WScript users often have similar questions and the answer in WScript is that there is an alternate way to call a method such that the needed value is returned.
Good luck with your project!
