Yes, you can write an ActiveX in VB that exposes a method to retrieve any "dynamic" values you need.
Let's assume you want somethign simple so we won't invent "optimum" methods of sharing data.
Instead we will rely on registry.
So ActiveXObject would expose two methods StoreValue and ReadValue. The values would be stored
in registry. Then AFL side would invoke ReadValue, while automation side (JScript) would invoke StoreValue.
Very easy to do in VB alone.

So you're saying that an activex could be written that could do the things Mark wanted to do? In VB? If not what language would be required, C?

Hello,
I am always amused by the fact that people are so afraid of things that are pretty easy in fact provided that one just gives it a try.
If one knows how to write JScript, it is perfectly capable of writing ActiveX or even DLL plugin.
Writing ActiveX is covered in detail step-by-step procedure in the User's Guide and it does not exceed capabilities of anyone who can write JScript scripts.
http://www.amibroker.com/guide/a_aflcom.html ("Using external COM/ActiveX objects in AFL") and it is definitely easier than flying esp. by flapping your arms :-)

I was trying to convey the message that if you don't know how to write a dll or an ActiveX then you might as well try to fly by flapping your arms. I guess my attempt failed....

My answer was not supposed to be funny. I pointed out real possibilities/solutions that are far better/faster/more robust than sending keystrokes.

Or... you can write a DLL plugin.
Or... write an Active X
Or... store your "dynamic" values in database and access them via ODBC plugin

The way you describe is not that bad actually.
A more efficient way would be to use "AutoIT" www.autoit.com to click the buttons for you and enter the text. It has an activeX component as well as a dll that you could use within your script or you could call an exe that it can build.

Thanks dingo:
I am wondering what's the best way to pass parameters to a formula dynamically from JScript.
A way to do it is through a file: the script writes some dynamic values to a file and the AFL formula will reads and parses the file.
However, this would be slow and cumbersome.
Any suggestion will be appreciated,
- Mark

I am writing an automation script but couldn't find a way to set values for Param/ParamStr/ParamDate etc. I can only use their default values.
Is there a way to set their values in JScript?
Thanks,
