Is it possible to run an ExtendScript function from the FDK?

Ian,

strange, we had the same question a week ago in FrameDev-Yahoo Group. So I can copy + paste:-)

There is not Chance to provide parameters with F_ApiCallClient(). One solution was to write a temporary file in your FDK Client and read this within your ES. I would recommend to write to JSON Format for more complex data structure, as you can use eval() to deserialize this data to an object model very easily.

Few year's ago, I implemented a solution with F_ApiHypertext which works very well:

In your plugin call following, where you call F_ApiCallClient now

F_Sprintf((StringT)message, "message ScriptingSupport Notification FA_Note_PreFunction: docid:<%d> sparm:<%s> iparm:<%d>", docId, sparm, iparm);
F_ApiHypertextCommand(0, message);

F_ApiHypertextCommand can be called anywhere in your script, of course. The message string doesn’t matter. You only need a rule in your script which can handle and parse this

In your script register for “Constants.FA_Note_PreHypertext” and implement Notify-callback which catches this Event

[…]
if (sparm.substring(0, “message ScriptingSupport Notification FA_Note_PreFunction:”.length) == “message ScriptingSupport Notification FA_Note_PreFunction:”)
{
    //FA_Note_PreFunction Notification was raised by fdk client
    OnHyperTextNotification(Constants.FA_Note_PreFunction, sparm) ;
}
[…]

function  OnHyperTextNotification(notification, str) 
{
    var idxDocId = str.indexOf("docid:<") + "docid:<".length;
    var idxSParm = str.indexOf("sparm:<") + "sparm:<".length;
    var idxIParm = str.indexOf("iparm:<") + "iparm:<".length;
    var docid = str.substr(idxDocId).substr(0, str.substr(idxDocId).indexOf(">"));
    var sparm = str.substr(idxSParm).substr(0, str.substr(idxSParm).indexOf(">"));
    var iparm = str.substr(idxIParm).substr(0, str.substr(idxIParm).indexOf(">"));
     //invoke Notify or do anything else
    Notify (notification, docid, sparm, iparm) ;
}

I don’t know yet, if it’s possible to get a return value back from ES to FDK.

I hope this is useful
