Question

How to pass Java script parameters into DispatchScriptRunner() Function.
Tried Code:
WideString scriptPath("InDesign\\CS5\\scripting\\indesign\\samplescripts\\JavaScript\\AddGuides.jsx" );
          IDFile scriptFile(scriptPath);
          InterfacePtr<IScriptRunner>scriptRunner(Utils<IScriptUtils>()->QueryScriptRunner(scr iptFile));
          if(scriptRunner)
                     ScriptRecordData arguments;
                     ScriptIDValuePair arg;
                     ScriptID aID;
                     ScriptData script(scriptFile);
                     ScriptData resultData;
                     PMString errorString;
                     //To add pair into KeyValuePair
                     KeyValuePair<ScriptID,ScriptData> ScriptIDValuePair(aID,script);
                     arguments.push_back(ScriptIDValuePair);
                     int length=arguments.size();
                     PMString str;
                     str.AppendNumber(length);
                     //CAlert::InformationAlert(str);
                     Utils<IScriptUtils>()->DispatchScriptRunner(scriptRunner,script,arguments,resultData,erro rString,kFalse);
Value of ScriptId is cuming null or (0);
Please provide a solution to get a scriptId
Qn 2. How to pass a particular Java script methd's parameters into DispatchScriptRunner() Function in c++ code.

Answer 1

IScriptArgs is aggregated on the Utils boss, so you would use it as follows:
In your C++ code:
Utils<IScriptArgs>()->Save(); // Saves the current set of scripting parameters on the context stack and creates a new current context, that has no parameters set.
// Now set up the parameters that you want to access from within your JavaScript as key-value pairs
Utils<IScriptArgs>()->Set(PMString("paramkeyname1"),PMString("ParamValueAsString1") );
Utils<IScriptArgs>()->Set(PMString("paramkeyname2"),PMString("ParamValueAsString2") );
// Call your script
Utils<IScriptArgs>()->Restore();    // Replaces the current existing context with the top context on the stack of saved contexts. In other words, returns the parameter stack to the Save() position.
In your JavaScript code:
if(app.scriptArgs.isDefined("paramkeyname1")) {
var yourvalueStr = app.scriptArgs.get("paramkeyname1")
