How to show something only on first run?

[hisefilo]

Hi guys, maybe a stupid question. How can I do to show a dialog only on the first run of a compiled plugin/app?

At this point I'm trying this, no luck. Maybe Im doing something really stupid!

reg myJSONObj = Engine.loadFromJSON("..//micSetup.js");

if(myJSONObj == "")
{

    myJSONObj = {
             "micGainSetup": -18,
              "lowCutSetup": 1,
             "firstRunDone": 0
               };
     Engine.dumpAsJSON(myJSONObj , "..//micSetup.js");

};

micSettingsPanel.showControl(true);

inline function onsaveMicSetupControl(component, value)
{
	if(myJSONObj.firstRunDone == 0)
	{     
		micSettingsPanel.showControl(true);

    } else
    {
	    micSettingsPanel.showControl(false);
    }
    
	myJSONObj.micGainSetup = micGainSetup.getValue();
	myJSONObj.lowCutSetup = lowCutSetup.getValue();
   	myJSONObj.firstRunDone = 1;
   	
   	Engine.dumpAsJSON(myJSONObj, "..//micSetup.js");
    
};

Content.getComponent("saveMicSetup").setControlCallback(onsaveMicSetupControl);

@hisefilo Save the file to the appdata folder

@d-healey It's already saving on appdata and Application Support

@hisefilo I don't like the use of the relative path, it seems to have potential to fail. Use the file system API, and the writeObject and loadAsObject functions

if(myJSONObj == "")

Does myJSONObj equal an empty string if loadFromJSON fails? Wouldn't it be undefined?

@d-healey you are right! myJSONObj never is ""
