".Is there a way to stop the program's running until." No, there is no way to stop a function from running. A Flex app is essentially single threaded, from the developers perspective. You must have your alert box call a handler function, then in that function, complete whatever action you need based on the event.detail.

Here's what I've got... I have an 'if' statement that calls a boolean function -- problem is, that function pops up a Yes/No Alert window. In order to know what button the user clicked, the handler-function must be called from the Alert pop-up, thereby preventing the boolean function from returning a proper value based on the outcome of the Alert window... Lemme 'splain a bit better with an example: private myMainFunction():void { //many things going on here before we get to the 'if' statement below. if (myBooleanFunction()) { //set a local-to-this-function variable here. } else { //set a local-to-this-function variable to something else. } //More things going on here that need the above-referenced local-to-this-function variable to be set before they can run. } private function myBooleanFunction():Boolean { Alert.show("Do you want to do this?","Alert...",(Alert.YES | Alert.NO, this, alertHandler, null, Alert.NO); //Flex is expecting a true/false return HERE, but I can't give one because I don't know the result until the alertHandler has run. } private function alertHandler(event:CloseEvent):void{ if (event.detail == Alert.YES) { return true; //of course alertHandler isn't a boolean, so this doesn't work. } else { return false; //of course alertHandler isn't a boolean, so this doesn't work. } Of course the above example does NOT work, because the alertHandler function is of type void, and the myBooleanFunction doesn't return anything. So, how do I get the myBooleanFunction to return true/false based on the outcome of the alertHandler function? Is there any way to do this? If not, what's my alternative? Is there a way to stop the program's running until alertHandler sets a public variable, perhaps? What's the proper way to handle this? Thanks, Laurence MacNeill Mableton, Georgia, USA
