Thank you very much to all the people who take time to reply for this post
I was heavily stucked with the same problem and can not access main mxml variable from the class I was missing heavily _root and _global facilities in as-2 But the kind advice of using *mx.core.Application.application * == *_root*helped me to solve my problem I want to say thank you for that regards, Jignesh Dodiya +91 99 7 99 56565 www.jigneshdodiya.com On 11/14/06, Gordon Smith <[EMAIL PROTECTED]> wrote:

It sounds like you're trying to set myVar without declaring it in the <mx:Script> of the <mx:Application>. In AS3, most classes (such as Application and your application subclass) are declared as non-dynamic, which means that you can only access variables on them if they have been declared at compile time. > I'm truly baffled as to why this completely fundamental aspect of actionscript has been so utterly scrapped in AS3. If you're referring to having non-dynamic classes and using them extensively in the Flash and Flex frameworks, this was done for performance reasons. It's one of the biggest reasons why AS3 is often 10x faster than AS2. If a variable is defined at compile time, then it can be accessed quickly by its offset (say, 12 bytes) within the instance, rather than slowly by name lookup. - Gordon ------------------------------ *From:* flexcoders@yahoogroups.com [mailto:[EMAIL PROTECTED] *On Behalf Of *Paul Carpenter *Sent:* Saturday, November 11, 2006 8:27 AM *To:* flexcoders@yahoogroups.com *Subject:* [flexcoders] Re: OK, seriously. Why can't I make a global var? It would not appear that you can actually instantiate a variable with Karl's "mx.core.etc..." convention. Am I wrong? Also, my variable is not actually coming from the Application.applicationlevel, as it's being gathered by a custom component at a child level. I've tried all the variations on how to reference directly into that component to grab the variable (i.e. Application.application.smtpWindow.email) but nothing works. Going from inside a component to the Application level is fine, but going the other way doesn't seem to work for me. I'm truly baffled as to why this completely fundamental aspect of actionscript has been so utterly scrapped in AS3. It's also kind of scary that no one has popped in with the "Duh, it's obvious! Do this...." Hmm. <pedantry>This is not technically a global variable. It is simply an instance var of the Application object.</pedantry>. - Gordon ________________________________ Subject: RE: [flexcoders] OK, seriously. Why can't I make a global var? You can use mx.core.Application.application.myVar = "hooray!"; if you really want to access a global variable like that. |< Karl Johnson Cynergy Systems ________________________________ After years (and years and years) of programming Flash, I'm used to being able to simply say: _root.myVar = "hooray!" and being able to see that variable anywhere. Why in God's green earth can't I do the same in Flex? I have a custom login component which is currently a child of the base app, sitting in a view state. All I want to do is grab one of the returned values that the login gets (emailaddress) and let other sections of my program see that. I cannot for the life of me figure this out. I see stuff about making static members of classes, referencing "parentApplication" etc. I am in no way a newbie to interactive development, and this is just insane. Within my first two days of using Flex I figured out how to create a complete login/registration system that talks to a DB, and figured out how to use the socket class to directly talk to my mail server and format a proper SMTP message, but I can't do this. Clear guidance would be appreciated before i pitch my G5 out the window.
