Hey Anuj,
People tend to respond more to questions that have enough info to get to the root of the problem such as coding issues. This one is more of a system issue and perhaps I'm still missing some info because I don't understand exactly what you're trying to do, and it's tough to post your "environment". (I'm still feeling a bit jilted that nobody answered my question some time ago about browser scrollbars ;-) You SHOULDN'T be able to "look at swc file in the browser". You should be able to add the swc to the lib path of your project and then have access to those components (those inside the swc) in the design view in the custom folder. If you have added it, and can see the components in the custom tab of the design view then perhaps there is something wrong with your swc? I would suggest getting a well known swc, say flexlib.swc, and adding it to your lib path, and trying to use some elements from it. If that works okay, then look to your swc as the problem. Where did you get the swc? What type of component in the swc are you trying to use? Do you get build errors when you use any symbol or component? If it's a visual component, are you sure it should be visible in the application view you put it in? --Danny
