Hello:
I have created a Desktop that interacts with a embedded db. I also
have crated a flash program that opens and runs itself in any web browser.

My inquiring is to find out if I can create a button to launch this flash program from my Java app?

Also is it possible to put the flash program in the db to
additionally control access to its code?

Please find attached a description of flash program to launch in browser.
Thanks

I found some code via Google years ago. It has lots of special code depending on what OS your executing on. I have no idea if the code will work on Linux or Mac today. I am currently using it in my WinXP apps.

/* Examples:
 *     BrowserControl.displayURL("http://www.javaworld.com")
 *     BrowserControl.displayURL("file://c:\\docs\\index.html")
 *     BrowserContorl.displayURL("file:///user/joe/index.html");
 *
 * Note - you must include the url type -- either "http://" or "file://".
