How to minimize a child process ?

OS: Windows 2K Pro
Java 2 Platform Std. Ed. v1.4.0

I have an application with its main window running in full screen mode using  setFullScreenWindow.
I launch a native application based on user input using
Runtime rt = Runtime.getRuntime();
Process child = rt.exec("Notepad.exe", "c:\\boot.ini" );

The problem is that once the native application (Notepad.exe) is launched, my full screen window is minimized and the focus is moved to the Notepad.exe.

The questions are:
1. How can I launch the child process in a minimized window.
2. How can I keep my main full screen window maximized, and on the top of all other application (TopMost) and has the focus?

Thanks

Don't know of any Java API to do what you wish.
The only way I can think of is find a Windoze command that opens an application up already minimized, and call that using exec().

Have you tried bringing re-maximising your frame and bringing it to the front after notepad has fired up.

 ... and of course, as objects suggested you can monitor the "de-activated" window and bring it back to top again: http://home-1.tiscali.nl/~bmc88/java/sbook/0115.html

Hi
 
try this:
Runtime.getRuntime().exec(new String[] {"cmd", "/C", "start", "/MIN", "notepad", "c:/boot.ini"});

best regards

Why not open the boot.ini file in a text component in your application window? This would also be safer and more portable.

2objects:
your suggestion is suggestion only :)
Because java has only one way to launch other applications and this method hasnot any additional parameters to handle launching (minimazing and others), so your suggestion was obviously... but it's not solution :)

best regards
