Check to see if another instance of IE is already open

[bobrivers2003]

I have a simple JFrame that includes a button that when pressed calls a method that opens Internet Explorer with a given url. It is possible to check if IE is already open and if so stops a new browser window from opening?

void openIE()
{
try {
Runtime rt = Runtime.getRuntime();
rt.exec("C:\\Program Files\\Internet
Explorer\\IEXPLORE.EXE

http://www.google.com");

} catch (Exception z){
System.out.println(z);
}

}

Thanks and Regards

Assuming you're using windows, you can access the process list with tasklist command and check wether a instance of IEXPLORE.EXE is running.

To be exact, the command would be

tasklist /fi "imagename eq IEXPLORE.EXE"

but you will need to check the output.
