You need to escape the characters properly.
It should be 'd:prog file 090422.xls'
Not UI related. Moving

If it asks you to save any changes, answer no. Serial number for sims deluxe. I usually close the file by clicking on the red 'X' at the top right corner. If it did ask for changes then you didn't follow these steps.

The space character in the path is the problem; use the Runtime.exec variant that takes a String[] as parameter. Also be sure to read the article by Daconta titled 'When Runtime.exec() doesn't'.

I think the problem has a different cause: the Excel file is simply not an executable by itself. Therefore, you can't launch it as a program.
There are (using Windows) two ways of handling this:
- with rundll32.exe; I just keep forgetting the complete parameters
- using 'cmd /c start xxx.xls'
The latter launches a hidden command window which executes 'start xxx.xls'. The 'start' part causes Windows to use the default program, which usually is Excel.
No idea how this works in Unix; I think it all depends on the desktop environment used (Gnome, KDE, ..).
Edit: just tried it with a file with spaces, cmd does not like that. I did find the complete rundll32 parameters: http://forums.sun.com/thread.jspa?threadID=699829&tstart=285

the spaces part would probably require wrapping in ' (i.e 'prog file')
Runtime.getRuntime().exec('cmd /c start D:'prog file'090422.xls');

Tried that of course - no go. Even if I open the start command from another command window, and let the tab completion add the quotes - still no go. It's an issue of the start command itself.

just tested it like this on vista, opened OK (changing D: to C:)
Runtime.getRuntime().exec('cmd /c start C:'prog file'090422.xls');

Ah, it only works if you put the quotes around the path parts that contain spaces. I tried quoting the entire path, as one would expect.
So the rundll32 solution is easier - it does the same* but only requires the quotes around the entire path, not each part.
* The main differences I found are:
1) rundll32 does not show an 'open with' window if there is no program associated with the file
2) rundll32 does not show an error if the file does not exist
Edit: tried it some more, and if the file path contains spaces, 'cmd /c start' needs quotes around everything after the drive specification. For instance C:'prog file090422.xls'. So if you use getAbsolutePath(), strip of the drive part, add quotes and add the drive part again, you're safe ;)

Download Excel File From Web

thanks for replies.
this is ok:
public static void main(String[] args) {
try{
// Runtime.getRuntime().exec('D:prog file090422.xls');
String[] cmdarray=new String[]{'cmd.exe','/c','D:prog file090422.xls'};
Runtime.getRuntime().exec(cmdarray);
// or Runtime.getRuntime().exec('cmd /c start ' 'D:prog file090422.xls');
}catch(IOException e){
e.printStackTrace();
}
}

Yup. But only if you are on JDK1.6+

String[] cmdarray=new String[]{'cmd.exe','/c','D:prog file090422.xls'};
Runtime.getRuntime().exec(cmdarray);
// or Runtime.getRuntime().exec('cmd /c start ' 'D:prog file090422.xls');


I've one clarifications to seek. '/c' in the argument tells cmd to execute anything that comes after it. Can we have more than 2 commands to execute using the above exec method ? if yes, then how do we do that ?
Thanks

I've read through the CMD help but it really says 'command' - singular.
You can use a .bat or .cmd file that executes these commands, then call 'cmd /c myfile.bat'; that's as far as I get.

It is damn easier......but can we control it in someway....
Suppose I open a worddoc using Desktop, can I know whether the doc is still open or if it is closed......
Atleast Runtime returns a process for which we can wait for. Can we do something like that using Desktop.

No you can't. That method does not block, nor does it return anything to identify the process with.

Thanks Rob.
So that makes it clear that we have to use Runtime or ProcessBuilder even when we have similar methods in the Desktop class.

If you want any control over the process, then yes. Desktop.open() is really 'fire and ignore'.
