No, it should be faster. Currently, if you set UseShellExecute to true, the command run is: $SHELL -c 'yourprogram yourparameters' MS seems to run 'cmd /c yourprogram yourparameters'. The diference is that cmd on windows also handles something like 'cmd /c file.pdf' by opening acrobat reader and stuff like that. My idea is to distribute a shell script with mono that first tries gnome-open or kfmclient and then defaults to $SHELL -c ... so that we achieve similar functionality as MS. When UseShellExecute is false, it's like running system (yourprogram yourparameters); -Gonzalo ___ Mono-list maillist - [EMAIL PROTECTED] http://lists.ximian.com/mailman/listinfo/mono-list

Hi,
I stumbled upon then same problem in my project after upgrading to Mono 0.31.
The workaround with UseShellExecute = false works, but I have noticed a considerable performance penalty. So I wonder:
1. Is the fact that arguments are not used without UseShellExecute a bug in Mono 0.31 release?
2. Is using UseShellExecute = false slower in comparison to UseShellExecute = true?
Thanks,
Ivan

I have the same problem now, as even the following simple application
doesn't work anymore in Mono 0.31 (it worked correctly in Mono 0.29):
8--
using System;
using System.Diagnostics;
class ProcessStart {
static void Main(string[] args) {
Console.Out.WriteLine(Trying to start: 'mono --version');
ProcessStartInfo psi = new ProcessStartInfo();
psi.FileName = mono;
psi.Arguments = --version;
Process p = new Process();
p.Start( psi );
}
}
8--
Instead of printing the version - it prints now the help for parameters
usage...
I've checked and the specified parameters (--version) are not passed to
the target program (mono) at all... Is there any workaround for this
problem?
I've tried the daily package mono-0.31.99.20040331.tar.gz, but it seems to
me, that method Process.Start doesn't work at all in this version ... even
without parameters... :(
What's happening?

Re: [Mono-list] Starting processes with parameters from Mono 0.31 and mono-0.31.99.20040331
Are you using Windows or Linux? As I understand UseShellExecute, when set to false, Process.Start() will treat the filename as a binary image and attempt to execute it directly. This is really the only option that makes sense under vanilla Unix. On Windows, when UseShellExecute == true, it causes Windows to use the windows shell to process the filename. If the filename is a document, Windows will attempt to use an appropriate application to open the document. GNOME and KDE both provide mechanisms equivalent to the Windows Shell from what I understand, but whether to use these or not (and how to choose which one if both are present) seems unclear. Rotor under Linux simply throws an exception if UseShellExecute == true.
