Strange behaviour with ProcessStart

[mcw.willart]

Hi,

I notice some strange behaviour with Process.start; when I start an
mmc-console,
e.g. Process.Start("c:\\tools\\AdminConsole.msc"); everything works
fine, but when I try to start it with the following code (using a
username and password) I get "The specified executable is not a valid
Win32 application".

ProcessStartInfo myProcess = new ProcessStartInfo("AdminConsole.msc");
myProcess.UserName = strUserName;
myProcess.Password = password;
myProcess.Domain = "<domain>";
myProcess.FileName = "AdminConsole.msc";
myProcess.UseShellExecute = false;
Process.Start(myProcess);

Anyone any idea?

Greetings,

Mario

As a complete guess - can you pass it a username and password on the command
line? If not that might be where your problem lies.

myProcess.UseShellExecute = false;

This line is your problem.

Change it to true instead, and it'll be fine.

Jon,

I tried your suggestion, but then I get "The Process object must have
the UseShellExecute property set to false in order to start a process
as a user".

Make it:

myProcess.FileName = "mmc.exe";
myProcess.Arguments = "c:\\tools\\AdminConsole.msc";

as a user".

In that case you'll need to specify the executable to use, as per
Willy's post.

Jon,

the UseShellExecute property set to false in order to start a process
as a user".

You've got to call the exe directly with aproppriate command line
parameters. The shell-execution doesn't work with password and username. I
don't know why, but that's what the docs say.

Make it:

myProcess.FileName = "mmc.exe";
myProcess.Arguments = "c:\\tools\\AdminConsole.msc";

Willy,

that did the trick! I had to pass the msc as an argument, I didn't
know that.

Thanks,
