Here is my C# code in the ASP.NET page.

public static void DoConvert ( string sFile )
{
string cmd = "foo.exe" ;
string param = " /bar.txt" ;
Process myproc ; // <-- Error here
ProcessStartInfo startInfo = new ProcessStartInfo ( cmd , param ) ;
startInfo.CreateNoWindow = true ;
startInfo.WindowStyle = ProcessWindowStyle.Hidden ;
myproc = Process.Start ( startInfo );
//myproc.WaitForExit () ;
myproc.Close() ;
}

When I run it I get:
Compiler Error Message: CS0246: The type or namespace name 'Process'
could not be found (are you missing a using directive or an assembly
reference?)

I think this is because I need:

using System.ComponentModel;

But I can't figure out where to put it. I've tried several places but
still got the error. Any ideas?

Thanks!
 
vbMark,

You need to add a directive to use the System.Diagnostics namespace in
your page. You can also use the full name of the process and start info
classes, like this:

System.Diagnostics.Process myproc ; // <-- Error here
System.Diagnostics.ProcessStartInfo startInfo = new
System.Diagnostics.ProcessStartInfo ( cmd , param ) ;
startInfo.CreateNoWindow = true ;
startInfo.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden ;
myproc = System.Diagnostics.Process.Start ( startInfo );

Hope this helps.

Well now I'm getting a different error:

Error saving file: System.ComponentModel.Win32Exception: Access is denied
at System.Diagnostics.Process.StartWithShellExecuteEx(ProcessStartInfo
startInfo) at System.Diagnostics.Process.Start() at
System.Diagnostics.Process.Start(ProcessStartInfo startInfo) at
converter.WebForm1.DoConvert(String sFile) in c:\inetpub\wwwroot
\converter\default.aspx.cs:line 39 at ASP.default_aspx.Button1_Click
(Object Source, EventArgs e) in
http://localhost/converter/default.aspx:line 34

Is this because it can't run an executable or some other reason? Is this
how one is supposed to run an executable at the server?
 
vbMark,

This is the result of not having sufficient rights. By default, ASP.NET
runs under the ASPNET local account, which has a limited set of rights. If
anything, you need to impersonate a user that has the rights that your
executable needs to operate.
