Running external program and capture output Shellexecute?

Hi,

I'm new here and I don't know if I'm posting this in the correct place.

I'm using Visual Studio 2003 and I have to create a windows application,
so I use the .NET windows forms application to do this.
My program has to use the Spin model checker, which I want to call as an
external program. So I want to run that program in a dos-box from within
my application and when it exits I want to read all the output it has
generated to use in my application.
Is there a way to do this?

I tried to use ShellExecute, but I couldn't get it to work.

Kind regards,

Marcel

If you do Windows-Forms you should also use the managed-API to do this
work...

#undef MessageBox

System::Diagnostics::ProcessStartInfo *si = new
System::Diagnostics::ProcessStartInfo();

si->UseShellExecute = false;
si->WorkingDirectory = S"C:\\";
si->FileName = "C:\\program.exe";
si->Arguments = "args";
si->RedirectStandardOutput = true;
System::Diagnostics::Process *p =
System::Diagnostics::Process::Start(si);

p->WaitForExit();
System::String *output = p->StandardOutput->ReadToEnd();
System::Windows::Forms::MessageBox::Show
(output);

Hi,

Jochen, your code worked for me only the rediriction of the output seems
to go wrong. When I run the program I want to call on the command prompt
output is created on the screen, but when I try to redirect it in the
way you suggest the output string remains empty.

I tried to redirect from StandardError, and I also tried to move the
WaitforExit to after the ReadToEnd clause, both without succes.

Any ideas on this?

Greetings,

Marcel
