When I start a standard form app and type the line #include <shellapi.h> at the top of my form1.h, it sets off >100 errors! A lot of them are redefinition errors. If I don't include the include line, I get a function not defined error.

I have managed C++ application whixch works with SHFileOperation function. h-file begins with:

#pragma once

#include <windows.h>
#include <shellapi.h>

namespace ShellTest

BTW, you don't need ShellExecute in managed C++ application. Use Process.Start(StartupInfo*) function with ProcessStartInfo.UseShellExecute = true.

I tried adding in the <windows.h> line that you have and it worked the first time! Apparently some or all of the Windows API includes require the windows.h header to be included as well. Also, thanks for the additional info on the process object... C++ is so monsterous with all its libraries these days!
