spawnl and NOWAIT

I use spawnl(_P_NOWAIT, <path_to_mshearts>); and hearts
will launch while letting my program continue.
I use the same statement with a simple program I made
using Devel.Studio Vis.C++ and it is launched synchronously
instead.
The program I made is a project in MicroSoft's Vis.C++, created as a Win32 Application. It is a simple dialog box which just has a button to end the program.
Why is spawnl ignoring the NOWAIT? Asynchronous spawning should work with a Win32 application right?

Thanks for any tips..

to be exact, the function call which works for hearts is:


_spawnl(_P_NOWAIT,"C:\\Progra~1\\hearts\\mshearts.exe"," ", NULL);

Why ? Limitation of the runtime library

Use

UINT ui = WinExec( "C:\\Progra~1\\hearts\\mshearts.exe", SW_SHOWNORMAL ) ;

if ( ui <= 31 )
{
 // some kind of error occurred
} else
{
  // spawned okay
}

I don't see any reason why spawnl() shouldn't be working.
