[gme-users] runnning exe from GME dll

[Vijdan KIZILAY]

Hi Csaba,
I used CreateProcess().This really helps not to block my interpreter.

The process which I create from the interpreter goes on running while
the interpreter finishes. (That is what I want)

When  I create my process, I do not wait for created process to end
(functions below
are ignored). So interpreter does not block.

//WaitForSingleObject( pi.hProcess, INFINITE );
 //CloseHandle( pi.hProcess );

Thanks for help,
Vijdan
