Function name : CreateProcess

Group: Process and Thread - Library: kernel32

Code examples:

Start an executable from VFP application by using the CreateProcess
Starting external program from VFP and waiting for its termination
Running MSDOS Shell as a child process with redirected input and output (smarter RUN command)
How to make application automatically close all documents it opened
How to prevent users from accessing the Windows Desktop and from switching to other applications

BOOL CreateProcess(
  LPCTSTR lpApplicationName,           // name of executable module
  LPTSTR lpCommandLine,                // command line string
  LPSECURITY_ATTRIBUTES lpProcessAttr, // SD
  LPSECURITY_ATTRIBUTES lpThreadAttr,  // SD
  BOOL bInheritHandles,                // handle inheritance option
  DWORD dwCreationFlags,               // creation flags
  LPVOID lpEnvironment,                // new environment block
  LPCTSTR lpCurrentDirectory,          // current directory name
  LPSTARTUPINFO lpStartupInfo,         // startup information
