The second parameter is the way the main window of the control program is displayed, and the possible values are:
Sw_hide//Hide main window after program startup
Sw_maximize//Maximize operation
Sw_minimize//Minimized operation
Sw_restore//Restores the maximized or minimized window to normal
Sw_show//Show main window at current position and size
sw_showmaximized//Activates the window and maximizes the operation
sw_showminimized//Activate the window and run it minimized
Sw_showminnoactive//minimized operation, but not activated
Sw_shownoactivate//above the window size runs, but does not activate
SW_SHOWNORMAL//Normal mode, general operation using this
In general, the second parameter takes Sw_shownormal, so that is no parameter run One.exe
WinExec ("One.exe", SW_SHOWNORMAL); the second parameter is just the parameter of the WinExec function, not the One.exe parameter.
