It doesn't work without wait window, even if if i wait for 50seconds or more.

*-- state 7 = CONNCTED
*-- state 6 = CONNECTING
DO WHILE THISFORM.tcpwaage.OBJECT.state<>7
*-- wait until connected
ENDDO

the connection needs a user input, without this it doesn't work.

IF THISFORM.tcpwaage.OBJECT.state<>7
THISFORM.tcpwaage.OBJECT.CONNECT("192.168.100.222",1234)
WAIT WINDOW "Please press key"
IF THISFORM.tcpwaage.OBJECT.state<>7
*-- could not connect
ENDIF
ENDIF

When the wait window is removed, it doesn't work in runtime,
in VFP there is no problem, even without that wait window.
