Steve348 Posted March 2, 2010 Share Posted March 2, 2010 Autoit Gurus, I am trying to delay keystrokes to a DOS program running in a DOS window on a Windows 2K system. The delay is required to wait for things to happen (a test to complete) on an external piece of hardware controlled by the DOS program. The basic script is as follows: Func Do_Button_4() $Menu_Mouse_Pos = MouseGetPos() ; Save current mouse position WinActivate($win) Send("fc 40 {enter}") Send("la {enter}") Send("x2_dig_test.out {enter}") Send("fc 10 {enter}") Sleep (4000) ; Wait for test to complete Send("vt {enter}") Passit() WinActivate($win_2) ; Reactivate menu window MouseMove($Menu_Mouse_Pos [0], $Menu_Mouse_Pos [1], 0) ; Restore beginning mouse position EndFunc ; Do_Button_4 "x2_dig_test.out" loads the test file and takes about 5 seconds to complete. "fc 10" starts the test. The test takes about 2.5 seconds to complete so need to Sleep during this time. "vt" queries for test result status. The Passit()function reads the status and determines pass/fail. The current code appears to blow right past the "fc 10" with ZERO delay. If I change the Sleep parameter to "14000" the DOS program pauses at the correct point but only for 10 seconds not the 14 seconds it is supposed to be! Does anyone have any ideas of what I am doing wrong? This seems so simple but doesn't appear to be working! Thanks, Steve Link to comment Share on other sites More sharing options...
99ojo Posted March 2, 2010 Share Posted March 2, 2010 (edited) Hi, i can't reproduce or say anything about the sleep behaviour. Haven't had serious problems. But if you are afraid of, you may use function timerinit () and timerdiff () and code your sleep. It may 'tick' better: $start = TimerInit () Do $sleep = TimerDiff ($start) Until $sleep > 14000 ; 14 seconds Msgbox (0,"", "Code sleeps for " & $sleep & " ms!") ;-)) Stefan Edited March 2, 2010 by 99ojo Link to comment Share on other sites More sharing options...
jchd Posted March 3, 2010 Share Posted March 3, 2010 Welcome to the AutoIt forum! You say the test file takes around 5 seconds to load, but your code shows you're Send()ing the next keystrokes immediately. They are likely to be bufferd by DOS at this stage, but if the test program (which also needs a 2.5 seconds to run) has the idea of resetting (flushing) the keyboard queue, your input gets out of sync. Func Do_Button_4() $Menu_Mouse_Pos = MouseGetPos() ; Save current mouse position WinActivate($win) Send("fc 40 {enter}") ; <-- doesn't this need some time to have the dust settled as well? Send("la {enter}") ; <-- ditto Send("x2_dig_test.out {enter}") ; <-- that takes 5+ seconds, right? Sleep(6000) ; better late than sorry Send("fc 10 {enter}") Sleep (4000) ; Wait for test to complete Send("vt {enter}") Passit() WinActivate($win_2) ; Reactivate menu window MouseMove($Menu_Mouse_Pos [0], $Menu_Mouse_Pos [1], 0) ; Restore beginning mouse position EndFunc ; Do_Button_4 This wonderful site allows debugging and testing regular expressions (many flavors available).

Steve348 Posted March 3, 2010 Author Share Posted March 3, 2010 Thanks for your input. You are correct in that DOS is apparently buffering the keystrokes. Any idea how big that buffer is? The DOS program DOES NOT clear the key buffer in between commands so this is not an issue. However, as you mention the 4000 delay may be taken up with program loading therefore it appears to be non-existent when I am intending it to occur. I will try your suggestion and add a sleep delay after the program loading. Steve Welcome to the AutoIt forum!
