Send randomly stops working when SendKeyDelay is low

Recommended Posts

Posted (edited)

I have a program that sends keystrokes to a window like so:

Opt("SendKeyDelay", 10)

WinActivate("MyWindow")

WinWaitActive("MyWindow")

for $x = 1 to 5
  for $y = 1 to 99
    Send(StringFormat("%d ", $x))
    ; Send(_StringRepeat(StringFormat("%d ", $x), 99) shows similar behavior
  Next
Next

I want to send out "1 1 1 1 1 " and "2 2 2 2 2 ", etc.

Now I can see that it starts okay, but often it will stop, and when one send command bombs, nothing further happens. For instance, if it stops at x=3, then "4 4 4 4 ..." and "5 5 5 5 ..." are not sent.

I've also tried using StringRepeat(..., 99) but am still seeing the same behavior.

Now I have another command about hitting an F11 key, and when that happens, the cache seems to reset.

Is there any way I can flush the cache after each Send?

And if not, are there any metrics on SendKeyDelay vs. probability of failure? I'm willing to accept some failures in return for getting enough data I need quickly.

I've tried replacing Send() with ControlSend() and also putting in a buffer such as sleep(100) but the hangup still seems to happen at the same rate. Any suggestions?

Thanks!

added example that stop at x=3 stops x=4/5, ControlSend/Sleep tries

AndrewSchultz,

Welcome to the AutoIt forums.

I cannot get the code to fail when using a simple editor - what sort of window is it that you are using when "Send"ing?

And I doubt SendKeyDelay is causing you any problems as you are using double the default value!

you are only sending 1 digit at a time, so the SendKeyDelay isn't actually being used at all.  If you were to build a string of numbers and send them all at once, THEN SendKeyDelay would be used between characters.

So, in your example, you would just need to add a sleep(10) after each Send() and not use SendKeyDelay.


hmm... I guess I have to have a signature...
