Problem using ControlSend.

[Vacca]

I've written a script to save a stream using Audacity, but, when it asks for the name that the stream should be saved as and I pass it a string consisting of today's date, most of the name gets truncated.

ie If I use: ControlSend("Save MP3 File As:", "", "Edit1", "20080613") the file will be saved as "20.mp3".

The only way that I have managed to get it to 'sometimes' save with a longer name, is to put a sleep command right after the ControlSend command. I have no clue why this might make a difference, but sometimes it does.

(Now that I try running it again, I'm always getting the truncation, with or without the sleep command)

Does anybody have any idea what might be happening here?

It might be worth trying another method like

ControlCommand("Save MP3 File As:", "", "Edit1","EditPaste", "20080613") though I wouldn't expect it to be any different.

You must have something in your script to delay before you send Enter I suppose. Maybe you could wait until the text is correct like this

$text = "20080613"
$rt = ''
while $rt <> $text
$rt = ControlCommand("Save MP3 File As:", "", "Edit1","GetLine",1)
sleep(40)
wend

Thanks Martin.

I'll try your suggestions.

ps ok It looks like it works consistently with the second method.

The only thing that worries me about that, is the possibility of an infinite loop, so I'll add a counter to stop it running away.

It definitely looks like it was a timing issue.

ok, I spoke too soon. Sometimes it works perfectly, and other times, nothing.

Very, very strange.

ARe you using this idea?

$text = "20080613"
$rt = ''
while $rt <> $text
$rt = ControlCommand("Save MP3 File As:", "", "Edit1","GetLine",1)
sleep(40)
wend

If so can you see that the text has been entered ciorrectly in the edit?

If you have put a counter in to stop waiting forever, can you see if the counter limit has been reached and if so print out the value of $rt? Or does the script sometimes fail even though $rt is correct?

Why always at the end of a loop there is a sleep() ? Is it helpful?

If the script is going to check the contents of the edit continually it seems unecessary to check as fast as AUtoIt can run, so I thought a delay would reduce the 'effort' a bit. But I don't think it is affecting the problem, do you?

[Vacca]

Oh man, am I ever embarrassed! I found a bug in my script that was sending an {enter} too soon and causing the timing difficulties. Removed that, and everything worked fine. Sorry chaps, but thanks for the help!
